Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model pipeline switch valve;
Fig. 2 is the cross section structure schematic diagram of Fig. 1;
Fig. 3 is the structural representation of this Fig. 1 middle joint body.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is not only confined to embodiment.
Shown in composition graphs 1-Fig. 3, a kind of pipeline switch valve, has fittings body 1, and the side of described fittings body 1 is connected with adapter assembly 16, opposite side is connected with screw thread copper piece 7, and air-flow enters from adapter assembly 16, by fittings body 1, then enters screw thread copper piece 7.Towards the direction away from fittings body 1, adapter assembly 16 comprises seal ring 6, positioning ring 5, jump ring 4, guide sleeve 3 and release cover 2 successively.Fittings body 1 is rotatable with screw thread copper piece 7, and in the joint with fittings body 1, the side of screw thread copper piece 7 is also provided with gasket seal 8.
There is in fittings body 2 the cavity 1-1 vertically arranged, be provided with locating pad 15 bottom cavity 1-1, in the cavity 1-1 of locating pad 15 press-in connector body, make part side close contact, reach sealing.Spring 14 is connected with on the upside of locating pad 15, spring 14 upper end is connected with gasket seal 13, also be provided with in cavity 1-1 and rotate positioning core 11, the upper end rotating positioning core 11 protrudes from the top of fittings body 1, the upper end rotating positioning core 11 is provided with and rotates setting sleeve 10, and rotating setting sleeve 10 arranged outside has rotatable handle 9.Rotate the O type circle 12 being arranged with sealing outside positioning core 11, the described outer wall of O type circle 12 and the contact internal walls of cavity 1-1.
Fittings body 1 is provided with the first through hole 1-3 and the second through hole 1-2, the cavity 1-1 of fittings body 1 is communicated with adapter assembly 16 inside by the first through hole 1-3, and cavity 1-1 is communicated with screw thread copper piece 7 inside by the second through hole 1-2.And the first through hole 1-3 and the second through hole 1-2 shifts to install, both are not on a horizontal plane.
Cavity 1-1 inwall is also provided with step 1-4, in the vertical direction, and step 1-4 is between the first through hole 1-3 and the second through hole 1-2, and the upper end of gasket seal 13 is against on described step 1-4.Be positioned at the internal diameter of the cavity on the downside of step 1-4, be greater than the internal diameter of the cavity be positioned on the upside of step 1-4.
After rotatable handle 9, rotation setting sleeve 10, rotation positioning core 11 and fittings body 1 carry out special assembling, regulate rotatable handle 9, rotating positioning core 11 has advance and retreat function.Regulate rotatable handle 9, rotate positioning core 11 and enter (moving down in figure), back down gasket seal 13, thus reach switch and open wide function, air-flow enters in cavity 1-1 from adapter assembly 16, from the second through hole 1-2 inflow screw thread copper piece 7; Regulate rotatable handle 9 return again, spring 14 is jack-up gasket seal 13 upwards, withstands step 1-4 on the upside of gasket seal 13, and the cavity of the upper and lower both sides of step is sealed by gasket seal 13, and air-flow cannot circulate.
