Abstract
The utility model relates to an emptying valve of a liquid pipeline. A piston cylinder, a piston, a spring and a gasket are arranged in the shell of a lower-part valve body, wherein the lower end of the piston cylinder is provided with a cushion, an internal screw and an external screw; a line device positioning tube is arranged on the piston cylinder, wherein a line push tube and a line device line tube are arranged in the line device positioning tube; a sealing ring is sheathed at the exterior of the shell of an upper-part valve body; an elastic retaining ring is arranged in a ring-shaped slot; a lower porcelain slice cushion, a lower slice, an upper slice cushion, an upper slice, a nut, a spring and a passive tube are arranged in a passive tube support; and a hose is arranged outside the upper part of the passive tube, wherein a connector is arranged in the hose and a floating ball is sheathed on the connector. The emptying valve of the liquid pipeline has the advantages of safety without hidden trouble, low manufacture cost, flexible design, simple operation and difficult damage.
Description
Technical field
The utility model relates to a kind of exhaust-valve, especially the fluid pipeline exhaust-valve.
Background technique
At present, pipe evacuation is the difficult problem in multiple industry and field always.The multiple industry that relates to fluid pipeline needs the pipe evacuation technology, especially the solar water heater industry.But most uses is electromagnetism emptying or electronic emptying.Electromagnetism exhaust-valve and electronic exhaust-valve are not just wanted electricity consumption, and their fabricating cost are very high, inconvenient operation, especially very easily damage, and working life is short.If electric leakage also can constitute a threat to the person.So solenoid valve and mortor operated valve are not extensively promoted and are used.
Summary of the invention
Have deficiency in order to overcome existing exhaust-valve, the utility model provides a kind of novel fluid pipeline exhaust-valve.This fluid pipeline exhaust-valve not only can be realized pipe evacuation, and with low cost, simple to operation.
The technological scheme that its technical problem that solves the utility model adopts is: the fluid pipeline exhaust-valve, its lower body housings has piston cylinder, piston, spring, sealing gasket, there is rubber cushion the lower end of piston cylinder, inside and outside screw, row position device positioning pipe is arranged above the piston cylinder, there is row position device ejector sleeve its inside, the capable position of device, row position pipe, the upper body shell is with seal ring outward, flexible back-up ring in its circular groove, valve shell is connected with bolt with top passive pipe holder, the lower porcelain slice rubber cushion is arranged in the passive pipe holder, lower porcelain slice, the upper porcelain slice rubber cushion, upper porcelain slice, nut, spring, passive pipe, there is sebific duct the outside, top of passive pipe, and joint is arranged in the sebific duct, be with ball float on the joint, ball float has water and water tank outward.
The piston of fluid pipeline exhaust-valve inside is under the effect of hydro-flow thrust, and piston promotes row position device ejector sleeve, and row position device ejector sleeve promotes row position device capable position pipe and passive pipe.Last lower porcelain slice also is opened simultaneously, and this moment, whole pipe communicated water spontaneous current inlet water tank fully.After the water tank topped up with water, the user stops to go up water.Ducted water is state of rest, and piston, row position device ejector sleeve are because of no longer being subjected to the thrust self-return of hydraulic pressure.Row position device capable position pipe and passive pipe fix on upper, and water tank and pipeline remain and communicate at this moment, and water is also still arranged in the pipeline.
If the user wants that with ducted water emptying the user can operate with other manually mixed water valve again and once go up water, the current of last water promote piston once more and a row position device ejector sleeve moves up.The capable position of device, row position pipe also can upwards be pushed away, and when the user stopped to go up water, the capable position of device, row position pipe entered the descending groove of row position device positioning pipe.Piston, ejector sleeve are got back to the next simultaneously.The lower porcelain slice sealing of upper porcelain slice on the passive pipe and valve shell upper end, whole pipe communicates by the center hole and the air of passive pipe.This moment, the user discharged water only, but with regard to emptying pipe.
When the user want with the water in the solar water heater water tank, the user only needed operation more once to go up water.Piston, ejector sleeve, row position device capable position pipe and passive pipe can upwards be pushed away again, and last lower porcelain slice is opened.The user stops to go up water, and normally discharging water gets final product.
When user's water finishes, operation is gone up water, is stopped to go up water once more, discharging water gets final product emptying pipe.Whole operation only needed to finish in three to five seconds.
The beneficial effects of the utility model are this fluid pipeline exhaust-valve, the no hidden danger of safety, low, the flexible design, simple to operate, not fragile of fabricating cost.
