Description
Technical field
The utility model relates to valve technology field, especially a kind of flange straight check-valves.
Background technique
Currently, existing check-valves is usually flat stifled formula structure, the material of check-valves is mainly cast iron.Existing check-valves
Usually have that valve volume is larger, intensity is not high, defect poorly sealed, intolerant to abrasion.After check-valves is using one period, by
Yu Shuizhong sundries invades the sealing of valve easy to damage, causes to leak, so that the service life of check-valves is shorter.
Utility model content
The purpose of the utility model is to provide a kind of compact-sized, good seal, the longer flange straight of service life stops
Return valve.
The purpose of this utility model is achieved by the following technical solution:
A kind of flange straight check-valves, including valve body and valve deck, valve body are equipped with inlet and outlet, and valve deck is connect with valve body,
Valve deck is located at valve body upper end, and guide sleeve is arranged below in the valve deck, and guide sleeve lower end is equipped with guide rod, is arranged with valve on guide rod
Disk, is equipped with spring between valve disc and guide sleeve, valve disc can move up and down along guide rod；The valve body import and valve outlet it
Between be equipped with partition, be provided with through-hole on partition, the annular sealing surface of the valve disc top and bulkhead through-hole periphery forms sealed connection.
As the optimal technical scheme of the utility model, the valve disc top is equipped with spherical concave surface.
As the optimal technical scheme of the utility model, strainer is equipped in the valve body import.
As the optimal technical scheme of the utility model, the axis of the valve body import is parallel to the axis of valve outlet.
As the optimal technical scheme of the utility model, the upper end of the guide sleeve is equipped with annular edge, and annular edge is located at institute
It states between valve deck and the upper surface of valve body.
As the optimal technical scheme of the utility model, sealing is additionally provided between the annular edge and the upper surface of valve body
Circle.
The beneficial effects of the utility model are: compared with the existing technology, being equipped between the utility model valve disc and guide sleeve
Spring, valve body import is interior to be equipped with strainer, can effectively prevent in sundries intrusion valve body.Guide sleeve and valve disc are by bronze processing system
At intensity is high, moves flexibly between guide sleeve and valve disc, and more resistant；It is capable of forming between valve disc and valve body good
It is tightly connected.The utility model is compact-sized, good seal, long service life.
Detailed description of the invention
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:

Connect hole, 9, strainer, 10, spring, 11, valve body import, 12, valve outlet, 41, guide rod.
Specific embodiment
As shown in Figure 1, a kind of flange straight check-valves, including valve body 1 and valve deck 2, valve body 1 are equipped with import 11 and outlet
12, valve deck 2 is connect with valve body 1, and valve deck 2 is located at 1 upper end of valve body, and guide sleeve 4 is arranged below in the valve deck 2, and 4 lower end of guide sleeve is set
There is guide rod 41, valve disc 3 is arranged on guide rod 41, spring 10 is equipped between valve disc 3 and guide sleeve 4, valve disc 3 can be along guiding
Bar 41 moves up and down；It is equipped with partition between the valve body import 11 and valve outlet 12, is provided with through-hole 5, the valve disc 3 on partition
The annular sealing surface 7 of 5 periphery of top and bulkhead through-hole, which is formed, to be tightly connected.3 top of valve disc is equipped with spherical concave surface；Valve body into
Strainer 9 is equipped in mouth 11.
In the present embodiment, the upper end of the guide sleeve 4 is equipped with annular edge, and annular edge is located at the upper of the valve deck 2 and valve body 1
Between end face, sealing ring 6 is additionally provided between annular edge and the upper surface of valve body 1.The present embodiment guide sleeve 4 and valve disc 3 be all by
Bronze is processed into, and installation connecting hole 8 is provided on the flange at 1 both ends of valve body.
Above-described embodiment is only limitted to illustrate the design of the utility model and technical characteristic, and its object is to allow the skill of this field
Art personnel understand the technical solution and embodiment of utility model, can not limit the protection scope of the utility model accordingly.It is all
It is equivalent replacement or equivalence changes according to made by technical solutions of the utility model, should all covers in the utility model claims
Within the protection scope of book.
