Description
Technical field
The utility model belongs to valve technology field, particularly relates to a kind of guidance type single seat thermostat valve.
Background technique
Self-supporting temperature-sensing valve utilizes heated liquid to expand and the incompressible principle of liquid realizes automatically regulating.Expansion of liquids in temperature transducer is uniform, and its control action is proportion adjustment.During controlled medium temperature change, the temperature sensing liquid volume in sensor is along with expansion or shrink.When controlled medium temperature is higher than setting value, temperature sensing liquid expands, and promotes the downward throttle down of spool, reduces the flow of heating agent; When the temperature of controlled medium is lower than setting value, temperature sensing liquid shrinks, and Returnning spring promotes spool and opens, and increases the flow of heating agent.
The temperature of user indoor controls to be realized by radiator thermostatic control valve.Radiator thermostatic control valve is made up of radiator valve, flow control valve and a pair link, and wherein the core component of radiator valve is sensor unit, i.e. thermometer bulb.Thermometer bulb can be responded to the change of ambient temperature and produce Volume Changes, drives regulation valve core to produce displacement, and then regulates the water yield of radiator to change the heat dissipating capacity of radiator.Thermostatic valve setting temperature can artificially regulate, and thermostatic valve can automatically control by setting requirement and regulate the water yield of radiator, thus reaches the object controlling room temperature.Thermostat valve is generally before being contained in radiator, by flow automatic regulation, realizes the room temperature that resident needs.Thermostat valve have two-way thermostat valve and three-way temperature control valve point.Three-way temperature control valve is mainly used in the single-main distribution with crossing pipe, and its diverting coefficient can change in the scope of 0-100%, and Flow-rate adjustment leeway is large, but price comparison is expensive, and structure is more complicated.Two-way thermostat valve have for two-pipe system, have for single-main distribution.Two-way thermostat valve resistance for two-pipe system is larger; Resistance for single-main distribution is less.The temperature-sensitive bag of thermostat valve and valve body are generally assembled into an entirety, and namely temperature-sensitive bag itself is on-the-spot indoor temperature transmitter.If needed, remote temperature sensor can be adopted; Remote temperature sensor is placed in the room requiring temperature control, and valve body is placed in a certain position on heating system.
The thermostat valve of current practical application, adjusting handle is connected mainly through regulating block with valve stem casing, for face contacts between regulating block with valve stem casing, is easy to the phenomenon occurring skidding, thus causes malfunction.
