Abstract
A kind of built-in double-flap check valve is the utility model is related to, it includes:Valve body, the runner through it is offered in the valve body;Bearing pin, the bearing pin are arranged in the runner and perpendicular with its axial line;Flap, the flap have two, and they are installed in rotation on the bearing pin and are engaged with the runner;Torsion spring, the torsion spring at least one, it is set on the bearing pin and is connected with two flaps;The built-in double-flap check valve, which has, opens and closes two states, and when it is in opening, the bearing of trend of the flap is parallel with the direction of the runner axial line;When it is closed, the direction of the bearing of trend of the flap and the runner axial line is perpendicular and the inwall of it and the valve body forms sealing pair.So the active force of current can be utilized to cause flap to open and make it that valve clack sealing surface and valve body sealing surface form sealing pair, realize the opening and closing of valve using the torsion of torsion spring.
Description
Technical field
The utility model belongs to valve field, is related to a kind of check-valves, and in particular to a kind of built-in double-flap check valve.
Background technology
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, its main function be prevent medium flow backwards,
Prevent pump and the drive motor from inverting, and vessel media is released.However, lever or chain are installed in existing check-valves
Ring, mechanical breakdown easily occurs.In addition, existing check-valves safeguard it is inconvenient, it is necessary to by whole check-valves from pipeline or line
Detected and/or safeguarded after being removed on road.The disadvantage of swing check valve is exactly to be designed using plug screw, and plug screw position is easy
Outer seepage.
The content of the invention
The purpose of the utility model be for overcome the deficiencies in the prior art and provide it is a kind of it is rational in infrastructure, easy to use, into
This low and sealed reliable built-in type high pressure check-valves.
To reach above-mentioned purpose, the technical solution adopted in the utility model is:A kind of built-in double-flap check valve, it is wrapped
Include:
Valve body, the runner through it is offered in the valve body;
Bearing pin, the bearing pin are arranged in the runner and perpendicular with its axial line;
Flap, the flap have two, and they are installed in rotation on the bearing pin and are engaged with the runner;
Torsion spring, the torsion spring at least one, it is set on the bearing pin and is connected with two flaps;
The built-in double-flap check valve, which has, opens and closes two states, described when it is in opening
The bearing of trend of flap is parallel with the direction of the runner axial line;When it is closed, the extension of the flap
Direction and the inwall formation sealing pair that the direction of the runner axial line is perpendicular and it is with the valve body.
Optimally, suspension ring are provided with the outer wall of the valve body.
Optimally, the guide pad being correspondingly arranged is fixed with the valve interior wall, the both ends of the bearing pin are installed in described
On guide pad, the both ends of the guide pad are provided with locating piece.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art:The utility model
Built-in double-flap check valve, by setting the torsion spring being connected with two flaps on bearing pin, it can so utilize current
Active force causes flap to open and make it that valve clack sealing surface and valve body sealing surface form sealing pair, realize using the torsion of torsion spring
The opening and closing of valve.
Brief description of the drawings
Accompanying drawing 1 is the front view of the built-in double-flap check valve of the utility model;
Accompanying drawing 2 is the side view of the built-in double-flap check valve of the utility model.
Embodiment
Shown embodiment is further described to the utility model below in conjunction with the accompanying drawings.
Built-in double-flap check valve as depicted in figs. 1 and 2, mainly include valve body 1, bearing pin 4, torsion spring 5 and flap 6
Deng.
Wherein, the runner 11 through it is offered in valve body 1, the edge of runner 11 is the inwall of valve body 1.Bearing pin 4
It is located in runner 11 and perpendicular with its axial line.Flap 6 has two, their semicirculars in shape and merge with the matching of runner 11 can
It is rotatably mounted on bearing pin 4 so that flap 6 is pivotally connected in valve body 1 by bearing pin 4.Torsion spring 5 at least one, its set
It is located on bearing pin 4 and is connected with two flaps 6;In the present embodiment, torsion spring 5 has two, and their intervals are set on bearing pin 4
And its two free ends are connected with two flaps 6 respectively.
The built-in double-flap check valve, which has, opens and closes two states:When it is in opening, flap 6
Bearing of trend is parallel with the direction of the axial line of runner 11;When it is closed, bearing of trend and the runner 11 of flap 6
The direction of axial line is perpendicular, and the sealing surface of its sealing surface and the inwall of valve body 1 forms sealing pair.
In the present embodiment, suspension ring 12 are provided with the outer wall of valve body 1.Leading of being correspondingly arranged is fixed with the inwall of valve body 1
To block 8 so that the both ends of bearing pin 4 are arranged on guide pad 8;The both ends of guide pad 8 are provided with locating piece 2, and it can be by fixed
Position block 2 is fixed on the inwall of valve body 1.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
