Sealing valve for pipeline valve

Abstract

The invention discloses a sealing valve for a pipeline valve. The sealing valve comprises a valve body, a valve rod and a pressing plate, wherein the valve rod is arranged at the middle of the valve body; the pressing plate is arranged at the lower end of the valve rod; a disc-shaped sealing gasket is arranged on one side of the pressing plate; a gate plate is connected between the disc-shaped sealing gasket and the pressing plate; a valve rod sealing layer is arranged at the upper part of the valve rod; a middle cover is arranged below the valve rod sealing layer; a middle cover sealing layer is arranged at both ends of the middle cover; a pin is arranged at the upper end of the valve rod sealing layer; a plurality of springs are symmetrically arranged at two ends of the pin; movable clamps are arranged on the springs; a magnetic material is arranged on the movable clamps; a valve cover is arranged at the upper end of the magnetic material; and rivets are symmetrically mounted at tow ends of the lower part of the valve cover. The structure of the sealing valve has the advantages that through the arranged valve body, all parts of the sealing valve can be positioned in a steady environment and are not easy to damage, the service life of the sealing valve is prolonged, and then the production cost is reduced; and through the arranged valve cover, impurities can be prevented from entering the sealing valve, the working efficiency is improved, and the sealing performance is good.

Description

technical field [0001] The invention relates to a pipeline valve, in particular to a sealing valve for a pipeline valve. Background technique [0002] In China, most of the pipeline valve structures currently used in pipelines realize the opening of the valve through the valve stem connected to the valve seat control part in the valve seat. The tool on the rod rotates the valve rod to realize the opening of the valve, so that the pipeline valves cannot be managed uniformly, and the pipeline valves are often damaged, and pipeline resources such as water, steam, and oil are lost. In the existing magnetic locking valves, usually in order to meet the needs of mass production, the magnetic locking mechanism and the unlocking mechanism of the magnetic key are generally designed as a common structure, that is, they are all located on the 90-degree end wall between the upper bonnet and the bonnet. There are upper and lower lock holes corresponding to each other on the body, and a l...

[0002] In China, most of the pipeline valve structures currently used in pipelines realize the opening of the valve through the valve stem connected to the valve seat control part in the valve seat. The tool on the rod rotates the valve rod to open the valve, so that the pipeline valves cannot be managed uniformly, and the pipeline valves are often damaged, and pipeline resources such as water, steam, and oil are lost.

In the existing magnetic locking valves, usually in order to meet the needs of mass production, the magnetic locking mechanism and the unlocking mechanism of the magnetic key are generally designed as a common structure, that is, they are all located on the 90-degree end wall between the upper bonnet and the bonnet. There are upper and lower lock holes corresponding to each other on the body, and a lower magnetic steel is installed between the lower lock hole and the upper lock hole, and then there is an unlocking lock at the position corresponding to the magnetic key and the upper lock hole on the upper valve cover. The upper magnetic steel, this kind of magnetic lock valve magnetic key has strong versatility, and the opening and closing protection performance is weak. During use, people can open and close it as long as they have any magnetic key, so as to realize illegal opening. The purpose of anti-theft protection is not in place
