Description

Energy-saving large-capacity direct-acting precision pressure regulating filter valve

This creation is about an energy-saving large-capacity direct-acting precision pressure regulating filter valve. The main body is provided with a pressure regulating filter valve with a main valve port and a secondary valve port. When the pressure passes through the pressure regulating filter valve, the transmission is adjusted. The pressure regulating spring inside the pressure seat adjusts the pressure to the flow straight rod, so that part of the flow can pass through the valve port first. When more flow is required, the main valve port can be opened, and the main valve port can be used. The pressure difference between the opening and closing of the valve port is reduced, so that the opening and closing of the main valve port and the secondary valve port are more rapid and stable. Since the area of the main diaphragm is much larger than the area of the secondary valve port, the purpose of precise pressure regulation is better.

The conventional direct-acting precision pressure regulating valve (90), as shown in Figures 7-8, can be seen in the constant-motion precision pressure regulating valve (90), which is provided with a pneumatic fluid (PP) input. The inlet end (PA) and the outlet end (PB) for discharge are provided with a valve port (91) between the two ends, and the valve port (91) is mainly applied through the diaphragm (93) and the spring (92). Pressure to control the amount of pressure fluid (PP) consumed at the intake end (PA) and the pressure and flow rate at the outlet end (PB);

In the figure, it can be seen that the structure for controlling the valve port (91) is a column, and the top end thereof is pressed against the diaphragm (93) by the elastic force of the main spring (94), so that the valve port (91) is opened. The bottom end is closed by the elastic force of the spring (92) to close the valve port (91), so that the action of the valve port (91) when opening or closing can be clearly understood, when the pressure at the outlet end (PB) is reduced, It is multiplied by (the diaphragm (93) area - the valve port (91) area) equal to the amount of force reduction, which is divided by the spring constant of the main spring (94) equal to the displacement of the main spring (94), By opening the valve port (91) by the displacement spring (94), the pressure at the outlet end (PB) rises. Therefore, if the pressure is to be precisely adjusted, the area of the valve port (91) should be reduced to increase the displacement. Minimize the flow and pressure as a precise pressure regulation;

The conventional direct-acting precision pressure regulating valve (90) considers that reducing the valve port (91) area is equivalent to reducing the maximum flow rate, therefore, the valve port (91) area cannot be reduced, and the conventional technique is to change the overflow hole (96). The normally open mode, by consuming some air consumption to the atmosphere, to precisely regulate the output pressure. This method makes the direct-acting precision pressure regulating valve (90) waste some energy of the air source.

As mentioned above, the flow straight rod (95) of the valve port (91) is designed to meet the larger flow demand, the diaphragm (93) of the internal structure of the direct-acting precision pressure regulating valve (90), Components such as springs (92)... must also be scaled up accordingly, which will make the volume of the direct-acting precision pressure regulating valve (90) larger and the air consumption of the overflow hole (96) Increase, so, when the user adjusts the control, the torsional force is also bound to increase, and when the valve port (91) is increased in size, even if a small displacement is turned on to raise the set pressure or output a small flow rate, it will be in a very short time. Inside, there is a large flow rate rapidly passing through the valve port (91), it is difficult to make a slight control, and the air consumption of the overflow hole (96) is more serious, so it is known by the above structure after practical application and research. There are disadvantages that must be improved.

This creation is an energy-saving large-capacity direct-acting precision pressure regulating filter valve. Its main technical purpose is to use the flow straight rod to match the main diaphragm and the main and secondary valve port springs to apply pressure on both ends to make the main valve. The port and the secondary valve port can be opened and closed according to the flow demand, which can reduce the unnecessary flow waste, and the secondary valve port can easily control the small flow rate and accurately adjust the set pressure, and increase the size at the main valve port to increase the flow rate. At the same time, the secondary valve port must be increased in size, and the large-capacity direct-acting precision pressure reducing valve can always achieve the purpose of accurate output pressure.

Secondly, the technical purpose is to design the two-stage opening and closing valve, which can make the flow from small to large to match the opening and closing of the opposite valve, so the pressure difference between the primary side pressure and the secondary side pressure can be reduced, and the output pressure can be reduced. Control becomes easier to control, and it can perform more precise pressure regulation, and can also avoid affecting the speed of opening and closing.

For the secondary technical purpose, the flow straight rod and the main and secondary valve ports of the two sections of the opening and closing are designed to avoid the proportional increase of the volume of the flow straight rod assembly occupying the internal space of the structure, so that the volume of the main body is maintained. In the same way, it is not necessary to increase the volume of the body as the flow demand increases, and the pressure regulating seat and the pressure regulating knob for control are also required to be increased in proportion, so that the torque consumed by the user in twisting the pressure regulating spindle is reduced. It is easier to compress the main spring to push the main diaphragm to achieve the desired output pressure.

The energy-saving large-capacity direct-acting precision pressure regulating filter valve is composed of a pressure regulating seat, a pressure regulating filter valve and a protective cover which is composed of a body connected from top to bottom. The pressure regulating filter valve has the function. The main passage for the primary side pressure and the secondary side pressure flow, the main passage is further provided with a main valve port and a secondary valve port, thereby forming a flow rate capable of periodically regulating the flow to the secondary side, and a flow straight rod After the pressure plug ring is sleeved by the straight rod, the straight rod ball seat is connected to the upper side of the straight rod, and the lower side of the straight rod is matched with the spring of the valve port spring, and the lower side of the pressure plug ring is provided with a The main valve port spring abuts, and the pressure plug ring displacement can be opened and closed for the main valve port, and the straight rod ball seat is pressed by the main diaphragm in the pressure regulating seat, so that the main body first uses the valve port Part of the flow is circulated, and when the main diaphragm adjusts the pressure, the flow straight rod can further open the main valve port, allowing the main valve port and the secondary valve port to pass more flow, the creation through the main valve port and The pressure difference between the opening and closing of the secondary valve port is reduced So that the main valve and the valve opening and closing times faster stable, the more precise voltage regulation and energy saving purposes.

Generally, according to the present creation, the best feasible embodiment, together with the detailed description of Figures 1 to 2 of the drawing, adds to the understanding of the creation;

The creation system is an energy-saving large-capacity direct-acting precision pressure regulating filter valve, and the structure thereof comprises: a body (10), which is composed of a pressure regulating seat (20) and a pressure regulating filter valve (30). And a protective cover (40) is sequentially connected from the top to the bottom. The protective cover (40) has a plastic cup (41) inside, and the plastic cup (41) is mainly used for the filter core seat (42). The filter holder (42) is provided with a filter core (43), and a bottom plate (44) is disposed in the filter holder (42);

Wherein, the pressure regulating filter valve (30) has a main passage (31) capable of circulating the primary side pressure (P1) and the secondary side pressure (P2), and the main passage (31) has a main valve port (32) therein. And a primary valve port (33) disposed inside the main valve port (32) for forming a flow regulation that can be circulated to the secondary side pressure (P2) in a phased manner, and below the valve port (33) A valve port spring (346) is provided for supplying the elastic force to close the secondary valve port (33), so that the valve port (33) has the function of elastic resetting, and the spring constant of the secondary valve port spring (346) must be smaller. Well, to achieve the purpose of precisely regulating the output pressure;

There is also a flow straight rod (34) which is sleeved by a straight rod (341) with a pressure ring (343). In more detail, when the pressure ring (343) is sleeved, there is still some space. The first section can be displaced, and the minimum displacement of the first section is 0.3 to 0.1 mm, so that the second section can be connected as early as possible, which can provide a larger flow output;

The straight rod (341) is connected with a straight rod ball seat (342) and a straight rod fixing seat (344) above, and the lower rod (341) is fitted with a valve port spring (346) to the top, and the pressure plug A main valve port spring (345) is abutted under the ring (343), so that the pressure ring (343) can be elastically displaced, thereby opening and closing the main valve port (32), and the straight ball seat (342) The main diaphragm (21) and the main spring (25) are pressed by the pressure regulating seat (20), so that the body (10) can first flow part of the flow rate and pressure with the valve port (33). The set pressure can be precisely regulated, and the overflow hole (26) can be completed without any air consumption flowing to the atmosphere, and the main diaphragm (21) adjusts the pressure increase, the flow straight rod ( 34) can continue to open the main valve port (32), so that the main valve port (32) and the secondary valve port (33) through a larger flow;

Please refer to Figure 2, in which the straight rod (341) is covered with a straight rod (3411) in the flow straight rod (34), and the surface of the straight rod seat (342) is also covered. The ball seat rubber (3421), together with the one shown in Figure 1, can clearly understand that the straight rod rubber (3411) is used to match the surface of the bottom of the straight rod holder (344). Closed valve port (33), pressure plug ring (343) also has pressure plug ring rubber (3431), can open and close the main valve port (32), and the ball seat rubber (3421) is used to strengthen and The contact degree of the main diaphragm (21) can be closed or opened to allow the secondary side pressure (P2) in the pressure regulating filter (30) to enter and exit to adjust the accuracy of the secondary side pressure (P2). The flow straight rod (34) is a two-stage structural design that further regulates the flow of the secondary side pressure (P2).

Referring again to Figures 3 to 4, when the primary side pressure (P1) passes through the primary passage (33) through the secondary valve port (33), it can be seen that the flow straight rod (34) has only the first section. The displacement is pushed down by the main diaphragm (21), and the flow required for the operation of the body (10) has not yet reached the maximum value; again, as shown in Figures 5 to 6, and when the flow straight rod (34) After being continuously pushed down by the main diaphragm (21), it can be seen that the pressure ring (343) is also pushed downward by the straight rod (341) to further open the second partial displacement, and the main valve port (32) is opened. At this time, the flow of the body (10) can be passed at a maximum value;

In the above-mentioned disclosure, an overflow hole (26) disposed on the side of the pressure regulating seat (20) can be seen, which belongs to a normally closed design when the flow rate passes through the main passage (31). The overflow hole (26) does not have any air consumption, so it can achieve excellent energy-saving effect on the body (10); in addition, the internal design of the conventional structure is relatively straight compared to the inside of the creation. The rod (34) is different from the main and secondary valve ports (32, 33). The other structures are mostly the same and can share parts. Therefore, when using the staged valve port design of this creation, it can be directly replaced. The flow rate can be improved without changing the volume of the body (10), and the research and development cost and time of re-opening manufacturing can be greatly saved; in addition, the creation of the main valve port can be known. When opening and closing the secondary valve port (33), the precision of the adjustment pressure can be ensured by reducing the area of the valve port (33) to the minimum area and maintaining the area of the main valve port (32) unchanged. It can be used under the flow and pressure conditions required by the conventional structure. Down to lower case, but also has a precise voltage regulation;

In summary, the creation of the energy-saving large-capacity direct-acting precision pressure regulating filter valve utilizes a two-stage opening and closing of the main flow through the flow straight rod (34) for general flow demand and maximum flow demand. The design of the valve port (32) and the secondary valve port (33) allows the total flow rate to be increased, and the relative reaction speed of the components can be increased, thereby allowing the primary side pressure (P1) and the secondary side pressure. The pressure difference between (P2) is reduced, allowing the user to control more effortlessly and easily, so that it has the function of precise pressure regulation, and when applied to a larger valve port, it is only necessary to expose the creation of two The design of the valve port at the stage can be improved into more segment designs, which can improve the defects of the large-capacity internal components in the past, and also make it easier for users to regulate and use.
