Abstract
The utility model relates to a fan coil soft connecting head used for center air-conditioning air conditioners. Existing stainless steel corrugated soft joints are ordinary processed by stainless steel bands which are formed into tube blanks by argon arc welding and has short service life. The utility model comprises a heat resistance rubber tube and a metal net sleeve which is sheathed outside the rubber pipe. The utility model is characterized in that one end of the rubber sleeve is connected with a joint, the other end of the rubber sleeve is provided with a connecting member of which the outer end part is connected with a nut, a transition joint is screwed in the nut, the inner end parts of the joint and the connecting member both form an annular groove, the end parts of rubber pipe and the net sleeve are arranged in the annular grooves, and the rubber pipe and the net sleeve are connected with the side walls of the annular grooves by barbs. The utility model can bear larger operating pressure and has the advantages of convenient installation and use.
Description
Technical field
The utility model is a kind of central air-conditioner fan coil unit hose connector.
Background technique
Central air-conditioner fan coil unit soft connector, adopt the rubber soft connector the earliest, because there is withstand voltage low, shortcoming such as easily aging, working life is short in it, substituted by stainless steel ripple soft connector gradually in recent years, and stainless steel ripple soft connector generally adopts Stainless Steel Band to process after argon arc welding forms pipe, and weld seam is responsive to the chlorion in the water, particularly surpasses in the water of 25mpp at chloride ion content, weld seam is corroded easily, has influenced the working life of soft connector.
The model utility content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of fan coil unit soft connector that can bear big working pressure is provided, to prolong the working life of soft connector.
For this reason, the utility model adopts following technological scheme: the fan coil unit soft connector, comprise heat-resistant rubber hose and be enclosed within the outer metal net of sebific duct, it is characterized in that: an end of gum cover is connected with a joint, the other end is provided with a connection piece, the outer end of link connects a nut, and a transit joint is spirally connected in the nut; The inner end of joint, link all forms an annular groove, and the end of sebific duct and net places in the annular groove, and sebific duct, net are connected with hangnail with the annular groove sidewall.Heat-resistant rubber hose generally adopts EPDM pipe or heat-resisting plastic cement pipe, and net is formed by the Stainless Steel Wire braiding, after the end of sebific duct and net places annular groove, closes with withholding riveting by machine, and hangnail is combined securely with sebific duct and net.The utility model can bear bigger working pressure, and latus rectum can reach 6MPa at DN50 with interior soft connector bursting pressure, adopts high-quality EPDM sebific duct and Stainless Steel Wire, can bear hot and cold water in 120 ℃ and water vapor continuous operation more than 15 years, long service life.
Described fan coil unit soft connector has a circular groove that is used for the nut activity on the outer end of link, nut is limited in can not deviate from the circular groove and can rotate by compressive deformation, has made things convenient for the installation and the use of fan coil unit soft connector.
Described fan coil unit soft connector, the outer end sidewall of joint is provided with taper pipe thread, and the outer end of transit joint is provided with outer cone or endosiphuncular tube screw thread.Pipe thread is used for being connected with other pipe fitting.
Described fan coil unit soft connector is provided with a rubber cushion, the enhanced leaktightness performance between link and transit joint.
The utlity model has following effective effect: can bear bigger working pressure, latus rectum can reach 6MPa, long service life at DN50 with interior soft connector bursting pressure; Because an end has adopted the kink nut, has made things convenient for installation of the present utility model and use.
