UA53759C2 - Tightening element of a vessel - Google Patents

Abstract

A tightening element of a vessel relates to tightening elements of vessels filled with gas or liquid for long keeping. To provide overpressure of the vessel, double tightening of the mouth and control of the plug sealing, in the tightening element of the vessel including the mouth of the vessel with back valve closed with the plug tightened with respect to the mouth by means of a gasket installed in the mouth, and sleeve nut that is screwed on to the mouth, in the plug there are made long and radial openings, those connect the cavity of the mouth between the tightening ring and the gasket to the atmosphere of environment. At that, in the plug there are made two circular grooves in which there are installed tightening and stopping rings. At the threading of the sleeve nut there is installed a restrictor of its displacement in long direction, this is made as a screw.

Description

Description of the invention

The invention relates to the sealing of containers, and more precisely to the sealing devices of containers filled with 2 gas or liquid for long-term storage.

Well-known container sealing devices, for example; 1. "Tank connector" a. with. USSR Mo 283750, kl,

Е16К 17/19, which includes a non-return valve, a plug in the form of a glass, wound on the neck and interacting with teeth with a spring washer, 2. "Device for filling gas cylinders for cars", a. with.

Ukraine Mo 23090А, кл,бЕ17С5/00, which includes a refueling hose, a cut-off device, a throttle and a 70 separator. The devices of the first and second analogues ensure gas inflation of cylinders and close them with a non-return valve or a shut-off device. However, these devices do not provide reliable sealing of the filled container.

Of the known analogues of sealing devices, the closest to the proposed one in terms of technical essence is the fitting with a screwed plug with a gasket according to OST92-3966-76. .0С7Т92-3972-76, Such devices are used for sealing cylinders, containers in pneumohydraulic systems of products. 19 The main drawback of the described device is the insufficiently high degree of sealing of the container neck and the impossibility of objective control of the sealing of the plug in the neck.

The invention is based on the task of creating a compacted cavity in the neck and holes for the flow of the working fluid into the container, as well as longitudinal movement of the plug in the neck to ensure the pressure of the container, double sealing of the neck with a non-return valve and a conical gasket after filling the container with compressed gas and carrying out control of the sealing of the plug in neck

This task is solved due to the fact that in the proposed device the plug is made with a longitudinal hole, connecting through radial holes with the cavity of the neck sealed on one side by a gasket, and on the other by a sealing ring, and the longitudinal movement of the union nut is limited by a locking ring on one side and a limiting screw in the second with

To explain the design of the sealing device and its operation, a drawing is offered, Ge)

In fig. 1 shows the main view of the device in the initial position;

In fig. 2 shows the relative position of the parts when filling the container.

The proposed device consists of a valve 1 pressed by a spring to the seat A, a neck 2, a plug C with a longitudinal hole B and radial holes B, a conical gasket 4 arranged in a lock on the plugs C and neck 2, a sealing ring 5 installed in the annular groove of the plug With, a cap nut 6, a limiting screw 7 and a locking ring 8 installed in the annular groove of the plug.

At the same time, the continuation of the thread of the nut b to the screw 7 is larger than the length of the insertion of the plug Z y - a lock, with a neck 2. со

The proposed device works as follows; 3o - In the initial position, the valve 1 is pressed by a spring to the seat A: a gasket 4 is installed in the socket of the neck 2; plug C with a sealing ring 5 and a nut 6 with a locking ring 8 placed on it is installed in the neck 2; a nut 6 is screwed onto the thread of the neck 2 without tightening, into the thread of which the limiting screw 7 is screwed. "- To fill the capacity, the nut 6 is twisted from the neck 2 and resting with its end on the retaining ring 8, pulls the plug C with it to the stop of the screw 7 in the end Г of the neck . Compressed gas is supplied to the device in the direction of arrow D through holes B and B and the cavity of the neck to the end of valve 1. Ring 5 seals the working cavity

From" neck 2 from the surrounding atmosphere. - Under the pressure of the working gas on the end of the valve 1, the latter moves away from the seat. A and the tank begins to be inflated with gas to the set pressure, - After the inflation is finished, the gas pressure in front of and behind the valve is equalized and the valve 1 is pressed against the seat A by the force of the spring i-th, blocking the gas outlet from the tank 5 nut (Z is screwed onto the neck, while the gasket 4 is tightened with the force that ensures the tightness of the separate connection, which performs the second threshold of sealing the neck of the container. 7 - Sealing control of the plug With the gasket 4, it is carried out according to the drop in the pressure of the gas supplied to the plug sl 20 3 in the direction of the arrow D.

Thus, the design of the proposed device provides double sealing of the neck and objective control of sealing, which increases the reliability of the device and the sealing of the container, as well as reduces material costs.

In addition, the technology of operating the product has been simplified, as it is not necessary to carry out such operations as removing 25 plug 3, installing and removing an additional device, and re-installing the plug.
