Description

Anti-drip faucet

technical field

The anti-drip faucet described in the utility model relates to a water-saving faucet.

Background technique

For a long time, the water supply department has been looking for good solutions to solve the problems of residents dripping water, unmeasured water meters, high leakage rate, and serious losses of enterprises.

According to the statistics of relevant departments, the leakage rate of residents' water is as high as 30% to 50%, which not only causes a serious waste of water resources, but also directly affects the economic benefits of the water supply department, causing many social contradictions. The property management regulations of the State Council clearly stipulate that: water supply enterprises should check the meter at each household, implement the system of one household, one meter, and charge according to the actual number and cannot be shared equally. Therefore, if the problem of dripping water is not resolved, the survival of water supply enterprises will be endangered.

The core part of the faucet is the two internal ceramic pieces, namely the fixed piece and the moving piece. When the moving piece rotates around the center when the valve cover is rotated, a gap will be created between the moving piece and the fixed piece to achieve the purpose of water flow. , but when the rotation angle of the bonnet is very small, the gap formed between the moving pieces and the predetermined pieces is a small triangle. To a certain extent, the water passing through this gap is drop by drop, so that the slow dripping will not cause the rotation of the water meter. , thus achieving the purpose of stealing water resources.

In order to prevent dripping water, the reform of water meters and faucets at home and abroad has the following methods:

(1), the anti-drip faucet of the existing patent declaration, the anti-drip of the faucet depends on spring tension and water pressure.

(2), IC card, TM card (smart card type) water meter and code type water meter will become mainstream products. This type of water meter is suitable for the management system under the condition of "pay now and use later".

(3) Transform the mechanical gears inside the water meter, etc.

The problems of the above-mentioned water meters and faucets include:

(1) The principle of the water meter is to rely on water to drive the reading of the mechanical gear, its accuracy is poor, and the water meter will not go when the short and thin water flow and drip. Practice has proved that the accuracy of the mechanical water meter cannot be changed.

(2) Recently, someone invented an electromagnetic digital display water meter (a national patent has been applied for), and replaced the mechanical water meter. Its accuracy has also reached the standard, but it cannot cope with the problem of power failure.

(3), water meters such as IC card, TM card (smart card type) all need electricity, can't solve the problem of power outage equally, and existing people make a fuss on the card, steal, water leakage phenomenon is more serious.

(4) The problem existing in the anti-drip faucet of existing patent application is: the technology of original production faucet will be changed, and the tensile strength of the spring is inversely proportional to the time, and the service life is short.

For the problems existing in the above-mentioned prior art, it is very necessary to study and design a novel anti-drip water tap, thereby overcoming the problems existing in the prior art.

Contents of the invention

In view of the above-mentioned problems in the prior art, the purpose of this utility model is to study and design a new type of anti-drip faucet, so as to solve the fine-tuning valve cover caused by the original structure, which is caused by the tiny triangular gap formed between the moving piece and the fixed piece. The water dripping problem caused by it, and the use of smart cards, electromagnetic water meters, and changing the internal process of faucets to prevent water leakage and other problems are high cost and low efficiency problems.

The anti-drip water faucet described in the utility model is composed of a valve body, a moving piece and a fixed piece; the fixed piece is fixed in the groove on the inner sleeve by two protrusions; The upper part; the two inserts at the lower part of the knob are inserted into the slots of the moving piece; the valve cover is installed on the knob, when the valve cover is rotated, the inserts on the knob drive the center of the moving piece to rotate as an axis, which can make the gap between the moving piece and the fixed piece form a gap.

The moving piece and the fixed piece are made of ceramic material.

The utility model changes the structure of the moving piece so that when the valve cover is rotated, the plug-in on the knob drives the moving piece to rotate around the center, and a gap is formed between the moving piece and the fixed piece, which is not the original triangular shape. , but a hole composed of two parallel straight lines and parallel curves, which increases the flow of water and prevents the formation of tiny water droplets, thereby solving the problem of dripping water resources.

The utility model has the following advantages:

1. The utility model changes the geometric shape of the water outlet hole, so that when the valve cover is slightly rotated, there will be no very small water droplets seeping out, and the effect of water saving is achieved.

2. The utility model only changes the shape of the movable piece, and its diameter and thickness are unchanged, which is convenient for installation and use.

3. The utility model only replaces one part of the moving plate in the original water tap, and the cost is low, and it is convenient for popularization and use.

Description of drawings

The utility model has 4 accompanying drawings, wherein:

Accompanying drawing 1 is the structural representation of the utility model;

Accompanying drawing 2 is the structural representation of moving piece;

Accompanying drawing 3 is the structural representation of fixed piece;

Accompanying drawing 4 is A-A sectional view of Fig. 1.

In the figure: 1, bonnet 2, moving piece 3, fixed piece 4, inner sleeve 5, valve body 6, knob 7, gap 8, slot 9, protrusion 10, insert 11, groove.

Detailed ways

The specific embodiment of the utility model is shown in the accompanying drawings, and the accompanying drawing 1 is composed of a valve body 5, a moving piece 2, and a fixed piece 3; the fixed piece 3 is fixed on the inner sleeve 4 by two protrusions 9 The moving piece 2 is installed on the upper part of the fixed piece 3; the two inserts 10 at the bottom of the knob 6 are inserted into the slot 8 of the moving piece 2; the valve cover 1 is installed on the knob 6, when the valve cover 1 is rotated At this time, the insert 10 on the knob 6 drives the center of the moving piece 2 to rotate as an axis, so that a gap 7 is formed between the moving piece 2 and the fixed piece 3 .
