Description

A kind of water-saving closet by-pass valve control

Technical field

The present invention relates to water-saving closet applied technical field, especially before relating generally to me at the number of patent application of China be: publication number is that CN 102864830A announced on January 9th, 2013, be CN102720256A with publication number, on October 10th, 2012 announce two domestic patent applications, and the patent No. is the PCT patent application of PCT/CN2013/001035.

Background technology

Current most of closet, except the new-type closet of my application, relates to apparatus of the present invention technical scheme hardly.

Art solutions before me, closet utilizes human bady gravitational, water tank one outlet conduit valve is controlled by bracing wire, discharge does not have the tap water of pressure, simultaneously also by some gravity of bracing wire conversion people, pull tank for excrement pan pitch brace, although above advantageous is in the increase of tank for excrement pan discharge pressure, but in order to reach better effects, closet gravity conductive plate needs the distance that moves up and down larger, so people comfortable and custom can be bad at one's leisure, and if the lighter child of body weight result of use is slightly poor especially, and toilet bowl structure can more complicated.

Publication number is the patent application technical scheme of CN102864830A, closet uses water as with being divided into three kinds, and the first makes closet piston decline and requires to realize at first, and the second realizes piston and rotates, the third toilet flushing, the control of three kinds of closet water not easily better controls.

Summary of the invention

Tank for excrement pan of the present invention adopts two or more water tank, decreases a part of parts composition of tank for excrement pan, two and with upper water box, arranges corresponding water supply volume as required.

Economizer water tank for excrement pan of the present invention, mainly comprise seal-off pressure cylinder barrel (4), piston (5), pitch brace (3), cylinder barrel enters, by-pass valve control on outlet conduit and pipeline, flow control valve (28), tank pipe also comprises one-way cock (29), water tank of the present invention is made up of two water tanks, inlet channel (2) is had outside a cylinder barrel (4), inlet channel (7), one-way cock (29) on pipeline (7), outlet conduit (6) and control its valve (8), inlet channel (23) is had outside another cylinder barrel, inlet channel (22), one-way cock (29) on pipeline (22), outlet conduit (21) and control its valve (8), pitch brace is connected with piston, through cylinder barrel one end, water inlet main conduit (1) there is by-pass valve control (27), flow control valve (28).

The flow control valve (28) of trunk inlet channel can the amount of water of regulable control water tank unit interval, one-way cock (29) on inlet channel ensures that water can only enter two cylinder barrels (4) by water inlet main pipeline (1), and the water of two cylinder barrels can not be circulated by pipeline (7) and pipeline (22) when cylinder barrel outside water outlet.

In cylinder barrel inner carrier both sides due to piston side is connected with pull bar (3) and pull bar through cylinder barrel, so the piston pressure area that has pull bar side to be subject to water is than not had pull bar side just in time few through the circular section area of the pitch brace of water tank, so when water tank water intake pipeline valve (27) is opened, each inlet channel has identical High-Pressure Water, if water tank piston is not at the side water tank that piston is stressed less, namely pitch brace does not pass water tank completely, current will promote piston and move, pull bar is made to pass water tank completely, then piston rest.

Open uniform pressure water source in water tank inner carrier both sides simultaneously, water tank cylinder barrel is stretched out in pull bar one end that piston side connects, then utilize pressure suffered by piston both sides identical, the situation that pressure is different, hydraulic pressure auto-controlling piston moves, have and overcome technology prejudice feature, because the cylinder that we see in reality, oil cylinder, when piston both sides are subject to identical atmospheric pressure simultaneously, piston is all static, pull bar eliminates bracing wire, spring controls, the apparatus structure making water tank and gravity conduction control bracing wire is obtained for the simplification greatly of structure, there is no the result of GRAVITY CONTROL pull bar, closet gravity conductive plate dropping distance can be reduced to a few millimeter greatly, people can be made to produce beyond thought stable comfort at one's leisure, and child also can reach better effects when using.

Tank for excrement pan of the present invention, pitch brace is not connected with any bracing wire, the pull bar stretching out cylinder barrel part stretches not by the spring effect beyond hydraulic pressure in cylinder barrel, water tank does not discharge the pipeline of the useless current of closet so not to the misgivings of discharging current process, compared with the tank for excrement pan of prior art, there is the simple advantage of obvious structure, and be greatly conducive to the structure of closet gravity conduction by-pass valve control device and the obvious improvement of function, for the requirement of chamber pot flushing water pressure, can directly be realized by the method increasing inlet channel hydraulic pressure.

The present invention, by a hydraulic controlled valve, controls two outlet conduit switches, and ensures that the water discharging time of controlled two outlet conduits is later than another outlet conduit.

The by-pass valve control of closet, comprise valve cavity (31), flow control valve (11) on cavity inlet and outlet pipe lines and inlet channel, cavity outer spring, valve plug (15) in cavity, valve plug pull bar, in described valve cavity, there is inlet channel (10) cavity side and regulates the flow control valve of its flow, cavity opposite side has two groups of inlet and outlet pipe lines, described valve plug there are two grooves (14), pull bar (17) one end is connected with valve plug, cavity is stretched out in one end, when pull bar stretches out cavity completely, cavity often organizes an inlet and outlet pipe lines corresponding groove respectively, spring (16) is had outside cavity, spring one end is connected with cavity, one end is connected with pull bar end, between valve plug and two surfaces of cavity inner wall sliding-contact, have and tiny gap, so move up and down in process at valve plug, the water of valve plug place cavity and valve plug groove can circulate, but normally can not circulate to the water of the inlet and outlet pipe lines by two grooves and impact.

One axostylus axostyle (20) of valve cavity extenal fixation, axostylus axostyle, through pull bar (17) end axis hole, moves up and down in process at valve plug, can prevent valve plug from rotating.

Valve plug in valve cavity, has and somely tinyly crosses aquaporin (30) up and down, it is characterized in that passage penetrates valve plug, and passage is symmetrical, be evenly distributed on around pitch brace.

Two groove structures of valve plug, size is the same, two groups of inlet channel scope overall processes are arrived at groove, by hydraulic pressure area equation, and be also equal with valve plug two parts superficial area of cavity inner wall sliding-contact beyond groove, namely groove structure, size is just the same, groove vicinity structure, size is symmetrical, uniformly, the a bit of two groups of inlet and outlet pipe lines in the outer valve plug both sides of valve, identical water inlet or outlet conduit same position are symmetrical, and same pipeline same position symmetric points with axis of symmetry line at same straight line or parallel, the water inlet area of two groups of inlet channels on cavity is equal, valve plug is identical by two inlet channel water pressures, so whole valve plug moves up and down the resistance that water that process can not be subject to two inlet and outlet pipe lines substantially produces valve plug.

When control valve pipeline (10) is intake, tiny on gap between valve plug and control valve cavity (15) and valve plug crosses aquaporin (30), and to make valve plug be up and down linker structure, valve plug top lacks pull bar (17) sectional area lifting surface area by water pressure area ratio bottom lifting surface area, and, water pressure suffered by valve plug upper surface and spring (16) maximum potential elastic force sum are still less than water pressure suffered by valve plug soffit, so after pipeline (10) water inlet, valve plug can move to cavity top end from bottom to top.

Control valve same group of inlet and outlet pipe lines can in same level, also can not in same level.

Accompanying drawing illustrates:

Fig. 1 is tank for excrement pan and by-pass valve control vertical direction cross-section structure sketch (valve two groups of inlet and outlet pipe lines are not in same level)

Fig. 2 be by-pass valve control two groups of inlet and outlet pipe lines when same level horizontal through by-pass valve control and pipeline cross-section structure sketch (Fig. 1, Fig. 2 same parts is consulted jointly)

Detailed description of the invention:

When closet is in idle inactive state, water tank cylinder barrel (4) inner carrier (5) is positioned at bottom cylinder barrel, pitch brace side is had to be full of the water with pressure in cylinder barrel, two water tank water intake main pipeline (1) valves (27) are closed, one radiator drain road (6) valve (8) is opened, and another radiator drain road (21) valve (8) is opened equally.

When closet is static, in control valve cavity, valve plug (15) and pull bar (17) link together, pull bar and valve plug are by spring (16) pulling force downwards, valve plug is positioned at cavity lowermost end, valve plug groove is positioned at below cavity two groups of inlet and outlet pipe lines, and two groups of inlet channels are so blocked by valve plug.

When people at one's leisure, two outlet conduit valve states change at once, valve (8) is closed, water inlet major trunk roads (1) valve (27) is opened, piston (5) below compression area is greater than top, piston moves up under hydraulic pressure effect, and mobile maximum position is that piston rod (3) all stretches out outside cylinder barrel.

After people leaves, pipeline valve state get back to again closet static time state, water inlet main pipeline (1) valve (27) is closed, outlet conduit (6) valve (8) is opened, outlet conduit (21) valve (8) is opened, and piston is now only by the hydraulic pressure of pipeline side above piston, and water under high pressure just promotes piston and moves down, water below piston is extruded by pipeline by piston, starts flushing and the preparation of carrying out closet.

The water in two radiator drain roads can distinguish arrival control valve two inlet channel (12 rapidly, 18), simultaneously, a water part for outlet conduit (6) can be passed through valve (8) at first and flow out, start rapidly ejection, control closet piston to decline, a part is by the inlet channel (10) of control valve, flow control valve (11) starts to arrive control valve cavity bottom, the water intake velocity that flow control valve can well control pipeline (10) to move up speed with control valve plug, start to move up by hydraulic pressure bottom valve plug, spring (16) is progressively elongated.

Before control valve valve plug rises to enough height, the water of control valve cavity two inlet channel (12,18) all can not flow out from respective outlet conduit (13,19), when valve plug is pushed into enough height by hydraulic pressure, when valve plug groove can cover cavity two groups of inlet and outlet pipe lines, control valve two outlet conduit can have water to discharge, and starts to carry out toilet stool washing work.

The water respectively by pipeline (12) and pipeline (18) is discharged by two water tanks, two water tanks can set different water yield, different flushing period as required, the water management closet piston of being discharged by pipeline (19) of a wherein water tank can be rotated, and by water yield or go out water speed difference, set the water that flowed out by pipeline (19) than pipeline (13) flow out comparatively Zao drained, and closet piston can lean on inertia to continue rotation a period of time.When pipeline (19) does not have water to discharge, control valve can't be affected, and the water that another water tank is discharged by pipeline (6) and pipeline (13) can continue toilet stool washing.

When the water of being discharged by pipeline (6) and pipeline (13) is drained, control valve valve plug lower end disappears by water pressure, and valve plug is by spring-return, and in control valve cavity, water is through slowly circulation, and valve plug gets back to cavity bottom.

Closet all working completes.
