Description

Pressure fluid metering and supply regulator {FIXED VOLUME DELIVERY AND DELIVERY CONTROL DEVICE OF PRESSUREIZED FLOWABLE MATERIAL}

The present invention relates to a pressure fluid quantitative supply and supply control device, and more specifically, to supply the fluid flowing at a predetermined pressure by a predetermined amount by using a pressure and an elastic force of the fluid or a fixed amount of pressure fluid configured to control the supply amount and It relates to a feed regulator.

In general, as a means of supplying a certain amount of fluid or regulating the amount of supply of fluid using pressure or power, solenoid valves, pumps, especially metering pumps, and compressed air or gas are used to provide a piston or diaphragm. There are devices that move and supply grease, adhesives or various fluids.

Since the above devices regulate the amount of fluid supplied by using a flowmeter, it is difficult to precisely supply the amount of fluid or a complicated device to control the amount of fluid supplied, resulting in high failure rate, large volume, and heavy weight. It is inconvenient to use.

In addition, manual nebulizers, syringes, and manual injectors, which manually supply fluids, require a lot of effort and time to supply fluids, and are difficult to use when the supply amount of the fluid is more than 100 cc or the viscosity of the fluid is high.

The conventional fluid quantitative supply and supply control device using a power source transfers a fluid supplied at a predetermined pressure by a compression action of a compressor through a conveying pipe a predetermined distance, and continuously or intermittently quantitatively through a discharge port connected to the conveying pipe. It includes an injector, an ejector, an atomizer, a pump, a fluid movement speed regulator, etc., in which injection, discharge, or transfer is made, and an automatic feeder equipped with a numerical control device.

Since the fluid discharge or transfer operation using the conventional fluid quantitative supply and supply control device using the power as described above is continuously supplied with a fluid of a predetermined pressure by a pump or a compressor, the operator can arbitrarily adjust the discharge amount as needed It is difficult, and even when the automatic control device is attached, the error of the supply amount is severe due to variations in pressure, temperature, viscosity, etc. in the transfer pipe.

In addition, in the case of pesticides can not control the spread of the drug, if the drug is sprayed more than necessary, the drug will remain in the soil and crops, resulting in environmental pollution and cause great damage to animals and people who consume the crops do.

And excessive spraying of the drug is unnecessary consumption, thereby increasing the cost.

An object of the present invention is to solve the problems arising in the supply method and the supply control method of the fluid has been used to date as described above, by supplying a predetermined amount of the fluid flowing at a predetermined pressure by using the elastic force and the pressure of the fluid Or to provide a pressure fluid supply and supply control device configured to control the supply.

The pressure fluid quantitative supply and supply control device proposed by the present invention is formed with a pressurized chamber into which a fluid of a predetermined pressure transferred through a fluid transfer pipe and a quantitative discharge chamber are formed, and the volume of the pressurized chamber and the quantitative discharge chamber using the pressure and elastic force of the fluid. And a fixed quantity dispensing device for supplying a fluid by a predetermined amount by interlocking with the pump, and a fluid connected to the above-mentioned fixed quantity discharging device and discharged by a predetermined amount from the fixed quantity discharging device to a used device or a fluid supply pipe or inflowed from a fluid transfer pipe. And a valve assembly operable to supply the fluid to the metered discharge chamber.

The metered discharge device is formed with a pressurizing flow path for guiding a fluid having a predetermined pressure supplied through the fluid transfer pipe to the pressure chamber, and a supply flow path for guiding a fluid having a predetermined pressure supplied through the fluid transfer pipe to the valve assembly. And a discharge passage for communicating the metered discharge chamber and the valve assembly with each other.

The metered discharge device is provided with a diaphragm for varying the volume of the pressure chamber and the metered discharge chamber in conjunction with the volume or the piston provided with an elastic member.

The quantitative discharging device further includes quantitative control means for adjusting the volume change of the pressurizing chamber and the quantitative discharging chamber.

The valve assembly is provided with a discharge port for discharging the fluid of a predetermined pressure to the device or the fluid supply pipe, and the spool is provided to communicate the discharge flow path and the discharge port or to communicate the discharge flow path and the supply flow path, Install a drive lever to operate one spool.

The spool cuts off the communication between the discharge flow path and the discharge port and then communicates with the discharge flow path and the supply flow path, cuts off the communication between the discharge flow path and the supply flow path, and installs the discharge flow path and the discharge port.

The valve assembly further includes a return spring for assisting the operation of the spool, and a valve control device for controlling and controlling the operation of the spool or the driving lever.

In the pressure fluid supply and supply control device of the present invention configured as described above, the drive lever of the valve assembly is positioned at the inflow position, and the spool blocks the connection between the discharge port and the discharge, In the communicating state, when a fluid having a predetermined pressure flows into the pressurizing flow passage and the supply passage through the fluid transfer pipe, the fluid introduced through the pressurizing passage flows into the pressurizing chamber and the fluid flows into the supply passage. Since the supply flow path and the discharge flow path are in communication with each other, the discharge flow path flows into the discharge chamber.

When the fluid of the same pressure flows into the pressure chamber and the metered discharge chamber as described above, the piston moves to the pressure chamber by the elastic force of the elastic member or the elastic membrane is deformed toward the pressure chamber by the elastic force so that the volume of the volumetric discharge chamber As the volume increases and the volume of the pressurized chamber becomes small, the fluid continuously flows into the filled volumetric discharge chamber.

In such a state, when the driving lever of the valve assembly is positioned at the discharge position, the spool blocks communication between the supply flow path and the discharge flow path, and then communicates with the discharge flow path and the discharge port. The movement is blocked by the spool of the valve assembly, the fluid passing through the pressure passage continues to flow into the pressure chamber.

As described above, when the fluid moving to the supply passage is blocked and the fluid continues to flow into the pressure chamber, the pressure in the pressure chamber overcomes the elastic force of the elastic member and moves the piston to the metered discharge chamber, or overcomes the elastic force of the elastic membrane and the elastic membrane is fixed. The volume of the pressurizing chamber becomes larger and the volume of the metered discharge chamber becomes smaller.

As described above, as the volume of the metered volume discharge chamber decreases, the fluid of the metered volume discharge chamber that decreases in volume flows out through the discharge passage and is supplied to various equipment through the discharge port.

At this time, it is possible to control the discharge amount of the fluid discharged at one time by adjusting the moving distance of the piston by using the quantitative adjustment means.

According to the pressure fluid supply and supply control device of the present invention made as described above, each time the drive lever of the valve assembly is operated once the piston moves a predetermined distance or the elastic membrane is deformed to discharge the fluid by a certain amount It is possible to supply the fluid by a certain amount. By attaching the valve control device to the driving lever, the function of controlling the automatic supply of the fluid by numerical control is given.

First, as shown in FIG. 1, the driving lever 80 of the valve assembly 60 is assembled to the handle 85 through the rotation pin 83 by the elastic force of the return spring 87. The inflow position rotated about the vertex portion, that is, the opening and closing portion 74 of the spool 70 is in the inflow state located in the discharge passage 69.

In the inflow state as described above, the fluid having a predetermined pressure introduced through the inflow pipe 11 to which the fluid transfer pipe 2 is connected is introduced into the pressure chamber 31 through the first flow path 15, which is a pressure flow path. At the same time, the second flow path 16 and the guide member 38 and the third flow path 25 are introduced into the fifth flow path 65.

The fluid introduced into the fifth flow path 65 flows into the sixth flow path 66 through the opening and closing flow path 67 and the connection flow path 68, and flows into the sixth flow path 66 as the discharge flow path. The fluid is introduced into the metered discharge chamber 32 through the fourth passage 26.

At this time, since the fluid of the same pressure flows into the pressurizing chamber 31 and the metered discharge chamber 32, the piston 30 moves toward the pressurizing chamber 31 by the elastic force of the elastic member 40. The volume of the volumetric discharge chamber 32 is increased to the maximum and the volume of the pressure chamber 31 is at a minimum. The fluid having a predetermined pressure flowing into the inlet 11 is large in volume. Will fill (32).

In the above state, as shown in FIG. 2, the driving lever 80 of the valve assembly 60 is pressed against the handle 85 so as to discharge the fluid to the user device 4, and the driving lever 80. ) Is rotated about the vertex portion assembled to the handle 85 by the rotary pin 83 is located in the discharge position, the spool 70 of the valve assembly 60 is the opening and closing portion 74 of the opening and closing flow path The discharge state located at 67 is obtained.

The flow is stopped by the opening and closing portion 74 of the.

In addition, the fluid in the metered discharge chamber 32 is discharged by connecting the fourth passage 26 and the sixth passage 66 and the connecting passage 68 and the discharge passage 69 which are discharge passages. The outflow to 61 is possible.

In this state, since the fluid having a predetermined pressure is continuously introduced into the pressurizing chamber 31 and the fluid of the metered-out discharge chamber 32 can be discharged, the pressure of the fluid filled in the pressurizing chamber 31 is the above-mentioned. The elastic force of the elastic member 40 is overcome and the piston 30 is moved toward the fixed quantity discharge chamber 32.

Therefore, the fluid filled in the metered discharge chamber 32 is pushed by the piston 30 to discharge the fourth flow path 26, the sixth flow path 66, the connection flow path 68, and the discharge flow path 69. And flows out through the discharge port 61 and is supplied to the user device 4.

The discharge of the fluid is made.

When the driving force of the driving lever 80 is removed, the driving lever 80 is moved to the inflow position by the elastic force of the return spring 40, and the opening and closing portion 74 of the spool 70 is discharged. The inflow is located at (69).

(68) → The sixth flow path (66) → The fourth flow path (26) passes through the metered-out discharge chamber (32).

When the fluid having a predetermined pressure flows into the metered discharge chamber 32 as described above, the piston 30 moves to the pressure chamber 31 by the pressure of the fluid and the elastic force of the elastic member 40, and the pressure chamber ( The fluid filled in 31 is discharged through the first channel 15 and combined with the fluid flowing through the inlet 11 to be supplied to the second channel 16.

As described above, the piston 30 is moved by the elastic force of the elastic member 40 so that the volume of the pressure chamber 31 becomes the minimum state and the volume of the metered discharge chamber 32 becomes the initial state. .
