Description
Technical field
The present invention relates to the valve of a kind of earthquake gas safe when taking place, particularly a kind of earthquake safety shutoff value.
Background technique
In 8 grades of violent earthquakes of Wenchuan, China Sichuan generation on May 12, cause Sichuan stricken area people's massive losses, cause the countries in the world government and the people's concern, seismic waves caused that large size house collapse, casualties, running water pipe shatter, electrical network suffers that serious destruction, gas pipeline are badly shaken, cause gas leakage when earthquake took place.China now is in seismic belt frequent active stage, and large, medium and small earthquake takes place in recent years to be had for several times, and causes that party and state leaders and governments at all levels pay much attention to.Particularly the gas transmission and distribution pipeline is in earthquake, as leaks, and consequence is hardly imaginable, not only causes big fire to blaze, and jeopardizes people's life safety.Behind the Wenchuan earthquake of Sichuan, we should draw a large amount of lessons, make people's the shockproof consciousness of preventing obtain reinforcement.In a large amount of data-searching, can not cut off gas source automatically within several seconds when also finding in earthquake in China, the safety of guaranteeing combustion gas with do not leak.Only find superpressure or decompression safety cut-off valve and Safety relief valve etc. in the market in China.5.5 the earthquake that level is above has just brought destructiveness to building, when destructive earthquake takes place, can close the Safety valve that cuts off gas source rapidly, the medium that prevents pipeline causes big harm to external leakage or air feed downstream.Developing earthquake safety valve, is the task of top priority, is the major issue of benefiting the nation and the people, and there is no risk of defense.
Summary of the invention
Purpose of the present invention overcomes above deficiency, provides a kind of and can cut off gas source effectively rapidly when earthquake, and can report to the police automatically, guarantees that combustion gas is not leaked and the earthquake safety shutoff value of safety.
The technical solution adopted for the present invention to solve the technical problems is: contain valve body, steel ball, outer casing, left side plate, last pin, downside pin, right panel, locking plate, connecting screw rod, Rotating boom, the valve port pad, valve port, lining, resetting shaft, torsion spring, the sealing plug screw, spanner resets, warning device, valve body links to each other with valve port, steel ball is arranged on the locating slot of left plate, contactor on the warning device contacts with steel ball point, by last pin left plate is connected with right panel, downside pin is established the lower end into left plate, by connecting screw rod locking plate and Rotating boom are connected together, the valve port pad is fixed on the connecting screw rod by a jump ring, lining is embedded in the valve body, bush hole is connected with the top of resetting shaft, Rotating boom is connected with the hexagonal position of resetting shaft, torsion spring one end is fixed on the valve body, the other end is stuck on the Rotating boom, the sealing plug screw screws in the valve body, the spanner that resets is connected with resetting shaft, and outer casing is arranged on shake and takes off on the device.
The present invention is by shut-off means, device is taken off in shake, three major components of warning device are formed, adopted lever principle, taken off the vibration frequency of device induction earthquake by shake, the steel ball that shake is taken off on the device is shifted, when the steel ball slippage to the shut-off means right panel, change has just taken place in balance pivot, impels the downside pin sheet to break off relations, and makes the shut-off means throttle down that is swift in motion, cut off ducted gas source, stop flowing of medium.When the earthquake that takes place more than 5.5 grades; the steel ball that seismic waves takes off shake left plate on the device separates automatically with the contactor of warning device; just can send emergency alarm sound in about 1 time in second; remind operator's shutdown or staff to escape or be dispersed into safe place, guarantor's life safety immediately.
Beneficial effect of the present invention is: when the earthquake more than 5.5 grades takes place; take off device throttle down rapidly by shut-off means, shake; cut off ducted gas source; stop flowing, not leaking of medium; guarantee the safety of gas pipeline, when earthquake took place, warning device just can sound the alarm in about 1 time in second; remind operator's shutdown or staff to escape or be dispersed into safe place, guarantor's life safety immediately.

Embodiment
In the drawings: valve body 1 links to each other with valve port 12; steel ball 2 is arranged on the locating slot of left plate 4; the contactor of warning device 18 contacts with 2 of steel balls; by last pin 5 left plate 4 is connected with right panel 7; downside pin 6 is established the lower end into left plate 4; by connecting screw rod 9 locking plate 8 and Rotating boom 10 are connected together; valve port pad 11 is fixed on the connecting screw rod 9 by a jump ring; lining 13 is embedded in the valve body 1; lining 13 holes are connected with the top of resetting shaft 14; Rotating boom 10 is connected with the hexagonal position of resetting shaft 14; torsion spring 15 1 ends are fixed on the valve body 1, and the other end is stuck on the Rotating boom 10, and sealing plug screw 16 screws in the valve body 1; the spanner 17 that resets is connected with resetting shaft 14; outer casing 3 is arranged on shake and takes off on the device, prevents that mainly dust from falling on the machine, plays a protective effect.Steel ball 2 is on the locating slot of left plate 4, and the width size of locating slot can be regulated the earthquake magnitude of steel ball 2 induction earthquakes, generally sets earthquake magnitude and reaches Richter scale more than 5.5 grades.Contactor on the warning device 18 contacts with 2 of steel balls, as when earthquake more than 5.5 grades takes place, the vibrations of seismic waves will separate the steel ball on the left plate 4 automatically with contactor on the warning device 18, after a separation, just greater alarm can take place about 1 time in second greatly, reminds people is escaped the place of safety.Left side plate 4, right panel 7 have adopted the lever construction composition with last pin 5.When earthquake, device starting is taken off in shake, is just rolled on the other end right panel 7 by the steel ball on left plate 4 locating slots, and under the gravity of steel ball 2, balance pivot impels shut-off means with valve closing with regard to change.Can not cause that in slight vibrations below 5 grades shake takes off the device starting.When earthquake takes place, earthquake magnitude reaches Richter scale more than 5.5, or building is destroyed, shock wave passes to earthquake safety shutoff value, steel ball 2 on plate 4 locating slots of a left side is rolled on the right panel 7, right panel 7 is under the steel ball action of gravity, right panel 7 is to moving clockwise, right panel 7 can drive left plate 4 and rotate to clockwise direction when clockwise direction rotates, impel downside pin 6 and locking plate 8 to break off relations locking plate 8, Rotating boom 10, valve port pad 11 is driven by torsion spring 15, rotates around resetting shaft 14 axle center, cover valve port 12 until valve port pad 11, cut off medium channel, the sealing one of valve port pad 11 is to produce thrust by torsion spring 145, the 2nd, by the pressure of medium itself valve port pad 11 is propped up tightly, valve is reached fully close, do not leak.
In embodiment illustrated in fig. 2:
Illustrate: to State Patent Office's application, warning device has a detailed description in conjunction with the accompanying drawings on the same day for automatic alarm device for earthquake safety shutoff valve and the present invention.
