Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0010] figure 1 As shown, valve disc 2 is installed in valve body 1 to cooperate with the sealing surface of valve body 1, valve body 1 is connected with valve cover 3 by bolts, the middle part of valve cover 3 is equipped with valve stem 4, and the lower part of valve stem 4 is connected with valve disc 2, A valve stem nut is equipped with on the valve stem 4 top, and the periphery of the valve stem nut is equipped with a hand wheel.

[0011] The valve is welded and connected to the pipeline device by socket type. It can be realized that the long-term use of a valve is not easy to produce leakage phenomenon.

Abstract

The invention discloses a socket type carbon steel stop valve which comprises a valve body, a valve flap, a valve rod and a valve cover. The socket type carbon steel stop valve is characterized in that the valve is in socket connection with a pipeline device. By virtue of the socket type carbon steel stop valve, the phenomenon that stop valves designed and produced in the current society are universally connected through flanges and are liable to leak during long-term use can be solved. The socket type stop valve is widely applicable to the field of flow control of pipeline devices of liquid and gas.

Description

technical field [0001] The invention relates to the field of flow control of liquid and gas pipelines, in particular to a control valve for adjusting the flow of liquid and gas in pipeline devices. Widely used in petroleum, chemical, refining, metallurgy and other pipeline control devices. Background technique [0002] At present, the connection form of the stop valve designed and produced in the society is flange connection, which is prone to leakage after long-term use. Contents of the invention [0003] In order to solve the problem that the flange connection type of ordinary valves is prone to leakage after long-term use, the invention invents a socket type stop valve. [0004] The technical solution of the present invention is a carbon steel socket-type globe valve, which is composed of a valve body, a valve disc, a valve cover, a valve stem, etc. The special feature is that the valve connection adopts a socket-type welding connection, which is not easy to use for a...
