Fig. 1 is structural representation of the present utility model.
In figure, 1-by-passing valve, 2-water intaking valve, 3-filter, 4-hot type self-supporting temperature-sensing valve, 4 '-cooling type self-supporting temperature-sensing valve, 5-fan coil, 6-inlet channel, 7-water return pipeline, 8-gauge tap, 9-self-holding electromagnetic valve, 10-back-water valve (BWV).
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
As shown in Figure 1, the energy-saving type fan coil pipe control device that the utility model provides, comprise fan coil 5, inlet channel 6 is connected with fan coil 5 respectively with water return pipeline 7, between inlet channel 6 and water return pipeline 7, by-passing valve 1 is installed, water intaking valve 2 and Y type water filter 3 are installed on inlet channel 6, back-water valve (BWV) 10 is installed on water return pipeline 7, self-supporting temperature-sensing valve group is also installed on inlet channel 6, and self-supporting temperature-sensing valve group is formed in parallel by hot type self-supporting temperature-sensing valve 4 and cooling type self-supporting temperature-sensing valve 4 '.Between the back-water valve (BWV) 10 of water return pipeline 7 and fan coil 5, self-holding electromagnetic valve 9 is also installed, between self-holding electromagnetic valve 9 and fan coil 5, gauge tap 8 is installed.
Hot type self-supporting temperature-sensing valve 4 and cooling type self-supporting temperature-sensing valve 4 ' are indirectly-acting self-supporting temperature-sensing valve.Self-supporting temperature-sensing valve group can be arranged between water intaking valve 2 and Y type water filter 3, also can be arranged between Y type water filter 3 and fan coil 5, like this, by self-operated type, regulate and control the discharge that can control inlet channel 6, and then realize room temperature control comparatively accurately.
The work characteristics of direct-operated regulator: self-contained pressure regulator is without external energy, can be in the place work without gas without electricity, not only convenient but also saved the energy.Pressure segmentation limit is thin and cross one another, and degree of regulation is high.Be widely used in the automatic control of gas, liquid and steam medium pressure-reduced and-regulated or pressure release voltage stabilizing.This control valve is divided into again two kinds of direct acting type and indirect acting types.Direct acting type is called again load on spring formula, and flexible unit, as the thermometer bulb of part spring, bellows, bellows-type etc., utilizes the principle of elastic force and feedback signal balance in its structure.Indirect acting type control valve, it plays the amplification of feedback signal then by executing agency to have increased a pilot valve (pilot valve), drives the motion of main valve flap to reach the object that changes valve opening.
Self-supporting temperature-sensing valve group adopts special temperature-sensing probe, temperature-sensing probe is fixed on indoor return air inlet place, during winter heating, the indirectly-acting hot type self-supporting temperature-sensing valve 4 of often opening independently moves, can set 20 ℃ of return air temperatures, when return air temperature is during higher than 20 ℃, hot type self-supporting temperature-sensing valve 4 starts to close, when return air temperature reaches 25 ℃, close completely.Summer, while freezing, normally closed indirectly-acting cooling type self-supporting temperature-sensing valve 4 ' independently moved, and set 25 ℃ of return air temperatures, when return air temperature is during higher than 25 ℃, and cooling type self-supporting temperature-sensing valve 4 ' valve opening.The two in parallel use, when summer air-conditioning is opened, room temperature is generally greater than 25 ℃, and now cooling type self-supporting temperature-sensing valve 4 ' is opened, and hot type self-supporting temperature-sensing valve 4 full cut-offs realize refrigeration; During winter heating, room temperature is lower than 20 ℃, now hot type self-supporting temperature-sensing valve 4 standard-sized sheets, and cooling type self-supporting temperature-sensing valve 4 ' full cut-off, thereby realize, valve is in parallel to be used without conflict, realizes smoothly heating and refrigeration, makes indoor temperature progressively be stabilized to design temperature.
Before the back-water valve (BWV) 10 of water return pipeline 7, install self-holding electromagnetic valve 9 additional, can realize the energy-saving effect in zero load situation.Self-holding electromagnetic valve 9 has two coils, and its operation principle is: after loop A energising, open magnetic valve, and then power-off, magnetic valve still stays open state; After coil B energising, closed electromagnetic valve, then power-off, magnetic valve keeps closed condition.9 of self-holding electromagnetic valves need moment energising to complete valve switch action, and spool position does not need to continue electricity consumption and keeps.Its effect is: after opening, open in the water route of the fan coil of flowing through, and realizes normal circulation; After closing, fan coil water route is closed, and there is no current through fan coil 5.Because fan coil 5 critical pieces are copper pipe+radiating fin, turn off merely motor, can not stop current to continue circulation in fan coil 5, thereby make fan coil 5 become the common high-order radiator of installing, in the situation that not needing load, cause heat or loss of refrigeration capacity.Compared with general magnetic valve, it does not need to keep for a long time energising, almost there is no the consumption of electric weight simultaneously.
Self-holding electromagnetic valve 9 and fan coil 5 are controlled by gauge tap 8.The gauge tap 8 of prior art is third gear control, owing to having increased self-holding electromagnetic valve 9 in the utility model, needs the open and close action of two coils of two live wire control, makes gauge tap 8 functions become five grades of controls.
The energy-saving type fan coil pipe control device that the utility model provides, is applicable to the central air conditioner system of using end to be fan coil, particularly practical to the building of opening for non-24 hours and the building of carrying out cold and hot metering.
Above-described is only preferred embodiment of the present utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all can realize the purpose of this utility model, all should be considered as protection domain of the present utility model.
