Check valve manufacturer-Weituo deliberately builds a brand

Cock check valve manufacturers, gate valve overview The opening and closing parts of gate valves are gates. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, which is not suitable for adjustment and throttling. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce slight deformation to improve its manufacturability and compensate for the deviation of the sealing surface angle during the processing. The plate is called an elastic gate. The structure is compact, the shape is be

Wei Tuo is attentive and thoughtful-Hubei grooved gate valve specifications

So far, the daily production capacity of the German Weituo company's production line is 300 tons. The project's hardware and software level and overall production capacity are in a leading position in China, and it is one of the few large-scale medium and high-pressure valve production bases in China. The base has built a 35,000-volt dual-circuit substation. From casting, machining, assembly, and painting of valves, everything is done independently in the Cast Steel Industrial Park. Advanced equipment and strict quality control have basically eliminated product defects such as pores, sand holes, fire extraction, fire, floating cores, wrong boxes, and expanded boxes. Germany Weituo applies the international advanced resource management concepts to the group management model, and implements a multi-factory and multi-industry management structure.

Introduction to the distinction between rising stem gate valve and dark stem gate valve

Weituo Weituo Fluid Equipment WATO Wuhan Weituo Fluid Control Equipment Co., Ltd. The gate valve is a gate for opening and closing parts. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate, and the sealing surface is usually welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc.

The manufacturer takes you to understand the advantages of bellows globe valves

Weituo Weituo Fluid Equipment WATO Wuhan Weituo Fluid Control Equipment Co., Ltd. Bellows globe valve is a kind of globe valve. The globe valve is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. The opening and closing part of the stop valve is a plug-shaped valve disc, and the sealing surface is flat or conical. The valve disc moves linearly along the center line of the valve seat. The bellows globe valves produced and sold by Zhongzhi Valve are made of carbon steel, stainless steel, etc. The operation methods can be manual, bevel gear, electric, pneumatic and so on.

How to avoid butterfly valve failure during use

Weituo Weituo Fluid Equipment WATO Wuhan Weituo Fluid Control Equipment Co., Ltd. The butterfly valve is a widely used valve. It originated in the 1930s. The butterfly valve is a 90-degree switch or a valve that regulates flow. Due to its simple structure, small size, light weight, and simple operation, the butterfly valve is It can be applied in many working conditions. Butterfly valve connection methods include flange connection, wafer connection, welding connection, etc. Different materials can also be selected according to different working conditions. The butterfly valve can be made of cast iron, cast steel, stainless steel, etc. Of course, it is inevitable that there will be malfunctions during use, so how should we try to avoid malfunctions in the use of butterfly valves? Let's take a look together.

What are the characteristics of the wide application of ball valves?

Weituo Weituo Fluid Equipment WATO Wuhan Weituo Fluid Control Equipment Co., Ltd. ball valve is a new type of valve that came out in the 1950s. In just over 30 years, it is one of the valve varieties that have developed rapidly in the past ten years. In the pipeline, it is mainly used to cut off, distribute and change the flow direction of the medium. The ball valve designed as a V-shaped opening also has a good flow adjustment function. The ball valve can be closed tightly

Understand the installation requirements of the safety valve on the boiler

Weituo Weituo Fluid Equipment WATO Wuhan Weituo Fluid Control Equipment Co., Ltd. The safety valve is a special valve whose opening and closing parts are normally closed under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, the medium is discharged to the outside of the system to prevent the medium pressu

In-depth understanding of the structural characteristics of the lower plate gate valve

Flat gate valve is a member of the gate valve family, which is the same as the wedge gate valve; its main function is to control the on and off of the pipeline, not to adjust the flow of the medium in the pipeline. The advantages of the flat gate valve: small fluid resistance, labor-saving opening and closing, short structure length, no restriction on the flow direction of the pipeline medium, etc. The flat gate valve is suitable for oil, natural gas, water, oil and other pipelines with Class150~900/PN1.0~16.0MPa and working temperature of -29~121℃ to cut off or connect the medium in the pipeline. Product structure characteristics of flat gate valve:
