The valve mechanism housed in the socket (10) is formed into an annular shape with a predetermined thickness in the radial direction, and includes a rubber packing (30) installed on the inner peripheral surface of the socket body (11>).
, press the rubber packing (30) to shut off the fluid;
The valve body (3
1) It is provided with a spring (32) placed behind the valve body (31) and biasing the valve body (31) in the valve closing direction. Then, the sleeve (15) is moved back to the rear of the ball (14) against the spring (16), the ball (14) is made swingable, and the plug body (21) is moved back to the socket body (11).
The sleeve (15) is returned to the forward position to lock the ball (14) in the annular fly (23) position, and the socket (10) and plug (20) are connected. As the plug main body (21) enters, the flat drive piece (33) connected to the valve body (31) at the rear end surface (17) of the plug main body (21) is moved rearward, and the spring ( 32), the valve body (31) is interlocked and retreated to open the valve, and the rear end surface (1
7) comes into contact with the rubber packing (30), and the socket (10
) (.Air is circulated from I+1 to the plug (20) side.Then, the sleeve (15) is similarly moved back, the ball (14) is made swingable, and the plug (20) for connecting the hose is moved.
) is pulled out and the valve body (31〉) is closed to block air flow. [Problems to be Solved by the Invention] In the socket (10) having the above configuration, the plug (20)
When the valve body (31) is released, the elastic force of the spring (32) presses the valve body (31) against the rubber packing (30) to shut off the fluid. However, when the valve body (31) is opened, as shown in FIG. 7, since the rubber packing (30) is an elastic body, the spring (32)
) is distorted by the elastic force, and is deformed by bending inward.
A slight gap is created between the outer circumferential surface (34) of the rubber packing (30) and the inner circumferential surface (13>) of the socket body (11) that comes into contact with it, and this gap allows the plug to be removed from the valve body (31) side. There is a risk of fluid leaking to the connection side.Therefore, in order to prevent such bending, in the wooden example, the rubber packing (30) is tightened with a large tightening force between the socket body (11> and the male screw member (12)). Therefore, conventionally, the socket body (11) is divided into two parts at the installation position of the rubber packing (30), and both parts are used to hold the rubber packing (30) with a large fastening force. It is necessary to support the valve body (31) and configure it so that the above-mentioned gap does not occur when the valve body (31) is closed. As a result,
This resulted in an increase in the number of parts and a complicated manufacturing process. In addition, since the rubber packing (30) is positioned and installed in this way, if there are variations in the dimensions of the socket body (11) and the plug (20), the ball (14) and the annular groove (23) If the positions do not match, you will not be able to smoothly attach and detach the plug (20), and in the worst case, the ball (14) will not fit into the annular groove (23).
The drawback was that it could not be locked. The purpose of this invention is to solve these problems by providing a valve mechanism that is housed in the socket of a novel one-touch fluid coupling, and which prevents fluid leakage when the valve body (31) is closed. The present invention provides a valve mechanism that eliminates the danger that occurs, reduces the manufacturing cost of the socket, and allows smooth operation of attaching and detaching the plug (20) despite variations in the dimensions of the members. [Means for Solving the Problem] In order to achieve this object, the present invention provides a valve mechanism that is housed in the socket of the one-touch fluid coupling, which comprises: An annular recess (4) is formed on the inner peripheral surface of the socket body (41).
3), and the rubber packing (50) is installed with a slight play with the outer circumferential surface (51) in contact with the recess (43), and the pressure contact surface of the valve body (31) with the rubber packing (50) is formed. (31a>, the inner peripheral surface (52) of the rubber packing (50)
The present invention provides a valve mechanism that is housed in a socket of a one-touch fluid coupling, characterized in that an annular convex striking surface (31b) is formed at a position along . Further, an annular recess (53) is formed in the inner circumferential surface (52) of the rubber packing (50), and a reinforcing ring (60) formed in an annular shape from an inelastic material is fitted into the recess (53). A packing (50) can be formed and a gap (53a) can be provided at the contact surface between the reinforcing ring (60) and the recess (53). Further, a plug contact surface (52a) is formed from the front end of the inner circumferential surface (52) of the rubber packing (50), and an annular protrusion (54) protruding inward is integrally formed on the plug contact surface (52a). Good too. Below, the structure, operation, and operation of the present invention will be explained with reference to the embodiments shown in the drawings.
The effects will be explained in detail. [Example] Figures 1 to 5 show examples of the present invention.
The valve mechanism of the present invention is housed inside the valve mechanism, and the same numbers as in the previous example in the figure indicate the same structure, so the explanation will be omitted. A male threaded portion (42) for piping connection is integrally formed in the rear half of the ringet body (41>),

A rubber packing (50) formed into an annular shape with a predetermined thickness in the radial direction is installed in the fourth part (43) with its outer peripheral surface (51) in contact with the rubber packing (50). Here, the width of the rubber packing (50) is set smaller than the full width of the recess (43) so that a minute gap (44) is created between the rubber packing (50) and the recess (43), and the rubber packing ( 50) is installed in the recess (43) with some play. In this example, the gap (44) is set to 0.5-. An annular recess (53) is formed in the inner circumferential surface (52) of the rubber packing (50), and a reinforcing ring (60) formed in an annular shape from an inelastic material such as metal or plastic is fitted into the recess (53). The reinforcing ring (60) has a generally wedge-shaped cross section and a recess (
53) is formed into a stepped shape with two steps in cross section, and a reinforcing ring (60
) and the recess (53). A gap (53a> is provided at the contact surface between the inner peripheral surface (52>) and the plug contact surface ( 5
2a> is formed, and an annular projection (54>) protruding inward is integrally formed at an arbitrary position of the plug contact surface (52a>.

[Operations] Next, the functions of this invention will be explained in detail with reference to embodiments. First, when the valve body (31) is closed after leaving the plug (20), the pressure contact surface (31a) of the valve body (31) is pressed against the rubber packing (50) due to the elastic force of the spring (32). The fluid is blocked.Here, the inner peripheral surface of the rubber packing (50)

The valve body to be housed in the socket of the one-touch fluid coupling of the present invention has its outer circumferential surface (51) in contact with the annular recess (43) formed in the inner circumferential surface of the socket body (41), and the rubber packing is inserted into the socket. (50) is installed with a slight play, so when the plug is connected, variations in dimensions of the socket body (11), plug (20), etc. are absorbed, and the ball (
14) to the circular ring (23) and then tighten the plug (2).
0) can be connected, and the plug (20) can be connected and removed smoothly. Furthermore, when the valve body (31) is closed after detaching from the plug (20), an annular convex step surface (
31b) prevents the rubber packing (50) from being distorted and deformed by bending inward, preventing a gap from forming between the outer circumferential surface (51> and the recess (43)), and preventing the The risk of leakage can be eliminated.In addition, the reinforcing ring (60) made of inelastic material can be inserted into the recess (53).
When the rubber packing (50) is fitted, the rubber packing (50) itself is reinforced to prevent unnecessary distortion, and a gap is created at the contact surface between the reinforcing ring (60) and the recess (53). (53a), when the valve body (31) is closed, the rubber packing (50
) distortion is absorbed, allowing stable operation. Therefore, the valve body (
31) Since it is expected that a gap will be created when closing,
There is no need to support the rubber packing (50) with two members with large fastening force as in the past, and the socket body (41
) is allowed to be made of Ikkyu material, and can be manufactured by simply installing the rubber packing (50) in the recess (42), reducing the number of parts, simplifying the manufacturing process,
It is possible to reduce manufacturing costs. Furthermore, by integrally forming an annular protrusion (54) on the plug contact surface (52a) formed from the front end of the inner circumferential surface (52), it is possible to completely seal the fluid when the plug is connected, and the plug In addition to eliminating fluid leakage during disconnection, this allows the fluid to be opened and closed in full synchronization with plug connection/disconnection, making it possible to use one-touch fluid couplings extremely safely.
