Energy-saving large-capacity precision pressure regulating valve

This creation is about an energy-saving large-capacity precision pressure regulating valve. It uses the internal pressure regulating straight rod and the direct-acting flow control straight rod to match the input pressure, so that the balance diaphragm and the main diaphragm are under pressure displacement. In time, the smooth vertical movement can be maintained, and the pressure inside the body can be formed into a fluid-free overflow state, which has the effect of energy saving, and can continue to adjust the high-precision output pressure.

Air compressor systems are commonly used in the field of automation equipment, and the most important part of the application is the precision pressure regulating valve, and the structure usually has an input end and an output end. After the preset pressure is input, the adjustment process is performed. In the middle, there will be fluid overflow. Although the final result can achieve the intended goal, the pressure source of the process overflow will also increase the cost of the overall operation. Long-term estimation will be a considerable expense.

In order to cope with the finer automated process in the future, it can be seen from the above situation that excessive energy consumption will inevitably affect the fluency of the overall operation; however, the market also has a precision pressure regulating valve designed to exchange high-precision output pressure with pressure energy overflow, but this The cost of the method is not optimistic for a long time; therefore, the inventors in the prior authoring structure, through the improvement of the internal passage, allow the input fluid to generate the equivalent pressure, and feedback each other, so that the energy loss is greatly reduced, and when When the excess fluid is removed, it can be quieter; although it has been seen to have a small effect, for the precision pressure regulating valve designed for large-capacity use, there is still a situation where the operation is not smooth, and it is based on the above structure after practical application and research. It is known that there are still shortcomings that must be improved.

The main technical purpose of this creation is the application of a large-flow precision pressure regulating valve, which guides the pressure through the passage inside the body structure, and is matched with the balance diaphragm, the main diaphragm, the pressure regulating straight rod, and the direct-acting flow control. Straight rods allow the pressure to be stable and high-precision, and the direct-acting flow control straight rod allows the pressure to be adjusted while maintaining the sensitivity of the internal components, not only allowing the fluid to remain closed and no longer overflowing, and It can increase the secondary side flow of the base output, making the efficiency of the body more ideal.

The energy-saving large-capacity precision pressure regulating valve of the present invention is a body composed of a pressure regulating seat, a middle valve seat, a main valve seat and a base, wherein the valve seat has a passage, a pressure regulating passage, and a piston is matched with a pressure regulating straight rod, and the passage and the pressure regulating passage can communicate with the base through the main valve seat, and another straight flow control straight rod is disposed between the main valve seat and the base, and the Inside the base, there are pressure regulating passages for pressure guiding, base orifices, overflow pipes, and adjusting valve ports, and a main diaphragm is disposed between the base and the main valve seat; The direct-acting flow control straight rod has the same force-applying area at the upper and lower ends, and is matched with the adjustable valve port support below. When the primary side pressure is input by the channel, the primary side pressure can be guided to the direct-acting flow control straight rod. At the upper end, the upper and lower ends are equally applied. When the main diaphragm pushes the direct-acting flow control straight rod, the vertical displacement can be smoothly performed, thereby closing the counterflow hole on the main diaphragm, so that the body can be under pressureless overflow.

Generally, according to the present creation, the best feasible embodiment, together with the detailed description of Figures 1 to 4, adds to the understanding of the creation; This creation is an energy-saving large-capacity precision pressure regulating valve having a body (1), and the body (1) is composed of a pressure regulating seat (2), a middle valve seat (3), and a main valve seat (4). And a base (5) is connected from top to bottom, and the middle valve seat (3) has a passage (6), a pressure-pressure passage (7), a balance pressure passage (8), and A piston (32) cooperates with a pressure regulating straight rod (33), and the outer edge of the piston (32) is integrated with a balance diaphragm (31), and the passage (6) and the pressure regulating passage (7) The main valve seat (4) can communicate with the base (5), and a constant flow flow control straight rod (41) is disposed between the main valve seat (4) and the base (5), and the base (5) internally has a pressure regulating passage (53) for guiding the pressure (P), a base orifice (55), an overflow pipe (54), and an adjustment valve port (52). And a main diaphragm (51) is further disposed between the base (5) and the main valve seat (4), and the piston (32) and the pressure regulating straight The outer layer of the rod (33) is made of a rubber material, which can enhance the sealing pressure effect, and can be replaced with a similar material having elasticity, and is not limited thereto.

The direct-acting flow control straight rod (41) has the same force-applying area (Pa) at the upper and lower ends, and is supported by the adjustable valve port (52) below the direct-acting flow control straight rod (41). When the balance pressure (Pt) input by the balance pressure channel (8) is enabled, the main diaphragm (51) can be guided to smoothly perform a vertical displacement operation, thereby closing the counterflow hole (511) to allow the body (1) It can continue to adjust the pressure (P) to output high-precision pressure without pressure (P) overflow.

Referring again to Figures 1 to 4, the pressure regulating seat (2) is internally provided with a main spring (22), and the outside is provided with a knob (21) for controlling the adjustment, and the main spring (22) is topped. Abutting the balance diaphragm (31), and guided by the pressure (P) inside the input body (1), a balance pressure (Pt) is formed; and the pressure (P) is externally adjusted to enter the body (1). Then, the primary side pressure (P1) is formed, and at the output, the secondary side pressure (P2) is formed.

When the primary side pressure (P1) is reduced by the pressure regulating passage (53) inside the base (5) with the base orifice (55), the primary side flow is reduced, and the primary side pressure (P1) is then passed through the middle seat (3). The main valve seat (4) is connected to the passage (6), and the primary side pressure (P1) is guided to the position of the pressure regulating straight rod (33), and the balance diaphragm (31) adjacent to the position will be subjected to the main spring. (22) pushing downward to form a balance pressure (Pt), at which point the portion of the balance diaphragm (31) at the center of the piston (32) will abut against the pressure regulating straight rod (33), and the The balance pressure (Pt) extends the balance pressure channel (8) continuously into the base (5), thereby pushing the main diaphragm (51) vertically displaced by the direct-acting flow control straight rod (41), and the base (5) an overflow pipe (54) provided at the bottom is connected to the direct-acting flow control straight rod (41), and the direct-acting flow control straight rod (41) is further provided at a central lower portion Adjusting valve port (52), the adjusting valve port (52) can be combined with a valve (56) having a supporting spring (57) for opening and closing adjustment action, and the adjustment source is For the aforementioned primary side pressure (P1), the primary side pressure (P1) of the direct acting flow control straight rod (41) is equal to the applied force area (Pa) at both ends, so that the main diaphragm can be transmitted through the main diaphragm. (51) is controlled by the support spring (57) and is not affected by the aforementioned primary side pressure (P1), and the primary side pressure (P1) of the adjustment type valve port (52) is adjusted as described above. The side pressure (P2) is subsequently circulated to the outside via the base (5), and the pressure regulating passage (7), the pressure regulating passage (7) is connected to the main valve seat (4) and the middle valve seat via the base (5) ( 3) Finally, up to the pressure regulating seat (2), the above is a state in which the secondary side pressure (P2) is >0.

When the secondary side pressure (P2) of the inside of the body (1) is adjusted, the primary side pressure (P1) originally circulating through the passage (6) will be regulated by the straight rod (33) and the pressure regulating straight The rod (33) valve top is blocked and blocked, and the primary side pressure (P1) originally flowing through the adjustment valve port (52) is also driven upward by the direct-acting flow control straight rod (41). (51) and the valve (56) restrict the primary side pressure (P1) from flowing, and at this time, the main body (1) is exhausted at the overflow hole (23) to make the inside of the body (1) The secondary side pressure (P2) = 0.

Furthermore, the adjustment valve port (52) is further provided with a central hole (521) in the center, and the central hole (521) can be replaced with different sizes according to actual production requirements. More specifically, the adjustment valve port (52) The area of the central hole (521): the cross-sectional area of the direct-acting flow control straight rod (41) passing through the central hole (521). If the ratio ≧4 or more, the base (5) can be obtained. The secondary side pressure (P2) output of the capacity and the maximum value of the flow rate can change the secondary side pressure (P2) output by replacing the area of the center port (521) with the adjustment valve port (52). And the strength of the traffic.

On the balance diaphragm (31), when the area of the secondary side pressure (P2) is multiplied by the secondary side pressure (P2): the area of the equilibrium pressure (Pt) multiplied by the equilibrium pressure (Pt), if the ratio is ≧ When it is 10 or more, the voltage regulation state of the secondary side pressure (P2) can be increased, and the diameter of the orifice (55) can be reduced, and the control action of the minimum intake air amount can be performed without wasting unnecessary pressure, so that it is known that when Secondary side pressure (P2) When it becomes larger, the main spring (22) can be pushed open immediately, and the excess equilibrium pressure (Pt) is discharged through the overflow hole (23), and the equilibrium pressure (Pt) continues to flow to the main membrane through the equilibrium pressure passage (8). The sheet (51), at this time, the secondary side pressure (P2) can push the counterflow hole (511) on the main diaphragm (51) to decrease the secondary side pressure (P2) into the equilibrium pressure (Pt). Until the voltage is stabilized, the secondary side pressure (P2) discharged through the counterflow hole (511) on the main diaphragm (51) is a pressure difference, and the noise volume is also greatly improved; if the secondary side pressure When (P2) becomes smaller, the main spring (22) can immediately push the balance diaphragm (31) and the pressure regulating straight rod (33), so that the primary side pressure (P1) enters through the valve port of the pressure regulating straight rod (33). The equilibrium pressure (Pt) is increased, and the equilibrium pressure (Pt) is continuously distributed to the main diaphragm (51) to push the main diaphragm (51) and the direct-acting flow control straight rod ( 41) Open the adjustment valve port (52) to increase the secondary side pressure (P2) until the voltage is stabilized.

Referring again to Figure 5, the creation structure is unidirectionally passed through the input primary side pressure (P1) to the secondary side pressure (P2), and the middle valve seat (3) is bidirectionally circulated. However, the middle valve seat (3) is matched with the counterflow hole (511) in the center of the main diaphragm (51) to achieve the opening and closing operation, and the balance pressure (Pt) is maintained correspondingly, and is matched with the main valve seat (4). The direct-acting flow control straight rod (41) is matched with the regulating valve port (52) to control the flow of the secondary side pressure (P2), so that the base (5) can also be bidirectionally circulated in actual operation, so Briefly explain how its structure works to make it easier to understand.

In summary, the creation of the energy-saving large-capacity precision pressure regulating valve is transmitted through the pressure regulating passage (53), the passage (6), the pressure regulating passage (7), and the balanced pressure passage (8) inside the body (1). The input pressure (P) is shifted by the pressure regulating straight rod (33) with the balance diaphragm (31) and the direct acting flow control straight rod (41) to drive the main diaphragm (51) to displace the body (1) The internal balance is maintained, and the air consumption of pressure (P) can be adjusted to increase the secondary side pressure (P2) or decompression under the condition of no overflow, so that the pressure energy can be improved and smooth.
