Example 1:

referring to fig. 1-3, a fluid material distribution valve comprises a valve body 1, a bearing plate 2 and a rotating shaft 3, wherein the bearing plate 2 is arranged at an inlet end 1.2 of the valve body 1, a feeding port 2.1 communicated with the interior of the valve body 1 is arranged on the bearing plate 2, the rotating shaft 3 is arranged on a compression surface 2.2 of the bearing plate 2, the rotating shaft 3 and an outlet end 1.1 of the valve body 1 are coaxially arranged, and the compression surface 2.2 is used for being tightly attached to an outlet end of a material conveying cylinder on a hopper under the pressure action of the interior of the valve body 1.

Preferably, one surface of the pressure bearing plate 2 facing the valve body 1 is a pressure bearing surface 2.3, and the pressure bearing area of the pressure bearing surface 2.3 is more than one time of the cross-sectional area of the rotating shaft 3 (the pressure bearing area refers to a part bearing the pressure of the fluid material in the valve body 1 and does not include a feeding port); preferably 1 to 50 times, more preferably 1 to 5 times, and still more preferably 1 to 3 times. In this embodiment, the pressing surface 2.2 is made of a wear-resistant material, preferably cemented carbide.

Preferably, the extension line of 3 axes of rotation axis is located the inside of valve body 1, so set up can be with the area design of bearing plate 2 bigger for compress tightly face 2.2 and bearing face 2.3 maximize, guarantee to compress tightly the laminating area of face 2.2 and material transport cylinder exit end. After fluid materials are pumped into the valve body 1, the pressure of the fluid materials can simultaneously act on the pressure-bearing surface 2.3 of the pressure-bearing plate 2, so that a pressure can be applied between the pressure-bearing surface 2.2 and the outlet end of the material conveying cylinder, the pressure-bearing surface 2.2 is tightly attached to the outlet end of the material conveying cylinder, and the sealing between the pressure-bearing surface and the outlet end of the material conveying cylinder is realized; meanwhile, as the pressure of the fluid material acts on the pressure bearing surface 2.3, the gap generated by abrasion between the pressing surface 2.2 and the outlet end of the material conveying cylinder can be automatically compensated, and the condition of fluid material leakage is prevented.

Referring to fig. 1 and 3, the flow cross section inside the valve body 1 gradually decreases from the inlet end 1.2 to the outlet end 1.1, and the valve body 1 may be shaped like a trumpet.

Further, the flow cross section of the valve body 1 at the outlet end 1.1 is constant. Specifically, from the inlet end 1.2 to the outlet end 1.1, the distance from the inner wall of one side of the valve body 1 to the axis of the rotating shaft 3 is constant, and the distances from the inner walls of the other sides to the axis of the rotating shaft 3 are gradually reduced and then are constant.

The inside of the valve body 1 is in a form that the flow cross section is reduced from the inlet end 1.2 to the outlet end 1.1 and then is unchanged, compared with the existing S-shaped pipe valve, the flow resistance inside the valve body 1 in the embodiment is smaller, the flow is smoother, the pressure loss of fluid materials inside the valve body 1 is greatly reduced, and the fluid materials can be concrete or liquid (such as oil, water and the like).

Referring to fig. 2, the feeding port 2.1 is an arc-shaped waist hole which is simultaneously communicated with the outlet ends of more than two material conveying cylinders.
