UA143886U - Sealing shield for protecting gas meters - Google Patents

Abstract

The invention relates to the industrial use of a sealing shield on gas meters, which can be used: in the private sector by installation companies in order to improve and ensure the protection of gas meters, and also more broadly in the context of public services for the installation of sealing shields on existing or newly installed meters. The invention consists of a sealing shield and locking elements in the form of semi-circular catches with a locking system, which completely enclose and protect a gas meter, locking the joint by sealing, and protecting against external unauthorized intervention. As a result of the design of the invention consisting of two separate component parts, the sealing shield can be mounted independently of the meter without the need to dismantle the latter, since the sealing shield is mounted directly on the meter, thereby protecting both the point of entry of the gas pipes (flanges) and existing seals.

The utility model belongs to the industrial application of the shell-seal on metrological gas meters with the possibility of use both in the field of private use of the object by installation companies for the improvement and protection of gas meters, and for wide application within the framework of public services for the installation of the shell-seal on existing or newly installed meters.

Analogues are protective metal boxes, a monolith, combined with the cavity of the installed gas meter. Disadvantages of analogues are the need to disassemble the counter to install a protective box, as well as the lack of protection against unauthorized access.

Also known is a device for protecting the meter, which, as in the previous case, is a box combined with the internal cavity of the installed gas meter, which, in addition, has a door with a safety lock, which allows elementary access, excluding a high level of security , protect the meter from unauthorized access.

The disadvantage of the existing device is the need to disassemble and dismantle the meter from the gas networks to install the protective box, as well as the low level of security against unauthorized access, which is provided by a lock with a key.

A device in the form of a cover is known, which covers the front part of the meter with side clamps for fixation on the meter. The lid is made of polystyrene.

The presented cover is made with the possibility of simplified assembly or disassembly.

The device does not completely eliminate the shortcomings of previous analogues, but it allows you to fix the cover without dismantling and disconnecting the meter from gas sources.

Regarding the analogues presented, it should be noted that none of them provides for and does not reveal the characteristics of the seals regarding the entry of the wires into the meter, as well as the protection of the existing seals of the meter, and last but not least - the mechanical protection of the meter from electromagnetic factors that negatively affect functionality device

The task of a useful model is the possibility and convenience of installing a shell-seal for the protection and safety of the gas meter from physical external and human factors. The utility model is strictly necessary for public services that need to install or replace an unlimited number of gas meters in a short period of time and with high security requirements.

A useful model also has a high priority for the economic and energy security of the state,

Because it will allow to eliminate problems of access for the purpose of theft, change of data and will ensure environmental safety from unauthorized access.

The task is solved as follows: 1. The shell seal is installed on old or new meters, maintenance and/or repair is provided without removing the gas meter from the centralized network. 2. Sealing of pipe joints (flanges) at the entrance is provided using half-ring latches with a locking system, identification with an individual number is available, as well as numerical identification of the shell-seal body. 3. Protection of the existing meter seals is ensured by blocking against disassembly according to the technical parameters of the plant, as well as protection of the mechanical part of the meter from external influences.

A useful model belongs to the field of sealing and is a shell-seal covering the front of the meter, as shown in fig. 1 and 2. According to the useful model, the above disadvantages of analogues are eliminated. A useful model is a shell-seal, according to fig. 1 and 2, with clip-on elements that are presented as half-ring latches with a locking system according to fig. C and 4. The shell-seal completely covers and protects the gas meter, both its front part and the central part, which unites the upper and lower parts of the meter.

Half-ring valves with a locking system are connected to the body of the shell-seal and simultaneously protect the connection points (flanges) of gas pipes with the meter. The shell material is a seal according to fig. 1 and 2 and half-ring latches with a locking system according to fig. C and 4 are high-strength plastics, but are not limited to this material.

Two half-ring latches with a locking system, as shown in fig. 2 and 3, each have one locking element with a shell-seal body, creating an inseparable connection when closing. In the body of the shell-seal according to fig. C and 4 are recessed holes (or sockets) into which the half-ring latch elements with a locking system should enter, formed as two lateral depressions in the shape of a triangle (herringbone). Thus, recessed holes in the form of protrusions in the shell-seal are connected to depressions in the form of a triangle (herringbone) of the half-ring latch according to fig. 4.

To prevent the opening of the shell-seal, a locking mechanism is provided at the end of the connection. Interlocking is effected by the side depressions of half-ring latches with a locking system, which project beyond wall protrusions recessed into the body of the shell-seal, thereby allowing entry and exit locking.

Thus, there are protrusions in the recesses of the shell-seal, behind which the half-ring latch should enter and close when entering the depression. In the body of the shell-seal there is a depression with protrusions, two for each connection of the meter and gas pipes (flanges). For each of the half-ring latches with a locking system, there are 2 depressions, locking elements that interact with the corresponding protrusions of the shell-seal body.

The technical result is achieved by the fact that the shell-seal has two parts: directly the shell according to fig. 1 and 2 and half-ring latches with a locking system, according to fig. C and 4, which hermetically and safely close the gas meter from the inside. The body of the shell-seal according to fig. 1 and 2 is connected to two half-ring latches with a locking system according to fig. C and 4 with the help of two hollows of a triangular shape (herringbone) of a half-ring latch, which simultaneously protect the connection points (flanges) of gas pipes with the meter.

The strength of the shell-seal is provided by its hard impact-resistant plastic body, but its performance is not limited to this material, it is possible to use other materials with a hard and durable structure.

The safety of closing and protection of the shell-seal is ensured by half-ring latches with a locking system according to fig. 2 and 3, which interact inseparably with the body of the shell-seal.

Due to the fact that in the body of the shell-seal according to fig. 4, recessed holes or sockets are made, behind which triangular depressions (herringbone) of half-ring latches with a locking system enter, and the recesses or sockets of the body have protrusions, behind which fall depressions, half-ring latches with a locking system as in fig. 4 when closed are connected to each other and make the connection inseparable. 1. The possibility of implementing a useful model is explained by: 1) the industrial production of the shell-seal body, as shown in Fig. 1 and 2, the design is an external panel with an opening in the form of a window, which allows access to meter data; 2) manufacturing half-ring latches with a locking system with two triangular depressions (herringbone);

From 3) a technical installation in which the device interacts between its elements and works as a shell-seal for a gas meter, for this the meter is installed on the surface of the case according to fig. 1 and 2; this process does not require special technical assistance, does not require dismantling; the gas meter remains fully accessible and can be used by consumers or employees of service companies that collect data from natural gas consumers; 4) the next step of sealing is the connection of each of the half-ring latches with the locking system (Fig. 3 and 4) of the shell-seal body; 5) the body of the shell-seal according to fig. 1 and 2 is connected to two half-ring latches with a locking system according to fig. C and 4 with the help of two blocking elements, the depressions of which interact with the depressions of the shell-seal body, the depressions of the latch-half-ring go behind the protrusions in the depressions of the shell and are locked.

The useful model is designed for sealing and protection, this is achieved with the help of the mechanical part and the interaction between the elements of the shell-seal. Due to the fact that on the body of the shell-seal according to fig. 4 there are depressions or nests with protrusions, behind which go the hollows of a triangular shape (herringbone) latch-semi-ring, the end connection forms a system lock.

A useful model is explained by drawings: fig. 1 - an image of the front part of the shell-seal of fig. 2 - an image of the rear part of the shell-seal of fig. C - image of half-ring latches with locking system - internal drawing. fig. 4 - image of half-ring latches with locking system, top view.
