Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] Such as figure 1 As shown, a double anti-theft gate valve includes a valve body, a valve stem and a valve cover 1, the valve stem includes an active valve stem 9 and a driven valve stem 4, and a bushing is provided between the active valve stem 9 and the valve cover 1 10. There is a sealing sleeve 2 between the driven valve stem 4 and the valve cover 1, and a spring 6 is arranged in the hole of the driven valve stem 4. The spring 6 is connected with the...

Abstract

The invention provides a dual-thievery-prevention sluice valve. The dual-thievery-prevention sluice valve solves the problem that in the prior art, a sluice valve can be opened easily by non-professionals. The dual-thievery-prevention sluice valve comprises a valve body, valve rods and a valve deck. The valve rods comprise a drive valve rod and a driven valve rod. A supplement core is arranged between the drive valve rod and the valve deck. A seal sleeve is arranged between the driven valve rod and the valve deck. A spring is arranged in a hole of the driven valve rod. The spring is connected with a flat key. The flat key is connected with a magnet. A locating hole is formed in the drive valve rod. The upper portion of the drive valve rod is a pentagonal prism or a polygon prism. A locating column is arranged below the flat key. The locating column is sleeved with the spring. In the conventional state, the spring is in the compressed state, the spring exerts force upwards so that the flat key can be separated from the driven valve rod, when the drive valve rod is rotated at the moment, the driven valve rod keeps still, and therefore the state of the sluice valve cannot be adjusted. Only professionals can enable the drive valve rod to drive the driven valve rod to rotate when holding a professional hand wheel, and therefore it is avoided that a lawbreaker opens the sluice valve at will.

Description

technical field [0001] The invention relates to a gate valve, in particular to a gate valve with anti-theft function. Background technique [0002] In the urban water supply and drainage pipe network, water supply and drainage community, landscaping, farmland irrigation, fire protection, petroleum, district heating, power plants, sewage and other industries, gate valves are required to control the flow of media in the pipeline. However, some individuals violated the regulations and opened and closed the gate valve without authorization, causing losses to the heating company and water supply company. Contents of the invention [0003] The invention proposes a double anti-theft gate valve, which solves the problem in the prior art that the gate valve is easy to be opened and closed by non-professionals. [0004] Technical scheme of the present invention is realized like this: [0005] A double anti-theft gate valve includes a valve body, a valve stem and a valve cover, the...
