The quantity of said clamping pad is two, and described two clamping pads are the semicircle arcuation, and can complement each other to form an annulus.
The both sides of the exterior arc surface of clamping pad are equipped with chamfering, and this chamfering is extended along the circumferencial direction of clamping pad; The end face intersection of valve installation channel and joint body is provided with second chamfering; Second chamfering, taper hole are complementary with the chamfering of clamping pad both sides respectively.
Also be installed with the seal ring coaxial with the valve installation channel on the valve installation channel, an end of seal ring inserts in the annulus; The valve installation channel is provided with the seal groove that is complementary with the seal ring external diameter; The width of seal ring is greater than the length of seal groove.
The end that joint body is provided with the pipeline installation channel is provided with outside thread.
A kind of crossover sub that the utility model is set forth, its beneficial effect is:
1, this crossover sub is provided with seal ring, clamping pad, makes it have good sealing property, and guaranteeing does not have gas leakage, safe and reliable;
2, this crossover sub is through locking nut locking, and simple in structure, easy accessibility is convenient to safeguard.

Embodiment
Below, in conjunction with accompanying drawing and embodiment, a kind of crossover sub of the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
The preferred implementation of a kind of crossover sub of the utility model is like Fig. 1,2,3, shown in 4.Described crossover sub is used to connect the Green's formula air inlet nozzle and the fuel tube of gas range.This crossover sub comprises joint body 1 and is bolted in the locking nut 4 on the joint body 1.Locking nut 4 is the outer-hexagonal shape, and is provided with the tapped hole that extends along its axis.Certainly, the inventor is set to the outer-hexagonal shape with locking nut 4, and only for the ease of applying pretightening force, locking nut 4 can also be designed to cylindric or cone table shape according to actual conditions.This locking nut 4 also is provided with the taper hole 41 that is communicated with tapped hole, and end face taper hole 41 diameters from an end of tapped hole to locking nut reduce gradually.Joint body 1 is cylindric, and is provided with the cavity that runs through mutually with both ends of the surface.This cavity is provided with flange 15, can cavity be divided into valve installation channel 11 and pipeline installation channel 12 through flange 15.The external diameter of the internal diameter of valve installation channel 11 and Green's formula air inlet nozzle is complementary, and for Green's formula air inlet nozzle is locked, the end that joint body 1 is provided with valve installation channel 11 is provided with the outside thread that is complementary with tapped hole.The other end of joint body 1 also is provided with outside thread, so that the installation of fuel tube.The outer peripheral surface of joint body 1 is provided with chamfering 16, but deburring and be convenient to the installation in later stage.
This crossover sub also comprises the seal ring 2 that is installed on valve installation channel 11.Valve installation channel 11 is provided with the seal groove 14 that extends along its axis.The external diameter of the internal diameter of seal groove 14 and seal ring 2 is complementary, and the width of seal ring 2 is greater than the length of seal groove 14.
This crossover sub also is provided with two clamping pads 3.Described two clamping pads 3 are the semicircle arcuation, and can complement each other to form an annulus.The outer peripheral surface of the inner arc surface of clamping pad 3 and seal ring 2 is complementary.The both sides of the outer peripheral surface of clamping pad 3 are provided with chamfering 31, and this chamfering is extended along the circumferencial direction of clamping pad.Valve installation channel 11 is provided with chamfering 13 with the end face intersection of joint body 1.Chamfering 13, taper hole 41 are complementary with the chamfering 31 of clamping pad both sides respectively.In order to keep inside and outside unanimity, and have aesthetic property, also be provided with the conical surface 42 on the outer wall of locking nut 4, the conical surface 42 and taper hole 41 all are positioned at the same end of locking nut 4.
During use; Earlier clamping pad 3 couplings are an annulus; Be assemblied on the joint body 1, the end with seal ring 2 inserts in the annulus then, and the outer peripheral surface of seal ring 2 is matched with the inner arc surface of clamping pad 3; Again seal ring 2 is installed on the seal groove 14, and utilizes the hole of seal groove 14 and 11 formation of tracheae installation channel to take on seal ring 3 is carried out axially locating.Meanwhile, adjustment clamping pad 3 makes the chamfering 31 of clamping pad one side match with chamfering 13.Locking nut 4 is set on the joint body 1, the taper hole 42 of locking nut 4 and another chamfering of clamping pad is complementary, and can limits moving radially of clamping pad 3 through this.Again Green's formula air inlet nozzle is inserted on the valve installation channel 11 at last.When treating that Green's formula air inlet nozzle plug-in mounting puts in place, locking nut 4 is applied pretightening force, make its continuous screw-in, till the locking of Green's formula air inlet nozzle.Locking nut 4 can rotatablely move it and be converted into the straight line motion along axis in rotation, and drive taper hole 41 travels forward; Diameter owing to taper hole 41 reduces from inside to outside gradually again; So along with taper hole 41 travels forward, press on clamping pad 3, clamping pad 3 shunk through its inwall; Meanwhile, clamping pad 3 produces a radial force inwardly owing to deformation to seal ring 2, seal ring is inwardly shunk, and then Green's formula air inlet nozzle is tightened.Fuel tube then can be through nut check on pipeline installation channel 12.Through this mode, guaranteed that Green's formula air inlet nozzle is not pulled out, and do not had gas leakage to have good sealing property.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation all should belong to the protection domain of the utility model claim according to the technological scheme and the design of above description.
