Embodiment
As shown in Figure 1.
Environment-friendly type cooling medium air-conditioning special valve is made of turncap 1, valve rod 2, sealed cap 3, seal ring 4, valve body 5, pad 6, bolt 7, joint 8, bonnet 9, rubber seal piece 10, attachment screw 11, single joint 12, sealant layer 13.
A kind of environment-friendly type cooling medium air-conditioning special valve, by turncap 1, valve rod 2, sealed cap 3, seal ring 4, valve body 5, pad 6, bolt 7, joint 8, bonnet 9, rubber seal piece 10, attachment screw 11, single joint 12, sealant layer 13 is formed, switch by valve rod 2 control service ports valve insides is realized ending of special valve and external channel and unlatching, valve rod 2 is installed in the valve body 5, two ports seal ring 4 is installed at valve body about in the of 5, pad 6, valve body 5 tops are equipped with sealed cap 3, sealed cap 3 compresses seal ring 4, turncap 1 is anchored on valve rod 2 ends by attachment screw 11, be connected with single joint 12 at valve body 5 sidepieces, valve body 5 bottoms are connected with bolt 7, be connected with joint 8 in the bolt 7, rubber seal piece 10 is installed in the joint 8, on joint 8, be set with bonnet 9, at valve body 5, bolt 7, joint 8, single joint 12 places of being connected to each other are provided with sealant layer 13.
Offer several grooves on the end face circumference of bolt 7, when valve rod 2 was screwed into extreme lower position, the groove position of offering on the bolt 7 made special valve still be connected the inside and outside, and when valve rod 2 was threaded to the extreme higher position, the inside and outside passage was cut off.
Described special valve is connected with service ports by bonnet 9, is the movable structure between bonnet 9 and the joint 8, and bonnet 9 compresses rubber seal piece 10 and service ports sealing.
Environment-friendly type cooling medium air-conditioning special valve is mainly used in R410a refrigerant installation of air conditioners, the maintenance process, use that this special use valve body vacuumizes, refrigerant can operation, the R410a refrigerant is the environment-friend substitution product of R22 refrigerant, R410a refrigerant air-conditioning system pressure is 4.15MPa, and R22 refrigerant air-conditioning system pressure is 2.94MPa.
High and the refrigerant use amount had relatively high expectations and the characteristics of environmental protection aspect according to R410a refrigerant air-conditioning system pressure, the product structure of special valve and technical characterstic are: be connected with service ports by bonnet 9, rubber seal piece 10 and service ports face seal, control the switch of service ports valve inside by the adjusting of a valve rod 2 height, valve body 5 and external channel by and open function.
When valve rod 2 is threaded to the extreme higher position,, the inside and outside passage is ended, play seal action by the seal action of pad 6.
When valve rod 2 is separated from the extreme higher position downwards when valve rod 2 is screwed into extreme lower position, special valve all is on state.
When service ports valve inside position is low, can normally open, when valve rod 2 is screwed into extreme lower position, still can guarantee that the inside and outside normally is communicated with by bolt 7 fluting positions for guaranteeing valve inside.
The thin bar in the bottom of valve rod 2 can carry out the pushing tow operation to valve spool on the refrigeration system, with realize refrigeration system under the complete closed state by special valve of the present utility model to refrigeration system on the spool of control valve carry out the pushing tow operation, to realize the spool opening and closing of control valve on the refrigeration system.
Special valve and service ports rely on bonnet 9 screw threads to be connected, and bonnet 9 structures adopt active connection, very conveniently during connection rely on rubber seal piece 10 to carry out with the sealing of service ports fast, and rubber seal piece 10 is changed and is very easy to.
Service ports is meant the working interface on the refrigeration system, typically refers to the connection mouth that is used to vacuumize with refrigerant can operation.
Refrigerant is meant the refrigeration agent that refrigeration is used in refrigeration system or the air-conditioning system, as R410a refrigerant, R22 refrigerant.
The bonnet 9 of special valve is connected with service ports, and compress rubber seal piece 10, make rubber seal piece 10 and service ports surface seal fully, then single joint 12 is connected with vacuumizing with the refrigerant filling apparatus, at first vacuumize operation, carry out the refrigerant can then, the refrigerant can finishes and closes special valve, closes the valve on the refrigeration system then.
When refrigeration system is installed, the special valve connection is gone up in the refrigeration system, carry out above-mentioned operation and can finish installment work.
When refrigeration system is keeped in repair, special valve connect is gone up in the refrigeration system, extract refrigerant earlier out, carry out system maintenance then, maintenance finishes and carries out above-mentioned vacuumizing with refrigerant can operation and can finish maintenance work.
Because during the refrigeration system installation and maintenance, at first use special valve to vacuumize the control that passes in and out with refrigerant, and be operation under the environment of complete closed, therefore can control refrigeration agent does not leak outside, play environment-friendly function, can prevent that high pressure R410a refrigeration agent from leaking outside to the harm of human body, simultaneously by regulating the high and low position of special valve valve rod 2, realize the control of refrigerant passage openings of sizes, thereby realize the consumption of more accurate control refrigeration agent.
