Description

[0001] PRESSURE REDUCING VALVE WITH A HEATER Technical Field

[0002] The invention relates to a pressure reducing valve with a heater for use in high pressure pneumatic systems.

[0003] State of the Art

[0004] In the state of the art, pressure regulating valves are commonly used in industrial applications, hydraulic and pneumatic systems, power plants, chemical and petrochemical plants, the automotive industry, and water management systems. These valves are preferred to ensure safe and efficient operation by keeping the pressure constant or reducing it in a given system. In addition, by controlling the fluid pressure in the system, it extends the life of the equipment and saves energy. It is frequently used in engineering applications due to its compact structures, easy assembly, and maintenance advantages.

[0005] In the current system, there are patent / utility model applications and articles related to the subject. The utility model application numbered "CN205244516U" in the state of the art relates to a gas valve and focuses especially on the low temperature pressure reducer. The system reduces the effect of low temperature gases on these pipes by adding an insulation layer around the inlet and outlet pipes. The system includes a temperature sensor (thermal detector) and a controller. When the gas temperature falls below the level determined by the controller, the controller sends an alarm signal. In this way, it protects the user from improper use of the low temperature pressure reducer.

[0006] In the current system, there are mechanisms operating at 0-100 bar adjustment pressure. However, there are no features such as heaters and temperature readers in these systems. This may adversely affect the performance of the system, especially in cold weather conditions, and may lead to problems such as freezing of the fluid. In the current system, while the system is not active in cold weather, the air and water molecules inside freeze and block the regulator. Failure to monitor temperature changes makes it difficult for the system to operate safely in cases of excessive temperature or freezing. These deficiencieslimit the use of existing systems, especially in harsh environmental conditions or sensitive operations.

[0007] Another disadvantage of the current system is that the existing valves do not have a stainless material structure. This may adversely affect the durability and longevity of the system, especially in harsh environmental conditions of the valve.

[0008] In addition, there is no pressure gauge (manometer) showing the pressure at both the gas inlet and the gas outlet in the current system. There is a separate line with a flow meter at the outlet and there is an indicator showing only the inlet pressure in the body.

[0009] As a result, due to the negativities described above and the inadequacy of the current solutions on the subject, there is a need for new technologies that can operate reliably, long-lasting, and uninterruptedly in harsh environmental conditions, while at the same time providing pressure control and temperature management in an integrated way. Such systems will significantly improve operational efficiency and safety by improving performance in both industrial and military applications.

[0010] Brief Description and Objects of the Invention

[0011] The invention relates to a pressure reducing valve with a heater for use in high pressure pneumatic systems that meet all the above-mentioned requirements and eliminate the negatives and disadvantages of the existing system.

[0012] This invention is a pressure reducing valve system with integrated heater and temperature reader features, which allows the high-pressure gases to be adjusted safely and precisely in the range of 0-100 bar. The system provides continuous and reliable operation by preventing the fluid from freezing in cold weather conditions, and simultaneously controls the heater by monitoring the ambient temperature changes thanks to the temperature reader.

[0013] The invention shows superior performance in harsh environmental conditions and has been developed especially for military and industrial applications. The stainless material structure increases the corrosion resistance of the system and provides a long life. While the heater feature prevents frost-induced blockages and failures, it creates a safe and uninterrupted working environment by optimizing the energy efficiency of the temperaturereader system. This innovative solution offers significant advantages for users looking for high reliability and durability in gas pressure regulation.

[0029] Detailed Description of the Invention

[0030] The invention relates to a pressure reducing valve with a heater for use in high pressure pneumatic systems. The valve safely reduces the high-pressure gas up to 250 bar to the desired pressure in the range of 0-100 bar in high pressure gas applications. The developed valve can be used in vehicles, land vehicles, factories, production lines, transportation facilities and storage facilities.

[0031] Figure 1 shows the general view of the valve. The stainless body (1) forms the outer structure of the valve and contains the connection points of the components of the heater (7), pressure gauge (9), temperature reader (8) and the gas inlet and gas outlet points. The coil spring assembly (2) positioned in the body (1) adjusts the poppet (5) and piston (4) mechanism to reduce the high pressure. The counter thrust force from the coil springassembly (2) according to each pressure adjusts the position of the piston (4) mechanism in the body (1). The coil spring (10), on the other hand, pushes the poppet (5) more when the valve reaches the desired pressure and allows it to close the gas passage.

[0032] In the valve system, the gas inlet point is positioned on the upper side of the body (1) in a direction parallel to the horizontal axis of the valve with the heater (7), and the gas entering from this point is taken to the valve through the filter (6) mechanism. The gas outlet is located at the bottom of the body in a direction parallel to the vertical axis of the valve and allows the depressurized gas to be transferred out of the system.

[0033] In order for the valve to operate under all environmental conditions, a heater (7) positioned to be connected to the gas inlet on the main body (1) and a temperature reader (8) were added to the main body (1). The heater (7) operates according to the notification from the temperature reader (8). The energy of the heater (7) is provided through an external electrical source (24 Volt DC electrical source). With the help of this heater (7) and a temperature reader (8), the gas inside remains at the same temperatures constantly and prevents freezing in the case of working with air. In this way, the valve can operate at the desired performance in summer and winter.

[0034] The adjustment screw (3) is used to adjust the outlet pressure between 0-100 bar. As the adjustment screw (3) is tightened by the user, the coil compresses the springs in the coil spring assembly (2) and the thrust force of these springs increases. In this way, the pressure from the gas is overcome, and if the adjustment screw (3) is tightened until the desired gas pressure is reached, the outlet pressure of the valve increases. This value is controlled and fixed by a manometer positioned connected to the gas inlet and gas outlet line. The piston (4) moves the poppet (5) in the gas chamber thanks to the resistance from the coil spring assembly (2). Poppet (5) leaves the outlet chamber open up to the desired level and closes the room when the gas reaches the requested pressure between 0-100 bar. The filter (6) positioned around the poppet (5) and the coil spring (10) prevents dirt from entering the air entering the valve. The filter (6) also serves to capture the poppet (5).

[0035] The heater (7) positioned on the main body (1) prevents them from freezing by heating the valve in cold weather. The gas passing through the valve and the water vapor in the air are prevented from freezing. This problem is eliminated with the invention. The temperature reader (8), which is a sensor, measures the environmental temperature values and providesinformation to the software. The temperature reader (8) gives temperature information to the software of the system where the valve is used and starts or stops the heater (7). The connection of the valve with the software is provided by cables and connector interfaces. In this way, it is ensured that the heater (7) works in cold environments and the heater (7) is turned off when the temperature value reaches the desired level.

[0036] Figure 2 shows two pressure gauges (9). One of these pressure gauges (9) shows the inlet pressure of the gas and the other shows the outlet pressure of the gas.

[0037] The gas entering the system by the gas inlet shown in Figure 2 is primarily purified from foreign particles by passing through the stainless filter (6). Then, the gas moves through the hole where the poppet (5) works and applies pressure on the piston (4). Meanwhile, the coil spring assembly (2) holds the piston (4) in a certain position according to the pressure value set by means of the adjustment screw (3).

[0038] If the system pressure exceeds the desired value, the coil spring assembly (2) cannot hold the piston (4) and the piston (4) moves downwards. With this movement, the poppet (5) closes the inlet hole of the room with the help of the coil spring (10) and provides sealing on the surface. This mechanism continues the same movement repeatedly during the gas flow in order to keep the set pressure value in constant balance. Thus, the high-pressure gas coming into the line is safely transmitted from the gas outlet by reducing it to the desired pressure level. In addition, the pressure safety valve can be used in said system. When the pressure exceeds 250 bar, the use of a pressure safety valve, which can be placed in the main body (1) to safely reduce the pressure, is optional and can be added to the valve according to the user's request. The pressure relief valve is used to reduce the system pressure to 0-100 bar in areas where the maximum pressure is 250 bar and is durable up to 250 bar as inlet pressure. In systems with an air supply of more than 250 bar, the use of a pressure safety valve is desired.

[0039] Various tests were performed to show the usability of the valve developed by the invention in hot and cold environments. 0-100 bar regulator was mounted according to the assembly picture and measurement control was carried out. No problems were encountered in the installation and measurement controls. 1 -liter high pressure tubes were connected to the inlet and outlet lines of the regulator and the preparation for the test was completed by attaching a 0-250 bar manometer to the outlet line. 150±5 bar pressure was loaded from theinlet line and the outlet pressure of the 0-100 bar regulator was adjusted to 60±5 bar with the regulating valve. The unit was pressurized, and leakage checks were performed; no leakage was encountered. For the temperature test, a waiting period of 2 hours was applied. At the end of this period, leakage detection was not made, and it was confirmed that the set pressure value was 60±5 bar. All tests were completed, and the unit was prepared for the next test step.

[0040] At the end of the 1st test of the environmental conditions of the 0-100 bar regulator, successful results were obtained at the same pressure values (inlet pressure 150±5 bar and outlet pressure 60±5 bar). For the environmental conditions second test, the cabinet was programmed to stand at +55°C for 2 hours and the unit was subjected to the test. The operating temperature of the valve is in the range of -20°C and +50°C. During the test, the inlet pressure of the unit was 160±5 bar and the outlet pressure was 67±5 bar at +55°C. At the end of the test, it was confirmed that the inlet pressure was 150±5 bar and the outlet pressure was 60±5 bar when the unit reached room temperature and no gas leakage was observed in the inlet-outlet connections.

[0041] Tightness tests of the valve were also carried out. 0-100 bar regulator was mounted according to the assembly picture and measurement control was carried out. No problems were encountered in the installation and measurement controls. 1 liter aluminum high pressure tubes were connected to the inlet and outlet lines of the regulator and the preparation for the test was completed by attaching a 0-250 bar manometer to the outlet line. 180±5 bar pressure was loaded from the inlet line and the outlet pressure of the 0-100 bar regulator was adjusted to 60±5 bar with the regulating valve. The unit was pressurized, and leakage checks were performed, no leakage was encountered. The unit was taken to the waiting area for a 48-hour sealing test. At the end of the test, it was confirmed that there was no leakage in the unit, and it was determined that the set pressure value was 60±5 bar.
