Abstract
The utility model relates to an elevation type check valve with a floating ball, which is composed of a valve body, a valve cap, a valve core, a guide track and a nozzle, wherein a branch tube of the valve body is vertically crossed with a main flow passage; a subsidiary flow passage is formed between the branch tube and the main flow passage in a penetrating mode. The spherical valve core can move up and down reliably along with the flowing state change of the fluid in the branch tube and play the check valve action. The utility model has the characteristics of superior performance, small fluid resistance, long service life, etc., because of the peculiar design.
Description
The utility model relates to the valve type in the universal pipes annex, especially relates to the float-ball type safety check in the small-bore pipeline distributing system.
Existing float-ball type safety check has H80C-10 type float-ball type safety check, H62X-10S type float-ball type safety check etc., all forms the unidirectional keying that prevents medium counter flow by valve body, valve seat, ball core, seal ring etc. and uses.Chinese patent CN87211361V improves this type of valve, this oblique floating type ball check valve is made up of valve body, spool, valve seat and pad, valve body is diagonal to valve flowing channel by arm and forms, spherical spool moves up and down with the fluid flow state variation in arm, play the non-return valve action, its advantage is that spool is kept away into the arm top when fluid flows, the minimizing of convection cell resistance; Its shortcoming is, when the sprue of valve was the level of state, spool was in enclosed arm in the uphill process, because the medium on spool top is difficult to flow, spool floats to the arm top on can not be effectively, and it is not smooth to cause fluid to flow, and resistance increases.
The purpose of this utility model provides a kind of simple in structure, and drag losses is little, the ball float Lift check valve of ball float rising reliable operation.
The ball float Lift check valve that the utility model is made up of valve body, valve gap, spool.The arm of valve body and the sprue of valve body intersect vertically, the diameter of arm is greater than the sprue diameter, spool is spherical, can in arm, roll, greater than the diameter of sprue, arm top side-walls and sprue outlet tail end are connected by a through hole diameter of spool, form secondary channels less than the diameter of arm, one nozzle is installed on the sprue, and its position is at secondary channels and sprue openings place.Valve body is the main body of valve, and the sprue in it is the passage of media flow, and arm is the activity space of spool come-up, and spool is disposed in the valve body arm by the upper end open of arm, and valve gap is used for sealing the upper end open of arm, prevents that medium runs off.Nozzle is made general shape, can be cylindrical, taper shape etc.When medium in the valve body sprue during forward flow, spherical valve core is floated in arm by medium thrust and buoyancy function, because the effect of nozzle, the pressure at the openings place of secondary channels and sprue is less than the pressure of secondary channels in arm sidewall ingress, make the interior medium of arm can waltz through secondary channels and enter sprue, thereby guarantee that effectively the spool come-up puts in place, makes the valve complete opening; When medium in the valve body sprue during reverse flow, spool is being pushed sprue under the effect of deadweight and under the medium thrust, and the main flow road junction is sealed, and valve is closed fully.
That section that sprue in the utility model valve body and arm intersect, its diameter is identical with the arm diameter, and arc-shaped rail is housed on sprue, and the guide rail two ends are tangent with branch pipe wall and sprue tube wall respectively.The diameter one that increases sprue is the activity space that has increased spool, the 2nd, and for mounting guide rail.The setting of guide rail makes spherical valve core when being subjected to bigger medium thrust, also can upwards float along guide rail to enter arm, seals sprue and be unlikely.
That section sprue caliber increases near containing nozzle mouth mouth in the utility model valve body, form cavity, when making nozzle ejection like this, the pressure effect that reduces secondary channels and sprue openings place is better, medium in the arm enters sprue by secondary channels more swimmingly, and spool more can float reliably in arm and put in place.
Materials such as valve body of the present utility model, valve gap, nozzle, guide rail, spool can be cylinder iron, carbon steel alloyed steel, copper, aluminium, plexiglass, plastics, glass fibre reinforced plastics are made, and spool can also be made with rubber, coated rubber, coated plastics etc.Above-mentioned material is according to the medium situation in source and the sprue, and that suits measures to local conditions selects for use.
The utility model is owing to designed distinctive secondary channels, nozzle etc., thereby a kind of reliable operation, superior performance are provided, the novel floating-ball formula safety check that increase working life, when keeping original this type of valve advantage, overcome its shortcoming again, after applying, will bring remarkable social benefit and economic benefit.
Fig. 1 is a longitudinal sectional view of the present utility model.
Among the figure: 1 valve body, 2 valve gaps, 3 nozzles, 4 guide rails, 5 spools
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Valve body among the figure (1) is an ironcasting, and being intersected vertically by arm and valve body sprue is that one, the internal diameter of arm are 60mm, and valve body sprue diameter is 40mm, and sprue and arm intersect vertically the diameter of that section also for 60mm.The secondary channels internal diameter is 10mm.Nozzle (3) is cylindrical, and internal diameter is 30mm, and external diameter is 40mm, matches with sprue, makes with brass.The sprue diameter at nozzle (3) mouth mouth place is 60mm, and long 40mm forms a cylindrical cavity.Spool (5) is skeleton ball, diameter 50mm.Guide rail (4) is formed from aluminium, and is board-like (thickness of slab 3mm) circular arc, and promptly plate is the approximate right angle triangle, and its hypotenuse changes circular arc into, makes itself and branch pipe wall and sprue tube wall just in time tangent.Valve gap (2) is formed from aluminium, and internal diameter is 60mm, adds gasket seal and arm sealed attachment.
