Abstract
The utility model discloses a valve cover with an internal thread lifting hole. Bosses which are integrally connected with the valve cover are arranged on two outer shoulders of the valve cover, a screw hole which penetrates through each boss is formed in each boss, and the two bosses are symmetrically arranged. By adoption of the valve cover with the internal thread lifting hole, the problems of difficulty in installation of the valve cover and difficulty in installation and transportation of a valve are solved.
Description
Technical field
The utility model relates to the valve valve gap, particularly a kind of valve gap with the internal thread erection opening.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for flowing of all kinds fluids such as control air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Valve gap is one of vitals of valve.The predominant use of valve gap has two: the one, to the valve rod location, guarantee the normal transmission switch of valve rod.The 2nd, seal action has certain intensity, prevents that inner fluid from flowing out.Large bore valves is because weight issue exists valve gap to be difficult for assembling aborning, and valve inconvenience is installed and transportation problem.
Summary of the invention
The purpose of the utility model is exactly to solve the difficult installation of valve gap, valve inconvenience installation and the problem of transporting.
The technological scheme that the utility model adopts is: a kind of valve gap with the internal thread erection opening, and it is that shoulder is provided with the boss that is connected as a single entity with valve gap in two outsides of valve gap, boss is provided with the screw that gos deep into boss.
Wherein, described two boss are symmetric arrangement.
The beneficial effect that the utility model is obtained is that the valve assembling is convenient in the convenient lifting of described valve gap, has improved manufacturing efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
