Abstract
A special-shaped straight tube connector comprises a double-thread hexagon single connector, a sealing part, a connecting nut and a straight tube base. The straight tube base is engaged and fixed withthe double-thread hexagon single connector through the connecting nut, the sealing part is arranged between the double-thread hexagon signal connector and the straight tube base, the connecting nut is in threaded connection with the double-thread hexagon signal connector after fastening a flange end of the straight tube base, and the double-thread hexagon signal connector and the straight tube base are tightly pressed, engaged and fixed. The special-shaped straight tube connector resolves problems that a connecting structure of the existing air-conditioner refrigeration system can not meet refrigeration requirements of air-conditioners in a high-precision computer machine room, and has the advantages that the surface of a valve body is uniform in color without burning and peroxidation problems or welding, and the special-shaped straight tube connector is simple in structure, convenient in manufacturing and using and reliable in property.
Description
Technical field
The utility model relates to a kind of special-shaped straight connector, belongs to the refrigeration product technical field.
Background technique
The present air-conditioning refrigeration system that uses, mainly be by indoor evaporator, outdoor condenser and two refrigerant cycle connecting tubes constitute, two refrigerant cycle connecting tube one ends are connected with the indoor evaporator locknut, the other end is connected with outdoor condenser locknut, to realize the periodic duty of refrigeration system, but the place that the air-conditioning system of this linkage structure is had relatively high expectations for temperature control, but exist serious potential safety hazard, because the air-conditioning system of this linkage structure, because indoor evaporator, outdoor condenser has vibration when operation, the vibration when operation of particularly outdoor condenser is bigger, the fracture of refrigerant cycle connecting tube joint will appear like this, the problem of loosening and freezing medium leakage, cause the air-conditioning system fault, thereby cause the air-conditioning temperature control malfunctioning, will cause the accident for the higher occasion of air-conditioning usage requirement like this, air-conditioning system as high-precision computer room, because high-precision computer room is very high to the requirement of air-conditioning system, variation of temperature can not be above positive and negative one degree centigrade, so must guarantee to use more than 15 years after disposable the installing of high-precision computer room air-conditioning system, in 15 years, maintenance can not be arranged, fault can not be arranged, otherwise might cause the contingency of high precision computation machine room.
Summary of the invention
The utility model provides a kind of a kind of special-shaped straight connector of novelty, two refrigerant cycle connecting tubes adopt two ends to be welded to connect, be the structure technology that special-shaped straight connector connects in the middle of the pipe, realize that high-precision computer room air-conditioning system is disposable to install the purpose that no longer keep in repair in 15 years the back.
The technical solution adopted in the utility model is:
A kind of special-shaped straight connector, comprise: the single joint of two screw thread hexagonals, Sealing, attaching nut, straight tube seat, the straight tube seat cooperates fixing by the attaching nut with the single joint of two screw thread hexagonals, between single joint of two screw thread hexagonals and straight tube seat, be provided with Sealing, the attaching nut is connected with the single joint screw threads of two screw thread hexagonals after fastening the flange end of straight tube seat, and two screw thread hexagonals list joints and straight tube seat compression fit are fixed.
The single joint of two screw thread hexagonals is a pipe joint structure, and the centre is a through-hole structure, and outer wall is provided with the polygon structure of nut type, and it is fastening to be used for dismounting, and the end face that cooperates with the straight tube seat is provided with the installation annular groove of Sealing.
The straight tube seat is the pipe joint structure of flanged end, and the centre is a through-hole structure, the flange end of the straight tube seat sealing and fixing that matches with the end face that Sealing is housed of the single joints of two screw thread hexagonals.
The utility model beneficial effect is:
Owing to adopted a kind of special-shaped straight connector of the present utility model, the linkage structure that has solved existing air-conditioning refrigeration system is not suitable for the problem that high precision computation air conditioner in machine room refrigeration requires, a kind of special-shaped straight connector of the present utility model has: the valve body surface color evenly, do not have burn, snperoxiaized phenomenon, need not to weld, simple in structure, make characteristics easy to use, reliable performance.

Embodiment
As shown in Figure 1.
A kind of special-shaped straight connector, comprise: the single joint 1 of two screw thread hexagonals, Sealing 2, attaching nut 3, straight tube seat 4, straight tube seat 4 cooperates fixing by attaching nut 3 with the single joint 1 of two screw thread hexagonals, between single joint 1 of two screw thread hexagonals and straight tube seat 4, be provided with Sealing 2, attaching nut 3 is threaded with the single joints 1 of two screw thread hexagonals after fastening the flange end of straight tube seat 4, thereby the single joints 1 of two screw thread hexagonals are fixed with straight tube seat 4 compression fit.
The single joint 1 of two screw thread hexagonals is a pipe joint structure, and the centre is a through-hole structure, and outer wall is provided with the polygon structure of nut type, and it is fastening to be used for dismounting, and the end face that cooperates with straight tube seat 4 is provided with the installation annular groove of Sealing 2.
A refrigerant cycle connecting tube is divided into two, forms 2 half root refrigerant cycle connecting tubes, wherein an end and the indoor evaporator of half root refrigerant cycle connecting tube are welded to connect then, and an end interface of the other end and special-shaped straight connector is welded to connect; Then an end and the outdoor condenser with other half root refrigerant cycle connecting tube is welded to connect, and the other end is connected with the other end joint weld of special-shaped straight connector.
According to above-mentioned job step, adopt identical Placement to finish the connection work of another root refrigerant cycle connecting tube.
After then indoor evaporator, outdoor condenser being installed respectively, two refrigerant cycle connecting tubes are connected to each other with special-shaped straight connector, qualified on inspection, just can use by liquid feeding.
