Abstract

An inner water pressure valve is provided to be mainly made of synthetic resin so as to reduce manufacturing cost and be applied to a chemical pipe. An inner water pressure valve includes a valve main body(1-1) composed of a valve body(1-2), a rubber(1-3), and a valve connecting unit(1-4). Air-tightness in the valve main body is maintained by bonding or applying heat to the valve connecting unit. The rubber interrupts a flow of fluid. A check valve unit is installed on the bottom of a buoyancy unit to fill water in a ball. When the water is filled in a water tank, the check valve unit is opened by the weight of the ball so that the water is filled in the ball. A screw unit is installed in the valve main body to be connected to a pipe so that the water is prevented from flowing laterally when discharged from the pipe.

 The history of the valve goes back hundreds of years. Valves are one of the most indispensable devices in fluid control, as the valves at the very beginning are the driving force of the industrial revolution. The rapid development of the early valves may be due to their application to the industrial revolution.

 The valve for the toilet was started by the famous fluid mechanic Bernoulli's population due to the industrialization of the large city, where the buoyant float valve was used.

 Since then, the principle of the valve has been changed in various ways, and it has continued to develop into industrial use, and the change in appearance, such as changing the direction of the basic principle, has continued to this day.

 The earliest float valves are used in the form of buoyancy spheres that are buoyantly controlled in the body of bronze and brass, so that the flow of fluid stops when a certain level is reached.

 This float valve is the most widely used to date even though there are many problems. This valve has problems such as continuous fluid leakage when the ball falls due to buoyancy control, difficulty in level control, continuous increase of rod fatigue due to buoyancy and leakage at high pressure.

 The metered discharge valve is applied to needle valve, control valve, etc., which implies the reason of forcibly controlling the internal pressure of the fluid and the disadvantages of leaking in the case of the insertion of foreign substances in the water and the disadvantages of precision processing.

 The solenoid valve has the advantage of controlling the water and sewage level by receiving the electric signal by connecting the strength and the sensor to control the flow rate by distinguishing the on-off state. However, if electricity is required and the sensor in the water is used, there is a problem that frequently occurs due to the malfunction of the sensor due to the scale, and there is a risk of deduction due to maintenance and use with water because of the use of electricity. In addition, an increase in price due to precision machining is one of the important problems.

 Strainers are currently widely used in casting products, but the inside is not visible, so the inflow of foreign matters is not known, and the removal of foreign matters has the disadvantage of loosening the connection part. The structure is complicated, the number of parts is various, and the price is high because of the metal processing, and the pipe supporting the heavy weight must be strong as well.

 The gate valve has a horizontal pipe flow and the angle valve is bent to control the direction, which may result in an imbalance in the pressure of the fluid, and the ball valve has a problem of precision processing in which the precision of the ball must be secured. .

 Steam traps are mostly used with the float valve fixed inside. Like float valves, application problems and processes are complex and often result in failures.

 The check valve has been used for a long time, but recently, the pump breakage due to the rapid reverse water blocking has become a problem, and the Smorensky check valve is widely used, and the water hammer due to the rapid reverse flow blockage has been largely solved. .

 These valves are indispensable in the operation of the fluid.

 The types vary depending on the purpose. Generally, the most widely used are stop valves (globe valves and angle valves), check valves, pressure reducing valves, and the like. The type and dimensions of the valve are specified in the standard.

 The present invention is basically an invention using internal water pressure.

Based on the principle of the Republic of Korea Patent [2003-0019166, 2003-0076526], the present invention is further expanded form and the principle of the present invention is basically operated by the internal pressure, the material is also made of synthetic resin away from the existing metal Is possible. Synthetic resin has various characteristics according to the material. In general, plant piping is difficult to use a synthetic resin due to the fear of fire, etc. If the structure of the present invention made of a synthetic resin can be given a variety of properties. When the flow of the fluid is controlled by a physical force as in the conventional valve, there is a problem such as damage to the valve, but the present invention can be arbitrarily manufactured using general metal or synthetic resin, etc., by using a hydraulic pressure inside. In other words, if manufactured with synthetic carbonate (PC), the heat resistance reaches 130 degrees and can be used for high temperature water. If it is made with ABS, the heat resistance is 80 degrees, so it can be applied to general cold water or pneumatic. When manufactured with PE, the chemical stability can be secured, so that various chemicals can be stored and transported in chemical tanks, wastewater treatment plants and water purification plants.

 In addition to these material properties, the present invention may be further developed and the use area may be expanded in structural properties.

 In the present invention, while using the internal water pressure it is applied to various more advanced valves.

 The configuration and operation principle of these valves will be described in detail as follows.

 The precision of the valve portion in the figure is very important for maintaining the airtightness of the entire valve. The valve body (1-1) is composed of the valve body (1-2), rubber (1-3), valve connection (1-4) and the end portion by gluing 1-5 or applying heat (1--1) 6) Prevents air tightness due to internal pressure. In addition, install the check valve part of 1-8. This is to solve the problem such as breakage of the ball and mounting the water in the ball because the valve is used to fill the water inside the ball when moving the machine mounted. That is, when the valve is installed and the water is filled into the water tank, the check valve is opened by the gravity of the ball, and the water is filled by itself, and once the cold water is maintained until the portion except the buoyancy part, there is no need to fill the water separately.

 1-9 is a threaded part that can be connected to the pipe in the valve body. It prevents water from flowing sideways and is easy to use when control is required in a separate direction. 1-10 is a part where the hose can be connected, and it can be easily used for controlling the sound when water flows.

 2 is a basic operation diagram of such a valve.

 3 is an application of the advanced form of 2003-0076526. Instead of the rod part, the screw is connected to the body to allow the valve to move from side to side as the screw is tightened. By applying this, it is possible to control the flow of the desired amount of fluid by fixing the discharge port of the valve in the desired shape. It can be used to replace the existing needle valve or regular discharge valve, and while the existing valves forcibly prevent the fluid from coming out, this valve has a structure that prevents the water pressure inside, so the control is more convenient and there is no fear of failure. It is reduced and it is easy to use by connecting with other pipe to the pipe connection of 1-9. In the drawing, 3-1 indicates a screw connection part, and 3-2 moves a predetermined amount along a predetermined pipe without fluid flowing out while connected to another pipe.

 In FIG. 4, the valve is controllable in on-off form.

 In the cover 4-1 covering the body of the valve of the present invention, the fixing parts 4-2 and 4-3 for fixing the magnetic place are installed to fix the magnets and the steel piece fixing parts 4-3 and 4-4 to the support. Has In this case, the water level is increased so that the magnet 4-2 is attached to the iron 4-3. When the water level is lowered, gravity is generated on the ball. When this gravity beats the force of the iron pieces attached to the magnet, the ball falls down, and the bottom magnets 4-3 and 4-4 are attached (FIG. 5). This principle of operation also eliminates the drawback of a smaller discharge volume before the float valve becomes clogged and keeps the valve closed or open.

 Figure 6 relates to a non-powered two main water level valve of the present invention, conventionally a method of controlling the dual level by its own non-power, as opposed to controlling the dual level using electrodes or sensors. Disadvantages of the conventional valve using electricity requires a power source to operate a solenoid valve using an electrode or a sensor, and stops operation in the case of a power failure, causing many problems.

 It can be implemented by connecting a string to the on-off valve described in Figures 4 and 5. The principle of implementation of this valve is as follows.

 A water buoyancy part 6-2 is provided on the upper part of the valve which can be turned on and off by a string, and a heavy ring-shaped ring 6-1 is placed between the upper buoyant ball and the water buoyancy part. do. And underneath it is filled with water filling. Similarly, this hole can be provided with a check valve part like 1-8. As shown in FIG. 6, the valve is configured so that the lower ball is lowered at the full water level, and the water level is gradually lowered while using water continuously. When the water level is lowered further and the water in the gravity receives gravity (FIG. 7), the ring 6-1 is placed on the surface buoyancy portion 6-2. In this state, when the force of the magnet holding the support becomes lower than gravity, the upper hole falls down and the upper side maintains the shape of FIG. As water rises, the surface buoyancy rises and the lower ball remains perpendicular to the ground. The surface buoyancy keeps the closest distance to the ball due to the weight of the ring. And when the buoyancy is further increased, the support and the upper hole floats up to return to the state of FIG. The role of the ring is very important here. In the absence of a ring, the ball will be slowed up by water resistance at high specific gravity, and the support will be in the middle. The ring is located closest to the surface buoyancy and the upper hole, for this reason there is no malfunction since the support is raised only by the straps connected to the ring.

 In FIG. 10, the on-off valve of FIG. 4 is directly connected to the water pump and controlled. This valve is provided with a switch cover 10-2 on top of the valve of FIG. 4 to fix the on-off switch 10-1 therein. 10-5 and 10-6 are wires that connect to the water pump. And on one side of the support of Figure 4 is laid connection rod 10-3 capable of vertical movement. As shown in FIG. 10, the water pump is stopped while the switch bar 10-4 capable of on-off shorting is shorted. As described above, when the water level is lowered and gravity of the ball is generated and the support is lowered and the bottom magnet and the iron are attached, the connecting rod 10-3 is lowered and the switch bar 10-4 is lowered. Is activated (Fig. 11). Similarly, when the water level rises and the ball is raised by buoyancy, the connecting rod 10-3 rises and the switch rod 10-4 rises to serve to turn off the power of the water pump to directly operate the valve.

 Using this principle, it can be applied to FIG. 6 to implement an automatic double switch valve that arbitrarily controls the water level. It can be easily used for various fluid control to be independently controlled without being connected to the pipe.

 12 is an example of applying a conventional strainer using a valve using the internal water pressure of the present invention. Existing strainer stops the operation of the pipe in order to remove the foreign matter in the pipe and dismantles the screw, then the complex process that must remove the foreign matter in the network The present invention has the advantage that can remove the foreign matter during operation and disassembly Simultaneously has the possible advantages, the structure of the present invention can be manufactured with a transparent synthetic resin has the advantage of knowing the degree of accumulation of foreign matter inside.

 In the drawing, 12-1 is a screw portion that can be connected to the existing pipe, the structure having a fixed portion 12-2 for fixing the foreign matter filter plate (12-3) without flow inside the pipe, foreign matter filter plate is As shown in the figure, the valve holder 12-4 is provided. In the valve housing, the spring 12-6 pushes down the valve 12-5 during the operation of the pipe, and the inlet and the outlet are completely separated. If there is a large debris inside, it is possible to remove the debris by opening the cap (12-7). When the foreign matter is filled inside, when the valve is lifted up with a stick or the like, the foreign substance comes out through the opening 12-8. This operation is possible even during operation unlike conventional strainers.

12-9 represent a number of holes through which water can pass.

 13 is a valve using an internal water pressure for a conventional gate valve or ball valve.

 In the drawing, as shown in FIG. 3, a screw connection part is formed, and a screw part 13-2 is formed on the body of the valve so that the valve 13-3 moves exactly according to the movement of the screw. Accordingly, the discharge amount of the pipe can be controlled, and the valve is blocked by being engaged with the water pressure therein, facing upward by the force of the spring 13-4, and repeating opening and closing according to the screw part. In order to accurately position and operate this valve, a screw thread 13-5 is laid and an opening 13-6 is placed for manufacturing and maintenance.

 FIG. 14 is a diagram in which a strainer (FIG. 12) and a gate valve (FIG. 13) of the present invention are connected and used. In this case, it can be used for both the operation of the stray and the pipe.

 15 is an embodiment using the internal water pressure of the present invention replaces the existing air vent.

 The air vent of the present invention installed on one side of the pipe in the Figure is buoyancy portion 15-1 moves up and down along the rail (15-2), by forming a hole (15-2) on the upper side of the buoyancy portion of a predetermined or more Air is discharged upward through this hole.

 When the installation is started in the pipe for the first time, the buoyancy is raised due to the buoyancy, and the valve 15-5 connected thereto is lifted up, and air is continuously drawn out, and water is filled in the lower part. The water is filled with water while pushing the pressure of the spring 15-7 through the check valve 15-8. As the air of the buoyancy portion comes out, the water level to the hole 15-2 is maintained. Air in the pipe can also escape from the hole 15-2 and the rail 15-2 formed in the side surface. While the air is flowing in, the air is discharged to the outside through the valve (15-5), and the operation stops when the buoyancy part is filled with water and pressure is maintained. As it plays a role, it moves up and down in the rail 15-6, which holds a fixed position, and the external valve 15-4 and the spring 15-3 are external when water hammer or temporary vacuum is generated in the pipe. Air is introduced into the air vent.

 Figure 16 is an embodiment to increase the efficiency by applying the check valve to the present invention.

 In general, the check valve is intended to prevent backflow by stopping the flow of fluid. In addition, in the case of the Sorrensky check valve, etc., the water pressure must be at least a certain degree (0.3 ㎏ / ㎠) to operate the bar in the present invention uses the following method to solve this problem and faster operation.

 A number of small check valves are constructed on existing disc plates. As shown in the figure, a space for installing the valve 16-5 and the spring 16-6 to the existing disk 16-3 is fixed to the valve and the spring, but the disk and the spring support plate 16-2. Form a number of holes to allow water to flow through. Secure the valve and the spring with a separate lid (16-7). Conventionally, the present invention can be applied to various plate check valves, tilting check valves, and butterfly check valves. With this configuration, it is possible to operate even at a minute pressure and to operate immediately even if a sudden drop in water pressure occurs.

 17 is a valve that can be operated when a pressure of a predetermined pressure is applied by controlling the pressure of the spring with the rear handle. 17-1 is a pressure-adjustable spring, which adjusts the strength of the spring and the pressure regulating lever 17-2 to allow fluid to flow according to the pressure of the inlet.

 18 shows an example in which the valve of FIG. 17 is applied. When the valve is installed on the side of the check valve, the flow of water stops and the water hammer is generated due to the vacuum at the inlet side. However, when the present invention is applied, the fluid flows only along the pipe while the check valve is closed. The present invention for the purpose of the pass flows along the vacuum portion to a certain portion is eliminated the vacuum, has the advantage of preventing damage to the water hammer or water pump or pipes due to this.

 19 is a view of applying the present invention to the air vent, the ball 18-1 is condensed steam from the steam pipe inside the ball due to the buoyancy. If a gap occurs due to the buoyancy received, water is drained therebetween, and when the buoyancy is lost, the valve 18-2 is blocked by the internal pressure.

 The present invention can be applied to various parts of the piping material due to these various effects. This can be applied to pneumatic pressure as well as liquid control of the liquid phase.

 Conventional valves generally control pressure in the opposite direction of the flow of fluid, but most of the present invention has the advantage of using the internal water pressure that the fluid itself has, the higher the pressure is difficult to shut off the existing valve but the present invention is pressure The higher this is, the more advantageous the control is at the same time.

 In addition, the majority of the existing valve products are metal products such as castings or stainless steel, while a large part of the present invention can be manufactured with synthetic resins, but there is no problem in the hydraulic pressure required by the valves, thereby reducing the manufacturing cost and changing the material of synthetic resins. It can be applied to chemical piping. When the material of this valve is PE, it is stable to chemicals.
