Description

Valve for water supply

The present invention is a devise related to a water supply shutoff valve interposed between pipes of water supply to block water supply, and more particularly, to provide a structure that prevents water leakage, which is a problem of the conventional shutoff valve, so that a complete blockage can be maintained for a long time. It is devising about things.

The water supply pipe consists of pipes of various standards buried underground to supply purified tap water.It is not common to supply natural water depending on the altitude of the supply site, so it is customary to supply water pressure above a certain pressure. In the water supply facility, the high pressure pump is installed in order to apply a large pressure, so a large pressure is applied to the water supply. Therefore, the pipe is supplied with a pressure higher than atmospheric pressure to supply water.

Therefore, in order to shut off the water supply due to a breakdown of the equipment in the water supply facility or any other cause, the valve must be shut off under a pressure greater than that for the drainage valve, thereby increasing the size and precision of the valve. Therefore, the valve is also located in the basement is difficult to install and replace, and therefore, once installed, it is preferable to be used for a long time, it is a situation that it is important to maintain durability at all times while being precisely sealed under high pressure.

By the way, the most commonly used among these shut-off valves is a conduit (23, 23) extending to both sides, as shown in Figure 5, and a plurality of bolt holes (25) at the end of each conduit (23) The perforated flange 24 formed integrally, the top cover 22 for sealing the upper portion of the body and the top cover 21 for sealing the upper opening of the top cover of the conduits (23, 23) of both sides A valve case 2 accommodating both ends therein; The upper end is provided with a handle key 11 is inserted into the handle, the operating period (1) extending through the center of the upper cover 21 of the valve case (2) into the valve case (2); And a blocking part 3 installed in the valve case 2 and having a blocking wall 31 for controlling water supply according to the operation of the operation 1.

The above-mentioned shut-off valve is interposed in the middle of the medium-large water supply pipe 6, and since the pipes 6 and 6 on both sides form the same pipe flange 61 as the flange 24, they face each other. After the rubber ring 26 is interposed, the bolt 5 is fastened through the bolt hole 25 to secure the connection and the sealing at the same time. 3) The blocking wall 31 comes down, and the conduits 23 and 23 on both sides accommodated in the valve case 2 are spaced apart from each other while the upper side is slightly wider than the lower side, and the blocking wall 31 is also the same. When the barrier wall 31 is tapered at an inclined angle, both sides of the barrier wall 31 seal the conduits 23 and 23 on both sides, respectively, so that the water supply is cut off. Reverse the direction and lift the blocking wall 31 The valve opens to allow water flow.

However, the above-described conventional design has a problem, that is, the gap between the conduits 23 and 23 facing each other in the valve case 2 and the blocking wall 31 are tapered in the upper part so that water is easily blocked / Opening is made, but the bottom wall of the valve case 2 is expanded downward to receive the bottom of the blocking wall 31 because the sealing wall 31 is completely closed at a position slightly lower than the bottom of the conduit 23. If dirt or foreign substances (hereinafter referred to as 'precipitates') mixed in the water supply and settled in the gaps between the conduits 23 and 23 are blocked, the lowering of the barrier wall 31 prevents the water from being completely blocked. In addition, these deposits (S) also wears the lower end of the barrier wall 31 to create a gap, and thus there is a problem that incomplete blocking of water supply due to construction or an accident causes problems in solving these causes.

The present invention has been completed as a result of careful attention to the above problems over a long period of time, and efforts to improve the problem, to provide a structure that does not occur even if foreign matter or sediment is introduced into the valve to achieve a complete water supply / cut off, and While using the conventional valve as it is to solve such a problem, in particular to solve the problem is made to be made easily and economically, it will be described in detail below with reference to the drawings.

The present invention, as shown in the drawings, the conduit (23, 23) extending to both sides, the flange 24 formed integrally by drilling a plurality of bolt holes 25 at the end of each of the conduit (23), A valve case (2) for receiving both ends of the conduits (23, 23) inside the upper cover (22) for sealing the upper part of the main body and the upper cover (21) for sealing the upper opening of the upper cover; The upper end is provided with a handle key 11 is inserted into the handle, the operating period (1) extending through the center of the upper cover 21 of the valve case (2) into the valve case (2); Guide guides 32 and 32 are formed between the guide protrusions 32 and 32 formed on both sides of the inner circumferential wall of the valve case 2 and both conduits 23 and 23 accommodated in the valve case 2. In the shutoff valve consisting of;

The taper pads 41 having the same shape as the inner space between the two conduits 23 and 23 in the valve case 2 and the lower ends of the valve cases 2 and the inner diameters of the lower ends of the two conduits 23 and 23 are formed. Characterized in that it is received at a matching height.

Figure 4b is a state diagram shown in cross-section to easily understand the blocking state of the present invention.

In the above configuration, it is preferable that at least one spring 42 is embedded in the tapered pad 41 at the position at which the blocking wall 31 is pressed.

Looking at the effect of the present invention configured as described above with reference to the drawings as follows.

Figure 4 is a cross-sectional view showing the operating state between the blocking wall 31 and the taper pad 41, which is the main part of the present invention, a is a block diagram showing a state of passage b just before being blocked. to be.

In the water supply shutoff valve of the present invention, since the pipes 6 and 6 on both sides form the same pipe flange 61 as the flange 24, the pipes 61 are faced to each other and the rubber ring 26 is interposed therebetween { It is desirable to form the insertion recess and insert the rubber ring 26 into the same as in the water shutoff valve of Utility Model Registration No. 224565, which is hard by tightening the bolt 5 through the bolt hole 25. At the same time as the connection to achieve a seal, after the installation is turned so as to turn off the operation (1) to cut off the blocking wall (31) of the blocking portion (3) comes down the guide projections (32, 32), the valve case (2 The conduits 23 and 23 accommodated in the two sides are spaced apart from each other and spaced slightly above the bottom (an inclination angle of about 3 °), and the blocking wall 31 is also tapered at the same inclination angle so that the blocking wall 31 Car) in the state The gap between the both sides of the wall 31 and the ends of the conduits (23, 23) on both sides is generated a gap (Gap) can be supplied to the water supply, but when the blocking wall 31 is a predetermined distance down the blocking wall Both sides of the (31) seal the conduits (23, 23) on both sides, respectively, so that the water supply is blocked (in this case, it is common to cover the both sides of the barrier wall 31 with a lever or Teflon to improve the sealing force), When re-supplying water, the valve is opened to allow water to flow when the blocking wall 31 is lifted by turning the operation 2 reversely, which is the same as the conventional shut-off valve.

However, in addition to the above-described configuration, the water supply shutoff valve of the present invention has a taper pad having the same shape as that of the inner space formed by the gap between the two conduits 23 and 23 in the valve case 2 and the lower end of the valve case 2. Since 41 is accommodated at a height that matches the inner diameter of the lower ends of the both conduits 23 and 23, the taper pad 41 is provided with the inner diameters of the lower ends of the both conduits 23 and 23 in the valve case 2. Sediment (S) to be fed and mixed in the water supply by having a matching height is not accumulated at the bottom of the valve case (2) is to be supplied as it is, at this time, the blocking wall 31 is lowered to the lower part of the lower conduit (23) , 23, even if the lower portion of the lower end of the tapered pad 41 is made of soft rubber or resin, while being pressed down does not significantly affect the lowering of the blocking wall 31 is completely blocked the water supply G When the water flows again by advancing the blocking wall again, the taper pad 41 is restored and again coincides with the inner diameter of the lower ends of both conduits 23 and 23 without a step so that the sediment S is not accumulated and is permanently supplied with water. Enables blocking / passing of

In addition to the above configuration, in the dependent claims of the present invention, one or more springs 42 are embedded in the tapered pad 41 at a position at which the barrier wall 31 is pressed, and the springs 42 are tapered. By improving the restoring force of the pad 41, the taper pad 41 may be matched with the outer diameters of the lower ends of both conduits 23 and 23 for a longer period of time, thereby improving durability. If the constant is too large, it is easy to be separated from the material forming the taper pad 41 when the taper pad 41 is pressed and compressed while disturbing the lower side of the blocking wall 31. It is preferable to use two or more thereof according to the modulus of elasticity.

As described above, the present invention provides a structure in which precipitation does not occur even when foreign substances or sediments are introduced into the valve to achieve complete water supply / blocking, and to solve these problems while using the conventional valve as it is, in particular, It is an effective and useful design designed to be solved easily and economically.
