Anti-freezing damage structure for water pressure transmitter

Abstract

The invention discloses an anti-freezing damage structure for a water pressure transmitter, which is arranged in a water pressure cavity of the water pressure transmitter and comprises an isolation buffer sheet made of silica gel and / or thermoplastic elastomer, the isolation buffer sheet faces a water inlet of the water pressure transmitter and is continuously bent to be in a concave-convex corrugated shape, and the two ends of the isolation buffer sheet are connected with the water pressure cavity. According to the anti-freezing damage structure for the water pressure transmitter, the isolation buffer sheet which faces the water inlet and is made of the silica gel and / or the thermoplastic elastomer is arranged in the water pressure cavity, and the isolation buffer sheet is bent to be in a concave-convex corrugated shape, so that when water encounters low-temperature freezing, the volume is rapidly increased, the isolation buffer plate can deform to maintain the dynamic balance of the pressure, and the influence of external unstable factors is greatly reduced, and the reliability is improved. The invention further discloses a water pressure transmitter.

Description

technical field [0001] The invention relates to the technical field of digital monitoring of water supply and drainage, in particular to an antifreeze damage structure for a water pressure transmitter and the water pressure transmitter. Background technique [0002] With the improvement of the economic level and the rapid development of the Internet of Things in recent years, environmental management and property management are also developing rapidly towards intelligence and Internet of Things. Sensor research and development and digital transmission have become an extremely important part of it. Among them, water supply and drainage The digital monitoring also has a good market prospect, and the water pressure transmitter is an indispensable basic equipment for the digital monitoring of water supply and drainage. [0003] The traditional water pressure transmitter will cause the water in the water pressure wall to freeze when the temperature is low, and the fixed ice after...

Problems solved by technology

[0005] A. Steam heat tracing; B. Insulation device box; C. Electric heating cable; however, the above three methods all have different degrees of disadvantages

[0006] At present, some water pressure transmitters are not equipped with auxiliary equipment to prevent low-temperature freezing damage. In winter, when the temperature suddenly drops below zero, the water meter installation area may also freeze; and stock property water supply, old water supply in the city, Drainage system and other auxiliary equipment for anti-freezing are not installed. In winter, the water pressure transmitter may be damaged due to freezing, or auxiliary equipment for anti-freezing is installed, or it may be due to auxiliary equipment failure or unstable power supply. Failure of thermal insulation
