stainless steel tube fitting

Type stainless steel needle valve working principle is introduced, as you know, the effect of any valve for cutting fluid. Depending on the valve core, can be divided into cut-off valve, gate valve, plug valve, ball valve, butterfly valve, stainless steel needle valve and so on. Stainless steel needle valve type than any other type of valve that can tolerate more pressure, sealed performance is good, so generally used for small flow, high pressure gas or liquid medium sealing. Type stainless steel needle valve and pressure gauge is used the most appropriate. The general type stainless steel needle valve type screw thread connection. Nominal pressure: PN2.5 PN4PN6. 4 pn16pn32mpa: nominal diameter DN5 ~ DN25 applicable medium: oil, water, gas and other non corrosive or corrosive medium applicable temperature: - 20 ℃ ~ + 440 ℃ -- 70 ℃ ~ 240 ℃ 540 ℃ 570 ℃ or less or less manufacturing materials such as: 20 #, 1 cr18ni9ti, 304, 316, 316 l, 12 cr1mov, etc.
Type needle valve is a valve can be precisely adjusted use widely, such as flame cutting with the cutting distance, the flame temperature adjustment knob is the needle valve, instrument type needle valve is an important part of stainless steel tube fitting the meter in the piping system, mainly cut-off valve and ball valve, its function is used as open or cut off the pipeline path. Any action for cutting fluid of the valve.. Depending on the valve core, can be divided into cut-off valve, gate valve plug valve, ball valve, the disc valve, needle valve, etc. Needle valve valve core is a very sharp cone, like the needle inserted into the seat, hence the name. Needle valve type than any other type of valve that can tolerate more pressure, sealed performance is good, so generally used for small flow, high pressure gas or liquid medium sealing. Type needle valve and pressure gauge is used the most suitable, general type needle valve type screw thread connection.
Type stainless steel needle valve, including body, located in the body of the valve core, as well as the product of the upper part of the connection of valve stem, valve core products including the hemisphere valve core and is stainless steel hydraulic fitting located at the upper hemisphere of the handle of the product. This product by changing the valve core structure, stability of the rotation direction of the ball, so as to stabilize the valve sealing performance and greatly improve the sealing effect and prolong the service life of the valve.
The second point, stainless steel needle valve in the disassembling rise very convenient. In order to facilitate cleaning, a lot of type stainless steel needle valve globe valve, ball valve installed in the process of installing and removing the is quite convenient, there is plenty of time to use less. So, the purchase and use type stainless steel needle valve is very wise behavior.
Stainless steel needle valve in the industrial production field can play a very important role, also can make a great contribution for development of national economy. However, many people are not very understanding of the stainless steel needle valve type this article. So, here is to introduce in detail. The first point, the stainless steel needle valve is an important part of stainless steel needle valve precision instruments. From the perspective of the specific classification of stainless steel needle valve type, there are about two cut-off valve and ball valve, for a lot of measuring instrument installation, applications is very extensive, so to speak. The current development situation, whether general petrochemical refining factory, or some other factory, will use to stainless steel needle valve type of this item.
