Example Embodiment

[0042] Example:

[0043] see Figure 1-3 , a butterfly valve with an anti-sand particle mechanism, comprising a valve seat 100, a valve plate 200 is rotatably connected in the valve seat 100, a valve stem 300 is rotatably connected to the upper end of the valve seat 100, the valve stem 300 is connected with the valve plate 200, and the valve The seat 100 is provided with an anti-clogging mechanism 400, the lower end of the valve seat 100 is drilled with a conducting port, and the conducting port is provided with a multi-functional blocking mechanism 500. In this solution, when the valve plate 200 is opened to allow water flow in the valve seat 100, the water flow Entering from the left side of the anti-clogging mechanism 400, when passing through the sediment interception net 700, the sediment particles in the water flow will be intercepted by the sediment interception net 700, and the water flow will directly pass through the sediment interception net 700, and be intercepted ...

Abstract

The invention discloses a butterfly valve with a silt particle prevention mechanism, and belongs to the field of butterfly valves. According to the scheme, when a valve plate is opened to enable water flow to circulate in a valve seat, silt particles in the water flow can be intercepted by a silt intercepting net, the water flow directly penetrates through the anti-blocking mechanism, and the silt particles enter the anti-blocking mechanism to be detained; the multifunctional blocking mechanism is taken out to enable the water flow to flow out through the communicating opening, on one hand, the sediment blocking net can block sediment particles in the water flow to the maximum extent, and the sediment particles are retained in the anti-blocking mechanism, so that the sediment particles are not prone to blocking opening and closing of the valve plate; on the other hand, when the anti-blocking mechanism retains the sediment particles, part of water flow enters the anti-blocking mechanism, and the multifunctional blocking mechanism releases heat after making contact with the water flow so as to evaporate the entered water flow and dry the retained sediment particles; therefore, when the multifunctional blocking mechanism is taken out, silt particles can flow out to the maximum extent.

Description

technical field [0001] The invention relates to the field of butterfly valves, and more particularly, to a butterfly valve with a mechanism for preventing sediment particles. Background technique [0002] The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. A disc-shaped butterfly plate rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. A kind of valve, butterfly valve not only has simple structure, small size, light weight, low material consumption, small installation size, small driving torque, simple and rapid operation, but also has good flow regulation function and closing sealing characteristics at the same time, and can also be used for High temperature, high pressure, large diameter, high sealing, long life, excellent adjustment cha...
