Abstract
A seal arrangement for push-pull valve is to consist of valve body, valve plate, pressed seat, sealing seat, sealing material, fixing frame, seal rack; The valve plate of the above and below in valve body in seal rack hole is symmetrical arranged pressed seat; The corresponding valve plate preformed groove of pressed seat, the arranged outside sealing seat on trough rim edge, the groove of pressed seat and sealing seat are arranged to opening seal groove, and sealing material is set in seal groove; The reserved uniform screw of corresponding seal rack of sealing seat, arranges adjustment bolt in hole.Hold-down bolt is outside at valve body, is convenient to the adjustment of sealing; Stop material from leakage, reduce loss and the waste of material; Avoided the pollution of material from leakage to environment: because material does not leak and is convenient to, adjust, reduced the number of times of workman's cleaning and maintenance of equipment, reduce labor strength, improved working efficiency.
Description
Technical field
The utility model relates to the supporting push-pull valve of feed bin of discharge mechanism, especially a kind of seal arrangement of push-pull valve.
Background technique
Push-pull valve often and discharge mechanism or feed bin supports the use, push-pull valve divides manual, electronic, pneumatic three kinds, feed inlet and outlet has square and circular two kinds, according to the size of bore, has tens kinds of specifications, is widely used in the industries such as metallurgy, carbon element, chemical industry, building materials.The open-shut device of push-pull valve is flashboard, moving direction and the flow direction of flashboard are perpendicular, manual, electronic or manual in the situation that, flashboard can be mobile in vertical material direction, at flashboard, move within the scope of effective travel, the distance length moving with flashboard, the mouth of gate opening varies in size, and then reaches the object of the flow of controlling material.After push-pull valve is installed, because plate is movable, body is fixed, and material easily leaks material from the junction plane of valve plate and valve body, and particularly fine powder material is more serious, causes material to shed, befouling environment.In view of above-mentioned many reasons, need to improve the seal arrangement of the supporting push-pull valve of feed bin.
Model utility content
The utility model is in order to solve push-pull valve when mobile, and material easily leaks material from the junction plane of valve plate and valve body, and particularly fine powder material is more serious, causes material to shed, befouling environment; By rational design, a kind of seal arrangement of push-pull valve is provided, hold-down bolt is outside at valve body, is convenient to the adjustment of sealing; Stop material from leakage, reduce loss and the waste of material; Avoided the pollution of material from leakage to environment: because material does not leak and is convenient to, adjust, reduced the number of times of workman's cleaning and maintenance of equipment, reduce labor strength, improved working efficiency.
The utility model, in order to realize above-mentioned goal of the invention, adopts following technological scheme: a kind of seal arrangement of push-pull valve is to consist of valve body, valve plate, pressed seat, sealing seat, sealing material, fixing frame, seal rack; Valve body middle part arranges fixing frame, and fixing frame one side arranges seal rack, between fixing frame and seal rack, fixing bolt is set; Seal rack middle part reserving valve plate hole, the above and below that valve plate in valve plate seal rack hole is set in hole is symmetrical arranged pressed seat; Pressed seat one side arranges sealing seat, pressed seat form opening seal groove with sealing seat, seal groove middle part arranges sealing material; The reserved screw of corresponding seal rack of sealing seat, arranges adjustment bolt in hole.
The beneficial effects of the utility model: hold-down bolt is outside at valve body, are convenient to the adjustment of sealing; Stop material from leakage, reduce loss and the waste of material; Avoided the pollution of material from leakage to environment: because material does not leak and is convenient to, adjust, reduced the number of times of workman's cleaning and maintenance of equipment, reduce labor strength, improved working efficiency.
The utility model is at a set of seal arrangement of the junction of valve plate and valve body design and installation, stops leakage and the befouling environment of material.
(see photo) the utility model is in the junction of plate and valve body, sealing seat of design and installation on valve body, on valve plate, join a mobilizable pressed seat, between sealing seat and pressed seat, fill out sealing material (conventionally with asbestos packing or felt), the bolt of pressed seat by two ends be fixed on valve body both sides upper steel plate and be connected, when bolt compresses, crush seal material in pressed seat embedding sealing seat, make sealing material compressive strain fill up the gap between valve plate and valve body, play the effect of sealing.Growth along with service time, because the movement of valve plate can make the sealing material wearing and tearing that contact with valve plate reduce, increasing gaps, this is to adjust hold-down bolt the amount of pressed seat embedding sealing seat is strengthened, and then compressed gasketing material, be that sealing material fills up the gap between valve plate and valve body again, reach the object of sealing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is, broken section structural representation.
Fig. 2 is, side-looking partial structurtes schematic diagram.
Fig. 3 is, plan structure schematic diagram.
In Fig. 1 .2.3: valve body 1, valve plate 2, pressed seat 3, sealing seat 4, sealing material 5, fixing frame 6, seal rack 7.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in the figure; Fixing frame 6 is set in 1 valve body, and fixing frame 6 one sides arrange seal rack 7, between fixing frame 6 and seal rack 7, fixing bolt are set; Seal rack 7 middle part reserving valve plate holes, arrange valve plate 2 in hole; The valve plate 2 of the above and below in seal rack 7 holes is symmetrical arranged pressed seat 3; Corresponding valve plate 2 preformed grooves of pressed seat 3, the arranged outside sealing seat 4 on trough rim edge, the groove of pressed seat 3 and sealing seat 4 are arranged to opening seal groove, and sealing material 5 is set in seal groove; The reserved uniform screw of corresponding seal rack 7 of sealing seat 4, arranges adjustment bolt in hole.
