Abstract
An orifice controlled ball check valve is composed of valve body, valve cover, press ring of valve cover, elastic compression rubber pad, ball lever and ball. Its advantages are simple structure, high sealing performance, flexible and automatic control of water level, and easy use and maintenance.
Description
The present invention relates to a kind of novel floating-ball stop valve of controlling the water container water level.
Ball check valve is the vitals that is widely used in controlling the water container water level.Existing polytype is on sale on the China market now.For improving and optimizating the structure of stop valve, national valve industry all has many inventions that improve preferably, the application that has patent.The outstanding Kunming energy-efficient instrument factory technician Chang Rongsheng that has carried out a series of improvement to ball check valve, and declared multinomial patent, nearest " little latus rectum controlling type ball check valve " (application number: 96243623.2 by Patent Office of the People's Republic of China's approval, the 75th page of No. the 19th, utility model patent communique the 14th volume, May 13 98 year day for announcing), the characteristics of this stop valve are that structure is more simple in structure than the commercially available prod before the applying date at that time, good manufacturability, particularly can adopt engineering plastics by its structure is raw material, for country saves copper material.On this basis, it is simpler that comrade Chang Rongsheng develops a kind of structure recently again, the more reasonable reliable stop valve of sealability.This stop valve subtracts piston, front connector, spring and the many places seal ring of having abandoned the manufacturing process complexity, has shortened ball lever, makes structure more reasonable compact, and cost is reduced, and obtains working life prolonging.
The objective of the invention is, a kind of structure advantages of simple more is provided, number of components still less, sealability is better, is convenient to install and use the novel cutoff valve of more reliable performance more.
The present invention is achieved in that project " little latus rectum controlling type the ball check valve " (application number: 96243623.2) carried out following important structure and improved that the inventor has also authorized for original application; Subtract and abandoned front connector, piston, spring and change and reduced sealing means.Traditional lever mode of closing is improved to the automatic supercharging of pressure of supply water closes into water.Its structure and working principle are summarized as follows:
Make an orifice controlled ball check valve, in original valve body (2), valve gap (5), ball lever (9), on the ball float critical piece bases such as (10), in valve body (2), be provided with an elasticity supercharging rubber cushion (15) that current are passed through, when water is discontented with, ball float (10) is sagging, valve is in opening state, the press water that enter this moment from water intake (1), flow into container from flow-guiding mouth (17) through water outlet (18) in a large number, meanwhile, less amount press water is arranged by pressurized hole (16) and overflow hole (6) water filling in container, after water level increases, ball float floats, according to same inventive concept, can adopt overflow piece or the resistance of sliding of rotation resistance to overflow that any one mode realizes sealing overflow hole (6) in the piece, so entering the water in supercharging storehouse (3) from pressurized hole (16) constantly increases, under the hydraulic action that increases, the elasticity supercharging rubber cushion of being made by rubber (15) is pushed away forward, until the end face of sealing flow-guiding mouth (17) tightly, water can not be flowed out from flow-guiding mouth (17) again, promptly realized closing the into effect of water; If the drawdown in the container, ball float falls, then overflow hole is open-minded again, the high pressure water that Central Plains, supercharging storehouse (3) is closed is able to the earial drainage pressure release, elasticity supercharging rubber cushion (15) is under intake pressure promotes, no longer compress water conservancy diversion aperture (17) and enter the interior water of valve body, again can be through osculum to the container water filling.
Patent " little latus rectum controlling type ball check valve " was developed and declared to structure of the present invention, performance characteristics and inventor oneself originally and various ball check valves on sale are in the market compared, have that number of components is few, simple and direct rationally, the parts production technology is good, be easy to produce, good seal performance, use easy to maintenance, a plurality of advantages such as automatic control water level flexibility and reliability, a good product really.
Below in conjunction with accompanying drawing, two technical application schemes of the same inventive concept of the utility model are described in detail:
Figure one is one embodiment of this invention (analysing and observe) structural representation
Figure two is another embodiment of the present invention (analysing and observe) structural representations
Embodiment one, referring to figure one, make a pore type ball check valve with high-quality engineering plastics or copper material, it is by the valve body that has osculum (18) on the sidewall (2), valve gap (5), ball lever (9), ball float parts such as (10) are formed, its structural feature is as follows: be lined with the disc elasticity supercharging rubber cushion (15) that a middle part has pressurized hole (16) between the circle (13) in valve body (2) interior round platform rank and valve gap (5) convex, valve gap pressure ring (4) and valve body (2) scyewed joint, during turn, can compress elasticity supercharging rubber cushion (15) by valve gap (5), have the overflow hole (6) concentric on the protuberance of valve gap middle part with pressurized hole (16), the middle part of the excessive piece (8) of resistance is connected with pin (11) with the protuberance (12) on being located at valve gap (5), excessive piece (8) front end of resistance has a seal rubber pad (7), excessive piece (8) rearward end of resistance is connected with the ball lever (9) and the ball float (10) of short handle, when water filling made the ball float come-up, the seal rubber pad (7) of excessive piece (8) front end of resistance can be realized the sealing to overflow hole (6).Be penetrated with a cleansing pin (14) in pressurized hole (16) and overflow hole (6), the diameter of cleansing pin (14) can make current pass through less than the aperture of pressurized hole (16) and overflow (6).On water intake (1), can install filter screen (19) additional, prevent that impurity from stopping up pressurized hole (16) and overflow hole (6).Therefore, if after having installed filter screen (19) additional, also can no longer be equipped with cleansing pin (14).
Embodiment two, referring to figure two, with high-quality engineering plastics or orifice controlled ball check valve of copper material system, its working principle, inventive concept and embodiment one are identical, its most structure, parts are (as valve body (2), valve gap pressure ring (4), ball lever (9), ball float (10) etc.) also identical with embodiment one, identical point repeats no more, details are as follows for difference: the excessive piece (8) of resistance is a sliding type, place the valve gap protuberance (12) of hollow, valve gap protuberance one side has little water outlet (21), ball lever (9) one ends link to each other with ball float (10), the hook that is connected with the other end (20) inserts in the square hole of excessive piece (8) side of resistance, hook (20) is hinged on valve gap protuberance (12) lower wall by pin (11), be fixed with a seal rubber pad (7) at excessive piece (8) front end of resistance, when ball float floats, drive hook (20) and promote the excessive piece reach of resistance, can realize the sealing of seal rubber pad (7) to overflow hole (6).Glue wrist (15) with ring-shaped step is lining in valve body (2) interior round platform rank and has removed between the valve gap (5) of circle (13) in the convex.
No matter be embodiment one or embodiment two, valve gap (5) all can be made integral body with valve gap pressure ring (4), and water intake (1) locates to have the screw thread that can be connected with water pipe.
