The claimed design of the protective cap of the valve of the gas cylinder is made in the form of a single structure, which mainly contains a cylindrical rim connected to the cylindrical neck, providing space for access to the valve, the rim and neck made of pipe segments, the neck contains an internal thread for installation on the cylinder body, and in the upper part of the rim is made a receiving hole for transporting the cylinder.

Description

FIELD OF TECHNOLOGY

The claimed device relates to the sealing elements of cylinders with a fluid medium under pressure, in particular, to a protective cap for gas cylinders.

BACKGROUND

An analogue of this solution is the safety cap of a gas cylinder (patent RU 2617646, 04/25/2017), which contains a handle that forms a protected space, and the lower end of the handle is attached to the base, essentially of a ring-shaped shape, which is designed to be installed around the neck of a cylinder with a fluid under pressure, the arch contains a metal sheet formed by stamping, and the arch contains at least one rib that extends in the direction of arch bending along the entire length of the arch or in part, than said at least one rib is formed by stamping bending.

The main disadvantage of this device is that the part of the cap intended for installation on the cylinder is fixed by the principle of flange connection, in particular, using a locking element (for example, a bolt), which reduces the tightness of the locking device and reduces the safety of its use. At the same time, this principle of fixing the device on the cylinder allows it to be dismantled by removing the locking element, which also significantly reduces its protective function.

Also, the shape of the cap presented does not allow free access to control devices installed on the cylinder valve, for example, pressure gauges.

DISCLOSURE OF A USEFUL MODEL

The claimed device is aimed at eliminating the existing disadvantages of the analogue.

The technical result is to increase the tightness of the cap, through the use of the threaded principle of its fixation on the body of the cylinder.

Additionally, the convenience of access to the control devices installed on the cylinder is ensured due to the provision of free space by the cap body design, as well as the simplification of the movement of the cylinder with the cap installed due to the opening in the upper part of the cap.

The claimed design of the protective cap of the valve of the gas cylinder is made in the form of a single structure, which mainly contains a cylindrical rim connected to the cylindrical neck, providing space for access to the valve, the rim and neck made of pipe segments, the neck contains an internal thread for installation on the cylinder body, and in the upper part of the rim is made a receiving hole for transporting the cylinder.

In a private embodiment of the device, the rim is attached to the neck by welding.

In a private embodiment of the present device contains a coating of soil-enamel.

In a private embodiment of the device, the ratio of the diameter of the rim to the neck is 2: 1 ± 10%.

In a particular embodiment of the device, it comprises a layer of water glass on the neck thread.

In a private embodiment of the device, it is made of segments of seamless steel pipes without detachable joints for fastening to the container body.

In a particular embodiment of the device, the thread pitch is 2 3/4 ''.

DESCRIPTION OF DRAWINGS

In FIG. 1 presents a view of the claimed product.

IMPLEMENTATION OF A USEFUL MODEL

The claimed design of the protective cap (10) for the valve of the gas cylinder is a single structure made of two pipe segments. The cap (10) contains a predominantly cylindrical rim (1) connected to the cylindrical neck (2). The rim (1) and the neck (2) are made of seamless steel pipe segments without detachable joints. The diameter of the rim (1) is approximately 2 ± 10% times the diameter of the neck (2). The rim (1) and the neck (2) are rigidly fixed to form a single part, for example, by welding.

The rim (1) provides space for easy access to the valve of the cylinder, which also allows the use of various types of control devices for the valve, for example, various variations of pressure gauges.

An internal thread (3) is made on the neck (2), for example, in increments of 2 3/4 '', to ensure that the cap (10) is screwed onto the neck of the cylinder. An opening (4) is made in the upper part of the rim (1) for transporting the cylinder. The hole (4) is used to transport the cylinder with the installed cap (10) using standard improvised tools, for example, a screwdriver, which allows you to use it as a handle when rolling the cylinder.

Additionally, the cap (10) may be coated in the form of primer-enamel, as well as the name of the owner of the container or other information using shock-dot marking or otherwise.

Also, when installing the cap (10) on the cylinder, an additional layer of liquid glass can be applied to the thread (3) of the neck (2), which provides additional tightness and greatly complicates the procedure for removing the cap (10) from the cylinder.

Claims (4)

1. The protective cap of the valve of the gas cylinder, made in the form of a single structure, containing mainly a cylindrical rim connected to a cylindrical neck, providing space for access to the valve, the rim and neck made of pipe segments connected by welding, with the ratio of the diameter of the rim to the neck is 2: 1 ± 10%, while the neck contains an internal thread coated with a layer of liquid glass for fixing on the body of the cylinder, and in the upper part of the rim made a hole for transporting the container with the help of available tools. 2. The cap according to claim 1, characterized in that it contains a coating of soil-enamel. 3. The cap according to claim 1, characterized in that it is made from segments of seamless steel pipes without detachable joints for fastening to the container body. 4. The cap according to claim 1, characterized in that the thread pitch is 2 3/4 ".
