As shown in figures 1 to 6, a kind of stamping resistance valve, including valve body 1, operating mechanism 6, transmission mechanism and open-and-close mechanism 5, valve Ontology 1 is provided with fluid inlet and outlet piping 2 and fluid channel 4, and 2 inlet end and an outlet end of fluid inlet and outlet piping is provided with screw thread 3, The wrapping of 2 fluid channel 4 of fluid inlet and outlet piping, 2 input end screw thread of fluid inlet and outlet piping are matched with the pipeline thread of input fluid, 2 outlet end screw thread of fluid inlet and outlet piping is matched with the pipeline thread of output fluid；Transmission mechanism 7 is held including rotary shaft 7, pressure resistance Row mechanism 8 and connecting screw 9,7 one end of rotary shaft are connected with operating mechanism 6, and the other end is connected with resistance to pressure actuator 8, connection 9 one end of screw rod is connected with resistance to pressure actuator 8, and the other end is connected with open-and-close mechanism 5.

Resistance to pressure actuator 8 is arranged between operating mechanism 6, transmission mechanism 7 and open-and-close mechanism 5, by limiting opening-closing machine The speed that structure 5 opens and closes realizes the huge pressure difference due to caused by quickly opening or closing, so as to avoid because huge Damage caused by big pressure difference to valve and pipe-line equipment, reduces the occurrence probability of fluid leakage.

Allowed by the open and close of open-and-close mechanism 5, limit or prevent fluid by stamping resistance valve, in use, passing through The operation of operating mechanism 6, open-and-close mechanism 5 protrude into or detach fluid channel 4 by rising or falling, thus by fluid truncation or Connection, to complete opening or closing for stamping resistance valve.

It further illustrates, in one embodiment of the utility model, resistance to pressure actuator 8 includes 81 He of driving gear Driven gear 82, driving gear 81 are connected with rotary shaft 7, and driven gear 82 is connected with connecting screw 9, and driving gear 81 is small tooth Wheel, driven gear 82 are gear wheel.The two gears are driven by the rotation of transmission mechanism 7, and make open-and-close mechanism 5 at it in turn It opens and closes and is translated between position.By the gear ratio between setting driving gear 81 and driven gear 82, subtract to reach The purpose of speed.

The difference of gear ratio between driving gear 81 and driven gear 82, operating mechanism 6 need multiple complete rotation with Rotary drive gear 82 passes through a circle.In the prior art of no resistance to pressure actuator 8, each complete rotation of operating mechanism 6 Turn a complete rotation of connecting screw 9 and the transverse translation of subsequent open-and-close mechanism 5.And there is resistance to pressure actuator 8 In the case of, each complete rotation of operating mechanism 6 leads to the complete rotation of driving gear 81, but an only small portion of driven gear 82 Divide rotation.Therefore, operating mechanism 6 and driving gear 81 must the fully rotating number for being greater than one times, can just make driven gear 82 Rotation it is primary.It will be understood by those skilled in the art that the relative size of driving gear 81 and driven gear 82 can be according to operation Mechanism 6 needs how much to enclose to change and select, so that 9 complete rotation one of connecting screw is enclosed.In this way multiplied by 6 institute of operating mechanism The number of turns needed is so as to the mobile open-and-close mechanism 5 of connecting screw 9, even if 6 maloperation of operating mechanism, open-and-close mechanism 5 is also required to more Time opens or closes.

It further illustrates, in one embodiment of the utility model, operating mechanism 6 is handle.

It further illustrates, in one embodiment of the utility model, close mechanism 5 is slider.

It further illustrates, in one embodiment of the utility model, close mechanism 5 is gate.

It further illustrates, in one embodiment of the utility model, to mitigate the weight of gate and reducing gate Cost, gate are made of plastic material, and polyethylene can be used in plastic material, and PE, polypropylene etc., gate is substantially flat cunning Moving part can slide between the open and closed positions, to open or block fluid channel respectively.But plastic material is relatively large It is not rigid enough for fluid channel, therefore for relatively large fluid channel, gate is increased in open position and closed position Between slide during be bent and destroy gate sealing risk.Therefore, in the embodiment, sliding part includes door main body 55, door Main body 55 is made of two opposite straight sideds 51, upper surface 54, lower end surface 52 and front-back, and sliding block passes through two straight sided 51 It is slideably guided in the valve body around it, lower end surface 52 is that the first part of sliding block enters valve body, is arranged in straight sided 51 There is protrusion 53, protrusion 53 is prolonged in the both direction basically perpendicular to door main body 55 itself from corresponding edge up and down It stretches, development length 5mm-6mm can provide enough rigidity.The projection 21 matched with protrusion 53 is provided on pipeline 2, it is each A raised 53 with there are two projection 21, and two projections 21, pipeline 2, fluid channel 4 form the space 24 for accommodating protrusion 53.

It further illustrates, in one embodiment of the utility model, stamping resistance valve is applied to the body of bivalve control In system, which is made of two valves, there is fluid cushion space 101 between two valves, which is preceding valve 102 and rear valve 103, fluid Cushion space is made of buffering pipe 102 and fluid cushion channel 104, and preceding valve 102 passes through 105 control switch of rotation valve rod, after Valve 103 uses above-mentioned stamping resistance valve.

This specification is noted that the stamping resistance valve of the utility model other than being used in above-mentioned bivalve system, may be used also It to need to install the occasion of valve with respective various kinds, can be used alone, can also be used cooperatively as described above with other valves, and And the stamping resistance valve of the utility model is especially suitable for people's air defense field.

Present specification describes the example of the embodiments of the present invention, it is not meant to that these embodiments illustrate and describe All possible forms of the utility model.It should be understood that the embodiment in specification can be implemented with a variety of alternative forms.Attached drawing without It needs drawn to scale；Some features can be zoomed in or out to show the details of particular elements.Disclosed specific structure and function are thin Section is not taken by way of limitation explanation, and those skilled in the art is only instructed to implement the representative base of the utility model in a variety of forms Plinth.It will be understood to one skilled in the art that can be with one or more with reference to multiple features that either figure illustrates and describes The feature combination illustrated in other attached drawings is to form the embodiment for not yet explicitly illustrating or describing.The assemblage characteristic offer of explanation is used for The representative embodiment of typical case.However, can root with the multiple combinations of the consistent feature of introduction of the utility model and modification According to needing for specific application or implementation.
