Abstract
The utility model provides an integral fast coupler disconnecting valve, which is characterized in that one end of a hollow pipe joint is matched with a refrigerating fluid connecting pipe, the pipe joint is internally provided with a plug and a spring as well as a spring stator, and the other end of the pipe joint is connected with the disconnecting valve. The integral fast coupler disconnecting valve has the technical proposal that the pipe joint can be made into a box joint or a pin joint, one end of the pipe joint is connected with the refrigerating fluid connecting pipe, the other end is directly connected with the disconnecting valve, and the disconnecting valve is connected with the indoor unit or the outdoor unit of a detachable air conditioner. The disconnecting valve has the following advantages: firstly, the structure of the fast coupler is simplified, the parts are reduced, and the cost is decreased; secondly, a user needs not to connect the fast coupler and the disconnecting valve, the installation workmanship is omitted, and the labour cost for the installation is saved; thirdly, the phenomena existing in the prior art that the connecting part of the disconnecting valve and the detached fast coupler leaks easily, and the cracking happens due to the facts that the disconnecting valve and the detached fast coupler are longer and heavy, the force moment of the coupler is large, and the air conditioner vibrates during the running, etc. are overcome.
Description
Technical field
The utility model relates to disjunctor rapid pipe joint stop valve, is applicable to detachable air conditioner, belongs to field of air conditioning.
Background technique
Detachable air conditioner is divided into indoor set and outdoor unit, and the coolant connecting tube is arranged between two machines, and connecting tube needs jointing and stop valve.Installation at its air conditioner of country such as America and Europe must professional assembler could be installed, and expense is very high, so air conditioner factory has developed rapid pipe joint in recent years, operation such as need not vacuumize when mounted, simplified installation procedure, even the user can both install voluntarily.Existing employing is monomer rapid pipe joint, monomer rapid pipe joint is made up of a female joint and a tool joint pin, mix stop valve again after during use the male and female joint being connected to rapid pipe joint, therefore, the shortcoming that existing monomer rapid pipe joint technology exists is that accessory is many, the processing trouble, the purchase cost height is installed and still to be seemed loaded down with trivial details, and the joint between stop valve and rapid pipe joint is leaked easily and vibrated and cause fracture.
Summary of the invention
The purpose of this utility model is to have the shortcoming that monomer rapid pipe joint exists in order to overcome, and provides a kind of Component few, and cost is economized, and connection reliability is good, disjunctor rapid pipe joint stop valve easy for installation.
The technological scheme of the utility model disjunctor rapid pipe joint stop valve is: it is characterized in that a hollow tube joint that cooperates with the coolant connecting tube, obstruction and spring and spring fixed plate are installed in the pipe joint, the other end of pipe joint is connected with stop valve.
Disjunctor rapid pipe joint stop valve of the present utility model, its pipe joint can be made into female joint or tool joint pin, and of pipe joint links to each other with the coolant connecting tube, and the other end directly connects stop valve, and stop valve connects the indoor set or the outdoor unit of detachable air conditioner.The technical program one is a structure of having simplified rapid pipe joint, has reduced parts, reduces cost; The 2nd, the user does not need to carry out being connected of rapid pipe joint and stop valve again, omits installation procedure, saves labour cost is installed; The 3rd, having overcome has technology to leak easily at stop valve and monomer rapid pipe joint joint, and because both length are longer, Heavy Weight, joint moment is big, and the vibration that adds the means for air conditioner operation produces phenomenons such as fracture.
Disjunctor rapid pipe joint stop valve of the present utility model, its pipe joint is to be threaded with stop valve, and seal ring is installed in the threaded connection place, is threaded and uses flexibly, needs seal ring in the joint, good sealing effect.Its pipe joint and stop valve are to be welded to connect, and be welded to connect all to scrap after part is damaged, but connection reliability are good.
Description of drawings
Fig. 1 is the utility model disjunctor rapid pipe joint stop valve structure schematic representation.
Embodiment
The utility model relates to a kind of disjunctor rapid pipe joint stop valve, as shown in Figure 1, it is characterized in that a hollow tube joint 1 that cooperates with the coolant connecting tube, obstruction 6 and spring 2 and spring fixed plate 5 are installed in the pipe joint, the other end of pipe joint 1 is connected with stop valve 4.Its pipe joint 1 can be made into female joint or tool joint pin, what described female joint was connected with stop valve is female thread, what described tool joint pin was connected with stop valve is external screw thread, be female joint as shown in Figure 1, one of pipe joint links to each other with the coolant connecting tube, the other end directly connects stop valve, and the concrete structure of stop valve belongs to prior art, and stop valve connects the indoor set or the outdoor unit of detachable air conditioner.The technical program one is a structure of having simplified rapid pipe joint, has reduced parts, reduces cost; The 2nd, the user does not need to carry out being connected of rapid pipe joint and stop valve again, omits installation procedure, saves labour cost is installed; The 3rd, overcome prior art and leaked easily at stop valve and monomer rapid pipe joint joint, and because both length are longer, Heavy Weight, joint moment is big, and the vibration that adds the means for air conditioner operation produces phenomenons such as fracture.Its pipe joint 1 is that screw thread 7 is connected with stop valve 4, and seal ring 3 is installed in the threaded connection place, is threaded and uses flexibly, and seal ring, good sealing effect are installed in the joint.Its pipe joint 1 is to be welded to connect with stop valve 4, be welded to connect all to scrap after part is damaged, but connection reliability is good.
Claims (3)
