Description
Technical field
The utility model relates to a kind of chiller plant accessory, specifically a kind of energy-conservation valve.
Background technique
Chiller plant is generally formed a totally enclosed refrigeration system by compressor, condenser, filter, capillary tube and vaporizer, its working principle is that compressor sucks compressor to the refrigeration agent that heat absorption in the vaporizer becomes low-pressure low-temperature gas by pipeline, and be compressed into high-pressure and high-temperature steam, be discharged to again in the condenser and prop up, thereby constantly reduce the interior temperature of refrigeration cabinet.
At present the filling refrigeration agent is general all have manometric stop valve to vacuumize from the process duct tipping of compressor after, the filling refrigeration agent, will prepare another compressor or vacuum pump so separately to system pump down, complicated, time is long again, and have and find time not cause only ice stifled, thereby the waste refrigeration agent is lost time.
In the leak detection of chiller plant with when repairing, generally all be from process duct Jia Biaojia valve, with another compressor or vacuum pump system is pressurizeed, stop to pressurize to the certain pressure scale, see whether the scale on the table has change, if constantly diminish, illustrative system is leaky.Can't tell this moment is that those parts in condenser, filter or the vaporizer are leaky, can only know roughly that system has parts leaky, gives leak detection and repairs and bring very big trouble.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency provides a kind of chiller plant energy-conservation valve.
The purpose of this utility model can be achieved through the following technical solutions:
The energy-conservation valve of a kind of chiller plant, comprise valve body, two three circulation passage are set in the valve body, be communicated with a passage between two three circulation passage, two three circulation passage all have two passages to lead to outside the valve body, establish T type three-way valve in one of them three circulation passage, lead to outer two passages in addition of valve body, one is steam outlet pipe, another passage is the connecting tube I, it is the refrigerant charging mouth that another three circulation passage is led to an outer passage of valve body, and another is the connecting tube II, on the refrigerant charging mouth one-way valve is set.
The energy-conservation valve of above-mentioned chiller plant also is provided with the pressure meter of being with valve on steam outlet pipe.
The energy-conservation valve of above-mentioned chiller plant, described one-way valve is a plunger.
Adopt technique scheme, the utility model is by following advantage: when filling refrigeration agent, the utility model is connected in series on the pipeline between compressor and vaporizer, conveniently fills refrigeration agent, and also easy to operate time saving and energy saving; In when leak detection,, the utility model is connected on the pipeline between the different parts in the equipment control three-way valve, the just leak detection of each parts in the realization equipment easily according to the parts difference of leak detection.The utility model is simple in structure, and utilization chiller plant self compressor can be realized different chiller plants are filled refrigeration agent or leak detection repairing, and operation is very easy.The utility model be fit to refrigerator, refrigerator-freezer and air-conditioning etc. chiller plant.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The energy-conservation valve of a kind of as shown in drawings chiller plant, comprise valve body 1, two three circulation passage 6 are set in the valve body 1,17, be communicated with a passage between two three circulation passage, two three circulation passage all have two passages to lead to outside the valve body, establish T type three-way valve 2 in one of them three circulation passage, lead to outer two passages in addition of valve body, one is steam outlet pipe 5, and another passage is a connecting tube I 15, and it is refrigerant charging mouth 3 that another three circulation passage is led to an outer passage of valve body, another is a connecting tube II 16, one-way valve 4 is set on refrigerant charging mouth 3, also is provided with the pressure meter 7 of band valve on steam outlet pipe, described one-way valve 4 is plungers.
Being communicated with between a passage and the steam outlet pipe 5 between two three circulation passage of the utility model has angle, and angle is the number of degrees arbitrarily, and optimum scheme is 90 degree.
Working procedure of the present utility model is as follows:
The utility model is in the application of chiller plant filling refrigeration agent, the energy-conservation valve of chiller plant is connected on the compressor and the pipeline between the vaporizer of chiller plant, use as the refrigeration agent charging point, twisting T type three-way valve, make compressor and vaporizer UNICOM, steam outlet pipe is closed, and annotates refrigeration agent until reaching requirement by the filling of refrigerant charging mouth.
The utility model at the energy-conservation valve of chiller plant in the optimum scheme of the application of chiller plant filling refrigeration agent is, emptying pipe at first before the filling refrigeration agent, promptly twist T type three-way valve, make UNICOM between steam outlet pipe and the vaporizer, separate between compressor and the vaporizer, open compressor, lower amount of refrigerant is annotated in the compressor by the refrigerant charging mouth, emptying pipe, twist T type three-way valve again, make compressor and vaporizer UNICOM, steam outlet pipe is closed, and annotates refrigeration agent until reaching requirement by the filling of refrigerant charging mouth.
The utility model chiller plant condenser leak detection: the pipeline A between condenser and the filter is blocked, the energy-conservation valve of chiller plant is connected on the pipeline, twisting T type three-way valve, steam outlet pipe, condenser and compressor are communicated, condenser and connecting tube II are obstructed, open compressor and be pressurized to certain pressure to system, close compressor then, it is dead to cut off weldering near the pipeline B of condenser, whether the counting on the detected pressures meter has change, if the counting on the pressure meter constantly diminishes, illustrate that condenser is leaky.
The leak detection of the utility model chiller plant vaporizer: the energy-conservation valve of chiller plant is connected between vaporizer and the compressor, on the steam outlet pipe of the energy-conservation valve of chiller plant, pressure meter is set, twisting T type three-way valve, make mutual UNICOM between compressor and the vaporizer, valve body and pipeline are obstructed, open compressor and pressurize to system, close compressor will be pressed close to the capillary pipe end of filter and be cut off weldering extremely then.Make the mutual UNICOM of capillary tube, vaporizer and steam outlet pipe, whether the counting on the detected pressures meter has change, if the counting on the pressure meter constantly diminishes, illustrates that vaporizer is leaky.
The utility model can also block the capillary pipe end of pressing close to filter, is that the capillary pipe end of pressing close to filter is installed a valve II, throttle down II.
