There are several commonly used globe valves: 1) Straight-through globe valve 2) DC globe valve: In the DC or Y-type globe valve, the flow path of the valve body is inclined with the main flow path so that the degree of destruction of the flow state Than the regular valve to be small, so the pressure loss through the valve is also a small. 3) Angle stop valve: In the angle stop valve, the fluid only needs to change direction once, so that the pressure drop through this valve is smaller than that of the conventional structure. 4) Plunger globe valve: This type of globe valve is a variation of a conventional globe valve. In this valve, the disc and seat are usually designed based on the plunger principle. Polished valve plunger into a plunger connected with the stem, the seal is set by the plunger in the two elastic ring to achieve. The two elastomeric seals are separated by a collar, and the seal around the plunger is pressed firmly by the load exerted by the bonnet nut on the bonnet. Elastomeric seals are interchangeable and can be made in a wide variety of materials. The valves are mainly used to "open" or "close", but with a special form of plunger or special collar that can also be used to regulate flow .
A coffee grinder with a cone-knife grinder places a conical knife disk at the bottom of the machine, and then cooperates with the outer ring knife disk for grinding. The coffee powder produced in this way will be closer to granular, and at the same time, the water absorption path of the coffee particles will become longer, and it will take more time for the inside to contact the water, which will result in the coffee powder being released within the first time. The soluble substances are less, and the concentration will not be too high in a short time.
