Embodiment Construction

[0011] Depend on figure 1 Shown, the present invention is an integral design.

[0012] figure 2 , the gas enters the valve body from the ball end of the valve.

[0013] In the left part of the valve body, the valve ball (1) is sealed in the lower valve body (10) by the valve seat (2). Under normal use conditions, the air channel of the valve ball (1) is connected to the gas channel, and the gas passes through the air channel of the valve ball. When closing the ball, turn clockwise figure 1 The handle in the handle drives the valve ball (1) to rotate, unscrews the air passage of the valve ball, blocks the gas passage with the body of the valve ball, and realizes the shut-off of the gas passage. Such as image 3 shown.

[0014] On the right side of the valve body, the gasket (7) separates the valve body into upper and lower parts. The upper valve body (6) is the control part, and the lower valve body (10) is the operating part. The gasket (7) will Gas is sealed in the lo...

Abstract

The invention discloses a mechanical and electrical integrated emergency shut-off valve, which is used in a civil gas pipeline and is used for solving the problem of increase of the number of pipeline installation junctions in intelligent control of the gas pipeline. A manual valve ball and an electromagnetic stopper are arranged inside a valve body; the manual valve ball and the electromagnetic stopper are arranged sequentially; the valve can be manually shut off during normal use, the valve can be automatically shut off under the control of external monitoring equipment in emergency, such as gas leakage; and the number of the pipeline junctions is not increased.

Description

technical field [0001] The invention is a civil gas pipeline cut-off valve which integrates manual control and electric control. In addition to normal daily use, in case of emergency (such as: leakage) in the pipeline, it can be automatically shut down by external monitoring equipment. Background technique [0002] At present, civil gas pipelines are shut off by manual ball valves. The manual ball valve uses the rotation of the valve ball in the valve body to achieve the purpose of blocking the pipeline, and has good reliability. However, the manual ball valve is not intelligent, and cannot be automatically closed in case of gas leakage during gas use. Although an electromagnetic shut-off valve can be added behind the manual ball valve to increase the intelligent control of shutting off the gas pipeline, the addition of an electromagnetic shut-off valve also increases the number of joints on the pipeline and increases the number of gas leakage points. Contents of the inv...
