Description

System for be used for demarcating micropressure steady voltage valve

Technical Field

The utility model relates to the technical field of oil gas storage and transportation, in particular to a system for calibrating a micro-pressure stabilizing valve.

Background

The existing micro-pressure stabilizing valve is a device for guaranteeing the stability of the internal pressure value of the oil storage tank floating disc when in use, and the main structure of the micro-pressure stabilizing valve comprises a valve cover and a valve cavity, and the working principle of the micro-pressure stabilizing valve is realized by the dead weight of the valve cover above the valve cavity: when the pressure of the gas in the valve cavity multiplied by the area of the valve cover is larger than the dead weight of the valve cover, the valve cover is opened, and the gas is discharged outwards; when the upward thrust borne by the valve cover is smaller than or equal to the dead weight of the valve cover, the valve cover falls back to the upper part of the valve cavity to cover the outlet of the valve cavity, and after the upward thrust in the valve cavity is balanced in this way, the dead weight of the valve cover is used as the sealing force of the micro-pressure stabilizing valve to prevent the gas in the valve cavity from leaking and keep the pressure in the valve cavity. The micro-pressure stabilizing valve is mainly characterized in that the valve body dead weight is used for restraining the internal pressure of the valve body, the valve body dead weight is a fixed value, the micro-pressure stabilizing valve cannot meet the use under various working conditions, and the sealing effect of a valve cover and a valve cavity is poor, so that the sealing problem of the micro-pressure stabilizing valve cannot be guaranteed.

In order to solve the technical problems, the Chinese patent with the prior art publication number of CN219734378U discloses a liquid seal type micro-pressure stabilizing valve which is applied to an oil storage tank floating disc, and the valve core floating drum is reversely buckled on the air guide pipe through the arrangement of a pressure stabilizing seat, a shell, an air guide pipe, a liquid sealing layer and a valve core floating drum in cooperation with the liquid sealing layer, and the bottom of the valve core floating drum is positioned in the liquid sealing layer, so that the liquid seal of the valve core floating drum is realized, and the internal air pressure of the valve core floating drum is isolated from the external air pressure of the valve core floating drum, so that the tightness of the interior of a valve body is ensured. When the air pressure in the micro-pressure stabilizing valve is increased to a larger pressure, the whole valve core pontoon can move to be above the liquid level of the liquid sealing layer, and air is discharged from the valve core pontoon to the outside of the shell, and meanwhile, the valve core pontoon stops exhausting after the pressure in the valve core pontoon is reduced to be below the liquid level, so that the stability of the pressure value in the micro-pressure stabilizing valve is ensured.

However, in the liquid-sealed micro-pressure stabilizing valve with the publication number of CN219734378U, whether the exhaust pressure after the opening of the stabilizing valve is completely matched with the set exhaust pressure cannot be guaranteed, so that in the using process, the technical problem that the actual exhaust pressure of the stabilizing valve is inconsistent with the preset exhaust pressure exists, normal use of the micro-pressure stabilizing valve cannot be guaranteed, and potential safety hazards can be caused to the whole oil-gas storage and transportation system.

Therefore, it is desirable to provide a system for calibrating a micro-pressure regulator valve to calibrate whether the pressure of the actual opening exhaust gas of the micro-pressure regulator valve coincides with the preset opening exhaust gas pressure, so as to ensure the quality of the product.

Therefore, the actual performance of the micro-pressure stabilizing valve 500 can be effectively checked, thereby guaranteeing the stability of the product quality.

Referring to fig. 5 and 6, the micro-pressure stabilizing valve 500 in the present embodiment is a micro-pressure stabilizing valve 500 disclosed in the chinese patent of utility model with publication number CN219734378U, and the structure and working principle of the micro-pressure stabilizing valve 500 can be specifically referred to paragraphs 0043-0048 in the specification.

The specific micro-pressure stabilizing valve 500 comprises a pressure stabilizing seat 01, a shell 02, an air duct 03, a liquid sealing layer 04 and a valve core float bowl 05, wherein the pressure stabilizing seat 01 comprises a pressure stabilizing cavity 0101, a cover plate 0102 and an air inlet pipe 0103, the cover plate 0102 is fixed at the upper end of the pressure stabilizing cavity 0101, and the air inlet pipe 0103 is positioned at one side of the pressure stabilizing cavity 0101 and communicated with the pressure stabilizing cavity 0101; the other side of the pressure stabilizing seat 01 is also provided with a measuring pressure measuring part 0104 for detecting the pressure intensity inside the pressure stabilizing seat 01, the pressure measuring part 0104 is a pressure gauge or a U-shaped tube pressure gauge 610, so that the pressure value inside the pressure stabilizing seat can be monitored in real time, the shell 02 is fixed on the pressure stabilizing seat 01, one end of the air duct 03 is communicated with the pressure stabilizing seat 01, the other end of the air duct 03 extends upwards into the shell 02, a placing cavity 06 is formed between the peripheral wall of the air duct 03 and the inner peripheral wall of the shell 02, the liquid sealing layer 04 is positioned in the placing cavity 06, the bottom end of the valve core pontoon 05 is arranged inside the liquid sealing layer 04, the liquid sealing of the valve core pontoon 05 is realized, the bottom of the valve core pontoon 05 is communicated with the air duct 03, and the top end of the valve core pontoon 05 extends upwards into the shell 02'; see the Chinese patent application with publication number CN219734378U for details.
