Description

Six-way valve device attached to double filter {6-way valve equipment in doubles filter}

In general, in most industrial sites, a filter is used to filter out foreign substances or impurities contained in various fluids by using a filtration filter to extract the purified fluid and use it as industrial water. Foreign matters are attached to the outer surface.

In other words, in order to increase the purification efficiency of the filter fluid, it is necessary to clean the filter, such as periodically cleaning or replacing the filter.

On the other hand, when replacing or disassembling and cleaning the filtration filter provided inside the filter, it is necessary to temporarily stop the operation of the filter. In most industrial sites where the continuous purification of the fluid must be performed, There has been a closed end that cannot maintain cleanliness, and the development of a double filter that combines a pair of different filters with a six-way valve to control the flow direction of the fluid enables continuous purification of the fluid. It can be seen that the general coupling structure of the double filter using the six-way valve as described above and the circulation structure of the fluid are disclosed in Utility Model Registration No. 20-0400790 (6-way valve).

In the case of the above-mentioned six-way valve (Utility Model Registration No. 20-0400790), the inflow grooves and the discharge grooves are formed in the six-way valves along the rotational direction of the rotating shaft having different inflow grooves and discharge grooves in the inner center in which the hollow part is formed. The connection ports are selectively opened and closed, and each connection port is connected to a different fluid input unit and a fluid output unit of the double filter through a separate connection pipe.

Specifically, the inlet grooves and the outlet grooves formed on the rotary shaft have a structure in which the input / output portions of different fluids of the double filter and the input / output connection ports of the six-way valves are connected in a straight line through a separate connection pipe. The inlet and outlet grooves respectively formed on the upper and lower parts of the rotary shaft selectively communicate with the different fluid input and fluid output parts of the double filter according to the rotation direction of the rotary shaft, so that the fluid supplied from the input port of the six-way valve is introduced into the inlet groove. Purified fluid selectively supplied to different fluid inputs of the double filter through each filtration filter provided in each of the double filters is discharged to the output port through the discharge groove of the different fluid input and the six-way valve through It becomes the structure that becomes.

However, in the case of the six-way valve using the inflow groove and the discharge groove as the connection port, the joints are required to be watertight, so that a very large operating force is required to change the rotational direction of the rotating body to change the flow direction of the fluid. As a result, inconveniences that cannot be used as an industrial filter for refining a large amount of fluid have existed.

Furthermore, the six-way valve as described above has a structure in which the outer circumferential surfaces of the inflow groove and the discharge groove of the rotating body used as the connection port are rotated along each outer diameter of the six-way valve's input / output port and the double filter's fluid input / output part. Various closures, such as the problem that the joining of the member is very difficult and the disc replacement cycle is shortened due to the shortening of the disc replacement cycle such as the disc wear is accelerated by frequent rotation of the joint surface disc. This was there.

The first object of the present invention for solving the above problems is to incorporate a pair of piston assembly that moves in both directions inside the valve body, to selectively perform the filtration operation of a pair of different filters, It is to implement a six-way valve device attached to a double filter that can quickly purify a large amount of fluid without interrupting the filtration operation.

Another object of the present invention is to sequentially stack a plurality of disk members on both ends of the piston rod portion constituting the piston assembly in order to extend the replacement period while minimizing the damage of each disk member, filter It is to implement a six-way valve device attached to the double filter that can improve the watertightness to the joint surface of the valve body.
