Description

Gas outlet connection device

This creation relates to a gas outlet or gas terminal, and more particularly to a gas outlet connection for a medical gas supply system.

Press, Medical Gas Outlet (Gas Terminal) is a medical device used to obtain various gases (such as oxygen, nitrogen, nitrous oxide, vacuum, etc.) from medical gas supply systems. The device can be understood as a connector of a gas pipeline. The plug of a gas device (such as an oxygen inhalation bottle or an oxygen flow meter) can be directly inserted into the medical gas outlet to take gas. Chinese Patent No. CN203797200 No. discloses a "improved medical gas terminal", which is shown in the first figure, which comprises a mounting seat 10, a bottom ring 11 and a plug body 12, and a spool 13 is arranged in the bottom ring 11, the valve core 13 A first spring 14 is disposed between the bottom portion of the bottom ring 11 and the bottom portion of the bottom portion of the bottom portion 11 has a hollow structure, and a bottom annular plate 121 extending outwardly from the bottom periphery of the plug portion body 12, the bottom ring 11 A second annular pressure plate 111 is disposed on the outer wall of the first annular platen 121. The inner wall of the insertion portion body 12 is provided with two sliding slots 122. The sliding slot 122 is laterally disposed with a positioning tip 123. The outer wall of the plug body 12 is sleeved with a sheath 15 and the sheath 15 is sheathed. There is a gland 16, and a second spring 17 is disposed between the sheath 15 and the first annular pressure plate 121. The working principle is as follows: after the plug of the gas device is inserted into the plug body 12, the convex portion of the plug will be positioned. The tip 123 is squeezed out, and when the head of the plug is docked with the spool 13, the positioning tip 123 is reset, and the boss of the plug is caught. The valve core 13 is pressed by the head of the plug, and the air passage is opened. When the plug needs to be taken out, the sheath 15 is moved downward by pressing the pressure cover 16 downward, and the positioning tip 123 slides into the sliding slot 122. At the same time, the first spring 14 drives the valve core 13 to move up and reset, and the air circuit is closed. When the pressure cover 16 is released, the sheath 15 drives the pressure cover 16 to move up and reset by the action of the second spring 17.

Although the conventional gas terminal can realize the quick insertion of the gas device plug through the pressing method, it only has a single valve member structure (ie, the valve core 13), and can be switched and controlled without the need to insert the gas device. In the state of the valve structure design, since the gas supply lines of the various gas terminals in the hospital are usually used in series, if the conventional gas terminal fails or is damaged, the entire gas supply system must be shut down to be repaired or replaced, which will affect other normal conditions. The operation of the gas terminal greatly reduces the practicability and maintenance convenience of the product; in addition, the installation and use of the gas equipment usually have angle or direction restrictions. For example, the oxygen flow meter must be perpendicular to the floor to be normal. The ground flow is displayed. For this, please continue to refer to the first figure. Generally, the positioning hole 124 is disposed on the plug body 12 of the gas terminal, and the corresponding positioning protrusion is also provided on the gas device. Used to achieve the foolproof when docking, because in the hospital, the gas terminal is usually installed with a gas terminal box embedded in the wall body, The gas terminal is installed in the gas terminal box. In practice, the gas terminal often needs to change and adjust the installation angle according to factors such as the length and width dimensions of the gas terminal box, the construction or installation space, and the wiring direction of the gas supply pipeline (for example, going forward) The clock direction is rotated by 90 degrees, where the rotation is performed under the direction in which the insertion hole of the plug body 12 is held toward the constructor, but this also changes the angular orientation of the positioning recess 124 at the same time, resulting in Gas equipment cannot be installed at the right angle, which causes great trouble to the construction. Therefore, how to improve the above-mentioned defects is the technical difficulty that the creators of this case want to solve.

In view of the existing gas terminal, it does not have a gas circuit switching valve structure that can be used for maintenance, and it is also impossible to adjust the installation angle according to actual needs without affecting the gas equipment, resulting in the convenience of product maintenance and construction. Both are poor, so the purpose of this creation is to develop a gas outlet connection with a service valve that can be changed according to the user's needs.

Another object of the creation is to develop a gas outlet connection that reduces the leakage of the service valve and increases its service life.

In order to achieve the above objective, the present invention provides a gas outlet connecting device, comprising: a valve seat, the valve seat is provided with a socket joint portion, and the socket joint portion is provided with a plurality of socket joint holes, and the valve seat is provided with a repair a valve spool mechanism, the valve core mechanism and the valve seat are combined with each other; a needle valve assembly, the needle valve assembly and the valve seat of the maintenance bolt slot are combined; a plug mechanism, the valve seat The plug mechanism has a plug portion body, and the plug portion body is provided with at least one mounting hole that cooperates with the socket coupling hole, and the number of the socket coupling holes is greater than the number of the mounting holes.

With the above structure, the present invention can switch the gas path state without inserting the gas equipment amount, and can realize the purpose of convenient and rapid maintenance. At the same time, the creation can change the installation angle of the valve seat according to the user's needs or the installation environment, and further It can greatly improve the applicability of the product and the convenience of installation and maintenance.
