Abstract
The utility model discloses a valve locking structure, which comprises an upper valve pulling rod arm and a lower valve pulling rod arm. The upper valve pulling rod arm and the lower valve pulling rod arm can drive a valve of a switch cabinet to open and close, the side faces of the valve pulling rod arms are provided with a valve pulling rod baffle which can block the valve pulling rod arms, and a rotary valve driving arm is arranged in front of the valve pulling rod arms and in a movement position in front of the valve pulling rod arms. The utility model has a reasonable structure. The two valve pulling rod arms can drive the valve of the switch cabinet to open. However, since the valve pulling rod arms under the natural condition are blocked by the valve pulling rod baffles, the valve pulling rod arms can move. The valve pulling rod arms can not move until the valve driving arm is touched by the circuit breaker trolley. Therefore, the valve can not be opened until the circuit breaker is started, thereby ensuring the safety of the personnel.
Description
Technical field:
The utility model relates to a kind of switchboard valve closedown structure.
Background technology:
Existing switchboard valve lacks blocking mechanism, has hidden danger in the use.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can guarantee the valve closedown structure of the practical safety of valve.
Technical solution of the present utility model is:
A kind of valve closedown structure, it is characterized in that: comprise driving the tie rod arm of valve up and down that the switchboard valve opens and closes, the side of valve tie rod arm is provided with the valve pull bar baffle plate that the valve tie rod arm is blocked, and is provided with rotatable in the place ahead of valve tie rod arm and is positioned at valve master arm on the movement position of valve tie rod arm the place ahead.
The utility model is rational in infrastructure, two valve tie rod arms, it move (drive the switchboard valve and open, but under the nature because to be blocked the valve tie rod arm by the active pull rod baffle plate be irremovable, only after movable master arm is bumped by circuit breaker cart, could move.This structure makes only could open valve after line breaker enters, guaranteed safety of persons.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of valve closedown structure, comprise and drive the tie rod arm of valve up and down 1,2 that the switchboard valve opens and closes, the side of valve tie rod arm is provided with the valve pull bar baffle plate 3 that the valve tie rod arm is blocked, and is provided with rotatable in the place ahead of valve tie rod arm and is positioned at valve master arm 4 on the movement position of valve tie rod arm the place ahead.
