Thus affect car load line clear degree, affect braking performance of vehicle under serious conditions.
The Chinese utility model patent of Patent No. ZL200720311691.2 discloses a kind of controlled brake relay valve, should
Controlled brake relay valve is provided with filter screen at air inlet, is effectively reduced the impurity such as steam, dust and enters valve inner, carries
The high cleannes of car load pipeline.But owing at air inlet, passage is the least, the effective area of filter screen is the least, the most severe
Environment when using, it is more likely that there will be filter screen part or all block, causing air inlet stream unstable, thus cause system
The serious conditions such as dynamic time delay, brake force is not enough；And due to the narrow space between air inlet to filter screen, filter screen is when mounted
Assembly difficulty is the biggest.
Summary of the invention
The purpose of this utility model is that providing a kind of while impurity, does not interferes with air inlet in effective removal air inlet
Patency, it is ensured that follow-up system is reliably with a kind of Car Relay Valve of gas, and this one Car Relay Valve also has easy to assembly
Advantage.
For achieving the above object, this utility model adopts the following technical scheme that a kind of Car Relay Valve, including upper valve body and
Lower valve body, described lower valve body is provided with air inlet, gas outlet and valve body room；It is provided with servo between described lower valve body and upper valve body
Piston chamber, described valve body room connects with air inlet, and described valve body room connects with relay piston room；Described valve body indoor set
Having piston assembly, described piston assembly to include spring, spring base and leather cup, described leather cup is ringwise；Described spring base
Connected by spring with leather cup；Described valve body indoor are provided with filter screen, and described filter screen is tubular and piston assembly is wrapped in
In filter screen.
As preferably, between described filter screen and piston assembly, it is provided with limited step.
As preferably, described lower valve body also includes valve seat, under naturalness, leather cup under the action of the spring with valve base sealing
Contact.
As preferably, described upper valve body is provided with control mouth, is provided with two-way valve in described control mouth.
Use above technical scheme can obtain following beneficial effect:
1. filter screen being arranged on valve body indoor, air-flow enters valve body room through drainage screen, and filter screen can be effectively by dust-like
Grain thing filters, it is ensured that the cleannes in valve body；
2., relative to filter screen being arranged on the mode at air inlet, filter screen being arranged on valve body indoor, increasing filter screen
Effective area, reduces the risk of filter net jam；
3. filter screen is arranged on valve body indoor, be arranged at air inlet with by filter screen compared with, air inlet does not affect gas
The obstruction thing of body circulation, it is ensured that the patency of air-flow and stability in air inlet, it is ensured that the stability of relay valve work；
4. limited step is set between filter screen and piston assembly, can effectively prevent filter screen from deformation, dislocation etc. occurring
Situation:
5. the valve body interior space is relatively big, more convenient at valve body indoor location filter screen.
Accompanying drawing explanation
Illustrate for accompanying drawing below:
Fig. 1 is the structural representation of a kind of Car Relay Valve of the present embodiment；
Fig. 2 is the partial enlarged drawing of valve body room in a kind of Car Relay Valve of the present embodiment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Embodiment
A kind of Car Relay Valve as depicted, including upper valve body 1, lower valve body 8 and relay piston 11, described lower valve body
8 are provided with air inlet 3, gas outlet 9 and air vent 5；Described lower valve body 8 is provided with valve body room 7, described air inlet 3 and valve body room 7
Connection；Described valve body room 7 is provided with piston assembly, and described piston assembly includes spring 6, spring base and leather cup 13, described
Leather cup 13 is ringwise；Described spring base and leather cup 13 are connected by spring 6；Filter screen 4 it is provided with in described valve body room 7, described
Filter screen 4 be wrapped in inside filter screen 4 in tubular and by piston assembly；It is provided with limiting stand between described filter screen 4 and piston assembly
Rank 14；Described lower valve body 8 also includes valve seat 12, and under naturalness, leather cup 13 seals with valve seat 12 under spring 6 acts on and connects
Touch；It is provided with sealing ring between described valve seat 12 and lower valve body 8；Described upper valve body 1 is provided with control mouth 2, described control mouth 2
Inside it is provided with two-way valve.
The air inlet 3 of a kind of Car Relay Valve is connected with air pump, through the gas entrance valve body of overcompression, through valve body room 7,
Being positioned at filter screen 4 and the relay piston room 10 of valve body room 7, flow out from gas outlet 9, gas outlet 9 connects brake chamber, controls mouth 2 and connects
Brake valve, the output pressure of brake valve is as the control air pressure of relay valve；Give vent to anger containing the impurity such as steam and dust for air pump
Problem, piston assembly is trapped among in cylindrical filter screen 4, i.e. arranges filtration between piston assembly and air inlet 3 by this utility model
Device, effectively blocks the particulate matters such as dust and enters in valve body；Relative to filter screen 4 being arranged on the situation at air inlet 3, will
