Abstract
The utility model discloses a combined valve plate one-way valve, composed of a valve body, an oil storage chamber, an oil inlet and an oil outlet. The oil inlet is positioned at the lower end of the oil storage chamber, a valve plate and a reset spring are arranged between the oil inlet and the oil outlet, the valve plate is composed of a metal sheet and a non-metal sheet which are fixedly combined, and the reset spring is positioned below the valve plate. The utility model has the advantages of good sealing effect, long service life, etc. The utility model solves the problem of hard touch between the metallic valve plate and a valve port which is made of hard plastics; the utility model also has the advantages that the phenomenon of vapour lock for an oil pump at higher temperature can be eliminated, and the service life of the valve plate can be extended.
Description
The utility model belongs to a kind of valve.
At present, the valve block of one-way valve all is single valve metal film or nonmetal valve block in the prior art, is hard collision with contacting of valve port during valve metal film work, and it is bigger to wear and tear, and in manufacture process the processing technology of valve port and valve block is had relatively high expectations simultaneously; And the valve block of nonmetallic material its hardness when temperature is higher reduces, easily do not work phenomenon, i.e. oil pump vapour locking of generation.
The purpose of this utility model is: utilize the combination of oil resistant rubber and tinsel, action is accurately prevented the effective of reverse leakage of oil when making the work of oil pump one-way valve, and simultaneously, it is big to adapt to temperature range, reduces wearing and tearing, alleviates collision, life-saving.
The utility model is to constitute like this: it is by valve body (1), accumulator (2), filler opening (3), oil outlet (4) is formed, filler opening (3) is in the lower end of accumulator (2), to valve block (5) and Returnning spring (6) are arranged between the oil outlet (4), valve block (5) is by tinsel (7), fixed the forming of non-metal plate (8) at filler opening (3), Returnning spring (6) be in valve block (5) below.
The utility model compared with prior art has good sealing effect, advantages such as long service life.It has solved the problem of bumping firmly of valve metal film and duroplasts valve port, has eliminated the vapour locking phenomenon of oil pump when higher temperature, has prolonged the working life of valve block.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model: accumulator (2) is arranged in valve body (1), filler opening (3), oil outlet (4), filler opening (3) is in the lower end of accumulator (2), at filler opening (3) to valve block (5) and Returnning spring (6) are arranged between the oil outlet (4), valve block (5) is by tinsel (7), bonding being integral of non-metal plate (8), Returnning spring (6) be in valve block (5) below.
Claims (1)
1, a kind of combined type valve block one-way valve, it is by valve body (1), accumulator (2), filler opening (3), oil outlet (4) is formed, and it is characterized in that: filler opening (3) is in the lower end of accumulator (2), at filler opening (3) to valve block (5) and Returnning spring (6) are arranged between the oil outlet (4), valve block (5) is by tinsel (7), fixed the forming of non-metal plate (8), Returnning spring (6) be in valve block (5) below.
