Abstract
The utility model discloses a stop valve for a high-pressure slurry pipeline. The stop valve comprises a valve body, a valve rod and a valve core, wherein the valve rod is connected with the valve body through a valve clack arranged in the valve body; the other end of the valve rod is arranged in the valve body and connected with the valve core; the top of the valve rod is connected with a handle; a frustum-shaped hollow bracket is arranged on the handle; an operating rod is arranged on the bracket and is connected with the valve rod through a connection rod in a transmission manner; the valve body comprises an inlet and an outlet; a rubber anti-corrosion layer is lined in the valve body; an included angle between the handle and a horizontal plane of the valve body is 45 degrees; a step is arranged at one end of the handle. The stop valve has the beneficial effects that the valve rod is in angle connection with the valve body, so that resistance produced by fluid to the valve rod can be effectively reduced when the stop valve is closed; the rubber layer is lined in the valve body, so that the stop valve can bear extremely strong impact force and friction force which are produced by the high-pressure fluid; the service life of the stop valve is prolonged.
Description
Technical field
The utility model relates to valve field, and relating to especially a kind ofly stops valve for the high pressure slurry pipeline.
Background technique
Stop valve, be current most popular a kind of valve, and this valve in use has durable, easy to manufacture, easy to use, in not being only applicable to, low pressure, and also operable advantage in high pressure.But the stop valve on the high pressure slurry pipeline in use, still there are some problems, as large as the resistance due to fluid, force rate required during opening and closing is larger, cause its adjusting function poor, the stamping press and the frictional force that due to factors such as overpressure or pressure instabilities, produce again, also can make flap shortening in working life, and have a strong impact on the stability of flow adjusting, thereby make stop valve lose function.
The model utility content
For the deficiencies in the prior art, the purpose of this utility model is, provides a kind of high pressure slurry pipeline can also reduce the stop valve of fluid resistance.
In order to achieve the above object, technical solution adopted in the utility model is:
A kind of for high pressure slurry pipeline stop valve, comprise valve body, valve rod and spool, valve rod is connected with valve body by the flap be arranged in valve body, and the other end of valve rod is arranged in valve body and is connected with spool, the top connection of valve rod arranges handle, on described handle, be provided with the frustoconic shape hollow sting, on described support, be provided with operating handle, described operating handle is connected by link transmission with described valve rod, described valve body includes an inlet and an outlet, in described valve body, be lined with the rubber anti-corrosive layer, between the horizontal plane of described handle and valve body, angle is 45 degree, handle one end is provided with step.
Valve rod is angle with valve body and is connected setting, with the spool corresponding part, is provided with baffle plate in valve body, and handle adopts worm gear pole mechanism to be connected with valve rod, and described worm gear is arranged on the top of valve rod.
The beneficial effects of the utility model; Stop valve of the present utility model, valve rod is angle with valve body and is connected, make stop valve can effectively reduce the resistance that fluid produces valve rod when closing, with the valve inner of spool corresponding part, be provided with the sealing that baffle plate can increase stop valve, increase its working life, handle is in transmission connection by worm-and-wheel gear and valve rod, further reduced the needed power of switch stop valve, in valve body, be lined with rubber layer, can tolerate stamping press and frictional force that high-pressure liquid is huge, extend the working life of stop valve.The resistance that the stop valve of this structure not only can reduce stop valve effectively while closing and simple in structure, easy to operate, be convenient to maintenance more.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, describe implementation process of the present utility model in detail:
A kind of for high pressure slurry pipeline stop valve, comprise valve body 1, valve rod 2 and spool 4, valve rod 2 is connected with valve body 1 by the flap 3 be arranged in valve body 1, and the other end of valve rod 2 is arranged in valve body 1 and is connected with spool 4, the top connection of valve rod 2 arranges handle 5, on described handle 5, be provided with frustoconic shape hollow sting 6, on described support 6, be provided with operating handle 7, described operating handle 7 is connected by link transmission with described valve rod 2, described valve body 1 comprises entrance 10 and outlet 9, in described valve body 1, be lined with the rubber anti-corrosive layer, between the horizontal plane of described handle 5 and valve body 1, angle is 45 degree, handle 5 one ends are provided with step.
Valve rod 2 is angle with valve body 1 and is connected setting, with spool 4 corresponding parts, is provided with baffle plate 8 in valve body 1, and handle 5 adopts worm gear pole mechanism to be connected with valve rod 2, and described worm gear is arranged on the top of valve rod 2.
The beneficial effects of the utility model; Stop valve of the present utility model, valve rod is angle with valve body and is connected, make stop valve can effectively reduce the resistance that fluid produces valve rod when closing, with the valve inner of spool corresponding part, be provided with the sealing that baffle plate can increase stop valve, increase its working life, handle is in transmission connection by worm-and-wheel gear and valve rod, further reduced the switch stop valve needed, in valve body, be lined with rubber layer, can tolerate stamping press and frictional force that high-pressure liquid is huge, extend the working life of stop valve.The resistance that the stop valve of this structure not only can reduce stop valve effectively while closing and simple in structure, easy to operate, be convenient to maintenance more.
