Safety valve for energy-saving and environment-friendly water heater

Abstract

The safety valve comprises a valve body, the middle of the inner wall of the valve body is fixedly connected with a sealing limiting ring, the bottom of the inner wall of the valve body is sleeved with an air guide mechanism, the middle of the inner wall of the valve body is fixedly connected with a pressure relief mechanism, and the top end of the valve body is fixedly connected with a guide mechanism. The working lengths of a limiting spring and a preloading spring are changed through a limiting bolt and a limiting baffle ring, the working position adjustment of a mounting base on the inner side of the device is completed, the distance between a pressure relief hole in a pressure relief base and an upper air guide hole in an air guide base is changed, the working volume adjustment of a variable pressure stabilizing cavity is completed, and the situation that when the water pressure on the inner side of the device changes, the working volume is adjusted is avoided. The water pressure in the water heater changes frequently due to overheated steam leakage, the problem that energy consumption is increased due to pressure unbalance of the water heater is solved, the working safety of the device is improved, and the problems that existing equipment is insufficient in water pressure control, low in pressure relief efficiency and inconvenient to use are solved.

Description

technical field [0001] The invention mainly relates to the field of water heaters, in particular to an energy-saving and environment-friendly safety valve for water heaters. Background technique [0002] The energy-saving and environment-friendly water heater has the function of waste heat recovery and utilization in the running state, and its heating efficiency is better than that of the traditional water heater, and the existing energy-saving and environment-friendly water heater has a higher water pressure in the working state. The requirements for the safety valve equipped with it are relatively high. [0003] The existing patent (notification number: CN107654705A) discloses a safety valve for a water heater, including a valve body on which a water outlet and an inlet are formed, and the inside of the valve body is formed with the water outlet and the inlet. The cavities communicating with each other are provided with an adjustment structure at the port of the cavity, a...
