K pump sealing pull ring

Abstract

The invention discloses a K pump sealing pull ring which comprises a sealing pull ring body, a connecting bolt, a nut, annular side pressing plates and a pressing ring; cylindrical holes are formed in the sealing pull ring body; first springs are arranged in the cylindrical holes, close to the outer side, of the sealing pull ring body; second springs are arranged in the cylindrical holes, close to the inner side, of the sealing pull ring body; the first springs and the second springs are connected with the bottoms of the corresponding cylindrical holes through circular machine screws; the number of the annular side pressing plates is two; each annular side pressing plate is in contact connection with one end of one first spring and one end of one second spring correspondingly; the pressing ring is arranged between the two annular side pressing plates; the two ends of the pressing ring are in contact with the annular side pressing plates; a first sealing gasket is arranged on one side of each annular side pressing plate; a second sealing gasket is arranged in the pressing ring; and the rigidity of the second springs is greater than that of the first springs. The sealability of a connecting part of a K pump assembly under a vibration working condition is improved.

Description

technical field [0001] The invention belongs to the technical field of pump body connection and sealing, in particular, the invention relates to a K pump sealing ring. Background technique [0002] The current pump body assembly needs to ensure the tightness between the two assemblies. The traditional way is to add rubber sealing gaskets at the connection, and then lock the two assemblies with bolts, but the pump body is in the The continuous vibration during the working process will gradually loosen the connection of the two assemblies, resulting in poor sealing performance. It is necessary to disassemble the two assemblies to replace the rubber sealing gasket. The procedure is cumbersome and the equipment maintenance cost is high. Contents of the invention [0003] The invention provides a K pump sealing pull ring, which improves the sealing performance of the joint of the K pump assembly under the condition of vibration. [0004] In order to achieve the above object, t...
