Description

Technical Field

[0001] The utility model relates to the technical field of water pressure switch production, in particular to a production detection device for plastic water pressure switches. Background Art

[0002] The water pressure differential switch is a kind of water flow switch. It measures the pressure drop at both ends of valves, orifice plates, etc., and then obtains the accurate flow rate by referring to the pressure drop and flow rate curves of the valves or orifice plates. Compared with the target flow switch, it can avoid false flow caused by pump cavitation, and has very accurate reset flow rate and cut-off flow rate. Therefore, it can be widely used in large, medium and small air-cooled or water-cooled chillers using plate heat exchangers, shell-and-tube heat exchangers, and shell-and-tube heat exchangers for water flow control and monitoring the status of water pumps and water filters.

[0003] During the production process of water pressure switches, it is necessary to conduct sampling quality inspections on water pressure switches to ensure that unqualified water pressure switches do not leave the factory, and to collect and accumulate data reflecting the quality status. Therefore, a production detection device for plastic water pressure switches is proposed. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a production detection device for plastic water pressure switches. By setting a water pump and a pressure reducing valve to convey high-pressure water flow and low-pressure water flow to the plastic water pressure switches, the problems in the background art can be effectively solved.

[0005] To achieve the above purpose, the utility model provides a production detection device for plastic water pressure switches, which includes a workbench, a first detection mechanism, a second detection mechanism, and an intermittent motion mechanism;

[0006] Two detection brackets are arranged on one side of the workbench, and the two detection brackets are used to place plastic water pressure switches;

[0007] The first detection mechanism includes a water pump and an intermittent motion mechanism, and the intermittent motion mechanism is used to drive the water pump to perform linear reciprocating intermittent motion;

[0008] The second detection mechanism includes a pressure reducing valve and an intermittent motion mechanism, and the intermittent motion mechanism is used to drive the pressure reducing valve to perform linear reciprocating intermittent motion;

[0009] There are two intermittent motion mechanisms, and the two intermittent motion mechanisms are respectively connected to the water pump and the pressure reducing valve. The intermittent motion mechanism includes a driving component, a sliding guide rail, and a transmission plate. The sliding guide rail is installed on the workbench. An arc-shaped guide groove is formed on the transmission plate. Two sliding rods are respectively fixedly connected to both sides of the transmission plate, and the two sliding rods are respectively slidably installed in the sliding guide rail. The driving component is used to drive the transmission plate to perform linear reciprocating intermittent motion.

[0010] On the basis of the above technical solutions, the following improvements can be further made to the present utility model.

[0011] Further, the driving assembly includes a driving motor, a rotating disk, and a transmission block. The driving motor is installed on the workbench. The rotating disk is located on one side of the transmission plate, and the output shaft of the driving motor is connected to the central position of the rotating disk. A transmission block is connected to the outer edge of one side of the rotating disk, and the transmission block is slidably installed in the arc-shaped guide groove.

[0012] Further, both ends of the arc-shaped guide groove extend outward in a direction perpendicular to the sliding rod.

[0013] Further, a collection pool is provided on the side of the plastic water pressure switch away from the intermittent motion mechanism.

[0014] Further, when the transmission plate moves to the side close to the plastic water pressure switch, the movement trajectory of the transmission block coincides with the trajectory of the arc-shaped guide groove.

[0015] The beneficial effects of the present utility model are as follows: The present utility model provides a production detection device for plastic water pressure switches, having the following advantages:

[0016] In the present utility model, by providing a water pump and a pressure reducing valve that perform linear reciprocating intermittent motion, taking the pressure reducing valve as an example, when the transmission block rotates towards the direction close to the plastic water pressure switch, the transmission block drives the transmission plate to move towards the direction close to the plastic water pressure switch, thereby driving the pressure reducing valve to move towards the direction close to the plastic water pressure switch. When the pressure reducing valve moves to the side close to the plastic water pressure switch, the pressure reducing valve is connected to the plastic water pressure switch. And when the transmission plate moves to the side close to the plastic water pressure switch, the movement trajectory of the transmission block coincides with the trajectory of the arc-shaped guide groove. At this time, the pressure reducing valve and the plastic water pressure switch are in a connected state. Thus, within the movement time period when the movement trajectory of the transmission block coincides with the trajectory of the arc-shaped guide groove, the pressure reducing valve is in a stationary state. When the pressure reducing valve is in a stationary state, the pressure reducing valve conveys low-pressure water flow to the plastic water pressure switch, thereby detecting whether the plastic water pressure switch can automatically close when encountering too low water pressure. By sequentially inputting high-pressure water flow and low-pressure water flow to the plastic water pressure switch, the quality detection of the plastic water pressure switch is completed.

[0027] This utility model provides a production detection device for plastic water pressure switches, which includes a workbench 1, a first detection mechanism 4, a second detection mechanism 5, and an intermittent motion mechanism 6;

[0028] As Figure 1 shown, two detection brackets 2 are provided on one side of the workbench 1, and the two detection brackets 2 are used to place the plastic water pressure switch 3. A collection pool 17 is provided on the side of the plastic water pressure switch 3 away from the intermittent motion mechanism 6, and the collection pool 17 is used to collect the waste liquid generated after detection;

[0029] As Figure 1 shown, the first detection mechanism 4 includes a water pump 7 and an intermittent motion mechanism 6. The water pump 7 is connected to an external water source, and the water pump 7 is used to generate high-pressure water flow. The intermittent motion mechanism 6 is used to drive the water pump 7 to perform linear reciprocating intermittent motion. The second detection mechanism 5 includes a pressure reducing valve 8 and an intermittent motion mechanism 6. The pressure reducing valve 8 is connected to an external water source, and the pressure reducing valve 8 is used to generate low-pressure water flow. The intermittent motion mechanism 6 is used to drive the pressure reducing valve 8 to perform linear reciprocating intermittent motion;

[0030] As Figures 1-3 shown, there are two intermittent motion mechanisms 6, and the two intermittent motion mechanisms 6 are respectively connected to the water pump 7 and the pressure reducing valve 8. The intermittent motion mechanism 6 includes a driving component 9, a sliding guide rail 10, and a transmission plate 11. The sliding guide rail 10 is installed on the workbench 1. An arc-shaped guide groove 12 is provided on the transmission plate 11. The two ends of the arc-shaped guide groove 12 extend outward in a direction perpendicular to the sliding rod 13. Two sliding rods 13 are respectively and fixedly connected to both sides of the transmission plate 11, and the two sliding rods 13 are respectively slidably installed in the sliding guide rail 10. The driving component 9 is used to drive the transmission plate 11 to perform linear reciprocating intermittent motion;

[0031] As Figures 2-3 shown, the driving component 9 includes a driving motor 14, a rotating disk 15, and a transmission block 16. The driving motor 14 is installed on the workbench 1. The rotating disk 15 is located on one side of the transmission plate 11, and the output shaft of the driving motor 14 is connected to the center position of the rotating disk 15. A transmission block 16 is connected to the outer edge of one side of the rotating disk 15, and the transmission block 16 is slidably installed in the arc-shaped guide groove 12;

[0032] In this embodiment, the transmission block 16 makes a circular motion with the output shaft of the driving motor 14 as the rotation axis. When the transmission block 16 rotates away from the plastic water pressure switch 3, the transmission block 16 drives the transmission plate 11 to move away from the plastic water pressure switch 3, thereby driving the water pump 7 or the pressure reducing valve 8 to move away from the plastic water pressure switch 3. When the transmission block 16 rotates towards the plastic water pressure switch 3, the transmission block 16 drives the transmission plate 11 to move towards the plastic water pressure switch 3, thereby driving the water pump 7 or the pressure reducing valve 8 to move towards the plastic water pressure switch 3. When the water pump 7 and the pressure reducing valve 8 move to the side close to the plastic water pressure switch 3, the water pump 7 and the pressure reducing valve 8 are connected to the plastic water pressure switch 3;

[0033] As Figure 4 shown, when the transmission plate 11 moves to the side close to the plastic water pressure switch 3, the movement trajectory of the transmission block 16 coincides with the trajectory of the arc-shaped guide groove 12. At this time, the water pump 7 or the pressure reducing valve 8 is in a connected state with the plastic water pressure switch 3. Therefore, within the movement time period when the movement trajectory of the transmission block 16 coincides with the trajectory of the arc-shaped guide groove 12, the water pump 7 or the pressure reducing valve 8 is in a stationary state. When the water pump 7 or the pressure reducing valve 8 is in a stationary state, the water pump 7 or the pressure reducing valve 8 conveys high-pressure water flow or low-pressure water flow to the plastic water pressure switch 3, so as to detect whether the plastic water pressure switch 3 can automatically close when encountering too high water pressure or too low water pressure, thereby completing the quality inspection of the plastic water pressure switch 3.

[0034] The working principle is as follows:

[0035] The staff sequentially place the plastic water pressure switch 3 on two detection brackets 2. Taking the pressure reducing valve 8 as an example, the driving motor 14 drives the rotating disk 15 to rotate, and then drives the transmission block 16 to perform circular motion with the output shaft of the driving motor 14 as the rotation axis. When the transmission block 16 rotates towards the direction close to the plastic water pressure switch 3, the transmission block 16 drives the transmission plate 11 to move towards the direction close to the plastic water pressure switch 3, and then drives the pressure reducing valve 8 to move towards the direction close to the plastic water pressure switch 3. When the pressure reducing valve 8 moves to the side close to the plastic water pressure switch 3, the pressure reducing valve 8 is connected to the plastic water pressure switch 3. When the transmission plate 11 moves to the side close to the plastic water pressure switch 3, the movement trajectory of the transmission block 16 coincides with the trajectory of the arc-shaped guide groove 12. At this time, the pressure reducing valve 8 and the plastic water pressure switch 3 are in a connected state. Thus, within the movement time period when the movement trajectory of the transmission block 16 coincides with the trajectory of the arc-shaped guide groove 12, the pressure reducing valve 8 is in a stationary state. When the pressure reducing valve 8 is in a stationary state, the pressure reducing valve 8 conveys low-pressure water flow to the plastic water pressure switch 3, so as to detect whether the plastic water pressure switch 3 can automatically close when encountering too low water pressure. When the transmission block 16 rotates towards the direction away from the plastic water pressure switch 3, the transmission block 16 drives the transmission plate 11 to move towards the direction away from the plastic water pressure switch 3, and then drives the pressure reducing valve 8 to move towards the direction away from the plastic water pressure switch 3. Then the pressure reducing valve 8 is disconnected from the plastic water pressure switch 3. By sequentially inputting high-pressure water flow and low-pressure water flow to the plastic water pressure switch 3, the quality detection of the plastic water pressure switch 3 is completed.
