进口蝶阀Product Description:

The double eccentric butterfly valve with high sealing performance and convenient opening and closing can automatically clean impurities and have strong sealing effect. The utility model relates to a double eccentric butterfly valve with high sealing and convenient opening and closing, which comprises a main frame, and a water inlet is arranged on the main frame; A water outlet is arranged on the main frame; The upper side of the main frame is rotationally provided with a rotary sealing plate; A rotating mechanism is arranged on the main frame; A connecting mechanism is arranged between the water inlet and the water outlet. The clean water flows into the water outlet through the water inlet, and the clean water flows into another water pipe through the water outlet. The user can control the flow rate of the clean water according to the actual situation and referring to the value on the indicator plate, so as to realize the effect of rotating the sealing plate to control the flow of the clean water.

The double eccentric butterfly valve with high sealing and convenient opening and closing is characterized in that it also includes a pushing mechanism, which includes: an upper connecting frame, and the four positioning half frames are provided with an upper connecting frame); The four upper connecting frames are rotatably provided with narrow connecting plates; The four narrow connecting plates are slidably provided with hollow connecting frames; The upper and lower sides of the two connecting rings are provided with lower connecting frames, which are connected with the hollow connecting frame; The third return spring is connected between the narrow connecting plate and the hollow connecting frame, and the number of the third return spring is eight.

进口蝶阀Principle:

The opening and closing part of the butterfly valve is a disc-shaped butterfly plate disc, which rotates around the axis of the valve stem in the valve body, so as to achieve the purpose of opening, closing or adjustment. The closed butterfly valve seals and blocks the liquid flow through the close fitting of the sealing surface between the valve disc and the valve seat. The close fitting of the sealing surface between the valve disc and the valve seat needs to rely on a large driving force to produce a certain amount of elastic deformation. The tighter the sealing surface is squeezed, the better the sealing effect, Therefore, in order to achieve the ideal sealing effect, its opening and closing resistance is also relatively large, which brings constant to the operation, and there will be large friction in the process of valve opening and closing, so the sealing surface is easy to be damaged and there is no elastic compensation, resulting in sealing failure.
