Embodiment 2: as shown in Figure 2, a kind of preventing autorotation of water meter control valve comprises valve seat 2, valve gap 5, valve rod 6, inlet channel 1, water outlet 11, epithelium 3, epithelium liner 4 and special-purpose valve port 10; Epithelium 3 is installed in valve seat 2 cavitys, by fixing with valve seat 2 and combining of valve gap 5 mating faces, epithelium liner 4 and epithelium 3 coaxial secure fit, special-purpose valve port 10 fastening being installed in valve seat 2 cavitys, special-purpose valve port 10 is on the same axis with the center of epithelium 3, and this axis and inlet channel 1, water outlet 11 are perpendicular.The centre of epithelium liner 4 upper-end surfaces convexes with epithelium liner guide rod 8 and is one, epithelium liner guide rod 8 is on the same axis with valve rod 6, the center, lower end surface of valve rod 6 is provided with the valve rod guide cavity 7 that matches with epithelium liner guide rod 8, and promptly epithelium liner guide rod 8 shapes and height are worked in coordination with valve rod guide cavity 7 shapes and the degree of depth on the valve rod 6.Be provided with relief hole 9 on the epithelium liner 4 on epithelium liner guide rod 8 sides, relief hole 9 can be one or more.When special-purpose valve port 10 employing permeability magnetic materials, epithelium 3 or epithelium liner 4 can adopt magnetic material; When special-purpose valve port 10 employing magnetic materials, epithelium liner 4 can adopt permeability magnetic material; Special-purpose valve port 10 can adopt the opposite magnetic material of magnetic field polarity to make with epithelium 3 or epithelium liner 4; Special-purpose valve port 10 also can adopt the opposite magnetic material of magnetic field polarity to make with epithelium 3 and epithelium liner 4.
The utility model working principle is: dextrorotation rotating valve rod 6, make valve rod 6 down motion under the guiding of threaded stem, epithelium liner 4 is also done to move in the same way under epithelium liner guide rod 8 and valve rod guide cavity 7 location cooperate, and the stressed transmission by epithelium liner 4 makes sealing between epithelium 3 and the special-purpose valve port 10, valve closing.Be rotated counterclockwise valve rod 6, make valve rod 6 under the guiding of threaded stem, rise to highest order.At this moment, if the user is water not: the hydraulic pressure that reaches in epithelium 3 epicoeles in hydraulic pressure in the valve water outlet 11 and the inlet channel 1 equates, magnetic field suction between epithelium 3 or epithelium liner 4 and the special-purpose valve port 10 adds under the effect of epithelial membrane 3 and epithelium liner 4 both self gravitations, be in sealing state between epithelium 3 and the special-purpose valve port 10, the pressure reduction that effectively cuts off between valve inlet channel 1 and the water outlet 11 changes, and reaches to prevent that the water meter that is connected with valve water outlet 11 from producing rotation.If the normal water of user: valve water outlet 11 by relief hole 9 be connected and epithelium 3 epicoeles in hydraulic pressure descend suddenly, the pressure reduction that epithelium 3 forms up and down overcomes the gravity that magnetic field suction between epithelium 3 or epithelium liner 4 and the special-purpose valve port 10 adds epithelial membrane 3 and epithelium liner 4 both self, epithelium 3 is up pushed away together with epithelium liner 4, so valve open.In a single day valve is opened, magnetic field suction between epithelium 3 or epithelium liner 4 and the special-purpose valve port 10 just disappears, and the gravity that the current in the valve inlet channel 1 only need definite value to overcome epithelium 3 and epithelium liner 4 both self adds epithelial membrane 3 reducing power that self warpage of back are produced that rises and gets final product.After having broken through general safety check and utilizing spring force sealing, the liquid that passes through in the valve not only will overcome intrinsic local resistance itself, also will overcome the resistance that spring force caused that becomes quadratic relationship with valve opening degree simultaneously.If user's water clock water: from the manufacturing development of water meter itself, undeniable its accuracy of manufacturing and design sensitivity are more and more higher, so be subjected to all multifactor restrictions such as water meter design principle and manufacture cost, user's water clock water and phenomenon that water meter is not counted still exist.The utility model also has the good restraining effect to water meter water clock water phenomenon, it realizes that principle is: when user's water clock water, hydraulic pressure in valve water outlet 11 and epithelium 3 epicoeles and the water meter that is connected later and the pipeline reduces gradually, As time goes on, the pressure reduction of epithelium about in the of 3 also can increase gradually, in case this pressure reduction reaches the gravity that the magnetic field suction that can overcome between epithelium 3 or epithelium liner 4 and the special-purpose valve port 10 adds epithelial membrane 3 and epithelium liner 4 both self, epithelium 3 pushes away suddenly together with epithelium liner 4, valve was opened by moment, have one current to flow through suddenly this moment between valve epithelium 3 and special-purpose valve port 10, rapidly valve is advanced, pressure balance in the water outlet, and this burst water impact acts on the water meter, make water meter rotate metering between instantaneous, this phenomenon is crossed in the kind at whole water clock water and is moved in circles, and has reached the effective inhibition to water meter water clock water phenomenon.Thereby broken through general safety check internal cause spring force and can not produce the phenomenon that stressed sudden change can't effectively suppress water meter water clock water.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
