Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-3, an air gap water inlet device for a drinking water pipeline system comprises a water supply tank 1, an air gap water inlet pipe 2, a pipe 201 with a bell mouth, a sealer 202, a guide rod 203, a sleeve 204, a connecting rod 205, a floating body 206, a pressure sensor 3, a stop valve 4, an air supplement port 5, a safety valve 6, a differential pressure liquid level sensor 7, a water outlet pipe 8, a drinking water pipe 9, a drinking water external pipe network 10 and a water inlet pipe 11. The external pipe network 10 of domestic drinking water is connected with the water inlet pipe 2 with air gap through the stop valve 3, wherein the water inlet pipe 2 with air gap is located at the gas phase space of the water supply tank 1, the pressure sensor 3, the air supply port 5 and the safety valve 6 are located at the upper end enclosure of the water supply tank 1, the pressure difference liquid level sensor 7 is located at the position, close to the bottom tank wall, of the water supply tank 1, the water outlet pipe 8 is located at the lower end enclosure of the water supply tank 1, and the water outlet pipe 8 is connected with the domestic drinking.
Take air gap inlet tube 2 including taking horn mouth takeover 201, the setting is taken guide bar 203 and the sleeve pipe 204 of setting at the guide bar tip of horn mouth takeover 201 bottom, guide bar 203 is along taking horn mouth takeover 201 bottom circumference to set up evenly three, and enclose and connect and form installation space, set up sealer 202 in the installation space, sealer 202 bottom is equipped with connecting rod 205, connecting rod 205 bottom is equipped with body 206, sealer 202 can pass through body 206, float from top to bottom in the installation space, and can take horn mouth takeover 201 through the shutoff of sealer 202.
According to the rationality of the equipment, the overall dimension of the water supply tank 1, the structural dimension of the water inlet pipe 2 with the air gap and the liquid level and the pressure value in the water supply tank are designed. When guaranteeing the user water consumption, can guarantee the requirement of water consumption, when the external pipe network of life drinking water breaks down, can prevent that water from flowing backwards to external pipe network.
The working process is as follows:
when the device normally started, the user passed through 8 water-consuming of outlet pipe, when pressure in the water supply tank 1 was less than the pressure of external life drinking water outside pipe network 10, the water in the external life drinking water outside pipe network 10 got into water supply tank 1 through taking air gap inlet tube 2, and the pressure of up to water supply tank 1 and external life drinking water outside pipe network 10 equals. When external life drinking water outside pipe network 10 breaks down unexpected the time of cutting off the water, go back to external life drinking water outside pipe network 10 in the water supply tank 1 gas reflux, tank internal pressure reduces, 8 well water reflux to water supply tank 1 in the outlet pipe, the liquid level risees in the jar, when the liquid level reaches high liquid level setting value, stop valve 4 on the pressure differential hydraulic pressure sensor 7 chain shut-down inlet tube 11, when the liquid level continues to rise, body 206 drives sealer 202 under liquid buoyancy effect and rises, sealer 202 forms sealedly with the horn mouth of taking horn mouth takeover 201 bottom, ensure to prevent under the stop valve 4 failure condition of inlet tube 11 that the water in the jar from flowing backwards to the outside pipe network of life drinking water. When the external pipe network returns to normal, the gas is supplemented into the water supply tank 1 through the gas supplementing port 5, so that the liquid level in the tank reaches the normal operation liquid level height. When the gas is supplemented into the water tank through the gas supplementing port 5, and the pressure in the water tank 1 reaches the tripping pressure of the safety valve 6, the safety valve 6 trips to play a role in protecting the water tank 1.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included within the protection scope of the present invention.
