Water meter shell pressure detection device and detection method

Abstract

The invention discloses a water meter shell pressure detection device and method, and relates to the field of water meter production equipment. The water meter shell pressure detection device comprises a base, and a water meter clamping structure used for fixing a water meter is arranged at the middle end of the top of the base; the water meter clamping structure comprises first convex blocks, a rotating rod, threaded grooves, a sliding plate, a first rotating disc, a rocker, a water inflow hose, a rubber conical pipe, a transverse pipe, a water outflow hose and a conical pipe; the first convex blocks are symmetrically and fixedly installed on the top of the base; the first convex blocks are rotationally connected with the rotating rod through fixedly installed bearings; the first rotating disc is fixedly connected to the right end of the rotating rod; the rocker used for pushing the first rotating disc to rotate is fixedly connected to the outer edge of the side wall of the first rotating disc; and threaded grooves are symmetrically formed in the positions, between the first convex blocks, of the rotating rod. With the water meter shell pressure detection device and detection method of the invention adopted, the water meter can be fixedly installed between the transverse pipes conveniently.

Description

technical field [0001] The invention relates to the field of water meter production equipment, in particular to a water meter casing pressure detection device and a detection method. Background technique [0002] A water meter is an instrument for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. They originated in the United Kingdom. The development of water meters has a history of nearly two hundred years. , you should first estimate the size and flow range of the flow normally used, and then choose the water meter of the specification with the usual flow closest to the value as the first choice. [0003] The internal structure of the traditional water meter can be divided into three parts: the shell, the sleeve, and the inner core from the outside to the inside. The water meter shell is a component that is in direct contact with water. It cannot be put into u...

[0003] The internal structure of the traditional water meter can be divided into three parts: the shell, the sleeve, and the inner core from the outside to the inside. The water meter shell is a component that is in direct contact with water. It cannot be put into use. Now some detection devices are designed for pressure detection, but the monitoring device can only adapt to a single type of water meter for detection, and cannot adapt to water meters of different specifications for detection. At the same time, the existing devices move vertically for single Point detection, it is inconvenient to adjust to different positions for multi-point detection, and the detection results are prone to incompleteness
