A kind of venturi type self-priming valve, it comprises valve body and spool, wherein, described valve body adopts three-way valve body, it comprises the first import for connecing pressure port, for the second import of connected tank inlet line and the outlet for connecing heat sink inlet, described spool is fixed on described first import by black box, the intersection of the second import and outlet, and the fluid passage described spool is provided with for being communicated with the first import and outlet, damped part is provided with in described fluid passage, described damped part offers the damping hole that at least one is less than fluid passage diameter, described spool offers the radial hole for making the second import be connected with fluid passage along the first import to Way out in the rear end of described damped part.
Especially, described damped part is the damping mat be fixed on by fixing back-up ring in described fluid passage, and the center of described damping mat offers a damping hole.
Especially, described damped part is an independent damping plug arranged, and described damping plug is fixed in described fluid passage by worm structure, and the center of described damping plug offers damping hole.
Especially, described damped part and described spool adopt integral structure, and the inwall of described spool is extended with damping baffle in fluid passage, and the center of described damping baffle forms damping hole.
Especially, the two ends of described spool are fixed in described valve body by the spacing back-up ring of spool.
Especially, described black box is the some roads seal ring be arranged between described spool outer wall and described valve interior wall.
The beneficial effects of the utility model are, compared with prior art described venturi type self-priming valve adopts Venturi principle, pressure oil from the first import through damping hole, pass through Venturi effect, negative pressure is formed in the rear end of damping hole, fuel tank inner fluid is sucked in fluid passage by the second import, after mixing with the fluid that damping hole ejects, flows to outlet.Fluid is extracted in alternative traditional motor and oil pump combination, and not only structure is simple, reduces manufacture cost; And failure rate is low, easy to maintenance, reliability is high.
