Description

Micropore self-closing ball check valve

The utility model 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, one nearest " little latus rectum controlling type ball check valve " by Patent Office of the People's Republic of China's approval (application number: the 75th page of No. the 19th, 96243623.2 utility model patent communiques 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 purpose of this utility model is, a kind of structure advantages of simple more is provided, and number of components still less sealability is better, is convenient to install and use the novel cutoff valve of more reliable performance more.

The utility model 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: subtracted and abandoned front connector, piston, spring and change and reduced sealing means that the inventor has also authorized for original application.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 a micropore self-closing 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.For impurity in the anti-sealing stops up pressurized hole (16) or overflow hole (6), on water intake (1), should install filter screen (19) additional, or it is less to put a diameter in pressurized hole (16), the cleansing pin (14) that the part press water is flow through.For reducing preparation process, valve body pressure ring (4) can be made into an integral body with valve gap (5).

Patent " little latus rectum controlling type ball check valve " was developed and declared to the utility model structure, 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.
