Abstract
The utility model discloses a kind of steel cylinder and valve fixed structure, the steel cylinder includes bottle, valve is fixed on bottle, the valve includes valve fixed part, and formed with external thread structure in the valve fixed part peripheral outer wall, the bottle is formed through the fixing hole that runs through inside and outside bottle, and the fixing hole inwall that runs through is formed with the female thread structure being engaged with the external thread structure.The utility model female runs through fixing hole by directly being formed on bottle, direct progress valve and bottle are screwed, being welded and fixed for valve seat and bottle need not be carried out, there is no weld seam at the valve of steel cylinder, avoid the possibility that gas leaks at cylinder valve, to improve steel cylinder security so that steel cylinder of the present utility model can be filled with gases at high pressure, to increase the volume of steel cylinder；It need not weld simultaneously, and not need valve seat this parts, the installation of the utility model steel cylinder and valve fixes that more convenient, cost is lower.
Description
Technical field
It the utility model is related to a kind of fixed structure of gas cylinder parts, and in particular to the fixed structure of steel cylinder and valve.
Background technology
Valve is both provided with existing steel cylinder, by the welding seat on steel cylinder, then carries out the fixation of valve seat and valve
To realize the installation of valve, steel cylinder has weld seam with valve base chamber, and the installation of valve is cumbersome, and the presence of weld seam has steel cylinder
There is the risk that gas leaks.
The content of the invention
It is more convenient that the purpose of this utility model is to provide a kind of fixation of valve and steel cylinder, and can improve steel cylinder safety
Property, avoid gas leaks in steel cylinder steel cylinder and valve fixed structure.
To achieve the above object, the utility model adopts the following technical scheme that：A kind of steel cylinder and valve fixed structure, it is described
Steel cylinder includes bottle, and valve is fixed on bottle, and the valve includes valve fixed part, and the valve fixed part peripheral outer wall
On formed with external thread structure, the bottle is formed through the fixing hole that runs through inside and outside bottle, described to run through fixing hole inwall
Formed with the female thread structure being engaged with the external thread structure.
The utility model by directly formed on bottle it is female run through fixing hole, directly carry out valve and bottle
Be screwed, it is not necessary to carry out being welded and fixed for valve seat and bottle, there is no weld seam at the valve of steel cylinder, avoid at cylinder valve
The possibility of gas leakage, to improve steel cylinder security so that steel cylinder of the present utility model can be filled with gases at high pressure, to increase steel cylinder
Volume；It need not weld simultaneously, and not need this parts of valve seat, the installation of the utility model steel cylinder and valve is fixed more
For convenience, cost is lower.
Preferably, the valve is formed with the valve positive stop lug boss extended laterally, when the valve and the bottle
It is screwed, the valve positive stop lug boss is located on the outside of the bottle, and the end face of the valve positive stop lug boss and the bottle
Outer surface offsets.The fixation of valve is easy in above-mentioned setting.
Preferably, the face that the valve positive stop lug boss contacts with each other with the bottle is plane.Above-mentioned setting is easy to
The fixation of valve, and make the processing of the utility model bottle and valve more simple.
Preferably, the bottle has been internally formed fixed lobe, it is described to run through the fixed lobe through fixing hole.It is logical
Cross and fixed lobe is set to increase the length through fixing hole internal thread, so that the fixation of valve and steel cylinder is more firm, to protect
Demonstrate,prove the security of the utility model steel cylinder.
Preferably, the fixed lobe is integrally formed with the bottle.Fixed lobe is not single part, it is not necessary to
The raised fixation with steel cylinder is fixed.Wherein fixed lobe can be formed in several ways, such as star drill is big so that steel
Bottle body material enters on the inside of steel cylinder to form the fixed lobe, just convex integrally formed with fixation when also can be by casting steel cylinder
Rise.
The utility model steel cylinder does not have weld seam with valve bearing, has steel cylinder security higher, can be filled with gases at high pressure
To improve steel cylinder capacity, reduce the advantages of steel cylinder volume；And the utility model steel cylinder and technique needed for valve fixation are simpler, solid
It is lower to determine cost.
Brief description of the drawings
Fig. 1 is a kind of structural representation that the utility model steel cylinder is fixed with valve；
Fig. 2 is a kind of structural representation of the utility model steel cylinder.
Embodiment
The utility model is further described below according to the drawings and specific embodiments.
As shown in Fig. 1, Fig. 2, steel cylinder of the present utility model and valve fixed structure, steel cylinder include bottle 1, and valve 2 is fixed
On bottle 1, valve 2 includes valve fixed part 21, and formed with external thread structure, bottle in the peripheral outer wall of valve fixed part 21
1 be formed through running through fixing hole 11 inside and outside bottle, through the inwall of fixing hole 11 formed with being engaged with external thread structure
Female thread structure.Integrally formed with fixed lobe 13 inside bottle 1, run through fixed lobe 13 through fixing hole 11.
Valve 2 is formed with the valve positive stop lug boss 22 extended laterally, and when valve 2 and bottle 1 are screwed, valve is spacing
Boss 22 is located at the outside of bottle 1, and the end face of valve positive stop lug boss 22 offsets with the outer surface of bottle 1, valve positive stop lug boss 22 and
The face that bottle 1 contacts with each other is plane.
The utility model steel cylinder does not have weld seam with valve bearing, has steel cylinder security higher, can be filled with gases at high pressure
To improve steel cylinder capacity, reduce the advantages of steel cylinder volume；And the utility model steel cylinder and technique needed for valve fixation are simpler, solid
It is lower to determine cost.
