Fan shaped valve, as the name suggests, its core operating component - valve disc, is shaped like a fan. It is not simply moving up and down, but opening or closing the flow channel through clever rotation. This design makes it particularly adept at fine flow regulation, not just fully on or off, making it a "star component" in industrial scenarios that require precise process control.Working principle: precise control between rotationsIts working method is intuitive and clever:When closed: The valve disc rotates 90 degrees, like a door completely blocking the middle of the pipeline, firmly blocking the fluid.When opening and adjusting: the valve disc rotates back from this position. The larger the opening, the more spacious the channel through which the fluid passes. By precisely controlling the rotation angle (such as 30 degrees, 60 degrees), it is possible to achieve linear and stepless control of flow from subtle to complete, just like controlling the speed of a steering wheel.Simply put, a sector valve is like a finely adjustable angle "valve" that speaks with a rotating angle, accurately commanding the flow of fluid in the pipeline, whether it is more or less.

Manual ventilation butterfly valveThe working principle of manual ventilation butterfly valve is mainly through manual operation, which rotates the butterfly plate inside the valve body to control the opening and closing of the valve and regulate the flow rate of the medium.The structure of the manual ventilation butterfly valve is welded using a centerline butterfly plate and a short structural steel plate, so there are no connecting rods, bolts, or other components inside. Therefore, there will be no component problems during use, resulting in a low failure rate. It is very convenient to use and is a reliable valve device. And because its sealing system adopts metal sealing, although the sealing effect is not as good as elastic sealing, its service life is longer than elastic sealing, and it has the characteristic of high temperature resistance. So it has a wide range of applications in industries such as building materials, electricity, metallurgy, etc. In medium conveying pipelines with temperatures not exceeding 300 degrees, perfect connection and closure adjustment can be achieved. This butterfly valve can also be customized according to customer needs, which is very user-friendly. Manual ventilation butterfly valve structure: mainly composed of valve body, valve stem, disc plate, and sealing ring. The valve body is cylindrical in shape, with a short axial length and a built-in disc plate. Working principle: The disc plate is driven by the valve stem, and if it rotates 90 degrees, it can complete one opening and closing. By changing the deflection angle of the disc, the flow rate of the medium can be controlled. The main sealing component is the sealing ring, and its material is commonly used according to the purpose and medium. There are two types of ventilation butterfly valves: clamp butterfly valves and flange butterfly valves

Strength property The strength of a valve refers to its ability to withstand the pressure of the medium. Valves are mechanical products that withstand internal pressure, therefore they must have sufficient strength and stiffness to ensure long-term use without rupture or deformation. Our company produces manual globe valves, hydraulic globe valves, globe valves, manual metallurgical valves, hydraulic metallurgical valves, pneumatic metallurgical valves, and electric metallurgical valvesSealing performanceThe sealing performance of the valve refers to the ability of each sealing part of the valve to prevent the leakage of the medium, which is the most important technical performance index of the valve. There are three sealing parts of the valve: the contact between the opening and closing parts and the sealing surface of the valve seat; Packing with the valve stem and stuffing box; The connection between the valve body and the valve cover. The leakage in the first place is called internal leakage, which is usually referred to as lax closing, which will affect the ability of the valve to cut off the medium. For cut-off valves, internal leakage is not allowed. The latter two leaks are called external leaks, that is, the medium leaks from inside the valve to outside the valve. Leakage will cause material loss, pollute the environment, and cause accidents in serious cases. For flammable and explosive, toxic or radioactive media, leakage is not allowed, so the valve must have reliable sealing performance.Flowing mediumAfter the medium flows through the valve, there will be a pressure loss (the pressure difference before and after the valve), that is, the valve has a certain resistance to the flow of the medium, and the medium will consume a certain amount of energy to overcome the resistance of the valve. From the perspective of energy conservation, when designing and manufacturing valves, the resistance of the valve to the flowing medium should be reduced as much as possible.Opening and closing force and opening and closing momentOpening and closing force and opening and closing moment refers to the force or moment that must be applied to open or close the valve. When closing the valve, it is necessary to form a certain specific pressure seal between the opening and closing parts and the head sealing surface, and at the same time to overcome the friction between the valve stem and the packing, the valve stem and the screw thread between the valve stem and the nut, the valve stem end support and other friction parts, so a certain closing force and closing torque must be applied, the valve in the opening and closing process, the required opening and closing force and opening and closing torque are changed. Its maximum value is at the final instant of closing or the first instant of opening. The valve should be designed and manufactured to reduce its closing force and closing torque.Opening and closing speedOpening and closing speed is expressed by the time required for the valve to complete an opening or closing action. Generally, there are no strict requirements for the opening and closing speed of the valve, but some working conditions have special requirements for the opening and closing speed, such as some requirements for rapid opening or closing, to prevent accidents, and some requirements for slow closing, to prevent water strikes, etc., which should be considered when selecting the valve type.Action sensitivity and reliabilityThis refers to the sensitivity of the valve to changes in medium parameters. For throttle valves, pressure reducing valves, regulating valves and other valves used to adjust medium parameters, as well as safety valves, traps and other valves with specific functions, their functional sensitivity and reliability are very important technical performance indicators.Service lifeIt indicates the durability of the valve, is an important performance indicator of the valve, and has great economic significance. It is usually expressed by the number of opening and closing times that can ensure the sealing requirements, and can also be expressed by the use time.
