Abstract:
A valve and a pump (1000, 2011), wherein the valve comprises: a housing assembly (10) provided with a fluid channel (111) thereon; an opening/closing assembly (20) capable of at least partially extending into or retracting from the fluid channel (111) so as to control the flow rate of the fluid channel (111); an execution assembly (30) connected to the opening/closing assembly (20) so as to control the degree of extension or retraction of the opening/closing assembly (20); a blocking assembly (40) comprising at least one deformable body (41, 42, 1410), the deformable body (41, 42, 1410) being disposed between the opening/closing assembly (20) and the housing assembly (10) to prevent leakage of the fluid medium inside the fluid channel (111), effectively addressing the issue of potential medium leakage in the prior art due to low sealing performance of a valve.
