Description

Valve for opening and closing fluid channel in water purifier

The present invention relates to a flow path opening and closing valve of the water purifier provided in the raw water pipe, and more particularly, to a flow path opening and closing valve of the water purifier for opening and closing the flow path in the main body by operating a pair of disk members stacked so as to rotate mutually.

The flow path opening and closing valve 1 of the water purifier is installed at the inflow side of the raw water pipe 2, preferably, as shown in Figure 1, the adapter (3) connecting between the water pipe (5) and the raw water pipe (2) Connected with

The flow path opening and closing valve 1 controls the supply of raw water to the water purifier 4 through the opening or closing of the raw water pipe 2.

Looking at the internal structure of the flow path opening and closing valve (1) of the water purifier with reference to Figure 2, the valve body 10 is fastened to the peripheral surface of the raw water pipe (2) of the water purifier, the cock to open and close the flow of raw water of the valve body 10 Consists of a cock (20).

Here, one flow path 11, which is a movement path of raw water introduced through the adapter 3, is formed inside the valve body 10. The cock part 20 includes a handle 21 protruding to the outside of the valve body 10 and a rubber opening / closing hole 22 connected to the handle 21 and accommodated in the valve body 10.

Rotating the handle 21 of the cock part 20 to the left and right to open or close the opening 22 to communicate or block the flow path 11 of the valve body 10.

However, the conventional channel opening and closing valve as described above has a problem that the opening and closing operation is not smooth and stiff when the flow opening and closing valve is used for a long time because the opening and closing opening is made of rubber or Teflon material for watertightness when the knob is rotated. there was.

In addition, when the flow path opening and closing valve is used for a long time, the durability between the valve body and the cock is lowered, which causes a problem of frequent leakage.

In addition, when the flow path opening and closing valve is shut off, the residual pressure is naturally generated inside the water purifier. For example, when an operator separates the filter connection part for an after-service, such as a filter replacement, the residual pressure is generated due to the residual pressure generated in the water purifier. There was a problem that can not proceed smoothly while working.

The present invention has been made to solve the above problems, firstly, it is an object of the present invention to provide a water flow opening and closing valve of the water purifier so that the operation is made smoothly and the leakage phenomenon is prevented even in long-term use.

Secondly, an object of the present invention is to provide a channel opening / closing valve of a water purifier that efficiently removes the residual pressure applied to the inside of the water purifier by manipulating the flow path so that the work such as filter replacement can be performed conveniently.

If the user rotates the handle 71 in one direction, the loading member 73 rotates at the same time, and the second disk member 60 rotates by the rotation of the loading member 73 in the second flow path 40b. Is as shown in FIG.

If the flow path opening and closing valve 30 of the present invention is in the state of FIG. 8, since the first flow path 40a of the main body 40 is completely blocked, the raw water introduced through the inlet port 41 of the main body 40 is The second disk member 60 blocking the first through hole 51 of the first disk member 50 can no longer flow to one side. Therefore, the channel opening and closing valve 30 can no longer supply raw water to the filters of the water purifier.

8 is a state in which the second flow path 40b of the main body 40 is open. Normally, the residual residual pressure generated while blocking the supply of raw water to the water purifier is introduced through the first outlet port 42a of the main body 40, and the residual pressure introduced into the main body 40 is generated by the first disc member 50. After passing through the four through holes 54, the residual pressure is the short groove of the second disk member 60 in communication with the fourth through hole 54 and the third through hole 53 of the first disk member 50 ( 62 is discharged through the step groove 62, the residual pressure is discharged to the second outlet port 42b while passing through the third through hole 53 of the first disc member 50 again.

Thus, the residual pressure drawn out through the second outlet port 42b of the main body 40 is discharged to the second pipe 92.

Although not shown in detail in the drawing, if the second pipe 92 is directly connected to the wastewater discharge pipe (not shown) provided on one side of the membrane filter (not shown) of the water purifier, eventually discharged to the second pipe 92 The remaining residual pressure may be collected in a wastewater storage tank (not shown) which is the final destination of the wastewater discharge pipe.
