。 3. The valve regulation performance is poorer. 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. Based on disc this way of moving, the seat of his change is relation with directly proportional valve stroke. Open or close the valve stem travel relatively short, and has very * blocking action, get this valve very fit as a medium truncated or adjust and throttling use. 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. 2. Small office by the valve stroke, opening and closing time is short. Disc polishing pillars plug and articulation, tightly closed by set plug in the column of two elastic tightly closed circle of successful implementation. 2) Once-through globle valve; In once-through or Y by the valve, 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. 2. Globle valve uncomfortable or used for larger particles, viscosity, easy to medium of coke. 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 Marine valves is very suitable for use as a body of occasions. Because open or close the valve stem travel relatively short, and have very can * truncation function, and because of the changes in the seat of his stroke proportional relationship with the disc, very suitable for traffic regulation. 【 Q 】 High pressure by the valve is superior to lack of' A 】 The valve stem axis and vertical seat tightly closed surface. 3. By the valve tightly closed, tightly closed between friction force is small, the survival of the fixed number of year is longer than the other. Lack of valve: 1. Open and close the valve fluid resistance is big, the required force is larger. Globle valve advantages are: 1. By the valve has simple structure, production and maintenance more convenient. The category by the valve according to the position of the stem turnbuckle points within a turnbuckle type of valve, turnbuckle type of valve. Media through the change of the flow direction of the valve, because the globle valve flow resistance is higher than other valves. In the valve, the valve disc and seat are generally of the preset on the basis of the principle of plunger. According to the flow of media, have straight through the valve, once-through ended by the end of valve and Angle type. 3) Plunger type of valve: this way, the valve is normal deformation of the valve. 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. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
