In recent years, the rapid development of China's chemical industry, stainless steel valves to transport corrosive medium is widely used in chemical industry, more and more attention and use our. According to the data, in 2013 the stainless steel valves transaction information has increased greatly over the last year, enquiries business of stainless steel valves also increased, statistical data on these inquiries on stainless steel ball valve, stainless steel valves, stainless steel valves and interrogation of check valve at. Here we have the first of several valve


Working principle of 1 stainless steel ball valve, the love is by rotating the valve to the valve flow or occlusion, stainless steel ball valve is divided into several, a floating ball type, fixed ball type and screw type.


2, stainless steel valve also known as gate valve, which are widely used in chemical industry enterprises in the valve. Its principle is closed the gate sealing surface and the valve seat sealing surface highly smooth, divergence, attached with each other, can model prevent corrosive medium flows through the and relying on the top die, spring or gate, to strengthen the sealing effect, it is mainly in the line of cutting action. Advantages are: stainless steel gate valve fluid resistance small, open and close the province strong, can be used in the medium of two-way activity condition, no direction, full sealing surface is not easy to erosion, structural length is short, not only suitable for small valve, and appropriate big valve. Stainless steel valve by the valve stem threads are divided into two types, one is the rod type, two were dark bar. By gate structure, also divided into two categories, one is parallel, two is a form of.


3, stainless steel cut-off valve is also called the door, is the chemical industry uses a lot of the valve, it is popular, because the process of opening and closing the sealing surface friction between the small, more durable, highly open small, easy manufacture, convenient repair, not only suitable for the low pressure, and is applicable to pressure. Its principle is closed, relying on the valve bar pressure, the valve seat sealing surface and sealing surface tightly, to prevent media flow. One-way valve can only medium activity, directional device. Its length is greater than the valve structure, and fluid resistance, long-term operation, the sealing reliability is not strong. Valve is divided into three categories: straight-through, right angle and DC-type inclined valve.


4, stainless steel check valve is to rely on its own strength to fluid automatically open and close the valve, its role is to prevent the media back. Many of its title, such as check valve, check valve, single flow gate. According to the structure can be divided into two categories.


(1) stainless steel swing check valve: the valve seat around the pin shaft rotation, this type of valve has single, double valve and valve of the points, but the principle is the same. Suction end of the valve is the deformation of check valve, and its structure and the two by the valve the same, only the lower end is open, to allow water to enter the.


(2) stainless steel lift check valve: the valve body along the vertical centerline mobile. This type of check valve has two kinds: one kind is horizontal, installed on the degree of piping, body shape and the cut-off valve, the other is vertical, installed in the vertical pipe. In addition to these two kinds of dosage and stainless steel check valve, H71W wafer type check valve.
