Abstract
A horizontal type throttling device comprises a cylindrical container shell body, double-screw bolts, an electromagnetic valve I, an electromagnetic valve II, and connecting pipelines. Two ends of the cylindrical container shell body are sealed. An inlet pipe hole penetrating through the shell body is formed in one side of the shell body, an outlet pipe hole I penetrating through the shell body and an outlet pipe hole II penetrating through the shell body are formed in the upper portion of the shell body, and an outlet pipe hole III penetrating through the shell body are formed in the other side of the shell body. The outer groove surfaces of the double-screw bolts mounted in the shell body and the inner wall of the shell body form a spiral channel which is respectively communicated with the inlet pipe hole, the outlet pipe hole I, the outlet pipe hole II, and the outlet pipe hole III. The electromagnetic valve I is communicated with the outlet pipe hole I and the outlet pipe hole III through connecting pipelines. The electromagnetic valve II is communicated with the outlet pipe hole II and the outlet pipe hole III through connecting pipelines. Multiple-section type flow regulation can be achieved, pressure drop of fluid flowing in the throttling device is changed through turning on and turning off the electromagnetic valve I and the electromagnetic valve II according to different work conditions, and thus flow regulation is achieved. The horizontal type throttling device is further simple in structure, low in manufacturing cost, strong in practicability, free from parts which are easy to damage and good in throttling effects.
Description
Technical field
The utility model relates to a kind of horizontal throttling arrangement, specifically the horizontal throttling arrangement that uses in a kind of refrigeration system.
Background technology
In refrigeration system, throttling means that the liquid refrigerant that high side to low side is carried carries out flow-control and adjusting, thereby guarantees the pressure reduction of the required foundation of refrigeration system, to reach the requirement of cooling refrigeration.Usually the throttling arrangement that uses in the refrigeration system has capillary, orifice plate, and heating power expansion valve and electric expansion valve, capillary and orifice plate are the fixation type throttle device, heating power expansion valve and electric expansion valve are adjustable throttling arrangement.The fixation type throttle apparatus structure is simple, and is reliable, but flow fix, can not regulate according to the working conditions change situation, when the operation of refrigeration system off-design operating mode or unit unloading, system's refrigerating efficiency is relatively poor.Adjustable throttling arrangement has heating power expansion valve and electric expansion valve, and they can change flow system flow according to system conditions, and wherein electric expansion valve utilizes stepper motor to come the open degree of application valve body, and Flow-rate adjustment more accurately, rapidly.The structure of adjustable throttling arrangement is all very complicated, and moving component is many, damages easily.
The utility model content
The technical problem that the utility model need solve provides a kind of low-cost throttling arrangement of simple in structure, with low cost, the adjustable throttle amount for refrigeration system.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of horizontal throttling arrangement, the cylindrical vessel housing that comprises closed at both ends, be arranged on double-screw bolt and the connecting line and the magnetic valve one, the magnetic valve two that are arranged on the pipeline of housing inboard, be provided with the import pore that runs through housing at described housing one end, this housing sidewall is provided with outlet pore one and the outlet pore two that runs through housing, is provided with the outlet pore three that runs through housing at this housing other end.Described housing inboard is installed on double-screw bolt, and the outer well surface of this double-screw bolt and inner walls constitute a helical duct, this helical duct respectively with import pore and outlet pore one, outlet pore two, outlet pore tee joint.Described magnetic valve one is by connecting pipe and outlet pore one and outlet pore tee joint.Described magnetic valve two is by connecting pipe and outlet pore two and outlet pore tee joint.
The utility model can be realized the segmented Flow-rate adjustment, according to the required flow of equipment under the different operating modes, by switch electromagnetic valve one and magnetic valve two, change the length of fluid flow channel in throttling arrangement, and then change fluid by the pressure drop of throttling arrangement, thereby realize Flow-rate adjustment.
Description of drawings
Accompanying drawing 1 is the utility model cross-sectional view; Label acute pyogenic infection of finger tip in the accompanying drawing: 1-housing, 2-double-screw bolt, 3-outlet pore one, 4-outlet pore two, 5-magnetic valve one, 6-magnetic valve two, 7-outlet pore three, 8-import pore.
The specific embodiment
For the ease of those skilled in the art's understanding, be further described below in conjunction with the utility model of embodiment:
As shown in drawings, a kind of throttling arrangement for refrigeration system comprises housing 1, double-screw bolt 2, magnetic valve 1, magnetic valve 26, connecting line.Housing is the cylindrical vessel of closed at both ends, the housing one distolateral import pore 8 that runs through housing that is provided with, housing top is provided with the outlet pore 1 that runs through housing, outlet pore 24, housing with inlet tube nose end couple positioned opposite is set the outlet pore 37 that runs through housing is arranged; Double-screw bolt is installed in the housing and is attached on the inwall, and the outer well surface of double-screw bolt and inner walls constitute a helical duct, respectively with import pore, outlet pore one, outlet pore two, outlet pore tee joint; Magnetic valve one is by connecting pipe and outlet pore one and outlet pore tee joint, and magnetic valve two is by connecting pipe and outlet pore two and outlet pore tee joint.
The utility model is located in the refrigeration system between the condenser and evaporimeter, the liquid refrigerants that condenser comes out enters in the housing by the import pore, passage inside spin in double-screw bolt and inner walls formation flows, owing to the friction of vias inner walls and liquid refrigerants produces along the journey pressure drop, when pressure drops to a certain degree, the operative liquid refrigerant can flash distillation become gaseous state, and further hinders flowing of liquid refrigerants, thereby reaches the purpose of throttling.Also be provided with magnetic valve one and magnetic valve two on the utility model, magnetic valve one is by connecting line and outlet pore one and outlet pore tee joint, and magnetic valve two is by connecting line and outlet pore two and outlet pore tee joint.By opening magnetic valve one or magnetic valve two, can change the length of liquid refrigerants flow channel in throttling arrangement, the more short then pressure drop of length is more little, and flow is just more big.
Embodiment of the present utility model has designed three sections Flow-rate adjustment, but is not limited to three sections Flow-rate adjustment, by the change design, can realize the Flow-rate adjustment of multistage.
