Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pump seals, in particular to a diaphragm pump seal. Background Art

[0002] The diaphragm pump, also known as the embolic pump, uses the membrane in the diaphragm pump to connect the transported liquid to the piston and the pump cylinder. The left side of the diaphragm in contact with the liquid is made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances. The right side of the diaphragm is filled with water and oil. Generally, the part connecting the diaphragm pump and the pipeline is a connector, which is generally a flange connection, and the connector is connected by a flange and fixing bolts.

[0003] According to the search, Chinese patent literature, announcement number: CN216008853U, discloses a high-efficiency sealing device for a diaphragm pump connector, which reduces the gap between the flanges and increases the sealing performance by arranging a mounting block installed in the mounting groove of the first flange, arranging a metal connector, and setting a sealing ring in the metal connector to prevent the sealing ring from being squeezed and deformed, thereby increasing the compressive resistance of the connector, and arranging an elastic column and a shock-absorbing spring to cooperate. When the device vibrates, the vibration of the metal connector is transmitted to the elastic column, and the elastic column squeezes the shock-absorbing spring. The shock-absorbing spring generates elastic force under pressure, reduces the vibration force, and stabilizes the connection between the first flange and the second flange. However, since a certain degree of gap will inevitably appear at the interface of the two flanges, it is inevitable that the gap will increase due to loss during long-term use, thereby affecting the actual sealing effect. Therefore, a protective structure is needed to enhance its protective performance, so as to facilitate actual long-term use. Utility Model Content
