Abstract
The existing reversion-proof water sealing valve has complicated structure, high cost and short service life. The utility model relates to a reversion-proof water sealing valve which is composed of an inlet connecting tube, an outlet connecting tube, a floating ball type check valve and a water sealing box in a container, wherein the floating ball type check valve is composed of a hard floating ball, a soft sealing ring, guiding boards, a bracket and a partition board. The inlet connecting tube and the outlet connecting tube can be manufactured into a socket plugging type or a flange type according to the need of easy installation. The reversion-proof water sealing valve of the utility model uses four guiding boards to replace a valve seat of the existing reversion-proof water sealing valve, so the utility model simplifies technology, saves raw material and reduces cost. Due to the improvement on a sealing pair of the utility model, the service life of the utility model is increased from two years to fifty years.
Description
The utility model relates to valve, particularly non-return water-sealed valve
The pond (case) that every confession Drinking Water is used and the overflow pipe of industrial and mining enterprises' industrial water pond (case) all are connected with the municipal drainage pipeline.In case drainage system silts situation such as freeze up, will cause backing up of sewage, or foul smell is scurried into and polluted water; Jeopardize health, so life.Or influence is produced.Known non-return water-sealed valve, it is limited to exist complex structure, manufacturing cost height, connected mode; The sealing that soft ball float and hard sealing ring are formed pays application life short (being the modification inefficacy with 2 years only), makes pond (case) sink into to pour in down a chimney critical defect among the danger of pollution after 2 years again.
Task of the present utility model provides a kind of overflow pipe and municipal drainage pipeline connection that is used for Drinking Water pond (case) and industrial and mining enterprises' industrial water pond (case); protection pond (case) is avoided the municipal drainage system and is poured in down a chimney to scurry into foul smell and pollute; simple in structure, application life can be reach the safety and sanitation device for 50 years.
Non-return water-sealed valve of the present utility model is formed by importing and exporting adapter, float-ball type flap valve A and water seal box B, and float-ball type flap valve A is by the hard ball float, and soft sealing ring, four guide strips and four supports are formed.Wherein ball float is that hard, available plastics and metal are manufactured; Sealing ring is soft can being made by top-quality rubber, casing is left by the dividing plate grid, form water seal box B in the bottom, when overflow water is flowed through ball check valve A and water seal box B by entrance sleeve, ball float is located in and is inactive state on the support, retain the overflow water of certain depth simultaneously in the bottom, form water seal, thereby stop foul smell to be scurried into.Overflow water enters the municipal drainage system by discharge connection, when drainage system pours in down a chimney, to pour in down a chimney water and go in the casing by the pipe reverse flow by outlet, this moment, ball float relied on the buoyancy of self, rise with pouring in down a chimney the water surface, guide strip is spacing to be combined and seal channel with sealing ring by falling.Stop and pour in down a chimney the water reverse flow, compressed air formed a mattress sewage and valve port was separated this moment, and the protection valve port is not contaminated.Thereby played protection pond (case) and avoided pouring in down a chimney the effect of scurrying into foul smell and polluting.Connected mode is taken in the import and export of non-return water-sealed valve of the present utility model, can make flange form or spigot-and-socket respectively for the ease of installing.
The advantage of non-return water-sealed valve of the present utility model is that four guide strips in the casing have replaced the valve seat of known non-return water-sealed valve, has saved raw material, has simplified technology, has reduced cost, the improvement that sealing is paid.Brought up to five ten year by original 2 years application life.Not only has the good social benefit.Also exempted simultaneously the trouble and worry of pouring in down a chimney pollution.
Fig. 1 spigot-and-socket non-return water-sealed valve
Fig. 2 flange form non-return water-sealed valve schematic diagram, wherein (21) are the flange form entrance sleeve.(20) be the flange form discharge connection.
Embodiment: the spigot-and-socket non-return water-sealed valve is made up of the water seal box B discharge connection (10) of entrance sleeve (1) float-ball type flap valve A casing same with it (6).Float-ball type flap valve A is by hard ball float (5), and soft water shutoff circle (2) guide strip (12) and support (13) constitute.Wherein floating bad material is a rigid plastics, and the sealing ring material is a top-quality rubber.Casing (6) is left by dividing plate (11) grid, forms water seal box B in the bottom, and all the other all are ironcasting.Entrance sleeve (1), discharge connection (10) is used bolt (4) respectively with casing, and bolt (9) connects; Packing ring (8) seals.Entrance sleeve (1), the plug on top (3) use when injecting clear water; The plug (7) of casing (6) bottom uses for blowdown or when checking water seal.
Claims (3)
1, a kind of by importing and exporting the non-return water-sealed valve that adapter (1.10 or 21.20), float-ball type flap valve A and water seal box B form, it is characterized in that ball check valve A is by hard ball float (5).Soft sealing ring (2), guide strip (12), support (13) and casing (6), dividing plate (11), water seal box B constitute.
2,, it is characterized in that the hard ball float made by rigid plastics or metal according to the non-return water-sealed valve of claim 1; Soft sealing ring is made by top-quality rubber.
