Abstract
The invention provides a main transformer and radiator circulating pipeline valve locking device, relates to locking devices and aims to solve the problems of valve abrasion, non-circulation of transformer oil caused by locked valve after maintenance, valve oil injection accidents due to release of too high internal pressure of the main transformer caused by too high temperature of the main transformer, and power failure accidents caused by tripping of the main transformer switch. The locking device comprises a locking body and a padlock, wherein the locking body is composed of a left locking piece, a right locking piece, a valve locking and positioning opening and device lockholes. The valve locking device can protect the valve and the control pin and prolong the service lives of the valve and the control pin; and meanwhile, during maintenance, the valve is required to be closed for unlocking, and after maintenance, the valve is required to be opened for locking again, so that the device can remind workers of closing the valve during maintenance and opening the valve again after maintenance; the valve locking device is used for locking the main transformer and the radiator circulating pipeline valve.
Description
Technical field
The present invention relates to locking device.
Background technique
At present, along with the increase of main transformer maintenance business, main transformer and radiator circulating line take often to be opened valve and keeps in repair, and opens frequently and closes the loss that easily causes valve, causes the generation of accident, and forget buttoned-up valve open in the main transformer maintenance process of being everlasting when operator on duty and maintainer, cause transformer oil not circulate, main transformer excess Temperature, causes the excessive relief valve oil-spraying of main transformer internal pressure to occur, make main transformer switch tripping operation, cause power outage.
Summary of the invention
The present invention will solve the loss problem of valve, and do not open valve after maintenance, cause transformer oil not circulate, main transformer excess Temperature, cause the excessive relief valve oil-spraying of main transformer internal pressure to occur, make main transformer switch tripping operation, cause power outage, and a kind of main transformer and radiator circulating line valve locking device are provided.
A kind of main transformer and radiator circulating line valve locking device are by locking main body and padlock forms, locking main body is made up of left locking plate, right locking plate, locking valve positioning port and device lockhole, wherein, locking valve positioning port is arranged on the upper end of locking main body, left locking plate is positioned at the left side of locking valve positioning port, right locking plate is positioned at the right side of locking valve positioning port, the lower end of left locking plate and the lower end of right locking plate are respectively provided with a device lockhole, and padlock is locked in the device lockhole in locking main body.
The invention has the beneficial effects as follows: the invention provides a kind of main transformer and radiator circulating line valve locking device, because this device need be enclosed within on valve control pin, and the locking that locks, valve and control pin are all played a protective role, extend its working life; Simultaneously in the time of maintenance, need throttle down to unblank, overhaul complete, need open valve and again lock, therefore, this device can play reminds staff's throttle down and overhauled the effect of again opening valve in maintenance process, thereby avoid occurring because work mistake causes power outage, and simple, practical, convenient, be convenient to mounting or dismounting, a people can operate.
The present invention is used for locking main transformer and radiator circulating line valve.
