One-way safety valve provided with decompression component and water heater applying same

Abstract

The invention discloses a one-way safety valve provided with a decompression component and a water heater applying the same. The one-way safety valve comprises a main valve body module with the internal leakage function and a branched valve body module with the external leakage function; the branched valve body module is detachably connected with the upper side wall of the main valve body module;and the main valve body module comprises the decompression component for decompression. According to the one-way safety valve provided with the decompression component, the safety valve and the decompression component are integrated, so that safe pressure limiting and decompression can be simultaneously obtained through mounting the one-way safety valve provided with the decompression component onthe water heater at one time, the assembling step is reduced, the production efficiency is improved, the production cost is reduced and the user experience degree is increased.

Description

technical field [0001] The invention belongs to the technical field of water inlet safety valves, in particular to a one-way safety valve with a decompression assembly and a water heater using the same. Background technique [0002] At present, in order to prevent the internal pressure of the water heater from exceeding the limit value, it is generally necessary to install a safety valve at the water inlet port of the water heater, so that when the water heater is overpressured, part of the water will be discharged through the valve port opened by the safety valve to relieve the pressure of the water heater. When the existing high-rise floors are used for secondary water supply, the pressure often exceeds the rated pressure of the water heater, and the inside of the water heater will leak water through the one-way safety valve to release the pressure and drain water, which will cause users to mistakenly believe that the water heater is leaking and cause complaints. Therefore,...

AI Technical Summary

Problems solved by technology

When the existing high-rise floors are used for secondary water supply, the pressure often exceeds the rated pressure of the water heater, and the inside of the water heater will leak water through the one-way safety valve to release the pressure and drain water, which will cause users to mistakenly believe that the water heater is leaking and cause complaints. Therefore, in order To reduce the water inlet pressure of the water heater, a pressure reducing valve needs to be installed at the water inlet port of the water heater

[0003] However, when assembling the existing water heaters, it is necessary to install a safety valve and a pressure reducing valve to the water inlet port respectively, so as to realize the pressure relief and decompression functions at the same time, which will inevitably cause cumbersome assembly steps of the water heater, affecting production efficiency and cost
