Abstract
The present utility model discloses a stop valve. The stop valve is mainly composed of a valve body, a valve rod and a valve core, a valve rod sleeve is arranged outside the valve rod through screw threads, the top end of the valve rod is connected with a handle, the other end of the valve rod is arranged inside the valve body and connected with the valve core, and the valve rod is connected with the valve body in an angle way. In the stop valve with the above structure, the valve rod is connected with the valve body in an angle way, resistance of fluid generated on the valve rod can be effectively reduced when the stop valve is closed.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of stop valve.
Background technique
Stop valve is current most popular a kind of valve, and this valve in use has durable, and is easy to manufacture, repair also more convenient, in not being only applicable to, low pressure, also operable advantage in high pressure.But in use because the resistance of fluid is large, force rate required during opening and closing is larger, causes the relatively poor shortcoming of its adjusting function.
The model utility content
The purpose of this utility model is to provide a kind of stop valve that reduces fluid resistance for the deficiency that solves above-mentioned technology.
In order to achieve the above object, a kind of stop valve that the utility model is designed, it mainly comprises valve body, valve rod and spool, the valve rod outside arranges valve stem casing by screw thread, the top connection of valve rod arranges handle, the other end of valve rod is arranged in the valve body and links to each other with spool, and valve rod is angle with valve body and is connected setting.The stop valve of this structure, valve rod and valve body are the angle setting, so that can effectively reduce the resistance that fluid produces valve rod when stop valve is closed.
In order to increase its sealing, described stop valve is provided with the valve peak with the spool corresponding part in valve body.
More laborsaving for handle is used, described handle adopts worm-and-wheel gear to be connected with valve rod, and described worm gear is arranged on the top of valve rod.
The resulting stop valve of the utility model, valve rod is angle with valve body and is connected setting, so that stop valve can effectively reduce the resistance that fluid produces valve rod when closing, be provided with the valve peak with the valve inner of spool corresponding part, can increase the sealing of stop valve, increase its working life, handle is in transmission connection by worm-and-wheel gear and valve rod, has further reduced the needed power of switch stop valve.The resistance that the stop valve of this structure not only can effectively reduce stop valve when closing, and simple in structure, easy to operate, more be convenient to maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
