Abstract

The utility model relates to a water saving lift valve which is arranged on a tap water pipeline. A piston which is connected with an external handle as a whole is arranged in the downwards concave valve cavity of the pipeline. The piston is arranged in the valve cavity under the actions of a compression spring and a sealing rubber film. A liquid outlet hole and a liquid outlet hole are respectively arranged on the piston, and the bottom surface of the liquid inlet hole and the bottom surface of the liquid outlet hole are respectively communicated with a liquid inlet pipeline and a liquid outlet pipeline. The utility model in which the pipelines can be automatically closed when water is cut off effectively overcomes the defect of liquid overflow. The utility model has the advantages of simple structure and convenient installation.

Description

The pipeline water-saving valve

The utility model relates to a kind of poppet valve that on flow channel for liquids, plays the switch control action.

With the tap water supply pipeline is example, and when running into time-out water supply, people because forget the valve of closing a terminal, cause tap water excessive often, bring a lot of troubles to people.For address this problem, people have adopted multiple mode, its effect is also each has something to recommend him.

Goal of the invention of the present utility model is to provide a kind of can close runner automatically when fluid pipeline stops, when preventing afterflow by the excessive pipeline water-saving valve of terminal valve.

For achieving the above object, designed its overall technical architecture of pipeline water-saving valve of the utility model is: this water-saving valve is installed on the pipeline, its major technique characteristics are that pipeline is provided with a recessed valve pocket, the compressed spring of piston and the sealed Cellophane that are connected as one with handle fall within this valve pocket, connect intake pipe and piston bottom surface, outlet conduit and piston bottom surface respectively and on piston, be respectively equipped with inlet opening and liquid outlet opening, when static, inlet opening is positioned at the sealing surface below.

Pipeline water-saving valve provided by the utility model, the carrying handle that makes progress during water supply makes on the piston and moves, and inlet opening is communicated with input duct, and liquid is gone into the fluid pipeline by the liquid outlet opening drainage after pouring in the cavity of piston bottom surface, forms afterflow.At this moment, piston keeps come-up with the force balance of pressure spring under the buoyancy of liquid effect, make input duct and fluid pipeline UNICOM all the time; When cutting off the water, the effect of piston loss of buoyance is static again the falling within the valve pocket of effect lower piston of pressure spring, by sealing surface shutoff input duct once more.Therefore, this pipeline water-saving valve can be when pipeline stops tube automatic sealing liquid body pipeline, because of forgetting the liquid spill disadvantage that valve caused of closing a terminal, reduced the wasting of resources when having overcome afterflow effectively, it is simple in structure, flexible movements are easy to use.

Describe technology contents of the present utility model in detail below with reference to accompanying drawing.

Fig. 2 is the A-A cross-sectional view of Fig. 1

As shown in the figure, the pipeline water-saving valve that present patent application is designed, it is installed on the fluid pipeline, be provided with a recessed valve pocket 9 at fluid pipeline, piston 8 combines as a whole with handle 1 by bolt 3, nut 5, packing ring 7, realize involutions by valve gap 2, between the top of piston 8 and valve gap 2, be provided with a pressure spring 4, and realize sealing by sealed Cellophane 6; On piston 8, be provided with the inlet opening 12 and the liquid outlet opening 13 that are respectively applied for bottom surface and input duct 11 and fluid pipeline 10 UNICOMs.When this pipeline water-saving valve static state closed conduct, the sealing surface 15 shutoff input duct 11 of piston 8, inlet opening 12 is positioned at the below of sealing surface 15.

In the present embodiment, for making piston 8 when moving up and down, prevent that the inlet opening 12 of piston 8 and liquid outlet opening 13 from departing from input duct 11 and fluid pipeline 10, is provided with the guide rod 16 of leading role in the both sides of piston 8.

Claims

1, a kind of water-saving valve that is installed on the water supply pipe, it is characterized in that pipeline is provided with a recessed valve pocket (9), the compressed spring of piston (8) (4), sealed Cellophane (6) effect that are fixedly connected with handle (1) fall within this valve pocket (9), inlet opening (12) on the piston (8) and liquid outlet opening (13) connect with piston (8) bottom surface, and inlet opening in the state of rest (12) is positioned at the below of sealing surface (15).

2, water-saving valve according to claim 1 is characterized in that piston (8) both sides are provided with piston operation guide rod (16).
