Embodiment
Referring to Fig. 1, the utility model embodiment gas utensil connects and comprises C type nut 1, seal ring 2, cone-shaped flange 3, male connection 4 with stainless steel ripple flexible pipe plug-in connecting device, described C type nut 1 is provided with the cavity 11 that cooperates with seal ring 2, be provided with the nut inner thread 12 that cooperates with male connection 4 outside threads 41 in the C type nut 1, cone-shaped flange 3 is inserted in male connection 4, seal ring 2 is installed in the cavity 11 of C type nut 1, and C type nut 1 is connected with male connection 4 screw-thread fit.
Be provided with projection 22 in the described seal ring 2 of present embodiment, help better to seal up fuel tube, the protection combustion gas is not easy to leak.
Present embodiment cone-shaped flange 3 is provided with flange horn mouth α, and flange horn mouth α is 31 °, and male connection 4 is provided with joint horn mouth β, and joint horn mouth β also is 31 °.
Present embodiment male connection 4 is provided with joint chamfering 42, and the angle of joint chamfering 42 is 30 °, and seal ring 2 is provided with seal ring chamfering 21, and the angle of seal ring chamfering 21 is 30 °.
Present embodiment is not change the coupling head that Green's joint of valve outlet port/kitchen range suction port designs before the kitchen range for changing stainless steel ripple flexible pipe.When Green's tip side is inserted into the C type nut 1 of stainless steel ripple flexible pipe plug-in connecting device and seal ring 2 when interior, when C type nut 1 and male connection 41 connected, seal ring 2 compressed distortion were held on Green's joint, reach the purpose of sealing.
During use, stainless steel ripple flexible pipe is inserted in two present embodiments, an end connects gas utensil, and the other end connects gas inlet, tightens C type nut 1 and gets final product.
Simple deformation or the combination of every the utility model embodiment technological scheme and technical characteristics all should be thought to fall into protection domain of the present utility model.
