Description

Technical Field

[0001] This utility model belongs to the technical field of novel rubber sealing valve seats for valves, and more specifically, it relates to a novel rubber sealing valve seat for valves. Background Technology

[0002] The detachable surface component inside the valve is used to support the valve core in the fully closed position and form a sealing pair. Generally, the valve seat diameter is the maximum flow diameter of the valve. For example, the valve seat material of butterfly valves is very extensive. Various rubber, plastic and metal materials can be used as valve seat materials.

[0003] Currently, valve seats are mainly used to support valve cores. With long-term use of valves, due to the pressure inside the pipeline, valve seats are prone to cold deformation under load, causing deformation and reducing the sealing performance of the valve, thus affecting its normal use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a new type of rubber sealing valve seat for valves, in order to achieve a more practical value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a novel rubber sealing valve seat for valves, which is achieved by the following specific technical means:

[0006] A novel rubber-sealed valve seat for valves includes a first sealing ring, a bellows fixedly connected to one side of the first sealing ring, and a second sealing ring fixedly connected to the other side of the bellows. The first sealing ring has a plurality of first connecting blocks on the side adjacent to the second sealing ring, and the second sealing ring has a plurality of second connecting blocks on the side adjacent to the first sealing ring. A compression spring is provided between each of the plurality of first connecting blocks and the plurality of second connecting blocks.

[0007] Furthermore, the corrugated pipe is made of polyethylene.

[0008] Furthermore, a first through groove is provided at the top end of the corrugated pipe, and the first through groove extends through the bottom end of the corrugated pipe.

[0009] Furthermore, a second through groove is provided at the bottom end of the corrugated pipe, the second through groove passing through the bottom end of the corrugated pipe and corresponding to the position of the first through groove.

[0010] Furthermore, both the first and second sealing rings are made of rubber.

[0011] Furthermore, the compression spring is made of stainless steel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the combined use of the first connecting block, the second connecting block, and the compression spring enables the valve seat to automatically and conveniently adapt to the pressure of the pipeline and deform accordingly, maintaining good sealing performance at all times. The bellows allows the compression spring to easily adjust its shape. Attached Figure Description

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] This utility model provides a novel rubber sealing valve seat for valves, including a first sealing ring 1, a bellows 2 fixedly connected to one side of the first sealing ring 1, a second sealing ring 3 fixedly connected to the other side of the bellows 2, a plurality of first connecting blocks 4 provided on the side of the first sealing ring 1 adjacent to the second sealing ring 3, a plurality of second connecting blocks 5 provided on the side of the second sealing ring 3 adjacent to the first sealing ring 1, and a compression spring 6 provided between each of the plurality of first connecting blocks 4 and the plurality of second connecting blocks 5.

[0025] Among them, the corrugated pipe 2 is made of polyethylene, which has good chemical corrosion resistance.

[0026] The corrugated pipe 2 has a first through groove 7 at its top end, which extends through the bottom end of the corrugated pipe 2.

[0027] The corrugated pipe 2 has a second through groove 8 at its bottom end. The second through groove 8 passes through the bottom end of the corrugated pipe 2 and corresponds to the position of the first through groove 7. The arrangement of the first through groove 7 and the second through groove 8 facilitates its installation.

[0028] The first sealing ring 1 and the second sealing ring 3 are both made of rubber, which has excellent elasticity and wear resistance.

[0029] Among them, the compression spring 6 is made of stainless steel, which has good corrosion resistance and a long service life.

[0030] The working principle of this embodiment: This utility model is installed on a valve and used. The first sealing ring 1, the bellows 2, and the second sealing ring 3 are sequentially fitted onto the valve. When the valve is in use, the high pressure inside the pipeline will affect the valve seat, causing it to deform. At this time, the compression spring 6 at the first connecting block 4 and the second connecting block 5 will deform along with the deformation of the entire valve seat. Then, the bellows 2 will return to its original position through its own elasticity, ensuring that the valve seat always has good sealing performance.

[0031] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
