Abstract
The invention provides the capillary thermal regulating valve that a kind of suitable small refrigeration systems is used, its inner temperature sensing agent that injects, resistance when the outer surface by valve can be subjected to the influence of external temperature to change valve refrigeration agent is flow through, the present invention is installed on the muffler of refrigeration system, can obtain refrigerant flow changes and the effect of respective change with working condition, make system give full play to refrigerating capacity, thereby reduce the energy consumption of refrigeration system.
Description
The present invention relates to a kind of flow regulator of refrigeration system, the refrigerant flow controlling device that particularly a kind of suitable refrigerator, air conditioner are used.
In small refrigeration systems, capillary tube is used as the throttling device widely.It has advantages such as reliable operation, cost be low, easy for installation, but its resistance state can't regulate, the pressure difference at two ends is depended in the variation of flow.When outside air temperature variation or heat load variation, the variation of its flow can not be satisfied the requirement that working condition changes, and influences the performance of refrigerant system capacity, and energy consumption is increased.Existing heating power expansion valve can overcome this shortcoming, but its cost height, volume are big, should not use in small refrigeration systems.
The objective of the invention is to: provide a kind of and can regulate resistance state capillaceous by working condition automatically, thereby cut down the consumption of energy, the thermal regulating valve of energy saving.
Purpose is to realize like this, corresponding site in the middle of capillary tube disconnects, connecting one can be according to muffler automatic temperature control valve core position, thereby regulate the valve of resistance state, make the change of refrigerant flow satisfy the requirement that working condition changes, make refrigeration system always work in the lower state of energy consumption.
Use the controlling device that the present invention makes, compare with the device that only adopts capillary-compensated, has remarkable energy saving effect, because the present invention can shorten use length capillaceous effectively to offset departmental cost, and have little characteristics of volume, compare with existing heating power expansion valve, have advantages such as cost is low, easy for installation.
Below in conjunction with drawings and Examples the present invention is done detailed description.
The structural representation of Fig. 1 capillary thermal regulating valve
The content formula scheme of installation of Fig. 2 capillary thermal regulating valve
The outer-enwraped type scheme of installation of Fig. 3 capillary thermal regulating valve
Referring to Fig. 1, the profile of apparatus of the present invention is a cylindrical body, by front valve shell 1, regulates sealing screw 2, outer tube 3, and diaphragm 5, gland nut 7, slip pipe 11, spool 12, spring 13, rear valve body 14, capillary tube 15 is formed.Refrigeration agent flows into from the capillary tube 15 of front valve shell 1 left end, and by adjustable clearance 9, the hole 10 of spool 12 is from capillary tube 15 outflows of rear valve body 14 right-hand members.Temperature sensing agent injects annulus cylindrical space 6 and 19 by screw 2, and the two is 4 connections through the hole.Temperature sensing agent is subjected to the influence of external temperature by outer tube 3, makes its Volume Changes produce corresponding thrust on diaphragm 5, makes slip pipe 11 under the effect of spring 13, regulates the size in gap 9.
Valve body 1 and 14 is many stepped cylinder, and the two connects with thread seal with outer tube 3, and the internal connection compresses the outer circular edge of diaphragm 5, and the internal circle cause nut 7 of diaphragm 5 compresses.Diaphragm 5 is an arc-shaped surface with slip pipe 11 contacting points, and spring 13 is housed in the slip pipe 11, spool 12, and can move forward and backward along the axis of rear valve body 14, to regulate gap 9, change the resistance of valve convection cell.
Screw 2 promptly is the temperature sensing agent inlet, the also raised position of can regulate diaphragm 5, thus regulate the initial value in gap 9.Capillary tube 15 is respectively in two ends of valve body face cut-in valve.
Figure 2 shows that content formula installation method of the present invention, this valve 16 can all be installed in the inside of muffler 17, has temperature regulation performance preferably like this, but need connect a container on muffler specially; Also can be as shown in Figure 3, with the good material of heat-conducting property with muffler 17 parallel claddings together, equally also can obtain self-regulating function with this valve 16.
Claims (5)
1, a kind of capillary thermal regulating valve, the particularly a kind of valve that can regulate the resistance state automatically that changes according to the cooling condition condition.Its outer surface can be passed to the variation of external temperature inner temperature sensing agent, makes it promote valve core movement to change the resistance of valve convection cell; This valve can be installed in the position of energy perception refrigeration system muffler temperature, can be the content formula, also can be outer-enwraped type.
2, by the described valve of claim 1, it is characterized in that, by front valve shell 1, screw 2, diaphragm 5, nut 7, rear valve body 14 constitutes an enclosed space with storage temperature sensing agent of two-layer cylindrical toroidal and connection, and the volume in this space can change with external temperature; Diaphragm 5, slip pipe 11, spool 12, spring 13 formations are positioned at rear valve body 14 can slide vertically, regulates the movement means in gap 9.
3, by the described valve of claim 1, it is characterized in that outer tube 3 the same rear valve bodies employing thread seals connect into integral body, capillary tube 15 is respectively from the inside of both ends of the surface cut-in valve.
4,, it is characterized in that screw 2 promptly is the sealed mouth that injects temperature sensing agent, can be used to regulate the initial position in gap 9 again by the described valve of claim 1.
5, by the described valve of claim 1, it is characterized in that this valve can all be installed in the muffler, also can be installed in outside the muffler.
