Existing medium-sized pressure regulator valve (as Fig. 1, Fig. 2) has band 1-2 mouth gas-charging connection, has 22 mouthfuls, 23 mouthfuls, 4 mouthfuls and mounting hole.Its boundary dimension is 108mm * 90mm * 164mm, and the shortcoming of its existence is a complex structure, all needs special mounting point and mounting bracket during installation, is not easy to operation.When in braking system, using, the long rate of fault height that causes of, pipeline many owing to pipe joint.General plain edition valve body structure complexity is easy to generate the die casting defective, as pore, and crackle etc., and the housing gas leak phenomenon takes place easily, and often need secondary or three leak-stopping techniques, just can stop this phenomenon.Therefore also there is complex process on the manufacturing process, defective, the shortcoming that reject rate is higher occurs easily.
The model utility content
The purpose of this utility model provides a kind of pressure regulator valve, it can directly be installed on interface on the interface of gas receiver or other air brake pipings, and middle pipeline without other connects, and also need not fix by independent scaffold, more simple and fast is installed in realization, and pipeline is simplified.Can realize making braking system because pipe joint is many, pipeline is long and rate of fault that cause reduces.
In order to realize above-mentioned purpose of design, the scheme that the utility model adopts is as follows:
A kind of simple and easy off-load pressure regulator valve, its valve body is provided with suction port 1, air outlet 2 and relief opening 3, be formed with cavity A and cavity I in the described valve body, described cavity A is connected by filter screen B with described suction port 1, be provided with one-way valve D between described suction port 1 and the described air outlet 2, be provided with aperture E, diaphragm F, pressure spring H and air intake valve G successively between described air outlet 2 and the described cavity I.
Preferably, keep apart by exhaust pition J between the cavity A of described simple and easy off-load pressure regulator valve valve body and the described cavity I, the bottom of exhaust pition J is provided with drain tap K and spring L, and described cavity I, cavity A isolate by described drain tap K and described relief opening 3.
Preferably, the top of the pressure spring H of described simple and easy off-load pressure regulator valve is provided with and regulates bolt M.
The beneficial effects of the utility model are:
1. the utility model simple and easy off-load pressure regulator valve makes boundary dimension little owing to reduced opening (as Fig. 3) unnecessary on the structure, and is in light weight, thereby simplified brake line, alleviated the weight of car load;
2. the simple and easy off-load pressure regulator valve of the utility model can directly be installed on interface on the interface of gas receiver or other air brake pipings, and middle pipeline without other connects, and need not install and fix separately in addition.Make so more simple and fast is installed, pipeline obtains simplifying.Also make braking system because pipe joint is many, pipeline is long and rate of fault that cause reduces;
3. because simple and easy off-load pressure regulator valve structure becomes simply, make production process simplify, reduce the reject rate of producing;
4. cancelled inflation interface of the prior art, reduced component, thereby reduced the ratio that breaks down in the assembly pressure regulation, be not easy to take place gas leak phenomenon, the job failure rate reduces;
5. be applicable to all vehicles that adopt the gas braking, applied widely, penetration and promotion easily.

Embodiment
Below in conjunction with accompanying drawing content of the present utility model is described, following description only is exemplary and indicative, should any restriction not arranged to protection domain of the present utility model.
A kind of simple and easy off-load pressure regulator valve (as Fig. 4), its boundary dimension is: L * W * H:90mm * 56mm * 144mm, valve body is provided with suction port 1, air outlet 2 and relief opening 3, be formed with cavity A and cavity I in the valve body, described cavity A is connected by filter screen B with described suction port 1, be provided with one-way valve D between described suction port 1 and the described air outlet 2, be provided with aperture E, diaphragm F, pressure spring H and air intake valve G successively between described air outlet 2 and the described cavity I.
Keep apart by exhaust pition J between the cavity A of simple and easy off-load pressure regulator valve valve body of the present utility model and the described cavity I, the bottom of exhaust pition J is provided with drain tap K and spring L, pressure in cavity I reaches predetermined value, will promote exhaust pition J moves downward, described cavity I, cavity A isolate by drain tap K and relief opening 3, promote drain tap K when exhaust pition J moves downward, opening of drain tap K makes cavity I, cavity A be communicated with relief opening.
The top of the pressure spring H of simple and easy off-load pressure regulator valve of the present utility model is provided with regulates bolt M.Can regulate bolt M by turn, thereby regulate the precompression of pressure spring H, and then realize regulating required delivery pressure.
Simple and easy off-load pressure regulator valve of the present utility model has been cancelled the 1-2 mouth than common pressure regulator valve in the prior art (as Fig. 1, Fig. 2), and 22 mouthfuls, 23 mouthfuls, 4 mouthfuls and mounting hole.The 1-2 mouth of common pressure regulator valve was the inflation interface originally in the prior art, its objective is to give tyre inflation under the situation of air pressure deficiency, and this gas-charging connection seldom uses in practice, and a lot of users not use this gas-charging connection to inflate.The pressure regulator valve of not opening 22 mouthfuls, 23 mouthfuls, 4 mouthfuls in the market is also more universal, can not influence product pressure regulating performance and pressurized seal performance after cancelling these interfaces.
The working principle of off-load pressure regulation of the present utility model:
The pressurized air that comes from air compressor enters the A chamber by suction port 1, through filter screen B, is exported by air outlet 2 through one-way valve D again.A part of gas acts on respectively on diaphragm F and the air intake valve G through aperture E simultaneously, when the air pressure of air outlet 2 reaches the pressure of setting, air pressure promotes diaphragm F, pressure spring H opens air intake valve G, enters the I chamber, promote exhaust pition J, open drain tap K, the pressurized air in A chamber is discharged from relief opening 3 together with the water under the filter screen B upward filtration, impurity, make the air compressor of link pressure regulator valve be in unloaded state; Air pressure when air outlet 2 descends, and air intake valve G and drain tap K successively close, and at this moment air outlet 2 continues that output is arranged, and bolt M is regulated in turn, can obtain required delivery pressure.
Embodiment recited above is described preferred implementation of the present utility model; be not that the utility model scope is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in related domain make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
