Description
Technical field
The utility model relates to the nonmetal sealing configuration of a kind of ball valve elastic compensating, belongs to the technical field of ball valve sealing structure.
Background technique
The nonmetal sealing of current ball valve adopts polymeric material to make valve seat more, and the plastic deformation only by valve seat itself provides minimum seal pressure, and compensates the wearing and tearing of long-term switch.The compensation sealing structure of ball and valve base chamber has in addition: 1. the compensation shape metallic leak-proof structure of spring compound body, as the scheme of publication number 102635703A model utility, the spring outwards of this scheme is coated with the elastomeric overmold layer of rubber material, in use, when spring extrusion, rubber adhesive is full of spring chamber at once, particularly for a long time by after medium influence, rubber adhesive is easily swollen distortion, this type of defect is more aobvious outstanding, cause camber of spring quantity not sufficient, the elastic force produced is inadequate, has a strong impact on compensation sealing effect; 2. the nonmetal sealing configuration of spring energy storage seal valve seat, as the scheme of publication number 103899783A model utility, the valve seat of this scheme is made up of nonmetal polymeric material seal ring and V-type eyelet, V-type eyelet is embedded in the V-type groove of nonmetal polymeric material seal ring, the seal ring assembly parts of V-type eyelet and nonmetal polymeric material adds complicated and V-type eyelet (full circle cast) the metal plate punching processed complex (non-full circle cast structural compensates uneven, and sealing effect is influenced) of die positioning structure in man-hour actual.Through above-mentioned analysis, the compensation sealing structure of known existing ball and valve base chamber exists that working life is short, sealability is unstable, cost of production is high, production and processing and assemble the problems such as complicated, not easily widely uses.
Model utility content
The purpose of this utility model is to provide the nonmetal sealing configuration of ball valve elastic compensating that a kind of sealability is high, long service life, cost of production are low.
For achieving the above object, the technological scheme that the utility model adopts is:
The nonmetal sealing configuration of a kind of ball valve elastic compensating, coordinates on the valve body that is arranged on ball sealer and valve seat, comprises valve gap, pad, elastomer; Valve gap is connected on valve body, the interior edge face of valve gap offers successively mounting groove and elastomer active chamber, and forming station terrace between mounting groove and elastomer active chamber; Valve seat and pad are arranged in mounting groove from outside to inside successively, and pad holding is between valve seat and step surface; Elastomer is arranged in elastomer active chamber, and pressurized holding bottom pad and elastomer active chamber between.
As the further setting of such scheme, described pad is metallic shim.
Described valve gap is threaded connection on valve body.
The utility model has smooth pad nonmetal valve seat is rearmounted, and this part-structure has realized the sealing of ball sealer and valve seat; After pad, set up elastomer further simultaneously, elastomer remains elastic deformation, can automatic compensating ball valve work long hours after the defect of crush deficiency that produces because of wearing and tearing, plasticity residual deformation and high temperature or other abnormal valve seat creep caused, namely solve the exception of the seal pressure deficiency between rear valve base and ball sealer of working long hours.
In a word, by improving, the sealability that the utility model improves ball valve, the stable operation improving working life, guarantee whole pipe-line system equipment, and production and processing and assembling are simply, easy to maintenance, with low cost being convenient to is promoted the use of.
The utility model can generally be applied on various ball valve.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of valve gap in Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the nonmetal sealing configuration of the utility model ball valve elastic compensating, coordinates on the valve body 1 that is arranged on ball sealer 6 and valve seat 3, specifically comprises valve gap 2, pad 4, elastomer 5.Valve gap 2 is connected on valve body 1, the interior edge face of valve gap 2 offers successively mounting groove 23 and elastomer active chamber 21, and forming station terrace 22 between mounting groove 23 and elastomer active chamber 21.Valve seat 3 and pad 4 are arranged in mounting groove 23 from outside to inside successively, and pad 4 holding is between valve seat 3 and step surface 22.Elastomer 5 is arranged in elastomer active chamber 21, and the holding of elastomer 5 pressurized bottom pad 4 and elastomer active chamber 21 between.
In the present embodiment, pad 4 is metallic shim.Valve gap 2 is threaded connection on valve body 1.
The utility model, is placed in pad 4 on the step surface 22 of valve gap 2, and is located between valve seat 3 and step surface 22 by pad 4 crushing clamp, and pad 4 is compressed ball sealer 6 together with valve seat 3, and valve seat 3 produces certain resiliently deformable and reaches sealing.Simultaneously, after assembling, elastomer 5 remains pressured state, elastomer 5 can produce certain distortion when pressured state, load force is passed to valve seat 3 by pad 4 after producing distortion by elastomer 5, realize, to the auto-compensation of sealing between valve seat 3 and ball sealer 6, guaranteeing sealability and the working life of valve.
In the utility model, elastomer 5 is metal-sheet parts that is corrosion-resistant, high/low temperature, shaping after and through Overheating Treatment and precision optical machinery processing, inner and outer surface is smooth and regular shape, thickness are even, dimensional accuracy is high; No matter be under low temperature, high temperature or normal temperature environment, uniform load force can be provided, and amount of deformation after long-time compressive strain is even, the sealing between stable compensation valve seat 3 and ball sealer 6.
In the utility model, valve seat 3, by nonmetal polymeric material compression moldings such as PTFE (teflon), Filled PTEFs (filled polytetrafluoroethylene), also can be that above-mentioned material is processed into through precision optical machinery.
In the utility model, pad 4 by metallic material through precision optical machinery finished surface is smooth and regular shape, thickness are even, dimensional accuracy is high; Effectively the load force that elastomer 5 produces can evenly be passed to valve seat 3.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
