When combustible gas in the pipeline burns, the water seal well does not have the function of blocking burning, and burnt gas can be directly emitted out of the well, so that the water seal well is unsafe.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an integral type water seal inspection shaft, the vertical setting of T shape end of this inspection shaft inlet tube, outlet pipe, the last port stopper of T shape end has the end cap, can block gas combustion route and prevent that combustible gas from transmitting the outlet pipe through the inlet tube and continuously burning, through the burning of water shutoff in the well, can follow the pit shaft and discharge after the gas combustion is obstructed.
The technical scheme of the utility model is that: the utility model provides an integral type water seal inspection shaft, it is including the inlet tube that is T shape, outlet pipe, base, well room and the pit shaft that is T shape, its characterized in that, well room and pit shaft are vertical setting and pit shaft and connect in the well room upper end, well room and pit shaft are twice winding fashioned structure pipe, and open the well room side has left connecting hole and right connecting hole, inlet tube fixed connection on the left connecting hole of well room, outlet pipe fixed connection on the right connecting hole of well room, the T shape end of inlet tube and outlet pipe all stretches into in the well room, the vertical setting in T shape end, the last port stopper of T shape end has the end cap, the lower port of T shape end extends 25cm at least down, base sealing connection is port under the well room.
This inspection well sets up there is combustible gas in the factory, on the sewage pipe network of flammable liquid vapour or greasy dirt, water in the well chamber can circulate, water gets into from T shape end, if the liquid level is higher than the time of outlet pipe, water can follow the outlet pipe and flow out until being less than the outlet pipe, combustible gas is when the inlet tube burning, the upper port that can not follow T shape end is blockked by the end cap and flows out and get into the outlet pipe, combustible gas's burning route has been blocked, utilize the water seal to block burning and explosion, gaseous can be followed the pit shaft and discharged after being fire-retardant, this inspection well can prevent whole pipeline burning.
Furthermore, the water outlet pipe is positioned right below the shaft, and the diameter of the water outlet pipe is 75-200 cm.
Furthermore, the diameter of the water inlet pipe is 75-200 cm.
Further, the diameter of the well bore is smaller than that of the well chamber.
Furthermore, the plug is a heat-soaking asphalt wood plug. The wood plug treated by the heat-soaked asphalt has corrosion resistance and water resistance.
Furthermore, a closing-up reinforcing rib is arranged on the outer side of the joint of the shaft and the well chamber. The close-up reinforcing rib enhances the strength of the joint of the shaft and the well chamber and prevents the damage and the leakage.
This integral type water seal inspection shaft structure's advantage has:
1. this inspection shaft inlet tube, the vertical setting of T shape end of outlet pipe, the last port stopper of T shape end have the end cap, can block gas combustion route and prevent that combustible gas from transmitting the outlet pipe through the inlet tube and continuously burning, through the burning of water shutoff in the well, can follow the pit shaft and discharge after the gas combustion shutoff.
2. The close-up reinforcing rib enhances the strength of the joint of the shaft and the well chamber and prevents the damage and the leakage.
3. The well chamber of this inspection shaft, pit shaft all are twice winding pipe, and intensity is high itself, and this inspection shaft all makes in advance to accomplish and transports again to the place that needs the installation and install, and the transportation is convenient, and construction convenience is swift.
