Description
Technical field
The utility model relates to hitch folding control device technical field, specifically a kind of subway hitch pneumatic control
Module.
Background technique
In the prior art, when subway train controls coupler-uncoupling or even hangs, what is generallyd use is dcs, both
There is solenoid valve also to have Pneumatic valve, this results in many drawbacks.Various control elements dispersed placement on hitch uses between each other
Connector and piping connection, i.e. having vent line also has Electronic control cable in system, since hitch shape is special for installation
Space is very limited, this causes inconvenience to production assembly.Production efficiency is not only greatly reduced, but also makes to manufacture
Cost is high, and since control element is relatively at random, carries out very inconvenient when movement debugging.Due to the phase of subway vehicle
It closes configuration and differs more with high-speed rail or motor-car, the gas source cleanliness on vehicle is generally poor, and the impurity in pipeline is more, in hitch control
Tubulation road causes the operation troubles rate of pneumatic element higher also without arranging reasonable air filter, service life
It is difficult to reach design requirement.This distributed hitch control system once goes wrong, it is difficult to promptly and accurately judge failure simultaneously
And maintenance replacement is very troublesome, needs to dismantle a large amount of connector and pipeline, it is time-consuming and laborious that be unable to satisfy online vehicle in use quick
The requirement of maintenance support.Subway hitch is in exposed state, above-mentioned control system working environment is disliked due to lacking shutter protection
Bad, distributed AC servo system design easily injures destruction by outside exergy dissipation, is designed to that the structure of Compact robust is also imperative answers
With requiring.
Utility model content
The purpose of this utility model is to provide a kind of subway hitch Pneumatic control modules, are set for solving by integrated
Meter, the technical issues of flexibly control the opening and closing of hitch.
The technical solution adopted by the utility model to solve its technical problems is that: a kind of subway hitch Pneumatic control module,
Including packaging valve body and the Pneumatic valve A being mounted on packaging valve body, Pneumatic valve B, inline filter and noise reduction dust-proof device；Gas
It controls valve A and is equipped with A1 air inlet, the gas outlet A2 and the gas outlet A4, Pneumatic valve B is equipped with B1 air inlet, B4 air inlet and the gas outlet B2,
Pneumatic valve B is connected to by the gas outlet B2 with Pneumatic valve A.
Further, the Pneumatic valve A, Pneumatic valve B, inline filter and noise reduction dust-proof device and integrated valve body use plate
Formula connection.
Further, the Pneumatic valve A, Pneumatic valve B in hidden be mounted in manifold valve body.
The effect provided in utility model content is only the effect of embodiment, rather than whole effects that utility model is all
Fruit, have the following advantages that in above-mentioned technical proposal or the utility model has the advantages that
1, the utility model uses pure Pneumatic Control Technology, is designed by the inner passage of integrated valve body, makes each control member
A complete control loop is formed between part, volume essence is small, compact-sized；It does not need to access external controlling cable, installation side
Just, control is simple.
2, due to not needing fitting joint and connecting line using inner passage Integrated design, than tradition point
Cloth control system substantially increases production efficiency, effectively reduces manufacturing cost；And control element is all made of board-like connection,
It repairs simple to operate when replacement, so that previous heavy service work is become time saving, laborsaving, efficient, meet well
The requirement that train quickly ensures, this is that traditional product is unable to reach at all.
4, it is designed with inline filter in each inlet channel, gas source cleanliness has been effectively ensured, to drop significantly
The failure rate of low pneumatic element operation, improves its service life.
5, element is designed on application valve body using flush type, and surface greatly reduces component and pipe without projecting part
The probability that road is destroyed by external force strike in operation, and whole block structure is very sturdy and durable.

Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this
Utility model is described in detail.It should be noted that illustrated component is not drawn necessarily to scale in the accompanying drawings.The utility model
It is omitted to known assemblies and well-known technique description, to avoid the utility model is unnecessarily limiting.
As shown in Figures 1 to 4, a kind of subway hitch Pneumatic control module, including packaging valve body 1, Pneumatic valve A2, Pneumatic valve
B3, inline filter 4 and noise reduction dust-proof device 5, the Pneumatic valve A2, Pneumatic valve B3, inline filter 4 and noise reduction dust-proof device
5 use board-like connection with integrated valve body；It is hidden in Pneumatic valve A2, Pneumatic valve B3 are equal to be mounted in packaging valve body 1 (Pneumatic valve A2, gas
The surface indentation of valve B3 is controlled within 1 surface of integrated valve body).Pneumatic valve A2 and Pneumatic valve B3 is used to control the movement of hitch, interior
Embedded filter 4 is used for gas supply gas source filtering, and noise reduction dust-proof device 5 is used to reduce noise when system exhaust and stops external dust
Into.
The working principle of the utility model are as follows: hitch is in even extension state under normal circumstances, and A1 air inlet 6 supplies at this time,
The gas outlet A2 7 of Pneumatic valve A2 is supplied to hitch, it is made to keep connection status.When hitch needs uncoupling to operate, uncoupling gas source
It supplying simultaneously to B1 air inlet 8, B4 air inlet 9, the gas outlet B2 10 of Pneumatic valve B3 inputs gas control signal to Pneumatic valve A2 at this time,
Make Pneumatic valve A2 commutation action, and then the gas outlet A4 11 is supplied to hitch, disengages it from connection status.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, on the basis of technical solutions of the utility model, those skilled in the art do not need to pay creativeness
The various modifications or changes that can make of labour it is still within the protection scope of the present utility model.
