By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: the cut-off modulating valve of this Novel belt check function, between described valve gap and flap, be provided with damping spring, the top of described flap is fixed with flexible rod, the bottom of described valve rod is provided with the buffer cavity that does upper and lower slippage action for flap flexible rod, in the time that the pressure of water intake in valve body is greater than the pressure of water outlet, pressure medium can be washed flap open and overcome the pressure of damping spring, make the flexible rod of flap to the top motion of valve rod buffer cavity, thereby fluid can be passed through smoothly from valve port, damping spring can be alleviated the instantaneous pressure of water intake, work to regulate current, there is energy-conservation effect, in the time that the flow of fluid changes, the pressure of the telescopic variation available buffer fluid of damping spring, make media flow constant, there is quiet effect, stop valve is closed while damming, and now, water outlet pressure can be greater than water intake pressure, compressed damping spring return, the elastic force of damping spring return and the pressure of adverse current act on flap simultaneously, make the valve port of the fast downward throttle down of flap, can effectively prevent medium counter flow, play energy-conservation effect.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment when ending modulating valve and closing;
Fig. 2 be the utility model embodiment end modulating valve open time structural representation.
Embodiment
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1 and Fig. 2, the present embodiment discloses a kind of cut-off modulating valve with check function, comprise valve body 1, valve rod 2, valve gap 3, flap 4, pressure cap 5, open valve pocket 6 and Magnetic Solution lock tube 7, described valve body is provided with water intake 11 and water outlet 12 vertically, described water intake 11 is provided with outside thread or the internal thread that can be connected with pipeline with water outlet 12, described valve body 1 is positioned at water intake 11 and is provided with valve seat 13 with the adjacent place of friendship of water outlet 12, described valve seat 13 is provided with the valve port 14 that connects medium, described valve gap 3 is located at valve body 1 top, pressure cap 5 is located at valve gap 3 tops, described flap 4 is up and down on the valve port 14 of being located at the interior described valve seat 13 of valve body 1 of folding, one end of described valve rod 2 is connected with flap 4 through pressure cap 5 and valve gap 3, between described valve gap 3 and valve rod 2, be provided with seal ring 32, described unlatching valve pocket 6 is located on the free end of valve rod 2, between described valve gap 3 and flap 4, be provided with damping spring 8, the top of described flap 4 is fixed with flexible rod 41, the bottom of described valve rod 2 is provided with the buffer cavity 21 that does upper and lower slippage action for flap 4 flexible rods 41, while needing Open valve, thereby open valve cuff ovable valve stem rotates band, ovable valve stem moves upward, make the bottom surface of valve rod and the upper surface of flap there is certain keying distance, now, in the time that the pressure of water intake in valve body is greater than the pressure of water outlet, pressure medium can be washed flap open, thereby the pressure that overcomes damping spring makes the flexible rod of flap to the top motion of valve rod buffer cavity, then make fluid pass through from valve port smoothly, damping spring can be alleviated the instantaneous pressure of water intake, work to regulate current, there is energy-conservation effect, in the time that the flow of fluid changes, the pressure of the telescopic variation available buffer fluid of damping spring, make media flow constant, there is quiet effect, in the time that valve closing dams, now, water outlet pressure can be greater than water intake pressure, compressed damping spring return, the elastic force of damping spring return and the pressure of adverse current act on flap simultaneously, make the valve port of the fast downward throttle down of flap, can effectively prevent medium counter flow, play energy-conservation effect.Between described unlatching valve pocket 6 and valve gap 3, be provided with and can limit the magnetic lock device that valve rod 2 rotations open and close, described magnetic lock device comprises four locking magnet steel 91 and four springs 92, the outer side wall of described valve gap 3 is evenly equipped with locking hole, the position in the corresponding each locking of the madial wall hole of described unlatching valve pocket 6 is respectively equipped with lockhole 61, each spring 92 is located in lockhole 61, described each locking magnet steel 91 is supported and is located between lockhole 61 and locking hole by each spring 92, described Magnetic Solution lock tube 7 is mobilizable to be sheathed on the circumferential side wall of opening valve pocket 6, the position of the corresponding each lockhole 61 of this Magnetic Solution lock tube 7 is provided with the keying magnet steel 71 contrary with interior locking magnet steel 91 magnetic of lockhole 61.While needing Open valve, Magnetic Solution lock tube 7 is sheathed on to the outer surface of opening valve pocket 6, because the keying magnet steel in Magnetic Solution lock tube is contrary with the magnetic level of locking magnet steel, utilize the principle that magnetic heteropole is inhaled mutually will lock magnet steel sucking-off locking hole, thereby overcome in the pressure retraction lockhole of spring, when in the each lockhole of each keying magnet steel retraction, open valve pocket and can be with ovable valve stem to rotate, thereby realize the object opening and closing.When Magnetic Solution lock tube is not worked while packing up, between effect meeting retraction each locking hole and lockhole of each locking magnet steel due to spring, thereby the rotation of restriction open valve cuff ovable valve stem realizes antitheft function.
Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
