Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a switching valve that is attached to a water faucet so that it can be used selectively between a water purifier and a water supply.

[Conventional technology]

Water purifiers used in homes are connected to a water faucet through a water purification switching valve, and by operating the switching valve, tap water and purified water can be used alternately, and the water can be turned off. However, in order to do so, it was necessary to rotate the valve body 180 degrees.

[The problem that the idea attempts to solve]

With conventional switching valves for water purifiers, the valve body must be rotated 180 degrees to switch between the three stages of direct opening, side opening, and water shutoff, making operation cumbersome.

[Means to solve the problem]

The switching valve according to the present invention has a vertical flow channel having an inlet and an outlet opening at the upper and lower end faces, communicating with an intermediate part of the flow channel, and a side inlet and a side outlet on the outer peripheral surface, respectively, in the left and right directions. A first communication hole in the vertical direction that can connect the inflow port and the outflow port, and a first communication hole that opens in the vertical direction and that can connect the inflow port and one side outlet, which are opened at intervals in the valve box. A horizontal cylindrical valve body is fitted, which has a second communication hole and a third communication hole that opens in a right angle direction and can connect the side inlet and the outlet, and is rotatable around a horizontal axis. together,
By rotating an operating lever fixed to the valve body up and down to rotate the valve body, the first flow hole and the inlet and outflow ports are in a direct open position, and the second flow hole and the third flow hole are respectively opened. It is designed to be able to take three switching positions: a side open position where the flow hole communicates with the side inlet and a water cutoff position where the flow hole does not communicate with the inlet.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 3, the valve box 1, which has a substantially cylindrical shape and faces in the vertical direction, has upper and lower end surfaces 1a and 1b.
A flow path 2 with a circular cross section is formed passing through the center of the
A flanged holder 4 is screwed into the inlet 3 of the upper end surface 1a.

An annular connecting portion 6 having a male thread 6a cut on its outer periphery is provided downwardly on the opening edge of the outlet port 5 on the lower end surface 1b.

A horizontal valve hole 7 having a circular shape in side view is provided through the vertically intermediate portion of the flow path 2 .

The rear wall 1c of the valve box 1 has left and right sides 1 facing in the front-rear direction.
A pair of small-diameter side flow passages 8 and 9 are bored, and at the rear end of each flow passage 8 and 9, there is a stepped cylindrical side outlet 10 and a side inlet 11 that project rearward from the valve body 1, respectively. They are installed consecutively.

A horizontal cylindrical valve body 12 is fitted into the valve hole 7, and as shown in FIG. A tip portion 12c of the protruding long shaft 12b passes through the valve box 1 and extends outward.

A rear end 13a of an operating lever 13, which has an inverted L shape in plan view, is fixed to the tip 12c of the long shaft 12b.

On the front surface of the valve box 1 facing the free end 13b of the operating lever 13, characters 1d of "purified water,""waterstop," and "raw water" are embossed in order from the top.

As shown in FIG. 4, the valve body 12 has a first straight line in the front-back direction perpendicular to its horizontal axis l.
A communication hole 14 is cut into the first communication hole 14 and an inlet 14 is opened at the front and back of the outer circumferential surface 12d of the valve body 12.
a and the outlet 14b are adapted to be aligned with the inlet 4 and outlet 5 of the valve body 1, respectively.

On the right side of the first flow hole 14, the valve body 12 includes:
A second flow hole 15 facing in the front-rear direction is provided, and its inlet 15a is on the upper surface of the valve body 12, and its outlet 15b is
It opens to the right of the inlet 14a on the front surface of the valve body 12. Note that the entrance 15 of the second communication hole 15
a is a point facing upward and spaced 90 degrees from the axis m of the first communication hole 14 in the circumferential direction;
It opens at 2d.

On the left side of the first flow hole 14, the valve body 12 includes:
A third communication hole 16 that is vertically symmetrical with the second communication hole 15
The inlet 16a is located symmetrically with the outlet 15b across the inlet 14a, and the outlet 16b
is open in the lower surface of the valve body 12 on a vertical plane in the axial direction of the valve body 12, which includes the axis n passing through the center of the inlet 15a of the second communication hole 15.

These first, second and third communication holes 14, 15, 1
6 are mutually independent through holes.

Note that 17 shown in FIG. 3 is a safety valve provided in a through hole that communicates with the flow path 8 and the outside of the valve box 1, and 18 shown in FIG. 2 is a stopper that determines the rotation range of the valve body 12. .

Next, how to handle the switching valve 19 described above will be explained.

First, as shown in FIG.
is brought into contact with the upper surface of the holder 4 at the inlet 3 of the holder 4, and is attached to the holder 4 using the adapter 22 and the tightening cap 23.

A flexible faucet 24 made of a curved pipe is attached to the connecting portion 6 below the switching valve 19.

The inlet 25a of the water purifier 25 containing activated carbon and a filter (not shown) and the side outlet 10 of the switching valve 19 are connected to the conduit 2 through a sleeve 26a.
6, and the outlet 25b of the water purifier 25, the switching valve 19, and the side inlet 11 are connected by a conduit 27.

When the water stop valve 20 is opened with the operation lever 13 in the horizontal state at the water stop position, and the free end of the operation lever 13 is rotated upward to the water purification position corresponding to the word "water purification" above, the water stop valve 20 is opened. As shown in FIGS. 5 and 6, the valve body 12 rotates to a side-open position where the inlet 3 and the second communication hole 15 and the third communication hole 16 and the outlet 5 are connected.

Raw water, i.e. tap water, comes out of the side outlet 10 of the valve box 1 and enters the water purifier 25. The purified water is
It enters from the side inlet 11, passes through the outlet 5 of the valve box 1, and exits through the free-floor faucet 24.

When the operating lever 13 is lowered to the horizontal water stop position as shown in FIG. 1, the inlet 14a of the first flow hole 14 is aligned with the inlet 3 as shown in FIGS. 7 and 8. No, water doesn't flow.

When the operating lever 13 is lowered further from the position shown in FIG. 1 to the open position, the valve body 12 rotates and the inlet 3 and outlet 5 are opened as shown in FIGS. 9 and 10. , are directly connected via the first communication hole 14.

Therefore, tap water exits directly from the adjustable faucet 24 without passing through the water purifier 25.

When the operating lever 13 is raised again, the water stop position shown in FIGS. 7 and 8 is reached, and the outflow of water is stopped.

In the embodiment described above, the switching valve is connected to the water purifier to switch between raw water and purified water, but instead, tap water is connected to a water heating device consisting of water pipes and a heater, and the switching valve is connected to the water purifier to switch between raw water and purified water. It may be possible to switch between the two.

[Effect of idea]

In the present invention, a valve body with three flow holes is provided in a valve box provided with a side flow path communicating with the vertical flow path, and the valve body is moved to the straight-open position using an operating lever.
Since it can be rotated to the side open position and the water stop valve position, water can be easily stopped.
