Abstract
The invention discloses a carbon steel threaded stop valve which comprises a valve body, a valve flap, a valve cover and a valve rod. The carbon steel threaded stop valve is characterized in that the valve is in threaded connection with a pipeline device. By virtue of the carbon steel threaded stop valve, the phenomenon that stop valves designed and produced in the current society are universally connected through welding lines and are liable to leak during long-term use can be solved. The carbon steel threaded stop valve is widely applicable to the field of flow control of pipeline devices of liquid and gas.
Description
Technical field
The present invention relates to the flow control field of pipeline of liquid, gas, the specifically control valve of a kind of adjutage duct device liquid, gas flow.Be widely used in the pipeline control devices such as oil, chemical industry, oil refining, metallurgy.
Background technique
Present society designs its Connecting format solder design of stop valve of production, Long-Time Service easily produces leakage phenomenon.
Summary of the invention
The present invention is for solving common valve solder design, and Long-Time Service easily produces the problem of leakage, invents a kind of threaded check valve.
Technological scheme of the present invention is, a kind of carbon steel threaded stop valve, is made up of valve body, flap, valve gap, valve rod, Stem Mut, handwheel.That valve connects employing screw type and connects, and during maintenance, by screw thread rotation, is taken out by valve outside it is special.
Technique effect of the present invention is, adopts above-mentioned technological scheme, can realize a kind of valve and be threaded with tube equipment, and Long-Time Service is convenient to dismounting and maintenance and is changed phenomenon.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention, and the accompanying drawing that makes an abstract.
In the drawings, 1 valve body, 2 flaps, 3 valve gaps, 4 valve rods.
Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is further described.
To that indicated in the drawings, coordinate with flap 2 sealing surface at valve body 1, valve body 1 is connected with valve gap 3 bolt, and valve rod 4 is housed in the middle part of valve gap 3, and valve rod 4 bottom is connected with flap 2, and Stem Mut is equipped with on valve rod 4 top, Stem Mut be peripherally equipped with handwheel.
Can realize a kind of valve adopts thread type to connect, and Long-Time Service is convenient to dismounting and maintenance and is changed phenomenon.
