Abstract
The angle cock locking device is a valve locking device, especially for locking angle cocks used in railway locomotive and vehicle, and consists of valve body, valve core and locking mechanism, the locking mechanism is set on the valve core and communicated with the air pressure channel in the valve core, when the air pressure in the air pressure channel reaches the preset value, the locking mechanism locks the angle cock in open state, so as to ensure the running safety of locomotive. The utility model has the advantages of simple structure and reasonable design, use with the dog-ear cock cooperation of current railway locomotive, vehicle, reform transform simple to operate.
Description
The utility model belongs to the valve locking device, but what relate generally to is the angle cock of a kind of locking railway locomotive, vehicle.
The angle cock that existing railway locomotive, vehicle use, mainly constitute by valve body, spool, when spool position is in 0 when spending, angle cock is a closed condition, and when spool position is in 90 when spending, angle cock is opening state, because it does not have locking device, locomotive, vehicle angle cock under steam are easy to be closed by improper, thereby cause locomotive brake malfunctioning, even great train operation accident takes place.At present, also there is the angle cock of pair railway locomotive, vehicle to propose the locking measure, as the patent No.: " 88213438.3 " " safe angle cock ", its locking mechanism is arranged on the valve body, because its actuating unit exposes, destroyed artificially easily, and with the supporting use of existing angle cock, its processing technology complexity is difficult for transforming and implements.
The purpose of this utility model promptly produces thus, but the angle cock locking device that provides a kind of safety locking to be opening state, its locking device is arranged on valve core inside, and actuating unit is difficult for finding, thereby guaranteed the safety traffic of railway locomotive, vehicle effectively.
The utility model also is applicable to the valve locking in other field.
For achieving the above object, the utility model is achieved through the following technical solutions, and it mainly is made of valve body, spool, locking mechanism, is drilled with a hole on the spool, locking mechanism is arranged in its hole, and it is made of piston cylinder, piston, propelling rod, retracing spring, locking hole.Piston/cylinder one end and spool are fixed, the other end stretches in the spool, and communicate with the pressure channel in the spool, piston is arranged on an end that communicates with pressure channel in the piston cylinder, regulate the fixed position by dowel bolt, propelling rod is fixed on the piston, is with retracing spring on it, its coincide corresponding with the locking hole on being arranged on valve body.
The utility model is reasonable in design, and is simple in structure, very easily promotes realization with existing railway locomotive, the supporting use of vehicle, because its locking mechanism is arranged on valve inner, its actuating unit is difficult for being found, thereby has improved its safe reliability.
The utility model has following accompanying drawing.
Accompanying drawing is the utility model structural representation.
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure: the utility model is mainly by spool 1, valve body 2, pressure channel 3, piston cylinder 4, retracing spring 6, propelling rod 7, piston 8, dowel bolt 9, locking hole 5 constitutes, have a hole on the spool 1, piston cylinder 4 is arranged in the hole, the one end is a undergauge, piston cylinder 4 undergauges, one end and spool 1 are fixing, pressure channel 3 in the other end and the spool 1 communicates, piston 8 is arranged on an end that communicates with pressure channel 3 in the piston cylinder 4, by dowel bolt 9 secured adjusted, propelling rod 7 is fixedly connected with piston 8, be with retracing spring 6 on it, valve body 2 is provided with the locking hole 5 that is used for propelling rod 7 lockings.Working process of the present utility model is as follows: when the air pressure of the pressure channel on locomotive, the vehicle reaches certain value, when being pressure by air pressure greater than the strength of spring, piston is under the effect of air pressure, the drive propelling rod travels forward, locking hole locking on propelling rod front end and the valve body, thus realization is to the locking of angle cock; When not needing locking, need only make the strength of the interior air pressure of pressure channel less than spring, piston drives propelling rod and moves backward under the effect of retracing spring, and the separating lock closed pore is realized the angle cock release.
