Constant-temperature circulating valve and mounting and using method thereof

Abstract

The invention discloses a constant-temperature circulating valve. The constant-temperature circulating valve comprises a valve body, an adjusting temperature bulb and a sterilizing temperature bulb are arranged in the valve body, the lower end of the adjusting temperature bulb and the lower end of the sterilizing temperature bulb are each sleeved with a working spring, the middle of the adjustingtemperature bulb and the middle of the sterilizing temperature bulb are sleeved with a control piston and a bypass piston respectively, and the upper end of the adjusting temperature bulb and the upper end of the sterilizing temperature bulb are each fixedly connected with a spring seat. According to the constant-temperature circulating valve and the mounting and using method thereof, in a domestic hot water system, in order to ensure that each hot water circulating branch of a water supply system reaches the required temperature, ensure that hot water can be used immediately after being opened and effectively prevent legionella breeding, the flow of a circulating loop is adjusted so that the phenomenon of different loop water temperatures can be avoided, the design of different-stroke loops with automatic balance of the hot water system is realized, the pipeline investment is reduced, more comfortable experience is realized, the thermal sterilization requirement can be met, and a settemperature can be automatically maintained when the constant-temperature circulating valve is installed in each loop of the hot water circulation system.

Description

technical field [0001] The invention relates to the technical field of a constant temperature circulation valve system, in particular to a constant temperature circulation valve and an installation and use method thereof. Background technique [0002] Studies have shown that under the condition of water temperature ≤ 45°C, the bacterial reproduction rate is accelerated and the risk of microbial contamination increases. Among them, Legionella pneumophila has the characteristics of multiplying in the water supply system and has a high pathogenicity rate. The World Health Organization and other countries have listed it as the number one threat. Especially in the hot water circulation system, people must pay great attention to it. Low water temperature, low flow rate, biofilm, stagnant water areas, etc. are all favorable conditions for the growth of Legionella. [0003] Traditional hot water systems often have problems such as uneven cooling and heating at each water supply end...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of uneven cooling and heating at each outlet and high energy consumption in the traditional hot water system, which brings great troubles to the user's comfort, safety and operation and maintenance costs. Moreover, it cannot ensure that each hot water circulation branch of the water supply system can reach the required temperature, and it cannot effectively prevent the growth of Legionella, and the problem of uneven water temperature in the circuit occurs. A constant temperature circulation valve and its installation and use method are proposed
