Abstract
The utility model relates to a full-mechanical large-caliber automatic fuel gas closing valve in case of an earthquake, which comprises a supporting leg. An upper valve body with a cavity is fixedly installed on a portion of the upper end of the supporting leg, an air inlet and an air outlet are installed on the left side and right side of the upper valve body respectively, a lower valve body with a spherical cavity is installed below the upper valve body, a rack top shaft meshed with a reset switch is arranged on the portion at the center of the bottom of the lower valve body, a chromium-plated steel ball is arranged at the upper end of the rack top shaft, and an end cover is installed on the portion of the lower end of the rack top shaft. A concentric locating copper sleeve connected with a valve rod is arranged on the portion at the center of the inside of the cavity of the upper valve body above the chromium-plated steel ball, and the lower end of the valve rod abuts against the portion of the upper end of the chromium-plated steel ball. The full-mechanical large-caliber automatic fuel gas closing valve in case of the earthquake is simple in structure, reasonable in design and low in cost, and overcomes the shortcoming that an electromagnetic valve needs a power source. The large valve of a fuel gas pipeline supply station can be automatically closed under the condition of strong earthquakes, and secondary disasters and leakage caused by damage of a fuel gas pipeline are avoided.
Description
Technical field
The utility model relates to a kind of large bore valves, especially relates to a kind of gas pipeline automatic safe control valve when shaking doughtily.
Background technique
At present, use solenoid valve for the safety control of oil transportation, gas pipeline, the control of this solenoid valve needs Ac or direct current more, and power consumption is bigger, and when shaking doughtily, general electrical network paralysis can't be controlled.China has developed small-bore earthquake combustion gas automatic-closing valve, but can not be used for the seismic safety control of the gas pipeline of gas station supplier.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, with low cost, the automatic earthquake combustion gas of the complete mechanical heavy caliber throttle down of ability automatic safe control valve when macroseism.
In order to achieve the above object; The technological scheme that the utility model adopts is: comprise leg, be fixed with the upper valve body of cavity at position, leg upper end, the upper valve body left and right sides is separately installed with suction port, air outlet; The upper valve body below is equipped with the following valve body of dribbling shape chamber; Following valve body is gone to the bottom, and central position is provided with the tooth bar apical axis and reset switch meshes, and is positioned at tooth bar apical axis upper end and lays the chromium plating steel ball, and lower end part is equipped with end cap; Chromium plating steel ball top is provided with the concentric locating copper sheathing that joins with valve rod with the interior central position of upper valve body chamber, and the valve rod lower end relies on position, chromium plating steel ball upper end portion.
The utility model has the advantages that:
Simple in structure, reasonable in design, with low cost; The utility model has overcome the shortcoming that electromagnetic valve needs power supply; Can be at the large-scale valve at automatic self-closing gas pipeline supply station under the earthquake situations condition doughtily, prevent that gas pipeline from destroying to cause to leak and the generation of secondary disaster.
