Abstract
The utility model relates to an ultra -low temperature plate valve, including valve body, disk seat, flashboard, valve rod, valve gap, mainly that sealed face of flashboard outlet side and the dual plane of outlet side disk seat constitution soft or hard are sealed vice, it is vice that sealed of flashboard intake side and intake side disk seat constitute the wedge -type seal. Having the elasticity compensation structure characteristics of wedge gate valve promptly, having the soft or hard double sealing of plate valve, the characteristics of self -cleaning sealed face structure again, have the micro -strain of the super low temperature working condition flashboard of automatic compensation, its sealing performance is reliable. Be applicable to the ultra -low temperature medium operating mode of trades such as oil, chemical industry.
Description
Technical field
The utility model belongs to valve field, particularly a kind of gate valve.The utility model is applicable to the ultralow temperature mixture condition of the industry such as oil, chemical industry.
Background technique
Existing ultra-low temperature throttle valve, mainly contains Wedge gate valve and dull and stereotyped gate valve structure.Wedge gate valve structure, under ultralow-temperature operation conditions, two sealing pairs of flashboard are all hard sealings, and after deformation, sealing surface Percent of contact area is not high, and sealing effect is bad.Plate valve structure, under ultralow-temperature operation conditions, flashboard seals by soft sealing material, and after deformation, can not get elastic compensating, sealing effect is undesirable.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, sealability reliable ultralow temperature plate valve when providing a kind of ultralow temperature to be out of shape.
The technical solution of the utility model comprises valve body, valve seat, flashboard, valve rod, valve gap, and mainly flashboard outlet side sealing surface and outlet side valve seat form the dual plane sealing pair of soft or hard, and it is secondary that flashboard suction side sealing surface and suction side valve seat form wedge-type seal.
Preferably, be shaped with relief hole inside flashboard suction side sealing surface, this relief hole is communicated with valve body inlet passage and valve body lumen when flashboard cuts out with valve seat.
Preferably, install the first lip-type packing between valve body and valve gap, this first lip-type packing is opening down, is fitted in the circular groove of cavity wall in valve body by valve gap.
Preferably, install the second lip-type packing between valve rod and valve gap, this second lip-type packing is opening down, is fitted in the circular groove in valve gap by valve rod.
The utility model has the advantages that flashboard outlet side and valve seat adopt dual plane sealing secondary, suction side is that wedge-type seal is secondary, namely the elastic compensating structure feature of Wedge gate valve is had, there are again the soft or hard double seal of plate valve, the feature of self-cleaning sealing surface structure, have the micro-strain of auto-compensation ultralow-temperature operation conditions flashboard, its sealability is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 valve body, 2 valve seats, 3 flashboards, 4 valve rods, 5 valve gaps, 6 relief holes, 7, the first lip-type packing, 8 second lip-type packings.
Embodiment
Ultralow temperature plate valve as shown in Figure 1, comprises valve body 1, valve seat 2, flashboard 3, valve rod 4, valve gap 5, and valve rod 4 lower end is fixedly connected with flashboard 3 upper-end surface, and upper end is fixedly connected with transmission handwheel through valve gap 5, installs stuffing box packing between valve rod 4 and valve gap 5; It is secondary that flashboard 3 outlet side sealing surface and outlet side valve seat form the dual plane sealing of soft or hard, it is secondary that flashboard 3 suction side sealing surface and suction side valve seat form wedge-type seal, namely there is the elastic compensating structure feature of Wedge gate valve, have again the soft or hard double seal of plate valve, the feature of self-cleaning sealing surface structure.
Be shaped with relief hole 6 inside flashboard 3 suction side sealing surface, this relief hole 6 is communicated with valve body 1 inlet passage and valve body 1 lumen when flashboard 3 cuts out with valve seat 2, and under preventing closed condition, valve body 1 lumen boosts extremely.
Between valve body 1 and valve gap 5, install the first lip-type packing 7, this first lip-type packing 7 is opening down, is fitted in the circular groove of cavity wall in valve body 1 by valve gap 5, forms the medium self-sealing structure between valve body 1 and valve gap 5.Install the second lip-type packing 8 between valve rod 4 and valve gap 5, this second lip-type packing 8 is opening down, is fitted in the circular groove in valve gap 5 by valve rod 4, forms the medium self-sealing structure between valve rod 4 and valve gap 5.
