1Q941H-16C DN80 hard sealed cast steel electric flange ball valveIntroduction:
Q941H-16C DN80 hard sealed cast steel electric flange ball valveThe fluid resistance is small and has low flow resistance (actually zero). Ball valves generally have two structures: reduced diameter and non reduced diameter channels. Regardless of the structure, the flow resistance coefficient of ball valves is relatively small. Especially for the so-called full flow type, which refers to ball valves that do not shrink in diameter, due to their channel diameter being equal to the inner diameter of the pipeline, the local resistance loss is only the frictional resistance of pipelines of the same length, that is, among all valves,Analog controlled electric ball valveThe flow resistance is small. In rocket launch and testing systems, it is required that the resistance of the conveying pipeline be as low as possible. There are two ways to reduce the resistance of pipeline systems: one is to reduce the fluid flow rate, which requires increasing the pipe diameter and valve diameter. This often has a negative impact on the economy of pipeline systems, especially for low-temperature transportation systems(Liquid hydrogen) is extremely disadvantageous; One is to reduce the local resistance of the valve, therefore, ball valves naturally become the best choice.

IIQ941H-16C DN80 hard sealed cast steel electric flange ball valveFeatures:
(1) Has low flow resistance (actually 0);
(2) Because it does not get stuck during work (in the absence of lubricants), it can be reliably applied to corrosive media and low boiling point liquids;
(3) Can achieve sealing within a larger range of pressure and temperature;
(4) It can achieve fast opening and closing, with some structures having an opening and closing time of only 0.05~0.1 seconds, to ensure that it can be used in the automation system of the test bench. When quickly opening and closing the valve, there is no impact during operation.
(5) The spherical closure can automatically locate at the boundary position;
(6) The working medium is reliably sealed on both sides;
(7) When fully open and fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface;
(8) Compact structure and light weight make it a reasonable valve structure for low-temperature medium systems;
(9) The valve body is symmetrical, especially the welded valve body structure, which can well withstand the stress from the pipeline;
(10) The closure component can withstand the high pressure difference during closure.
(11) The ball valve with a fully welded valve body can be directly buried underground, preventing the valve components from being corroded. Its high service life can reach 30 years, making it an ideal valve for oil and gas pipelines.

IIIQ941H-16C DN80 hard sealed cast steel electric flange ball valveCharacteristics of daily use
1The overall valve body of the electric ball valve has no pipe joints, so it is not affected by pipeline or bolt stress, and because the valve body does not have pipe joints, the pressure shell will not be subjected to pressure'Mutation';
2Electric ball valves are generally equipped with V-shaped valve bodies, which can ensure the control accuracy of electric ball valves even in low flow or high viscosity media;
3The leak proof and durable valve seat of the electric ball valve is lined with stainless steel inner core PTFE cup or O-ring seal, made of large section tungsten cobalt hard alloy, and its structure is further strengthened by alloy corrugated springs;
4When the valve of the electric ball valve is closed, a wedge-shaped shear effect is generated between the V-shaped notch of the electric ball valve and the valve seat, which has a self-cleaning function to prevent the ball core from getting stuck. This electric ball valve is particularly suitable for situations where pipelines are scaled, frozen, or have fiber and particle solids.

The handle on the handwheel and motor rear cover (hereinafter referred to as the motor handle)The switching between manual and electric positions is flexible, and it can be reliably positioned at the designated position. The handwheel can rotate freely in the electric position. After inspection, be sure to reset the handwheel and motor handle to "electric".
4. Connector inspection
Each plug and socket should be installed firmly and the contact should be secure. After removing the plug, check that there are no defects such as rust or deformation that affect the contact of each contact.
5. Lubricating oil inspection inside the gearbox
Clean lubricating oil should be added to the gearbox, and the oil level should not be lower than the lower limit of the oil gauge. Otherwise, lubricating oil should be injected from the lifting ring hole.
