Description

Technical Field

[0001] This utility model relates to the field of gate valve testing technology, and in particular to a gate valve testing device. Background Technology

[0002] A gate valve is a gate that opens and closes. The direction of movement of the gate is perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed, and cannot be used for regulation or throttling. During the production process of gate valves, the semi-finished parts after the gate valve body and gate valve cover are assembled need to be tested for air tightness.

[0003] Chinese Patent Publication No. CN 219178853 U discloses an airtightness detection device for a gate valve, comprising a leakage detection mechanism and an inflation mechanism. A valve body is positioned between the leakage detection mechanism and the inflation mechanism. The leakage detection mechanism and the inflation mechanism are respectively fixedly connected to both sides of the valve body via mounting bolts. The inflation mechanism inflates and pressurizes the valve body, while the leakage detection mechanism detects leakage. This utility model relates to the field of gate valve technology. This airtightness detection device for a gate valve consists of two parts: a leakage detection mechanism and an inflation mechanism. The leakage detection mechanism and the inflation mechanism are respectively placed on both sides of the valve body and fixedly installed to the valve body via mounting bolts. The valve body is closed, and the inflation mechanism inflates one side of the valve body to a certain pressure. After a period of time, it determines whether there is a leakage, thus meeting the usage requirements.

[0004] The existing technical solutions mentioned above have the following shortcomings: Although the leakage detection mechanism and the inflation mechanism in the technical solutions have a basic connection method with the valve body, they are only suitable for valve bodies of a single size, and their scope of application is limited. There is room for optimization. Therefore, it is necessary to design a gate valve detection device to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gate valve detection device, comprising a gate valve body and a first detection seat, wherein the first detection seat is disposed on one side of the gate valve body;

[0007] Flanges are fixed on both sides of the gate valve body. A connecting plate is provided on the outer side of each flange, and a second detection seat is fixed on the outer side of the connecting plate. The second detection seat is composed of an outer combination seat and an inner combination seat.

[0008] The first detection seat is equipped with an air pump, and one end of the air pump is connected to the interior of the gate valve body through a connecting pipe. A control switch is provided at the top of the first detection seat. Connecting rings are fixed on the outer side of each connecting plate, and connecting threads are provided on the outer side of each connecting ring.

A display screen is connected to one end of the outer combination seat, and a microcontroller is installed inside the display screen.

[0009] When using a gate valve testing device based on this technical solution, a detachable connection structure is formed between the first and second testing seats and the connecting plate through the action of a connecting ring, connecting thread, and thread groove. This allows for the reduction of the floor space by splitting the device while replacing connecting plates of different sizes, making it easier to carry and meeting the testing needs of different scenarios.

[0010] Preferably, the connecting disc has uniformly spaced receiving grooves inside, and each receiving groove is rotatably connected to a threaded rod. Each threaded rod is threadedly connected to a threaded sleeve on its outer side, and the top of each threaded sleeve is connected to a fastening plate via a limiting block.

[0011] Preferably, the outer side of the connecting plate is uniformly connected with knobs, and the outer side of each knob is provided with anti-slip texture. The inner side of each knob extends into the receiving groove and is connected to the threaded rod.

[0012] Preferably, the connecting plate has uniformly spaced limiting grooves inside, and each limiting groove is movably connected to a limiting block.

[0013] Preferably, the inner side of each connecting plate is provided with a sealing gasket, and the sealing gasket is made of rubber.

[0014] Preferably, the output terminals of the control switch and the air pressure sensor are electrically connected to the input terminal of the microcontroller via wires, and the output terminal of the microcontroller is electrically connected to the input terminals of the air pump and the display screen via wires respectively.

[0015] Preferably, the fastening plates are provided in two sets, and each set has four plates.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the gate valve detection device realizes the function of portable detection and adjustment;

[0017] The device is equipped with a first and a second detection seat and operates by wiring and power supply. During use, the first and second detection seats are connected to the connecting plate through the action of connecting rings, connecting threads and thread grooves to form a detachable connection structure. This allows for easy replacement of different sized connecting plates according to the size of the gate valve body, while also reducing the footprint through the split design, making the device easy to carry and meet the testing needs of different scenarios. During the testing process, the first and second detection seats are respectively connected to the flanges on both sides of the gate valve body. The air pump is started by the control switch to supply air to one end of the gate valve body, while the other end is monitored by the air pressure sensor to detect the change in the flowing air pressure and the result is displayed on the screen for easy viewing by the staff.

[0018] By incorporating fastening plates into the aforementioned testing process, during the connection of the flange and connecting plate, rotating the knob drives the threaded rod to rotate. Under the action of the threaded connection, the threaded sleeve drives the fastening plates to move inward, allowing multiple sets of fastening plates to adhere to the flange and ensuring tight contact between the connecting plate and the flange. Furthermore, the sealing gasket between them effectively enhances the sealing performance of the connection, ensuring the smooth progress of the airtightness test. Attached Figure Description
