Background

At present, the concrete mixing transport vehicle generally adopts a chassis gas cylinder to be connected with a water tank of the vehicle through a gas valve component, the air pressure in the water tank is controlled by a gas valve component three-way valve, so that the water tank is filled with water or the vehicle is flushed, the demand of the concrete transportation is more and more along with the implementation of national infrastructure, the performance requirement of customers on the mixing vehicle is higher and higher, many mixing vehicles use a water filling port assembly to fill the water tank in the charging process, if the mixing vehicle is not filled with water after being filled with the water, the charging of subsequent vehicles is influenced, and because the water is not clean enough in some mixing stations, impurities cover a water tank liquid level meter after the mixing vehicles are used for a period of time, so that many customers cannot directly observe whether the water tank is filled with the water or not, if the water filling port assembly cannot be closed in time after the water tank is filled with the water, the excessive water can, causing water accumulation in the chassis air reservoir and finally damaging the chassis.

Disclosure of Invention

The invention aims to provide a quick water adding anti-overflow and anti-leakage device which has higher water adding speed and can prevent redundant water from entering a chassis air storage cylinder after a water tank is filled with water, so that accumulated water in the chassis air storage cylinder finally damages a chassis.

In order to solve the problems, the invention adopts the technical scheme that: the device comprises a water filling port assembly, an overflow pipe assembly, a water tank, an air valve assembly and a chassis air storage cylinder; the water filling port assembly is connected with a water inlet of the water tank through a water outlet pipe, the air valve component comprises a first three-way valve, an operating handle, a pressure gauge and a pressure limiting valve, a first interface of the first three-way valve is connected with a first air outlet formed in the top of the water tank through a first air pipe, a second interface of the first three-way valve is connected with the chassis air cylinder through a second air pipe, a third interface of the first three-way valve is connected with the pressure gauge through a third air pipe, the pressure limiting valve is arranged on the second air pipe, and the change of the position of a valve core in the first three-way valve is controlled by the operating handle; and a second air outlet is arranged below the first air outlet of the water tank, the second air outlet is connected with the overflow pipe assembly, and a first valve is arranged on the overflow pipe assembly.

In the above technical solution, a more specific technical solution may also be: the water filling port assembly comprises a second three-way valve, a fourth interface of the second three-way valve is connected with an outlet of the water inlet pipe, a fifth interface of the second three-way valve is connected with an inlet of the water outlet pipe, and a second valve is arranged on the water inlet pipe.

Further, the first valve is a ball valve.

Further, the second valve is a ball valve.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:

when water is added, the first three-way valve of the air valve component is opened to a water adding position by the operating handle, the first valve and the second valve are opened, water enters the water tank from the water outlet pipe of the water adding port assembly, one part of air in the water tank is discharged from the first three-way valve of the air valve component through the first air pipe, the other part of air is directly discharged from the overflow pipe assembly, and due to the fact that the exhaust channel is additionally arranged, the air discharging speed is accelerated, the faster the air in the water tank is discharged, the smaller the pressure is, the faster the water adding speed is, and the water adding efficiency of the water tank is improved; because the second air outlet of the water tank is arranged below the first air outlet, after the water tank is filled with water, redundant water can flow out of the overflow pipe assembly to remind that the water tank is filled with water, the water filling port assembly needs to be closed to stop adding water, and the condition that water enters the chassis air storage cylinder from the first three-way valve of the air valve assembly is avoided.
