Problems solved by technology

Most of the existing valve driving devices are in the state of free switch, and any person can switch and adjust at will, unintentionally or even intentionally changing the normal use state of the valve, which will cause waste of water, oil, gas and other resources
The hand wheel or copper precious parts of the valve can be easily removed by using ordinary wrench and other tools. In severe cases, the pipeline will lead to major safety accidents
In particular, urban water supply and management departments have always lacked effective management methods for some units or individuals to use water without restraint, refuse to pay water fees, leak water, or even destroy pipeline valves.

Embodiment

[0016] Such as figure 1 As shown, the safety lock control drive device provided by the present invention includes a drive rod 1 , a wrench 2 , a lock ring 3 , a padlock 4 , a bolt 6 , a casing 7 , and a shield 9 . The drive rod 1 is protected inside by the casing 7 and the shield 9, and only a section of the upper end is exposed. The shield 9 is cylindrical, covered on the casing 7 and fixed with bolts 6 , and a locking ring 3 is arranged on the same side of the bolts 6 . The wrench 2 is L-shaped and has a locking port 10, a locking ring port 8 and an operating port 5. One side of the locking port 10 and the locking ring port 8 is a bevel, and the gap with the driving rod 1 and the locking ring 3 is small when locking, and there is no interference when the wrench is assembled or disassembled.

[0017] Such as figure 1 As shown, in the safety locking state, the locking port 10 of the wrench 2 is set on the exposed section of the driving rod 1, so that the driving rod 1 is lo...

Abstract

The invention relates to a safety lock control drive device, comprising a driving rod, a wrench, a lock ring, a padlock, a bolt, a protection cylinder and a shield. The protection cylinder and the shield are successively provided outside the driving rod; the driving rod is protected in the protection cylinder and the shield with the upper exposed end connected with the wrench; the bolt is arranged on the shield to fix the shield onto the protection cylinder; the lock ring and the bolt are arranged at same side of the shield, and the lockpad is disposed on the lock ring. Compared with the prior arts, the invention solves the problems of valve random switch and parts stolen just utilizing a wrench, and has the advantage of a simple and compact structure.

Description

technical field [0001] The invention relates to a valve drive device, in particular to a safety lock control drive device. Background technique [0002] Valves are important control elements in pipelines for water, oil, and gas. Most of the existing valve driving devices are in the state of free switch, and anyone can switch and adjust at will. Unintentionally or even intentionally changing the normal use state of the valve will cause waste of water, oil, gas and other resources. The hand wheel or copper precious parts of the valve can be easily removed by using ordinary wrench and other tools. In severe cases, the pipeline will cause major safety accidents. In particular, urban water supply and management departments have always lacked effective management methods for some units or individuals to use excessive water, refuse to pay water fees, leak water, or even destroy pipeline valves. Contents of the invention [0003] The object of the present invention is to provide...
