Abstract

The utility model relates to a running water pipe tap with a leather packing piston type valve. In the utility model, a leather packing piston type valve is installed in an existing running water pipe tap; a screw rod penetrates into the leather packing piston type valve; the inner screwed connection between an upper and a lower components of the running water pipe tap are in is changed into outer screwed connection; a copper pressing cap at the top end of the running water pipe tap is removed. The utility model has the advantages of simple structure, low cost, water saving and long service life.

Description

Running water pipe tap with leather collar piston type valve

The utility model relates to a kind of tap water ozzle that the leather packing piston valve is arranged, and it is the improvement of ordinary tap water ozzle.

At present, the running water pipe screw mandrel easy-to-rust that people use, packing ring is fragile, silk tooth deformation rate height, thereby the tap water ozzle life-span is short, this causes trouble to applying unit, and pain in the neck especially for numerous residents particularly is because in case the screw thread of tap water ozzle or packing ring damage, tap water ozzle then flowing water is more than, and can not find spare part for the moment, and can not find the people to repair, cause the waste of water.

The purpose of this utility model provides a kind of tap water ozzle with leather packing piston valve, and it can address the above problem effectively.

The purpose of this utility model is achieved in that it is made up of tap water ozzle lower body 1, tap water ozzle upper body 2, also have leather packing piston valve 3: leather packing piston valve 3 is made up of pad 4, cannulated threaded body 5, the end 6 and metal washer 7: pad 4 is positioned at cannulated threaded body 5 tops, be connected as a single entity, there is the end 6 cannulated threaded body 5 lower ends, place metal washer 7 at the end 6; Leather packing piston valve 3 is installed in the upper end of tap water ozzle lower body 1 water inlet and outlet passage; The top ports 8 of tap water ozzle lower body 1 has outside thread, and there is bowl bodies 9 lower end of tap water ozzle upper body 2, and its inner ring has screw thread; Top ports 8 is spirally connected with bowl bodies 9.

Because adopt such scheme, the leather packing piston valve can be protected not water contacting of screw mandrel, do not lure erosion, a tooth not fragile, thereby prolonged working life; The copper pressure cap and the inner copper washer that have removed the top are arranged again, and tube has been changed structure, has also reduced cost, and in addition, the screw mandrel top does not emit water, do not metal run out, and many a little makes a mickle can be saved a large amount of tap water.

Below in conjunction with embodiment and accompanying drawing the utility model is further specified.

Fig. 1 is the utility model embodiment sectional view.

Fig. 2 is leather packing piston valve 3 structural representations among the embodiment.

Fig. 3 is leather packing piston valve 3 plan views among the embodiment.

Among the figure: 1. tap water ozzle lower body 2. tap water ozzle upper bodies 3. leather packing piston valves, 4. pads 5. cannulated threaded bodies 6. end, 7. metal washers, 8. top ports 9. bowl bodies 10. plastic cement pads

In Fig. 1～3, the pad 4 of leather packing piston valve 3, whippy cannulated threaded body 5 are a glue injection forming with the end 6, and metal washer 7 is installed at the end 6; Whole leather packing piston valve 3 devices are on the end platform of tap water ozzle lower body 1 water inlet and outlet passage, metallic shim 7 at the end 6 guarantees that the end 6 is stabilized on the platform, do not glide, and be contained on the top ports 8 of tap water ozzle lower body 1 on pad 4 covers one pad 10 at top, screw mandrel in the tap water ozzle upper body 2 pierces into the center of leather packing piston valve 3, and the top ports 8 of tap water ozzle lower body 1 is spirally connected with the bowl bodies 9 of tap water ozzle upper body 2.
