Description

A high-pressure waterway control system for washing and sweeping vehicles

technical field

The utility model relates to a novel high-pressure waterway control system, in particular to a high-pressure waterway system of a cleaning vehicle for urban sanitation.

Background technique

At present, the high-pressure waterway control system of domestic cleaning and sweeping vehicles consists of water tanks, water level gauges, ball valves, filters, high-pressure water pumps, pressure regulating valves, overflow valves, solenoid valves, control cylinders/cylinders, nozzles, nozzles, etc.

When the system is working, the electrical system gives a signal to control the oil cylinder or cylinder to operate the ball valve switch. The structure is complex, it takes up a lot of space, and it is inconvenient to install.

Contents of the invention

With respect to the above-mentioned technical problems, the utility model provides a self-developed control system designed, which has a simple structure, small space occupation, low cost and convenient installation.

The technical scheme of the utility model is achieved in that:

A high-pressure waterway control system for washing and sweeping vehicles, including a water tank, a high-pressure water pump, a pressure regulating valve, a safety valve, an electromagnetic water valve, a nozzle, and a spray pipe; the water tank is connected to the water inlet of the high-pressure water pump, and the water outlet of the high-pressure water pump passes through A plurality of electromagnetic water valves are delivered to the spray gun and spray boom; the pressure regulating valve is connected between the water outlet of the high-pressure water pump and the electromagnetic water valve, the safety valve is connected in parallel with the electromagnetic water valve, and the water outlet of the safety valve is connected with the water tank; The water outlet of one of the electromagnetic water valves is connected to the water tank. When the high-pressure water circuit is not working, one of the electromagnetic water valves connected to the water tank is in an open state to ensure that the system is in an unloaded state. When any water valve is opened, the electromagnetic water valve connected to the water tank is in a closed state to ensure the normal operation of the system pressure.

Further, a ball valve and a filter are provided between the water tank and the high-pressure water pump.

Further, a pressure gauge is provided on the water delivery pipeline.

Compared with the prior art, the utility model has the following advantages:

1. The structure of the new high-pressure waterway system is more compact, and the electromagnetic water valve replaces the ordinary ball valve, which saves the oil cylinder or cylinder, and takes up less space.

2. Compared with the original high-pressure waterway system, the new high-pressure waterway system is easier to install and maintain.

3. In the original high-pressure water system, the electrical system controls the water ball valve through the oil solenoid valve or the air solenoid valve, while in the new high-pressure water system, the electrical system directly controls the electromagnetic water valve, eliminating the need for intermediate links, and the operation is more direct and reliable .

4. Compared with the original high-pressure waterway system, the cost of the new high-pressure waterway system is reduced.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1, the new model is mainly composed of a water tank 1, a water level gauge 2, a ball valve 3, a filter 4, a high-pressure water pump 5, a pressure gauge 6, a pressure regulating valve 7, a safety valve 8, an electromagnetic water valve 9, a nozzle 10, and a spray nozzle. Tube 11 is composed.

The above components form a new type of high-pressure waterway control system for washing and sweeping vehicles.

As shown in Figure 1, a liquid level gauge 2 is installed in the water tank 1 to facilitate water level monitoring; a high-pressure water pump 5 is connected to the water tank 1 through a pipeline, and a waterway master switch, namely a ball valve 3, is arranged in the middle; The water in the tank is filtered.

As shown in Figure 1, the outlet of the high-pressure water pump 5 is provided with a pressure gauge 6, a pressure regulating valve 7, and a safety valve 8, wherein the pressure regulating valve 7 and the safety valve 8 are connected in parallel to adjust the pressure of the waterway to the working pressure.

When the high-pressure water pump 5 was working normally, the water went through the high-pressure water pump 5 to the electromagnetic water valve 9 through the pressure regulating valve. The electromagnetic water valve 9 was directly controlled by the electrical system, and the water entered the nozzle 10 through the nozzle pipe 11 to spray.

As shown in Figure 1, when the high-pressure waterway is not working, the electromagnetic water valve 9 connected to the water tank 1 is in an open state to ensure that the system is in an unloaded state. When any ball valve in the other electromagnetic water valves is opened, the electromagnetic water valve connected to the water tank The water valve 9 is in a closed state to ensure the normal operation of the system pressure.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of changes or modifications within the technical scope disclosed in the present invention. Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
