The foregoing is only this utility model preferred embodiment, not thereby limit embodiment of the present utility model and
Protection domain.
It follows that the pump housing including jetting machine induction machine startup pressure relief device of a kind of preferred embodiment is described
Working method.
Continuing with shown in Figure 2, in a kind of preferred embodiment, when jetting machine is opened, the normal work of pump head 6
Pressure is 120bar, and the spring 71 of overflow valve 7 set recoil strength be equivalent to 140bar, so time overflow valve 7 head can
Blocking the second connector 62, overflow valve 7 is in closed mode.The pressure of spring 9 setting starting pressure relief device is equivalent to 20bar,
Far below the 120bar of the service pressure of pump head 6, pressure promotes valve body 2 to be butted on valve seat 8 backward so that the head of valve seat 8
Head in valve body connection hole 23 by valve body openings 22, blocked valve gap blind hole 11 with this by the head of valve seat 8, it is to avoid current from the beginning
Logical so that starting pressure relief device and be similarly in the state of closedown, final water is discharged by the first connector 61 completely.
Fig. 3 is a kind of schematic diagram including that jetting machine induction machine starts the vent position of the pump housing of pressure relief device,
Shown in Figure 3, in a kind of preferred embodiment, when jetting machine cuts out, overflow valve 7 becomes unique pressure release passage.
Pump head 6 pressure moment is increased beyond 140bar, the recoil strength set more than the spring 71 of overflow valve 7, promotes overflow backward with this
Valve 7 so that the valve rod 72 of overflow valve 7 touches travel switch, final machine power-off, water under high pressure by relief hole flow back into into
Water low-pressure area.Meanwhile, the pressure set owing to starting the spring 9 of pressure relief device is equivalent to 20bar, far below 140bar,
Therefore start pressure relief device and be in the state of closedown.
Fig. 4 is a kind of schematic diagram including that jetting machine induction machine starts the pressurize position of the pump housing of pressure relief device,
Shown in Figure 4, in a kind of preferred embodiment, jetting machine power-off because valve rod 72 touches travel switch, but motor
Under effect of inertia, need a bit of time of remaining in operation, more slowly stop.The internal pressure of pump head 6 is slowly reduced by 140bar,
The spool 73 of overflow valve 7 slowly falls after rise under the effect of spring 71, and the head of overflow valve 7 moves closer to the second connector
62.Although valve rod 73 slowly falls after rise, but is butted on travel switch so that machine is still in off-position.When in pump head 6
During portion's pressure as little as about 25-30bar, overflow valve 7 pressure at two ends balances, i.e. the pressure of spring 71 generation and the inside of pump head 6
The pressure of water under high pressure is equal, therefore overflow valve 7 keeps balance, keeps the state of pressurize.Meanwhile, owing to starting pressure relief device
The pressure that spring 9 sets is equivalent to 20bar, less than 25-30bar, therefore starts pressure relief device and is in the state of closedown.
When Fig. 5 is the pressurize of a kind of pump housing including jetting machine induction machine startup pressure relief device, internal leakage is restarted
The schematic diagram of instantaneous position, shown in Figure 5, in a kind of preferred embodiment, jetting machine is closed, if machine
Device is internal produces minor leakage, then the internal pressure of pump head 6 can be gradually lowered, and comparatively speaking, the spring 71 of overflow valve 7 promotes valve
Core 73 slowly falls after rise, until the head of overflow valve 7 is butted on the second connector 62, now the internal pressure of pump head 6 is less than 20bar,
For about 16-18bar.Owing to the head of overflow valve 7 is butted on the second connector 62, valve rod 72 departs from travel switch, causes machine
It is re-energised startup.The pressure set owing to starting the spring 9 of pressure relief device is equivalent to 20bar, more than the internal pressure of pump head 6
16-18bar, spring 9 promotes forward valve body 2 so that the valve body openings 22 of valve body 2 departs from the head of valve seat 8, makes place with this
The internal pressure of the pump head 6 in higher-pressure region by valve gap through hole 12, valve gap blind hole 11, valve body connection hole 23 and valve body openings 22 with
Being in the internal pressure connection of the 3rd connector 63 of low-pressure area, now the internal pressure of pump head 6 only has intake pressure.Due to machine
The electric motor starting moment that device is re-energised startup generation is little, but is because higher-pressure region and is connected with low-pressure area, and machine forms one
Interior recurrent state, water unresisted row to low-pressure area, can effectively ensure that motor can operate smoothly in the least, until internal pressure
Little by little raise.When pressure rises to more than 20bar, starting pressure relief device and be again in the state of closedown, machine reaches normal
Duty.
Fig. 6 is a kind of schematic diagram including that jetting machine induction machine starts the self-priming position of the pump housing of pressure relief device,
Shown in Figure 6, in a kind of preferred embodiment, when not having tap water in the pump housing 6, the pump housing 6 can as suction pump certainly
Be about to water suck be operated.Now start pressure relief device under the effect of spring 9 by the 2nd O RunddichtringO 4 of valve gap 1 and the
The endoporus conical surface of three connectors 63 is in close contact, with this by completely separated to higher-pressure region and low-pressure area, within during motor rotation sky
Gas constantly discharges, so that the pump housing 6 is internally formed vacuum, the water in outside bucket is under atmospheric pressure pressed in the pump housing 6
Portion.When the pump housing 6 stable operation, start pressure relief device and promote movement the most backward, until valve body connection hole 23 contacts valve
The head of seat 8, is cooperatively formed sealing by the taper surface of an O RunddichtringO 3 and the head of valve seat 8, blocks up with the head of this valve seat 8
Live valve gap blind hole 11, enter normal operation position, shown in Figure 2.
The foregoing is only this utility model preferred embodiment, not thereby limit embodiment of the present utility model and
Protection domain, to those skilled in the art, it should in can appreciate that all utilization this utility model description and diagram
Equivalent done by appearance and the scheme obtained by obvious change, all should be included in protection model of the present utility model
In enclosing.
