Description

Technical Field

[0001] The invention relates to the field of pan plug seals, in particular to a double-sided double-spring pan plug seal. Background Art

[0002] The pan-seal is a high-performance seal with a special spring inside a U-shaped Teflon. The appropriate spring force plus the system fluid pressure pushes the sealing lip (surface) out and gently presses the metal surface to produce a very excellent sealing effect. The actuation effect of the spring can overcome the slight eccentricity of the metal mating surface and the wear of the sealing lip, and continue to maintain the expected sealing performance. The existing sealing environment is relatively harsh, and the spring is usually prone to damage, the service life is not long, and the replacement cost is high, which has brought certain adverse effects to people's use process. For this reason, we propose a double-sided double-spring pan-seal. Summary of the invention

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0015] This embodiment is a double-sided double-spring flood seal.

[0016] like Figure 1-3 As shown, it includes a sealing body 1, and a buffer mechanism 2 is arranged inside the sealing body 1. The buffer mechanism 2 includes a groove 3, an elastic sheet 4, a connecting frame 5, a connecting plate 6, a guide groove 7, a guide rod 8, a first spring 9 and a second spring 10. The groove 3 is opened in the middle of the sealing body 1, and the connecting plate 6 is fixedly installed in the middle of the sealing body 1. Four groups of guide rods 8 are respectively located on both sides of the outer surfaces of the upper and lower ends of the connecting plate 6. The first spring 9 is located on the upper outer surface of the guide rod 8, and the connecting frame 5 is located on the upper outer surface of the first spring 9.

[0017] The two groups of connecting frames 5 are symmetrically arranged, and the elastic sheet 4 is located on the upper outer surface of the connecting frame 5; the two groups of guide grooves 7 are respectively opened on both sides of the lower outer surface of the connecting frame 5, and the second spring 10 is located between the connecting plate 6 and the connecting frame 5; the elastic sheet 4 and the connecting frame 5 are fixedly connected, and the connecting frame 5 is slidably connected to the guide rod 8 through the guide groove 7; the connecting frame 5 is elastically connected to the connecting plate 6 through the second spring 10, and the connecting frame 5 is elastically connected to the guide rod 8 through the first spring 9.

[0018] It should be noted that the present invention is a double-sided double-spring pan-plug seal, which provides a connecting plate 6 inside the sealing body 1 and performs elastic buffering through an elastic sheet 4. When the external pressure drives the connecting frame 5 to move, it drives the guide groove 7 to slide along the guide rod 8, and buffers under the action of the first spring 9 and the second spring 10, which can facilitate elastic buffering and improve the service life of the sealing body 1.

[0019] It should be noted that, in this article, relational terms such as first and second (number one, number two), etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
