Abstract

The utility model discloses a self return anticorrosion and antifreeze faucet, which belongs to the technical field of a water pipe part, and is used for solving the problems of poor antifreezing structure and inconvenient use in the present faucet. A round through hole with internal threads is arranged on the bottom surface of the body wall of an influent end which is positioned on the front part of the inner valve core of the faucet main body, a taper pipe with external threads is arranged on the upper attaching top of the round through hole, a ball piston which can plug and close the taper pipe is arranged in the taper pipe, and a cross blocking frame is arranged in the pipe cavity of the taper pipe which is positioned on the upper part of the ball piston. The faucet of the utility model has novel structure and convenient use, thus being suitable for matching with water pipes which are used for intermittent water application in vast rural areas, in particular to the north areas, and being provided with wide popularization and application prospect.

Description

From returning the anticorrosion antifreezing faucet of formula

Technical field

The utility model belongs to a kind of anticorrosion antifreeze water tap in the water tube component technical field.

Background technique

Water tap commonly used mainly is to be connected with valve handle in the valve body on load spool, the spool to form in our domestic water.In use, the vast rural area of intermittent water application especially, after water pipe is cut off the water, the water emptying automatically in water tap and the water pipe, its anticorrosion anti-freezing structure is poor, and this just makes troubles to water.Summer, the surface temperature height, cut off the water back water tap and institute thereof connect water emptying in time in the water pipe, usually cause the water corruption to go bad; Particularly the stratum in winter of cold area freezes and to cause on the ground water tap to freeze often even bursting by freezing is metalled run out, cause the serious waste of water resources, the method that solves has takes to wait the tap of fetching boiling water after cutting off the water to allow water be back in the under ground piping, and be mostly to adopt at water tap outer wrap thick insulation layer, the employing that has is built pond installing antifreezing faucet in underground freezing below the layer, but its measure is complicated, uses inconvenience.

Summary of the invention

In order to overcome the deficiency of prior art, solve existing poor, the awkward problem of water tap anti-freezing structure, the purpose of this utility model provides a kind of novel structure, design innovation, anticorrosion and good, the easy to use tap of resistance to frost.

The utility model addresses the above problem the technological scheme that adopts:

A kind of from returning the anticorrosion antifreezing faucet of formula, it is to be shaped on a tapped round tube hole on the feed-water end body wall bottom surface of tap main body inner spool front portion, the load top is shaped on externally threaded conical pipe on round tube hole, install the bulb stopper that energy is closed the conical pipe shutoff in the conical pipe, and the vent valve that the cross divider is formed is housed at the conical pipe tube chamber that is positioned at bulb stopper top.

Above-mentioned from returning the anticorrosion antifreezing faucet of formula, described conical pipe is connected and is inlaid with seal ring on the inboard wall of tube body of bulb stopper.

Above-mentioned described bulb stopper is preferably used the depolished glass ball, or baton round, or Stainless Steel Ball from returning the anticorrosion antifreezing faucet of formula, or plates and mould Metal Ball, and the ball of other suitable material.

When the utility model uses, this water tap is installed on the water pipe, during water supply, closes in following conical pipe shutoff of the self gravitation effect of water pressure and ball; After stopping water supply, water in the water pipe is because gravitate decline, ball in the conical pipe is subjected to the external atmosphere pressure effect by jack-up, conical pipe is opened ventilation, guaranteed accumulating water and freely returning and drop under ground piping of the inside, make water tap and institute connect the emptying in time automatically of the water of ground in the water inlet, assurance is use normally.

Because technique scheme is adopted in the utility model design, has effectively solved poor, the awkward problem of existing water tap anti-freezing structure.Show that through the test result on trial it compared with prior art has novel structure, design innovation, advantage such as anticorrosion and resistance to frost is good, and is easy to use, be applicable to that especially the water pipe of northern area intermittent water application is equipped in vast rural area, has broad prospect for its application.
