Description
Technical field
The utility model relates to track traffic braking technology field, specifically, relates to a kind of rapid escape valve with guide in BP deliverance apparatus.
Background technique
Brake pipe deliverance apparatus (being called for short BP deliverance apparatus) is when rescue has the train of Brake pipe, need be Brake pipe pressure (BP pressure) by the braking electrical equipment instruction transformation of this car, control by the braking force of breakdown lorry, to reach the object controlling to be braked by breakdown lorry.
According to braking needs, the empty transfer valve of EPLA electricity in BP deliverance apparatus can realize being vented (small displacement), the output of control BP pressure.When BP pressure drained fast by needs, a kind of outlet valve is needed to discharge BP pressure with the discharge of first air guide fast from relief opening.
Model utility content
The technical problem solved
The purpose of this utility model is just to provide a kind of outlet valve can discharging Brake pipe pressure fast with guide.
Technological scheme
For achieving the above object, the utility model adopts following technological scheme:
With a guide's rapid escape valve, comprise valve body, piston assembly, valve seat, valve gap and spring; Described valve seat is pressed in valve body, described piston assembly is arranged in valve body, described valve assembly is arranged on valve seat, described piston assembly and valve assembly are by the chamber pre-control chamber of outlet valve, total wind chamber and exhaust cavity, described valve gap and spring are located on valve body, spring action, on piston assembly, provides initial sealing power.
Preferably, described pre-control chamber suction port is provided with filtrating equipment, can large granular impurity in filtered air.
Preferably, described valve body is provided with air flue, and supplied gas circulates, and is connected from different chambers.
Preferably, valve gap is connected with valve body by bolt.
Preferably, be provided with back-up ring and O type circle in described piston assembly, the sealing with different chamber can be realized.
Preferably, described pre-control chamber suction port is provided with choke, regulates charge flow rate.
Beneficial effect
Compared with prior art, the technological scheme that the utility model provides has following remarkable advantage:
(1) rapid escape valve of the present utility model is provided with pre-control chamber, total wind chamber and exhaust cavity, during use, can the total wind chamber of conducting and BP manage as required, also can according to the change of different chamber volume, realize piston assembly on move, realize Quick air-discharge, the pressure air of BP pipe drained fast;
(2) pre-control chamber of the present utility model is provided with choke, can regulate the pressure size in pre-control chamber (when needs are vented, the air inflow of suction port can be made to be less than the discharge capacity in pre-control chamber), pre-control chamber suction port is equipped with filtrating equipment and choke, improves the reliability and stability of outlet valve;
(3) structure of the present utility model is simple, easy to use, can realize exhaust fast, practical, is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model;
Fig. 2 is structure diagram of the present utility model.
Number in the figure illustrates: 1, piston assembly, 2, valve assembly, 3, back-up ring, 4, O type circle, 5, choke, 6, spring, 7, valve body, 8, valve gap, 9, pre-control chamber, 10, total wind chamber, 11, exhaust cavity, and 12 suction ports, 13, first air guide exhaust port, 14, BP pressure.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
As depicted in figs. 1 and 2, a kind of rapid escape valve with guide, comprises valve body 7, piston assembly 1, valve seat, valve gap 8 and spring 6; Described valve seat is pressed in valve body 7, described piston assembly 1 is arranged in valve body 7, described valve assembly 2 is arranged on valve seat, described piston assembly 1 and valve assembly 2 are by the chamber pre-control chamber 9 of outlet valve, total wind chamber 10 and exhaust cavity 11, described valve gap 8 and spring 6 are located on valve body 7, spring 6 acts on piston assembly 1, provides initial sealing power.
Described pre-control chamber 9 suction port is provided with filtrating equipment, can large granular impurity in filtered air.Described valve body 7 is provided with air flue, and supplied gas circulates, and is connected from different chambers.Valve gap is bolted on valve body.Be provided with back-up ring 3 and O type circle 4 in described piston assembly 1, the sealing with different chamber can be realized.The suction port in described pre-control chamber 9 is provided with choke 5, adjustable charge flow rate.
The utility model has conducting, Quick air-discharge two kinds of working staties.
Conducting: pressure air enters pre-control chamber 9 and total wind chamber 10, when pressure balance, achieves suction port 12 and the conducting of BP pipe.
Quick air-discharge: spring 6 acts on piston assembly 1, provides initial sealing power.Pressure air enters pre-control chamber 9 and total wind chamber 10, and air pressure reaches balance gradually.When receiving signal, solenoid valve can be vented rapidly, because pre-control chamber suction port has choke 5, can regulate the pressure size in pre-control chamber, make the air inflow of suction port be less than the first air guide discharge capacity in pre-control chamber.The air pressure in pre-control chamber 9 is less than the air pressure in total wind chamber 10, and piston assembly 1 moves up, and valve assembly 2 moves up thereupon, thus BP pipe is communicated with the relief opening (EX) of quick expulsion valve, and BP pressure 14 is drained rapidly.
