摘要： Disclosed is a valve for use in particulate material processing. The valve has a rotatable closure member having a convex sealing surface and a resilient sealing ring moveable between a first configuration in which the sealing ring forms a seal around a circumference of the convex sealing surface; and a second position in which a circumferential gap is defined between the convex sealing surface and the sealing ring. The valve body defines a fluid-directing surface extending around the fluid passage between the inlet and the sealing ring to define an annular clearance which tapers towards the sealing ring and becomes narrower than the annular gap. When there is a pressure drop across the valve and before the closure member is moved to fully open the valve, material flowing through the valve experiences a dynamic pressure rise towards the circumferential gap, decreasing flow velocity and wear.

摘要： The present invention relates to a particle transfer system and a particle transfer method which allow preciously-weighed particles to smoothly pass through a vertically-provided vertical pipe of a transfer line when powder-type particles are transferred along the transfer line, and which prevent the particles from remaining or stagnating in the vertical pipe. To this end; the particle transfer system includes a particle transfer unit including at least one from among: a first transfer unit for transferring the particles in correspondence to first transfer information; a second transfer unit spaced from the first transfer unit to transfer the particles in correspondence to second transfer information, which is the same as or different from the first transfer information; and a third transfer unit spaced from the first transfer unit and the second transfer unit to transfer the particles in correspondence to third transfer information, which is the same as or smaller in amount than the first transfer information or the second transfer information.

摘要： In one embodiment, a pneumatic distribution system configured to distribute a granular product to an agricultural implement includes a first pressure sensor, a second pressure sensor, and a controller. The first pressure sensor is configured to be fluidly coupled to a storage tank configured to store the granular product and positioned upstream of the meter roller. The first pressure sensor is configured to output a first signal indicative of a first static pressure in the storage tank. The second pressure sensor is configured to be fluidly coupled to a component of the pneumatic distribution system, downstream of the meter roller. The second pressure sensor is configured to output a second signal indicative of a second static pressure downstream of the meter roller. The controller is communicatively coupled to the first pressure sensor and to the second pressure sensor. The controller is configured to determine a pressure differential, wherein the pressure differential is the difference between the first static pressure and the second static pressure. The controller may also be configured to generate a first warning when the first static pressure is below a threshold value and output the first warning to an operator interface, generate a second warning when the pressure differential is below a desired range and output the second warning to the operator interface, and generate a third warning when the pressure differential is above the desired range and output the third warning to the operator interface.
