Between the outer portion medial wall of certain point and relevant position on valve block periphery；Check-valve cap have one axially through end cap,
One end central authorities of end cap offer for water inlet opening, and for water inlet opening less than interior valve block bottom surface, end cap it is another
One end axially outwardly protrudes out to form a cylindrical part, and cylindrical part periphery is socketed and interference fit with rubber check valve outer portion, tubular
Portion has one section of circumferential breach to accommodate the connecting portion, and interior valve block is opened along water inlet direction under intake pressure and leaves institute
State for the opening of water inlet or because of elastic reset to fit and close the opening for water inlet.
Preferably, the cylindrical part periphery is provided with groove and is sheathed on outside it for the outer portion of rubber check valve.
Used as further optimal way, the rubber check valve outer portion medial wall is provided with two circumferential limited posts, even
Socket part is located between two circumferential limited post inner sides, and the outer lateral extent of two circumferential limited posts is less than between the breach inner transverse
Away from.
The rubber check valve is integrated and is molded.
The check valve assembly is arranged at the external port of pump cover water inlet pipe.
This utility model arranges check-valves in pump cover water inlet pipe, and when water inlet pipe has intake pressure, current wash check-valves open
Rubber in valve block, make water enter pump chamber.And when intake pressure disappears, in rubber valve block reset close water inlet pipe, keep into
The air-tightness of water pipe opening, increases the air pressure in pump chamber, so as to promote water to discharge from drain pipe under impeller effect, it is to avoid water
The noise hovered in pump chamber and cause.
