Description
Technical field
The present invention relates to a kind of rapid pipe joint, especially relevant with rapid pipe joint with air conditioner.
Background technique
Existing air conditioner with rapid pipe joint solved air conditioner when mounted indoor set be connected and the total coating process challenge with the quick of outdoor unit, as the patent No. is that ZL200420109858.3 discloses a kind of air conditioner rapid pipe joint, this rapid pipe joint has solved the fitting operation complexity that air conditioner exists when mounted preferably, connective stability is poor, freon problem such as leakage easily in copper pipe when inconvenient dismounting, maintenance and dismounting, maintenance.And for example the patent No. is that ZL200520115846.6 discloses the integrated type rapid pipe joint of a kind of air conditioner, and this rapid pipe joint has solved the total coating process complicated problems preferably, can reduce the general assembly cost, makes things convenient for general assembly producer, improves advantages such as complete machine quality.But above-mentioned rapid pipe joint is owing to normally adopt welding manner to be connected with the air-conditioning stop valve, plug body is an integral type, the fixed mandril axially locating is unreliable, design of Sealing Structure is unreasonable, exist the attended operation complexity, connection reliability is low, is difficult to maintenance, and deficiencies such as poor stability are tightly connected.
Summary of the invention
The purpose of this invention is to provide a kind of easy to connect reliable, but long service life, the reusable high sealing property air conditioner quick coupling of the good stability that is tightly connected are maintained in butt joint.
For achieving the above object, the present invention is achieved by the following technical solutions.Reusable high sealing property air conditioner quick coupling comprises plug body, spring seat I, spring I, movable push rod, positioning ring, metal o-ring, the socket attachment cap, sealing gasket, piston, piston packing, connecting body, spring seat II, spring II, fixed mandril and pipe arrangement, plug body is made up of socket and jointing, socket and jointing have O type groove I by being threaded at the junction point that is threaded, and are provided with O RunddichtringO I in O type groove I, be provided with air-conditioning stop valve joint in socket and be connected internal thread, have O type groove II in the connection internal threaded end, in O type groove II, be provided with O RunddichtringO II, be provided with outer-hexagonal in the socket outer ring, have groove at movable top club head and jointing contacting point, be provided with seal ring in the groove.
Described reusable high sealing property air conditioner quick coupling is positioned at spring seat II outer fix place and is provided with cotter pin on fixed mandril, have sunk seat cushion groove at pistons end, and sealing gasket is located in the sunk seat cushion groove.
Described reusable high sealing property air conditioner quick coupling, its sealing gasket adopts modified hydrogenated nitrile rubber, and metal o-ring adopts the Austenitic stainless steel material.
The present invention compared with prior art has the following advantages: (one) is because plug body is designed to be made up of socket and jointing two parts, make in the plug body Component replacing that when breaking down, can be easy to remove and repair, avoided scrapping of whole joint, realized the reusable of joint, reduce user cost, improved the life-span of joint; (2) be to combine owing to rapid pipe joint is threaded with the employing of air-conditioning stop valve, and design O RunddichtringO raising sealing, when having avoided high-temperature soldering, make to install to become convenient; (3) be fixed mandril to be carried out the axial restraint location, improved reliability of products with cotter pin; (4) be that sealing gasket is located in the sunk seat cushion groove, makes the sealing gasket positioning stablity reliable owing to have sunk seat cushion groove at pistons end; (5) be that sealing gasket adopts by adding zine oxide/methacrylic acid hydrogenated nitrile-butadiene rubber is carried out material after the modification, metal o-ring adopts Austenitic 00Cr19Ni10 stainless steel material, high temperature resistant, high pressure, oil resistant, the corrosion of anti-refrigeration agent and the aging quality resistance of product have been strengthened, thereby be applicable to refrigeration agents such as R410A, R407C better, the while also provides important assurance for the reusability and the high leak tightness of product.
