Description

Self-adjusting the NewTorq elastic seat with pressure changes

This creation is about a valve seat, especially a self-adjusting NewTorq elastic valve seat that can be adjusted with pressure.

Conventional applications of valves below the rated pressure, although able to meet the needs of the work. However, with the increase of the use time and the random change of the pressure, the conventional valve is prone to poor sealing effect, which leads to fluid leakage and the like.

The valve seat of the conventional butterfly valve has a sealing capacity with the seat plate, and the smaller the pressure, the better the sealing effect. Since the sealing force of the conventional butterfly valve cannot be adjusted independently with the pressure change, when the pressure is increased, a gap is easily generated between the valve seat plate and the valve seat, thereby causing fluid leakage.

In view of the above problems and shortcomings of the prior art, the main purpose of the present invention is to provide a self-adjusting NewTorq elastic valve seat with pressure changes, thereby solving the valve seat of the conventional butterfly valve, which cannot be changed with pressure. The lack of self-regulation. Furthermore, the valve of the butterfly valve can be adjusted according to the fluid pressure, and the purpose of adjusting the sealing degree is adjusted independently.

According to the above object of the present invention, a NewTorq elastic valve seat is self-adjusted with pressure change, wherein the valve seat is a hollow structure, and a first bearing surface and a second bearing surface are disposed on both sides of the valve seat; The first bearing surface and the second bearing surface are gradually gathered outwardly, intersecting at a predetermined intersection, and extending along the junction to provide a first sealing plate and a second sealing plate; the first bearing surface and the first The inside of the two pressure-bearing faces is provided with a rectangular plate sealing surface.

The elastic member is made of an elastic material and is made of one of rubber, silicone or fluorine rubber, such as an O-ring. Or made of a metal elastomer, such as a metal spring.

The rectangular plate sealing surface has a circular arc shape at both ends.

The NewTorq elastic valve seat self-adjusting with pressure change described in the present invention can achieve at least the following progressive benefits: when implemented in a butterfly valve, the pressure plate of the butterfly valve is connected to the valve body of the butterfly valve at the junction, when the first After the pressure receiving surface or the second bearing surface is subjected to the pressure of the fluid medium, the first bearing surface or the second bearing surface is deformed by the pressure of the fluid, so that the first bearing surface or the second bearing surface automatically bypasses the meeting point. Offset, the rectangular plate sealing surface is subjected to the pressure transmitted by the first bearing surface or the second bearing surface to the disc valve plate, which makes a more tight sealing contact with the butterfly valve disc plate.

As the fluid pressure increases, the first or second bearing surface deforms more and the displacement is larger, thereby pushing the rectangular plate sealing surface to rotate around the junction, resulting in It has a larger sealing effect with the disc valve plate, so that it can achieve self-adjustment and adjustment of the seal with pressure changes.

The self-adjusting elastic valve seat with pressure change described in this creation is also called a NewTorq valve seat. A butterfly valve using this inventive solution is called a NewTorq butterfly valve.

The first picture is a schematic diagram of the self-adjusting elastic valve seat with the pressure change.

Fig. 2 is a schematic cross-sectional view showing the embodiment of the butterfly valve according to the self-adjusting elastic valve seat of the present invention.

Hereinafter, please refer to the related drawings to further explain the self-adjusting NewTorq elastic valve seat embodiment of the present invention. In order to facilitate the understanding of the present embodiment, the same components are denoted by the same symbols.

Please refer to Figures 1 and 2. In the figure, the NewTorq elastic valve seat is self-adjusted with the pressure change, wherein the valve seat body is a hollow structure, and the first bearing surface 1 and the second bearing surface 2 are provided on both sides of the valve seat; The pressure bearing surface 1 and the second pressure bearing surface 2 are gradually gathered outwardly, intersect at a predetermined intersection point 7, and extend outward along the junction point 7, and are provided with a first sealing pressure plate 5 and a second sealing pressure plate. 6. An elastic member 3 is disposed between the first pressure receiving surface 1 and the second pressure receiving surface 2.

The elastic member 3 is an elastic material. The elasticity and rigidity of the elastic member 3 assembled or added according to the use environment, medium and pressure of the butterfly valve can be changed according to the requirements of the implementation, so as to have corresponding elasticity and Necessary rigidity. Therefore, the elastic member 3 can be selectively made of rubber, silicone or fluoro rubber, such as an O-ring, or a metal elastomer, such as a metal spring, but the elastic member 3 is a closed structure. The overall is good, but not limited to this.

A rectangular disc sealing surface 4 is disposed on the inner side of the first pressure receiving surface 1 and the second pressure receiving surface 2, and the rectangular disc sealing surface 4 is in contact with the butterfly valve disc 12, and the end angles thereof may be circular arc shapes. structure.

By the composition of the above components, it is implemented in the butterfly valve. The valve seat body first sealing platen 5 and the second sealing platen 6 are mounted on the butterfly valve body 13 in cooperation with the butterfly valve pressing plate 11, and the butterfly valve pressing plate 11 is sealed by the first sealing platen 5 and the second sealing platen 6 and the butterfly valve body 13 connection. The butterfly valve disc 12 is sealingly connected to the disc sealing surface 4 by operating the butterfly valve stem 8.

At the junction 7 facing the butterfly valve platen 11, a platen gap 9 is provided between the second pressure receiving surface 2 and the pressure plate 11. The junction point 7 faces the side of the butterfly valve body 13, and a valve body gap 10 is also provided between the first pressure receiving surface 1 and the butterfly valve body 13.

When the fluid enters the platen gap 9, the pressure of the fluid acts on the second pressure receiving surface 2, or when the fluid enters the valve body gap 10, and the pressure of the fluid acts on the first pressure receiving surface 1, the valve seat occurs in the direction of fluid movement. Deformation and automatic bypass The sinker 7 rotates and is displaced, and the rectangular disc seal surface 4 in sealing contact with the butterfly disc plate 12 is subjected to pressure from the first pressure receiving surface 1 or the second pressure receiving surface 2 to act on the butterfly disc plate 12, so that The disc seal face 4 and the butterfly disc plate 12 form a more tight seal strength. In turn, the purpose of self-adjusting and adjusting the seal with pressure changes is achieved.
