Abstract
Non-stuffing hygiene valve is used for food, pharmaceuticals industry.It is by clamping a parallel flashboard (3) in the middle of two valve blocks (2A, 2B) and regulating clamping force valve bonnet parts such as (5) big or small and the location by screw thread and form.Because sealing surface increases, clamping force is again greater than sealing force.So, when driving flashboard (3), handle (4) runs to pod apertures (7) and runner hole (6) when overlapping, valve opening, and when departing from fully, valve closing.No matter flashboard (3) is to stop or moving, and can both constitute a circle annular sealing strip between the valve block, and medium all can't break through clamping force and leak.
Description
The invention relates in the valve technology field invention of industry desired sanitation valve mechanisms such as food, medicine.
The sanitary condition of valves that engineering is used such as beer, beverage, dairy produce,, cosmetics, medicine, biochemical industry can directly influence its quality of product, labor intensity and people's health.
But the industrial pipeline valve can not adapt to the requirement of food, medical industry health and production process automation.As: ball valve, stop valve, gate valve, stopcock, butterfly valve, membrane valve ubiquity clean less than dead angle, hydrops pit, deleterious material make the defective that filler and the inside and outside surface of spray, flow channel shape all are difficult for cutting.At present, China is formulating technical standard and hygienic practice that a cover is fit to food, medical industry valve handling characteristics just at system's full-scale development food, medical industry hygiene valve.
The objective of the invention is to enable to adapt to the requirement of food, medical industry health for a kind of non-stuffing hygiene valve structure is provided.
The present invention is improved on the basis of existing gate valve principle.The parallel flashboard of band pod apertures and the valve block on big plane under the clamping force effect greater than sealing force, fit tightly.Because the autotelic increase of sealing plane that valve block contacts with flashboard, the clamping force that flashboard and valve block are fitted is again greater than sealing force.So, when no matter where flashboard runs to, can both constitute a circle annular sealing strip between flashboard and the valve block.No matter flashboard and valve block are stopping still in the process of operation, and medium all can't break through the clamping force of flashboard and valve block applying and leak.
The present invention not only can not form the sealing valve pocket of hydrops pit, and can save valve stem packing.The all easy cutting of various part surfaces and runner circular hole.
The concrete structure of invention is drawn by following embodiment and accompanying drawing thereof.
Fig. 1 is a kind of fast opening and closing gate valve structure sectional view that proposes according to the present invention.
Fig. 2 is to sectional view according to Fig. 1 (A-A).
Fig. 3 is a kind of ordinary construction sectional view that proposes according to the present invention.
Fig. 4 is the left view according to Fig. 3.
With reference to Fig. 1, Fig. 2, clamp the parallel flashboard (3) of a band pod apertures (7) in the middle of two circular valve seats (2A, 2B) of big sealing plane.When handle (4) drives flashboard (3) from (4A) position, when doing circumference operation arrival (4B) position around mandrel (1), valve is from pod apertures (7) and the enable possition that runner hole (6) overlap, the closed position when running to pod apertures (7) and departing from runner hole (6) fully.Valve block (2A, 2B) is realized location and degree of tightness adjusting to the clamping force of flashboard (3) by the screw thread on the valve bonnet (5).
With reference to Fig. 3, Fig. 4, clamp the parallel flashboard (3) of a band pod apertures (8) in the middle of two valve blocks (2A, 2B) of big sealing plane.Handle (1) drives Stem Mut (4) actuate valve stem (5) drive flashboard (3) and does upper and lower operation.When pod apertures (8) and valve flowing channel hole (6) when overlapping, valve opening.When pod apertures (8) departs from runner hole (6) fully, valve closing.Valve block (2A, 2B) is realized location and degree of tightness adjusting to the clamping force of flashboard (3) by nut (7).
Claims (5)
1, non-stuffing hygiene valve is the parallel flashboard that clamps a band pod apertures in the middle of two valve blocks, in the flashboard running, and when pod apertures and the coincidence of runner hole, valve opening, when pod apertures departed from the runner hole fully, valve closing is characterized in that:
(A) described two valve blocks to the clamping force of flashboard greater than sealing force,
(B) no matter clamped parallel flashboard stops or moving, and no matter where, all constitutes a circle annular sealing strip between flashboard and the valve block, and medium all can't break through clamping force and leak,
(C) at the valve bonnet that a dustproof usefulness is arranged on every side of valve block, flashboard, valve rod or handle pass valve bonnet and drive the flashboard operation.
2, valve according to claim 1, wherein a kind of feature are that flashboard is made circumference operation, fast opening and closing.
3, valve according to claim 1, wherein a kind of feature are that flashboard is done upper and lower operation, and method for opening and closing is identical with common gate valve.
4, according to claim 1,2,3 described valves, when it is characterized in that the flashboard pod apertures overlaps fully with the runner hole, formation one does not have the clear opening of pit continuously, and hole wall is smooth, can clean plug by pipeline.
5,, it is characterized in that all easy cutting in inside and outside surface of part according to claim 1,2,3 described valves.
