Abstract
The utility model relates to a threaded check valve, composed of a valve body, a valve clack, a valve cap and a valve rod. The utility model is characterized in that a valve is connected with a pipeline device by a screw thread. The utility model solves the problems that connecting mode of the existing check valve adopts welding connection and leakage is easy to happen when in long term use. The threaded check valve of the utility model is widely applied to the field of flow control of liquid and gas pipeline devices.
Description
Technical field
The utility model relates to the flow control field of the pipeline of liquid, gas, the control valve of specifically a kind of adjutage duct device liquid, gas flow.Be widely used in pipeline control gear such as oil, chemical industry, oil refining, metallurgy.
Background technique
Social at present its Connecting format weld seam of stop valve of going up design production connects, and uses easily generation leakage phenomenon for a long time.
Summary of the invention
The utility model connects for solving the common valve weld seam, and the long-term problem of leaking that easily produces of using is invented a kind of thread type stop valve.
The technical solution of the utility model is that a kind of thread type stop valve is made of valve body, flap, valve gap, valve rod, Stem Mut, handwheel.Its special way is that valve connects the employing screw type and connects, and during maintenance, by screw thread rotation, valve is taken out.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, can realize that a kind of valve is threaded with tube equipment, and long-term the use is convenient to dismounting and maintenance and replacing phenomenon.
