Embodiment Construction

[0033] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0034] like figure 1 , figure 2 and image 3As shown, the gas magnetic locking ball valve includes a valve body 1 and a valve stem 2 and a ball core 3 which are both arranged in the valve body 1. The lower end of the valve stem 2 is connected to the ball core 3. The hole 3a, the upper end of the valve stem 2 extends out of the upper end of the valve body 1 and is connected with a handle 4 . Wherein, the upper end of the valve stem 2 has a coupling portion 2a, the handle 4 has a coupling hole 4a matching the shape of the coupling portion 2a, and the coupling portion 2a is inserted into the coupling hole 4a so that the two are fixed along the circumferential direction. Specifically, the top surface of the handle 4 is pro...

Abstract

The invention provides a fuel gas magnetic locking ball valve, and belongs to the technical field of valves. The problem that the limiting precision is low is solved. The fuel gas magnetic locking ball valve comprises a valve body, a valve rod and a handle connected to the upper end of the valve rod, a connecting part is arranged at the upper end of the valve rod, the handle is provided with a connecting hole matched with the connecting part, the two ends of the connecting hole are through, the top of the connecting part is in threaded connection with a limiting screw preventing the handle from being separated from the connecting part, and the upper end of the valve body is detachably connected with an annular metal limiting piece at the extending position of the valve rod. The metal limiting piece and the valve body are fixed in the circumferential direction, two protruding pieces are arranged on the inner edge of the metal limiting piece, limiting notches are formed between the two adjacent side walls of the two protruding pieces in the circumferential direction respectively, the connecting part penetrates through the metal limiting pieces, and when the valve rod rotates, the connecting part can move along the two limiting notches to abut against the two protruding pieces at the same time, and gaskets are arranged on the metal limiting pieces. The gaskets are elastic and abuts against the lower side of the handle and the metal limiting pieces. The fuel gas magnetic locking ball valve has the advantages of high limiting precision, wide applicability and the like.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a gas magnetic locking ball valve. Background technique [0002] Ball valves are mainly used for cutting, distributing and changing the flow direction of media. They are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries. The traditional ball valve only has the function of controlling the opening and closing of the pipeline, and anyone can operate it at will. For this reason, various ball valves with locking functions have appeared on the market, among which magnetic locking ball valves are the most popular. At present, the structure of most magnetic locking ball valves is roughly the same. A handle is connected to the upper end of the valve stem, and a magnetic locking mechanism is provided between the handle and the valve body. The magnetic locking mec...
