Description
Technical field
This utility model relates to a kind of heating system temperature-sensing valve, the temperature regulation in heating system.
Background technology
Temperature control valve (TCV) is called for short temperature-sensing valve, and in China's new building house, temperature-sensing valve is commonly used, is typically mounted on
Before the heating radiator of residence and public building, pass through flow automatic regulation, it is achieved the room temperature that resident needs.Temperature-sensing valve can basis
The different requirement of user sets room temperature, and its sensor is constantly experienced room temperature and is automatically adjusted heat at any time according to current heat demand
The supply of amount, to prevent room temperature overheated, reaches the comfort level that user is the highest.
Temperature-sensing valve utilizes heated liquid to expand and the incompressible principle of liquid realizes being automatically adjusted.In temperature sensor
Expansion of liquids is uniform, and its control action is proportion adjustment.During the change of controlled medium temperature, the temperature sensing liquid body in sensor
Long-pending along with expansion or shrinkage.When controlled medium temperature is higher than setting value, temperature sensing liquid expands, and promotes spool to close downwards valve,
Reduce the flow of heating agent；When the temperature of controlled medium is less than setting value, temperature sensing liquid shrinks, and back-moving spring promotes spool to open,
Increase the flow of heating agent.This temperature-sensing valve is due to open and close switching frequently, and service life is short, needs often to carry out keeping in repair more
Change.
Utility model content
The purpose of this utility model is to provide the heating system temperature-sensing valve of a kind of simple in construction, it is to avoid opening and closing switching frequency
Numerous, reduce opening times, increase the service life, ensure indoor temperature simultaneously.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of heating system temperature-sensing valve, including valve body, protective cover and sensor, described valve body is a transverse tube and a longitudinal tubule (L tubule)
The inversion T-shaped structure that the connection that intersects vertically is formed, is sequentially connected with from top to bottom in longitudinal tubule (L tubule) and arranges performance element, pressing plate, spring, work
Stopper rod and spool, the bottom surface of spool arranges sealing ring, and the position that transverse tube and longitudinal tubule (L tubule) are interconnected arranges one by transverse tube inner chamber one point
Being the isolation baffle plate of two, described isolation baffle plate includes the transverse slat of a vertical longitudinal tubule (L tubule) axis setting and is arranged on two pieces of transverse slat two ends
Swash plate, one end of swash plate is connected with transverse slat；The other end of swash plate is connected to transverse tube inwall, transverse slat offers and sealing ring gap
The through hole coordinated, described protective cover is located at the top of the longitudinal tubule (L tubule) of valve body, and described sensor is by installing overprotection cover roof
Conduit is connected with performance element.
Being improved by of above-mentioned heating system temperature-sensing valve, the external diameter of described sealing ring is less than the aperture of the through hole on transverse slat
2-7mm。
Further improvement is that of above-mentioned heating system temperature-sensing valve, the external diameter of described sealing ring is than the through hole on transverse slat
The little 5mm in aperture.
The beneficial effects of the utility model are:
Heating system temperature-sensing valve described in the utility model, when controlled medium temperature is less than in setting value, temperature sensing liquid
Body shrinks, and spool is opened, and increases the flow of heating agent；When controlled medium temperature is higher than setting value, temperature sensing liquid expands, piston rod
Promotion spool is downward, because the external diameter of sealing ring reduces, so presenting is semi-closed state, flow rate of heat medium is the least, in a timing
In be temperature keep constant.It thus is avoided that opening and closing switching frequently, increases the service life, ensure that indoor temperature is not less than ice simultaneously
Point.
