JP2003082721A - Fluid flow rate quantity adjusting valve - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve a problem wherein a conventional water saving valve must replace loading by preparing another valve each time when changing a water flow rate. SOLUTION: The fluid flow rate adjusting valve solves the problem by a device that several bored holes are applied and combined in the same along the cylinder axis around radial lines from the same center of a circle to and with respective cylindrical shapes divided into two parts so that a flow rate can be variously adjusted only by one piece, bored several holes overlap each other by rotating at an optional angle in the same center of a circle, and the water feeding quantity is changed in several stages by a pair of two pieces by using hole-shaped clearance like the moon wanes and waxes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid passage control valve which is inserted into and installed in any liquid or gas fluid, flow channel pipe, but is generally installed in a shower or tap faucet line using tap water. The present invention relates to a water-saving valve capable of arbitrarily adjusting the amount of water flow in multiple stages with only one piece.

[0002]

2. Description of the Related Art The prior art is (Actual Kaihei 3-41283)
And (Japanese Patent Laid-Open No. 09-49257) and (Patent No. 31891).
Each of 44) was an individual water-saving valve that provided an adjusted flow rate to each.

[0003]

[Problems to be solved by the invention] Even if a user selects a water pressure, a flow rate, a flow rate, a usage condition, etc. in a water pipe to use the above water-saving valve and adopts a model number, the user will be required to change each flow rate later. If there is a change in the situation and you want to change it, there is the inconvenience of having to purchase new specifications many times.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in order to adjust the flow rate in many ways with only one, each of the two divided cylindrical types has several constrictions around the radiation from the same circular center. Combined by applying the same along the axis of the cylinder, and turning several holes with the same circle center at an arbitrary angle, several holes that overlap are overlapped,
The solution was to solve the problem by changing the water flow rate in several stages (4 types in the drawing explanation) by using a pair of hole-shaped gaps such that the age is insufficient.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, since a variable flow rate can be designated by several kinds of positioning with grooves and protrusions provided by a pair of two-piece instruments, the adopter himself can use only one instrument. Can select the water flow rate and obtain the desired water saving rate.

EXAMPLE FIG. 1 is a vertical cross-sectional view of the product of the present invention.
(Hereinafter referred to as water) Water flows through the adjustment hole 5 for secondary water reduction and passes through the same adjustment hole 6 as it is to reduce the amount of water. Planned. FIG. 2 is a cross-sectional view showing the same state at the center of the concave-convex fitting portion, in which the protrusion 7 is formed in the groove 8-a for position setting.
FIG.

However, when the pressure and flow rate of water change and the user wants to save more water, the adjusting valve is taken out from the loading section, and the fastening screw bar 11 is first loosened several times and pushed in, and the two-divided concavo-convex fitting section is inserted. Of the adjustment hole 5 and the adjustment hole 6 shown in FIG. 3 when the protrusion 7 is removed from the adjustment positioning groove 8-a, turned slightly to the right and transferred to the groove 8-b and the screw rod is tightened back. The hole-shaped gap in the two-divided partition surface 3 became a water-passing hole as if the age was absent, and the cross-sectional area was clearly smaller than that at the position 8-a above, and the water saving rate could be increased.

For the same purpose, the projection 7 is formed in the groove 8-c.
The figure when changing the setting to is omitted, and the gap of the hole shape when set to 8-d becomes smaller and smaller, and the adjustment condition of the water saving amount was clear and the purpose could be selected.

In addition, in order to obtain a desired adjustment amount step, the water saving rate can be further improved by changing the adjustment hole 5, the adjustment hole 6, the inlet hole 12, the diameter of each hole, and the position of the positioning groove 8-abcd. I was able to enhance the change of.

[0010]

As described above, in adopting only one fluid passage amount adjusting valve of this type and loading it in the flow passage pipe,
Anyone can adopt normal householders and 雖, can be installed safely and easily without any special technology, and no matter who makes adjustments, they can choose their favorite water saving rate. Therefore, the purpose of saving water for all is easily reached. Now
It is said that CO2 emissions can be reduced by about 0.5 kg in saving 1 ton of water, which is an environmental issue that is being clamored for in the streets, and it has a significant contribution to that fact. I think so.
