Description

Technical Field

[0001] This utility model belongs to the field of diaphragm pump ball valve blockage detection technology, and more specifically, it relates to a diaphragm pump check valve jamming fault alarm device. Background Technology

[0002] Slurry pipeline transportation is a transportation method consisting of large steel pipes, pumping stations, and pressurization equipment. It has advantages such as continuity, safety, reliability, economy, and environmental protection. It is especially suitable for situations where road traffic is inconvenient, materials are prone to spillage or leakage, and it is developing towards large diameter, long distance, high pressure, and automation. In recent years, pipeline transportation has developed rapidly, but safety and stability are accompanying problems that urgently need to be solved.

[0003] Diaphragm pumps are the power equipment for slurry pipeline transportation and the core pressurizing equipment for pipeline transportation. Therefore, the safe and stable operation of diaphragm pumps is a core issue in pipeline transportation. The safe operation of diaphragm pumps can ensure the continuous and stable operation of pipeline transportation and improve the production efficiency of enterprises. Once a diaphragm pump fails, the slurry pipeline may stop with slurry, and the sedimentation of solid slurry may cause pipeline blockage and high-pressure pipe bursts, resulting in serious production accidents and losses. Therefore, real-time status monitoring and fault diagnosis of diaphragm pumps are crucial to the production efficiency and safety of metallurgical enterprises. However, existing diaphragm pumps have corresponding ball valves inside the circulation pipe to act as one-way valves. Since the ball valve needs to move up and down through the fluid inside the valve to control the opening and closing of the pipeline, the flow status of the ball valve is crucial. However, the existing ball valves in diaphragm pumps lack an effective detection structure for the flow status of the ball valve during operation. This makes it easy for the fluid to backflow and damage the diaphragm pump when the ball valve is not completely reset, which has limitations. Utility Model Content

This device solves the problem that existing diaphragm pumps lack an effective detection structure for the flow status of the ball valve during operation, which makes it easy for fluid to backflow and damage the diaphragm pump when the ball valve is not completely reset, thus presenting limitations.

[0005] The purpose and effectiveness of this utility model's one-way valve jamming fault alarm device for diaphragm pumps are achieved through the following specific technical means:

[0006] A diaphragm pump check valve jamming alarm device includes a conduit. The main body of the conduit is a U-shaped tube structure, and the conduit is used to connect to the diaphragm pump body. A flange is fixedly connected to the bottom end face of the conduit. There are two flanges, and the two flanges are respectively fixedly connected to the bottom end faces of two longitudinal members of the conduit. The conduit and the flange are in communication. The diameter of the flange is larger than the diameter of the conduit. The flange and the conduit together form a connection structure.

[0007] Furthermore, the flange has through holes inside, which are mounting holes. Each flange has six mounting holes arranged in a ring array inside, and the mounting holes and the flange together form a connection structure.

[0010] Furthermore, there are two warning lights, one on the left and one on the right side of the front face of the controller. Each warning light is matched with a longitudinal member on the left or right side of the conduit. A baffle is fixedly connected inside the conduit. The baffle has a ring-shaped structure and there are four baffles in total. Each pair of longitudinally adjacent baffles forms a group, and the two groups of baffles are installed inside the two longitudinal members of the conduit. A crossbeam is fixedly connected inside each group of baffles. The crossbeam and the baffle together form a detection structure. A detection component is fixedly connected to the inner side of the crossbeam. Two ball valves are installed inside the conduit, one inside the two longitudinal members at the bottom of the conduit and the other inside the two groups of baffles. The detection component detects the current position of the ball valve inside the conduit. The ball valve is magnetic.

[0011] Furthermore, the front surface of the controller is a protruding front end face structure of the conduit, and a buzzer is fixedly connected to the front end face of the controller.

There are two warning lights 8, and the two warning lights 8 are respectively installed on the left and right sides of the front face of the controller 6, and the two warning lights 8 are matched with the left and right longitudinal components of the conduit 1. A baffle is fixedly connected inside the conduit 1. 9. The main body of the baffle 9 is a ring structure, and there are four baffles 9 in total. Each pair of longitudinally adjacent baffles 9 forms a group, and the two groups of baffles 9 are respectively installed on the inner side of two longitudinal members in the conduit 1. The interior of each group of baffles 9 is fixedly connected to a crossbeam 10. The crossbeam 10 and the baffle 9 together form a detection structure. The inner side of the crossbeam 10 is fixedly connected to a detection component 11. The conduit 1 is equipped with a ball valve 12. There are two ball valves 12, and the two ball valves 12 are respectively located on the inner side of two longitudinal members at the bottom end of the conduit 1. The two ball valves 12 are respectively located on the inner side of the two groups of baffles 9. The current position of the ball valve 12 inside the conduit 1 is detected by the detection component 11. The ball valve 12 is magnetic.

[0026] The flange 2 has a through hole inside, which is a mounting hole 3. Each flange 2 has six mounting holes 3 arranged in a ring array inside. The mounting holes 3 and the flange 2 together form a connection structure. A base plate 4 is fixedly connected to the rear side of the transverse component in the conduit 1. The main body of the base plate 4 has an arc-shaped structure at all four corners of its outer side, and the base plate 4 has a through hole inside, which is a fixing hole 5.

[0027] There are four fixing holes 5, which are respectively opened at the four corners of the substrate 4. The fixing holes 5 are used for bolt assembly. The fixing holes 5 and the substrate 4 together form a connection structure. The front end face of the transverse component in the conduit 1 is provided with a groove.

[0030] Furthermore, once the conduit 1 is assembled, the detection component 11 can be energized. Since the ball valve 12 inside the conduit 1 moves up and down with the movement of the fluid, the proximity of the ball valve 12 can be detected by the detection component 11 installed in the crossbeam 10. When the ball valve 12 is detected to be incompletely reset, the feedback can be synchronously sent to the controller 6, and the buzzer 7 installed on the front face of the controller 6 can be activated synchronously to quickly sound an alarm.

[0032] Based on the detection component 11 provided in Embodiment 1, the detection component 11 can be used by employing a Hall element. When the detection component 11 is used by employing a Hall element, the movement of the ball valve 12 can be detected by assembling the detection component 11 into the internal position of the crossbeam 10 fixedly connected in the baffle 9, thereby achieving a more practical purpose.

[0033] Example 3:

[0034] Based on the baffle 9 provided in Embodiment 1, the side of the baffle 9 near the ball valve 12 can be used by setting a corresponding rubber layer on its surface. When the rubber layer is set on the opposite surface of the baffle 9, the wear between the workpieces can be reduced by using the rubber layer when the ball valve 12 moves toward one side of the baffle 9.
