[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an automatic drain for automatically discharging drain generated during operation of an air source and a load machine.
Related to a discharge device .

[0002]

2. Description of the Related Art Automatic drain discharge means in this technical field is
Various types are already commercialized and already known. The prior art of these means will be described below by using a portable air source device which is an example of integrating the present technical field. Here, the following drain reservoir is normally used also as an air tank for storing load-utilized compressed air. The automatic drain drainage system has the following features: 1) a mechanical system in which a float is installed in the drain pool and the float reacts to a predetermined or higher water level to remove water; and 2) water is detected by electrically detecting the water level. Electric drainage system, and 3) a timed drainage system that automatically drains stagnant water that stays irregularly at regular intervals. The mechanical method of the above 1) is the simplest mechanism and is inexpensive, but easily breaks down due to fluctuations in the internal pressure.
Not easy due to internal opacity. In addition, since it is installed in a pressure-resistant container, repair in case of failure is not easy. In addition, the above-mentioned electric type, both the collective drainage method of 2) and the timed drainage method of 3), are both costly and have prevented their spread.

[0003] In the above-mentioned prior art, the drain is not operated in proportion to the amount of air used in the air circuit device or the amount of drain generated therefrom. that is,
The drain is grasped as a predetermined amount of stored water, the water level is detected, and as a result, water is drained from a drainage mechanism corresponding to the predetermined amount. In general, a certain sealing depth is left inside, and in the draining operation, an external force by an electric signal is applied to a drain valve to drain. That is, it is a premise of the drainage technology that a predetermined amount of the drain stays in the air tank so that there is a residual drain even when the drain is hit. In the timed drainage method, the drainage operation is not performed in proportion to the amount of drain stored in the air tank.Therefore, the drain accumulates inside and the drainage operation is performed. There is a concern such as the automatic drain drainage system.

A more practical drain valve can be obtained if an external force that provides a cheap and stable operation can be used instead of the above-mentioned electric type to automate the operation of the drain drain valve. The following illustrates a similar prior art in FIG. 9 of the drawings herein.
This is a control valve described in Japanese Patent Publication No. 42-13684. According to the publication, the control valve 35 controls the main fluid in accordance with the state of the main fluid, in accordance with the state of the main fluid, in the open state of the valve body 88B and in the external fluid from the communication pipe through the guide hole 34 provided in the upper part. Is caused simultaneously by interlocking with the shaft 85 to be moved up and down, and the vertical movement is received from the lower pressure piston 86B of the shaft 85 through the pressure gas supply hole 33 provided at the lower portion. The valve is opened and closed by acting on the control gas.

[0005] The control valve 35 is used together with a pair of control valves 35 having different inflow directions (not shown) for distributing and transferring two useful fluids in different states. That is, when the main fluid flows through one valve, the main fluid is combined so that the fluid does not pass through the other valve. This is the operation of the valve body and the use of a control gas. That is, this conventional example corresponds to one type of pneumatic control valve that uses a dedicated control air pressure instead of an electric type.

[0006] However, the above-mentioned prior art is not suitable for drainage.
It is not prior art of the exhaust valve. On the other hand, the
Japanese Patent Publication No. 38-21135 is known as a line technology.

Next, an embodiment of the present invention will be described with reference to the drawings. As described above, in the embodiment of the air source device with the pressure switch control mechanism, the control method uses the pressure switch to detect the pressure in the air tank without using the control air C, and electrically controls the control value by the air. This is a method of feeding back to the source device. Therefore, the control result is shown in FIG.
Since it appears in the load airflow on the discharge side of the air compressor 4, a new release pipe 63 that connects the discharge side pipe 51 and the pipe 53 of the release valve 61 is newly provided, and the supply is supplied to the drain discharge valve 8 therefrom. The control airflow C is taken out. By newly providing the control circuit 6 and making the control airflow C available, the internal pressure of the air tank 20 is reduced, and when the compressed air is replenished, the air tantalum 20 Drain discharge valve 8 maintained at almost the same pressure as inside
The internal pressure of (1) receives the control air C from the release pipe 63 into the drain discharge valve 8 and pushes up the piston to start the drain discharge process.

In the embodiment of the air source device with an unloader control mechanism, as shown in FIG. 2, the unloader pipe 65 is a compressed air flow path and is used for its control function. It is assumed that the control circuit 6 is used.
The control air C supplied from the control circuit 6 to the drain discharge valves 8 is supplied when the air source device is not loaded. After the supply is started, a drain discharge step of the drain discharge valve 8 is started, which is the same as that obtained by the pressure switch method.

The drain discharge valve 8A of the present invention is shown in FIG.
As shown, the frame structure is made of iron or A1, or FRP
The material and processing method are selected and made according to the internal pressure resistance conditions, and the resin is used. The upper and lower valve bodies 87 and 88 of the piston 84 have high wear resistance on the surface and preferably have elasticity in order to improve the seat diameter.
The size of those valve bodies is
It is selected to be at least large enough to cover them.
The pressure receiving plate 89, which is a main element for moving the piston 84 up and down,
The size is selected according to the control pressure of the air tank 20 to be provided and the total resistance exerted by the entire piston mechanism during its operation. The illustrated drain flow of the drain discharge valve 8A
The input and output accounts are screw-in, but may be piped by a one-touch, practical and sealed connection technique available, not shown here.
In the embodiment, the control air inflow account 95 is illustrated on the side surface, but may be disposed on the bottom surface of the lower frame 90 directly below the pressure receiving plate 89.

In FIG . 8, when the control airflow C is not supplied to the drain discharge valve A8, the internal pressure of the air tank 20 for accumulating compressed air from the drain inflow account 93 is received inside the drain discharge valve 8A. As a result, the upper valve body 87 of the piston 84, which has been pushed up in the previous state, is pushed down, and a space is created between the upper valve body 87 and the valve seat 91 in the drain inflow account 93, and the lower valve body 88 of the piston 84 The user sits on the valve seat 92 of the drop account 79 to close the space between the upper skeleton 80 and the lower skeleton 90. From the separated space, the drain D in the air tank 20 moves to the drain pool 98 in the drain discharge valve 8A, and the drain D is filled until the drain tank 98 fills the internal volume or until the air tank 20 runs out of the drain D. Store D.

Control air flow C sufficient to operate piston 84 of drain discharge valve 8A upward is supplied to control air inflow account 95. The control air flow C pushes up the pressure receiving plate 89 in the air chamber 78, ends the state in which the lower valve body 88 of the piston 84 is seated on the valve seat 92, starts to separate them from each other, and While opening the space obstruction, the upper valve body 87 is connected to the valve seat 91 in the drain inflow account 93.
Until the communication with the air tank 20 is closed, the pressure receiving plate 89 keeps moving upward. And control air C
While the operation is continued, the upper valve body 87 and the valve seat 91 are kept sealed. As a result, while the drain discharge valve 8A and the air tank 20 remain in the isolated state, the drain reservoir 9
The drain D stored in 8 flows out from the drain drop account 79 opened to the lower space, and a drain moving flow R is generated toward the drain discharge account 94, so that a drain discharge step is performed.
When the drain discharge step is completed, the drain discharge valve 8
Even if there is no drainable drain in A, the piston 84
The upward position of is maintained.

When the compressed air is stored in the air tank 20, fine dust mixed together with the dust, mud in which the lubricating oil in the pipes settled in the tank 20, and generated when the fine dust and oil were mixed and grown. A relatively viscous settling refuse such as refuse is generated. These dusts generally adhere to a valve body such as a valve or a valve seat, and impair the hermeticity. Figure 5 is a dart
4 shows a drain discharge valve 8B having a pocket 11; The drain discharge valve 8B having the dirt pocket 11 captures this kind of sedimentation inhibitor in the dirt pocket 11, and contacts all the built-in valve elements and valve seats, which are opening and closing elements of the drain discharge valve 8B. Protects the contact surface and the part that hinders the vertical sliding operation. As a function of the container adapter, the drain discharge valve 8 whose capacity is increased by the container adapter 10 is used for a long-time compression operation of the compressor, in the case of a compressor having a large amount of air and a large horsepower, or when the humidity of the intake air of the compressor is low. Even if a large amount of drain is generated in many cases, it can be stored in the drain drain valve.

In the description of the embodiment of the present invention, the description has been made based solely on the compressed air source device 1. However, other drain generation devices 2 having similar problems, for example, a certain work device having a pneumatic application circuit, may be used. By applying the automatic drain discharge device 7, an inexpensive and useful embodiment can be provided.

[0032]

[Effect of the Invention] The drain discharge valve used in the automatic drain discharge device of the present invention has a container and a volume set under optimum conditions, and the control air introduces only the drain and compressed air accumulated in the fixed volume. When the pressure system is considered to generate a large amount of drainage, the capacity of the container adapter should be reduced accordingly. By increasing it, it becomes possible to respond. In addition, since the pressure receiving air chamber is small, the moving distance of the drive part is short, and the structure is simple, the initial cost and running cost are small, and high reliability, good maintainability, and container adapter are added. The effect of the present invention is good flexibility with respect to load fluctuations caused by the above. Since the automatic drain discharge device of the present invention operates its operating principle in a closed circuit of energy, it ensures the highest independence in its operation, its operation is stable, and the same control system Because the system operates in conjunction with movement, the drain discharge operation using the drain discharge valve described above is performed while maintaining the close relationship of discharging the drain during the supply air operation with the newly generated drain amount brought by the supply air amount. Since there is rationality, the automatic drain discharge is effective without waste and resource saving.
