Specific implementation mode
The preferred embodiment of the invention is described in detail below in conjunction with attached drawing.
As shown in Figure 1, 2, axial flow type check valve includes valve body 1, is fixed on the pedestal in the valve body 1 by support plate 25
21, the back bush 15 that is fixed on the pedestal 21, rear end be at least partly arranged in the back bush 15 and can with it is described
The valve shaft 10 of the opposite sliding of back bush 15, is fixed on the valve at the flap 11 being mutually fixedly connected with the front end of the valve shaft 10
Matching in body 1 and with the flap 11 can be by 1 sealed separation of the valve body for two-part valve seat 7 and in valve body 1
And three open loops 3 being fixedly connected with valve seat 7, the front end of the valve shaft 10 are slidably connected in front lining 2, front lining 2 is fixed
In on valve seat 7, the pressure worked as a buffer simultaneously for making flap 11 reset is equipped between the flap 11 and the back bush 15
Spring, the compression spring sleeve are set on the valve shaft 10, and annular peace is formed between the flap 11 and the valve seat 7 and valve body 1
Tankage, the annular mounting groove is interior to be equipped with the bracing ring 16 to offset respectively at the valve seat 7 and valve body 1, respectively at the valve
The sealing ring 17 that valve 11 offsets with valve body 1 and the bracing ring 16 is set between the sealing ring 17 and the valve body 1
Trim ring 18 is additionally provided with O-shaped sealing ring between the bracing ring 16 and the valve seat 7.Pass through bracing ring 16, sealing ring 17, trim ring
18, the cooperation of O-shaped sealing ring and compression spring effectively prevent valve seat 7, flap 11 to hit impaired, and reduces work volume, improves valve
The service life of door and sealing performance；1 baffle monoblock cast of valve keeps structure more stable, sturdy and durable, stable working.
As shown in figure 3, the inner ring of 1 water outlet side of the valve body is equipped with the guide plate for guiding flow to form vortex type flow
22, the guide plate 22 is telescopic to be set in the valve body 1.Control guide plate 22 is additionally provided in the valve body 1 to stretch out or receive
The actuator 24 returned, the flap 11 and the back bush 15 are equipped with the magnetic strength for controlling 22 extension elongation of the guide plate
Answer component 23.25 inclined direction of the support plate is consistent with 22 inclined direction of the guide plate and the two neighboring guide plate 22
Between tool there are one support plate 25.15 middle part of the back bush penetrates through, and lateral surface is distributed with towards valve body 1 on the outside of its rear end
The boss 26 that water outlet periphery extends, and the inclination angle of 26 lateral surface of underlying boss is less than the boss 26 being located above.When
When magnetic induction component 23 detects that distance increases between flap 11 and back bush 15, illustrate that flow is reduced to flow can be kept to remain to
There is stable rotation direction and quickly flow out, then 23 output signal control guide plate 22 of magnetic induction component is stretched out, and reduces discharge area, is risen poly-
Hold together effect, carry certain inclination angle in addition, guiding flow forms the stabilization row that vortex type flow improves flow direction, prevents from forming unrest
Stream reduces the flow rate of outflow, and support plate 25 is consistent with 22 inclination angle of guide plate can not only to play fixed back bush 15, moreover it is possible to
Play the role of pre- directing, in conjunction with boss 26, the speed of 1 near exit of valve body or more flow can be balanced, improve the outflow of flow
Speed.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
