The present invention relates to a detachable multifunctional water hammering prevention device.

In general, if the valve is closed rapidly when the fluid flows in the pipe line, the pressure in the pipe is rapidly increased to convert the kinetic energy of the fluid into pressure energy, which causes shock and noise in the pipe. This will happen.

In the prior art, in order to prevent the above water hammer phenomenon, as shown in FIG. 1, the cylinder 30 is integrally attached to the lower portion of the main body 40, and a spring ( A form in which a cylindrical stopper 52 is provided to prevent the piston 51 from being detached in a state where the 50 and the piston 51 are sequentially installed through the fluid passage 43 has been proposed. In addition, the reference numeral 53 is a sealing cap for connecting the water supply side piping line to the inlet side of the main body 40 through the O-ring 54. On the other hand, Figure 2 shows the water flow process in the conventional water hammer prevention device.

However, in the conventional water hammer prevention device, the stopper rotates together when the pipe is inserted into the main body, and the outlet opening of the stopper is rotated to block the inlet of the outlet, thereby reducing the flow of fluid.

When the spring lower bushing generates water hammer, especially when it is generated for a long time, the stopper is made of plastic and is exposed to hot water (water supply and hot water) for a long time and destroyed by fatigue accumulation, causing the spring to fall down due to the impact of the stopper. Water loss or blockage of the discharge port can make water supply impossible,

The stopper or bushing is fastened to the inside of the discharge port, which interrupts the flow of the fluid.

When the pipe is strongly inserted into the main body, the discharge port may be blocked by extending to the end beyond the entry prevention jaw of the plastic stopper, thereby preventing the flow of fluid.

The conventional water hammering prevention device has a problem in that a structure is complicated by including a stopper, which increases the work process and increases the cost of the product.

Therefore, the present invention is to provide a separate multifunctional water hammering prevention device that can simplify the work process as a simple structure and greatly reduce the product cost and at the same time effectively prevent the water hammer phenomenon.

The above object can be achieved by a detachable multifunctional water hammering prevention device manufactured according to the configuration described in the utility model registration claims of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in the removable multifunctional water hammering prevention device of the present invention.

Figure 3 is an exploded perspective view of the detachable multifunctional water hammering apparatus of the present invention.

As shown in FIG. 3, the detachable multifunctional water hammering prevention device according to the present invention includes a main body 11 connected to a pipe line and a cylinder 12 separated from the main body 11 and provided below. In addition, the cylinder 12 is provided with a piston 13 arranged to be able to move up and down inside the cylinder, a spring 15 for elastically supporting the piston 13 and a spring seat 14.

Above the main body 11, the inlet pipe connection part 16 and the outlet pipe connection part 17 which are connected with the fluid inlet lines are formed, respectively. The inlet pipe connection 16 is connected to the water supply side pipe line and the outlet pipe connection 17 is connected to the water valve side pipe line. As a result, when the water valve is opened, the tap water flows into the main body 11 through the inlet pipe connection part 16 and flows thereafter, and then discharges through the outlet pipe connection part 17. On the other hand, reference numeral 18 is a sealing cap for connecting the water supply side pipe line to the inlet pipe connecting portion 16 through the O-ring (19).

The outer circumference of the piston 13 is provided with an O-ring 20 to prevent tap water from entering the air chamber 21 side, the spring 15 buffers the piston 13 from the shock caused by the sudden operation of the water valve It is a coil spring which absorbs a shock and is provided in the cylinder 12. As shown in FIG.

As shown in FIG. 3, the cylinder 12 incorporating the piston 13 and the spring 15 is formed separately from the main body 11 and is fastened by screwing. The inside of the cylinder 12 is formed with an air chamber 21, the lower portion is closed.

As such, the main body 11 of the detachable multifunctional water hammering apparatus according to the present invention is not provided with a stopper as in the prior art apparatus. Thus, the stopper mounting engaging projection and guide groove in the prior art need not be formed inside the main body.

Therefore, the main body 11 of the detachable multifunctional water hammering apparatus according to the present invention is formed by processing a brass material in a press forging mold, and then smoothly manufactured by die casting, and a thread is formed by an automatic lathe inside to manufacture a simple and convenient process. Can be.

In addition, since the stopper is not provided, the work process can be simplified and the discharge port can be expanded. As a result, as well as smooth water flow, which is a problem in the prior art, the manufacturing cost is reduced by about 25%.

Figure 4 is a perspective view showing the assembled state of the detachable multifunctional water hammering apparatus according to the present invention. The detachable multifunctional water hammer prevention device inserts the piston 13, the spring 15, and the seat 14 into the air chamber 21 in the detachable cylinder 12, and then the sealing cap 18 and the O-ring 19 are mounted. By assembling by screwing the cylinder 12 to the main body 11, the assembling process can be performed quickly, stably and easily.

Figure 5 is a cross-sectional view showing a detachable multifunctional water hammering apparatus according to the present invention assembled as described above. As described above, the detachable multifunctional water hammering prevention device according to the present invention has a simple structure and can perform a stable water passage.

Figure 6 is a cross-sectional view illustrating a water flow process of the detachable multifunctional water hammering apparatus according to the present invention. As shown, the tap water is introduced into the main body 11 through the water supply side pipe line, and is continuously discharged through the through hole 22 to the outlet pipe connection portion 17 to supply the tap water to the outside. At this time, since there is no pressure change over the entire piping line, the piston 13 is located on the upper side of the air chamber 21 by the spring 15, and if the water valve is suddenly locked, the pressure change occurs over the piping line. As a result, pressure energy is generated in response to the pressure change, and the piston 13 is pushed downward to cushion the pressure change, thereby preventing damage to the pipe line.

In addition, as described above, the detachable multifunctional water hammering prevention device according to the present invention is smoothly processed through the passage of the tap water through the main body 11, there is no interference action such as a stopper, and smooth passage function by forming a large passage hole and outlet. Guaranteed.

On the other hand, the detachable multifunctional water hammering device according to the present invention may be used as a general connector by removing the cylinder 12 and its accessories from the main body 11 and closing the lower part of the main body with a cap when the water hammering prevention function is not required.

According to the detachable multifunctional water hammer prevention device according to the present invention, the simple structure without the stopper makes the work process complicated, the productivity is improved, and the cost can be reduced by about 25%, the stopper is free, and the flow of the tap water flow is reduced. It is not affected by the prevention, and the jaw of the stopper is clumped or blunted, so there is no fear of closing the discharge port, and the tap water passage hole can be formed larger, thereby providing a smooth and stable water flow. have.

In addition, according to the present invention, the detachable multifunctional water hammer prevention device can be used as a general connector by removing the detachable cylinder from the main body and closing the lower part of the main body with a cap. do.
