速度制御弁である。2. Description of the Related Art As a speed control valve, it has already been shown in FIGS.
Is disclosed (Japanese Patent Laid-Open No. 2-174816). For example, when this control valve is provided in the air circuit to the cylinder S as shown in FIG. 5, the extension speed of the output shaft of the cylinder S is controlled. You can do it. In FIG. 5, symbol D is an electromagnetic valve, symbol A is an air source, symbol T is a tube, and symbol SC is a speed control valve.

排気専用流路９２Ｂとしている。As shown in FIG. 6 and FIG. 7, the speed control valve SC has a flow rate control valve in which a needle valve 90 is inserted into a tubular member 91 supported and fixed inside the joint body 9. The hole portion of the tubular member 91 is used as an air flow passage 92A, and the space between the inner wall of the joint main body 9 and the outer wall of the tubular member 91 is used as an exhaust flow passage 92B.

って排気専用流路９２Ｂが開いた状態となる。For example, as shown in FIGS. 6 and 7, a cone-shaped elastic diaphragm 93 is disposed in the exhaust passage 92B, and this elastic diaphragm 93 functions as an exhaust-dedicated valve. . That is, when the air is pumped from the air source A to the cylinder S, the air pressure causes the elastic diaphragm 93 as shown in FIG. 6 to be opened and the exhaust passage 92B to be closed. As the air is discharged, the elastic diaphragm 93 as shown in FIG. 7 is narrowed by the pressure of the air, and the exhaust passage 92B is opened.

Ｓ内の空気はチューブＴを介して電磁弁Ｄから短時間で

早戻りすることになる。Therefore, the amount of air per unit time at the time of discharging becomes larger than that at the time of supplying, and when the solenoid valve D is switched from the state of FIG. 5, the air in the cylinder S is electromagnetically transferred via the tube T. It is discharged from the valve D in a short time, and the output shaft of the cylinder S is quickly returned by the restoring force of the spring B.
【０００６】ところが、シリンダＳから電磁弁Ｄまでの
距離が長い場合、即ち、チューブＴを長くしなければな
らない場合、排気効率が非常に悪くなり、シリンダＳの
出力軸は早戻りしない。However, when the distance from the cylinder S to the solenoid valve D is long, that is, when the tube T has to be lengthened, the exhaust efficiency becomes very poor and the output shaft of the cylinder S does not return rapidly.

くない。As a means for solving the above problem, there is a method of interposing a rapid exhaust valve between the so-called flow control valve SC and the tube, but the rapid exhaust valve is extremely bulky as compared with the speed control valve. And since it is expensive, I do not want to use it as much as possible.

And a flow path switching valve 7 is provided at a branch portion of the fluid path 5 and the discharge-only path 6, and the flow path switching valve 7 is configured such that the fluid flows from the fluid source side connection portion 2 to the fluid device side. When flowing in the direction of the connection part 3, the discharge-only path 6 is closed to connect the fluid path 5, and when the fluid flows from the fluid device side connection part 3 toward the fluid source side connection part 2, It is assumed that the valve body 70 is moved so that the fluid path 5 to the fluid source side connection portion is closed and the fluid path 5 from the fluid device side connection portion and the discharge dedicated path 6 are communicated with each other.
A flow rate control valve 8 is arranged in the fluid path 5 between the flow path switching valve 7 and the fluid device side connection portion 3.

体は流体機器に供給される。The present invention operates as follows. [What can be done at a low cost] Since the exhaust port 4, the flow path switching valve 7 and the discharge-only path 6 have a rapid exhaust (liquid) function, it is not necessary to use an existing expensive rapid exhaust (liquid) valve. [Making it compact] The discharge port 4, the flow path switching valve 7, and the discharge-only path 6 that function as a rapid exhaust (liquid) valve are provided in the same member as the flow control valve 8, that is, in the small block-shaped joint main body 1. Therefore, it is not necessary to use the existing bulky quick exhaust (liquid) valve. [Able to enable rapid exhaust] When a fluid flows from the fluid source side connection portion 2 toward the fluid device side connection portion 3,
The fluid passage 5 between the fluid source side connection portion 2 and the fluid device side connection portion 3 is in a communication state by the valve body 70 of the flow passage switching valve 7, and the discharge between the fluid passage 5 and the discharge port 4 is performed. Dedicated route 6
Is shut off. Therefore, the fluid from the fluid source is supplied to the fluid device.

When the fluid flows toward, the fluid passage 5 between the fluid source side connection portion 2 and the fluid device side connection portion 3 is interrupted by the valve body 70 of the flow passage switching valve 7, and the fluid passage 5 and the drainage path 5 are discharged. The discharge-only path 6 with the outlet 4 is in a communication state. Therefore, the fluid from the fluid device is discharged from the discharge port 4 via the discharge dedicated path 6.

排気が可能である。As described above, the flow path switching valve 7 is switched depending on the flow direction of the fluid, but in the present invention, the fluid is discharged in the conventional route of fluid equipment → tube → solenoid valve. It is not executed. That is, in the speed control valve of the present invention, the fluid discharged from the fluid device via the flow rate control valve 8 is directly discharged from the discharge port 4. Therefore, as described in the section of the related art, rapid exhaust is possible even when the distance from the fluid device to the solenoid valve is long.

を配設してあることを特徴とする速度制御弁。1. A small block-shaped joint main body (1) is provided with a fluid source side connection portion (2), a fluid device side connection portion (3) and a discharge port (4), and inside the joint main body (1). To
The fluid source side / fluid device side connecting portions (2) and (3) form a fluid path (5) communicating with each other, and the fluid path (5)
To form a discharge-only path (6) branching from the communication path with the discharge port (4), and a flow path switching valve (7) is provided at a branch portion of the fluid path (5) and the discharge-only path (6). In addition to being provided, the flow path switching valve (7) closes the discharge exclusive path (6) when the fluid flows from the fluid source side connecting part (2) to the fluid device side connecting part (3). As a result, when the fluid flows in the direction from the fluid device side connecting portion (3) to the fluid source side connecting portion (2), the fluid path (5) to the fluid source side connecting portion is formed. Is closed and the valve body (70) is moved so that the fluid path (5) from the fluid device side connection portion and the discharge exclusive path (6) communicate with each other, and the flow path switching valve (7) A flow control valve (8) in the fluid path (5) between the fluid device side connection (3).
A speed control valve characterized by being provided with.
