Abstract

PROBLEM TO BE SOLVED: To effectively reduce an instant high pressure shock in a water supplying pipe, suppress hummer action, and prevent breakage of the pipe by engaging a clutch gear and a normal position gear with a bush rod, and separating steps and normally positioning a pressure control unit so as to stop water by a vertical operation. SOLUTION: In the case where a shower head is used, when a push button 51 is pushed down by a user, a crank shaped connecting tool 55 is pushed, and a bush rod 25 of a step separating control part 2 is push-pressed. In this time, a clutch gear 22 and a normal position gear 23 are engaged with each other, a plug part 113 is opened, and water is discharged. After that, when the push button 51 is pushed again, engagement of the normal position gear 23 with the clutch gear 22 is released, pressure eliminating seat 11 is operated. After that, an opening end of a gear seat 21 is pushed by the plug part 113, and its opening end is closed. A part of water gradually flows into the gear seat 21 through a depressurizing hole 110. It is thus possible to avoid to rapidly close the plug part 113, and it is also possible to prevent generation of water hummer phenomenon.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a valve structure provided with a decompression and decompression control means, and more particularly to a decompression seat, a decompression valve, and an engagement for opening and closing a water flow by using an instantaneous water pressure by a water hammer action. The present invention relates to a structure for controlling a stage by the action of a tool and a stage control unit, thereby effectively controlling an instantaneous high-pressure impact in a pipe and avoiding a rupture of the pipe.

[0002]

2. Description of the Related Art In general, a water supply pipe of a high-rise building is generally designed so that a pipe diameter of a water discharge pipe is smaller than a pipe diameter of a main water supply pipe in order to prevent the pipe from being ruptured due to a water hammer phenomenon at an instantaneous interruption of water flow. It is also designed to be small. However, this design has the disadvantage that the rupture of the pipe cannot be completely prevented and the construction is difficult. Therefore, various decompression and decompression devices have appeared.
However, among the currently known decompression and decompression devices, there is no device that simultaneously has decompression and decompression functions and that controls the water flow or any other fluid in stages. Must be procured and separately assembled for use. This can happen to manufacturers, sellers,
And it is very inconvenient for three users.

In view of the above-mentioned drawbacks of the conventional decompression device, the present inventor has conducted research on these drawbacks, made improvements, and finally produced the present invention.

FIGS. 3A, 3B, 3C, 3D and 3E
It is a figure showing operation of an embodiment of pressure control part 1 and division control part 2 of the present invention. As can be seen from these figures and the embodiments of FIGS. 1 and 4, when the user presses the push button 51 of the holding control unit 5 lightly, the bush rod 54 acts on the joint 55 and the joint 55 Operate. By the operation of the connecting member 55, the bush rod 25 of the division control unit 2 is pushed forward, and is engaged with the clutch gear 22 and the localization gear 23 that are closely joined to the end of the bush rod 25 to operate. From the closed state shown in FIG. 3B, the state changes to the open state shown in FIG. 3B. At that time, as shown in FIG. 3C, the pressure control unit 1 engages with the clutch gear unit 212 by the action of the localization gear 23 of the division control unit 2 to localize, thereby removing the water flow. As shown by the arrow outside the pressure seat 11, the water flows out from the water discharge body 4 via the internal space of the gear seat 21.

When the push button 51 is lightly pressed again, the division control unit 2 is pushed forward, and the localization gear 23 and the clutch gear unit 2 are pushed.

The end is pressed and the opening of the gear seat 21 is closed. Due to this instantaneous water cutoff operation, a water hammer phenomenon occurs due to the water flow in the pipe, and the pressure reducing valve 12
However, due to the large instantaneous hydraulic pressure thrust generated when the water was cut off,
As indicated by the arrow E, a small amount of water flows into the space inside the gear seat 21 gradually in a small amount via the space inside the pressure reduction seat 11 and the pressure reduction hole 110. After a considerable time, when the instantaneous water pressure due to the interruption of the water supply outside the decompression seat 11 gradually decreases to the elasticity of the spring 14 of the pressure control unit, the spring 14 presses the decompression valve 12 downward and engages. The launch hole 131 of the tool 13 is closed, and the water flow is completely shut off. At that time, the water pressure in the pipe reaches an appropriate equilibrium. In this way, pipe rupture due to the impact action of high water pressure is prevented.

As can be seen with reference to FIG. 4 together with the drawing, when the push button 51 is lightly pressed, the push button 51 pushes the bush rod 54 having the water stop gasket 53 through the fitting 52, and the push button 51 enters the inside of the water discharge body 4. Acting on the provided joint 55, the joint 5
By the operation of 5, the bush rod of the division control unit 2 is operated downward, and the opening and closing of the decompression seat 11 and the opening of the gear seat 21 of the pressure control unit 1 are controlled to achieve water flow control. .
