Description

Technical Field

[0001] The present invention relates to the technical field of valve production and detection, and particularly to a detection device for the production of automatic control valves. Background Art

[0002] Automatic control valves play an indispensable and crucial role in industrial process control systems. They are widely used to regulate the flow rate, pressure, and direction of fluids (such as gases, steam, water, or oil). These valves are not only the core components to ensure the smooth operation of the process flow, but also of great significance for improving production efficiency, ensuring safe operation, and achieving energy conservation and emission reduction goals. Therefore, in order to ensure that the quality of automatic control valves can meet high-standard requirements, a reliable and efficient detection device becomes particularly important.

[0003] Currently, in the field of flow rate detection for different opening degrees of control valves, the commonly used method is to perform tests using flow meters or flow sensors in a laboratory environment. However, this method usually involves multiple steps and operation links, which not only reduces the detection efficiency but also makes it difficult to quickly conduct quality inspections on a large number of control valves. Moreover, when relying on externally installed flow meters or pressure sensors for flow rate detection, these devices are easily affected by factors such as the working medium and the environment, resulting in inaccurate or invalid data. For example, under high-pressure difference conditions, corrosion inside the valve may change the characteristics of the flow path, further affecting the measurement accuracy of the sensor. Therefore, we propose a detection device for the production of automatic control valves to overcome the above defects. Summary of the Invention

Detailed implementation manners

[0026] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] Embodiment 1: A detection device for the production of automatic control valves, as Figures 1-4As shown in the figure, it includes a bottom plate 1, which is the assembly carrier of this detection device. A base frame 2 is fixedly installed on the bottom plate 1. On one side of the top of the base frame 2, an electric slide rail 1 3 is fixedly installed, and a mounting frame 4 is slidably assembled on the electric slide rail 1 3; it also includes a docking mechanism 5 arranged on the mounting frame 4. The docking mechanism 5 is used to dock the control valve 100 to be detected. The docking mechanism 5 includes a cylinder 51 fixedly installed on the mounting frame 4. There are two cylinders 51 and they are symmetrically distributed on the upper and lower sides of the top plate of the mounting frame 4. An upper docking head 52 is fixedly connected to the telescopic rod of the upper cylinder 51. A water supply pipe 53 is fixedly connected and communicated on the upper docking head 52. The upper docking head 52 is used to hermetically dock the water supply pipe 53 and the water inlet interface of the control valve 100 to be detected. A lower docking head 54 is fixedly connected to the telescopic rod of the lower cylinder 51. A water outlet pipe 55 is fixedly connected and communicated on the lower docking head 54. The lower docking head 54 is used to hermetically dock the water outlet pipe 55 and the water outlet interface of the control valve 100 to be detected; a weighing mechanism 6 for weighing the water flow rate of the control valve 100 is arranged on the bottom plate 1. The weighing mechanism 6 includes a plurality of electric push rods 61 fixedly installed on the bottom plate 1. The push rods of the plurality of electric push rods 61 are commonly fixedly connected to a lifting plate 62. A precision electronic scale 63 is fixedly assembled on the top surface of the lifting plate 62. A water receiving tank 64 is detachably assembled on the bearing plate 631 of the electronic scale 63. The water receiving tank 64 is adapted to and docks with the water outlet pipe 55. The water receiving tank 64 is used to collect the water flowing through the control valve 100 to be detected; a blowing member 7 for blowing air to the water outlet pipe 55 is arranged on the base frame 2. Place the control valve 100 to be detected between the upper docking head 52 and the lower docking head 54. Drive the upper docking head 52 and the lower docking head 54 to dock the control valve 100 through the cylinder 51, so that the water inlet and outlet of the control valve 100 can be hermetically connected to the water supply pipe 53 and the water outlet pipe 55. Synchronously lift the electronic scale 63 and the water receiving tank 64 assembled thereon through a plurality of electric push rods 61, so that the water receiving tank 64 is upwardly docked with the water outlet pipe 55. Then quantitatively open the valve core switch on the control valve 100 for a period of time, supply water to the control valve 100 through the water supply pipe 53. The flowing water flows through the control valve 100 and then flows into the water receiving tank 64 from the water outlet pipe 55. Preset to close the control valve 100 at a fixed time, use the water receiving tank 64 to collect the water volume flowing through the control valve 100 during this period of time, cooperate with the blowing member 7 to blow the water droplets that may remain in the control valve 100 and the water outlet pipe 55 into the water receiving tank 64. Subsequently, the electric push rod 61 drives the water receiving tank 64 on the electronic scale 63 to move downward and separate from the water outlet pipe 55. Record the change in the water receiving weight in the water receiving tank 64 by the electronic scale 63 for a period of time, and then calculate the weight of the water flow rate flowing through during the period when the control valve 100 is opened. Finally, within a reasonable error range, compare the actual water receiving volume of the water receiving tank 64 with the preset water volume flowing through the control valve 100 to detect whether the actual flow control of the control valve 100 meets the standard, so as to judge whether there are defects in the internal structure quality of the valve body of the control valve 100.

[0028] As Figure 2 and Figure 3As shown in the figure, the upper adapter 52 is composed of a first docking plate 521 and a first gasket 522. The first docking plate 521 is fixedly connected to the telescopic rod of the upper cylinder 51 above the mounting frame 4. A first gasket 522 is provided on the first docking plate 521. The first gasket 522 is connected to the water supply pipe 53. The first gasket 522 hermetically covers the docking part of the water supply pipe 53 and the water inlet interface of the detection control valve 100. The outlet of the water supply pipe 53 is a pointed nozzle and is docked and embedded into the water inlet interface of the control valve 100. The lower adapter 54 is composed of a second docking plate 541 and a second gasket 542. The second docking plate 541 is fixedly connected to the telescopic rod of the lower cylinder 51 below the mounting frame 4. A second gasket 542 is provided on the first docking plate 521. The second gasket 542 is connected to the water outlet pipe 55. The second gasket 542 hermetically covers the docking part of the water outlet pipe 55 and the water outlet interface of the detection control valve 100. The inlet of the water outlet pipe 55 is also a pointed nozzle and is docked and embedded into the water outlet interface of the control valve 100.

[0029] As Figure 2 , Figure 6 and Figure 7 shown, the air blowing member 7 includes a first air pump 71, a first air pipe 72 and a first nozzle 73. The first air pump 71 is fixedly installed on the base frame 2. A first nozzle 73 is installed at a position above the wall of the water outlet pipe 55. The nozzle of the first nozzle 73 is inclined upward in the water outlet pipe 55. The air outlet of the first air pump 71 is communicated with a first air pipe 72. The first air pump 71 is connected to the first nozzle 73 through the first air pipe 72. The first air pump 71 injects high-pressure gas into the first air pipe 72 and then sprays it out from the first nozzle 73. The first nozzle 73 continuously sprays high-pressure air flow obliquely upward on the inner wall of the water outlet pipe 55. Since the high-pressure air flow cannot pass upward through the closed control valve 100 on the inner wall of the water outlet pipe 55, the high-pressure air flow can only push the residual water droplets in the pipe wall downward along the water outlet pipe 55, so that the residual water droplets in the water outlet pipe 55 fully fall into the water receiving tank 64, thereby improving the accuracy of water collection in the water receiving tank 64.

[0030] As Figure 4 and Figure 5 shown, a circle of elastic sealing ring 641 is provided at the top tank opening of the water receiving tank 64. A sealing plate 56 is fixedly connected to the bottom pipe orifice of the water outlet pipe 55. The sealing plate 56 closely fits the sealing ring 641 on the water receiving tank 64 to improve the sealing performance when the water outlet pipe 55 and the water receiving tank 64 are docked. An exhaust valve 561 with one-way flow is installed on the sealing plate 56. The exhaust valve 561 is used to discharge the gas entering the water receiving tank 64. The sealing plate 56 cooperates with the sealing ring 641 to make the water outlet pipe 55 and the water receiving tank 64 be hermetically docked, reducing the interference of external factors on the water collection process of the water receiving tank 64 and reducing the error of the flow rate detection of the control valve 100.

[0031] As Figure 5 and Figure 7As shown, a humidity sensor 9 is installed at the lower part of the inner wall of the water outlet pipe 55. The humidity sensor 9 is used to detect the humidity change of the inner wall of the water outlet pipe 55. The humidity sensor 9 has a built-in controller. The humidity sensor 9 is electrically connected to the air pump 71 through the built-in controller. When the air pump 71 removes the residual water on the inner wall of the water outlet pipe 55 through air pressure, the humidity sensor 9 is used to monitor the humidity of the water outlet pipe 55 in real time. When the humidity in the water outlet pipe 55 drops to an appropriate range, the humidity sensor 9 can automatically shut down the air pump 71 through the controller.

[0032] like Figure 1 、 Figure 6 and Figure 8 As shown, a clamping member 10 for loading and detecting a control valve 100 is provided on the top of the base frame 2. The clamping member 10 includes an electric slide rail 101, a sliding plate 102 and a splint 103. An electric slide rail 101 is fixedly installed on the side of the top of the base frame 2 away from the mounting frame 4. The electric slide rail 101 is a bidirectional electric slide rail. Two symmetrical sliding plates 102 are installed on the electric slide rail 101. The splint 103 is fixedly connected to the sliding plate 102. The clamping surface of the splint 103 is elastic. The electric slide rail 101 can synchronously drive the splint 103 on the sliding plate 102 to move relative or back to back, so that the splint 103 can clamp the control valve 100 for detection, thereby improving the stability of the control valve 100 during flow detection.

[0033] When using this detection device to detect the flow rate of the control valve 100, the operator positions the control valve 100 to be detected in the clamping area in the middle of the base frame 2, enables and triggers the bidirectional driving function of the electric slide rail two 101. The electric slide rail two 101 drives the clamping plates 103 on the two sliding plates 102 on both sides to move towards the center of the control valve 100. The elastic clamping surface on the clamping plates 103 adaptively clamps the valve body shell of the control valve 100 to ensure that the control valve 100 does not displace during the detection process. Then, according to the positions of the water inlet and outlet joints of the control valve 100, the docking mechanism 5 on the mounting frame 4 is adjusted to the docking position by driving the electric slide rail one 3. Subsequently, the cylinder 51 on the mounting frame 4 is synchronously enabled. The telescopic rod of the upper cylinder 51 drives the upper docking head 52 and the water supply pipe 53 to press vertically downward. The tip of the water supply pipe 53 accurately inserts into the water inlet interface at the top of the control valve 100. At the same time, the sealing gasket one 522 is compressed and deformed to form an annular sealing layer on the interface flange surface, blocking the leakage between the water supply pipe 53 and the water supply pipe 53. The telescopic rod of the lower cylinder 51 drives the lower docking head 54 to vertically push upward, and the tip of the water outlet pipe 55 is embedded into the water outlet joint of the control valve 100. The sealing gasket two 542 fits the docking part of the water outlet pipe 55 and the control valve 100 after being pressed. At this time, the passages of the water supply pipe 53 and the water outlet pipe 55 are hermetically connected to the internal cavity of the control valve 100. Subsequently, multiple electric push rods 61 drive the lifting plate 62 to lift synchronously. The elastic sealing ring 641 at the top of the water receiving tank 64 and the sealing plate 56 at the bottom of the water outlet pipe 55 generate extrusion deformation, making the water receiving tank 64 and the water outlet pipe 55 hermetically connected. Subsequently, the flow rate detection program is carried out. According to the preset logic, the valve core of the control valve 100 is opened. At this time, the constant-pressure water flow in the water supply pipe 53 flows through the valve body cavity of the control valve 100 and then enters the water outlet pipe 55, and then is continuously injected into the water receiving tank 64 by the water outlet pipe 55. After the water injection process lasts for a period of time, the valve core of the control valve 100 is closed and the water supply of the water supply pipe 53 is stopped, so that the water flow is cut off in the control valve 100. Then, the air pump one 71 is started. The air pump one 71 sprays high-pressure air obliquely upward along the inner wall of the water outlet pipe 55 through the air pipe one 72 and the nozzle one 73. At this time, the high-pressure air cannot pass through the closed control valve 100 and can only flow down along the water outlet pipe 55. Thus, the air shear force is used to strip the water film attached to the inner wall of the water outlet pipe 55 and the outlet pipe wall of the control valve 100, forcing the residual water droplets in the water outlet pipe 55 to slide down along the pipe wall into the water receiving tank 64. The gas entering the water receiving tank 64 will be discharged from the exhaust valve 561, so that the water receiving tank 64 can fully collect the detected water volume. During this process, the humidity sensor 9 continuously monitors the humidity change of the pipe wall. When the detected humidity value drops to the critical threshold, the power supply of the air pump one 71 is automatically cut off by the controller. Finally, the electric push rod 61 drives the water receiving tank 64 to move down slowly, so that the water receiving tank 64 and the water outlet pipe 55 are separated. Then, the electronic scale 63 records the weight change of the current water receiving tank 64. By comparing the increment of the water flow weight with the increment of the timed control flow rate of the control valve 100, it is analyzed whether the actual flow rate control of the control valve 100 meets the standard, so as to judge the quality of the control valve 100.

[0034] Example 2: On the basis of Example 1, as Figure 1 , Figure 6 and Figure 7 shown, a drying mechanism 8 for the drying water receiving tank 64 is provided on the base frame 2. The drying mechanism 8 includes an air pump II 81 fixedly installed on the base frame 2. A heater 82 is installed on the base frame 2 near the air pump II 81. The air inlet of the air pump II 81 is connected to the heater 82 through a connecting pipe 83. A nozzle II 85 is installed at a lower position on the pipe wall of the water outlet pipe 55. The nozzle of the nozzle II 85 is inclined downward in the water outlet pipe 55. The air outlet of the air pump II 81 is communicated with an air pipe II 84. The air pump II 81 is connected to the nozzle II 85 through the air pipe II 84. Before replacing a new control valve 100 on the docking mechanism 5 for flow rate detection, after the electric push rod 61 drives the water receiving tank 64 to move downward and separate from the water outlet pipe 55, the water receiving tank 64 is removed from the bearing plate 631 of the electronic scale 63. After pouring out the water in the water receiving tank 64, the water receiving tank 64 is installed back on the bearing plate 631. The electric push rod 61 drives the water receiving tank 64 to be hermetically docked with the water outlet pipe 55. At this time, the air pump II 81 cooperates with the heater 82 to blow dry hot air into the water outlet pipe 55, so that the hot air can flow through the water outlet pipe 55 and then continuously enter the water receiving tank 64. After the hot air flows through the water receiving tank 64, it is discharged from the exhaust valve 561 on the sealing plate 56, thereby accelerating the drying of the water receiving tank 64 and avoiding the residual water in the water receiving tank 64 from affecting the subsequent flow rate detection of the control valve 100.

[0035] As Figure 1 , Figure 6 and Figure 9 shown, fastening mechanisms 11 are provided on both the upper docking head 52 and the lower docking head 54 of the docking mechanism 5. The fastening mechanism include fastening belts 111. Fastening belts 111 are wound around the peripheries of the sealing gasket I 522 and the sealing gasket II 542. The docking plate I 521 and the docking plate II 541 are both fixedly connected with a connecting rod I 112 and a connecting rod II 113. Motors 114 are fixedly installed on both the docking plate I 521 and the docking plate II 541. A driving roller 115 is fixedly installed on the output shaft of the motor 114. One end of the fastening belt 111 is fixedly connected to the connecting rod I 112. The other end of the fastening belt 111 bypasses the connecting rod II 113 and is connected to the driving roller 115. The motor 114 is used to drive the fastening belt 111 to tighten on the sealing gasket I 522 or the sealing gasket II 542, further ensuring the stability of the control valve 100 in docking the water supply pipe 53 and the water outlet pipe 55.

[0036] Before performing a flow rate detection on the next control valve 100, the operator first docks the newly tested control valve 100 to the docking mechanism 5, then removes the low-lying water receiving tank 64 from the bearing plate 631 of the electronic scale 63, pours out the stored water in the previous set of water receiving tanks 64, and reinstalls it on the bearing plate 631. Subsequently, the electric push rod 61 drives the water receiving tank 64 on the lifting plate 62 to be hermetically docked to the water outlet pipe 55 again. Then, the second air pump 81 and the heater 82 are activated. The second air pump 81 extracts the hot air that has been dried at high temperature from the heater 82 and injects it into the water outlet pipe 55 in the form of an inclined downward jet through the second nozzle 85. The hot air flow enters the water receiving tank 64 along the water outlet pipe 55 downward, and the dry hot gas is discharged through the one-way exhaust valve 561 on the sealing plate 56, forming a closed-loop drying cycle, so that the inner wall of the water receiving tank 64 quickly returns to a dry state. When the control valve 100 is docked to the water supply pipe 53 and the water outlet pipe 55, the motor 114 is activated. The motor 114 drives the driving roller 115 to rotate, and the driving roller 115 tightens the fastening belt 111 wound around the periphery of the sealing gasket. Through the transmission of the first connecting rod 112 and the second connecting rod 113, radial pressure is evenly applied to the interface flanges of the first sealing gasket 522 and the second sealing gasket 542, thereby eliminating the risk of micro-gap leakage between the docking interfaces caused by the manufacturing tolerances of the valve body.
