Distribution valve and mud or concrete pump with same

Abstract

The invention discloses a distribution valve and a mud or concrete pump with the same. The distribution valve comprises a valve block, a valve oil cylinder and a column compartment, the valve block is internally and transversely provided with a square section channel; two surfaces perpendicular to the square-shaped section channel are both provided with two circular holes communicated with the square-shaped section channel; circular tubes with flanges extends outwards from the circular holes; the circular tubes are internally provided with sleeves; the square-shaped section channel of the valve block is communicated with the column compartment of a uniform section; the column compartment is internally provided with a rectangular-column plunger; the outer end of the rectangular-column plunger is provided with a plunger rod; and the valve oil cylinder is arranged outside the valve block. A main oil cylinder of the mud or concrete pump is connected with a mud cylinder through a wash trough; a sensor is arranged above the wash trough; and the mud cylinder is communicated with the two circular tubes of the distribution valve through a V-shape tube. The invention adequately reflects theadvantages of multi-functions of the distribution valve and the mud or concrete pump. The mud or concrete pump is not only a self-suction type mud pump, but also a medium-pressure concrete pump; and in addition, the distribution valve can be used for a transmission part and can be used as a compensating cylinder.

Description

technical field [0001] The invention relates to a fluid conveying machine, in particular to a distributing valve and a mud or concrete pump with the distributing valve. Background technique [0002] For the water conservancy department on the agricultural front, the era of vigorous farmland capital construction in the 1960s has passed. Due to years of disrepair, farmland water conservancy drainage and irrigation facilities are in urgent need of dredging. At present, there is only one kind of mud pump, and the maximum mud content for removing silt is only 25 %, it will cause floods and disasters when used, and it is difficult to meet the requirements now. [0003] After the implementation of the annual production responsibility system in the countryside in 1978, farmers dug fish ponds in low-lying land, which has been silted up for many years and is in urgent need of dredging. The current method: wait until winter to ditch the fish ponds to improve water use, and then dig th...

AI Technical Summary

Problems solved by technology

[0007] 1. The manufacturing process of the valve body is complicated, and the resistance, wear, vibration, and crushing force are greater when used, and the power consumption is greater;

[0008] 2. The function is single, one pump cannot be used for multiple purposes or one valve can be used for multiple purposes, and there is dependence on feeding;

[0009] 3. The feeding method is an open hopper, feeding and feeding by external power, which consumes energy;

[0010] 4. The core of the disadvantages of the two valves is that they are not sealed, they cannot be self-priming, and they are easy to enter air. They are easy to fire during the process of conveying materials, and it is easy to cause the volume of the clay cylinder to be unsaturated;

[0011] 5. Especially when transporting downhill, it is more difficult, sand and gravel separation, mud and water separation, easy to segregate, easy to block the pipe, affect the progress, and the volume is large and expensive
