Abstract
The utility model discloses an improved invention of a mini-type multipurpose emergency relay valve, and the emergency relay valve comprises a valve body as well as an air supply joint (1), air reservoir joints (1-2) and output ports communicated with a brake chamber which are arranged on the valve body, and is characterized in that the number of the output ports (2), (2`) communicated with the brake chamber is two. The average size of length, width and height of the existing emergency relay valve is over 140mm, and the average size of length, width and height of the mini-type multipurpose emergency relay valve is only 92.5mm, thereby greatly saving the raw material and reducing the production cost.
Description
Technical field: what the utility model was related is a kind of braking that is used to control trailer or superimposed trailer ABS relay valve, particularly be for the improvement of output port number on relay valve invention.
Background technology: in the prior art, the emergency relay valve that cooperates the ABS relay valve to use on vehicle all is at least three delivery ports, and when entrucking, must block up two or more delivery ports, as long as staying a delivery port just can, and existing relay valve volume is huge, installs cumbersomely, and work efficiency is low, and raw materials consumption is excessive, so cost is high always.
Summary of the invention: in view of the deficiency that exists in the background technology, the technical matters that the utility model solved is in order to provide a kind of reasonable in design, simple in structure, to increase work efficiency, and can reduce a kind of micro-multi-purpose emergency relay valve of manufacturing cost.To achieve these goals, the utility model adopts following technological means to realize: this kind micro-multi-purpose emergency relay valve, include valve body, on described valve body, be provided with gas source interface, air receiver interface and the delivery port connected with compressed air brake cylinder, it is characterized in that described delivery port is two.
As preferably, described valve body delivery port position all is fitted with jointing.
The utility model compared with prior art has following advantage:
1, economical, A, existing emergency relay valve of joining the ABS relay valve all are at least three delivery ports, just must block up two or more delivery ports during entrucking, and this micro-multi-purpose emergency relay valve can design a delivery port, what two delivery ports were perhaps arranged blocks up a delivery port in use, and entrucking has just improved work efficiency like this.
The high average-size of B, existing emergency relay valve length and width is more than 140MM, and the high average-size of the length and width of this micro-multi-purpose emergency relay valve has only 92.5MM, and this will save raw MAT'L greatly, and productive costs reduces.
2, this micro-multi-purpose emergency relay valve also can design two delivery ports, and in the time of on being used in general trailer pipeline, can two delivery ports all open-minded, the compressed air brake cylinder import that connects back axle simultaneously just can.
3, existing emergency relay valve all is by special-purpose adapter plate, fixedly realizes installing with screw bolt and nut again; Or directly install with bolt and nut by the mounting hole of design on valve body.These two kinds of installations are difficulty relatively, and all to install by bolt and nut, the tapped bore of this micro-multi-purpose emergency relay valve by delivery port directly is connected the realization installation with a joint with air receiver on the trailer, because its volume is little, in light weight, joint has the sufficient intensity carrying, have advantages such as easy for installation, saving set-up time like this.
Description of drawings: the utility model has following accompanying drawing:
Fig. 1 is the utility model inner structure front view;
Fig. 2 is the utility model inner structure lateral plan.
The specific embodiment: relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however accompanying drawing is only for reference and explanation, is not to be used for the utility model is limited.
Seeing also Fig. 1 and Fig. 2, the utility model provides the structure of micro-multi-purpose emergency relay valve, the detail of this structure belongs to known technology, here just do not specifically describe, the utility model includes valve body, is provided with gas source interface 1 on described valve body, air receiver interface 1-2 and the delivery port connected with compressed air brake cylinder, and described delivery port 2,2` have two.Two delivery ports 2,2` cooperate glancing impact to stop up one of them delivery port with the ABS relay valve, so also just equal to have only a delivery port 2.In the time of on being used in general trailer pipeline, can two delivery port 2,2` all open-minded, and connect the compressed air brake cylinder of back axle simultaneously.Described valve body delivery port position all is fitted with the jointing (not shown).
The utility model cooperates glancing impact with the ABS relay valve, one of them hole of emergency relay valve that two delivery ports 2,2` are arranged is stopped up with plug 5: pressure gas enters gas source interface 1, by annular groove e, then enter the trailer air receiver for 1-2 mouthfuls through the air receiver interface of associating, simultaneously, through air intake valve h, from 4 mouthfuls of delivery port 2 to ABS relay valves, like this, just enter compressed air brake cylinder from the air pressure of 1 mouthful of ABS relay valve, thereby make the car brakeing (not shown); Also have, the pressure gas from supply line overcomes spring force at the cavity C build-up pressure when pressure reaches certain pressure, the second piston f is moved downward, this moment, drain tap b opened, and delivery port 2 and exhausr port 3 are connected like this, at this moment the air pressure of 4 mouthfuls of ABS relay valves through 2 mouthfuls from exhausr port 3 emptyings.The air pressure of compressed air brake cylinder is from ABS relay valve exhausr port exhaust to atmosphere, and vehicle can travel.
When service brake, pressure gas enters chamber A through brake activation valve from mouth 4, act on the top of first piston a, move downward, close drain tap b, open air intake valve h, air pressure from the trailer air receiver passes through 1-2 mouthfuls of chamber B that flow through of air receiver interface like this, arrive 4 mouthfuls of ABS relay valves from delivery port 2, make air pressure enter compressed air brake cylinder, realize braking from 1 mouthful of ABS relay valve.During brake off, the emptying of chamber A air pressure, the gas pressure of chamber B is below first piston a like this, make first piston a get back to its top, air intake valve h closes, and drain tap B opens, and the air pressure that the ABS relay valve is 4 mouthfuls is 3 mouthfuls of emptyings of valve from then on, the air pressure of compressed air brake cylinder is from ABS relay valve exhausr port exhaust to atmosphere, vehicle brake off.
During the trailer autobrake: when trailer does not connect or supply air line when fracture, gas source interface 1 emptying, cavity C pressure reduces, the power of spring g and air receiver interface 1-2 gas pressures make the second piston f upward movement in the power of the second piston f, close drain tap b like this, along with the second piston f upward movement.Air intake valve h opens, and the gas in the trailer air receiver flows into 4 mouthfuls of ABS relay valves through delivery port 2 like this, makes the ABS relay valve enter compressed air brake cylinder from 1 mouthful air pressure of trailer air tank, and vehicle is realized autobrake.
The utility model carries out glancing impact with general trailer, and principle of work is the same, and just delivery port 2 and 2` connect work simultaneously.And delivery port 2 and 2` directly connect compressed air brake cylinder.
