Abstract
The invention relates to the technical field of valves, in particular to a heating ventilation temperature-control electric three-way valve used for controlling the opening of a cold water inlet and the opening of a hot water inlet in a heating ventilating system to ensure that water temperature at a water outlet is constant. The valve comprises a valve body. A valve bonnet is arranged above the valve body. A valve seat is arranged in the valve body and the valve bonnet. A three-way ball is arranged in the valve seat. The upper part of the three-way ball is connected with a valve stem. The upper end of the valve stem is connected with an electric actuator. The electric actuator is externally connected with a temperature controller. Aiming at the characteristics of the automatic full-closed loop feedback heating ventilation system, the heating ventilation temperature-control electric three-way valve can rapidly, accurately and conveniently regulate the temperature. Compared with the prior art, the invention has the advantages of reasonable design, high automation level and rapid and high-precision temperature regulation.
Description
Technical field
The present invention relates to valve technology field, specifically provide a kind of hot water or cold water's water intake aperture size of controlling in the HVAC system in the hope of guaranteeing the constant heating ventilation temperature-control electric three-way valve of water outlet water temperature.
Background technique
At present, more and more at the control valve of HVAC system, the research staff has developed the product of a lot of properties according to different demands.For example: the constant-temperature water mixing valve of now relatively being paid close attention to is exactly by setting hot water or cold water's water intake openings of sizes, guaranteeing to obtain temperature required water in the mixed water cavity of valve body.But along with the various accessories of HVAC progressively to automatic updating, the system automation degree is more and more higher, guarantees that product can be more accurate, finishes the temperature adjustment action more efficiently, and can monitor real-time regulated in real time.
Three-way valve mostly is machinery control at present, can't realize its purpose of control automatically.
Summary of the invention
The present invention be directed to above problem, a kind of heating ventilation temperature-control electric three-way valve is provided, it cooperates temp controller and electric actuator, utilize temp controller constantly to sample, handle field data, send control signal, make electric three passes ball valve motor operation or stop, the switching degree of control electric three passes ball valve has reached suitable temperature; When room temperature reached the temp controller setting temperature, temp controller made the outage of electric three passes ball valve, makes valve opening be in the optimum state, and room temperature remains in the temp controller setting temperature scope.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of heating ventilation temperature-control electric three-way valve, comprise valve body, described valve body top is provided with bonnet, be provided with valve seat in described valve body and the bonnet, be provided with the threeway ball in the described valve seat, described threeway ball top connects valve rod, and described valve rod upper end connects electric actuator, and described electric actuator is externally connected with temp controller.
The bonnet arranged outside has colored cap.
Be provided with O-ring seals between valve rod and the bonnet.
Be provided with O-ring seals between valve seat and the bonnet.
Be provided with pad between valve rod and the bonnet.
HVAC temperature control electric T-shaped valve of the present utility model, three discharge orifices of its threeway ball are vertical in twos, become the three-dimensional coordinate type, are built in the valve body, and by the valve base sealing that is installed on valve body and the bonnet, valve rod axis and water outlet dead in line have the sealing of O type circle on it.The valve rod lower end cooperates with the threeway ball, and the upper end cooperates with electric actuator, and electric actuator is connected by common port, opening end, closed end with temp controller.The flower cap mainly works to connect ball valve and electric actuator.
Valve ball in the tee ball valve generally can be divided into L type and T type, but in particular system (in the HVAC adjusting), T type ball valve regulating action is not obvious, belongs to direct ratio and regulates, and cold (heat) mouth of a river also increased when instant heating (cold) mouth of a river increased; L type valve ball uses comparatively complicated in this system, needs just can finish the supply effect of HVAC system through special processing.
Heating ventilation temperature-control electric three-way valve of the present invention, it is at the characteristics of automation full cut-off ring feedback HVAC system, can guarantee fast, accurately and easily temperature to be regulated, compared with prior art, its have reasonable in design, automaticity is high, the high characteristics of fast precision are moved in temperature adjustment.

Embodiment
Below in conjunction with the drawings and specific embodiments heating ventilation temperature-control electric three-way valve of the present invention is further described.
Shown in accompanying drawing 1-6, a kind of heating ventilation temperature-control electric three-way valve, comprise valve body 1, described valve body 1 top is provided with bonnet 2, be provided with valve seat 3 in described valve body 1 and the bonnet 2, be provided with threeway ball 4 in the described valve seat 3, described threeway ball 4 tops connect valve rod 5, described valve rod 5 upper ends connect electric actuator 6, and described electric actuator 6 is externally connected with temp controller 7.
Be provided with O-ring seals 9 between valve rod 5 and the bonnet 2.
Be provided with O-ring seals 10 between valve seat 3 and the bonnet 2.
Be provided with pad 11 between valve rod 5 and the bonnet 2.
This device can be divided into three actions after control: open, close, stop.When work two ultimate states being arranged, is respectively hot water end opening standard-sized sheet cold water end full cut-off (R state), hot water end full cut-off cold water end standard-sized sheet (L state).Setting by the R state to the L state-transition for closing, be unlatching by the L state to the R state-transition.In any case, the valve ball water outlet of threeway ball 4 and valve body water outlet remain standard-sized sheet.
As shown in Figure 7, this device is installed in the system, when temperature is lower than setting temperature, temp controller is given instruction of electric actuator, electric actuator drives valve rod control tee ball valve and opens, and this moment, temp controller continued Information Monitoring, reached predefined value until temperature, send halt instruction then, the threeway ball keeps current state constant; If temperature drift, temp controller can continue to instruction of closing of electric actuator, when arriving setting value, sends halt instruction.
Above-described embodiment, the present invention embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
