Abstract
The utility model discloses a kind of good axial flow type check valves of sealing effect, it include valve body, and it is installed on the intracorporal valve seat of valve, and front end snaps into the flap in valve seat, and it is inserted in the spring in the middle part of flap, and it is inserted in the guide sleeve at flap rear portion, and it is coated at the bracket at flap rear portion, the flap is cone setting close to one end of valve seat and the rear part is cylindrical setting, the flap and valve body sealing surface cooperate, and the axial straight trough for penetrating through its top and bottom is equipped at the back cylindrical of the flap；The good axial flow type check valve of the sealing effect will not influence flow of media, and result in blockage.
Description
Technical field
A kind of the utility model axial flow type check valve good more particularly to sealing effect.
Background technique
Check-valves refers to opening and closing element for round flap and by own wt and pressure medium generation movement to block medium to fall
A kind of valve of stream.Belong to automatic valve class, also known as non-return valve, check valve, return valve or isolating valve.Flap motion mode is divided into lifting
Formula and swing type.Lift check valve is similar with stop valve structure, only lacks the valve rod for driving flap.Medium from input end (under
Side) it flows into, it is flowed out from outlet end (upside).When inlet pressure is greater than the sum of flap weight and its flow resistance, valve is opened
It opens.Conversely, valve is then closed when medium is flow backwards.Swing check valve has a flap that is tilting and being pivoted, and work is former
It manages similar to lift check valve.Check-valves is commonly used for the bottom valve of water plug, can prevent the reflux of water.
Existing check-valves is mostly to be bonded to form sealing with valve body inner face by steel ball, poor sealing performance, and due to steel ball
Gap between valve body is smaller, affects the circulation of medium, be easy to cause blocking.
Utility model content
The technical problem to be solved by the present invention is to provide one kind will not influence flow of media, and the sealing to result in blockage
The good axial flow type check valve of effect.
To solve the above problems, the utility model adopts the following technical solution:
A kind of axial flow type check valve that sealing effect is good, includes valve body, and is installed on the intracorporal valve seat of valve and front end card
Enter the flap in valve seat, and be inserted in the spring in the middle part of flap, and is inserted in the guide sleeve at flap rear portion, and be coated at flap
The bracket at rear portion, the flap is cone setting close to one end of valve seat and the rear part is cylindrical setting, the flap with
Valve body sealing surface cooperates, and the axial straight trough for penetrating through its top and bottom is equipped at the back cylindrical of the flap.
Preferably, the axial direction straight trough is equipped with more than two and is placed equidistant with along the periphery of flap.
Preferably, the cross section of the axial direction straight trough is arc-shaped setting.
Preferably, the bracket is equipped with a side to screw hole, the lateral screw hole is connected to guide sleeve and and guide sleeve
It is perpendicular.
Preferably, screwing in the lateral screw hole has screw, the screw offsets with guide sleeve.
The utility model has the following beneficial effects: the flap designed by conical surface seal, keeps the sealing surface of valve seat wider, improve
The sealing reliability of check-valves increases the circulation area of medium by being uniformly distributed a plurality of straight trough at the circumference of flap,
Improve the flow of media ability of check-valves.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the good axial flow type check valve of sealing effect of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, so that the utility model technology
Scheme is more readily understood and grasps.
As shown in Figure 1, the axial flow type check valve that a kind of sealing effect is good, includes valve body 1, and be installed in valve body 1
Valve seat 2 and front end snap into the flap 3 in valve seat 2, and are inserted in the spring 4 at 3 middle part of flap, and be inserted in 3 rear portion of flap
Guide sleeve 5, and be coated at the bracket 6 at 3 rear portion of flap, the flap 3 are cone setting and thereafter close to one end of valve seat 2
Portion is cylindrical setting, and the flap 3 cooperates with 1 sealing surface of valve body, is equipped at the back cylindrical of the flap 3 and penetrates through its top
The axial straight trough 7 in face and bottom surface, the axial direction straight trough 7 are equipped with more than two and are placed equidistant with along the periphery of flap 3, the axis
It is arc-shaped setting to the cross section of straight trough 7, the bracket 6 is equipped with a side to screw hole 8, the lateral screw hole 8 and guide sleeve 5
It is connected to and perpendicular with guide sleeve 5, screwing in the lateral screw hole 8 has screw 9, and the screw 9 offsets with guide sleeve 5.
Operation instruction:
The flap 3 of conical surface seal design improves the sealing surface of valve seat 2, its width is made to be improved, and cooperates the conical surface
The axial straight trough 7 of Seal Design, then improve by fluid media (medium) circulation area so that the check-valves had obtained
The raising of sealing reliability and the extension of service life, it is economic and practical.
The utility model has the following beneficial effects: the flap designed by conical surface seal, keeps the sealing surface of valve seat wider, improve
The sealing reliability of check-valves increases the circulation area of medium by being uniformly distributed a plurality of straight trough at the circumference of flap,
Improve the flow of media ability of check-valves.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
