Problems solved by technology

Most of the existing technology is a pressure rod structure. During normal operation, the pressure rod will move up and down with the change of temperature. The average number of movements per season is about 3000 times. The valve core will wear the sealing ring due to the long-term movement of the pressure rod, resulting in poor sealing. The phenomenon of water leakage has caused the thermostatic valve to be maintained or replaced every year, which brings inconvenience to the user, and serious water leakage will also cause damage to the user's indoor items

Abstract

The invention relates to a leak-proof constant temperature valve with an adjustable KV (kilovolt) value, belonging to the field of water heating valves. The leak-proof constant temperature valve is characterized in that a sealing ring is sleeved into a ring groove corresponding to a rotating shaft; the rotating shaft is inserted into a hole of a rotating shaft sleeve; a clamping spring is used for enabling the rotating shaft to be fixed with the rotating shaft sleeve; a lifting barrel is screwed into an inner hole of the rotating shaft sleeve by threads; a return spring cover penetrates through a connecting rod and the sealing ring from top to bottom, and is screwed with the return spring into a whole by threads; and a rubber expansion ring is sleeved into a rubber expansion ring seat andthen is arranged in an inner cavity of a leak-proof sleeve. The leak-proof constant temperature valve is convenient to adjust the KV value according to the need of heat balance, and can not generate leakage for long-term working.

Description

technical field [0001] A leak-proof thermostatic valve with adjustable KV value is used for constant temperature control of indoor temperature and belongs to the field of water heating valve manufacturing. Background technique [0002] Traditional winter heating, heating, the flow control of hot water flowing through the pipeline radiator is regulated by gate valves, stop valves, etc. installed at the radiator inlet; users need to manually adjust the medium flow according to room temperature changes, which is very difficult to use. inconvenient. For convenience, many users adjust the flow rate of the valve to the maximum. When the indoor temperature is too high, they open the window to ventilate and cool down, resulting in a great waste of energy; because the valve cannot adjust the KV value, the indoor temperature of some users is too high. The user's room temperature is too low. With the increasingly severe situation of building energy conservation and the gradually cle...
