Abstract
The utility model discloses a kind of multi-functional relief fittings, comprise pressure regulation body and connector for being connected pressure regulator valve, described pressure regulation body has the inner chamber being communicated with described connector, in described inner chamber, be provided with piston, on described pressure regulation body, there is bar hole, on described piston, there is screw hole, described screw hole and bar hole correspondence, on described piston, be provided with lock and press screw, described lock presses screw to be connected through described bar hole and described screw hole.Owing to can passing through the effective water outlet length of Position Control bar hole of regulating piston, carry out the discharge pressure of auxiliary adjustment pressure regulator valve, bar hole plays the effect of pressure release simultaneously.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of multi-functional relief fittings.
Background technology
Jetting machine is to make high-pressure plunger pump generation water under high pressure rinse the machine of body surface by power set.It can be peeled off dirt, washes away, and reaches the object on cleaning of objects surface.Pressure regulator valve on jetting machine is provided with relief fittings, existing relief fittings function singleness.And pressure regulator valve is along with the increase of working time, its pressure oscillation regulating is larger, and default pressure and actual pressure are obviously different, cause pressure regulator valve to lose due effect.
Summary of the invention
The problem that the utility model exists for prior art proposes a kind of multi-functional relief fittings, and object is the stability of the pressure regulation that improves pressure regulator valve.
The utility model is achieved in that
A kind of multi-functional relief fittings, it is characterized in that, comprise pressure regulation body and connector for being connected pressure regulator valve, described pressure regulation body has the inner chamber being communicated with described connector, in described inner chamber, is provided with piston, on described pressure regulation body, has bar hole, on described piston, there is screw hole, described screw hole and bar hole correspondence, be provided with lock and press screw on described piston, described lock presses screw to be connected through described bar hole and described screw hole.
In the multi-functional relief fittings of above-mentioned one, between the diapire of described pressure regulation body and piston, have pressure spring, one end of described pressure spring is fixed on the diapire of described pressure regulation body, and the other end of described pressure spring is fixed on described piston.
In the multi-functional relief fittings of above-mentioned one, it is regular hexagon that described lock is pressed the nut cross section of screw.
The multi-functional relief fittings of one provided by the utility model, owing to can passing through the effective water outlet length of Position Control bar hole of regulating piston, carrys out the discharge pressure of auxiliary adjustment pressure regulator valve, and bar hole plays the effect of pressure release simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model relief fittings.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The present embodiment provides a kind of multi-functional relief fittings, as shown in Figure 1, comprises pressure regulation body 100 and connector.Connector is for being connected with the main body of pressure regulator valve, hollow and have opening.Pressure regulation body 100 is connected with connector, and pressure regulation body 100 has inner chamber, and one end of pressure regulation body 100 and connector are communicated with, other end sealing.In inner chamber, be provided with piston 110, piston 110 is cylinder and can in inner chamber, slides.On pressure regulation body 100, have bar hole 140, screw hole and bar hole 140 correspondences, be provided with lock and press screw 120 on piston 110, and lock presses screw 120 to be connected through described bar hole 140 and screw hole.
When pressure regulator valve is normally worked, piston 110, in the one end near connector, prevents that the water in pressure regulator valve from flowing out from bar hole 140, and now lock is pressed the inwall that withstands on tightly pressure regulation body 100 of screw 120, the activity of lock piston 110.In the time of needs pressure release, unclamp lock and press screw 120, to stir lock and press screw 120 to impel piston 110 to move, pressure regulator valve is by bar hole 140 and extraneous connection realizing pressure release.
In the time that pressure regulator valve is worked, the pressure in pressure regulator valve exceedes necessary pressure, and now, by regulating bar hole 140 effective lengths, controlling pressure regulator valve can be in the state work compared with low pressure.The effective length of bar hole 140 is the length of bar hole 140 water outlets.
Further, between the diapire of pressure regulation body 100 and piston 110, have pressure spring 130, one end of described pressure spring 130 is fixed on the diapire of described pressure regulation body 100, and the other end of described pressure spring 130 is fixed on described piston 110.The pressure oscillation regulating when pressure regulator valve is larger, when default pressure and actual pressure are obviously different, unclamp lock and presses screw 120, by the effect of pressure spring 130, makes the pressure in pressure regulator valve can be in comparatively stable state.
It is regular hexagon that lock is pressed the nut cross section of screw 120, is convenient to free-hand rotation, and can realizes forced locking by outer hexagonal spanner.
Should be understood that; the foregoing is only preferred embodiment of the present utility model; be not sufficient to limit the technical solution of the utility model; for those of ordinary skills; within spirit of the present utility model and principle; can be increased and decreased according to the above description, replaced, converted or be improved, and all these increases and decreases, replace, conversion or improve after technical scheme, all should belong to the protection domain of the utility model claims.
