Adjustable valve for preventing autorotation of water meter

Abstract

The invention discloses an adjustable valve for preventing autorotation of a water meter. A rubber membrane is arranged between an upper valve body and a lower valve body; an adjustable rotor is arranged in a cavity of the upper valve body; and the lower end of the rotor is provided with a spring. The adjustable valve for preventing the autorotation of the water meter performs stepless adjustment on the efficiency for preventing water fluctuation according to the actual situations of different water supply pressure areas and different meter positions; under the condition that the water supply pressure of a user is ensured, the autorotation phenomenon of the water meter is effectively avoided when the user does not use the water; and the adjustable valve for preventing the autorotation of the water meter integrates three functions of an anti-autorotation valve, a stop valve and a check valve, and has the advantages of low cost, long service life, low pressure loss, relatively simple manufacturing process, high economical efficiency and wide market prospect.

Description

technical field [0001] The invention relates to a valve, in particular to an adjustable waterproof meter self-rotating valve. Background technique [0002] In recent years, with the continuous advancement of the "one household, one meter" work, many old contradictions between water supply companies and users have been reduced, such as the inconsistency between the total meter and the sub-meter stop code, excessive pressure in the water supply network and insufficient water pressure in households. However, many new water supply problems have arisen: such as the selection of the installation location of household meters, the protection of measuring instruments in winter, the copying of water meter stop codes, and the phenomenon of water meters not using water to rotate, etc. Among these problems, the problem of the water meter not using water to rotate itself is particularly prominent, which leads to a high number of user complaints and even unnecessary legal disputes.

Problems solved by technology

[0002] In recent years, with the continuous deepening of the "one household, one meter" work, many old contradictions between water supply companies and users have been reduced, such as the inconsistency between the total meter and the sub-meter stop code, excessive pressure in the water supply network and insufficient water pressure in households. However, many new water supply problems have arisen: such as the choice of the installation location of household meters, the protection of measuring instruments in winter, the copying of water meter stop codes, and the phenomenon of water meters not using water, etc.

The copper joint anti-jamming valve widely used at present has a certain effect on the rotation of its waterproof meter under specific water supply conditions, but under different water supply pressure conditions, it is impossible to adjust the anti-rotation performance of the product according to the actual situation of different epitopes. size adjustment

Therefore, in many residential quarters where the phenomenon of water meter rotation is serious, the installation and use of this copper joint anti-interference valve still cannot completely solve the problem of water meter rotation without water.

[0008] 2. High pressure loss

The pressure loss value of the copper joint anti-jamming valve product is high during use, reaching 0.06MPa, and the water pressure is significantly reduced when used by high-rise users, resulting in the failure of the gas water heater to ignite normally

Therefore, the scope of application of this product is limited, and it is not suitable for large-scale promotion.
