Abstract
The utility model relates to a three-way valve for an industrial and mining locomotive, which comprises an upper cover plate, wherein the top end of the upper cover plate is equipped with a tear hole nut; a valve body is arranged below the upper cover plate; a lower cover plate is arranged below the valve body; a tear hole plunger, a compression plate, a piston, a plunger and a valve sleeve are sequentially arranged between the upper cover plate and the valve body; a tear hole spring is sleeved in the tear hole plunger; a tear hole adjustment screw is arranged in a spool; a one-way valve sleeve and a one-way valve plunger which are distributed perpendicularly to the valve sleeve are further sequentially arranged in the valve body; a one-way valve spring is sleeved in the one-way valve plunger; and a one-way valve nut which shares a same mandrel with the one-way valve spring is further arranged on the outer side face of the valve body. The three-way valve for the industrial and mining locomotive not only has a compact structure, but also has operation reliability and good security.
Description
Technical field
The utility model relates to a kind of three-way valve, relates in particular to a kind of industrial and mining locomotive and uses three-way valve.
Background technique
The decompression type braking system mainly is made up of with three-way valve, auxiliary reservoir, emergency valve, pressure regulator valve, selector valve brake valve, industrial and mining locomotive; When brake-cylinder pressure is lower than service braking pressure; Selector valve cuts out this master cylinder, and remaining pressure will be discharged with three-way valve from industrial and mining locomotive.
The model utility content
The technical problem that the utility model will solve is: the utility model provides a kind of industrial and mining locomotive to use three-way valve, and its compact structure operates reliably, and Security is good.
The utility model solves the technological scheme that its technical problem adopted: a kind of industrial and mining locomotive is used three-way valve; Has upper cover plate; The top of upper cover plate is equipped with tears hole nut, and the below of upper cover plate is equipped with valve body, and the below of valve body is equipped with lower cover plate; Be disposed with tears hole plunger, pressing plate, piston, spool, plunger and valve pocket between upper cover plate and the valve body; Be with tears hole spring in the plunger of tears hole, adjustment screw in tears hole is installed in the spool, unidirectional valve pocket and one-way valve plunger with the valve pocket vertical distribution also are installed in the valve body successively; Be arranged with check valve spring in the one-way valve plunger, the outer side surface of valve body also is equipped with the one-way valve nut with the check valve spring concentric shafts.
Further: be installed in the valve body and and process by copper material with the unidirectional valve pocket of valve pocket vertical distribution.
The beneficial effect of the utility model: the industrial and mining locomotive of the utility model is used the three-way valve compact structure, is used for diesel shunting locomotive and industrial and mining locomotive, operates reliably, and Security is good, mainly has following three advantages:
One, mitigation: the path that the supercharging of train pipe is linked up master cylinder and atmosphere simultaneously to the auxiliary reservoir inflation is carried out release of brake;
Two, braking action: the path of linking up auxiliary reservoir and master cylinder during the decompression of train pipe is carried out braking;
Three, neutral effect: the path that can cut off auxiliary reservoir and master cylinder when brake-cylinder pressure rises to certain value when train pipe stage decompression; The pressure of master cylinder can be risen in the stage, guarantee that simultaneously train pipe and auxiliary reservoir, auxiliary reservoir and master cylinder, master cylinder and atmosphere path all keep dissengaged positions.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
