The connection form of the valve end faces is generally divided into three types: welded end connection, threaded end connection and flange end connection. The flange end is connected to the usual structural form of Zui.
1.1.1 Flange connection structure It is connected by means of flanges, gaskets and bolts. The flanged valves are easy to install and disassemble. It is suitable for a wide range of nominal diameters and pressures. The flange connected with the valve can be divided into flat welding flange, butt welding flange, socket welding flange, integrated flange, etc.; according to the sealing surface form, it can be divided into full plane flange, convex table flange, Concave surface flange,
Birch groove flange and ring groove flange. The choice of flange type and sealing surface form depends on the operating conditions.
Generally speaking, due to the low structural strength and rigidity, the flat welding flange is mostly used in working conditions where the operating conditions are relatively mild, such as low-pressure circulating water valves, general low-pressure compressed air valves, etc., Wenzhou Miller specializes in producing stainless steel people. Hole, stainless steel centrifugal pump, its advantages are low cost and easy installation. Butt welding, stainless steel manhole;
The flange has a good neck and conical transition structure, strength and rigidity, and can be non-destructively tested with the butt weld connection of the pipe, so it can be used in harsh conditions such as oil and gas and chemical media. Socket welded structures are commonly used for PN<10.MPa,
The DN is in 40 pipes. The sealing surface of the valve is also selected according to its operating conditions. The full-plane structure is often used in combination with the flat-welded structure. Under the condition that the condition is relatively mild, the boss surface is often used with the butt welding and socket welding structure, and its application is relatively wide. This can be used in harsh conditions such as oil and gas and chemical media. Socket welding structure is commonly used in PN town 10.MPa,
DN<40 in the pipeline. The sealing surface of the valve is also selected according to its operating conditions. The full-plane structure is often used in combination with the flat-welded structure. Under the condition that the condition is relatively mild, the boss surface is often used with the butt welding and socket welding structure, and its application is widely used. . The convex and concave surfaces are often used in the form of butt welding and socket insertion. The use of the groove surface is similar to that of the convex and concave surface, and the annular groove surface structure is often used in the form of a butt welded structure.
1.1.2 Threaded connection Threaded connection is a detachable connection, which is often used when it is not suitable for welding or needs to be disassembled. Threaded connection is divided into two types: internal thread connection and external thread connection. The internal thread connection usually processes the end of the valve body into a tapered tube or a straight tube female thread, and the pipe connected thereto is processed into a male thread of a tapered tube or a straight tube. The external thread connection is a valve that processes the end of the valve body into a male thread for easy installation and removal of the threaded end. 'The valve has a low threading strength and a strong seal compared to the welded joint method.
The non-invasive ventilator mode of this product can be used for adult patients who do not rely on invasive ventilation support, such as respiratory dysfunction, to provide ventilation assistance and respiratory support;
Products with high-flow heating and humidification mode can be used for humidification and oxygen therapy for adult patients with spontaneous breathing.
1.1 Valve end connection The end connection structure and size of the valve are very important for the installation and use of the valve. If improperly selected, it may cause the size or connection structure to be mismatched during the installation process, resulting in failure to install. Therefore, when selecting the valve, special attention should be paid to select the correct and suitable connection end face structure to ensure the smooth installation of the valve.
