。 According to the flow of media, have straight through the valve, once-through ended by the end of valve and Angle type. 3. The valve regulation performance is poorer. Because open or close the valve stem travel relatively short, and have very good truncation function, and because of the changes in the seat of his stroke proportional relationship with the disc, very suitable for traffic regulation. Commonly used by the valve has the following kinds: (1) Angle type of valve; Only need to change in Angle type of valve, fluid direction at a time, cause in after the valve pressure drop is smaller than normal structure by the valve. Lack of valve: 1. Open and close the valve fluid resistance is big, the required force is larger. Two elastic tightly closed circle separated with a thimble, and pass by the bonnet nut to load on the cover tightly closed circle around the plunger pressure. 2. Small office by the valve stroke, opening and closing time is short. By the valve once in an open state, the seat and disc will no longer have contact between tightly closed surface, so it tightly closed surface mechanical wear and tear is small, because most of the valve seat and valve disc is easier to repair or change closely enclosed components don't need to put the whole valve when removed from the pipeline, that for valves and pipeline welding is very suitable for use as a body of occasions. Media through the change of the flow direction of the valve, because the globle valve flow resistance is higher than other valves. 【 Q 】 The valve's unique place with insufficient place 【 A 】 The valve stem axis and vertical seat tightly closed surface. 3) Plunger type of valve: this way, the valve is normal deformation of the valve. 3. By the valve tightly closed, tightly closed small friction between the surface and a longer survival duration of Marine valves. Open or close the valve stem travel relatively short, and has very good cutting action, get this valve very fit as a medium truncated or adjust and throttling use. 2) Once-through globle valve; In once-through or Y by the Industrial Valves, the valve port from the mainstream way into a diagonal lines, so the flow condition of damage is much greater than normal by the end of valve, so after the valve of the corresponding small pressure loss. In the valve, the valve disc and seat are generally of the preset on the basis of the principle of plunger. 2. Globle valve uncomfortable or used for larger particles, viscosity, easy to medium of coke. The category by the valve according to the position of the stem turnbuckle points within a turnbuckle type of valve, turnbuckle type of valve. Disc polishing pillars plug and articulation, tightly closed by set plug in the column of two elastic tightly closed circle of successful implementation. Globle valve advantages are: 1. By the valve has simple structure, production and maintenance more convenient. Based on disc this way of moving, the seat of his change is relation with directly proportional valve stroke. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
