Description

Fluid piston pump using air pressure {COMPRESSOR AIR LIQUID PISTON PUMP}

The present invention relates to a fluid piston pump operating by air pressure, and in particular, to simplify the structure and to improve the function as a fluid pump.

In general, the fluid piston pump using the air pressure widely used in the industrial field has various control valves for the reciprocating operation of the piston, so that the manufacturing cost increases and the volume of the product is not easy to handle and install. .

In addition, if the configuration is complicated, failures can occur frequently, and if all parts are disassembled and assembled during repair due to the failure, the sealing of each part is not properly performed, and thus the original performance cannot be maintained.

In particular, the various control valves had a number of problems, such as poor performance of the fluid piston pump because the reciprocating speed of the piston is lowered due to the lack of the associated continuous operation.

In order to solve the above-mentioned problems, the present invention installs a cycling valve piston inside the cycling piston to reciprocate in an associated operation during operation by compressed air, thereby reducing manufacturing costs and troubles with a simple configuration, and miniaturizing it. It aims to improve the function as a fluid piston pump by maximizing the reciprocating speed of the piston.

In order to achieve the above object, the present invention blocks the air flow passage formed between the cycling piston and the cycling piston when the air is compressed through the operation chamber of the upper cylinder so that the cycling piston and the cycling valve piston are lowered together along the center rod. When descending, the air flow control hole of the center rod is opened by the cycling valve, and when the cycling valve piston rises from the cycling piston, the air flow passage is opened, so the compressed air is discharged through the lower operating chamber and the compressed air is discharged. Cycling valve pistons and cycling pistons repeat the return operation by the spring force of the juice spring, and the bulging protrusion protruding from the bottom of the cycling piston is reciprocated up and down.

Hereinafter, the specific technical configuration and operation of the present invention will be described in detail.

1 is a schematic cross-sectional view of the present invention, in which the suction head cap 2 and the outlet cap 3 block a cylinder 4 and the cylinder 4 and the center rod 6. Reciprocating up and down along the bottom) and the cycling piston 10 protruding in the bottom portion, the cycling valve cylinder 12 fixed to the inside of the cycling piston 10 and the cycling valve cylinder 12 It consists of a cycling valve piston 14 reciprocating up and down accordingly.

In the above, the suction head cap 2 of the upper part of the cylinder 4 has a suction port 16 formed on one side thereof, and the upper operation chamber 18 and the cycling valve head 20 formed between the cycling piston 10 and the upper part thereof. In order to communicate with the auxiliary operation chamber 22 formed between the center head 6 and the center portion 6 of the bottom surface of the suction head cap 2, an air flow control hole 24 is formed at an appropriate position. Secure the connection vertically.

The cycling piston 10 inside the cylinder 4 allows the juice spring 26 elastically installed between the outlet cap 3 to be elastically supported upwards and an air flow connecting the bottom through-hole 28 from the inner upper portion thereof. By forming the passage 30 to operate the cycling valve piston 14 to open and close the air flow passage 30 and the space 34 in communication with the lower operation chamber 32 between the cycling valve cylinder 12 And a lower portion of the center rod 6 is inserted into the inner portion of the branching protrusion 8 protruding to the bottom thereof so that the cycling piston 10 reciprocates up and down along the cylinder 4 and the center rod 6. do.

The cycling valve cylinder 12 fixed to the inner bottom of the cycling piston 10 has a tricycle 36 protruding from the top of the cycling valve piston 10 to be supported from the top thereof, The inner diameter is smaller than the inner diameter of the cycling valve cylinder 12 and the diameter of the cycling valve head 20 to control the operating distance of the cycling valve piston 14 and the air flow passage 30 by the cycling valve head 20. ) Open and close.

The cycling valve piston 14 operating along the cycling valve cylinder 12 allows the valve spring 40 installed in the valve operation chamber 38 of the cycling valve cylinder 12 to be elastically supported upward, and the cycling valve piston The body portion 42 between the upper portion 14 and the cycling valve head 20 is formed to have a small diameter so that the air flow passage 30 is secured therebetween, and the upper and lower portions are formed at the inner central portion of the body portion 42. A cycling valve 44 whose length is shorter than the upper and lower lengths of the air flow control holes 24 of the center rod 6 is formed, and the auxiliary operation chamber 22 and the valve operation of the upper part are arranged with the cycling valve 44 interposed therebetween. Allow passages 46 and 48 to form seals 38.

Reference numeral 50 is an outlet.

In the present invention, as shown in FIG. 2, a part of the compressed air flowing into the upper operation chamber 18 through the suction port 16 of the suction head cap 2 is formed in the auxiliary operation chamber 22 formed in the upper part of the cycling valve head 20. ), The cycling valve piston 14 descends the maximum from the cycling valve cylinder 12 so that the upper cycling valve head 20 blocks the air flow passage 30 formed between the cycling piston 10. And in this state is descending together along the cycling piston (10) which is directly connected to the lowering operation of the pawler (8) protruding on the bottom of the cycling piston (10).

When the cycling piston 10 reaches the air flow control hole 24 formed vertically long in the center rod 6, as shown in FIG. 3, when the cycling piston 10 is operated, the air flow control hole 24 Since the upper and lower length cycling valves 44 are interposed therebetween, the passages 46 and 48 connecting the auxiliary operation chamber 22 and the valve operation chamber 38 of the cycling valve head 20 are communicated with each other. The compressed air of the operation chamber 18 flows into the valve operation chamber 38 through the air flow control hole 24.

In the above, when the compressed air of the upper operation chamber 18 flows into the valve operation chamber 38 through the air flow control hole 24, the cycling valve piston 14 is removed from the cycling valve cylinder 12 as shown in FIG. Since the air flow passage 30 was blocked by the cycling valve head 20, the compressed air of the upper operation chamber 18 was instantaneously vented through the air flow passage 30 and the bottom of the cycling piston 10. And it is discharged to the outlet 50 of the outlet cap (3) through the lower operating chamber (32).

When the upper operation chamber 18 is at atmospheric pressure due to the discharge of compressed air, the cycling piston 10 is raised by the elastic force of the juice spring 26, as shown in FIG. When the protruding cycling valve head 20 first comes into contact with the bottom surface of the suction head cap 2, the air flow passage 30 is blocked by the rising of the cycling piston 10.

At this time, the compressed air of the valve operation chamber 38 in which the internal pressure remains is discharged to the lower operation chamber 32 as it is communicated with the space 34 by the air flow control hole 24 of the central rod 6. Atmospheric pressure and the maximum rise of the cycling piston 10 is directly connected to the riser operation of the blander 8 to complete one complete reciprocating operation. This reciprocating operation is continuously and repeatedly supplied by supply of compressed air through the inlet 16 Will be done.

As described above, the present invention provides a cycling valve piston inside the cycling piston 10.

(14) It is a dual structure installed, which allows the reciprocating operation by linked operation by compressed air, so the structure is simple, which can reduce manufacturing cost and failure rate, and also can be miniaturized. In particular, the reciprocating operation speed of the piston can be maximized. It is a useful invention to obtain a fluid piston pump with much improved function.
