Embodiment Construction

[0013] In order to overcome the problem of pipeline vibration or disturbance caused by opening the faucet under high water pressure, this embodiment provides a figure 1 The piston-type anti-disturbance water meter shown includes a pipe section 1 and a water meter 2 installed between the water inlet 3 and the water outlet 4 of the pipe section 1. Compared with the existing water meter, its improvement is: set in the pipe section 1 There is a cylindrical section 5 extending axially along the pipe section 1, the outer diameter of the cylindrical section 5 is larger than the inner diameter of the inner end of the water inlet 3, and the inner diameter of the cylindrical section 5 facing away from the water flow is larger than the inner diameter of the water outlet. The coil spring 6 of the inner diameter of the inner end of 4 is fixedly connected with the inner end of the water outlet 4 .

[0014] In this way, when the water tap under high pressure is suddenly opened to cause water...

Abstract

The invention provides a piston type anti-disturbance water meter which comprises a pipe segment (1) and a water yield meter (2) mounted between a water inlet (3) and a water outlet (4) of the pipe segment (1).A cylindrical segment (5) extending in the axial direction of the pipe segment (1) is arranged in the pipe segment (1).The outer diameter of the cylindrical segment (5) is larger than the inner diameter of the inner end of the water inlet (3).The end, opposite to the water flow direction, of the cylindrical segment (5) is fixedly connected with the inner end of the water outlet (4) through a spiral spring (6), and the inner diameter of the spiral spring (6) is larger than the inner diameter of the inner end of the water outlet (4).The cylindrical segment and the spiral spring are arranged between the water inlet and the water outlet in the pipe segment of the water meter, and therefore vibration, namely, disturbance, caused by a sharp drop of water pressure can be effectively buffered, a good promoting function is achieved on safe use and the service life of the water meter, and especially a user cannot be scared; the structure is simple, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of hydropower, in particular to a detection instrument for measuring water consumption, that is, a piston type anti-disturbance water meter. Background technique [0002] The water meter is generally installed on the water inlet pipe section of the user's water room, instead of being installed outdoors where the staff can check it like the electric meter. Therefore, it has a certain degree of concealment, which provides convenience for users who steal water. [0003] In order to prevent users from stealing water, the invention patent application with the patent application number 200410086486.1 discloses a kind of anti-theft water meter. figure 1 The water inlet of the shown water meter (two mesh pieces 4 are installed at the water inlet) is installed with a check valve 5, that is, a one-way valve, to block the water flow when the user reversely installs the water meter, so as to prevent the user from revers...
