Description

TECHNICAL FIELD

[0001] The utility model belongs to valve technical field, concretely is plug-in sleeve type cone valve structure. BACKGROUND

[0002] The fixed cone valve is a commonly used energy dissipation and flow regulating device in water conservancy projects, and is commonly used for water head reduction and water discharge regulation at the outlet end of a discharge pipeline to reduce the impact of high-speed water flow at the pipeline outlet on downstream river channels, canals and tunnels.

[0003] In a conventional cone valve, the water flow enters the flow guide cover in a ring-shaped jet after passing through the cone valve, while the plug-in sleeve type energy dissipation cone valve divides the original cone valve body into two parts, and the water flow forms two ring-shaped jets that are not parallel to each other after passing through the plug-in sleeve type cone valve. The jets collide with each other at the valve port, thereby consuming part of the energy and then entering the flow guide cover, thereby improving the energy dissipation efficiency. Therefore, we propose a plug-in sleeve type cone valve structure. SUMMARY

[0004] To solve the above problems, the utility model provides the following technical scheme: a plug-in sleeve type cone valve structure, comprising a valve body, which is internally provided with a channel for guiding fluid flow;

[0005] A flow guide cone cylinder is arranged in the valve body and connected with the flow passage of the valve body for guiding the flow of fluid and ensuring the flow direction and flow rate of the fluid in the valve body;

[0006] A sleeve gate can slide in the flow guide cone cylinder to control the on-off of the fluid, and the sleeve gate and the flow guide cone cylinder are tightly matched through a sealing structure to prevent leakage;

[0007] A flow guide cover is arranged outside the valve body and surrounds the flow guide cone cylinder, and is fixedly connected with the valve body, the flow guide cover is used for guiding and uniformly distributing the fluid, and optimizing the flow state of the fluid;

[0008] A flow dividing cone is arranged in the flow guide cone cylinder, and the flow dividing cone divides the flow passage in the flow guide cone cylinder into two branches, thereby further guiding the fluid and distributing the flow.

[0009] Further, a plurality of flow guide fins are arranged in the flow guide cone cylinder, and the flow dividing cone is welded to the tail end of the flow guide fins.

[0010] Compared with the prior art, the utility model has the advantages of:

[0011] When the inlet end has the same water inflow and water head:

[0012] 1. The plug-in sleeve type cone valve can reduce the flow rate and pressure of the water flow entering the flow guide cover from the valve port;

[0013] 2. The plug-in sleeve type cone valve can reduce the average flow velocity of the real flow area of the water flow in the downstream pipeline, and is beneficial to the cooperation with the downstream flow guide cover. BRIEF DESCRIPTION OF DRAWINGS

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application; based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] By Figure 1 It is given that the present application comprises a valve body 1, which is internally provided with a channel for guiding fluid flow;

[0019] The flow guide cone cylinder 2 is arranged in the valve body 1 and connected with the flow passage of the valve body 1, for guiding the flow of fluid and ensuring the flow direction and flow rate of the fluid in the valve body 1;

[0020] The sleeve gate 3 can slide in the flow guide cone cylinder 2 and control the on-off of the fluid, and the sleeve gate 3 and the flow guide cone cylinder 2 are tightly matched through a sealing structure to prevent leakage;

[0021] The flow guide cover 4 is arranged outside the valve body 1 and surrounds the flow guide cone cylinder 2, and is fixedly connected with the valve body 1, and the flow guide cover 4 is used for guiding and uniformly distributing the fluid and optimizing the flow state of the fluid;

[0022] The flow distribution cone 5 is arranged in the flow guide cone cylinder 2, and the flow distribution cone 5 divides the flow passage in the flow guide cone cylinder 2 into two branches, and plays a role of further guiding the fluid and distributing the flow.

[0023] A plurality of flow guide fins are arranged in the flow guide cone cylinder 2, and the flow distribution cone 5 is welded to the tail end of the flow guide fins.

[0024] When the plug-in energy dissipation cone valve is used, the high flow velocity area in the fairing 4 is changed, and the water flow velocity at the outlet end of the cone valve is smaller than that when the conventional energy dissipation cone valve is used because the water flow velocity has been collided and dissipated once.
