What is the performance of the stainless steel gate valve?

图片
Stainless steel gate valve performance: Stainless steel gate valves are widely used in chemical, petrochemical, petroleum, paper, mining, electric power, liquefied petroleum gas, food, pharmaceutical, water supply and drainage, municipal, mechanical stainless steel valves, equipment supporting, electronics industry, urban construction and other fields. The valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cutoff, regulation, throttling, check, diversion or overflow relief. Valves for fluid control, from the simplest shut-off valves to the most complex self-control systems, are available in a wide variety of sizes and sizes. The nominal diameter of the valve ranges from very small instrument valves up to 10m. Valves for industrial piping. The valve can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various c...

What is the meaning of a full-bore ball valve?

图片
The diameter (or diameter) is the common diameter of various pipe and pipe fittings. Pipes of the same diameter and pipe fittings can be connected to each other and are interchangeable. It is not the actual outer diameter or inner diameter of the pipe, although its value is close to or equal to the inner diameter of the pipe. In process piping systems, most valves are designed to limit the flow to a certain range by making the flow path or area of ​​the closure element smaller than the inner diameter of the line. Some ball valves can be designed such that their internal flow passages are of sufficient size to allow the flow to pass through without any significant restrictions. This ball valve is called a full bore ball valve because its internal flow path is equal to the full area of ​​the inlet and the full bore ball valve is primarily used for switching. And open circuit conditions. The reduced diameter ball valve is a valve that closes the flow rate of the component. The flow ...

What are the structural characteristics of the stainless steel knife gate valve?

A hard polytetrafluoroethylene scraper is installed on the upper end of th...

Stainless steel pneumatic ball valve manufacturers introduce the main features of the ball valve

图片
Stainless steel pneumatic ball valve main features 1. The manual part can be made of steel plate pressed handle or stainless steel cast handle. The handle has a limit structure, and the limit is set at the position where the valve is opened and closed. When the valve is used on the key device, the lock block is provided with a lock hole to lock the switch position to avoid misoperation. There are obvious opening and closing signs on the handle. 2. The valve stem is integrally forged and conditioned by Q641F stainless steel pneumatic ball valve manufacturer 182f (1cr13), and the hardness reaches hb220~250. The valve stem is connected to the handle through a flat key or a spline or a deed, which is versatile and easy to assemble and disassemble. The valve stem is provided with an anti-blowing structure. 3. The valve packing is made of braided, flexible graphite sealing ring or tetrafluoroolefin sealing ring, which makes the valve stem achieve reliable sealing under certain lubri...

The difference between high platform ball valve and ordinary ball valve

图片
The high-platform ball valve is an evolution of the ordinary ball valve. It has all the functions of a common ball valve, and is more beautiful and more refined than a normal ball valve. It is very convenient to install electric or pneumatic actuators with platform ball valves. It also saves costs without racks, improves production efficiency, and greatly improves the stability between valves and actuators. The performance is also very stable in use, it will not affect the application of the whole valve because the bracket is loose or the coupling clearance is too large. Or ordinary ball valves can’t do it. High-platform ball valves can be fitted with actuators directly, while ordinary ball valves require an upper bracket to hold the actuator. The high platform ball valve and the flange gate valve are the same type of valve. The difference is that the closing member is a sphere, and the ball rotates around the center line of the valve body to open and close the valve. The ball ...

Why stainless steel ball valves are widely used?

图片
Ball valves are mostly spherical in shape and generally have long switches for the user to manipulate the switches of the ball valves. With the development of technology, in addition to manual control of the switch, the current ball valve will be more efficient and convenient through automatic control. Due to its low cost, wide range of use, long life and wear resistance, ball valves are widely used in life, factories and other fields. So what is the principle of the  ball valve , so that it has such a strong advantage? The ball valve can control the internal partition or communication of the pipe in the pipeline or waterway. It can effectively control the circulation of liquids and gases. It only needs to turn the valve stem gently to control the flow, and the ball valve has good airtightness, so it is very convenient to use. Second, from its structure. Although the structure of the ball valve is simple, it can perform a good airtight function and can effectively control t...

What is the characteristic of the globe valve?

图片
The globe valve, also called the gate, is the most widely used type of valve. Due to its own performance, it is not only suitable for medium and low pressure, but also for high pressure. Next, stv will specifically introduce what is a globe  valve? What are the characteristics of the globe valve? A globe valve  is a valve that moves a closure (valve) along the centerline of the seat. Depending on the form of movement of the flap, the change in the seat opening is proportional to the flap travel. Due to the relatively short opening or closing stroke of the valve stem of this type of valve, and the very reliable cutting function, and because the change of the valve seat opening is proportional to the stroke of the valve flap, it is very suitable for the adjustment of the flow rate. Therefore, this type of shut-off valve is very suitable for use as a cut-off or adjustment and throttling. The most obvious advantage of the shut-off valve is that during the opening and closing p...
