Description

Technical Field

[0001] This utility model relates to the technical field of portable filter pressure relief observers, and particularly to portable filter pressure relief observers. Background Technology

[0002] In oil depot operations, the oil vent valve and safety valve on the top of the filter may experience pressure build-up due to oil filling after filter maintenance or significant temperature changes. Some oil may be discharged from the pressure relief pipeline to the recovery unit. Currently, the pressure relief pipeline uses a standard glass sight glass to observe whether the pipeline is overflowing with oil. This method has drawbacks such as the glass being fragile, difficult to disassemble, and poor sealing between the glass tube and the gaskets at both ends. When discharging moisture and impurities from the filter, the process system connected to the pressure relief pipeline on the top of the filter may experience backflow of oil due to excessive discharge flow rate and pressure, causing oil leakage from the sight glass. Furthermore, during maintenance, employees may easily apply excessive force, causing the glass to crack at both ends, or apply insufficient force, resulting in an incomplete seal. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a portable filter pressure relief observation device, which solves the problems of poor sealing, fragile glass, oil backflow, and difficult maintenance of existing sight glasses, thereby increasing process safety and the convenience of equipment maintenance.

[0004] This utility model provides a portable filter depressurization observation device, including a sight glass. The outlet of the sight glass is equipped with a one-way valve to prevent oil backflow. The bottom of the sight glass is equipped with a portable vent valve to facilitate timely venting after the filter depressurizes, without affecting the next observation.

[0005] Preferably, the peephole is integrally cast from steel.

[0006] Preferably, the end of the viewing mirror is provided with mounting flanges.

[0007] Preferably, the sight glass is mounted on the oil passage pipe.

[0008] Preferably, the viewing mirror includes an inlet, an outlet, and a high-transparency explosion-proof glass disposed between the inlet and the outlet.

[0009] Preferably, the high-transparency explosion-proof glass is disposed on the front and rear sides.

[0010] Beneficial effects of this utility model

[0011] This utility model provides a portable filter pressure relief observation device, which includes a viewing mirror, a one-way valve, and a bottom drain valve. The viewing mirror is made of cast steel in one piece, and high-transparency explosion-proof glass is installed on the front and rear sides. The viewing mirror outlet is equipped with a one-way valve to prevent oil backflow. The bottom of the viewing mirror is equipped with a portable vent valve, which facilitates timely venting after the filter is depressurized, without affecting the next observation.

[0012] This invention improves safety, convenience, and economy.

[0013] Safety: The integrated explosion-proof glass sealing structure greatly reduces the risk of oil leakage, and the one-way valve prevents oil backflow that could cause the sight glass to leak.

[0014] Convenience: It is easier to disassemble and replace equipment during maintenance and replacement.

[0015] Economic efficiency: Compared to the original equipment, which frequently requires replacement of damaged sights glass tubes, the explosion-proof glass and other components have a longer service life. Attached Figure Description
