Gas seismic circuit breaker

The invention relates to a gas seismic breaker, in particular to a gas seismic breaker which is simple in structure and can block gas input during an earthquake.

According to the reason, the earthquake occurred mainly because the plates were mutually squeezed. When the cumulative deformation energy exceeded the rock tolerance, the accumulated energy was released instantaneously and an earthquake occurred. Taiwan is located in the Pacific Rim seismic zone. Under the collision of the Eurasia plate and the Philippine Sea plate, earthquakes frequently occur. The earthquake will cause damage to houses, roads and other structures, and cause fires and other accidents, resulting in serious loss of life and property. It is difficult to accurately predict earthquakes. When people are in an earthquake, it is difficult to shut down gas and electricity one by one. However, in the event of an earthquake, gas (natural gas) is often leaked, and gas leaks and gas explosions The resulting fire, the loss of life and property is usually much greater than the direct damage caused by the earthquake. Therefore, how to automatically shut down gas when an earthquake occurs, to avoid the expansion of the disaster, is the need for academic and industrial issues to solve the problem.

See U.S. Patent No. 4,331,171, "Seismic Gas Shutoff Valve", No. 4,485,832, "Automatic Gas Shutoff Valve", No. 4,165,758, "Seismic Response Valve" and "No. 5787917" Earthquake gas automatic shutdown system". . Etc., which is a prior art patent that can cut off gas supply such as gas in the case of an earthquake, the "seismic gas shut-off valve" of No. 4,331,171, "Automatic gas shut-off valve" No. 4,485,832, No. 4165758 "Seismic Response Valve" and "Seismic Gas Automatic Shutdown System" No. 5787917. . Although the patent pre-existing case has sensed the effect of automatically cutting off gas supply such as gas after the earthquake; however, in actual use, the "seismic gas shut-off valve" of US Patent No. 4331171 and "No. 4485832" Automatic gas shut-off valve, when installed and used, the valve body must be installed in an absolute horizontal position. If the direction is slightly inclined, it will affect the sensitivity of the valve. If the valve is not in a good level, the valve The inner sphere is easily separated from the original position when subjected to a slight impact or vibration, and the valve body is actuated to cut off the gas supply, or at the time of the earthquake and after the aftershock, the valve body is blocked by the valve body to supply the gas supply passage. Being shocked out, causing gas to resume supply, causing gas leakage and gas explosion hazards during the earthquake. The "seismic response valve" No. 4165758 and the "Seismic gas automatic shutdown system" No. 5787917 The structural design is so complicated that the manufacturing cost thereof is relatively increased, and since it is composed of a plurality of components, it is not only time-consuming and labor-intensive to assemble, but also increases the mutual damage rate between the components, and is easy.
