Description

Rigidity valve Technical Field The invention relates to the technical field of valves, in particular to a rigidity valve. Background As shown in fig. 9, fig. 9 is a schematic structural view of a stiffness valve. The stiffness valve comprises a core iron 01, a sealing head 02, a sealing block 03, a spring 04, a mandrel 05, a valve seat 07, a coil component 08 and a sealing assembly 06, wherein the sealing assembly 06 comprises a supporting piece 061 and a rubber piece 062. The coil component 08 is powered off, under the action of the spring 04, the core iron 01 drives the mandrel 05 to move upwards, then drives the sealing block 03 to be far away from the valve port, and opens the valve port, the coil component 08 is powered on, the core iron 01 and the seal head 02 absorb each other, the core iron 01 moves downwards, and the mandrel 05 drives the sealing block 03 to be close to the valve port and seal the valve port, and then closes the rigidity valve. The seal head 02 with the structure is complex in structure, and high in processing difficulty and processing cost. Disclosure of Invention The application aims to provide a rigidity valve, which has the advantages of simpler processing of a seal head part and lower processing cost.
