Abstract
The utility model discloses a multifunctional automatic pressure relief valve which comprises a pressure adjusting wheel, a plunger piston, a pressure adjusting spring, a valve body, a valve core and a valve seat. The valve seat is matched and installed with the valve body; the valve core is installed in the valve body, on the valve seat; the pressure adjusting spring is installed in the valve body, on the valve core; the plunger piston is installed in the pressure adjusting wheel which is matched and connected with the valve body through screw threads; and the plunger piston props against the pressure adjusting spring. When the automatic pressure relief valve closes, the valve core seals the liquid discharge hole; the lowest part of the liquid discharge hole is spaced at a distance D with the sealing structure of the valve core, and the distance D is 5mm to 15mm. The multifunctional automatic pressure relief valve overcomes the disadvantage that at present the pressure adjusting valve and the automatic pressure relief valve only have pressure adjusting and pressure reliving functions and do not have the pressure stabilizing function. The multifunctional automatic pressure relief valve has the advantages of simple structure, convenient maintenance, high jet efficiency and good jet performance.
Description
Technical field the utility model relates to a kind of multi-functional automatic relief valve, belongs to hydraulic system pressure regulating valve product technical field.
The general pressure regulator valve that background technique is used at present has only voltage regulation function, does not have voltage stabilizing and pressure relief, and exactly when closing high pressure valve, the pressure of pump can be higher than working pressure, and dynamic load is increased the weight of, and obviously shorten the working life of power and liquid pump.
General automatic relief valve, be to utilize the safety check active force of closing highly pressurised liquid to promote pressure regulating valve, play the release effect, the shortcoming of this pressure-relief valve is that the pressure of high-voltage tube and injecting-unit is higher than working pressure equally, easily accelerate the damage of high-voltage tube and injecting-unit, another shortcoming of this valve is that closure of check ring sternly can not leak when liquid has impurity, pressure meeting take-off this moment like this can be bigger to liquid pump and dynamic effect.
Summary of the invention the utility model provides a kind of multi-functional automatic relief valve of novelty, adopts differential off-load structure, realizes the purpose of automatic pressure-relieving and voltage stabilizing.
The technical solution adopted in the utility model is:
A kind of multi-functional automatic relief valve, comprise: pressure adjusting roller, plunger, pressure adjusting spring, valve body, spool, valve seat, valve seat cooperates installation with valve body, spool is installed in the valve body and is positioned on the valve seat, pressure adjusting spring is installed in the valve body and is positioned on the spool, plunger is installed in the pressure adjusting roller, pressure adjusting roller is threaded with valve body and cooperates, plunger roof pressure pressure adjusting spring, spool closed leakage opening when automatic relief valve was closed, between the minimum position of leakage opening and the sealing configuration of spool a distance D is arranged, the length of distance D should be 5 to 15 millimeters.
Spool match with valve seat the sealing the end be cone structure.
Spool match with valve seat the sealing the end can also be spherical structure.
Spool match with valve seat the sealing the end can also be plane-shaped structure.
Between plunger and valve body, be provided with seal ring A, between valve body and valve seat, be provided with seal ring B.
The utility model beneficial effect is:
Owing to adopted multi-functional automatic relief valve of the present utility model, overcome that present pressure regulator valve and automatic relief valve have only pressure regulation and pressure relief and the shortcoming that do not have voltage stabilizing function, multi-functional automatic relief valve of the present utility model has simple in structure, use easy to maintenance, the ejection efficiency height, the characteristics that jet performance is good.

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3.
Multi-functional automatic relief valve, by: pressure adjusting roller 1, plunger 2, seal ring A3, pressure adjusting spring 4, valve body 5, spool 6, valve seat 7, seal ring B8 are formed.
A kind of multi-functional automatic relief valve, comprise: pressure adjusting roller 1, plunger 2, pressure adjusting spring 4, valve body 5, spool 6, valve seat 7, valve seat 7 cooperates installation with valve body 5, spool 6 is installed in the valve body 5 and is positioned on the valve seat 7, pressure adjusting spring 4 is installed in the valve body 5 and is positioned on the spool 6, plunger 2 is installed in the pressure adjusting roller 1, pressure adjusting roller 1 is threaded with valve body 5 and cooperates, plunger 2 roof pressure pressure adjusting springs 4, spool 6 closed leakage opening 9 when automatic relief valve was closed, between the minimum position of leakage opening 9 and the sealing configuration of spool 6 distance D is arranged, the length of distance D should be 5 to 15 millimeters.
Spool 6 match with valve seat 7 sealing the end be cone structure.
Spool 6 match with valve seat 7 sealing the end can also be spherical structure.
Spool 6 match with valve seat 7 sealing the end can also be plane-shaped structure.
Between plunger 2 and valve body 5, be provided with seal ring A3, between valve body 5 and valve seat 7, be provided with seal ring B8.
Pump is when normal operation, most of liquid is from nozzle or other operation area diffluence, when needs are set certain pressure, in new adjustment pressure adjusting roller 1 pressure range of setting up, plunger 2 is moved down, compressing pressure adjusting spring 4 under the effect of spring force, is pressed on the valve seat 7 spool 6, active force works in the valve seat orifice of valve seat 7 and area that spool 6 contacts, when the working pressure of pump surpassed the pressure of being set up, liquid promoted spool 6 and moves up, and spool 6 is opened, release unnecessary pressured fluid, and be expelled back into liquid sucting port by leakage opening 9 liquid return holes by the space between spool 6 and the valve body 5, when liquid pump pressure during less than the pressure set up, spool 6 is toward moving down, close valve seat 7 once more, be throttle down, in the throttle down process, liquid is storing certain energy between spool 6 and valve seat 7, promptly play pressure stabilization function, play buffer function again, reduce the bump between spool 6 and the valve seat 7, reduce noise.
When the closing liquid high-pressure outlet, the liquid of process pump will all flow to liquid sucting port by pressure regulator valve, this moment, spool 6 can't be released fully with the space of valve body 5, liquid can make spool 6 continue up to push away, the spool 6 and the leakage opening 9 of valve body 5 are opened, could release fully, at this moment pressure area is by the valve seat orifice enlarged areas of original valve seat 7 external diameter to spool 6, area obviously becomes big under same spring force effect, the pressure of liquid is obviously reduced, thereby play automatic decompression, promptly reduced the load of power, play energy-conserving action, can improve the working life of pump and high-voltage tube again.
The multi-functional automatic relief valve of the utility model is applicable to fields such as industry, cultural control, environment disinfected.
Working medium is oil, water or mobile liquid.
