[0014] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0015] As Figs. 1 to 3 The utility model discloses a pressure release device for organic chemical industry, including connecting pipe 100, be equipped with valve ball 107 in connecting pipe 100, be equipped with a plurality of air holes 104 on the lateral wall of connecting pipe 100, the top of connecting pipe 100 is connected with sealing cover 103, the bottom outer wall of connecting pipe 100 is fixedly provided with mounting block 101, a plurality of mounting holes 102 are formed in mounting block 101, the inner wall of connecting pipe 100 is provided with limit groove 110, and limit block 109 is movably arranged in limit groove 110, and the lateral wall of limit block 109 is fixedly connected with valve ball 107.
[0016] through the mounting hole 102 on the mounting block 101, the pressure release device for organic chemical industry is fixedly installed on the chemical equipment or pipeline that needs, and the design of mounting block 101 makes the installation process simple and stable, is convenient for being connected with high pressure relief pipeline, according to actual needs, by rotating sealing cover 103 to adjust its position relative to connecting pipe 100, to ensure the sealing property of the device, the threaded connection between sealing cover 103 and connecting pipe 100 provides reliable sealing effect, when the internal pressure of chemical equipment or pipeline is normal, valve ball 107 is tightly attached to the inner wall of connecting pipe 100 under the action of gravity, prevents medium from leaking through air hole 104, ensures that medium does not leak out under normal working condition, when the internal pressure of chemical equipment or pipeline exceeds the set value, the pressure generated by medium to valve ball 107 overcomes its gravity, makes valve ball 107 move upwards under the guidance of limit groove 110 and limit block 109, to open air hole 104, and medium releases pressure through air hole 104, protects chemical equipment or pipeline from the damage of excessive pressure, sets up limit groove 110 and limit block 109, so that valve ball 107 moves more stably, enhances the stability of the device, and the pressure release device can respond to the excessive pressure in the chemical equipment or pipeline in time, prevents equipment damage or accident by releasing pressure, thereby improving production safety.
[0017] In the embodiment, the valve ball 107 is sleeved with a sealing ring 108, which is in close contact with the inside of the connecting pipe 100.
[0018] The sealing ring 108 on the valve ball 107 ensures the sealing of the device in the normal working state and prevents the leakage of the medium.
[0019] In the embodiment, the valve ball 107 is provided at the bottom with a connecting rope 106, and the bottom end of the connecting rope 106 is fixedly provided with a counterweight 105.
[0020] The counterweight 105 at the bottom of the valve ball 107 through the connecting rope 106 helps the valve ball 107 to quickly reset after pressure release, reduces the friction and wear of the valve ball 107 with the inner wall of the connecting pipe 100, and thus prolongs the service life of the device.
[0021] Working process and principle: when the device is used, the organic chemical pressure release device is fixedly installed on the required chemical equipment or pipeline through the multiple mounting holes 102 on the mounting block 101, and the position of the device relative to the connecting pipe 100 is adjusted by rotating the sealing cover 103 according to the actual needs, so as to ensure the sealing of the device. When the internal pressure of the chemical equipment or pipeline is normal, the valve ball 107 is tightly attached to the inner wall of the connecting pipe 100 under the action of gravity, preventing the leakage of the medium through the air hole 104, and the sealing ring 108 further enhances the sealing between the valve ball 107 and the connecting pipe 100, ensuring that the medium will not leak in the normal working state. When the internal pressure of the chemical equipment or pipeline exceeds the set value, the pressure of the medium on the valve ball 107 overcomes its gravity, so that the valve ball 107 moves upward under the guidance of the limiting groove 110 and the limiting block 109, thereby opening the air hole 104, and the medium is released through the air hole 104 to release the pressure, protecting the chemical equipment or pipeline from damage caused by excessive pressure. After the pressure is released, the valve ball 107 is quickly reset through the connecting rope 106 and the counterweight 105, reducing the friction and wear of the valve ball 107 with the inner wall of the connecting pipe 100. The pressure release device can timely respond to the excessive pressure inside the chemical equipment or pipeline, prevent the damage of the equipment or the occurrence of accidents by releasing the pressure, and thus improve the production safety.
