Description

Faucet tightening tee fittings manufacturing method

Faucets or appliances in the building where people live should always be supplied with adequate water pressure and flow rate in order to fully function according to the purpose of use, and designers and builders will always make an effort for such piping system.

Faucet or equipment supplies water to and shuts off by operating the shut-off valve, and after closing the valve of the faucet, the water flowing in the pipe suddenly changes the speed of water due to the suddenly blocked wall, causing severe pressure change. Done. Such pressure waves of water are transmitted to faucets, appliances, and surrounding pipe walls, causing loud noises and vibrations.

This is called water hammer, and the kinetic energy of the fluid changes to pressure energy, causing high pressure waves from the breaking point to reciprocate between the points where the pipes collide to the main or granular pipes with large diameters until the pressure shock waves disappear. do.

This causes noise and vibration, breaks down pipes and joints, loosens hangs and supports by high pressure waves, and damages valves, meters, and equipment prematurely, causing enormous economic losses.

According to Joukowsky's formula in 1898, the closing time of sanitary appliances Pr = second (kgs / cm ² ) When the pressure is 1.5m / s to 3.0m / s, the pressure is about 14 times higher than the fluid velocity. 20 kg / cm ^{2 to} 40 kg / cm ² Pressure wave propagation speed is 1,200 ~ 1,500m / s.

Although the cause of water hammer action has been identified scientifically, the prevention method is also theorized, but the building is getting higher and larger, and pump pressure type or pressure tank type of water supply method means high water supply pressure and speed. Due to the electric solenoid valves and the like, it is causing much more severe water hammer action.

Although there is no fundamentally complete countermeasure against water hammer, we have been aware of this phenomenon in the past and have used several shock absorbing solutions as solutions. Firstly, the same caliber upwards or larger than the faucet fitting connecting the faucet or equipment. There is a way to make an air bag by blocking the upper part of the tube by extending 30cm ~ 60cm.

It uses the compressibility of the gas. When the water of impact pressure pushes the air layer of the air bag, it compresses and acts as a shock absorber. The disadvantage of this method is that it does not last long while the shock pressure is generated and water is absorbed into the air bag. It is lost.

In order to continue to perform in this way, air must be frequently charged and a valve cock, etc., capable of recharging the air must be installed at the end of the tube with an air bag, but the fittings for connecting the faucet are 15A, 20, 25 The engineering faucet is buried in the wall by concrete or mortar, making it impossible to install a valve cock.

Secondly, the engineered absorber contains water contact and gas chambers such as air or nitrogen, separated by rubber membranes or ball-filled bellows, which is Boyle's law. ₁ · V ₁ = P ₂ · V ₂ = Absorption of impact pressure by a constant equation.

This type of absorber has the disadvantage of requiring frequent repairs due to the limited flexibility and short life of the rubber membrane and the absorber's container as a vertical tank, so the absorber can be installed in the middle of a water supply line with a separate large place or space. There is no choice but to.

More recent shock absorbers include pistons that completely separate high pressure air or pressure gas chambers and water contact chambers by pistons.

The absorber is somewhat superior in lifespan and function, but due to its high cost and economical diameter, the tube has a diameter larger than the diameter of the faucet fitting connected to the faucet, and thus requires a separate installation space.

All the above engineering shock absorbers or shock absorbers are installed in the field where piping is installed, which adds construction costs and is supplied as a standalone product, which requires additional pipe fittings and accessories depending on the connection method. There is this.

The water supply system in the building is water supply type, high water tank type, pressure tank or pressurization method by pump, and the water supply method is selected according to the size, structure, and use of the building. Will be sent.

In order to obtain proper water supply and diameter, the instrument water supply unit, instrument usage prediction method, simultaneous utilization rate, pipe friction resistance diagram, pipe uniformity table, etc. are used. National engineers use almost uniformly.

However, even if the piping is done in this way, there is a difference in water pressure and flow rate in each faucet or equipment.

At the height of the building, that is, the lower and higher parts, the water supply pressure and the flow rate are different due to the static pressure difference caused by gravity or the pressure loss caused by frictional resistance.

In the water supply system, the common faucet is 0.3kgs / cm ^{2 and the} mixed faucet is 0.5kgs / cm ^{2 and the} toilet is 0.7kgs / cm ^{2 and the} shower is 0.8kgs / cm ² . Water supply pressure is limited to 2kgs / cm ² single-family houses, hospitals and hospitals, and ³ ~ 4kgs / cm ² general buildings to 4-5kgs / cm ² or less. Each faucet has an unbalanced flow system. It is operated by.

As a result, water is generated from the faucet with a water supply pressure exceeding a certain range or more, and the higher the water supply pressure, the larger the pressure fluctuation range depending on whether the faucet is used at the same time.

In order to adjust the water supply, the user must operate the switch of the faucet, but it is not easy, and in particular, it is almost impossible to adjust the flow rate in the touch or automatic faucet supplied in recent years.

The pressure and flow rate of the water supply pipe can be adjusted by installing a pressure reducing valve or a flow control valve.However, such a control valve is not installed at the end of a faucet or the like. The flow rate of each faucet cannot be constant because it is installed in the area such as larger pipe stem.

To solve the above problems, the present inventors Magnetic pipe fittings with the invention patent No. 14605 (98.04.24) Magnetic fittings have been filed in Utility Model No. 11925 (98.07.01).

However, in the above application, since the fixed blades formed at the upper end and the lower end of the water supply tube are independent structures outside the water supply tube, the water supply tube is moved while the fixed wing is deformed in the process of repeated shocks or compression movement of the pressure wave. If it is severe, there is a drawback of deviation The granular rubber filled with the shock absorbing device of the magnetic fitting is inserted between the spring intervals when the compression spring is compressed, and the spring line of the compression spring is deformed. There is a downside to falling.

Also The compression spring structure, which is a composite of the compression spring and the rubber elastic body, is housed in the outer space of the water supply tube composed of the shock absorbing device of the magnetic pipe fitting. The compression spring and the rubber elastic body are separated, and the separated rubber elastic body interferes with the compression movement of the compression spring, thereby lowering the shock absorbing ability and causing wear of the rubber elastic body.

Therefore, the present invention has been proposed to solve the above problems, and its purpose is to use a shock absorber and a flow control device in parallel with a T-shaped fitting connecting a faucet or equipment. It is to provide a faucet fastening T-shape fittings that can absorb water and mitigate the water hammer action to prevent noise and vibration, and to control water supply.

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

1 is a view showing an embodiment of a faucet fastening T-shaped fittings having a shock absorbing device and a flow control device according to the present invention in the drawing, the reference numeral 1 in the figure is a body used to fasten the faucet or equipment. Metal T-shaped fittings.

On the inner circumferential surface of the protruding body of the T-shaped pipe fitting 1, a tapered female screw 2 made of a conventional screw is formed to fasten with a screw formed in a faucet or a device.

The upper body and the lower body of the T-shaped fitting (1) is a device for absorbing the shock is accommodated.

In order to achieve the above object, the inner circumferential surface of the upper body of the T-shaped fitting (1) of the present invention is located at the lower end of the inner diameter and is horizontally positioned at the upper surface of the protruding female screw (2). Will form.

Since the upper annulus 3 is formed with a diameter smaller than the inner diameter of the upper body of the T-shaped fitting 1, the function of supporting the shock absorber assembly accommodated in the upper body will be described below. By defining the diameter cross-sectional area of the directional ring (3), it is used as a standard for setting the allowable load of the compressed rubber elastic body (9) incorporating the stainless steel compression spring (8a) with the allowable load as a shock absorbing device. .

Stainless steel washer 4 as shown in Figure 2 of the assembly of the shock absorbing device accommodated in the upper body inner diameter space portion has an outer diameter of about 0.05 to 0.5mm less than the inner diameter of the upper body, Metal rods 5 larger than about 0.05 to 0.1 mm are formed rather than the stainless steel rods 7 to be described in the above, and are responsible for directly receiving the shear pressure of the shock wave generated by closing the valve of the faucet. The same stainless steel support washer 6 has a shape in which a stainless rod 7 which is about 3 to 10 mm longer than the length of the upper portion of the T-shaped fitting 1 in the body is fixed.

The compressed rubber elastic body 9 inserted into the stainless steel rod 7 is a foamed molded product, which is responsible for absorbing and mitigating shock while compressing at a shear pressure of a shock wave, and storing water having an elevated pressure. .

The compressed rubber elastic body 9 has a structure in which a stainless steel compression spring 8a is built in the body as shown in FIG. 4 and has an outer diameter of about 1.0 to 3.0 mm smaller than the inner diameter of the upper body and a metal rod at the center of the body. 5) is formed and composed of an independent body divided into 2 to 5 on the basis of the upper body length is inserted into the stainless steel rod (7).

The compressed rubber elastomer 9 includes the allowable load of the built-in stainless steel compression spring 8a, and the allowable load of the total length of the compressed rubber elastomer 9 accommodated, regardless of the number of individual entities divided into it, is different. If it is installed in the directional body space, it is formed into a structure having an initial compressive tension of 4 to 10 kg / cm ^{2 and} a high allowable compressive load strength.

Since the stainless steel washer 4 is inserted between each of the divided compressed rubber elastomers 9 fitted to the stainless steel rods 7, the compressed rubber elastic bodies 9 may occur while repeating the compression and restoration movement by the shock wave. When eccentric deformation due to deviating phenomenon, buckling and eccentric stress is prevented and the compressed rubber elastic body (9), which is divided into two or five, is accommodated as an integral long rubber elastic body, the density of rubber elastic body becomes dense during compression movement. This is because the parts are severely swollen and protruded, causing friction with the body part, thereby reducing the life of the compressed rubber elastic body 9 due to wear or breakage.

Due to the volume of the compressed rubber elastomer 9, the inner space of the upper body has a very small residual area, which minimizes the water flowing into the upper body gap during compression and restoration, thereby increasing the effect of absorbing shock and increasing the shock absorbing capacity. To keep.

The shock absorber assembly assembled with the above-described structure is inserted into the T-shaped pipe fitting (1) in the upper body space to accommodate the seal and then the end of the body is closed by the cap (10).

The T-shaped pipe fitting (1) is formed at the upper end of the inner circumferential surface of the lower body is formed with a lower downhole (11) larger than the outer diameter of the water supply tube (12) tubing described below and less than the outer diameter of the flanges (13, 14) As a result, a function of introducing a pressure wave generated while closing the valve into the storage port 16 provided in the upper flange 13 of the feed tube 12 is provided.

The water supply tube 12 as shown in Fig. 5 to accommodate the T-shaped pipe fitting (1) in the downward body has the same inner diameter as the water supply pipe leading from the pipe and has a length of about 4 to 10 cm in length and The same upper flange 13 and the lower flange 14 as shown in Figure 7 are formed at both ends, and inserted into the body of the T-shaped fittings 1 so that it is fixed in close contact with the downward annular opening 11 In the outer diameter of the body of the tube 12, the flanges 13 and 14 at both ends can be fixed to the center of the inner diameter of the T-shaped fitting 1 while forming the front chamber 15 which is an environmental space portion between the outer diameters.

The upper flange 13 formed at the upper end of the water supply tube 12 is formed in the receiving opening 16 is divided into a plurality of receiving water of the pressure wave as shown in Figure 6 and the lower flange 14 of the lower end 7 is the same as the plurality of divided discharge port 17 is formed and the lower flange 14 is formed by a protrusion bar 18 protruding about 1.0 to 5.0mm of the number of equal short in the bottom surface outward direction. .

The plurality of protruding rods 18 may have a length corresponding to the length of the protruding rods 18 protruding when the orifice bushing 22, which will be described below, is in close contact with the lower flange 14 of the feed tube 12. This is to allow the entire circumference to have a gap 19 at intervals.

The front chamber 15 formed in the water supply tube 12 has an inner diameter of 0.04 to 0.2 mm larger than the outer diameter of the tubular body of the water supply tube 12, and an inner diameter of 0.04 to 0.2 mm smaller than the outer diameter of the flanges 13 and 14 at both ends. The storage washer 20 which can be freely moved in the air is responsible for receiving the pressure wave flowing into the lower annular opening 11 and the receiving opening 16, and is supported by the storage washer 20 again to supply the water supply tube 12. It has an allowable compressive strength, such as the length of), and the assembly is performed by inserting a stainless compression spring (21b) that absorbs and mitigates shock while compressing according to the shear strength of the pressure wave.

Insert the water supply tube (12) assembly into the lower body of the T-shaped fitting (1) body so that the upper flange (13) is in close contact with the lower annular opening (11) and the orifice bushing (22) again the water supply tube ( 12), the fixing rod 18 is formed on the lower flange 15 of the water supply tube 12 so that both sides 14 and 22 form a gap 19, and the water supply tube 12 is It will be fixed.

When explaining the operation principle of the shock absorber

1) If not using faucet

Since the inner diameter of the water supply tube 12 is filled with water of positive pressure due to the height and density of the fluid at the place where the faucet or equipment is located, the front chamber 15 of the water supply tube 12 also passes through the gap 19 and the drain hole 17 Due to the water flowing into), the space portion excluding the total area of the stainless steel compression spring 21b accommodated into the front chamber 15 is filled with water according to Pascal's principle.

In general, since the water supply pressure of the head of water faucet, which is designed or constructed, is constructed at about ⁴ to 5 kgs / cm ² or less, the water introduced into the front chamber 15 is filled with water of the same pressure. At this time, the stainless steel compression spring 21b is prescribed. Since it has a load strength of, the initial shape is maintained without compressive movement in the constant pressure water supply with the washer 20.

In addition, the impact absorbing device of the upward body also has an initial tension of ⁴ to 10 kgs / cm ² , although a small amount of water flows in a small space except the volume of the compressed rubber elastomer 9. The stainless steel washer (4) together to maintain the initial shape without the compression movement.

2) When using a faucet

According to Tori Cherry's theorem, the water in the water supply pipe flows out into the faucet which is opened under constant pressure and dynamic pressure, but the water that flows into the front chamber 15 of the water supply tube 12 is the inner diameter of the pipe body through which the front chamber 15 is supplied with water. Independent of the pipeline, the water flowing into the front chamber 15 can be stored in the initial state at the time of constant pressure without using a faucet.

3) When the faucet is closed

The water flowing due to the suddenly clogged wall generates a high shock wave from the breaking point as the kinetic energy is changed to the pressure energy, which is then transmitted to the stainless steel washer 4, which is the shock absorber of the upward body. Due to this, the compressive rubber elastic body 9 having the specified load strength is absorbed and absorbed by the shearing strength of the shock wave, and absorbs water into the space formed by the compression movement.

On the other hand, some of the pressure wave propagates through the inner diameter of the water supply tube 12 to the water supply tube in the retreat wave phenomenon, and some of the pressure wave is pushed to the downward round hole (11) of the T-shaped fitting (1) It works.

When the inner diameter cross-sectional area of the feed tube 12 is set to 1, the cross-sectional area of the front chamber 15 used in the present invention is 0.7 to 1.5, so that the cross-sectional area of the drainage tube 12 is about 0.7 to 1.5. Coming pressure wave immediately pushes the storage washer 20 which is blocking the storage port 16 past the storage port 16 of the upper flange 13 and changes into a sudden expansion tube structure of 1.7 to 2.5 times, which is a fluid momentum equation and a Bernoulli equation. It is accompanied by the energy loss by the retreat wave strength propagated in the inner diameter direction of the feed tube 13 can be greatly reduced.

The pressure wave pushed into the downward annular opening 11 passes through the receiving opening 16 of the upper flange 13 of the water supply tube 12 through the downward annular opening 11 and the pressure of the shear force on the storage washer 20. While acting as a stainless steel compression spring (21b) is a compression movement to the specified allowable load to work to absorb the shock wave. At the same time, the shock wave flows into the space portion of the front chamber 15 formed by the storage washer 20 that moves backward.

Meanwhile, the water in the front chamber 15 staying at a constant pressure is pushed downward due to the storage washer 20 that is retracted, and formed in the lower flange 15 of the water supply tube 12 to pass through the sediment outlet 17. After it is returned to the water supply tube 12 through the gap 19, and this work is repeated every time the shock absorbing movement.

4) After closing the faucet, after a certain time

The water flowing into the upper body of the T-shaped pipe fitting (1) passes over time, and when the water in the water supply pipe returns to normal normal pressure, the water introduced by the elastic restoring force of the compressed rubber elastomer (9) is pushed out. The body is returned to the body, and the stainless steel compression spring 21b in the front chamber 15 of the feed tube 12 is also restored to its initial state by the elastic restoring force. This is repeated every time the faucet is used.

The orifice bushing 22 as shown in FIG. 8 inserted into the lower body of the T-shaped fitting 1 and in close contact with the lower flange 14 of the feed tube 12 has a T-shaped fitting 1. Orifice fastening screw portion 24 is formed on the inner circumferential surface to fix or bond with welding or adhesive. The fixed orifice bushing 22 is designed to prevent the water supply tube 12 from moving under pressure shock or vibration. At the same time plays a role and has the function of adjusting the flow rate with the means for forming the gap 19 described above.

The orifice bushing 22 is made of an orifice 23 having the same inner diameter as the inner diameter cross-sectional area of the water supply pipe or the water supply tube 12 or a smaller number of inner diameters in proportion to the hydrostatic head pressure in the water supply pipe. .

The orifice bushing 22 has a different amount of water discharged to the faucet due to the static pressure difference due to the height of the building, that is, the height and density of the fluid. Water supply balancing and reducing waste of water by piping to the T-shaped pipe fitting (1) with the orifice bushing (22) in which the orifice (23) formed in proportion to the low-floor part with high static pressure calculated as I will.

The T-shaped pipe fitting (1) has a male thread (25) which is connected to the water supply pipe at the lower end of the body. However, since the pipe connection method is different for each pipe type, the lower body has a lower end. It can have a connection port such as female thread, insert welding type, and the like, as shown in FIG. 10, after forming the adapter fastening screw portion 27 at the inner circumferential surface of the T-shaped fitting (1), as shown in FIG. (26), the insert welding fastener 29, the adapter 26, the pipe fastener type 30 to be used by connecting the metal pipe 31, the adapter 26, or the adapter 26 fastened by a plastic pipe or the like. Separately manufactured and used in conjunction with the adapter fastening screw portion 27 formed in the T-shaped fitting (1).

The T-shaped fitting 1 is a faucet for use at a low static pressure, that is, at a terminal static pressure head having a static pressure in the tube of 2.0 to 2.5 kg / cm ² or less, or a shock wave causing a water hammer in a slow piping system, Since the shock absorbing device, which is a component of the water supply tube 12 of the downward body as shown in FIG. 11, is omitted, the economical faucet fastening T-shaped pipe fitting formed solely of the shock absorbing device configured on the upper body is formed. Will be

In addition, the metal T-shaped fittings (1) is to reduce the production cost, the purpose of reducing the load of the material installed in the building and unlike metal, unlike the material does not cause corrosion by water as shown in Figure 12 It is also manufactured by the T-shaped fittings 32 of the plastic body.

The plastic T-shaped pipe fitting 32 is a metal pipe body of the faucet currently being used, and the water pipe is also made of metal, so if the screw is fastened by forming a screw in the plastic body due to the difference in the coefficient of thermal expansion between the metal and the plastic (metal 〈16.5mm / mm ℃ × 10 ^-6 , plastic〉 60mmmm ℃ × 10 ^-6 ) In hot water pipe used at 60 ~ 80 ℃, there is a risk of water leakage on the screw part. The plastic screw part may be broken or wear may occur, so that an independent nipple shaped metal screw 33 having a threaded part as shown in FIG. 12 is inserted into the body when the plastic T-shaped fitting 32 is molded and integrated. It is made by using it.

The shock absorbing device accommodated in the upper body of the T-shaped pipe fitting (1) is made of a flexible tube 34, which is made of a rubber pleat, as shown in Fig. 13, to the upper body of the T-shaped pipe fitting (1). Accepted and used.

The flexible tube 34 has an outer diameter of 1 to 3 mm less than the upper body inner diameter of the T-shaped fitting 1, and is formed to have the same length as the length of the upper body, and the initial compression tension in the inner diameter space portion. And both ends of the stainless steel compression spring (8a) and the stainless steel compression spring (8a), which hold the specified allowable load strength, are supported by stainless washers (4). It is manufactured in a sealed structure that is 100% blocked.

When the flexible tube 34 shock absorber performs compression movement at the shear strength of the shock wave, the gas 35 is naturally filled in the inner diameter space of the sealed flexible tube 34 according to Boyle's law. The stainless steel compression spring 8a has a predetermined allowable load and absorbs and cushions the shock while compressing.

In addition, the flexible tube 34 omits the stainless steel compression spring 8a and washer 4 accommodated in the inner diameter space portion, and the gas 35 such as nitrogen or air is about 4 to 6 kg / cm ² higher than atmospheric pressure. Of course, it can be used as a shock absorbing device using the law of Boyle by filling the gas (35) by the pressure of the pressure.

1. The shock absorber is installed directly above and below the valve that the faucet opens and closes to maximize the shock absorption ability.

2. Increase pipe life by protecting pipes and their accessories from water hammer

3. As the shock absorber is integrated in the pipe fitting, the air in the pipe is shortened, and the construction cost is not required.

4. There is no need for a separate installation space

5. Adjust water supply more than necessary to save water

6. The water supply is balanced in the high and low parts of the building, providing a high level of service for the equipment technology.
