structure tomography radially and axially on inner ring surface is formed, structure tomography can be used in buffering double caused by water hammer effect To repeated stock, it also can be used in the axial compressive force change that cushion seal ring 6 is subject to；The axial direction of sealing ring 6 is become simultaneously Shape and radial deformation are construed as limiting, and avoid sealing ring 6 due to deforming phenomenon that is excessive and falling off, so as to ensure overall knot The stability of structure.Alternatively, seal ring 6 and/or bracing ring uses silica gel ring or rubber ring.The cross sectional shape of bracing ring is One kind in L-shaped, T-shaped, U-shaped.The bracing ring of different structure form can be selected as needed to meet requirement.L-shaped Bracing ring is formed to the axially unidirectional barrier on the limitation and inner ring surface surface limitation of sealing ring 6.The bracing ring of T-shaped is formed to close The axially two-way barrier on the limitation and inner ring surface surface limitation of seal ring circle 6.The bracing ring of U-shaped is formed to 6 pairs of positions of sealing ring The axially overall barrier on limitation and inner ring surface surface limitation.Bracing ring includes being used for the build-in portion being mounted in inner ring surface wall body And it is attached at the attaching portion on inner ring surface surface.Alternatively, attaching portion is resisted against the end of still 201 towards one end of first end face Face.Alternatively, attaching portion leaves spacing towards between one end of first end face and still 201.By build-in portion build-in in inner ring In the surface groove of face, to form limitation and the axial buffer function to sealing the axial deformation of ring 6.It is attached to by attaching portion Inner ring surface surface, the radial deformation and buffering radial forces of ring 6 are sealed with limitation.Seal ring 6 first end face and/ Or the second end face of sealing ring 6 is provided with and is used in contact contact process buffer contact active force by compression and seals The hermetic seal ring of sealing；And/or second end face is provided with to be used to being mounted in the inner chamber of valve body 1 to encorbelment and sealing is formed in step 104 The build-in bulge loop of ring.The cross sectional shape of build-in bulge loop is at least one of rectangle, taper, triangle, U-shaped.Can be according to need Different build-in bulge loop cross sectional shapes is selected, surface taper can facilitate structure assembly in place.Alternatively, the water inlet connection mouth of pipe 101 coaxially lay with installation opening 103.Alternatively, the radial dimension of valve body 1 connects the mouth of pipe 101 to the direction of installation opening 103 from water inlet Gradually increase, or valve body 1 is the isometrical tubular structure of radial dimension identical.Alternatively, the radial cross-sectional shape of valve body 1 is circle Shape, ellipse, rectangle or trapezoidal.Alternatively, the end face that fastener 203 is used to contact with the gluing, sealing of moving plate 202 is bright for minute surface The primary sealing area of degree.Correspondingly, the end face relative with primary sealing area of moving plate 202 uses the secondary sealing area of specular brightness. Fastener 203 is bonded and is in close contact with moving plate 202, is passed through with preventing and obstructing current.Alternatively, ring 6 and/or branch are sealed Support ring uses silica gel ring or rubber ring.Alternatively, sealing ring 6 be held on the lateral wall of still 201 and the madial wall of valve body 1 it Between, and/or the sealing build-in of ring 6 is in the embedded slot between the lateral wall of still 201 and the madial wall of valve body 1.Can be according to valve body 1 Inner-cavity structure, current circulation passage distribution situation and water route regulation require, different sealing means are selected, to ensure current only It can be flowed by the fixation flow channel transmission of still 201, effectively avoid current leakage problems.And using still 201 with The mode that step 104 radially clamps of encorbelmenting lays sealing ring 6, and the radial stability for sealing ring 6 is good and true by chucking power Confidential letter ring 6 is axially stable, and the flowing current passed through will not directly impact sealing ring 6, the influence to sealing ring 6 Small, sealing ring 6 will not produce displacement, therefore can ensure to seal the sealing effectiveness of ring 6, it is ensured that still 201 and valve body 1 it Between will not seepage.Sealing ring 6 is held on the bottom surface of still 201 between the upper surface of step 104 of encorbelmenting, and/or sealing ring 6 Build-in is in the embedded slot between the bottom surface of still 201 and the upper surface of step 104 of encorbelmenting.Can be according to the inner-cavity structure of valve body 1, water Flow circulation passage distribution situation and water route regulation requires, different sealing means are selected, to ensure that current only can be by quiet The fixation flow channel transmission flowing of piece 201, effectively avoids current leakage problems.And using still 201 and step 104 of encorbelmenting The mode clamped up and down lays sealing ring 6, and the axial stability of sealing ring 6 is good, and ensures sealing ring 6 by chucking power It is radially stable, and the flowing current passed through will not directly impact sealing ring 6, the influence to sealing ring 6 is small, seals ring 6 Displacement will not be produced, therefore can ensure to seal the sealing effectiveness of ring 6, it is ensured that will not seepage between still 201 and valve body 1. Alternatively, bracing ring is assemblied on the sealing wall body of ring 6 or is coated in the sealing wall body of ring 6 vertically, close so as to improve The anti-pressure ability and non-deformability of the radial direction of seal ring circle 6, it is ensured that sealing effectiveness.Gone to the bottom when sealing ring 6 is laid in still 201 When between face and the upper surface of step 104 of encorbelmenting, bracing ring is radially assemblied on the sealing wall body of ring 6 or is coated on sealing ring Enclose in 6 wall bodies, so as to improve the anti-pressure ability and non-deformability of the radial direction of sealing ring 6, it is ensured that sealing effectiveness.
