Description

Technical Field

[0001] The utility model relates to the technical field of bolt joint sealing, in particular to a novel butterfly spring rubber sealing pad. Background Art

[0002] The new butterfly spring rubber gasket adopts a butterfly spring design inside. This design allows the gasket to produce a large elastic deformation when under pressure, thereby enhancing the sealing effect. The circular disc structure of the butterfly spring has a thickness generally greater than or equal to 10mm and a rectangular cross-section, which can provide stable support and restoring force. Some existing butterfly springs use a gasket-free method to directly tighten the bolted joints. This type of traditional butterfly spring has some problems. For example, the gasket-free method cannot provide a sealing effect, which in turn affects the sealing of the bolted joints. Workers often need to use additional mechanisms to seal the bolted joints, which greatly increases the workload of the staff. Utility Model Content

[0005] Sealing body: A through hole is arranged inside the through hole, an oblique rib groove is arranged inside the through hole, a butterfly spring is arranged inside the oblique rib groove, and the butterfly spring is connected to the sealing body by vulcanization inside the oblique rib groove, which can effectively solve the problem that traditional butterfly springs cannot provide sealing effect, improve the tightness of the bolt connection and greatly improve the sealing of the connection.

[0006] Furthermore, a support ring is fixedly connected to the upper end of the through hole, an upper limit ring is fixedly connected to the interior of the support ring, and the upper limit ring is installed in cooperation with the butterfly spring to provide upper limit protection for the butterfly spring.

[0007] Furthermore, the lower surface of the limiting ring is tightly fitted with the upper surface of the butterfly spring, and the diameter of the internal circular hole of the limiting ring is smaller than the diameter of the central circular hole of the butterfly spring, thereby achieving comprehensive protection for the upper part of the butterfly spring.

[0008] Furthermore, evenly distributed lower limit blocks are fixedly connected to the middle of the through hole, and the upper surfaces of the lower limit blocks are tightly fitted with the lower surfaces of the butterfly springs, providing lower limit protection for the butterfly springs.

[0009] Furthermore, both upper and lower ends of the sealing body are fixedly connected with isolation rings, and the height of the upper isolation ring is equal to the height of the support ring to avoid excessive contact between the bolts and the sealing gasket.

[0010] Furthermore, the distal end of the sealing body is provided with an arc surface to improve the sealing performance of the side of the bolt connection.

[0011] Furthermore, the sealing body is a rubber sealing ring, and the butterfly spring is a stainless steel butterfly spring, thereby increasing the service life of the new butterfly spring rubber sealing pad.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the new butterfly spring rubber sealing pad has the following advantages:

[0013] The disc spring and the sealing body are vulcanized together, and the screw rod of the bolt passes through the through hole. During the bolt rotation installation process, the upper limit ring provides all-round limit protection for the upper end of the disc spring, and the lower limit block provides lower limit protection for the disc spring to avoid wear of the disc spring caused by bolt rotation. At the same time, the isolation ring prevents excessive contact between the bolt and the sealing body. The arc surface design of the distal end of the sealing body facilitates the new disc spring rubber sealing gasket to enter the hole environment, and at the same time improves the sealing of the new disc spring rubber sealing gasket inside the hole environment. Then, the new disc spring rubber sealing gasket can provide sealing effect while serving as a bolt fastener. It is used as a sealing gasket to effectively solve the problem that traditional disc springs cannot provide sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS
