Description

Multifunctional water regulating instrument for tap water {Multifunctional water regulating instrument for water pipe}

The present invention is an improvement of the water-proof field used for tap water, and relates to a multifunctional water tap for water tap water having a backflow prevention function, a flow control function, an air discharge function in addition to the original water tap function.

The conventional water-functional multi-function water tap has a water stop chamber and a check valve chamber in the main body, and a ball cylinder with a part of an open side is accommodated in the water stop chamber, and the ball cylinder is rotated 90 ° from the outside. Can open and close the channel. In addition, the check valve chamber is provided with a check valve for applying a back pressing force by a spring and a valve stopper freely adjustable in position so as to prevent backflow and to regulate the valve opening amount at the time of daily water supply.

However, the following problems arise in such a conventional exponential warfare.

First, the valve body of the check valve is made of a copper alloy in the conventional index field. For this reason, the self-weight of the valve itself is so large that copper alloys come into contact with each other during the submersion, thereby increasing the frictional resistance during movement, slowing the operation of the valve, and smoothing the check operation. In addition, since the packing of the check valve is completely integrally attached to the valve body in the conventional water field warfare, if the packing is damaged, the entire valve must be replaced, which is expensive.

The present invention has been devised in view of the above problems, and an object of the present invention is to provide a multifunctional water stop for water that can perform the check valve lightly and quickly and surely. It is another object of the present invention to provide a multifunctional water stop for water supply which can be easily replaced with a new one when the packing of the check valve is freely replaced.

A main body having a water discharge chamber and a check valve chamber;

A ball cylinder in which the opening and closing operation is freely accommodated in the index chamber;

A check valve freely received in the check valve chamber;

A packing cover which serves as a cover of the check valve chamber;

It includes; a closing port for shielding the open end of the exhaust hole formed in the valve rod,

The check valve is made of synthetic resin, characterized in that the valve packing is detachably attached to the cross section of the check valve.

In the multifunctional index for water supply according to the present invention, the valve packing is annular and is inserted into the annular groove formed in the cross-section of the check valve, it is preferable that the pressure is fixed to the check valve by a packing support plate detachable.

Hereinafter, with reference to the accompanying drawings, an embodiment of the index before the present invention will be described.

As shown in FIG. 1, the water discharge chamber 2 and the check valve chamber 3 are formed in the cylindrical body 1. The ball cylinder 4 in which the side part which forms the water passage 5 is opened is accommodated in the still water front chamber 2 freely. At the lower end of the ball cylinder 4, a synthetic resin ball seat 6 is mounted. The lower ball seat 6 is equipped with a ball crimping hole 7 that is freely removable. The inlet 8 formed in the main body 1 communicates with the still water chamber 2. A water passage 9 is formed in the partition wall between the water discharge chamber 2 and the check valve chamber 3.

As shown in FIG. 2, the ball cylinder 4 may be rotated by the operation lever 10, and the opening / closing state is switched when rotated by 90 °. In the open state, the water flowing into the inlet (8) is introduced into the check valve chamber (3) through the water hole (5) of the ball cylinder (4) and the water hole (9) of the partition wall, and in the closed state the above-mentioned water communication Is blocked. In addition, the operation lever 10 can be freely attached and detached, and the lever can be removed to prevent theft of water.

The check valve 11 is accommodated freely in the check valve chamber 3 to move up and down. As shown in FIG. 3, the check valve 11 is a hollow cylinder with a closed bottom surface. In addition, the material is a synthetic resin, which is selected from polyoxymethylene (polyacetal) and the like, and has excellent water resistance and corrosion resistance, and does not adversely affect water quality even when aged. At the lower end of the check valve 11, a valve packing 12 made of synthetic rubber is attached. The valve packing 12 is annular, fits into the annular groove 13 formed on the bottom surface of the check valve 11, and is pressed upwardly by the packing support plate 14 to be fixed. The packing support plate 14 is freely screwed to the recess 15 of the check valve 11. Therefore, the valve packing 12 can be easily replaced by removing the packing support plate 14.

An elastic pressure is applied to the back surface of the check valve 11 by the spring 16, and the valve 11 is always pressed in the closing direction. However, the spring 16 has a weak elastic force, when the ball body is in the open state, the valve 11 is raised by the water pressure of water, and water flows into the check valve chamber 3 through the water inlet 9. . 17 is a packing cover which also serves as a cover of the check valve chamber 3, and is screwed and fixed to the main body 1. The lower inner surface of the packing cover 17 serves as an inner surface for the rest of the year when the check valve 3 moves up and down.

The valve rod 18 is rotatably mounted through the packing cover 17. A lower portion of the valve rod 18 is a screw portion, and a valve stopper 20 is spirally coupled to the screw portion. Therefore, when the valve rod 18 is rotated using the handle 21, the valve stopper 20 moves up and down. Moreover, the protrusion formed in the side surface of the valve stopper 20 is engaged with the vertical groove formed in the inner surface of the packing cover 17, so that the valve stopper 20 can move up and down, but cannot rotate.

The check valve 11 collides with the valve stopper 20 when lifted by hydraulic pressure. Therefore, by adjusting the up-down position of the valve stopper 20, the uppermost position of the check valve 11 can be regulated, and the amount of water flow can be adjusted. In addition, since the cushioning material made of an elastic material is attached to the lower surface of the flange portion of the valve stopper 20, it is possible to alleviate the shock when the valve collides.

The valve rod 18 is formed with an exhaust hole 23 passing through the central portion thereof. 24 is a closure that is attached to the top opening of the exhaust hole. Therefore, when the closing opening 24 is removed, the air can be discharged from the inside of the check valve chamber 3 to the outside. The exhaust operation is used to discharge the air remaining in the pipeline or outside the pipeline after piping work to the outside. In addition, a pressure gauge may be attached to the exhaust hole 23 and used to measure the water pressure in the pipeline.

The outlet port 25 of the main body 1 communicates with the check valve chamber 3, and the expansion joint 26 is attached to the outlet port 25. As shown in FIG. 1, the expansion joint 26 is composed of a short pipe 27, a thrust packing 28, a fixing cap nut 29, and a pipe connection cap nut 30 for free movement.

Next, the operation before the exponent will be described.

When the ball cylinder 4 is in the open position, water coming from the inlet 8 reaches the water passage 9 through the water passage 5 of the main body. The water inlet 9 is always closed by the check valve 11, but since the elastic force of the spring 16 acting on the back surface of the valve body is weak, when the check valve 11 rises due to water pressure, the water flows into the check valve chamber. (3) flows into the interior and enters the outlet 25.

In addition, when the inflow of water stops and a back flow occurs, the check valve 11 is contacted with the water inlet 9 by the pressure of the spring 16 to close the water inlet, thereby preventing backflow. Since the check valve 11 is made of synthetic resin, it is light, and since the contact between the synthetic resin and the copper alloy occurs in the inside of the packing cover 17 made of copper alloy, the frictional resistance is reduced, compared to the case of the conventional copper alloy alone. The operation at the time of operation is not only quick, but also unaffected by its own weight, and the check operation is performed reliably and quickly regardless of the contact angle. In addition, when the valve packing 12 is damaged, the packing support plate 14 can be removed and replaced with a new one.

In addition, the opening amount which is the raising amount of the check valve 11 at the time of water passage can be adjusted by rotating the handle 21 and raising and lowering the position of the valve stopper 20. Therefore, the amount of water flow can be freely adjusted in response to the height of the water pressure in the tap water. And when the operating lever 10 is rotated 90 degrees, the channel can be opened and closed. Therefore, the water passage can be stopped and the valve packing 12 or the like can be easily replaced. In addition, since the check valve chamber 3 communicates with the outside when the closing port 24 is removed, the air can be easily discharged from the valve chamber interior or the conduit.

The present invention is not limited to the above embodiments and can be modified freely within the scope of the claims. In particular, the shape of the check valve 11 and the type of synthetic resin as the material, the material and shape of the valve packing 12, the attachment type to the check valve 11, and the like are free.

In addition to the opening / closing function of the water passage, the still water field according to the present invention has a backflow prevention function, a flow control function, an air discharge function, and the like and can fully and reliably exhibit these functions. In addition, according to the exponent according to the present invention, the check valve is made of synthetic resin, which is lighter than the case of the conventional copper alloy alone, and also has a low frictional resistance on the inner surface during the revolution, so that the operation during the check operation is quick, In addition to being able to prevent backflow quickly, the check function can be reliably performed at any contact angle. In addition, according to the present invention, since the valve packing becomes detachable and self-sustaining with respect to the check valve and can be simply replaced with a new one when damaged, it is more economical than the method of replacing the check valve as a whole as in the prior art.

And, as in claim 2, since the packing can be replaced by removing the packing support plate, the packing replacement operation can be performed simply and quickly.
