Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve structure with a protective structure. Background Art

[0002] Valves are very important control devices in pipeline systems. Their main function is to control and regulate the flow, pressure and direction of fluids. Valves are widely used in the fields of petroleum, chemical industry, water treatment, food, medicine, metallurgy, energy, etc. Valves play an important role in various industrial production and daily life, ensuring the safety and stable operation of the system.

[0003] Valves are generally exposed to the outside air, and there is no anti-impact protective structure on the outside. Therefore, they are easily damaged by various external factors. When the valve is damaged, leakage is likely to occur at the connection. In addition, it is impossible to issue an early warning after the valve leaks, which brings great inconvenience to maintenance and repair work.

[0004] In order to solve the above problems, the present application proposes a valve structure with a protective structure. Utility Model Content

[0008] The outer periphery of the valve body is detachably provided with two arc covers fitting each other, the ends of the two arc covers are both provided with arc blocks fitting on the outer periphery of the shaft tube, the two arc blocks fit each other, the sides of the arc blocks are provided with through openings, and the openings are connected with leakage pressure alarm components.

[0009] Preferably, the leakage pressure alarm component includes a pressure tube, which is connected to the opening. A cavity is opened in the pressure tube, and a partition plate is installed in the cavity. The partition plate divides the cavity into an inlet chamber and an assembly chamber. The inlet chamber is connected to the opening, and an elastic part located in the inlet chamber is passed through the partition plate, and a pressure alarm part is installed in the assembly chamber.

[0010] Preferably, the elastic part includes a connecting rod, a piston and a spring, a through hole is opened in the separating plate, the connecting rod slides through the through hole, the piston is connected to one end of the connecting rod and is located in the inlet chamber, the spring is sleeved on the connecting rod and is located between the separating plate and the piston, and the two ends of the spring are respectively connected to the separating plate and the piston.

[0011] Preferably, the pressure alarm unit comprises a pressure sensor and a buzzer, the pressure sensor is installed in the assembly chamber, the buzzer is installed at one end of the pressure tube away from the arc block, and the pressure sensor is electrically connected to the buzzer.

[0012] Preferably, a fixing block is installed on each of the two arc-shaped covers, bolts are threadedly connected to the two fixing blocks, and a nut that abuts against one of the fixing blocks is threadedly sleeved on the bolts.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] By providing an arc cover, an arc block and a leakage pressure alarm, the arc cover can be used to protect the periphery of the valve body to prevent the valve body from being damaged by external forces. When a leak occurs at the connection of the valve body, the leaked fluid can enter the leakage pressure alarm through the opening in the arc block, and under the action of pressure, an alarm is triggered to serve as a reminder. This structure protects the periphery of the valve body through the arc cover, which can effectively prevent the valve body from being damaged by external forces, and can promptly issue an early warning when a leak occurs in the valve body, reminding relevant personnel to perform maintenance and repairs, thereby reducing the inconvenience and potential risks caused by leakage problems.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] like Figure 1-3 As shown, the utility model provides a valve structure with a protective structure, including a valve body 1;

[0021] In this embodiment, the water inlet end and the water outlet end of the valve body 1 are both connected to the shaft tube 2.

[0022] In this embodiment, the outer periphery of the valve body 1 is detachably covered with two mutually fitting arc covers 3, and the ends of the two arc covers 3 are both installed with arc blocks 4 fitted on the outer periphery of the shaft tube 2, and the two arc blocks 4 are fitted with each other, and the side of the arc blocks 4 is provided with a through opening, and the opening is connected with a leakage pressure alarm 5. The leakage pressure alarm 5 includes a pressure pipe 51, which is connected to the opening, and a cavity is provided in the pressure pipe 51, and a separation plate 52 is installed in the cavity, and the separation plate 52 separates the cavity into an inflow chamber and an assembly chamber, and the inflow chamber is connected to the opening, and an elastic part 53 located in the inflow chamber is penetrated on the separation plate 52, and a pressure alarm part 54 is installed in the assembly chamber. The elastic part 53 includes a connecting rod 531, a piston 532 and a spring 533. A through hole is provided in the partition plate 52. The connecting rod 531 slides through the through hole. The piston 532 is connected to one end of the connecting rod 531 and is located in the inlet chamber. The spring 533 is sleeved on the connecting rod 531 and is located between the partition plate 52 and the piston 532. The two ends of the spring 533 are respectively connected to the partition plate 52 and the piston 532. The pressure alarm part 54 includes a pressure sensor 541 and a buzzer 542. The pressure sensor 541 is installed in the assembly chamber. The buzzer 542 is installed at one end of the pressure tube 51 away from the arc block 4. The pressure sensor 541 and the buzzer 542 are electrically connected.

[0023] It should be noted that: in order to be able to give a timely warning when the valve body 1 leaks, the arc cover 3 can be used to protect the periphery of the valve body 1 to prevent the valve body 1 from being damaged by external forces. When a leak occurs at the connection of the valve body 1, the leaked fluid can enter the pressure tube 51 through the opening formed in the arc block 4, pushing the piston 532 to move in the pressure tube 51, and the spring 533 is compressed. The connecting rod 531 connected to the piston 532 approaches the pressure sensor 541. When the connecting rod 531 abuts against the pressure sensor 541, the pressure signal received by the pressure sensor 541 is immediately transmitted to the buzzer 542, and an alarm can be issued through the buzzer 542 to serve as a reminder. The structure protects the periphery of the valve body 1 through the arc cover 3, which can effectively prevent the valve body 1 from being damaged by external forces, and can give a timely warning when the valve body 1 leaks, reminding relevant personnel to perform maintenance and repairs, thereby reducing the inconvenience and potential risks caused by leakage problems.

[0024] In the specific embodiment, the two arc-shaped covers 3 are both mounted with fixing blocks 6 , the two fixing blocks 6 are threadedly penetrated with bolts 7 , and the bolts 7 are threadedly sleeved with nuts 8 that abut against one of the fixing blocks 6 .

[0025] It should be noted that: in order to facilitate the disassembly and assembly of the arc cover 3 on the periphery of the valve body 1, it is only necessary to thread the bolt 7 through the fixing blocks 6 on the two arc covers 3, and then put the nut 8 on the bolt 7, and abut the nut 8 against one of the fixing blocks 6 to complete the installation. When disassembling, it is only necessary to unscrew the nut 8 from the bolt 7. This structure facilitates the disassembly and assembly of the arc cover 3 on the periphery of the valve body 1.
