As preferably, also be provided with retaining valve on the described air intake lever.
The beneficial effect of the utility model patent: the utility model adopts repeatedly used butt-end packing technology, need not the packing material between screw thread, be applicable to all size pipe thread and other screw thread, sealing detection pressure can be up to 3.0Mpa, testing process is easy and simple to handle, and greatly reduce cost, and reduced damage to product, install safe and reliable.
[description of drawings]
Fig. 1 is the structural representation of the utility model central air conditioner cabinet-type air conditioner heat interchanger package seal checker.
[embodiment]
Consult Fig. 1, central air conditioner cabinet-type air conditioner heat interchanger package seal checker, comprise screw thread fixation kit, air intake lever 7, gland bonnet 4, threaded mandrel 6, the leading section of described air intake lever 7 is provided with gland bonnet 4, threaded mandrel 6 is socketed on the air intake lever 7, threaded mandrel 6 is connected with the screw thread fixation kit by external thread, and threaded mandrel 6 screws rearward end can withstand gland bonnet 4.Also be fixed with rubber blanket 3 on the described gland bonnet 4, this rubber blanket 3 adopts the nitrile rubber pad.Described screw thread fixation kit comprises internal thread overcoat 2 and sealing socket 5, and the external thread of described threaded mandrel 6 is connected with the internal thread of sealing socket 5, and the internal thread of internal thread overcoat 2 is corresponding with close nipple 1 on the heat interchanger.Adopt junction of the edges of two sheets of paper screw 9 to be locked between described internal thread overcoat 2 and the sealing socket 5.Press the screw thread specification machining internal thread overcoat 2 of the close nipple 1 on the heat interchanger, this internal thread overcoat 2 is mainly used in the reacting force that bears gases at high pressure, and this internal thread overcoat 2 need only screw or use small wrench to screw a little by hand during work.The air intake lever 7 that has retaining valve 8 is connected with gland bonnet 4, is the nitrile rubber pad that seals before the gland bonnet 4.What propelling gland bonnet 4 and rubber blanket 3 sealed is threaded mandrel 6, and this threaded mandrel 6 adopts the closely-pitched threads to be connected with sealing socket 5, so that nitrile rubber pad stabilized seal.
Threaded mandrel 6 is that gland bonnet 4 and sealing socket 5 can or not cut brokenly by the mouth of pipe to guarantee rubber blanket 3 with threaded mandrel 6 rotations in seal process with the reason of gland bonnet 4, sealing socket 5 splits design, and seal gasket can use repeatedly.For preventing the rotation of gland bonnet 4 and rubber blanket 3, can adopt following two kinds of structures: a kind of is that threaded mandrel 6 is socketed on the air intake lever 7 rotatably, and gland bonnet 4 is fixedlyed connected with air intake lever 7, and under threaded mandrel 6 rotated, air intake lever 7 and gland bonnet 4 did not rotate.Another kind is that threaded mandrel 6 is fixedly sleeved on air intake lever 7, and gland bonnet 4 is arranged on the air intake lever 7 rotatably, rotates at threaded mandrel 6 and can drive air intake lever 7 rotations, and gland bonnet 4 does not rotate.
The course of work: earlier with in the internal thread overcoat 2 precession close nipples 1, up to screwing.Because sealing socket 5 adopts junction of the edges of two sheets of paper screw to be connected with internal thread overcoat 2, threaded mandrel 6 begins to turn clockwise this moment, gland bonnet 4 is subjected to compressing of threaded mandrel 6 and promotes to seal nitrile rubber pad 3 to contact with close nipple 1 end face and seal, because of being subjected to the pressure of threaded mandrel 6, can't and then rotate 4 of gland bonnets, therefore rubber blanket is directly sealed close nipple 1, and high pressure gas is injected gases at high pressure by retaining valve 8 and air intake lever 7 in system.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
