Description

Technical Field

[0001] The utility model belongs to the technical field of pressure controllers, especially a step - by - step pressure regulating type pressure controller. Background Technique

[0002] In the existing pressure control system, as a core component, the pressure controller is widely used in various industrial fields, such as chemical industry, pharmaceutical industry, food processing industry, etc. However, there are some deficiencies in the actual application of traditional pressure controllers, especially in terms of shock absorption and protection performance. These problems directly affect the reliability and service life of the equipment. Traditional pressure controllers are often directly installed on the pump body or other mechanical equipment without a special shock - absorbing device. When the vibration generated during the operation of the equipment is directly transmitted to the pressure controller, in the long run, it may cause the internal components to loosen or even be damaged, affecting its normal operation.

[0003] After retrieval, such as the existing Chinese patent publication number: CN209761695U electronic pressure controller, which includes a middle cover, a rear cover arranged on the top of the middle cover, and a check valve seat arranged on the bottom of the middle cover. There is a water outlet on the right side of the middle cover, a pressure diaphragm is arranged on the top of the middle cover, a push rod assembly is arranged at the bottom of the pressure diaphragm and is matched with it, a water inlet is arranged at the bottom of the check valve seat, and a check valve assembly matched with the push rod assembly is arranged on the water inlet. A spring matched with the pressure diaphragm is arranged in the rear cover cavity. The check valve assembly includes a valve body, a cavity is opened inside the valve body, a magnet and copper particles are placed in the cavity from top to bottom, an opening is arranged at the bottom of the cavity, and a plug in interference fit with the opening is arranged on the opening.

[0004] The cited patent literature also has the same problem. The pressure controller is often directly installed on the pump body or other mechanical equipment without a special shock - absorbing device. When the vibration generated during the operation of the equipment is directly transmitted to the pressure controller, in the long run, it may cause the internal components to loosen or even be damaged, affecting its normal operation.

The detachable shock-absorbing mounting assembly includes a U-shaped clamping plate piece that fits and clamps to the upper part of the pressure controller assembly, a detachable inverted L-shaped detachable connecting plate that is detachably installed at the tail end of the U-shaped clamping plate piece, and a mounting base connected to the bottom end of the L-shaped detachable connecting plate;

[0009] Arc-shaped corner claws, two of which are symmetrically arranged and detachably installed at one end of the U-shaped clamping plate piece away from the L-shaped detachable connecting plate, and the inner wall of the arc-shaped corner claws closely adheres to the outer wall of the upper part of the pressure controller assembly;

[0010] Among them, the inside of the U-shaped clamping plate piece is a hollow structure, and coolant is stored in the inner cavity. The inner walls of the U-shaped clamping plate piece and the arc-shaped corner claws are both bonded with a first silica gel pad. The first silica gel pad elastically abuts against the outer wall of the pressure controller assembly. The first silica gel pad can play a role in shock-absorbing and buffering protection for the pressure controller assembly and the display screen. At the same time, the hollow structure of the U-shaped clamping plate piece and the coolant can be used for cooling and temperature reduction inside the pressure controller assembly, thereby increasing the service life of the pressure controller assembly.

[0011] Preferably in this solution, the pressure controller assembly includes an upper cover shell and a lower cover shell that are snap-connected together. The circumferences of the upper cover shell and the lower cover shell both have pipes, and a display screen is embedded in the top surface of the upper cover shell.

[0012] Preferably in this solution, extension ear plates are symmetrically and integrally connected to the bottom surface of the U-shaped clamping plate piece. Threaded holes are provided on the surfaces of the extension ear plates and the upper cover shell.

[0014] Preferably in this solution, a liquid injection pipe orifice is integrally communicated with one side of the top surface of the U-shaped clamping plate piece, and a liquid discharge pipe orifice is integrally communicated with one side of the bottom surface of the U-shaped clamping plate piece.

[0021] The coolant inside the U-shaped card plate member circulates through the liquid injection pipe orifice and the liquid discharge pipe orifice, which can effectively help the pressure controller assembly dissipate heat and prevent equipment failures or performance degradation caused by excessive temperature. At the same time, the liquid of the coolant inside the U-shaped card plate member can also play a role in buffering and shock absorption. When the pressure controller assembly is subjected to an external collision, the coolant absorbs this force inside the U-shaped card plate member, thereby achieving the effect of buffering and shock absorption.

[0022] The arc-shaped corner claws are connected to the U-shaped card plate member through fasteners, which is not only convenient for disassembly and assembly, but also can adjust the distance between the two according to actual needs to adapt to pressure controller assemblies of different sizes, improving the versatility and flexibility of the system.

[0033] This embodiment provides a stepwise pressure regulating type pressure controller as shown in Figures 1 to 5 the figure, including: a pressure controller assembly 1, a detachable shock-absorbing installation assembly 5, and an arc-shaped corner claw 10.

[0034] The pressure controller assembly 1 is installed in the pump body and is of a stepwise pressure regulating type; the pressure controller assembly 1, as the core part of the whole device, is responsible for realizing the pressure control function, is installed in the pump body and works in a stepwise pressure regulating manner, improving the accuracy and stability of pressure control.

[0035] The detachable shock-absorbing mounting assembly 5 is detachably arranged on the upper part of the pressure controller assembly 1. The detachable shock-absorbing mounting assembly 5 includes a U-shaped clamping plate member 6 that fits and clamps to the upper part of the pressure controller assembly 1, a reversely arranged L-shaped detachable connecting plate 7 that is detachably mounted at the end of the U-shaped clamping plate member 6, and a mounting base 8 connected to the bottom end of the L-shaped detachable connecting plate 7. The U-shaped clamping plate member 6 is part of the detachable shock-absorbing mounting assembly 5, and helps the pressure controller assembly 1 dissipate heat through the internal coolant circulation, extending its service life. The L-shaped detachable connecting plate 7 is used in cooperation with the U-shaped clamping plate member 6 and is fixed by the clamping method of the T-shaped block 17 and the T-shaped slot 18, which is convenient for installation and disassembly to adapt to different application scenarios. The mounting base 8 serves as the bottom support of the L-shaped detachable connecting plate 7, providing a stable mounting foundation.

[0036] There are two symmetrically arranged arc-shaped corner claws 10, which are detachably mounted at one end of the U-shaped clamping plate member 6 away from the L-shaped detachable connecting plate 7. The inner wall of the arc-shaped corner claw 10 closely adheres to the outer wall of the upper part of the pressure controller assembly 1. The arc-shaped corner claws 10 are symmetrically mounted at both ends of the U-shaped clamping plate member 6 and are in close contact with the outer wall of the pressure controller assembly 1, further enhancing the shock-absorbing effect.

[0037] Among them, the inside of the U-shaped clamping plate member 6 is a hollow structure, and coolant is stored in the inner cavity. The inner walls of the U-shaped clamping plate member 6 and the arc-shaped corner claws 10 are both bonded with a first silicone pad 12. The first silicone pad 12 elastically abuts against the outer wall of the pressure controller assembly 1. The first silicone pad 12 can play a role in shock-absorbing and buffering protection for the pressure controller assembly 1 and the display screen 4. At the same time, the hollow structure of the U-shaped clamping plate member 6 and the coolant can be used for cooling the inside of the pressure controller assembly 1, thereby increasing the service life of the pressure controller assembly 1. The first silicone pad 12 is bonded to the inner walls of the U-shaped clamping plate member 6 and the arc-shaped corner claws 10 and contacts the outer wall of the pressure controller assembly 1 to play a shock-absorbing and buffering role.

[0038] In this embodiment, the pressure controller assembly 1 includes an upper cover shell 2 and a lower cover shell 3 that are clamped together. The circumferences of the upper cover shell 2 and the lower cover shell 3 both have pipes, and a display screen 4 is embedded in the top surface of the upper cover shell 2.

[0039] In this embodiment, extension ear plates 13 are symmetrically and integrally connected to the bottom surface of the U-shaped clamping plate member 6. Threaded holes 9 are provided on the surfaces of the extension ear plates 13 and the upper cover shell 2. The extension ear plates 13 are connected to the upper cover shell 2 by bolts for firmly installing the U-shaped clamping plate member 6. The extension ear plates 13 are integrally connected with the U-shaped clamping plate member 6 and are used to be fixed to the upper cover shell 2 by bolts.

[0040] In this embodiment, an elastic fastening rope 11 is fixedly connected between opposite ends of two arc-shaped corner claws 10. The elastic fastening rope 11 is elastically tensioned and attached to the outer wall of the upper cover shell 2, so that the elastic fastening rope 11, the arc-shaped corner claws 10 and the U-shaped clamping plate member 6 are enclosed and connected together to form a frame structure surrounding the upper cover shell 2. The elastic fastening rope 11 is connected between the two arc-shaped corner claws 10, and through its elastic force, the U-shaped clamping plate member 6, the arc-shaped corner claws 10 and the elastic fastening rope 11 jointly form a protection frame, enhancing the stability and shock absorption capacity of the overall structure.

[0041] In this embodiment, a liquid injection pipe orifice 14 is integrally communicated with one side of the top surface of the U-shaped clamping plate member 6, and a liquid discharge pipe orifice 15 is integrally communicated with one side of the bottom surface of the U-shaped clamping plate member 6. Sealing plugs are connected in both the liquid injection pipe orifice 14 and the liquid discharge pipe orifice 15. The liquid injection pipe orifice 14 and the liquid discharge pipe orifice 15 are respectively located at the top and bottom of the U-shaped clamping plate member 6, and are used for injecting and discharging the coolant to maintain the circulating flow of the coolant inside the U-shaped clamping plate member 6 and the storage of the coolant.

[0042] In this embodiment, a T-shaped clamping block 17 is integrally connected to the middle position of the side of the U-shaped clamping plate member 6 facing away from the elastic fastening rope 11, and a T-shaped clamping groove 18 for the T-shaped clamping block 17 to fit and engage is provided on the inner wall of the L-shaped detachable connecting plate 7.

[0043] In this embodiment, a locking bolt 19 is threadedly connected to the outer wall of the L-shaped detachable connecting plate 7, and the screw end of the locking bolt 19 passes through the T-shaped clamping groove 18 and is threadedly connected to the T-shaped clamping block 17.

[0044] In this embodiment, second silicone pads 16 are bonded to the outer wall of the U-shaped clamping plate member 6 on both sides of the T-shaped clamping block 17, and the second silicone pads 16 elastically abut against the inner wall of the L-shaped detachable connecting plate 7. The second silicone pads 16 are bonded on both sides of the T-shaped clamping block 17 and contact the inner wall of the L-shaped detachable connecting plate 7, increasing the sealing performance and shock absorption performance of the clamping part. The T-shaped clamping block 17 and the T-shaped clamping groove 18 are used in combination, allowing the L-shaped detachable connecting plate 7 to be quickly assembled and separated from the U-shaped clamping plate member 6.

[0045] In this embodiment, a through hole 22 is provided inside each arc-shaped corner claw 10, and a fastener 20 is inserted into each through hole 22. The fastener 20 is a fastening rod with an external thread groove 21 at its free end.

[0046] In this embodiment, after the fastening rod passes through the through hole 22, it is threadedly connected to the U-shaped clamping plate member 6 through the external thread groove 21. It can not only disassemble and install the arc-shaped corner claws 10, but also adjust the distance between the arc-shaped corner claws 10 and the U-shaped clamping plate member 6, so as to meet the use of pressure controller assemblies 1 of different specifications. The fastener 20 is inserted into the through hole 22 inside the arc-shaped corner claw 10 and is connected to the U-shaped clamping plate member 6 through the external thread groove 21, facilitating the position adjustment and disassembly of the arc-shaped corner claw 10.

[0047] In this embodiment, the step-by-step pressure reduction should select a suitable method according to the actual application scenario. This solution preferably adopts the mechanical multi-stage pressure reducing valve method: by using a multi-stage pressure reducing valve to gradually reduce the pressure of high-pressure fluid. Each stage of the pressure reducing valve is responsible for reducing the pressure to the required level, and finally reaching the required set pressure. This method is usually used in the pressure reduction occasions of high-pressure gases or liquids.

[0048] Working principle:

[0049] For this step-by-step pressure regulating pressure controller, when the pressure controller assembly 1 is started and the system needs to adjust the pressure, the pressure controller assembly 1 starts to work, and adjusts the output pressure step by step according to the preset pressure value. The current pressure value and other relevant information are displayed in real time on the display screen 4 embedded in the top surface of the upper cover housing 2, which is convenient for the operator to monitor.

[0050] The U-shaped clamping plate member 6 stores coolant inside. The coolant is replenished and discharged through the liquid injection pipe orifice 14 and the liquid discharge pipe orifice 15 to keep the coolant inside the U-shaped clamping plate member 6 circulating, which helps to dissipate the heat of the pressure controller assembly 1. The inner walls of the U-shaped clamping plate member 6 and the arc-shaped corner claws 10 are both bonded with the first silicone pads 12. These silicone pads elastically abut against the outer wall of the pressure controller assembly 1 to absorb the vibration from the outside and reduce the impact on the pressure controller assembly 1. At the same time, the liquid of the coolant inside the U-shaped clamping plate member 6 can also play a role in buffering and shock absorption. When the pressure controller assembly 1 is subjected to an external collision, the coolant absorbs this force inside the U-shaped clamping plate member 6, so as to achieve the effect of buffering and shock absorption.

[0051] The elastic fastening rope 11 is fixed between the two arc-shaped corner claws 10. Through its elastic action, the U-shaped clamping plate member 6, the arc-shaped corner claws 10 and the elastic fastening rope 11 form a tight frame structure, enhancing the overall stability and shock absorption effect. The bottom surface of the U-shaped clamping plate member 6 is symmetrically connected with extension ear plates 13. The extension ear plates 13 are aligned with the threaded holes 9 on the upper cover housing 2, and the U-shaped clamping plate member 6 is fixedly installed by bolts. The arc-shaped corner claws 10 are connected with the fasteners 20 through the through holes 22 inside them. The external thread path 21 of the fasteners 20 is threadedly connected with the U-shaped clamping plate member 6. In this way, the arc-shaped corner claws 10 can be disassembled and installed, and the distance between it and the U-shaped clamping plate member 6 can be adjusted to adapt to pressure controller assemblies 1 of different specifications.

[0052] The inner wall of the L-shaped detachable connecting plate 7 is provided with a T-shaped card slot 18, and the T-shaped card block 17 integrally connected to the U-shaped clamping plate member 6 is snap-fitted with it. The outer wall of the L-shaped detachable connecting plate 7 is fixed by a locking bolt 19, so that the T-shaped card block 17 is tightly connected with the T-shaped card slot 18. The second silicone pads 16 are bonded to both sides of the T-shaped card block 17. These silicone pads elastically abut against the inner wall of the L-shaped detachable connecting plate 7, increasing the sealing performance of the clamping part and further enhancing the shock absorption effect.

[0053] In the working state, the pressure controller assembly 1 is protected by the upper cover housing 2 and the lower cover housing 3 to avoid being interfered by the external environment. The shock-absorbing structure composed of the U-shaped card plate member 6 and the arc-shaped corner claws 10 effectively reduces the impact of mechanical vibration on the pressure controller assembly 1 and extends the service life of the equipment. At the same time, the circulating flow of the coolant inside the U-shaped card plate member 6 also plays a role in cooling, ensuring that the pressure controller assembly 1 will not overheat during long-term operation, thereby improving its working stability and reliability.
