Abstract
The utility model provides a valve operating instrument, including handle, reset spring, lift arm, cross steel sheet, bolt, nut and transfer line, the handle on be fixed with reset spring, the lift arm upper end is connected with the handle is articulated, lift arm lower extreme and transfer line upper end fixed connection, it has four bar grooves to mill on the cross steel sheet, the middle part and the transfer line welded connection of cross steel sheet, bolt are located the bar inslot, the nut with the bolt fastening on the cross steel sheet, still have the bolt bayonet socket on the bolt. The utility model discloses simple structure, convenient to use can easily open and close large -scale valve, have reduced operating sequence, have alleviateed workman's intensity of labour.
Description
Technical field
The utility model relates to a kind of valve operational tool of pumped storage station.
Background technology
At present, operation opening/shutting valve can only go deep into operation after manually having dressed appliances for labor protection, specifically holds the operation of valve handle, has following defect: 1, operating process is loaded down with trivial details; When 2, there is emergency situation, corresponding valve cannot be turned off in time, affect the promptness of valve switch; 3, valve be in far or relatively rise from, manually cannot arrive.
Summary of the invention
The utility model is exactly a kind of valve operational tool being provided a kind of structure simple, easy to operate.
The technical solution of the utility model is: a kind of valve operational tool, comprise handle, return spring, lifting arm, cross steel plate, bolt, nut and transmission rod, described handle is fixed with return spring, lifting arm upper end and handle are articulated and connected, promote the lower end of arm to be fixedly connected with transmission rod upper end, cruciform steel plate is milled with four bar-shaped troughs, middle part and the transmission rod of cruciform steel plate are welded to connect, bolt is positioned at bar-shaped trough, nut will be bolted on cruciform steel plate, also with bolt bayonet socket on bolt.
Lifting arm described in the utility model is formed by connecting by brace section and straight bar section, and upper end and the handle of brace section are fixed, and straight bar section is become by more piece socket connection.
When the utility model works, adjusting bolt bayonet socket, to suitable diameter, by this tool card on valve disc, is had an effect by holding handle, and then drives transmission rod action, thus light opening/shutting valve.
This practical useful effect newly is: the utility model structure is simple, easy to use, it is possible to easily opens and closes large size valve, decreases schedule of operation, alleviates the labour intensity of workman.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
