Description

Technical Field

[0001] This utility model relates to steel cylinders, and more particularly to gas-liquid two-phase steel cylinders. Background Technology

[0002] Two-phase gas cylinders (also known as gas-liquid dual-phase cylinders) are mainly used to store liquefied petroleum gas in both gaseous and liquid states simultaneously, achieving the separation and conversion of the two phases through pressure vessel technology.

[0003] Gas cylinders generally need to be equipped with valves. The commonly used structure is to open a hole at the top of the cylinder, install a valve seat at the opening, and then install the valve on the valve seat. First, this structure requires opening a hole on the curved top surface of the cylinder, which will cause burrs and flanges around the opening, requiring further processing. Second, the fixation of this structure relies on welding. The high temperature generated during welding will damage the original metallographic structure and heat treatment state of the cylinder metal, causing the material strength and toughness of the weld heat-affected zone to drop sharply, becoming a weak point. Utility Model Content

[0004] This utility model addresses the problems in the prior art. The technical problem to be solved by this utility model is to provide a gas-liquid two-phase steel cylinder.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A gas-liquid two-phase cylinder includes a cylinder body and a gas-liquid two-phase valve. The top of the cylinder body is pulled up to form a concave part. The lower part of the concave part is a hollow cylindrical structure with a step at the bottom. The inner wall of the cylindrical structure is provided with internal threads and is threaded to an annular reinforcing plate that fits with the concave part. The edge of the reinforcing plate is welded and fixed to the concave part. The lower part of the reinforcing plate is provided with internal threads and the gas-liquid two-phase valve is threaded to this point.

[0006] Preferably, a first sealing ring is provided on the step, and the bottom end of the reinforcing piece abuts against the first sealing ring to form a seal.

[0007] Preferably, the gas-liquid two-phase valve is provided with an external thread and a second sealing ring is fitted on it. The lower part of the external thread is threadedly connected to the reinforcing plate, and the upper part of the external thread is threadedly connected to a pressure ring. The bottom end of the pressure ring presses the second sealing ring onto the reinforcing plate to form a seal.

[0008] Preferably, the pressure ring is a ring-shaped stepped structure with an outer wall beveled at the bottom to form a slope.

[0009] Preferably, the edge of the reinforcing sheet is provided with a notch to increase the length of the welding line.

[0010] Preferably, the gas-liquid two-phase valve has an exhaust channel and a liquid discharge channel inside, each channel is equipped with a screw-on valve core, and the inner end of the channel is connected to a siphon tube extending near the bottom of the bottle.

[0011] Compared with the prior art, the present invention has the following advantages: The present application forms a concave part by thickening and stretching the material of the top section, forming a through hole in the concave part, threading and welding a reinforcing plate in the concave part, and installing a valve on the mounting base. The reinforcing plate and the concave part form a multi-directional limiting and can be initially fixed, which not only facilitates subsequent welding, but also disperses the force to multiple positions when subjected to external force after welding, greatly improving the impact resistance.

Detailed Implementation

[0014] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0015] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0016] This embodiment mainly describes the title of the gas-liquid two-phase gas cylinder, as follows: like Figure 1-4As shown, a gas-liquid two-phase cylinder includes a cylinder body 10 and a gas-liquid two-phase valve 30. The top of the cylinder body 10 is pulled up to form a recess 101. The lower part of the recess 101 is a hollow cylindrical structure with a step 1011 at its bottom. The inner wall of the cylindrical structure is provided with internal threads and is threaded to an annular reinforcing plate 20 that fits with the recess 101. The edge of the reinforcing plate 20 is welded and fixed to the recess 101. The lower part of the reinforcing plate 20 is provided with internal threads and the gas-liquid two-phase valve 30 is threaded to this location. This solution involves thickening and stretching the material of the top section to form a recessed portion 101, creating a through hole in the recessed portion 101, threading and welding a reinforcing plate 20 into the recessed portion 101, and installing a gas-liquid two-phase valve 30 on the mounting base. The reinforcing plate 20 and the recessed portion 101 form multi-directional limiting and can be initially fixed, which not only facilitates subsequent welding but also disperses the force to multiple positions when subjected to external forces after welding, greatly improving the impact resistance.

[0017] Preferably, a first sealing ring 40 is provided on the step 1011, and the bottom end of the reinforcing piece 20 abuts against the first sealing ring 40 to form a seal.

[0018] Preferably, the gas-liquid two-phase valve 30 is provided with an external thread and a second sealing ring 60 is fitted on it. The lower part of the external thread is threadedly connected to the reinforcing plate 20, and the upper part of the external thread is threadedly connected to a pressure ring 50. The bottom end of the pressure ring 50 presses the second sealing ring 60 onto the reinforcing plate 20 to form a seal.

[0019] Preferably, the pressure ring 50 has an annular stepped structure with an outer wall beveled at its bottom to form a slope. This slope facilitates the deformation of the second sealing ring 60 towards the concave side 101 when tightened, thereby increasing the sealing area.

[0020] Preferably, the edge of the reinforcing piece 20 is provided with a notch 201 for increasing the length of the weld line. This design not only increases the weld line but also allows the notch 201 to be filled by welding, which helps to improve the stability of the weld.

[0021] Preferably, the gas-liquid two-phase valve 30 has an exhaust channel and a liquid discharge channel inside, each channel is equipped with a screw-on valve core, and the inner end of the channel is connected to a siphon tube 70 extending near the bottom of the bottle.
