Description
Technical field
The utility model relates to a kind of control valve, in particular to a kind of electric temperature control valves.
Background technique
Currently, using more universal in electric temperature control valve water-heating system.But there are media for existing electric temperature control valve
Leakage, actuator function is single, and being easy to appear failure leads to problems such as valve and relevant device damage.
Utility model content
The purpose of this utility model is to provide for a kind of electric temperature control valve, and the electric temperature control valve is easy to operate, using steady
It sets, and the flow that valve can be completed when power-off, monitoring instrument failure is adjusted, and avoids the damage of relevant device
It is bad.
In order to achieve the above object, the utility model provides following technical solution: a kind of electric temperature control valve, including valve
Body, valve seat, valve rod, spool, valve deck, gland, filler, backing plate, filler pressing sleeve, filler nail pressing and electronic temperature control actuator, it is described
Electronic temperature control actuator includes executing shell, temperature sensor, control host, power supply, motor, spring and memorial alloy, described
Temperature sensor connection control host, the control host are separately connected power supply and motor, and the motor passes through worm-drive knot
Structure connects valve rod, and the worm screw of the worm transmission structure is connected by nut with valve rod, between the nut and execution shell
Equipped with spring, the upper end of the worm screw connects memorial alloy, and the memorial alloy connects thermally conductive sheet, and the thermally conductive sheet, which is exposed to, to be held
The outside of row shell.
It is further preferred that the worm screw is equipped with adjusting nut.
It is further preferred that the top of the electronic temperature control actuator is equipped with hand-operated valve.
It is further preferred that the electronic temperature control actuator is equipped with display.
The utility model has the beneficial effects that the electric temperature control valve is easy to operate, using stablizing, and can power-off,
The flow that valve is completed when monitoring instrument failure is adjusted, and avoids the damage of relevant device.

Specific embodiment
We are described further a kind of electric temperature control valve described in the utility model in conjunction with attached drawing below.
As shown in Figures 1 and 2, a kind of electric temperature control valve of the present embodiment, including valve body 1, valve seat 2, valve rod 3, spool
4, valve deck 5, gland 6, filler 7, backing plate 8, filler pressing sleeve 9, filler nail pressing 10 and electronic temperature control actuator 11, the electronic temperature control
Actuator 11 includes executing shell 12, temperature sensor 13, control host 14, power supply 15, motor 16, spring 17 and memorial alloy
18, the connection of the temperature sensor 13 control host 14, the control host 14 is separately connected power supply 15 and motor 16, the electricity
Machine 16 connects valve rod 3 by worm transmission structure 19, and the worm screw of the worm transmission structure 19 is connected by nut 20 with valve rod 3
It connects, spring 17 is equipped between the nut 20 and execution shell 12, the upper end of the worm screw connects memorial alloy 18, the memory
Alloy 18 connects thermally conductive sheet 21, and the thermally conductive sheet 21 is exposed to the outside for executing shell 12.The worm screw is equipped with adjusting nut
22.The electronic temperature control actuator 11 is equipped with display 24.In normal operating conditions, it is monitored by temperature sensor external
Environment temperature, when environment temperature is lower than setting value, control host control motor work, the worm screw of worm transmission structure is moved up,
Spool also moves up, to increase liquid flow；When environment temperature be higher than setting value when, worm transmission structure moves down, spool also under
It moves, reduces liquid flow.Temperature change is conducted to memorial alloy by thermally conductive sheet simultaneously, is led by the variation of environment temperature
The contraction and expansion of memorial alloy are caused, thus with movable valve plug upper and lower displacement, even if automatically controlled in power-off or electronic temperature control actuator
In the case where partial fault, the also liquid throughput of adjustable valve.Relevant device is avoided to damage because of failsafe valve.
In the present embodiment, the top of the electronic temperature control actuator 11 is equipped with hand-operated valve 23.In in need or electronic temperature
When controlling actuator failures, the opening and closing that hand-operated valve carries out valve can be turned manually.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
