Abstract
The utility model discloses a water inlet and air exhaust device of a sprinkler, which comprises a water storage tank. The water storage tank is arranged on a chassis truck of the sprinkler, bent heads at the upper ends of Z-shaped water pipes are tightly and fixedly communicated with the lateral face of the top of the rear end of the water storage tank, vertical parts in the middle of the Z-shaped water pipes tightly prop against the outer side of the rear end of the water storage tank, bent heads at the lower ends of the Z-shaped water pipes are positioned at the outer side of the bottom of the rear end of the water storage tank and are connected with fire hydrants by means of external threads, and the two sets of Z-shaped water pipes respectively and symmetrically prop against two edges of the outer side of the rear end of the water storage tank. The water inlet and air exhaust device has the advantages that the Z-shaped water pipe at one side is used for water feeding, the Z-shaped water pipe at the other side is used for air exhaust; when the Z-shaped water pipe at one side is used for water feeding and the water storage tank is filled with water, the water overflows out of the Z-shaped water pipe at the other side to immediately cut off pressurized tap water; and during sprinkling of the sprinkler, the air can be sucked through the Z-shaped water pipes at the two sides, so that the water storage tank can be prevented from generating negative pressure.
Description
Technical field
The utility model relates to a kind of sprinkling truck that is used for gardening or road, water inlet of particularly a kind of sprinkling truck and exhaust plant.
Background technology
Traditional sprinkling truck is the water inlet pipe that the band valve is equipped with in centre or the both sides of bottom behind water tank, and wherein the pressure tap water of annotating is convenient to be connected with fire hydrant in the water inlet pipe elder generation of both sides and be unified into the water inlet pipe of a band valve.Be provided with steam vent at the water tank top,, discharge the air in the water tank so that during filling pressure tap water.
The utility model content
The purpose of the utility model is to provide water inlet of a kind of sprinkling truck and exhaust plant, and this apparatus structure is simple, with low cost, can realize water inlet and two functions of exhaust simultaneously.
The technical scheme of the utility model is: water inlet of a kind of sprinkling truck and exhaust plant comprise the water tank that is installed on the sprinkling truck chassis; The upper end elbow of zigzag water pipe and water tank rear end fastening connection of top-side, the vertical part in zigzag water pipe middle part is near the outside, water tank rear end; The lower end elbow of zigzag water pipe is positioned at water tank rear end bottom outside, relies on external screw thread to be connected with fire hydrant.Said zigzag water pipe is two covers, and symmetry is near the both sides in the outside, water tank rear end respectively.
The beneficial effect of the utility model is:
During 1, through side zigzag water pipe filling pressure tap water, opposite side zigzag water pipe can exhaust;
2, through side zigzag water pipe filling pressure tap water, when water tank is filled water, water will overflow from opposite side zigzag water pipe, cut off filling pressure tap water immediately;
3, during the sprinkling truck spray water, can pass through both sides zigzag water pipe air inlet, prevent to produce in the water tank negative pressure.
