(54) QUICK UNIT ELEMENTS

one

The invention relates to mechanical engineering, in particular to quick-disconnecting joints of elements, and can be used where a quick disconnection of a line transferring a liquid medium of small volumes and speeds is necessary, for example, in the medical and formacological industry.

A quick-disconnect connection of elements is known, which contains two abutting semi-plugs interconnected with a ball lock, in one of the semi-plugs of which a sealing sleeve 1 is placed.

However, the indicated quick-coupling of the elements does not reduce the volume of the flow channel.

The purpose of the invention is to reduce the volume of the passage.

This goal is achieved by the fact that a needle with side channels and a threaded spring-loaded cork with a union are installed in the half-socket with a sealing sleeve, and a self-piercing self-piercing diaphragm is placed in the other half-socket.

The drawing shows a quick coupling of elements, a general view.

The quick-disconnect connection of the elements contains two half connectors I and 2, which are interconnected by means of a lock with balls 3.

5 In the case of the semi-connector 1 there is disposed a sealing sleeve 4 mounted for movement on a hollow needle 5 made with a side exit of the channel. The cork 6 is screwed into the housing of the half-connector 1

Q with nozzle 7 and a hollow needle 5. The side exit of the canal of the hollow needle 5 can be hermetically sealed with a sealing sleeve 4, made, for example, of fluoroplastic and installed in the bead 8 with the collar, having the ability to move freely

15 in the semi-plug 1 under the action of the spring 9 up to the stop of the bead of the cup into the body of the semi-plug 1. A sleeve 10 with a fitting is inserted into the body of the semi-plug 2, which is pressed against the inner end of the semi-plug case

2Q by a nut 11. The passage through the half-plug 2 is hermetically sealed by a self-engaging self-engaging diaphragm 12 made, for example, of latex. The handle 13 with the annular groove 14 has the ability to move along the half connector 1 by the action of the spring 15, the stop for which is the washer 16 held on the half connector 1 by the spring ring 17. The proposed quick-release capillary connection works as follows. In the open state of the quick disconnect connection of the elements, the handle 13 is in its extreme upper position. In this case, the spring 15 is compressed, and the balls are in the annular groove 14 and are locked in it by means of a cup 8, which, together with the sealing sleeve 4, is also in its extreme upper position under the action of the spring 9 and is held by the collar. The needles 5 are closed by a sealing sleeve 4. When the semi-plug 1 is connected to the semi-plug 2, the latter is inserted into the body of the half-plug 1. The front surface of the half-plug 2 presses on the cup 8, compressing the spring 9. At the same time, the needle 5 pierces the self-engaging diaphragm 12 and enters In the opening of the sleeve 10, and going downwards, the sealing sleeve 4, tightly pressed against the diaphragm 12, opens the side outlets of the needle channel 5, when they completely pass through the diaphragm 12. Semi-connector 2 moves to align the annular groove 18 with the balls 3, after which the handle the fabric 13 is pushed by the spring 15 to the lowest position and locks the balls 3 in the groove 18 of the semi-connector 2. To open the connection, it is necessary to raise the handle 13 to the upper position, then the balls 3 enter the annular groove 14. The spring 9 lifts up the hollow needle 5 up the sealing sleeve 4 with the cup 8, which locks the balls 3 in the annular groove 14, and pushes the semi-plug 2 out of the semi-plug 1. The proposed quick-release capillary connection allows you to quickly disconnect and connect any lines that transmit liquid or gas at low speeds, volumes and pressure. At the same time, the undocking and joining operations themselves are extremely simple, i.e., when undocking, you only need to pull the handle upwards; when connected, just slide one half connector into the other. This allows the proposed connection to be applied in special conditions where the operator is in special clothing and his movements are difficult. The purpose of the compound is to transfer the valuable biopreparation into the electrophoretic separation chamber, while the compound, due to its capillary section, has insignificant losses of valuable raw material, and the small dimensions of one semi-plug allow thermostatic control of the biological product connected to one half-plug in the refrigerator. In addition, leaktightness during re-joints excludes the loss of valuable raw materials inside and outside the joint, which is especially necessary in special conditions. Claims of the Invention A quick-release connection of elements comprising two abutting semi-plugs interconnected by means of a ball lock, in one of the semi-plugs of which a sealing sleeve is placed, wherein in order to reduce the volume of the flow channel, a needle is installed in the plug with a sealing sleeve with lateral channels and a threaded spring-loaded cork with a choke, and in the other semi-plug is a self-piercing self-locking diaphragm.
