Description

Technical Field

[0001] This utility model relates to the field of pressure vessel technology, specifically to a pressure vessel with a pressure detection structure. Background Technology

[0002] A pressure vessel is a sealed device that holds gas or liquid under pressure. To more effectively implement scientific management and safety supervision, my country's "Safety Supervision Regulations for Pressure Vessels" classifies pressure vessels into three categories based on working pressure, the hazard of the medium, and its role in production. Different regulations are made for the design, manufacturing process, inspection items, contents, and methods for each category of pressure vessels. To monitor the status of pressure vessels in real time, a pressure vessel with a pressure detection structure is needed.

[0003] The existing patent, CN215950356U, entitled "High-Pressure Resistant Pressure Vessel," discloses a high-pressure resistant pressure vessel comprising an air bladder and a mounting frame. The mounting frame is located on the upper left side of the air bladder, and an air replenishment device is located on the right side of the mounting frame. A T-junction is located on the right side of the air replenishment device, with a pressure gauge at the upper end of the T-junction and a pressure switch to the right of the pressure gauge. A water storage tank is located at the lower end of the air bladder, with an inlet on the upper left side and an outlet on the lower right side. This utility model uses the air replenishment device to supply air to the air bladder. When the water level in the water storage tank is high, the air bladder will supply excess air to the air storage cylinder through the T-junction. When the water level in the water storage tank drops, the air replenishment device uses a spring to re-transport air into the air bladder, ensuring a continuous supply of air in the air bladder, reducing subsequent maintenance, and greatly enhancing the practicality of the pressure vessel.

[0004] The aforementioned device uses an air supply device to deliver air to the air storage bladder. When there is a large amount of water in the water storage tank and the internal pressure is too high, the air storage bladder will deliver the excess air to the air storage cylinder through the three-way valve. However, the device lacks a pressure detection structure, so the staff cannot monitor the working status of the device in real time and cannot well meet people's usage needs. In view of the above situation, technical innovation is carried out on the basis of existing pressure vessels. Utility Model Content

[0005] The purpose of this invention is to provide a pressure vessel with a pressure detection structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure vessel with a pressure detection structure, comprising a shell and an outer shell, wherein a front cover is installed below the front end of the shell and is rotatably connected to the shell, the outer shell is installed above the front end of the shell and is welded to the shell, and a piston is slidably connected to the left side inside the outer shell, and a spring rod is installed at the rear end of the piston.

[0007] Furthermore, a sensing component is installed on the right side of the piston, and the sensing component is embedded in the piston. A through hole is provided on the left side of the outer casing to connect with the outside.

[0008] Furthermore, the sensing component includes a conductive block, a contact, and a sensor, with the contact located on the right side of the conductive block and the sensor mounted on the right side of the contact.

[0009] Furthermore, a transmitter is installed on the right side of the sensor, and a buzzer is installed on one side of the transmitter. The transmitter sends maintenance information to the staff, and at the same time the buzzer sounds to remind non-professionals in the vicinity to stay away.

[0010] Furthermore, an observation window is installed inside the front cover, and a handle is installed at the front end of the front cover. The observation window on the front cover facilitates observation of the internal situation, and the handle facilitates opening the front cover.

[0011] Furthermore, a discharge port is installed at the lower center of the housing, and a support leg is installed on the lower outer side of the housing. The support leg can be fixed to the ground by expansion bolts or the like to prevent tipping. The discharge port at the bottom facilitates material discharge.

[0012] Furthermore, a connecting pipe is installed on the left side of the housing, and a flange is installed on the left side of the connecting pipe. The flange is used to connect external pipes or other equipment to ensure sealing. The connecting pipe with a nominal diameter ≥ mm is a major pressure-bearing component.

[0013] Furthermore, a pressure relief valve is installed on the right side of the housing, and the pressure relief valve is threadedly connected to the housing. The device can quickly release pressure through the pressure relief valve, which facilitates maintenance.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the flange is used to connect external pipes or other equipment to ensure sealing; the pipe with a nominal diameter ≥250mm is the main pressure-bearing component; the observation window on the front cover facilitates observation of the internal situation; the handle makes it easy to open the front cover; the support feet can be fixed to the ground by expansion bolts to prevent tipping; the discharge port at the bottom facilitates material discharge; when the pressure rises, the pressure pushes the piston to move, and the spring rod resists the piston's movement; when the pressure exceeds the safe range, the piston moves to the contact position, and the conductive block connects the two contacts; after the sensor detects the pressure, the transmitter sends maintenance information to the staff, and at the same time the buzzer sounds to remind non-professionals to stay away; the device can quickly release pressure through the pressure relief valve for easy maintenance.

[0015] 1. When the pressure rises, the pressure pushes the piston to move, and the spring rod hinders the piston's movement. When the pressure exceeds the safe range, the piston moves to the contact position, and the conductive block connects the two contacts. After the sensor detects this, the transmitter sends maintenance information to the staff, and at the same time, the buzzer sounds to remind non-professionals in the vicinity to stay away. The device can quickly release pressure through the pressure relief valve, which is convenient for maintenance.

[0016] 2. This utility model uses flanges to connect external pipes or other equipment to ensure sealing. Pipes with a nominal diameter of ≥250mm are the main pressure-bearing components. The observation window on the front cover facilitates observation of the internal situation. The handle makes it easy to open the front cover.

[0021] like Figure 1 and Figure 2As shown, a pressure vessel with a pressure detection structure includes a shell 1 and an outer shell 9. A front cover 6 is installed below the front end of the shell 1 and is rotatably connected to the shell 1. The outer shell 9 is installed above the front end of the shell 1 and is welded to the shell 1. A piston 10 is slidably connected to the left side of the interior of the outer shell 9, and a spring rod 11 is installed at the rear end of the piston 10. A sensing component 12 is installed on the right side of the piston 10 and is embedded in the piston 10. The sensing component 12 includes a conductive block 1201, a contact 1202, and a sensor 1203. The contact 1202 is located on the right side of the conductive block 1201. A sensor 1203 is installed on the right side of point 1202, and a transmitter 13 is installed on the right side of sensor 1203. A buzzer 14 is installed on one side of transmitter 13. When the pressure rises, the pressure pushes piston 10 to move. Spring rod 11 hinders piston 10 from moving. When the pressure exceeds the safe range, piston 10 moves to contact point 1202. Conductive block 1201 connects the two contacts 1202. After sensor 1203 detects the pressure, transmitter 13 sends maintenance information to the staff. At the same time, buzzer 14 sounds to remind non-professionals to stay away. The device can quickly release pressure through pressure relief valve 15 for easy maintenance.

[0022] like Figure 3 As shown, the front cover 6 has an observation window 7 installed inside, and a handle 8 installed at the front end of the front cover 6. The discharge port 3 is installed in the lower middle part of the housing 1, and the support leg 2 is installed on the lower outer side of the housing 1. The pipe 4 is installed on the left side of the housing 1, and a flange 5 is installed on the left side of the pipe 4. The pressure relief valve 15 is installed on the right side of the housing 1, and the pressure relief valve 15 is threaded to the housing 1. The flange 5 is used to connect to external pipes or other equipment to ensure sealing. The pipe 4 with a nominal diameter ≥250mm is a major pressure-bearing component. The observation window 7 on the front cover 6 facilitates observation of the internal situation. The handle 8 facilitates opening the front cover 6. The support leg 2 can be fixed to the ground by expansion bolts, etc., to prevent tipping. The discharge port 3 at the bottom facilitates material discharge.

[0023] Working principle: When using this pressure vessel with a pressure detection structure, firstly, the flange 5 is used to connect external pipes or other equipment to ensure sealing. The pipe 4 with a nominal diameter ≥250mm is the main pressure-bearing component. The observation window 7 on the front cover 6 facilitates observation of the internal situation. The handle 8 makes it easy to open the front cover 6. The support legs 2 can be fixed to the ground with expansion bolts to prevent tipping. The discharge port 3 at the bottom facilitates material discharge. When the pressure rises, the pressure pushes the piston 10 to move. The spring rod 11 hinders the movement of the piston 10. When the pressure exceeds the safe range, the piston 10 moves to the contact point 1202. The conductive block 1201 connects the two contacts 1202. After the sensor 1203 detects the pressure, the transmitter 13 sends a maintenance message to the staff. At the same time, the buzzer 14 sounds to remind non-professionals to stay away. The device can quickly release pressure through the pressure relief valve 15 for easy maintenance.
