Abstract
The utility model discloses a kind of check valves of electric reciprocating pump, it include valve bonnet, spool and valve seat, the valve seat is fixedly connected with valve bonnet, the spool is set in valve bonnet, the spool includes sealed base and several brackets, the bracket is set to the periphery of sealed base, and to flow channels are formed above sealed base between the adjacent stent of the sealed base periphery, lateral surface and the valve bonnet inner wall of bracket are slidably matched.Liquid flow is fashionable when having, and spool rises, and liquid is flowed out from flow channels, and spool control is moved in the height stroke of valve bonnet, noise will not be caused to ring there is a situation where bounce and occurred, and in addition in maintenance, can be convenient and removes valve bonnet and repair.
Description
Technical field
The utility model relates to pump accessories field, the specifically check valve of electric reciprocating pump.
Background technique
The check valve of electric reciprocating pump be typically mounted at electric reciprocating pump into leakage fluid dram, common are spherical structure, but
Due to spherical structure core bounce when noise relatively ring, leakproofness is poor when core dropping place, and core high expensive, and maintenance is not
It is enough convenient, increase user maintenance cost.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, it is small, close that the utility model provides a kind of noise
It seals, the check valve of electric reciprocating pump easy to maintenance.
The technical solution of the utility model includes: including valve bonnet, spool and valve seat, the valve seat is fixedly connected with valve bonnet,
The spool is set in valve bonnet, and the spool includes sealed base and several brackets, and the bracket is set to sealing
The periphery of pedestal, to forming flow channels above sealed base between the adjacent stent of the sealed base periphery, bracket it is outer
Side is slidably matched with valve bonnet inner wall.
By adopting the above technical scheme, liquid flow is fashionable when having, and spool rises, and liquid is flowed out from flow channels, spool control
It is moved in the height stroke of valve bonnet, noise will not be caused to ring there is a situation where bounce and occurred, in addition in maintenance, can be convenient
Valve bonnet is removed to repair.
The further setting of the utility model: sealed base is in taper type, has angular sealing surface on the valve seat, described
The conical surface and angular sealing surface of sealed base form sealing cooperation.
Using above-mentioned further setting, the leakproofness between spool and valve seat is enhanced.
The further setting of the utility model: annulus is connected between several brackets.
Further be arranged using above-mentioned, annulus play the role of it is support bracket fastened, while be conducive to spool smoothly up and down
It is mobile.
Detailed description of the invention
Fig. 1 is the structural schematic diagram inside the utility model；
Fig. 2 is the cross-sectional view of the utility model specific embodiment；
Fig. 3 is the semi-cutaway of the utility model spool depression angle；
Wherein, valve bonnet 1, spool 2, valve seat 3, sealed base 21, bracket 22, annulus 23, angular sealing surface 31.
Specific embodiment
The check valve of electric reciprocating pump as shown in FIG. 1 to FIG. 3, includes valve bonnet 1, spool 2 and valve seat 3, valve seat 3 with
Valve bonnet 1 is fixedly connected, and spool 2 is set in valve bonnet 1, and spool 2 includes that sealed base 21 and four brackets 22, bracket 22 are set
The periphery of sealed base 21 is placed in, to forming circulation above sealed base 21 between the adjacent stent 22 of 21 periphery of sealed base
Road, lateral surface and 1 inner wall of valve bonnet of bracket 22 are slidably matched, and the top of four brackets 22 is connected by annulus 23.When there is liquid
When flowing into out of valve seat 3, it is lifted spool 2 when reaching enough fluid floies, liquid then flows between 1 inner wall of sealed base 21 and valve bonnet
It crosses 21 top of arrival sealed base and flows out valve bonnet 1 again, is i.e. liquid is flowed out from flow channels, and spool 2 is only capable of in valve bonnet 1 rising up and down
Drop movement, valve bonnet 1 limit the swing in 2 other directions of spool, and the stroke range that moves up and down of spool 2 is then controlled in valve bonnet 1
In height.
Sealed base 21 is in taper type, has angular sealing surface 31, the conical surface and inclined seal of sealed base 21 on valve seat 3
31 faces form sealing cooperation, and the two, which seals mating surface, to use soft seal or hard sealing, depending on actual liquid environment.
