Description

Connect stop valve and the pipe joint of adapter

Technical field

It the utility model is related to a kind of connector of pipeline；More particularly in a kind of air-conditioning duct by stop valve and adapter The pipe joint connected as one.

Background technology

Existing air-conditioning duct uses two kinds of attachment structures, and one kind is welding manner, and another kind is horn mouth connected mode.Loudspeaker For mouth connected mode using hard sealing, but during actual installation, outdoor unit installs people because space limits or work high above the ground Member is difficult to be installed according to being actually needed torque, easily causes liquid leakage, while is also later maintenance, changes and bring very Big inconvenience.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of install convenient, is easily changed and the general of soft seal The pipe joint that stop valve and adapter connect as one.

Technical scheme is used by the utility model：A kind of pipe joint for connecting stop valve and adapter, pipe joint include, Sealing ring, pad, jump ring and the stop collar being sequentially arranged in stop valve adapter hole；Adapter is sent into stop valve by pressure head and taken over Stop valve and adapter are fastened as a whole by Kong Zhong, nut.

The sealing ring tensioner is in the outer peripheral face of adapter, formation sealing；The pad is placed between sealing ring and jump ring, pad Piece limits the position of sealing ring, prevents jump ring from destroying sealing ring.

The elasticity of the jump ring will take over reverse elastic compression.

It is described it is spacing be placed between jump ring pressure head, stop collar to jump ring carry out it is spacing.

The pressure head is interference fitted with stop collar.

The pressure head is glued with stop collar.

The pressure head includes auxiliary section and press section, and the auxiliary section is interference fitted with stop collar, outside the press section Footpath is more than the internal diameter of nut end endoporus.

The cross section of the press section is oval.

The height of the auxiliary section is more than the height of nut end.

The external diameter of the press section is more than the external diameter of nut.

The beneficial effects of the utility model are：Adapter can be easily directly inserted into stop valve adapter hole, and by connecing Sealing ring tensioner is formed and sealed by pipe；Conversely, being exerted a force to pressure head outer end, pressure head presses the inside swell of jump ring inner ring, adapter not by Jump ring thrust, therefore, pull-out can be directly will take over, the defects of design of the pipe joint compensate for prior art, good seal, together When for the later stage maintenance, change provide conveniently.

50. the stop valve 80. of 60. nut of pressure head 70. is taken over.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description：

As shown in Figure 1 to Figure 3, the utility model connection stop valve and the pipe joint of adapter are used in air-conditioning duct, and pipe connects Head includes, and sequentially has sealing ring 10, pad 20, jump ring 30 and stop collar 40 in stop valve adapter hole；Adapter passes through Pressure head 50 is sent into stop valve adapter hole, and stop valve 70 and adapter 80 are fastened as a whole by nut 60.

The tensioner of sealing ring 10 adapter outer peripheral face, formed sealing, avoid the leakage of liquid in pipeline；The pad 20 are placed between sealing ring 10 and jump ring 30, and pad 20 limits the position of sealing ring 10, prevent jump ring 30 from destroying sealing ring 10；Institute The elasticity for stating jump ring 30 will take over reverse elastic compression；The stop collar 40 is placed between jump ring 30 and pressure head 50, stop collar 40 Jump ring 30 is carried out spacing.The pressure head is interference fitted with stop collar or pressure head is glued with stop collar, prevents pressure head from dropping out.

As shown in figures 4 a and 4b, pressure head 50 includes auxiliary section 51 and press section 52, the auxiliary section and stop collar interference Coordinate, the external diameter of the press section is more than the internal diameter of the endoporus 62 of nut end 61, is easy to press pressure head with hand, the press section Cross section is oval；The height of the auxiliary section is more than the height of nut end.Preferably, the external diameter of the press section is more than The external diameter of nut.

Operation principle of the present utility model is：Red copper adapter is inserted directly into stop valve by pressure head hole and taken in hole, in advance Realize that sealing is expected by the effect of copper tube expanding force installed in the sealing ring that stop valve is taken in hole, red copper adapter passes through bullet The property reverse elastic compression of jump ring is on stop valve；When needing to safeguard or changing red copper adapter, press, press in pressure head outer end Head presses the inside swell of jump ring inner ring, takes over not by jump ring thrust, can directly pull it, when pressure head external force discharges, pressure Head is resetted by elastic circlip, and stop collar carries out spacing to jump ring.

The utility model adapter can be easily directly inserted into stop valve adapter hole, and by taking over sealing ring tensioner Form sealing；Conversely, being exerted a force to pressure head outer end, pressure head presses the inside swell of jump ring inner ring, adapter not by jump ring thrust, because The defects of this, can directly will take over pull-out, and the design of the pipe joint compensate for prior art, good seal, while be the dimension in later stage Repair, change provide conveniently.
