Referring to fig. 1, an embodiment of the invention provides a pressure regulating device 100 for regulating the pressure of a gas or a liquid. The pressure adjusting device 100 includes: the diaphragm valve comprises a shell 10, a diaphragm 20, an elastic body 30 and a plane valve 40, wherein the diaphragm 20, the elastic body 30 and the plane valve 40 are arranged in the shell 10; the shell 10 comprises a first accommodating cavity 11 and a second accommodating cavity 12 which are connected in sequence; a through hole 13 is arranged between the first accommodating cavity 11 and the second accommodating cavity 12; the membrane 20 and the elastic body 30 are arranged in the second accommodating cavity 12, and one end of the membrane 20 is connected with one end of the elastic body 30; the diaphragm 20 covers the through hole 13, the periphery of the diaphragm 20 abuts against the peripheral wall of the second accommodating cavity 12, the planar valve 40 comprises a pressure adjusting rod 41 and a movable rod 42 connected with the pressure adjusting rod 41, the planar valve 40 is arranged in the first accommodating cavity 11, and the movable rod 42 extends into the second accommodating cavity 12 and is connected with the elastic body 30; a channel 111 is arranged in the first accommodating cavity 11, and the pressure adjusting rod 41 is movably arranged in the channel 111; when the gas or liquid entering the first receiving cavity 11 passes through the through hole 111 and pushes the diaphragm 20 to press the elastic body 30, the elastic body 30 moves away from the first receiving cavity 11 and drives the movable rod 42 to pull the pressure adjusting rod 41 to move relative to the channel 111, so that the pressure of the gas or liquid in the channel 111 is reduced.
In this embodiment, the pressure adjustment rod 41 is disposed in the first receiving cavity 11 of the housing 10, so that the pressure adjustment rod 41 is movably mounted in the channel 111, and the diaphragm 20 and the elastic body 30 are disposed in the second receiving cavity 12, so that the elastic body 30 and the movable rod 42 in the first receiving cavity 11 are connected with each other, so that when the pressure of the gas or the liquid entering the first receiving cavity 11 is unstable, the elastic body 30 is pressed by the diaphragm 20, and the elastic body 30 drives the movable rod 42 to pull the pressure adjustment rod 41 to move relative to the channel 111 in a direction away from the first receiving cavity 11, so that the flow rate and the pressure of the gas or the liquid in the channel 111 are reduced. In this way, the flow rate and pressure of the gas or liquid flowing out of the outlet 62 are stabilized by the self-stabilization regulation of the pressure-regulating device 100.
In this embodiment, the housing 10 is made of stainless steel material, which can ensure that the housing 10 is not corroded or rusted when the housing is used for a long time in liquid or gas, thereby prolonging the service life of the pressure regulating device 100. The housing 10 includes a first receiving chamber 11 and a second receiving chamber 12. An inlet 61 and an outlet 62 are arranged in the first accommodating cavity 11 at intervals, the inlet 61 is used for introducing gas or liquid, and the outlet 62 is used for discharging the gas or liquid. In other embodiments, the housing 10 may also be made of electro-galvanized steel or hot-galvanized steel, and may be set according to actual situations.
In this embodiment, a passage 111 is disposed in the first accommodating cavity 11, and the passage 111 is formed by a first retaining wall and a second retaining wall that are disposed opposite to each other. The channel 111 is used to convey liquid or gas introduced through the inlet 61. When the diameter of the passage 111 is reduced, the flow rate and flow velocity of the gas or liquid flowing therethrough are reduced, and the flow rate and flow velocity of the gas or liquid discharged from the outlet 62 are also reduced accordingly. Further, the inner diameter of the passage 111 increases in a direction away from the second receiving chamber 12. This helps regulate the flow and velocity of the gas or liquid into the channel 111. When the cross-section of the passage 111 is trapezoidal, the flow rate of the gas or liquid is small when the gas or liquid passes through the passage 111 having a small inner diameter. When the gas or liquid passes through the passage 111 having a large inner diameter, the flow rate of the gas or liquid is large. In other embodiments, the cross-section of the channel 111 may also be curved. The method is specifically set according to the actual situation.
As shown in fig. 1, the first receiving chamber 11 is shown to be provided with a planar valve 40. The plane valve 40 includes a connecting rod 43, and the connecting rod 43 connects the pressure adjustment rod 41 and the movable rod 42. Specifically, the pressure adjustment rod 41 is movably installed in the channel 111 to control the flow rate of the gas or liquid in the channel 111. The movable rod 42 is connected and fixed to the elastic body 30 to push the pressure adjustment rod 41 to move in the channel 111. The connecting rod 43 connects the pressure adjustment lever 41 and the movable lever 42. Thus, when the movable rod 42 moves away from the first receiving cavity 11 under the driving of the elastic body 30, the pressure adjusting rod 41 enters the channel 111 along the direction of the second receiving cavity 12 through the connecting rod 43 and under the driving of the movable rod 42, so as to reduce the flow rate and pressure of the gas or liquid flowing through the channel 111.
In this embodiment, the second receiving cavity 12 is provided with a membrane 20. The membrane 20 is made of a flexible material that is stretchable. The periphery of the membrane 20 is in sealing contact with the second accommodating cavity 12. Thus, when there is no gas or liquid in the first receiving chamber 11, the diaphragm 20 is attached to the inner wall of the second receiving chamber 12, and separates the first receiving chamber 11 and the second receiving chamber 12 from each other. The gas or liquid enters the first receiving chamber 11 and flows into the through-hole 13. Because the gas or the liquid is formed by compression, the internal pressure of the gas or the liquid is large, so that the flow rate of the gas or the liquid is high. Thus, the gas or liquid with a fast flow rate pushes the membrane 20 to stretch in a direction away from the first receiving cavity 11, and drives the elastic body 30 to contract. The membrane 20 can be used for isolating the elastomer 30 from the gas or liquid, and can also be used for moving along the second receiving cavity 12 under the extrusion of the gas or liquid.
In this embodiment, the elastic body 30 is a spring, one end of the spring is fixed with a push plate 31, the other end of the spring is provided with a connecting plate 32, the push plate 31 is connected with the diaphragm 20 in a sealing manner, and the connecting plate 32 is used for abutting against the elastic body 30. Specifically, the spring satisfies hooke's law F ═ kx, and when the pressure of the gas or liquid flowing into the first housing chamber 11 is P, the diaphragm 20 stretches and presses the spring to contract away from the first housing chamber 11, and the force applied to the spring is F, and the movement distance of the spring is x. The spring drives the movable rod 42 to pull the pressure adjustment rod 41 to move, and the pressure adjustment rod 41 is inserted into the channel 111 along a direction away from the first accommodating cavity 11. The moving distance of the pressure adjustment lever 41 is also x without considering the frictional force1. When the pressure adjustment rod 41 is completely inserted into the channel 111, the pressure adjustment rod 41 is attached to the channel 111, so that the movement distance is x1Next, the gaps between the first and second retaining walls and the pressure adjustment rod 41 become smaller, the flow rate, flow speed and pressure of the gas or liquid in the passage 111 decrease, and at this time, the pressure of the gas or liquid is P-P1. By providing the planar valve 40 in the first housing chamber 11 and the diaphragm 20 and the elastic body 30 in the second housing chamber 12, it is possible to reduce the pressure of the gas or liquid flowing into the first housing chamber 11 when the pressure of the gas or liquid is high, and to stabilize the pressure of the gas or liquid flowing out of the outlet 62 in a balanced state. In other embodiments, the pressure regulating device 100 may also realize that when the pressure of the gas or liquid flowing into the first receiving cavity 11 is small, the pressure of the gas or liquid may be increased.
Further, when the pressure of the gas or liquid flowing into the first containing chamber 11 is unstable, that is, the pressure becomes P-P2At this point, the force with which the diaphragm 20 presses the spring is reduced, i.e. the spring is subjected to a force F-F1The compression distance of the spring is reduced to x-x2. The spring drives the movable rod 42 to pull pressureThe adjusting rod 41 is moved, and the pressure adjusting rod 41 extends out of the channel 111 along the direction away from the second accommodating cavity 12. The moving distance of the pressure adjustment lever 41 is also x-x without considering the friction force2. At a movement distance of x-x2Next, the gaps between the first and second retaining walls and the pressure adjustment rod 41 become larger, the flow rate of the gas or liquid passing through the passage 111 increases, the flow rate also increases correspondingly, the pressure increases, and the pressure of the gas or liquid is P-P2+P3. This way, a pressure variation value P can be achieved which is regulated by self-regulation3The pressure value P is obtained by canceling the unstable influence of the pressure of the gas or liquid flowing into the first accommodation chamber 112The influence of (c). By providing the planar valve 40 in the first housing chamber 11 and the diaphragm 20 and the elastic body 30 in the second housing chamber 12, it is possible to adjust the pressure of the gas or the liquid in time when the gas or the liquid flowing into the first housing chamber 11 is unstable. The flow rate of the gas or liquid discharged from the outlet 62 communicating with the passage 111 is stabilized, that is, the pressure of the discharged gas or liquid is uniformly stabilized, by the self-stabilization adjustment of the pressure-adjusting device 100.
As shown in fig. 1, a hole (not shown) penetrating the first receiving cavity 11 and the second receiving cavity 12 is formed between the first receiving cavity 11 and the second receiving cavity 12, a sealing ring 14 is disposed in the hole, and the movable rod 42 passes through the sealing ring 14 and slides in the sealing ring 14. In particular, the sealing ring 14 is used to prevent gas or liquid flowing through the channel 111 from flowing back into the second receiving cavity 12. In addition, the movable rod 42 passes through the sealing ring 14 and is connected to the elastic body 30. The movable rod 42 is movable within the seal ring 30.
In this embodiment, the pressure adjusting apparatus 100 further includes a manual adjusting unit (not shown); the manual adjusting part comprises a manual knob 51 and a rotating screw 52; the manual knob 51 is disposed outside the housing 10, and the rotary screw 52 extends into the second receiving cavity 12 and is connected to the connecting plate 32 of the elastic body 30. Specifically, the rotary screw 52 of the manual adjustment part may extrude the connection plate 42 by rotating the extrusion connection plate 42, so that the connection plate 42 is extrudedThe elastic body 30. When the pressure of the discharged gas or liquid is unstable, i.e. the pressure of the gas or liquid is P-P4When is, P4Is the pressure variation value. By rotating the manual knob 51 of the manual adjustment part, the rotary screw 52 presses the connection plate 32, and the connection plate 32 presses the spring, i.e. the spring is subjected to a force of F + F2，F2Is the force at which the spring is applied. The movement distance of the spring along the direction far away from the second accommodating cavity is x + x2. The spring drives the movable rod 42 to pull the pressure adjustment rod 41 to move, and the pressure adjustment rod 41 extends out of the channel 111 along the direction away from the second accommodating cavity 12. The moving distance of the pressure adjustment lever 41 is also x + x without considering the friction force2. At a moving distance of x + x2Next, the gaps between the first and second retaining walls and the pressure adjustment rod 41 become larger, the flow rate of the gas or liquid passing through the passage 111 increases, the flow rate and the pressure increase accordingly, and the pressure of the gas or liquid is P-P4+P5. This makes it possible to achieve a variable value P by applying a pressure5Offset the pressure variation value P4The influence of (c). By providing the manual adjustment portion to the pressure adjustment device 100, the pressure of the gas or liquid at the outlet 62 can be discharged. In this way, the pressure adjusting device 100 can also stabilize the flow rate of the gas or liquid discharged from the outlet 62 communicating with the passage 111, i.e., the pressure of the discharged gas or liquid is uniform and stable, by manual adjustment.
In this embodiment, the manual adjustment portion further includes a protection cover 53 and a fixing portion 54 fixed to a periphery of the protection cover; the protective cover 53 extends into the second receiving cavity 12 and is fixed on the connecting plate 32. Specifically, the protective cover is used for fixing the manual knob and the rotary screw on the pressure regulating device 100, and preventing the rotary screw 51 from contacting with the outside to influence the rotation precision of the rotary screw 51. The fixing portion 54 is used to fix the protection cover 53, so that the protection cover 53 is firmly fixed on the pressure regulating device 100.
In this embodiment, the pressure adjustment rod 41 is disposed in the first receiving cavity 11 of the housing 10, so that the pressure adjustment rod 41 is movably mounted in the channel 111, and the diaphragm 20 and the elastic body 30 are disposed in the second receiving cavity 12, so that the elastic body 30 and the movable rod 42 in the first receiving cavity 11 are connected with each other, so that when the pressure of the gas or the liquid entering the first receiving cavity 11 is unstable, the elastic body 30 is pressed by the diaphragm 20, and the elastic body 30 drives the movable rod 42 to pull the pressure adjustment rod 41 to move relative to the channel 111, so that the flow rate and the pressure of the gas or the liquid in the channel 111 are reduced or increased. In this way, the flow rate and pressure of the gas or liquid flowing out of the outlet 62 are stabilized by the self-stabilization regulation of the pressure-regulating device 100. Further, the pressure adjusting device 100 is provided with a manual adjustment portion including a manual knob 51 and a rotary screw 52. When the flow rate and pressure of the gas or liquid in the outlet 62 are unstable, the rotating screw 52 is rotated by the manual knob, so that the rotating screw 52 extrudes the elastic body 30, the elastic body 30 drives the movable rod 42 to pull the pressure adjusting rod 41 to move relative to the channel 111, and the flow rate and pressure of the gas or liquid in the channel 111 are reduced or increased.
