Description

Technical Field

[0001] This utility model relates to the field of valve sealing technology, and more specifically, to a pneumatic valve seal. Background Technology

[0002] Pneumatic valves utilize compressed air to drive multiple sets of combined pneumatic pistons within the actuator. During installation, ensuring a tight seal between the valve and the pipeline is crucial. Typically, a sealing element is installed at the valve-pipe connection. For example, patent CN218913885U discloses a pneumatic valve seal. During the connection process between the sealing ring and the inlet / outlet of the pneumatic valve body, the user moves the sealing ring along the inlet / outlet of the valve body via the outer ring. When the outer ring is close to the inlet / outlet, the support block and anti-slip strip are subjected to pressure from the inlet / outlet. The force causes the support block to move inward toward the inside of the slot, simultaneously driving the output end of the damping rod downward. During the downward movement of the damping rod, under the support of the auxiliary plate, the limit spring is compressed along the inside of the movable groove until multiple sets of support blocks are pressed against the inside of the slot. At this point, the anti-slip strip deforms, causing the outer ring to press against the inner wall of the inlet and outlet, until the sealing ring is fitted against the flange on the outside of the pneumatic valve body's inlet and outlet. Rotating the sealing ring allows the mounting hole to align with the corresponding hole on the flange, thereby improving the stability of the sealing ring and facilitating its sealing performance.

[0003] When the above-mentioned device is in use, the outward squeezing force generated by the limiting spring and support block in the auxiliary structure further increases the upward tension of the seal itself on its circumference. This ensures that when the seal is installed on the pneumatic valve interface, it can be fixed to the interface by the tension generated by itself, eliminating the need to press and fix the seal when docking the interface, thus improving the convenience of operation. The setting of the pressure sensing component ensures that the sealing ring plays a pressure coordination role between the pneumatic valve body and the corresponding pipeline connection, thereby avoiding the phenomenon of stripping and breakage due to excessive rotation force of the nut, improving the practicality of the sealing ring. However, its structure is relatively complex. When inserting the outer ring into the pneumatic valve, multiple support blocks need to be pressed inward, which is inconvenient to operate. At the same time, the damping rod will also apply reverse pressure to the outer ring, affecting the sealing performance of the outer ring and the inner wall of the valve. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pneumatic valve seal. The technical problem to be solved by the present invention is: how to increase the sealing performance and ease of installation of the valve seal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic valve seal, including a sealing gasket body, a sealing ring provided on the outer side of one end of the sealing gasket body, a concave mounting groove provided inside the sealing ring, and a plurality of limiting slots provided on one side of the inner end face of the concave mounting groove.

[0006] The outer end face of the sealing gasket body is provided with a concave adapter groove, the inside of the concave mounting groove is provided with an annular support pad, and one side of the outer end face of the annular support pad is provided with multiple limiting blocks.

[0007] In a preferred embodiment, a strip-shaped limiting groove is formed on the inner end face of the concave adapter groove.

[0008] In a preferred embodiment, a sealing connecting ring is provided inside the concave adapter groove.

[0009] In a preferred embodiment, strip-shaped connecting blocks are provided on both sides of the outer end face of the sealing connecting ring.

[0010] In a preferred embodiment, both the sealing gasket body and the sealing connecting ring have multiple locking connection holes on their end faces.

[0011] In a preferred embodiment, both the sealing gasket body and the sealing ring are made of rubber, and the inner end face of the concave mounting groove is adapted to the outer end face of the annular support pad.

[0012] In a preferred embodiment, the inner end face of the limiting slot is adapted to the outer end face of the limiting block, and the inner end face of the concave adapter groove is adapted to the outer end face of the sealing connecting ring.

[0013] In a preferred embodiment, both the annular support pad and the sealing connecting ring are metal components. The inner end face of the strip-shaped limiting groove is adapted to the outer end face of the strip-shaped connecting block. The sealing pad body and the sealing connecting ring end faces are provided with locking connection holes, and their inner end faces in the main viewing direction are coplanar.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In practical use, this invention effectively increases the stability of the annular support pad installation by correspondingly setting the annular support pad, concave mounting groove, limiting slot, and limiting plug, preventing deformation and slippage of the annular support pad after the sealing plug is installed. At the same time, when the sealing plug is inserted into the pneumatic valve, the annular support pad supports the sealing plug, thereby ensuring that the sealing plug fits tightly into the inside of the pneumatic valve, effectively increasing the sealing performance of the pneumatic valve installation. In addition, its simple structure can effectively increase the service life of the sealing components, and the installation is also relatively convenient. Attached Figure Description
