Description
Technical field
The present invention relates to a kind of brake, more particularly to a kind of wagon control brake.
Background technology
Car Relay Valve is for shortening the brake reaction time manipulated in gas circuit, playing the work of fast aeration and Rapid degassing
With.Mainly there are two kinds of situations in current relay valve：A kind of plain edition relay valve, plain edition relay valve in carload,
In braking procedure, braking is more rough, not soft, serious abrasion is caused to tire and brake drum, although solving relay valve
Sensitivity problem when automobile heavy-load is braked, but shoe brake is damaged too big.Another kind is dual-active plunger type brake valve, dual-active
Plunger type brake valve is in automobile zero load, and in braking procedure, braking is more soft, but when automobile is in heavy duty, relay valve is past
It is past the drawbacks of piston is ineffective occur.
China Patent Publication No. CN 201494431U, publication date are on June 2nd, 2010, entitled " Car Relay Valve "
A kind of Car Relay Valve is disclosed in scheme, it is by servo valve body, relay valve bonnet, piston, fixed seat, intake valve sliding bar

Part one end offsets with seal lip, and the other end is by setting the first spring base and the upper casing body phase of the first spring and relay valve body
Support, and described sealing sliding part can be slided by pressure on described spring base, bottom chamber by set piston by its
Separately upper lower chamber, sets offseting for second spring seat and second spring and described seal lip on described piston, and
Piston upper center is provided with protruding block, and protruding block can be risen through seal lip by piston and be offseted with sealing sliding part,
Its upper chamber is set to be connected with the upper chamber of lower chambers, described upper chamber is connected with connecing the gas outlet of brake chamber.
As a further improvement, described two-way valve body includes housing and its valve element, described housing cavity both ends difference
Gas port and control mouth are deposited in setting, and middle part sets and deposits air pipe and control piper, and described deposits air pipe and described upper chamber's phase
Connection, described control piper are connected with the lower chamber of described lower chambers, and described valve element is placed in housing cavity, and unidirectionally
Control deposits gas port and deposits the path of air pipe or control mouth and control piper.
As a further improvement, it is described deposit gas port and deposit check valve is set between air pipe.
As a further improvement, described seal lip is by setting snap ring and clamping rings to be fixed on centre gangway mouth.
As a further improvement, multiple blow vents are set on the periphery of described clamping rings.
Its is simple in construction by the present invention, easy to assembly, securely and reliably, service life length, both can guarantee that automobile in zero load
Mildness, and can ensure that automobile has enough severities of braking in heavy duty.
