Embodiment
Embodiment one
As shown in Figure 2; for connecting a connection set for valve before gas cooker and stove, it comprises nut 7,7 ' and two red copper seal guide sleeve 6,6 ' that stainless steel lasso 3,3 ', two stainless steel protection overcoats 4,4 ', two links 5,5 ' and two that a corrugated stainless steel tubing 1, PVC for the protection of corrugated stainless steel tubing 1 protects teleflex 2, two auxiliary corrugated stainless steel tubings 1 to weld with link 5,5 ' argon welding have thickness pitch thread.Described coarse thread 702 pitch with the nut 7,7 ' of thickness pitch thread is 2-3 times of fine thread 703, and coarse thread 702 spiral shell footpath is less than fine thread 703.Described link 5,5 ' be three layers stepped, bottom section 503 is connected with corrugated stainless steel tubing 1, and middle interval 502 is the anistree holding part of rhombus, and high interval is outside thread linkage section 501.
Two links 5,5 ' are plugged in corrugated stainless steel tubing 1 two ends respectively, overlap stainless steel sleeve circle 3,3 ' outward at port again, by argon welding corrugated stainless steel tubing 1, link 5,5 ' and stainless steel lasso 3,3 ' be welding as one and form weld joint close seal 11 at jointing.Again two stainless steel protection overcoats 4,4 ' are enclosed within soldered interface position respectively, by card pressing tongs, stainless steel protection overcoat 4,4 ' card compressive strain are fixed on weld, play the effect of protection corrugated stainless steel tubing.
Finally two red copper seal guide sleeves 6,6 ' are placed into respectively in two tool withdrawal grooves 701 had between the coarse thread 702 of the nut 7,7 ' of thickness pitch thread and fine thread 703, then the port of nut 7, the 7 ' fine thread 703 two with thickness pitch thread screws respectively on the outside thread linkage section 501 of the stainless steel closely-pitched external thread connector 5,5 ' at stainless steel corrugated flexible hose 1 two ends.
Installation attended operation (use) process of the present invention is as described below:
First by the nut 7 with thickness pitch thread of corrugated stainless steel tubing 1 two ends connection, 7 ' revolves to move back and unloads, check the nut 7 with thickness pitch thread, with or without neglected loading red copper seal guide sleeve 6 in the tool withdrawal groove 701 of 7 ', confirm do not have neglected loading and installation direction errorless after, then there is the nut 7 of thickness pitch thread, the screw thread of 7 ' evenly coats aerobic sealing gel coating 12, or aerobic sealing gel coating 12 is evenly coated at the screw thread position of the screw thread position of valve 8 connecting port and the combustion gas input port of gas cooker 10 before the stove of the gas pipeline that need connect, the nut 7 of thickness pitch thread will be had again, the fine thread 703 hole bit alignment of 7 ' be connected with corrugated stainless steel tubing 1 link 5, the port head of the outside thread linkage section 501 of 5 ', turn clockwise and there is the nut 7 of thickness pitch thread, 7 ' the outside thread linkage section 501 being screwed into link 5, screw and make outside thread linkage section 501 top push up red copper seal guide sleeve 6 (to there is the nut 7 of thickness pitch thread, 7 ' stretches out outside thread linkage section 501 end and covers middle interval one segment distance) till.And then will the nut 7 of thickness pitch thread be had, before 7 ' the other end coarse thread 702 aims at the stove of gas pipeline, normal mounting is carried out in the connecting port of valve 8 or gas ring 10, after connection, be rotated counterclockwise the nut 7 with thickness pitch thread, 7 ', because the pitch of thickness tooth is different, make link 5, 5 ' with the stove of gas pipeline 9 before valve 8 or the coaxial rotating Vortex of gas ring 10 chase after into, screw into the nut 7 with thickness pitch thread, during 7 ' middle part, before the stove of gas pipeline 9 output tube of valve 8 or gas ring 10 port by be placed in the nut 7 with thickness pitch thread in advance, red copper seal guide sleeve 6 in 7 ', 6 ' contact, and with link 5, the port of 5 ' mutually dock chase after sting closely sealed, form first sealing Leakproof connection structure, also make the nut 7 with thickness pitch thread simultaneously, 7 ' corresponding being rotated in place and tightening.Aerobic sealing gel coating 12 is rotating in the process that is screwed into, be filled into there is thickness pitch thread nut 7,7 ' and link 5,5 ' in the gap everywhere that is connected of external screw thread, solidify within a certain period of time, the effect that second seals anti-leak is played in formation.Thus thoroughly avoid operator in installation process, because of omit install rubber seal or or the aging breakage of seal ring, or cause the danger of gas leakage because of the aging breakage of soft rubber fuel tube.
Although invention describes with reference to the above embodiments; but those of ordinary skill in the art very clearly can recognize that above embodiment is only for illustration of invention completely; wherein can make various changes and revise and not depart from invention in a broad sense; so not as the restriction to invention; as long as in essence of an invention scope, the change of above-described embodiment, distortion all will be fallen within protection domain that invention requires.
