Abstract
The invention relates to a floating ball type vent valve, which solves technical problems by adopting the technical scheme: effectively intercepting water in a cavity by using two semicircular metal sheets (made of materials the same as those of a shell); and vertically floating a stainless steel floating ball by means of buoyancy of the water, and sealing the cavity by the aid of the stainless steel floating ball and a spherical rubber surface on the upper portion of the cavity. The shell includes an upper portion and a lower portion which are connected with each other through a screw thread, and the inner surface of the shell is smooth after the two portions are connected. When water is started to be filled into a system, gas-water mixture in the system enters the vent valve, gas is separated from the water under the action of gravity, the gas moves upwards and enters the atmosphere through a vent hole, and the water downwardly enters a pipeline system through a joint. After the system reaches a certain pressure, the gas-water mixture at a certain pressure is filled in the cavity, the water is filled in the inner lower half portion of the cavity, the stainless steel floating ball (with average density is 1/4 lower than water density) can float above a water surface under the action of buoyancy, the floating ball slowly rises along with increase of water quantity ad finally contacts with the spherical rubber surface at the upper edge of the cavity, and the floating ball and the spherical surface are combined more tightly when water pressure is higher, so that vent and water plugging functions are achieved. The floating ball type vent valve has the advantages of rapidness in vent, difficulty in blocking the vent hole and durability in use.
Description
Affiliated technical field
The present invention is a kind of means of deflation that is used for small-sized water lines closed system, and simple in structure, effect is remarkable.The using effect of bleed valve directly affects the runnability of closed-circuit system, influences the using effect and the working life of water pump.
Background technique
At present, bleed valve commonly used in hot-water heating, the Air-conditioning Engineering is the pin type bleed valve, and its shortcoming is that venting is slow, and discharge quantity is little; Because vent hole is less, easy blocking.When system's water filling again moves, need the labor time at every turn, and need the artificial system's highest point of going up system exhaust.
Summary of the invention
For solving the little problem with easy blocking of discharge quantity, the vent hole of bleed valve is amplified.The present invention not only can emit gas in the system fast and effectively, and difficult obstruction durable in use.
The technical solution adopted for the present invention to solve the technical problems is: utilize two semicircle tinsels (with the same material of shell) that the water in the cavity is effectively tackled; Utilize buoyancy of water that stainless steel floating ball is fluctuated, utilize stainless steel floating ball and the spherical rubber face seal of cavity top.Shell is divided into two-part up and down, is connected by screw thread between two-part, and it is smooth that two-part connect the back internal surface.When beginning in system filled with water, Installed System Memory enters into bleed valve at air-water mixture, air-water separation under the effect of gravity, and gas moves up and gets into atmosphere through vent hole; Water gets into pipe-line system through the joint downwards, after system arrives certain pressure, has the air-water mixture under the certain pressure in the cavity; Lower half portion is a water in the cavity, under buoyancy function, can keep afloat above with stainless steel floating ball (averag density is less than 1/4 of water density); With the increase of rate of water added, ball float slowly rises, and finally touches the rubber sphere of cavity top edge; Water pressure is big more, and it is tight more that ball float combines with sphere, reaches the effect of venting and water blockoff like this.
The invention has the beneficial effects as follows, venting fast, vent hole is difficult for stopping up, and is durable in use.
