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, the anti-valve rod valve that flies out 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 rod 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 rod 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 cunning for being parallel to the extension of 1 axis direction of the valve body is opened up in three open loop 3
Slot 29, at least an one end are fixed on the valve rod 1 and the other end is located in the sliding slot 29 and 29 phase of sliding slot
Anti- fly out being slidably connected and is connected to the anti-bar 27 that prevents from flying out between bar 27 and three open loop 3 of flying out and takes off bar 27
Tension spring 28 from sliding slot 29.The front end of the valve rod 10 is slidably connected in front lining 2, and front lining 2 is fixed on valve seat 7,
The compression spring worked as a buffer simultaneously for making flap 11 reset, the compression spring are equipped between the flap 11 and the back bush 15
It is sheathed on the valve rod 10, annular mounting groove, the ring is formed between the flap 11 and the valve seat 7 and valve body 1
The bracing ring 16 to offset respectively at the valve seat 7 and valve body 1 is equipped in shape mounting groove, respectively at the flap 11 and valve body 1
And the sealing ring 17 that the bracing ring 16 offsets, the trim ring 18 being set between the sealing ring 17 and the valve body 1 are described
O-shaped sealing ring is additionally provided between bracing ring 16 and the valve seat 7.Pass through bracing ring 16, sealing ring 17, trim ring 18, O-shaped sealing ring
And to effectively prevent valve seat 7, flap 11 to hit impaired for the cooperation of compression spring, and reduces work volume, improves service life of valve and close
Sealing property；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, it is described anti-to fly out bar 27 and three open loops 3 are equipped with magnetic strength for controlling 22 extension elongation of the guide plate
Answer component 23.The inclined direction of the support plate 25 and the anti-bar 27 that flies out is consistent with 22 inclined direction of the guide plate and adjacent two
There are one support plates 25 for tool between a guide plate 22.15 middle part of the back bush penetrates through, and is distributed on the outside of its rear end
The boss 26 that lateral surface extends towards 1 water outlet periphery of valve body, and the inclination angle of 26 lateral surface of underlying boss be less than be located at
The boss 26 of top.When magnetic induction component 23 detect it is described it is anti-fly out that distance increases between bar 27 and three open loops 3 when, illustrate to flow
Amount is reduced to that flow can be kept to have remained to stable rotation direction and quickly flows out, then 23 output signal control guide plate 22 of magnetic induction component
It stretches out, reduces discharge area, play gather effect, carry certain inclination angle in addition, guiding flow forms vortex type flow and improves flow
The stabilization row of flow direction prevents from forming the sinuous flow reduction flow rate of outflow, and support plate 25 is consistent with 22 inclination angle of guide plate to be risen
The effect of fixed back bush 15, moreover it is possible to play the role of pre- directing, in conjunction with boss 26,1 near exit of valve body water up and down can be balanced
The speed of stream improves the speed of the outflow of flow.
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
