Automatic pressing equipment simulating water hammer for water meter and use method thereof

Abstract

The invention provides automatic pressing equipment simulating a water hammer for a water meter. The equipment comprises a controller, a motor, a piston cylinder, a pressure sensor, the water meter, afirst solenoid valve, a second solenoid valve and a water tank; the motor is arranged at the top end of the piston cylinder, an output end of the motor is connected to a piston in the piston cylinderthrough a rolling ball screw, the motor drives the piston in the piston cylinder to move, the bottom end of the piston cylinder is communicated with a three-way valve, the water tank is communicatedwith the three-way valve through a water inlet pipe, one end of the water meter is communicated with the three-way valve through a water outlet pipe, and the second solenoid valve is arranged at the other end of the water meter; the two ends of the piston cylinder are both provided with in-place detection switches; the first solenoid valve is arranged on the water inlet pipe, and the pressure sensor is arranged on the water inlet pipe and between the first solenoid valve and the three-way valve. The automatic pressing equipment simulating the water hammer for the water meter has the advantagesthat the structure is simple, the operation is convenient, quick switch of high and low pressure and precise simulation of the water hammer can be achieved rapidly, not only can the quality of the water meter be detected rapidly, but also the manpower can be reduced.

Description

technical field [0001] The invention relates to a water hammer suppressing device, in particular to a simulated water hammer automatic suppressing device for a water meter. Background technique [0002] The traditional experimental water meter simulation water hammer suppression equipment uses a press to hit a certain pressure value and maintain it, and then manually releases the pressure to check the quality of the water meter, which wastes manpower and cannot realize fast switching between high and low pressure to accurately simulate water hammer . In the actual installation of water meters, the changing pressure and large water hammer will have a certain impact on the water meters, so the quality of the water meters is very important. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simulated water hammer automatic pressing device for water meters and its use method. It has a simple structure and is easy to ...
