Hydraulic valve


The gasification system hydraulic network is made gas central nervous strict implementation of computer signals from instruction and pass the power-driven hydraulic valve switching the flow of gas, to complete the cycle work. Kai hydraulic valve as the executing agency, the accuracy of the action closed in place, closed tight, open bore utilization, the opening and closing speed in place as well as reliability and operational efficiency. Have a direct impact on the safety and operational efficiency of the gas furnace running. To ensure and improve the hydraulic valve performance and quality requirements in the design of the valve for improved production and selection should mention grade, grade A.
Hydraulic valve from the gas-making application point of view, the process termed valve is fully open, full-closed valve, open through Close to closely. Its role is to switch the gas, to the conversion of the implementation phase, the formation of the cycle gas. With the The gas furnace continuous operation capabilities, the new production features the performance and quality of the valve higher requirements. Every manufacturer should pay extra attention performance and quality of the hydraulic valve. People only pay attention to whether the valve is locked and service life. And new ideas to see this issue believe that these two problems are of course important, but only emphasized these two aspects is not enough, but also pay attention to the valve opening degree, the effective diameter utilization.solenoid valve actuator
 This gasification technology development process, summarize discovered constraint on the operational efficiency of the gas furnace production capacity of new problems. Nearly 10 years of gas-making technological innovation, has been focused on the gas stove to expand the diameter and transformation of height to diameter ratio, as well as simplify processes bold pipeline. Designed to improve the efficiency of the gas, the production capacity of a single furnace so as to adapt to the ever-expanding system capacity, eliminating the rows of small stove, low thermal efficiency of the situation. However, some manufacturers expand the process piping, hydraulic valve optional incorrect. Resulting in resistance could not be reduced according to design requirements, not able to take full advantage of the benefits of investment. The reason is that the presence of optional hydraulic valve design make it open enough so occupied by the valve plate a certain channel area, resulting in resistance to the formation of the strangle hold phenomenon. To solve this problem, you must start from the design improvements. In order to effectively pass through the utilization, reduce resistance and improve operational reliability, lower failure rate target. Base plate valve, butterfly valve on the hydraulic gate valve, a series of improvements.3 way air valve
