Abstract

The utility model relates to a water-saving nozzle, which belongs to the valve component technical field. An existing water tap needs regulating for a plurality of times when controlling the water volume, which is inconvenient and wastes water. The utility model aims at providing the water-saving nozzle which can limit the water volume and is composed of a valve pocket and a valve core, wherein a water hole and a side hole are arranged on the valve core, the bottom is sealed, an outer screw thread is arranged under a limit bench of the valve core, an inner screw thread of the valve pocket is screwed on the outer screw thread of the valve core, a water outlet hole is arranged under the valve pocket, the bottom of the valve core is covered on the water outlet hole of the valve pocket, and a packing ring is sleeved on the lower middle portion of the valve core. When in use, the valve pocket is rotated, water flows out from the water outlet hole through the water hole of the valve core and the side hole of the valve core, and the water volume of the water outlet hole can be controlled through regulating the height of the valve pocket upwards and downwards. The purpose of saving water can be reached through using the water-saving nozzle.

Description

Water-saving spray head

Technical field

The utility model belongs to the valve member technical field, particularly a kind ofly is installed in water-saving spray head on the tap, can the manual adjustments water flow.

Background technology

Existing tap is when adjusting mouth of a river water flow, need rotation or up and down the master cock handle regulate and control, sometimes need to carry out two to three actions or fine setting more frequently, just can reach the water yield that oneself needs, when duty finishes, when washing hand or washing dish, just need turn off the tap, so when carrying out same work next time and needing onesize water yield, again water tap is adjusted once more, obviously like this, increased the amount of labour, and a large amount of water-whites runs off in vain in adjustment process.

In some occasion, for example (,) place such as hotel, dining room, public lavatory, tap one is opened, and water yield is very big, has substantially exceeded water consumption required when people wash one's hands, and the water of ejection can cause waste too much.

The utility model content

The purpose of this utility model provides a kind of water-saving spray head that limits water yield, solve existing tap regulate discharge loaded down with trivial details, cause the problem of water resource waste easily, its embodiment is as follows:

Water-saving spray head is made up of valve pocket and spool, and there is the limbers at the spool middle part, on the excircle on spool top limiting stand is arranged, and there is external screw thread the limiting stand below; Spool is installed in the valve pocket, and spool has side opening on the side, bottom lock; The valve pocket upper end open, the valve pocket opening part has internal thread, and the valve pocket internal thread screws on the spool external screw thread, and there is apopore the valve pocket lower end; The bottom of spool is relative with the apopore of valve pocket bottom, and covers on the top of valve pocket bottom apopore; In the spool middle and lower part, be with a sealing ring, sealing ring is close between the inside and outside wall between spool and the valve pocket.

During use, with valve core housing on the water nozzle of tap, rotate up valve pocket, when valve pocket was conflicted limiting stand, spool bottom just withstood on the apopore on the valve pocket, and apopore is shut fully, at this moment the water that flow into the spool from tap just can not spray from apopore, because between spool and the valve pocket sealing ring is arranged, the water in the spool also can not ooze out the gap that is threaded between spool and valve pocket, thrift lock is in closed condition.

When needs are adjusted to certain state with the water yield, can be rotated down valve pocket, valve pocket moves down, produce the gap between the apopore of spool bottom and valve pocket bottom, when fetching boiling water tap, water is through the spool limbers, the spool side opening, flow out from the apopore of valve pocket bottom, control valve cover height up and down is the gap between controllable valve core bottom and the valve pocket apopore, thereby the size of control apopore water yield, can maintaining valve be enclosed within invariant position in the spool in case adjusting finishes, when repeat same washing work next time, the tap of only need fetching boiling water, then required water for amount will be from the apopore of thrift lock jet flow and going out, saved greatly and adjusted the time and the amount of labour that the water yield spent, very easy to use.

In use, owing between spool and the valve pocket sealing ring is arranged, the water in the spool also can not ooze out the gap that is threaded between spool and valve pocket.

For fixed seal ring better, make its sealing effectiveness better, design below can increasing in said structure: there is the sealing ring limiting stand external screw thread lower end of spool, and there is seal groove the internal thread lower end of valve pocket, and sealing ring is positioned at seal groove.Sealing ring is stuck in the seal groove in the moving process of valve pocket all the time like this, and current can upwards not backflowed along the gap between spool and the valve pocket.

For the limbers flowing water that makes valve core cavity is unobstructed, the spool limbers is designed to one and goes up bottom width, the narrow round table-like cavity of going to the bottom, and its bottom seal, and side opening is two through holes that also radially run through the spool sidewall near the valve core cavities bottom; The apopore quantity of valve pocket bottom is no less than two, and the water hole is circumference and arranges; With covering on the outer, bottom of the spool of apopore top, be set to an annular boss, make it seal delivery port better, avoid causing sealing condition not good situation in the mouth of a river to occur because of spool bottom when scraggly.

At middle part, spool limbers a screen pack can be installed, with the impurity that flows out in the filtered water tap.

The specific embodiment

Embodiment one: as Fig. 1, Fig. 2 and water-saving spray head shown in Figure 3, form by valve pocket 1 and spool 5, there is limbers 8 at spool 5 middle parts, limbers 8 is one and goes up bottom width, the narrow round table-like cavity of going to the bottom that its middle part is equipped with screen pack 7, on the excircle on spool 5 tops limiting stand 9 is arranged, there is external screw thread 3 limiting stand 9 belows, its bottom 12 is sealed, in close spool 5 intracavity bottoms 12 lateral location, radially at two through holes 11 that run through the spool sidewall; Spool 5 is installed in the valve pocket 1, valve pocket 1 upper end open, and opening part has internal thread 4, and valve pocket internal thread 4 screws on the spool external screw thread 3, and there is apopore 14 valve pocket 1 lower end, and apopore 14 has five, and apopore 14 is circumference and arranges; The bottom 12 of spool 5 is relative with the apopore 14 of
