The development prospect of the pneumatic trap industry is very good, because it brings many benefits to the enterprise when it is used, so it is deeply favored by customers. In order to let everyone know more about it, let's talk about the advantages of pneumatic traps, hoping to bring help to more people.
Nowadays, many people are still unfamiliar with some basic information about pneumatic traps, so it is necessary for us to briefly explain. In fact, the advantages of this pneumatic trap are that it can reach a pressure rating of 4500LB and a high temperature of 650 ℃, solving the high-temperature and high-pressure working conditions of special media such as steam, gas, coal slag, pulp, and the abrasion resistance of heavy oil and pulverized coal. In particular, its thermal spraying technology and supersonic spraying technology solve the reliability and integrity of spraying materials from the technical analysis of three factors: adhesion, porosity, and hardness, making the hardness of the ball and valve sealing surface of the valve seat reach above HRC78, improving the service life and wear resistance of the valve. Here, we also need to know that the valve rod seal of the pneumatic steam trap adopts a dynamic disc spring loaded structure, ensuring the sealing performance of the valve rod, reducing the friction of the valve rod packing, and reducing the switching torque. The upper part consists of a valve cover and a stuffing box, facilitating quick disassembly and on-site maintenance. The inclined valve stem structure and good flow path shape design make the medium close to a straight line, with a good Cv value, resulting in a lower pressure drop than other types.
The sealing of the pneumatic drain valve adopts a dynamic disc spring loading structure, ensuring the sealing of the valve stem, reducing the friction of the valve stem packing, and reducing the switching torque of the pneumatic drain valve. In particular, the sealing surfaces of the valve seat and the ball body adopt one-to-one diamond directional grinding, which makes the sealing more consistent, improves the sealing performance, and achieves zero leakage. In addition, we have mainly independently developed a high-temperature wear-resistant test rig to simulate severe operating conditions and conduct type tests on valves to ensure sealing performance and valve switching flexibility under high-temperature and high-pressure conditions. Adopt pneumatic, electric, electro-hydraulic linkage, turbine drive and handle operation. The manufacturer also uses a valve disc guided by the valve body cavity during production, which has two guide rings, upper and lower. The valve disc is guided up and down simultaneously, forming a piston type valve disc. The entire process of guiding water in the center cavity of the valve body can eliminate various kinds of jamming caused by improper force, especially scratches on the surface of the pneumatic drain valve, bending of the valve stem, vibration of the valve disc, and so on. The guide ring at the bottom of the disk passes through 90% of the fluid in a nearly linear manner, effectively eliminating all adverse reactions caused by side impacts.
After the above introduction, we also have a further understanding of the advantages of pneumatic traps. "When I see him again in the future, I won't feel strange, and I won't often encounter problems in the process of using him.". Okay, that's all for today.
