Abstract
The utility model relates to a pneumatic ceramic double-gate valve which mainly solves the problems that a ceramic annular plate cannot be closely attached to ceramic valve seats in an existing pneumatic ceramic double-gate valve, so that the sealing effect is poor, and the pressure bearing ability is low. The pneumatic ceramic double-gate valve is characterized in that two supporting pillars (10) are installed at the two ends of a spring (9) respectively, the outer side of each supporting pillar (10) contains a steel ball (11) which rolls freely, and the steel balls (11) on the two supporting pillars (10) abut against the center of a left plate body (3) and the center of a right plate body (4) respectively. According to the pneumatic ceramic double-gate valve, since the steel balls are additionally arranged on the supporting pillars, the supporting pillars are prevented from being jammed by the left plate body and the right plate body, the ceramic annular plate is more closely attached to the left ceramic valve seat and the right ceramic valve seat, the sealing effect is good, and the pressure bearing ability is high.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of pneumatic ceramic double flap valve.
Background technique
The open-shut device of gate valve is flashboard, and moving direction and the flow direction of flashboard are perpendicular, and gate valve can only be made standard-sized sheet and complete shut-down.In order to adapt to bad working environments, in recent years, the equal Ceramics materials processing of flashboard and valve seat, makes flashboard and valve seat all have the performances such as good resistance to chemical attack, wear-resistant, high temperature resistant, resistance to erosion, and this gate valve is referred to as ceramic gate valve.Existing pneumatic ceramic double flap valve is mainly by cylinder, valve body, valve rod, double-surface ceramics flashboard assembly, left ceramic valve seat and right ceramic valve seat composition, double-surface ceramics flashboard assembly is by left plate body, right panel body and ceramic ring flat-plate composition, the exterior edge face of left plate body and right panel body is ceramic embedded ring flat-plate all, the ceramic ring flat-plate of double-surface ceramics flashboard assembly both sides is corresponding with left ceramic valve seat and right ceramic valve seat respectively, left plate body and right panel body are arranged on support, support is provided with center hole, be built-in with spring and fore-set at center hole, in use, fore-set and left plate body, between right panel body, easily there is blocked portion, make unbalance stress between ceramic ring flat-plate and left ceramic valve seat and right ceramic valve seat, exist between ceramic ring flat-plate and ceramic valve seat and can not fit tightly, the problem that sealing effect is poor and bearing capacity is low.
Model utility content
The deficiency of can not fit tightly in order to overcome between ceramic ring flat-plate in existing pneumatic ceramic double flap valve and ceramic valve seat, sealing effect is poor and bearing capacity is low, the utility model provides a kind of pneumatic ceramic double flap valve, this pneumatic ceramic double flap valve has increased steel ball on fore-set, fore-set and left plate body, right panel body phase jam are avoided, make to fit between ceramic ring flat-plate and left and right ceramic valve seat tightr, good sealing effect, bearing capacity is high.
The technical solution of the utility model is: a kind of pneumatic ceramic double flap valve, comprise valve body and double-surface ceramics flashboard assembly, double-surface ceramics flashboard assembly is by left plate body, right panel body and ceramic ring flat-plate composition, the exterior edge face of left plate body and right panel body is ceramic embedded ring flat-plate all, the ceramic ring flat-plate of double-surface ceramics flashboard assembly both sides is corresponding with left ceramic valve seat and right ceramic valve seat respectively, left plate body and right panel body are arranged on support, support is provided with center hole, be built-in with spring and fore-set at center hole, fore-set is two and is contained in respectively the two ends of spring, the outside of fore-set includes free rolling steel ball, steel ball on two fore-sets respectively with left plate body, the center of right panel body compresses mutually.
Described left plate body, the center of right panel body are provided with the spheroidal groove matching with steel ball.
The utlity model has following beneficial effect: owing to taking such scheme, steel ball energy Free-rolling, fore-set and left plate body, right panel body phase jam are avoided, make between the ceramic ring flat-plate of double-surface ceramics flashboard assembly both sides and left ceramic valve seat and right ceramic valve seat laminating tightr, good sealing effect, stressed even between pottery ring flat-plate and left ceramic valve seat and right ceramic valve seat, bearing capacity is high.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is A place enlarged views in Fig. 1.
1-valve body in figure, 2-double-surface ceramics flashboard assembly, the left plate body of 3-, 4-right panel body, 5-pottery ring flat-plate, the left ceramic valve seat of 6-, the right ceramic valve seat of 7-, 8-support, 9-spring, 10-fore-set, 11-steel ball, 12-groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Fig. 2, a kind of pneumatic ceramic double flap valve, comprise valve body 1 and double-surface ceramics flashboard assembly 2, double-surface ceramics flashboard assembly 2 is by left plate body 3, right panel body 4 and ceramic ring flat-plate 5 form, the exterior edge face of left plate body 3 and right panel body 4 is ceramic embedded ring flat-plate 5 all, the ceramic ring flat-plate 5 of double-surface ceramics flashboard assembly 2 both sides is corresponding with left ceramic valve seat 6 and right ceramic valve seat 7 respectively, left plate body 3 and right panel body 4 are arranged on support 8, support 8 is provided with center hole, be built-in with spring 9 and fore-set 10 at center hole, fore-set 10 is two and is contained in respectively the two ends of spring 9, the outside of fore-set 10 includes free rolling steel ball 11, steel ball 11 on two fore-sets 10 respectively with left plate body 3, the center of right panel body 4 compresses mutually.Owing to taking technique scheme, in use, steel ball 11 energy Free-rollings, fore-set 10 and left plate body 3, right panel body 4 phase jams are avoided, make between the ceramic ring flat-plate 5 of double-surface ceramics flashboard assembly 2 both sides and left ceramic valve seat 6 and right ceramic valve seat 7 laminating tightr, good sealing effect, stressed even between ceramic ring flat-plate 5 and left ceramic valve seat 6 and right ceramic valve seat 7, bearing capacity is high.
Described left plate body 3, the center of right panel body 4 are provided with the spheroidal groove 12 matching with steel ball 11.Spheroidal groove 12 plays the role of positioning, and makes steel ball 11 center in left plate body 3, right panel body 4 all the time.
