Abstract
The utility model relates to a sealing valve of a process pipe for a refrigerating system. A valve core is arranged in a valve body. A valve body through hole which has the same central line as the valve core is arranged on the lower part of the valve body, and the valve body through hole is communicated with the process pipe. A valve core head is arranged on the lower part of the valve core. A valve core through hole is arranged in the center of the valve core. The valve core through hole is passed out of the upper part of the valve core through one side of the lower part. A sealing screw is arranged on the upper part of the valve core through hole. A locking nut is arranged on the outer diameter of the valve core. The valve core head is arranged on the lower part. The utility model is convenient for various operation working of repairing the refrigerating system, measuring the inner pressure, evacuating, padding refrigerant, etc. The utility model is suitable for various refrigerating systems.
Description
The utility model relates to refrigeration system process duct sealing device, particularly a kind ofly is convenient to the refrigeration system process duct sealing valve that refrigeration system was found time, loaded refrigeration agent, measures operations such as refrigeration system internal pressure.
As everyone knows, refrigerating the process duct of refrigeration systems such as factory, various refrigerator, refrigerator-freezer, air conditioner at present, all is the blind pipe by the flat back of exclusive clamps clamp sealing.This process duct overhauls afterwards, when filling refrigeration agent, need amputate the flat sealing of folder position, afterwards, need press from both sides flat sealing again, operate cumbersome, and when sealing, also can cause oxide layer at pipe internal surface, oxide layer comes off, with flow of refrigerant, easily block filter screen and capillary tube, break down.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of refrigeration system of being convenient to measure internal pressure, find time, load the refrigeration system process duct sealing valve of operations such as refrigeration agent, maintenance.
For achieving the above object, feature of the present utility model is: be provided with spool 8 in the valve body 3, valve body 3 belows are provided with the valve hole 2 with spool 8 same center lines, be connected with process duct 1, spool 8 belows are provided with valve core head 4, spool 8 centers are provided with valve core through hole 7, by spool 8 tops through the below one side pass-out, valve core through hole 7 tops are provided with sealing screw 10.
The utility model valve body 3 can adopt carbon steel, stainless steel, plastics etc. to make, be provided with spool 8 in the valve body 3, spool 8 can adopt carbon steel, copper, stainless steel, plastics etc. to make, valve body 3 belows are provided with the valve hole 2 of spool 8 same center lines and are connected with process duct 1, valve hole 2 on the valve body 3 can be communicated with process duct 1 welding, also can adopt screw thread to be connected.Spool 8 can adopt screw thread equipped mutually with valve body 3, and spool 8 belows are provided with valve core head 4, and valve hole 2 can be opened or stop up to rotary spool 8, and for making valve core head 4 closed valve through holes 2 tighter, valve core head 4 can adopt rubber, plastic or other material to make.Spool 8 centers are provided with valve core through hole 7, by spool 8 tops through the below one side pass-out, rotary spool 8 is opened valve hole 2, can be connected with process duct 1.Valve core through hole 7 tops are provided with sealing screw 10, sealing screw 10 can be fastened on the valve core through hole 7 through sealing gasket 9, can further valve hole 2 and valve body 3 cavitys be sealed when valve core head 4 closed valve through holes 2, sealing gasket 9 can adopt flexible sealing packing rings such as rubber, plastics.For making valve core head 4 closed valve through holes 2 fastening, spool 8 external diameters are provided with locking nut 6, can lock spool 8, and locking nut 6 can be fastened on the valve body 3 through seal ring 5, can further seal valve hole 2 and valve body 3 cavitys.In the time of need opening the refrigeration system sealing valve, removal sealing screw 10 will be taken over and insert valve core through hole 7 tops, unscrew locking nut 4, rotational valve core 8, adapter can be communicated with process duct 1, behind the end of operation, and rotational valve core 8, make 3 valve core heads, 4 closed valve through holes 2, fastening locking nut 6, removal is taken over, fit sealing screw 10.
The utility model is convenient to refrigeration system maintenance, measure internal pressure, find time, load operations work such as refrigeration agent, is applicable to various refrigeration systems.
Description of drawings
