Problems solved by technology

[0002] With the development of society, the application of valves is very wide, and the medium to be transported is becoming more and more complex. While we require to reduce wear, we also have higher requirements for the sealing performance of the valve. If the sealing performance is not good, it will produce medium The problem of leakage will cause a lot of economic losses, and the volatile toxic substances may endanger people's lives, so sealing technology has become a top priority

Embodiment 1

[0039] Such as figure 1 and figure 2 As shown, the valve structure of Embodiment 1 includes a flow regulating member 20 , an elastic sealing member 30 and a sealing cover 40 . The flow regulating member 20 is used to be movably arranged on the connecting pipe 10 , the flow regulating member 20 passes through the installation hole 13 of the connecting pipe 10 and is partly located in the connecting pipe 10 . The elastic sealing member 30 is used to be disposed between the connecting pipe 10 and the flow adjustment member 20 and to seal the gap between the flow adjustment member 20 and the installation hole 13 . The sealing cover 40 is used for being arranged on the connecting pipe 10 and covering the outside of the flow regulating part 20 .

[0040] Applying the technical solution of this embodiment, an elastic seal 30 is provided between the connecting pipe 10 and the flow regulating member 20 , so as to prevent the medium in the connecting pipe 10 from leaking from the gap...

Embodiment 2

[0050] From image 3 It can be seen that in the second embodiment, the plunger 211 is a hollow structure, and the lower end of the lead screw 221 extends downward into the plunger 211 . And the plunger 211 is provided with embedded parts, and the lower end of the lead screw 221 is welded on the embedded parts. The top of the plunger 211 is provided with a cover plate, and the middle part of the lead screw 221 is welded on the cover plate.

[0051] Such as image 3 As shown, in the technical solution of the second embodiment, the cross-sectional shape of the lower end of the plunger 211 is arc. Preferably, the outer surface of the lower end of the plunger 211 is a spherical surface.

[0052] Such as image 3 As shown, in the technical solution of the second embodiment, the elastic sealing member 30 cooperates with the plunger 211 . Specifically, the upper end of the elastic sealing member 30 is connected to the upper end of the plunger 211 .

[0053] Such as image 3 As ...

Embodiment 3

[0062] Such as Figure 4 and Figure 5 As shown, in this embodiment, the above-mentioned first elastic sealing member 31 is connected to the transmission connection portion 22 . That is, the upper end of the first elastic sealing member 31 cooperates with the lead screw 221 . Meanwhile, the lower end of the sealing cover 40 is directly connected to the outer pipe wall of the connecting pipe 10 . The positioning flange 60 is not connected with the sealing cover 40 and is located inside the sealing cover 40 . In this embodiment, the elastic seal 30 may only include the first elastic seal 31 .

Abstract

The invention provides a valve structure with the better sealing performance. The valve structure comprises a flow adjusting piece, an elastic sealing piece and a sealing cover, wherein the flow adjusting piece is used for movably arranged on a connection pipe, passes through an installation hole of the connection pipe and is partially located in the connection pipe; the elastic sealing piece is used for being arranged between the connection pipe and the flow adjusting piece and sealing the gap between the flow adjusting piece and the installation hole; and the sealing cover is used for beingarranged on the connection pipe and covering the flow adjusting piece.

Description

technical field [0001] The invention relates to the technical field of pipeline equipment, in particular to a valve structure. Background technique [0002] With the development of society, the application of valves is very wide, and the medium to be transported is becoming more and more complex. While we require to reduce wear, we also have higher requirements for the sealing performance of the valve. If the sealing performance is not good, it will produce medium The problem of leakage will cause a lot of economic losses, and the volatile toxic substances may endanger people's lives, so sealing technology has become a top priority. Contents of the invention [0003] The main purpose of the present invention is to provide a valve structure with better sealing performance. [0004] In order to achieve the above object, the present invention provides a valve structure, including: a flow regulating member, which is used to be movably arranged on the connecting pipe, the flow...
