Description

[Detailed description of the invention] This invention is installed on the wall of a room in a hospital, etc., and connected to a central control room through piping to safely supply oxygen, laughing gas, etc. to patients in each room over a long period of time. In such a wall system, the self-closing outleft valve mounting is related to the seat.

The concrete configuration of the above-mentioned wall system is as shown in FIG. 1, in which an outlet box a is mounted on the wall of each room or embedded in the wall, and an outlet valve b is installed inside each outlet box a. To install the seat C,
It is connected to a supply source d (oxygen cylinder, etc.) placed in the central control room through a supply pipe e, and the outlet valve b is generally installed on the seat in order to facilitate its replacement and inspection. The seat C is removably attached to the seat C by screw fitting, etc., but in the conventional installation, the seat C is attached to the second
As shown in the figure, the mounting is carried out on the seat body C', and the valve chamber f and the recess g are arranged vertically in parallel with each other communicating with each other through a passage, and the closing body i is screwed into the valve chamber f. It is supported by a cap nut j, and the above installation is done by inserting a screw g' into the recess g on the inner circumference and screwing the outlet valve b in a removable manner. It is made to protrude from a hole (not shown) in the lid of the left box a, and a knob l having a diameter larger than that of the hole is attached to the protruding end.

Therefore, when removing the outlet valve b to replace the backing, etc., first remove the knob l, then remove the lid k of the outleft box a, and then screw the closing body i with a screwdriver etc. The hole m is closed to prevent the outflow of oxygen, etc., and then the outlet valve b is removed from the recess g for installation.

However, as mentioned above, outlet valves B are installed in large numbers in hospitals, and maintenance such as replacing the backing is quite frequent, which is very troublesome and requires a lot of effort and time. Ta.

Therefore, the present invention was developed in consideration of the above-mentioned conventional circumstances, and by appropriately arranging a self-closing movable valve at the seat instead of the conventional closing body, the outlet valve can be installed automatically by simply attaching and detaching the outlet valve. The purpose is to make it possible to supply and cut off oxygen, etc. to the

The drawings showing the embodiments of the present invention will be described in detail below.
In Figures 3 and 4 showing the installed state of the outlet valve b, the seat body 1 is horizontally long and has a thickness that can be installed in the outlet box 2, and a valve hole 4 is provided in the center. A valve seat 3 that is integral with the main body 1 defines a valve chamber 5 and a valve mounting space inside the valve chamber 5 with recesses 6 oriented at right angles to each other and each other end being open.

At the open end of the valve seat 5, a spring receiver 9 which airtightly connects the supply pipe 7 to the supply port 8 is airtightly fitted and supported by a cap nut 10 screwed onto the main body 1. The valve chamber 5
It is available to supply.

Further, the valve chamber 5 includes a valve portion 11a and a valve rod 11b.
A movable valve 11 having a substantially T-shaped side surface is installed with its valve rod 11b inserted into the recess 6 from the valve hole 4, and is installed with one end supported by the spring receiver 9. The auxiliary spring 12 elastically biases the valve portion 11a in the direction of seating the valve seat 3, and thus the movable valve 11
is internally movable in the axial direction.

In addition, a backing 13 is attached to either the valve portion 11a of the movable valve 11 or the facing surface of the valve seat 3 to make the seat airtight, and the backing 13 is attached to the valve rod 11b and the backing 13 is attached to the valve rod 11b. The valve holes 4 to be inserted are each formed with an appropriate diameter so as to maintain an appropriate distance between them and form a passage for oxygen, etc., and the valve rod 11b is a recessed portion for mounting the valve. 6
It protrudes long to approximately the center line of the outlet valve B, and is capable of interfering with the attached outlet valve b.

In addition, for the above-mentioned valve installation, the open end of the recess 6 is a threaded hole 6a, into which the outlet valve b is threadedly fitted.
The hollow spring spring holder 16, which is pressed by the spring 15 which elastically biases the closing valve 14, extends outward for a long time and interferes in pressing the valve rod 11b of the movable valve 11 in the axial direction as described above. It is possible.

In the movable valve 11 illustrated in FIG. 3, the end of the valve rod 11b is interfered with the tapered part 16a provided at the end of the spring retainer 16 protruding from the threaded part 1' of the outlet valve b, so that the spring retainer 16 in a direction perpendicular to the spring 16 against the pressure of oxygen or the like and the elastic force of the auxiliary spring 12.

By forming the spring retainer 16 of the movable valve 11 and the outlet valve b in this manner, the opening and closing operations of the movable valve 11 can be performed smoothly in the axial direction.

Further, as shown in FIG. 4, the valve hole 4 of the valve seat 3 may be made larger in diameter than in the above-mentioned embodiment, and the movable valve 11 may be swingably supported by an auxiliary spring 12. If the movable valve 11 is formed in the outlet valve b, the valve opening operation can be performed simply by providing the spring retainer 16 of the outlet valve b flatly.

In the above-mentioned stealing, when oxygen, etc. (not shown) is supplied from the supply source to the valve chamber 5 through the supply pipe 7, the movable valve is moved by the pressure of the oxygen, etc. and the elastic force of the auxiliary spring 12. 11 is pressed in the direction of the valve seat 3, that is, in the right direction on the drawing paper, so when the outlet I and valve b are left alone, the valve portion 11a of the movable valve 11 is pressed against the valve seat 3 and closed. When the valve is installed, the supply of oxygen, etc. to the recess 6 is stopped.

In the above-mentioned closed state, when the outlet valve b is fitted into the recess 6, the taper part 16a of the spring retainer 16 or the tip of the valve rod 11 is attached.
Since b is interfered with, the movable valve 11 is pushed or swung into the valve chamber 5 against the pressure of supply gas such as oxygen and the elastic force of the auxiliary spring 12, and the valve part 11a is closed. Leave the seat 3 and open the valve.

Therefore, oxygen and the like are supplied to the outlet valve b through the valve hole 4, the valve mounting recess 6, and the hollow spring retainer 16.

Since the outlet valve b is equipped with a closing valve 14, it is opened by connecting a humidifier n as shown in FIG. Supplied.

As explained above, the mounting according to the present invention is based on the seat.The inside of the original body 1 is partitioned by the valve seat 3 provided in the middle of the internal longitudinal direction, and the valve chambers are located on both sides of the valve seat 3. 5 and a recess 6 for valve mounting are formed, and these valve chambers 5 and the recess 6 for valve mounting are formed with a valve hole 4 bored in the valve seat 3.
The opening end of the valve chamber 5 facing the valve seat 3 is closed via a spring receiver 9 to which a supply pipe 7 is connected. The opening end intersecting the seat 3 is a tapped hole 6a, and the movable valve 11 has a valve portion 11a and a valve rod 11b connected in a substantially T-shaped side surface.The valve portion 11a is a valve chamber. 5
The valve rod 11b is located inside the valve hole 4.
An elastic force is applied to the movable valve 11 in the direction of closing the valve hole 11a through an auxiliary spring 12 inserted therein and interposed between the valve portion 11a and the spring receiver 9. A threaded portion b' corresponding to the threaded hole 6a is formed at the end of the rear valve 1 to the let valve b, and a hollow spring retainer 16 is provided that protrudes from the threaded portion b'. The spring retainer 16 has a protruding length that abuts against the end of the valve rod 11b protruding into the recess 6 in the recess 6 when the valve is installed. Since outlet valve b is removably combined with the threaded portion b' and the threaded hole 6a, the valve is opened or closed by attaching and detaching the outlet valve b to the recess 6. Therefore, by simply removing the outlet valve b, oxygen, etc. can be automatically stopped, and work such as replacing or inspecting the outlet valve b itself or the backing can be easily performed.

In addition, the valve opening/closing direction of the movable valve 11 and the outlet valve b
Since the installation and removal directions cross each other, the dimension in the thickness direction can be reduced and it can be installed in a shallow outlet box 2. Therefore, the outlet box device can be mounted on a wall or embedded in the wall. This can be carried out conveniently without protruding forward from the wall surface etc. Furthermore, since the backing 13 is self-closing by the pressure of the supplied gas, the backing 13 will not be damaged, and therefore the outlet valve b can be It has practical effects such as being able to withstand frequent attachment and detachment and has excellent durability.

Furthermore, as described above, the valve opening/closing direction of the movable valve 11 and the attachment/detachment direction of the outlet valve b intersect, and when the hollow spring retainer 16 collides with the valve rod 11b, the end of the valve rod 11b Since the hollow end of the spring retainer 16 will not close, the valve will always function normally to open the valve without taking any special measures.Moreover, since the spring retainer 16 also serves as a valve opening tool, the overall The structure is simple and does not require any complexity or increased number of parts.
