Description
Technical field
The present invention relates to a kind of combustion gas Green crossover subs.
Background technique
Gas valve is a kind of safe corollary apparatus of gas pipeline engineering, for being truncated, being connected to, adjust gas in pipeline,
With good controlling and sealing performance is closed, existing gas valve includes single mouth gas valve and gas valve of speaking out of turn, single mouth combustion
Air valve is widely used on family's gas pipeline, with gas utensil (other gas utensils such as kitchen range, gas heater, gas firing wall)
Pipeline is connected, and gas utensil metal bellows generally uses metal bellows or hose, and metal bellows compares hose, can be effective
Avoid damaged by rats, the case where causing conduit failure of colliding with, the service life of lift line.
The interface of single mouth gas valve and gas utensil itself is had by taking single mouth gas valve as an example using spigot-and-socket joint structure
Body introduces spigot-and-socket joint: as shown in Figure 1, existing list mouth gas valve 1 includes valve body, spool, spigot-and-socket joint 11, spigot-and-socket is connect
First 11 are equipped with multiple tracks convex ribs 12, and 11 end of spigot-and-socket joint is additionally provided with the conical surface, and (interface of gas utensil itself is similarly used and held
The structure of plug type joint is not herein to repeating).
The wavy metal pipe fitting cooperation of existing list mouth gas valve and existing gas-cooker is fixed using Green's crossover sub,
The cooperation of the wavy metal pipe joint screw thread of Green's crossover sub and gas-cooker, the spigot-and-socket joint of single mouth gas valve successively protrude into spiral shell
In the wavy metal pipe fitting of female, sealing ring and gas-cooker；But the spigot-and-socket joint of single mouth gas valve and the metal wave of gas-cooker
Being connected and fixed between line pipe fitting is fixed merely by the extruding of sealing ring, in daily life, the frequent shifting of gas utensil
The metal of visibly moved spigot-and-socket joint (or connector of the spigot-and-socket of gas utensil itself) and gas-cooker for easily causing single mouth gas valve
Loosening between corrugated pipe connector causes safety accident.
Summary of the invention
Technical problem to be solved by the invention is to provide it is a kind of it is structurally reasonable, be not easy the combustion gas Green loosened conversion and connect
Head.
In order to solve the above technical problems, the present invention provides a kind of combustion gas Green crossover subs；
Including attaching nut, sealing ring and at least one caging bolt, attaching nut's inner wall is provided with and gas utensil metal wave
The screw thread of line pipe fitting cooperation, attaching nut are provided at least one limit threaded hole, limit on the side wall of spigot-and-socket joint side
Position bolt cooperates with corresponding limit threaded hole, and caging bolt end is protruded into the inner hole of attaching nut and is resisted against spigot-and-socket and connects
On the side wall of head, sealing ring is sleeved in attaching nut, and ring inner hole agrees with spigot-and-socket joint outer wall.
With such a structure, sealing ring is first sleeved in attaching nut, and the connector of gas utensil metal bellows is from even
It protrudes into the inner hole of attaching nut on the right side of connected nut and is threadedly engaged between attaching nut, spigot-and-socket joint is on the left of attaching nut
The inner hole of attaching nut is protruded into, spigot-and-socket joint protrudes into the connector of gas utensil metal bellows through sealing ring, and sealing ring is protected
The sealing between spigot-and-socket joint and the connector of bellows is held, caging bolt protrudes into the inner hole of stop collar, and caging bolt supports
It leans against on the side wall of spigot-and-socket joint, the convex ribs cooperation of caging bolt and spigot-and-socket joint, limited connection nut connects with spigot-and-socket
Axial position between head.
Advantageous effects of the invention are as follows: it is structurally reasonable, be completely embedded, it is squeezed compared to the prior art using sealing ring
Fixed, the application limits the relative position of spigot-and-socket joint and gas utensil metal bellows using the structure of mechanical position limitation, in length
After time use, connection will not loosen between spigot-and-socket joint and gas utensil metal bellows, promote safety, and it is hidden to prevent safety
Suffer from, significantly solves pain spot of the existing technology.
The attaching nut of this combustion gas Green's crossover sub extends restraining position ring block to close to spigot-and-socket joint side, stop collar
Internal diameter is greater than spigot-and-socket joint outer diameter, and the internal diameter of stop collar is less than the connector outer diameter of gas utensil metal bellows；Using such
After structure, stop collar can limit the position of sealing ring, make sealing ring will not be from attaching nut close to spigot-and-socket joint side
Port skids off.
Several limit threaded holes, the limit are provided on the limit ring-side wall of the attaching nut of this combustion gas Green's crossover sub
Threaded hole and the caging bolt are one-to-one relationship, and the caging bolt cooperates with corresponding limit threaded hole, several limits
Position threaded hole is distributed along the axis uniform circular of stop collar；With such a structure, setting for threaded hole and caging bolt is limited
It is more reasonable to count, and meets the technical requirements of this combustion gas Green's crossover sub.
