Abstract
The utility model relates to a rapid Freon-feeding testing valve for an air conditioner, comprising a valve body. The valve body is internally provided with a valve core comprising a head part and a post rod which are matched with the inner cavity of the valve body, wherein the head part of the valve core is matched with a first conical surface of the inner cavity of the valve body in a sealing way; the post rod penetrates through a spring, and the tail part of the post rod is fixedly connected with a fixed seat; one end of the spring tightly presses against a step of the inner cavity of the valve body, and the other end tightly presses against a step of the fixed seat; the fixed seat is arranged at the end part of the valve body; and a triangular rubber ring is arranged on a second conical surface of the inner cavity of the valve body matched with a copper connection of an indoor set. The utility model has the advantages of low cost, copper saving, automatic sealing, convenient use and test and high safety.
Description
(1) technical field
The utility model relates to the quick liquid feeding of a kind of idle call and detects valve.
(2) technical background
In the existing separate type air conditioner indoor set pipe-line system, the method of filling refrigeration agent is: connect the copper connecting tube nut and be with bell-mouthed being open to the custom on the joint of indoor set input connecting tube, fill refrigeration agent with the liquid feeding rifle again, it is dead after the filling copper pipe to be pressed from both sides flat weldering, with the medium in the sealing pipeline system.But, this liquid feeding method fastening strict to bell-mouthed copper pipe and union nut, in case fastening not tight, will cause the phenomenon of leakage; And adopt welding, the technology more complicated, in welding process, use Securities such as acetylene, oxygen dare not, the waste gas of generation is big to environmetal impact.
(3) summary of the invention
For overcoming the above-mentioned defective of prior art, the utility model proposes a kind of with low cost, save copper material, can seal voluntarily, easy to use, easy to detect, the safe quick liquid feeding of idle call detects valve.
The technical solution of the utility model is: the quick liquid feeding of idle call detects valve, comprise valve body, in the described valve body spool is housed, described spool comprises head and the push rod that cooperates with the inner chamber of described valve body, and described spool head cooperates with the conical surface seal of body cavity; Described push rod runs through a spring, and the afterbody of described push rod is fixedlyed connected with a fixed base, and an end of described spring pushes against the step of described body cavity, and the other end pushes against the step on the described fixed base, and described fixed seating is in the end of valve body; The junction surface that described body cavity cooperates with the copper sleeve of indoor set is equipped with the triangle rubber ring.
Further, there is the space end of described fixed cover and described valve body.
Further, the head of described spool is provided with seal ring.
Technical conceive of the present utility model is: described fixed base, spool, valve body is by the injection moulding once-through, assembly process of the present utility model is as follows: earlier the O type circle described spool head of packing into, described spool is put into valve body, the spring of on push rod, packing into, use the fixed base holddown spring, fixed base and push rod interference fit, with electric heating push rod is carried out again that secondary melts so that fixed base is fixedlyed connected with push rod, the triangle rubber ring of on body cavity and junction surface that the copper sleeve of indoor set cooperates, packing into again.
When to the indoor set liquid feeding, rapid pipe joint inserts the valve body afterbody, the head roof pressure fixed base of rapid pipe joint, and fixed base moves forward together with spool, and the spool head breaks away from the conical surface that is sealed and matched with body cavity, and this moment, spring was in compressive state.
When rapid pipe joint is taken away, then fixed base loses the pressure of roof pressure, and spring recovers deformation, promotes fixed base, spool and moves head up to spool to afterbody and contact identically with body cavity, seals thereby reach voluntarily.
The utility model also can be used for the air-conditioning aerating.
The utility model can also detect whether leakage of indoor set, and its method is: light press fit lid if having gas to ooze out illustrates that then indoor set does not have the phenomenon of leakage, if no gas oozes out, then illustrates to have the phenomenon of leakage; Easy to use, can reduce the maintenance rate in the machine using process.
The utlity model has: with low cost, save copper material, can seal voluntarily, easy to use, easy to detect, safe advantage.
(4) description of drawings
Fig. 1 is a sectional view of the present utility model
(5) embodiment
With reference to accompanying drawing, further specify the utility model:
The quick liquid feeding of idle call detects valve, comprises valve body 3, in the described valve body 3 spool 2 is housed, and described spool 2 comprises head 21 and the push rod 22 that cooperates with the inner chamber of described valve body 3, and described spool head 21 is sealed and matched with the conical surface 31 of body cavity; Described push rod 22 runs through a spring 6, the afterbody of described push rod 22 is fixedlyed connected with a fixed base 1, one end of described spring 6 pushes against the step 32 of described body cavity, and the other end pushes against the step 11 on the described fixed base 1, and described fixed base 1 is positioned at the end of valve body 3; The junction surface 33 that described body cavity cooperates with the copper sleeve of indoor set is equipped with triangle rubber ring 4.
Described fixed cover 1 has the space with the end of described valve body 3.
The head 21 of described spool 2 is provided with seal ring 5.
Technical conceive of the present utility model is: described fixed base 1, spool 2, valve body 3 is by the injection moulding once-through, assembly process is as follows: earlier the seal ring 5 described spool head 21 of packing into, described spool 2 is put into valve body 1, the spring 6 of on push rod 22, packing into, with fixed base 1 holddown spring 6, fixed base 1 and push rod 22 interference fit, carry out with electric heating again that secondary melts so that fixed base 1 is fixedlyed connected with push rod 22, the triangle rubber ring 4 of on body cavity and junction surface 33 that the copper sleeve of indoor set cooperates, packing into again.
When to the indoor set liquid feeding, rapid pipe joint inserts the valve body afterbody, the head roof pressure fixed base 1 of rapid pipe joint, and fixed base 1 moves forward together with spool 2, and spool head 21 breaks away from the conical surface 31 that is sealed and matched with body cavity, and this moment, spring 6 was in compressive state.
When rapid pipe joint is taken away, then fixed base 1 loses the pressure of roof pressure, and spring 6 recovers deformation, promotes fixed base 1, spool 2 and moves head 21 up to spool to afterbody and contact identically with body cavity, seals thereby reach voluntarily.
The utility model also can be used for the air-conditioning aerating.
The utility model can also detect whether leakage of indoor set, and its method is: light press fit lid if having gas to ooze out illustrates that then indoor set does not have the phenomenon of leakage, if no gas oozes out, then illustrates to have the phenomenon of leakage; Easy to use, can reduce the maintenance rate in the machine using process.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
