Example Embodiment

[0017] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The emergency shut-off valve comprehensive verification system of the present invention is composed of a pipeline system, a clamping platform, an inspection operation platform, and a control system. Such as figure 1 As shown, the operation process of the calibration system is as follows: before the calibration operation starts, the integrity of the inspection platform is checked and the emergency shut-off valve is clamped on the clamping platform to ensure that the shut-off valve is installed securely and the system is calibrated. The verification conditions are ready and the verification operation is started. The verification sequence is: tightness verification, pressure resistance verification, cut-off ...

Abstract

The invention relates to an integrated check system for an emergency cut-off valve. The integrated check system comprises a pipe system, a clamping platform, a check operation platform and a control system, wherein the pipe system comprises a gas path pipe and a waterway pipe; a gas path DN15 and a waterway DN50 flange interface is arranged at an inlet of the check operation platform; one DN50 outlet is shared by an outlet gas path and an outlet waterway in a mixed manner and is connected with the camping platform; the clamping platform is used for clamping the to-be-checked emergency cut-off valve, wherein a gas path part is used for checking the air-tightness and the pressure resistance of the emergency cut-off valve; a waterway part is used for checking cut-off time and overcurrent cut-off of the emergency cut-off valve and circulating water is adopted; and the control system is used for completing operation control by adopting a PLC; all check work is completed on the operation platform, so that automatic check work can be achieved, the check work can be manually controlled through components on the operation platform, and a monitoring management center can record and display all check operation states in real time.

Description

technical field [0001] The invention relates to an automatic calibration system, in particular to a comprehensive calibration system for an emergency cut-off valve. Background technique [0002] The emergency shut-off valve is an indispensable safety component in the transportation of liquefied gas tankers. When an emergency occurs during loading and unloading of the tanker, the emergency shut-off valve can respond quickly to protect the equipment and ensure the safety of the staff and avoid safety accidents. Whether the emergency shut-off valve can work normally is related to the entire safety production process, so it is particularly important to test the performance of the emergency shut-off valve. The calibration of the emergency shut-off valve is mainly divided into sealing performance calibration, pressure resistance calibration, cut-off time calibration and over-current cut-off calibration. Most of the current emergency shut-off valve calibration devices adopt relati...
