Description

Flow switch

The present invention relates to a flow direction switch, and more particularly to a switch mounted on a filter device for controlling the flow direction.

The existing liquid filter uses an internal filter core tube to filter an input liquid such as water or oil, and after the liquid is filtered through the filter tube, the filtered liquid is output and used.

Although the existing filter can filter liquid such as water or oil for use, since the filter core tube will be blocked after long-term use, it is necessary to replace or clean the filter core tube. At this time, it is necessary to stop the operation of the filter. Even if the entire set of machines equipped with this filter is stopped, it is possible to disassemble or replace the filter core tube, which is not only cumbersome to operate but also incapable of continuously filtering, resulting in inefficient work.

In order to solve this problem, the prior art has a problem of troublesome operation and affecting work efficiency when the filter is replaced or cleaned. Therefore, in order to solve this problem, the present invention mainly proposes a flow direction switch that can control the flow of liquid to the automatic cleaning filter tube through the flow direction. The switcher counter-flows the filtered liquid and achieves the purpose of cleaning the filter core tube without suspending the filtration operation.

The present invention provides a flow direction switch comprising: a body having an inlet formed at one end and an outlet formed at the other end a first outer groove and a first inner groove are recessed on one side of the bottom surface, and a second outer groove and a second inner groove are recessed on the other side of the bottom surface; an input flow channel having one end connected to the inlet The other end is connected to the first outer groove and the second outer groove; an output flow path is connected at one end to the outlet, and the other end is connected to the first inner groove and the second inner groove; a switching valve that is inserted into the body and located on the input flow path, and switches to control the input flow path to communicate with the first outer groove or the second outer groove; and is movably inserted on one side of the body a first control valve that selectively controls the first inner groove to communicate with or not communicate with the first outer groove; and a second control valve movably inserted on the other side of the body, Optionally controlling the second inner groove to communicate or not communicate with the second outer groove.

According to the above technical means, after the flow switching device of the present invention is respectively installed with the filter tube on the first outer groove and the second outer groove, one of the filter tubes can be controlled by the switching control of the switching valve. When the filtration operation is carried out, another filter tube can be simultaneously cleaned, and the work efficiency can be improved.

The first positioning ring 33 is sleeved on the upper portion of the first control rod 32, and can be abutted or away from the top surface of the first base 31 as the first control rod 32 moves up and down to indicate the first The position of a lever 32.

The first spring 34 is sleeved in the lower portion of the first control rod 32 and received in the first inner groove 15 and abuts against the end surface of the first inner groove 15 at one end, and the other end abuts against the same The first stopper 35.

The first stopper 35 is a disk body disposed in the first inner groove 15 , and a first stud 350 protrudes from a center of the top surface thereof, and is fixed to the first through the first stud 350 The first screw hole 321 of the lever 32 is mounted.

The first control plug 36 is screwed between the first inner groove 15 and the first outer groove 13 and is provided with at least one first control hole 360 that communicates with the first inner and outer grooves 15 and 17. . When the first control rod 32 is pressed down to abut the first ball 312 against the circumferential surface of the rod body, the first stopper 35 is pushed against the first spring 34 and closely abuts against the top of the first control hole 360; When the first control rod 32 is pulled up to cause the first ball 312 to be clamped to the first positioning groove 320, the first stopper 35 leaves and opens the first control hole 360.

The structure and the original part of the second control valve 40 are identical to the first control valve 30, but the position of the corresponding control unit 40 is different, that is, the bottom end of the second control rod 42 of the second control valve 40 extends into the second concave portion. In the groove 17, the second spring 44 and the second stopper 45 are located in the second inner groove 17, and the second control plug 46 is screwed between the second inner groove 17 and the second outer groove 14.

The first filter tube 50 is mounted on the first outer recess 13 of the body 10, and a first sealing hole 51 is formed in the bottom, and a first sealing plug 52 is locked on the first sealing hole 51; The second filter tube 60 is mounted on the second outer recess 14 of the body 10, and a second sealing hole 61 is formed in the bottom. A second sealing plug 62 is locked on the second sealing hole 61.

A first filter core tube 53 is disposed in the first filter tube 50. The first filter core tube 53 is disposed on the first control plug 36 and communicates with the first control hole 360.

Since the output flow path 102 simultaneously communicates with the first inner groove 15 and the second inner groove 17, the filtered clean liquid (dashed arrow) flows from the output flow path 102 to the second inner groove 17 at the same time, and passes through The second control hole 460 of the control plug 46 flows into the interior of the second filter core tube 63. At this time, the clean liquid is washed outwardly to the second filter core tube 63, and then flows to the second sealed hole of the second filter tube 60. 61 discharge, you can complete the cleaning operation.

When the first filter tube 50 and the first filter core tube 53 are to be cleaned, referring to FIG. 1 and FIG. 6, the joystick 22 of the flow switcher of the present invention is turned to be close to the inlet 11 side, and the first control is pulled up. The valve 30 and the second control valve 40 are depressed, and the first sealing plug 52 of the first filter tube 50 is detached.

The liquid to be filtered (solid arrow) flows sequentially through the inlet flow path 101, the second outer groove 14, the second filter tube 60, and the second filter core tube 63 from the inlet 11, and the filtered liquid (dashed arrow) Flowing through the second control hole 460 of the second control plug 46, the second inner groove 17, the output flow path 102, and finally flowing out from the outlet 12, while the filtered liquid in the output flow path 102 is simultaneously flowed back to the first inner portion. The groove 15, the first control hole 360 of the first control plug 36, the first filter core tube 53, and the first filter core tube 53 are washed outward, and then discharged to the first sealing hole 51 of the first filter tube 50. , you can do the filtering At the same time, the cleaning operation is carried out together.

According to the above structure and operation, the flow switching device of the present invention can perform the cleaning operation at the same time as the cleaning operation without stopping the operation of the filter, thereby achieving the purpose of improving the working efficiency.
