Description

Technical Field

[0001] The utility model specifically relates to the technical field of rubber gaskets, in particular to a combined rubber gasket. Background Art

[0002] Gaskets are mechanical seals between two objects, usually used to prevent leakage due to pressure, corrosion, and natural thermal expansion and contraction of the pipeline. Since the machined surface cannot be perfect, the use of gaskets can fill the irregularities. Gaskets are usually made of sheet materials, such as pad paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass or plastic polymers (such as polytetrafluoroethylene).

[0003] Chinese Patent Publication No. CN202120736108.2 A combined gasket; comprising an upper sealing body, a lower sealing body, a sealing rubber ring and an adhesive, the upper sealing body and the lower sealing body are both annular and the top of the lower sealing body is provided with an open annular chamber, the inner wall of the annular chamber is provided with evenly distributed female threads, the outer side of the bottom end of the upper sealing body is installed in the annular chamber of the lower sealing body and its outer side is provided with a male thread connected to the female thread matching the thread, the upper sealing body is sleeved on the outer side of the output pipe of the pump body, a filling cavity is provided inside the bottom end of the upper sealing body, an adaptive sealing rubber ring is provided in the filling cavity, the sealing rubber ring is sleeved with the outer wall of the output pipe, the top of the pump body is provided with an annular output port, the lower sealing body is provided inside the output port, the bottom end of the lower sealing body is provided with an adhesive, and the adhesive is bonded to the inner wall of the output port.

[0004] The combined gasket in the above patent is directly connected to the output pipe and the pump body through the upper sealing body and the lower sealing body respectively, and the two sealing bodies are connected by the male and female threads. In this way, when sealing, there are many joints in the above patent, and leakage is easy to occur at the joints during use. In addition, the above patent is also connected by adhesive, so the adhesive is easy to expand after drying, which makes the gap at the joint larger and cannot be effectively sealed. When the internal seal is good, the adhesive cannot expand and the connection body will be damaged;

[0005] Therefore, we provide a combined rubber gasket. In this device, two bodies are provided; the two bodies are respectively installed on both sides of the combined frame, and a mounting frame is provided on the side of the two bodies away from the combined frame. The mounting frame can effectively realize the situation that thermal expansion and contraction occur between the two connecting parts during connection, and the sealing between the two connecting parts can be effectively ensured by the expansion and contraction of the mounting frame.
