Abstract
The utility model involves an auto-close valve when earthquake happens. The upside of a lower valve body is mounted with a middle valve body and a steel ball is mounted in the chamber formed by the lower valve body and the middle valve body, the upside of the steel ball is arranged with a positioning groove concentrically connected with a valve link, the lower side of the valve link props up with the upside of the steel ball, the central part of the lower valve body is mounted with a serrated raising shaft and the serrated raising shaft engages with the pinion, the upside of the raising shaft is connected with the steel ball and the lower side of the raising shaft is arranged with a blind hole, the blind hole is mounted with a back-moving spring. The utility model is characterized by the simple construction, reasonable design, low cost, and the utility model overcomes the disadvantage that the electromagnetic valve needs power supply. In addition, the valve is automatically closed when the strong earthquake happens thereby prevents the gas pipelines from breach, leakage and other secondary disasters.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of oil transportation, gas pipeline safety 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.The U.S. has fully-machinery type coal gas seismic valve, and at earthquake-prone region this valve has been installed, but costs an arm and a leg, and can't popularize at China's earthquake-prone region.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, cheap automatic earthquake gas shutoff door.
In order to achieve the above object, the technical solution adopted in the utility model is: by in the chamber that constitutes between the valve body during be equipped with at position, valve body upper end down steel ball being housed, steel ball top is provided with and the valve rod concentric setting sleeve that joins, the valve rod lower end relies on position, steel ball upper end, following valve body center portion is equipped with the dentation apical axis and is meshed with the tooth axle, the apical axis upper end joins with steel ball, and its lower end part has blind hole, and Returnning spring is housed in the blind hole.
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 prevent that oil and gas pipeline from breaking at automatic-closing valve under the earthquake situations condition doughtily, causes to leak and the generation of secondary disaster.

Fig. 2 is the utility model valve closing view.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model is by in the chamber 14 that constitutes between the valve body 4 during be equipped with at position, valve body 6 upper end down steel ball 5 being housed, steel ball 5 tops are provided with and the valve rod 1 concentric setting sleeve 11 that joins, valve rod 1 lower end relies on position, steel ball 5 upper end, following valve body 6 center portions are equipped with dentation apical axis 8 and are meshed with tooth axle 7, apical axis 8 upper ends and steel ball 5 join, and its lower end part has blind hole 13, and Returnning spring 9 is housed in the blind hole 13.
Following valve body 6 two ends are respectively equipped with mounting hole 10.
Task of the present utility model realizes as follows, forms valve body by bonnet, middle valve body, following valve body and mounting hole.Form the self acting stop valve door device by import, outlet, valve rod, setting sleeve, steel ball, tooth axle, apical axis, Returnning spring.During no earthquake, with valve rod jack-up, coal gas can flow to outlet from air intake along the direction of arrow to valve rod by Returnning spring, apical axis and steel ball.When earthquake, steel ball is separated from apical axis under the effect of seismic force F, and valve rod is because valve closing is fallen in action of gravity.
When needs are connected coal gas, turn the tooth axle with screw-driver, stir apical axis and move down, steel ball is seated on the apical axis, the backwash of leaning on Returnning spring and tooth axle is with ball and valve rod jack-up then, and valve opens, the coal gas circulation.
With reference to Fig. 1 valve opening state schematic cross-section.Form valve body by bonnet 2, middle valve body 4, following valve body 6 and mounting hole 10.Form by inlet 3, outlet 12, valve rod 1, setting sleeve 11, steel ball 5, tooth axle 7, apical axis 8, Returnning spring 9.During no earthquake, Returnning spring 9, apical axis 8 and steel ball are with valve rod 1 jack-up, and coal gas can flow to outlet 12 from air intake 3 along the direction of arrow.With reference to Fig. 1 valve opening state schematic cross-section and Fig. 2 valve closing state schematic cross-section.When earthquake, steel ball 5 is separated from apical axis 8 under the effect of seismic force F, and valve rod 1 is because valve closing is fallen in action of gravity.
With reference to Fig. 2 valve closing state schematic cross-section.When needs are connected coal gas, turn tooth axle 7 with screw-driver, stir apical axis 8 and move down, steel ball 5 is seated on the apical axis 8, the backwash of leaning on Returnning spring 9 and tooth axle 7 is with steel ball 5 and valve rod 1 jack-up then, and valve opens, the coal gas circulation.
The utility model is when no earthquake, and with valve rod jack-up, coal gas can flow to outlet from air intake along the direction of arrow to valve rod by Returnning spring, apical axis and steel ball.When earthquake, steel ball is separated from apical axis under the effect of seismic force F, and valve rod is because valve closing is fallen in action of gravity.
