Description
Technical field
The utility model relates to a kind of safety valve, and is especially relevant with heat-operated valve.
Background technique
Existing heat-operated valve only is applied to field of water heaters usually, in other watering equipment, seldom use, and some water devices are arranged, when breaking down, also can produce the situation of the hurried rising of water temperature as water pump, hydraulic giant etc., but often cause the generation of accident owing to safe pressure relief devices such as not having heat-operated valve, the this moment of pressure release in time just can be avoided the generation of accident.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, and is easy for installation, can avoid because of the hurried rising of water temperature has an accident, applicable to the heat-operated valve of various water devices.
For achieving the above object, the utility model is achieved through the following technical solutions.Heat-operated valve, comprise valve body, temperature control element, spring, spring-positioning device and sealing gasket, temperature control element, spring, spring-positioning device and sealing gasket are located in the inner chamber of valve body, be provided with protruding circle in inner chamber, sealing gasket is located at temperature control element top, and is positioned at protruding circle below, be provided with the relief hole that is in communication with the outside on valve body top, spring is located between spring-positioning device and the temperature control element, and valve body lower portion is provided with connecting thread, is provided with flow channel between temperature control element and the interior cavity wall.
The utility model compared with prior art has the following advantages: (one) can be widely used in the various water devices, stops effectively to have an accident because of the hurried rising of water temperature; (2) be that connecting thread by valve body lower portion is connected with various water devices, and be set to polygonal in valve body middle part profile, easier for installation; (3) be the folding of controlling sealing gasket and protruding circle by moving up and down of push rod, thus the control pressure release, and compact structure is reasonable.
