Abstract

The utility model relates to the improved type of a spiral lifting type water tap, and belongs to the categories of the architectural hardware, the pipeline fittings and the chemical pipelines. A helical groove and a fixing screw pin cause a valve core to lift. A water storage tank is arranged between a water inlet hole and a water outlet hole. The upper and the lower ends of the valve core are all provided with an end face sealing ring. Thus, the utility model generates no leakage when the water tap is in the closing and the opening processes and is fully opened.

Description

Leakproof water tap

The utility model belongs to architectural hardware, pipeline fittings category.Be applicable to be installed on tap water or sanitary equipment and the chemical industry pipeline, be specially adapted to the connection of full automatic washing machine inflow pipe.Conveniently, reliably, cost is low.

The complex structure of existing water tap has 3 thread die cutting mechanisms, processing difficulties, and the cost height, the sealing material on spool top adopts asbestos rope etc. mostly, and it is unreliable to seal, and easily leaks.In addition, during asbestos fiber was soluble in water, the long-term drinking influence was healthy.

CN88217375.8 provides a kind of improvement design, as shown in Figure 1.Simple in structure, do not adopt asbestos rope to seal, relatively safety.But there is following several shortcoming in this mechanism:

1. can only be used in water nozzle occasion vertically downward.

2. after having, water nozzle connects that (such as inlet valve of automatic washing machine) can not use under the occasion of valve.

3. screw 2 long period of soaking particularly having under the situation of Korrosionsmedium, are corroded in working medium easily.

The utility model has overcome above-mentioned shortcoming fully, and a kind of simple in structure, novel water nozzle that can connect valve and use in tap water or Korrosionsmedium, easy processing, low cost later on, not leak is provided.

As shown in Figure 2.One spiral chute is arranged on the valve rod 5, and screw 6 is embedded in the spiral chute of valve rod 5 the end unthreaded portion by valve gap 7.Rotary valve rod 5 can make spool 3 do elevating movement.Spool 3 can adopt modes such as screw thread or close-fitting and valve rod 5 to fuse.

Only need revolve in the opening process of water nozzle that turn around can be from being closed to full open.Because water inlet area S _BWith osculum area S _CAnd aqua storage tank sectional area S _DRatio be S _C＞S _B, S _D＞＞S _BSo flow of inlet water can not arrive A ' all the time from minimum to maximum, and flows away from C.

When water nozzle was closed, spool was at bottom position.Lower seal 2 is pressed on the B ' of aqua storage tank lower end surface, and the water inlet is sealed.When after having, connecing valve (as the various internally piloted valves in full automatic washing machine inflow valve or the Chemical Manufacture), valve rod can be threaded to the aqua storage tank the topmost part, seal ring 4 be pressed on the A ' of aqua storage tank upper-end surface make its sealing, will not leak.

Because the position of screw 6 does not whatsoever contact with working medium under the situation on the top of water nozzle, thus not perishable, use or do not use for a long time the dead situation of can not becoming rusty for a long time.Under the situation that water nozzle is inverted or level is used, can add seal ring at the spiral chute lower position of valve rod 5.

The parallel slot (about 45 °～90 °) that respectively is provided with one section no lead angle in ending place of spiral fluted upper and lower end is for keeping section, both can keep upper-lower seal effectively, can prevent someone's excessive damage seal ring of exerting oneself again effectively, prolong the working life of seal ring greatly.

Fig. 2 is the embodiment of a cold water tap

The utility model also is applicable to takes over water nozzle, long neck water nozzle, urinal water nozzle, chemical examination water nozzle, wash basin and Water tap for bathtub etc.Can also directly apply to various chemical industry pipelines and need corrosion resistant occasion.The Manufacturing material of water nozzle main body can be coloured or ferrous castings, also can be various resistant materials such as nylon, ABS, fluoroplastic.Processing and fabricating is easy, and cost is low, and working service is convenient, and the life-span is long, can stop long-standing run, drip, leak phenomenon effectively.
