Description
Technical field
The utility model belongs to valve technology field, relates to a kind of valve sealing structure.
Background technique
Valve is accessory very common in daily life and various equipment, control medium by and block.Existing valve is varied, such as: gate valve, throttle valve, ball valve, butterfly valve, membrane valve, plunger valve, stopcock etc.
Because valve needs often to open and close, if therefore valve goes wrong and causes fluid to leak, whole pipeline may be needed there is no fluid or medium when maintenance, therefore extremely bother, therefore existing valve sealing structure is improved to being extremely necessary.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides the better valve sealing structure of a kind of sealing effect.
The purpose of this utility model realizes by following technical proposal: a kind of valve sealing structure, comprise valve body and valve seat, described valve seat has annular sealing surface one, described valve body has the sealing surface two that offset corresponding to sealing surface one, described sealing surface one is provided with annular seal groove, it is characterized in that: described seal groove rectangular in cross-section, seal ring is provided with in described seal groove, described seal ring comprises O type circle and abnormity circle, described special-shaped ring cross-section is rectangular, and abnormity circle bottom surface coordinates with seal groove bottom land and offsets, abnormity circle end face is provided with the annular positioning groove for accommodate O-shaped circle, and when described O type circle is placed in locating slot, described O type circle and sealing surface two offset, metal buffer muscle is provided with in described abnormity circle, described buffering muscle is thin plate-shaped structure and cross section is curved, buffering muscle outer arced surface is arranged towards locating slot, buffering muscle intrados is arranged towards seal groove bottom land, and the position that seal groove bottom land and two seal groove cell walls intersect is pointed at two ends corresponding to described buffering muscle cross section respectively.
Due to when O type circle is placed in locating slot, O type circle and sealing surface two offset, therefore O type circle can extrude locating slot, because buffering muscle outer arced surface is arranged towards locating slot, therefore O type circle promotes the position extension that the distortion of buffering muscle is intersected towards seal groove bottom land and two seal groove cell walls with the two ends making buffering muscle cross section corresponding indirectly, therefore abnormity circle and can reach good sealing between seal groove bottom land and seal groove cell wall, finally makes sealing surface one and sealing surface two reach better sealing.
As preferably, the two ends that described buffering muscle cross section is corresponding are respectively equipped with the endless metal bar that cross section is O shape.
Arrange metal bar to avoid cushioning two ends corresponding to muscle cross section and abnormity circle is poked cause sealing to be deteriorated.
As preferably, the described metal bar floating screed that eases up is structure as a whole.
As preferably, described abnormity circle is rubber ring.
Compared with prior art, the utility model tool has the following advantages:
Due to when O type circle is placed in locating slot, O type circle and sealing surface two offset, therefore O type circle can extrude locating slot, because buffering muscle outer arced surface is arranged towards locating slot, therefore O type circle promotes the position extension that the distortion of buffering muscle is intersected towards seal groove bottom land and two seal groove cell walls with the two ends making buffering muscle cross section corresponding indirectly, therefore abnormity circle and can reach good sealing between seal groove bottom land and seal groove cell wall, finally makes sealing surface one and sealing surface two reach better sealing.
Accompanying drawing explanation
Fig. 1 is the structural representation of seal ring in the utility model;
Fig. 2 is structural representation of the present utility model.
Coding in figure is respectively:
1, valve seat; 11, sealing surface one; 12, seal groove; 2, valve body; 21, sealing surface two; 3, seal ring; 31, O type circle; 32, abnormity circle; 33, locating slot; 34, muscle is cushioned; 35, metal bar.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this valve sealing structure, comprise valve body 2 and valve seat 1, valve seat 1 has annular sealing surface 1, valve body 2 has the sealing surface two 21 that offset corresponding to sealing surface 1, sealing surface 1 is provided with annular seal groove 12, seal groove 12 rectangular in cross-section, seal ring 3 is provided with in seal groove 12, seal ring 3 comprises O type circle 31 and abnormity circle 32, abnormity circle 32 rectangular in cross-section, and abnormity circle 32 bottom surfaces coordinate with seal groove 12 bottom land and offset, abnormity circle 32 end faces are provided with the annular positioning groove 33 for accommodate O-shaped circle 31, and when O type circle 31 is placed in locating slot 33, O type circle 31 and sealing surface 2 21 offset, metal buffer muscle 34 is provided with in abnormity circle 32, buffering muscle 34 is in thin plate-shaped structure and cross section is curved, buffering muscle 34 outer arced surface is arranged towards locating slot 33, buffering muscle 34 intrados is arranged towards seal groove 12 bottom land, and the position that seal groove 12 bottom land and two seal groove 12 cell walls intersect is pointed at two ends corresponding to buffering muscle 34 cross section respectively.
Further, cushion on two ends corresponding to muscle 34 cross section and be respectively equipped with the endless metal bar 35 that cross section is O shape.Metal bar 35 floating screed 34 that eases up is structure as a whole.Abnormity circle 32 is rubber ring.
Due to when O type circle 31 is placed in locating slot 33, O type circle 31 and sealing surface 2 21 offset, therefore O type circle 31 can extrude locating slot 33, because buffering muscle 34 outer arced surface is arranged towards locating slot 33, therefore the position extension that the two ends that O type circle 31 promotion buffering indirectly muscle 34 is out of shape to make buffering muscle 34 cross section corresponding are intersected towards seal groove 12 bottom land and two seal groove 12 cell walls, therefore abnormity circle 32 and can reach good sealing between seal groove 12 bottom land and seal groove 12 cell wall, finally makes sealing surface 1 and sealing surface 2 21 reach better sealing.
