Description
Technical field
The utility model is related to valve fields, and in particular to a kind of three-chip type forged steel swing check valve.
Background technology
Check-valves refers to flow in itself by medium and the valve of automatic open and close flap, and main function is to prevent medium
It flows backwards.Single-lobe check-valves has the drawback that generates sizable surge when medium reflux is dynamic, be easy to cause in valve
The abrasion of component, non-return effect reduce.
The content of the invention
To solve the above-mentioned problems, the utility model provides a kind of three-chip type forged steel swing check valve.
The technical solution of the utility model is：A kind of three-chip type forged steel swing check valve, including valve body, left connector,
Right connector, flap, valve seat, axis pin, first fluid passage, valve body fluid passage, second fluid passage, left connector and right company
Junctor is separately fixed at the left and right sides of valve body, sets first fluid passage inside left connector, right connector is internally provided with
Second fluid passage, first fluid passage, valve body fluid passage and second fluid passage are in the same horizontal position；Valve seat is installed
On left connector, the sealing surface of valve seat is vertical with valve body fluid passage, and flap is provided in valve seat, and flap rotation is set in pin
On axis, axis pin is fixed on left connector, and when flap is closed, the sealing surface of flap and the sealing surface of valve seat fit.
Further, O-ring seal is embedded on the sealing surface of the flap.
Further, O-ring seal is embedded between the valve seat and left connector.
The beneficial effects of the utility model are：The utility model with conventional swing check valve the difference is that：Valve seat
Sealing surface it is vertical with valve body fluid passage, in addition on the sealing surface of flap embedded with O-ring seal, valve seat and left connector it
Between also embedded with O-ring seal, there is good leakproofness, non-return effect is good.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the enlarged drawing of O-ring seal position.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, the present embodiment is not formed to this
The limitation of utility model.
As shown in Figure 1, a kind of three-chip type forged steel swing check valve, including valve body 1, left connector 2, right connector 3, valve
Valve 4, valve seat 5, axis pin 6, stud 7, nut 8, first fluid passage 9, valve body fluid passage 10, second fluid passage 11, bolt
12, left connector 2 is fixed on the left and right sides of valve body 1, left connection with right connector 3 by the cooperation of stud 7 and nut 8 respectively
2 inside of body sets first fluid passage 9, and right connector 3 is internally provided with second fluid passage 11, first fluid passage 9, valve body
Fluid passageway 10 is in the same horizontal position with second fluid passage 11, and when check-valves is opened, fluid passes through first fluid successively
Passage 9, valve body fluid passage 10 and second fluid passage 11.
Valve seat 5 is mounted on by bolt 12 on left connector 2, and the sealing surface 13 of valve seat 5 is vertical with valve body fluid passage 10.
Flap 4 is provided in valve seat 5, the rotation of flap 4 is set on axis pin 6, and axis pin 6 is fixed on left connector 2.When flap 4 is closed
When, the sealing surface of flap 4 fits with the sealing surface 13 of valve seat 5, and fluid can not be entered first-class by valve body fluid passage 10
In body passage 9.
To ensure better seal effect, as shown in Fig. 2, being embedded with O-ring seal 14 on the sealing surface of flap 4.Valve seat 5 with
Also O-ring seal 14 is embedded between left connector 2.
The above descriptions are merely preferred embodiments of the present invention, is not used in limitation the utility model, this field skill
Art personnel can make the utility model various modifications or equivalent substitution in the essence and protection domain of the utility model,
This modification or equivalent substitution also should be regarded as in the protection domain of technical solutions of the utility model.
