Distribution valve, material pumping system, concrete pump and fire pump truck

Abstract

The invention provides a distribution valve, a material pumping system, a concrete pump and a fire pump truck. The distribution valve is used for pumping materials and comprises a wear-resisting plate, a material outlet pipe and at least two material inlet pipes, wherein the wear-resisting plate is provided with a plurality of holes; one end of each material inlet pipe is cooperated with one hole of the wear-resisting plate; the other end of each material inlet pipe is communicated with one end of the material outlet pipe; and the material outlet pipe and the material inlet pipes are swung under the driving of a driving mechanism. The invention also provides the material pumping system, the concrete pump and the fire pump truck. According to the technical scheme provided by the invention, the displacement of the pumping system is greatly improved by the distribution valve comprising the multiple material inlet pipes and one material outlet pipe, and the material pumping efficiency is improved. Meanwhile, an independent stirring system is omitted, the production cost is lowered, and good economic benefit is brought for production enterprises.

Description

technical field [0001] The invention relates to concrete equipment, more specifically, to a distribution valve, a material pumping system containing the distribution valve, a concrete pump truck and a fire pump truck containing the pumping system. Background technique [0002] Among the commonly used concrete pumping distribution valves, there is an S-shaped pipe valve 1', which swings back and forth and docks between two material delivery cylinders under the driving force of the oil cylinder to complete the cyclic action of suction and push. unit. [0003] This S-shaped pipe valve has the following disadvantages: [0004] Since the S-shaped pipe valve is a single pipe, the output of the pumping system using this distribution valve is limited. In occasions where the demand for concrete is large, multiple pump trucks of this type are often required to work at the same time, which not only takes up a lot of construction work Space, requires multiple people to operate at the ...

Problems solved by technology

[0004] Since the S-shaped pipe valve is a single pipe, the output of the pumping system using this distribution valve is limited. In occasions where the demand for concrete is large, multiple pump trucks of this type are often required to work at the same time, which not only takes up a lot of construction work Space, requires multiple people to operate at the same time, high labor costs, high energy consumption, resulting in high construction costs, which is not conducive to improving the production efficiency of enterprises;

[0005] In addition, the mixing function of the S-shaped pipe valve is weak, and an independent mixing system needs to be installed in the pumping system, which increases the overall cost of the pump truck and reduces the effective space of the hopper
