Abstract
The utility model discloses a novel stop valve for an air-conditioner, which comprises a valve body and a quick connector, wherein the connecting end of the valve body is in sealed connection with the quick connector; the quick connector comprises a connector housing, a connector valve needle, a return spring and an external rubber ring; a valve port is arranged at the end part of the connector housing; the return spring is arranged in the valve cavity of the connector housing; and the connector valve needle is arranged between the valve body and the return spring. The utility model has the advantages that the production and the mounting efficiencies of the air-conditioner are improved; technical personnel can refill refrigerant conveniently; and cooling medium leakage can be prevented effectively.
Description
Technical field
The utility model relates to refrigeration technology field, more particularly, relates to a kind of air-conditioning stop valve.
Background technique
Stop valve is generally used for being connected of outdoor unit tracheae and indoor set connecting pipings (blister copper pipe).Like this, factory's refrigeration agent that can vacuumize and annotate for outdoor unit on request when air-conditioning dispatches from the factory is then through closing stop valve storage refrigeration agent.But vacuum pump can not directly be connected with stop valve and vacuumizes, need be on stop valve the joint of one of extra connection and vacuum pump pairing, also need take off joint after filling refrigerant, produce like this with regard to many several procedures, efficient is not high.
When maintenance indoor set and connecting pipings stop valve capable of using with refrigerant recovering in outdoor unit.When keeping in repair the refrigeration system of split-type air conditioner,, refrigeration system is connected with maintenance of equipment, accomplishes the refrigeration matchmaker's that finds time, annotates operation through stop valve.Equally, these operations also need be on stop valve corresponding joint of extra connection, operation need be taken off joint after accomplishing.
The seal approach of two existing stop valves is to lean on 0 shape rubber seal on the spool to realize with the sealing of body cavity and the seal with screwed joint between sealed cap and valve body, and be threaded owing to the gap between its sealing surface is bigger, sealability is poor.
The model utility content
To the deficiency of existing technology, a kind of air-conditioning stop valve is proposed at present, comprise valve body; Also comprise rapid pipe joint; The connecting end and the rapid pipe joint of said valve body are tightly connected, and said rapid pipe joint comprises joint shell, joint needle, Returnning spring, external cushion rubber, and the end of said joint shell is provided with valve port; Said Returnning spring is arranged in the valve pocket of joint shell, and said joint needle is located between valve and the Returnning spring.
Said rapid pipe joint is threaded with valve body, and the body place is provided with O-ring seal third being threaded.
The connecting end of valve body is provided with the spring limit dais, and said Returnning spring one end is pressed on the spring limit dais, and the other end is pressed on the joint needle.
Said joint needle top is a frustum, and the valve port of said joint shell is provided with the suitable conical surface in side with joint needle top round platform.
Said joint shell inside is provided with the needle limit dais, and said joint valve Aculeata is provided with the limited ring corresponding with the needle limit dais.
Said joint shell open top inboard is provided with first seal washer, and the bottom side of said needle limit dais is provided with second seal washer.
Said joint shell is provided with positioning convex ring, is used for external cushion rubber is fixed on joint shell.
The utlity model has following advantage:
1. improved the efficient of the production and the installation of air-conditioning;
2. make things convenient for the technician to fill refrigeration agent once more;
3. effectively prevent coolant leakage.
Description of drawings
Fig. 1 is the structural representation of existing air-conditioning stop valve;
Fig. 2 is the utility model air-conditioning stop valve structure schematic representation;
The parts that each label is represented in the accompanying drawing are following:
1. connecting end 5. spools 41. joint needles 42. first seal washers 43. second seal washers 44. Returnning springs 45. spring limit daiss 46. positioning convex rings 47. the 3rd seal washer 48. needle limit daiss of valve inside 2. valve bodies 3. copper pipes 4. valve bodies
Embodiment
As shown in Figure 1, general air-conditioning stop valve comprises connecting end 4, the spool 5 of valve inside 1, valve body 2, valve body, and stop valve is connected with the refrigeration system of air-conditioning through copper pipe 3.
As shown in Figure 2; The utility model is a kind of air-conditioning stop valve; The connecting end 4, the spool 5 that comprise valve inside 1, valve body 2, valve body; Also comprise rapid pipe joint, wherein, rapid pipe joint is by joint shell, joint needle 41, first seal washer 42, second seal washer 43, the 3rd seal washer 47, Returnning spring 44.Stop valve is connected with the refrigeration system of air-conditioning through copper pipe 3.The connecting end 4 of valve body is connected with the internal thread of rapid pipe joint through the interior outside thread of establishing.
Connecting end 4 inside of the valve body of the air-conditioning stop valve of the utility model are provided with spring limit dais 45, and Returnning spring 44 1 ends are pressed on the spring limit dais 45, and the other end is pressed on the joint needle 41.Joint needle 41 tops are round platform, and the joint shell open top is provided with and the suitable conical surface in its side, and inside is provided with the needle limit dais 48 corresponding with the tail structure of joint needle.Joint shell open top inboard is provided with first seal washer 42, and the bottom side of needle limit dais 48 is provided with second seal washer 43, and the connecting end 4 externally threaded bottoms of valve body are provided with the 3rd seal washer 47.Also be provided with positioning convex ring 46 on the joint shell, be used for external packing ring is fixed on joint shell.
The air-conditioning stop valve of the utility model need use when using that the negative joint corresponding with rapid pipe joint found time with other, filled equipment is connected.
During connection, the thimble in the negative joint presses down joint needle 41, and Returnning spring 44 stressed compressive deformations make joint needle 41 promote toward connecting end 4 directions of valve bodies, makes between connecting end 4 and the external world of valve body and forms path, the operation that can find time, fill this moment.When negative joint docked with rapid pipe joint, external packing ring (not shown) provides kept the stiction that negative joint is connected with rapid pipe joint, and fills the space between two joints, prevented that air from getting into or coolant leakage.
After operation was accomplished, negative joint was extracted, and the pressure of butt joint needle 41 disappears; At this moment, Returnning spring 44 discharges elastic potential energy, pushes joint needle 41 to the joint shell open top rapidly; Add and be about the thrust that 5 times of atmospheric refrigerant pressure are produced in the stop valve; Make joint needle 41 be close to first seal washer 42 and second seal washer 43, form dual sealing, prevent that effectively refrigerant from leaking from the joint shell open top.In addition, for preventing the air gap leakage of refrigerant, the 3rd seal washer 47 is set in the relevant position from screw thread between the connecting end 4 of fast interface and valve body.
