The utility model is achieved in that

The utility model provides a kind of decontaminating apparatus and decontaminating apparatus pressure switch, wherein,

Described decontaminating apparatus comprises: pipe arrangement is connected in the self water feeding facility, by giving water controlling equipment, make temperature or cold clean water often be stored in decide the clean water service tank of water level; Pipe arrangement is connected in its suction side, to cleaning the pump that water applies high pressure; At the exhaust end of this pump, the clean spray gun that pipe arrangement connects, have the open and close controlling of cleaning the water ejection by cleaning the opening and closing operations of spray gun, makes electric current inflow pump control loop, the running of far distance controlled pump by preventing the check (non-return) valve that the pump adverse current is used;

It is characterized in that,

Described pressure switch possesses and has: pipe arrangement is connected in check (non-return) valve and cleans the body in succession of the pipe arrangement in succession between the spray gun; Be embedded in succession in the body, have the pump that pipe arrangement is connected in the return pipe of cleaning the water service tank; Be equipped in this pump, open and close the valve of pipe arrangement in succession of the valve gasket of body in succession sliding freely; One end is fixed in this pipe arrangement valve in succession, and the other end is derived in the motion bar of pump outside; When clean spray gun is closed operation, make the residual pressure in the pipe arrangement in succession keep institute's definite value, stop the to close valve of described pipe arrangement in succession with valve, open and close and be equipped on the residual voltage maintenance of leading in the backwater mouth of pipe of cleaning the water service tank and detect holding device with the pressure of valve; And face and be fixed in succession that pipe arrangement sets with the motion bar of valve, a pair of switching contact on the pump control loop that moves with the switching of valve along with pipe arrangement in succession;

Pipe arrangement in succession between described check (non-return) valve and clean spray gun, with the opening and closing operations of cleaning spray gun, make in the pipe arrangement in succession fixed pressure oscillation, cause its pipe arrangement valve on-off action in succession, when clean spray gun is closed operation, the residual pressure in the pipe arrangement will keep keeping institute's definite value with valve greater than residual voltage in succession, thus, stop described pipe arrangement in succession with valve close valve the time, pipe arrangement will be with the on-off action with valve of pipe arrangement in succession, open and close controlling pump control loop in succession.

Supply pump temperature or cold clean water clean the water service tank, use opening boiler or hermetic type boiler and warm water tube.

If the former, the hot water inner bag of boiler is by giving the ball-cock assembly of water controlling equipment, and pipe arrangement is connected in the self water feeding source of running water etc., in the open atmosphere of hot water inner bag inside.Then, the suction side of pump is connected in the feed water inlet of the hot water inner bag of boiler with pipe arrangement in succession, and the backwater mouth of pipe that the pressure of pressure switch detects holding device then is connected in the superjacent air space portion of warm water tube with pipe arrangement.

The latter, the hot water inner bag pipe arrangement of boiler is connected in the self water feeding source of running water etc., in the airtight atmosphere.Be connected in the warm water tube of the floating drum valve of this hot water inner bag outside by built-in pipe arrangement, supply pump is cleaned water, therefore, and the suction side of pump, be that pipe arrangement is connected in the warm water tube, the backwater mouth of pipe of the pressure detecting retainer of pressure switch then pipe arrangement is connected in the superjacent air space portion of warm water tube.

In addition, prevent that in order to reach pump from sucking low temperature and cleaning water and the easier and more efficient purpose of carrying out of hydrophobic operation that makes in the pump, pipe arrangement has connected the float-ball type check (non-return) valve that utilizes buoyancy to make mouthful switching that continues of pump side.

Also be, the pipe arrangement in succession of the suction side of pump and derivation bottom the hot water inner bag of boiler, leading section has between the drainage piping of sediment discharge valve, have body and pass through gripper shoe and the ball float of mounting with its inside, and the vertical direction pipe arrangement has connected the have or not lifting of its ball float because of the buoyancy of water in the body in the body, and opens and closes the float-ball type check (non-return) valve that pump side continues mouthful and be its feature.

At this moment, clean the water service tank no matter be aforesaid opening boiler, or the hermetic type boiler, or warm water tube, its clean water service tank and pump suction side be connected and the pressure of pressure switch detects the backwater mouth of pipe of holding device and being connected all with aforementioned identical of clean water service tank.

After cleaning the operation end of a period, turn off switch pump, after the residual water in the clean pipe arrangement that spray gun is emitted with pump is connected of use, turn off clean spray gun again.Therefore, the pressure pipe arrangement in succession that detects holding device keeps being all closing state with valve with the residual voltage in the valve and the backwater mouth of pipe.(Fig. 2 a) at this moment, move with the closing valve of valve according to pipe arrangement in succession though the other party of pump control loop opens and closes contact (ON with), but cut, so pump shuts down because of switch pump.

About the preparation that the clean operation under this state begins, at first open switch pump, make the pump running.And the clean water (during the boiler running is warm water, is cold water when stopping) that is applied in high pressure is spued in the pipe arrangement of aforementioned clean spray gun connection.But because of clean spray gun is a closed condition, so the pressure in the pipe arrangement raises into high pressure.This pressure is in case surpass the setting pressure of being decided, pipe arrangement will significantly be opened with valve in succession, and a side's of aforementioned then pump control loop switching contact (OFF uses) will move it, and the pump control loop is then opened a way, the energising of leading to the pump motor is interdicted, and stops the running (shown in Fig. 2 b) of pump.

At this moment, because aforesaid residual voltage keeps also opening with valve, clean water by the return clean water service tank of return pipe by the high pressure that pump spues, so the pressure in the pipe arrangement in succession between pump and the clean spray gun can not produce abnormal pressure.

The clean water that spues with pump returns clean water service tank by return pipe, pressure in the pipe arrangement and then reduces in succession, in case drop to the setting pressure that residual voltage keeps using valve, residual voltage keeps with the then inaccessible backwater mouth of pipe of valve, residual water is closed within the pipe arrangement in succession between check (non-return) valve and the clean spray gun, with keep fixed residual pressure.(shown in Fig. 2 c) be residual pressure according to this, has stoped toward pipe arrangement in succession with the trend of the closed circuit side of valve, and with the opening of certain degree, it has been stopped, less than closing valve.So it is motionless that the other party of pump control loop opens and closes contact (ON uses), the running of pump still is halted state.(open switch pump, and open under the situation of cleaning spray gun, pipe arrangement is not opened with valve in succession, and with the state of Fig. 2 a, cleans water and spues because of the running of pump) at once.

If with the beginning of this state (the residual voltage hold mode of Fig. 2 c) with clean operation, open and clean spray gun, so aforementioned residual water will be ejected by clean spray gun, low and even the disappearance of residual pressure in aforementioned pipe arrangement in succession, so after pipe arrangement cut out with valve in succession, aforementioned other party opened and closed contact (ON with) and moves it, the pump control loop is by closed circuit, then pump turn round it (shown in Fig. 2 a).

Then, when as long as clean next time spray gun cuts out, and the anxious commendable increase height of the pressure in the pipe arrangement in succession between the aforementioned check (non-return) valve, make in succession pipe arrangement with valve more than setting pressure, its valve is significantly opened, an aforementioned side opens and closes contact (OFF with) and moves it, and the pump control loop is opened a way then, and the running of pump stops.(shown in Fig. 2 b) then, residual voltage keeps also opening with valve, closes to be encapsulated in interior the press water of pipe arrangement in succession by return pipe, returns clean water service tank.Pressure in the pipe arrangement is low gradually in succession, keeps setting pressure with valve in case reach residual voltage, and this valve will be closed, and makes in succession in the pipe arrangement institute's level pressure power by remaining, and stops toward pipe arrangement in succession with the valve direction activity of closing of valve.(shown in Fig. 2 c)

When clean, clean the hot water inner bag of the boiler of water service tank, cause and by in succession to the pipe arrangement in the self water feeding source of the running water of water controlling equipment etc., make clean water be stored in often decide water level, so also be full of clean water often in the pipe arrangement in succession in conjunction with the vertical direction of the drainage piping of the pipe arrangement in succession of pump suction side and boiler.For this reason, the ball float of float-ball type check (non-return) valve that is equipped on the pipe arrangement in succession of this vertical direction bears and cleans the buoyancy that water produced and rise the mouth that continues of inaccessible pump side.Consequently, the high temperature warm water of prevention pump absorption boiler upper lateral part side is also cleaned water with the low temperature of boiler following side and is absorbed simultaneously; And prevent to descend with the clean coolant-temperature gage of its absorption.

After clean operation ended, as long as open the sediment discharge valve, the hot water inner bag that is accommodated in by drainpipe and boiler was communicated with the interior residual water of pipe arrangement in succession of stating vertical direction before, will be with falling under the water level in the hot water inner bag, and similarly water level also reduces.Consequently, ball float is along with water level descends, and buoyancy disappears and descends gradually, and mouthful quilt that continues of pump side is open, so the residual water in the pump comes and goes around the ball float, the clean water that is derived in sediment discharge valve and the boiler is discharged from from the sediment discharge valve simultaneously.

Be with, the utility model has solved problem points and the difficulty that is run on the prior art, and provide with pressure check in the pipe arrangement and maintenance, the structure of the control device of open and close controlling pump control loop is given merely, simplicity, and can significantly reduce number of spare parts and the upright formality of group, make device make laborsavingization, no longer include malfunction and fault and take place, reduce cost.Even, can prevent that pump from sucking low temperature and cleaning water, make the hydrophobic operation of boiler and pump easier and efficient, decontaminating apparatus and this decontaminating apparatus pressure switch of the running of far distance controlled pump are purpose according to the switching of cleaning spray gun.

Following conjunction with figs. describes embodiment of the present utility model in detail:

Figure 1 shows that the pipe arrangement/wiring system diagram of the decontaminating apparatus of the utility model embodiment.

Figure 2 shows that the pressure of pressure switch of the present utility model detects the action specification figure of holding device.

Figure 3 shows that the control loop figure of pump of the present utility model and boiler.

Figure 4 shows that vertical sectional drawing of float-ball type check (non-return) valve of the present utility model.

Figure 5 shows that the plane of the float-ball type check (non-return) valve of Fig. 4.

With reference to shown in Figure 1, the 1st, the shell of decontaminating apparatus, and the boiler 2 of the inner clean water service tank that is provided with warm water or cooling water with will clean water and apply pump 5 pipe arrangements that high pressure spues then and be connected.

The hot water inner bag 2a of boiler belongs to the style of opening that opens at atmosphere, and by the floating drum valve of feedwater control device, pipe arrangement is connected in the waterworks 4 in self water feeding source, and 2b is the burner that heating is contained in the water in the hot water inner bag.

Pump 5 is by CD-ROM drive motor 6 running, and its suction side is connected in the admission port of the hot water inner bag 2a upper lateral part of boiler by pipe arrangement 7, and exhaust end is the check (non-return) valve 8 by preventing that the pump adverse current from using then, and connecting to possess with pipe arrangement 9 in succession has the clean spray gun 10 that opens and closes handle.The 11st, connect the high-pressure hose of pipe arrangement 9 and clean spray gun 10 in succession.

Clean spray gun 10 and be to spray and is pushed and the clean water of high pressure that arrives, clean then by pump 5.But, utilize the pressure oscillation of the pipe arrangement in succession 9 that produces with its opening and closing operations, by the pump control loop, be able to far distance controlled pump motor 6.

The running of control loop 12 control boilers 2 and pump 5.As shown in Figure 3, control loop 12 is being connected in series AC power E, boiler switch BSW, thermostat contact SC and burner regulating relay BCR.Therefore, as long as connect boiler switch BSW, burner regulating relay BCR promptly moves it, and the burner point is got angry then, and boiler 2 is started running.Then, by the thermostat contact SC that moves by the check signal that is equipped on the temperature inductor SS in the hot water inner bag 2a, the burnings combustion of control burner, make the interior warm water of hot water inner bag 2a be maintained often fixed design temperature.

On the other hand, this control loop 12, the normally-closed contact Xb of power supply E, switch pump PSW, relay X and the coil 6MC of pump motor 6 usefulness electromagnetic contactors are being connected in series, so when relay X is failure to actuate, as long as open switch pump PSW, just can be according to the excitation of using the coil 6MC of electromagnetic contactor by the motor of normally-closed contact Xb, its switching meets gas figure and is closed condition, does not do demonstration, pump motor 6 is driven, and pump 5 is turned round.

In addition, the OFF of power supply E, pump motor is connected in series with opening and closing contact 6a and relay X, and for this OFF with opening and closing for the 6a of contact, the normally opened contact Xa of relay X is being connected with it with opening and closing contact 6b series connection loop in succession side by side with the ON of pump motor, and what form a relay X oneself keeps the loop.Then, OFF is with opening and closing contact 6a, for being connected of relay X, often be in the position of open circuit, ON then often is at closed circuit position with switching contact 6b on the contrary.

Therefore, when opening switch pump PSW, make when pump 5 runnings, as long as OFF produces action with switch contact 6a, close the loop circuit, the coil of relay X promptly is energized, and relay X produces action.Thereupon, its normally-closed contact Xb opens, and motor is interdicted with the energising of the coil 6MC of electromagnetic contactor, so it opens and closes contact and start, and the pump motor is not driven, and pump 5 stops to move.At the same time, because of the action with relay X, its normally opened contact Xa closes, thus even OFF puts unlatchings with opening and closing contact 6a homing, relay X by be at ordinary times closed circuit ON with opening and closing contact 6b, be energized, continuation moves.(pump 5 is still halted state)

When this pump 5 was halted state, as long as ON opens the loop with opening and closing contact 6b action, the energising of the coil of relay X was promptly interdicted, and the action of relay X is stopped.Thereupon, its normally-closed contact Xb transfers to by opening and closing, thus motor with the coil 6MC of electromagnetic contactor by excitation, the running of pump 5 is opened again.(state that switch pump PSW is still out)

The pair of O NOFF of the pump motor 6 of aforementioned control loop 12 utilizes to make pressure in the pipe arrangement 9 in succession produce change with the opening and closing operations of cleaning spray gun 10 to be unlocked with opening and closing contact 6a6b.

That is this pair of O NOFF constitutes pipe arrangement and is connected in pipe arrangement 9 in succession with opening and closing contact 6a6b as shown in Figure 1, and the part of the pressure switch 13 of moving with the pressure oscillation of institute's definite value in its pipe arrangement.

Therefore, pressure switch 13, be by checking pressure oscillations in the pipe arrangement in succession 9 to move then and making residual pressure in its pipe arrangement keep the pressure of institute's definite value to detect holding device 13A and move, state pair of O NOFF before the driving by control loop 12 control pump motors 6 and constituted with switching contact 6a6b with its action.

Aforementioned pressure detects holding device 13A, and as shown in Figure 2, possessing has: pipe arrangement is connected in the check (non-return) valve 8 of above-mentioned pipe arrangement in succession 9 and the pipe arrangement in succession 14 of the part between the clean spray gun 10; Have and lock chimericly by the sheet in succession 15 of pipe arrangement in succession, pipe arrangement is connected in the pump 17 of the backwater mouth of pipe 16 of the hot water inner bag 2a of boiler; Be equipped on sliding freely in this pump, open and close the valve 18 of pipe arrangement in succession of the valve gasket 14a of pipe arrangement 14 in succession; One end is fixed in pipe arrangement valve 18 in succession, and the other end is then derived the motion bar 19 of pump 17 outsides; And make the residual pressure of cleaning in the pipe arrangement in succession 9 of spray gun 10 when closed operation keep institute's definite value, be equipped on this in succession in the backwater mouth of pipe 16 of pipe arrangement with the hot water inner bag 2a that closes the boiler that valve should stop of valve 18, and switching residual voltage maintenance usefulness valve 20.

Aforementioned OFF is the motion bar 19 that faces with pipe arrangement activity with the switching of valve 18 in succession (moving up and down) with opening and closing contact 6a and ON with opening and closing contact 6b, and might set contiguously.

Above-mentioned pipe arrangement in succession is by the 18a of switching portion that opens and closes the valve gasket 14a of pipe arrangement in succession with valve 18 and is embedded in switching portion, forms along the sliding part 18b of pump 17 inner peripheral surface above-below direction slips.The 21st, push pipe arrangement valve 18 in succession, and make the compression spring of valve gasket 14a obturation, the 22nd, be embedded in the inaccessible face in top of pump 17, there is the pushing of spring 21 following side, and can adjust the adjustment valve of its pushing force, the 23rd, at the inner peripheral surface of pump 17, the lifting position regulation block the when pipe arrangement in succession of the section of being shape is done with starting of valve 18.

Residual voltage keeps with valve 20 between the screw 24 and pushing spring 25 of the backwater mouth of pipe 16 that is entrenched in pump 17.The 26th, the Flow-rate adjustment of the discharge amount of returning of the edulcoration water of the hot water inner bag 2a of restriction from the backwater mouth of pipe to boiler is used the aperture.27 is ends by screw 24, is connected in the return pipe of the backwater mouth of pipe 16, and the other end is then in succession in the discharge outlet 2c of the hot water inner bag 2a following side of boiler.Therefore, in this case, the return pipe of hot water inner bag 2a and the drainpipe of boiler become and are combined into one.

The pipe arrangement 7 of the feed water inlet of the hot water inner bag 2a of connection boiler and the suction side of pump 5, as shown in the figure, the upper side end that is connected the pipe arrangement 29 of float-ball type check (non-return) valve 28 with pipe arrangement links to each other, then communicative engagement is in the return pipe 27 that connects the discharging of boiler mouth in the lower side end of this pipe arrangement 29, and the junction surface pipe arrangement of this two pipe arrangement is connected in configuration sediment discharge valve 30 thereunder.

Ball float check (non-return) valve 28 as shown in Figure 4, is body 28a and the ball float 28b that is connected in pipe arrangement 29 by pipe arrangement, and gripper shoe 28c constitutes.Be by quadrate part under the broadness of sediment discharge valve 30 sides in the body 28a, with and the suction side upper portion narrow flow path of the pump 5 that continues, 28e forms.The chimeric body 28c inner peripheral surface that is disposed near broad stream 28d following side of gripper shoe 28c outer peripheral face.Ball float 28b then mounting on this gripper shoe 28c.Gripper shoe 28c is because of side opening in it is the baked donut type, so set an amount of aperture in the support portion in the outside sometimes.

Pipe arrangement 29 is by discharge outlet 2c, be communicated with boiler hot-water inner bag 2a, so as long as import water in the hot water inner bag 2a its water level is risen, the water level in the pipe arrangement 29 also can rise with work, ball float 28b accepts its buoyancy makes the stream in the body 28a rise the narrow flow path 28e of occlusion pump 5 suction sides.

Therefore, when common clean operation, boiler bottom water at low temperature can not be inhaled into pump 5.

On the other hand, after clean operation ends, for hydrophobic, as long as open sediment discharge valve 30, warm water in the hot water inner bag 2a of boiler or cold water will be discharged toward outside, its water level decline, and the water level in the pipe arrangement 29 is also along with similarly descending.Ball float 28b also descends, thus the narrow flow path 28e that closed by plug in the body 28 will open, the water in the pump 5 also with boiler in water with, carry out hydrophobic operation from sediment discharge valve discharge outside.

The decontaminating apparatus relevant with the foregoing description, the far distance controlled of the running of its pump 5 is that the action of being put down in writing in the project with above-mentioned effect is being carried out.

That is, open switch pump PSW, make pump 5 runnings, clean spray gun and open, the sparging water purification is cleaned operation then.In case the end of job is closed and is cleaned spray gun 10.Pressure in the pipe arrangement in succession 9 between check (non-return) valve 8 and the clean spray gun 10 will be pressed (for example 80kg/ square centimeter) height than the guttation of clean water, reach the setting pressure (for example 90kg/ square centimeter) of pipe arrangement usefulness valve 18 in succession.Then, pressure switch 13, is interdicted toward the energising of pump motor 6 then by control loop 12 toward the OFF direction action of pump motor 6, and pump 5 shuts down.(switch pump PSW is still at initial state).

In a single day the running of pump 5 is stopped, pressure in the aforementioned pipe arrangement in succession 9 will descend gradually, but, in its pipe arrangement, because kept being held with the residual pressure of closing valve institute definite value (for example 10kg/ square centimeter) of valve 20 by residual voltage, in the past the ON direction of the pump motor 6 of pressure switch 13 move and will be stopped.(pump 5 is still in halted state)

Clean spray gun and open once again when next time, the residual pressures in the pipe arrangement 9 will soon be emitted in succession.So pressure switch 13 toward the ON direction action of pump motor 6, then by control loop 12, makes 6 energisings of pump motor, pump 5 turns round once again.After cleaning operation and ending, turn off switch pump PSW, open and clean spray gun 10, emit the residual water in the pipe arrangement 9 in succession then, make the residual pressure in this pipe arrangement remain zero.

The pressure of pressure switch 13 detects holding device 13A, have and set the backwater mouth of pipe 16 that residual voltage keeps using valve 20, and the return pipe 27 with the hot water inner bag 2a that leads to boiler is connected with it, therefore also has the danger of generation abnormal pressure in the pipe arrangement of the exhaust end that prevents pump 5 simultaneously.It is the function of so-called pressure-relief valve (unloader valve).So, there is no need to set again a common pressure-relief valve.

As for the above embodiments, though the clean water supply mean that leads to pump 5 is described to be to use by giving water controlling equipment, the hot water inner bag that is connected in the self water feeding source is the opening boiler that opens in the atmosphere, but be not limited thereto, use is connected in the self water feeding source, and the airtight boiler of the airtight atmosphere of hot water inner bag or the built-in warm water tube that is connected in its feedwater control device by pipe arrangement also should be all right.At this moment, certainly, the suction side of pump 5 is that pipe arrangement is connected in the warm water tube, and in addition, 16 of the backwater mouths of pipe of pressure switch 13 are the superjacent air space portions that pipe arrangement is connected in the warm water tube.

Moreover the formation of pump control loop also need not be defined in the thing shown in the foregoing description, so long as the suitable thing of same function is all replaceable.
