Wide flange steel ball Product Description: Q41F wide flange ball, small size, easy installation features, but also has the advantage of national standard flanged full bore easily leak in one fell swoop changed little in the past way flow valve flange, easy leak solid illness, but also solve the GB flanged ball valves too bulky weaknesses, but the body can be refined with the casting process, elegant appearance. Full bore, large diameter capacity, connection dimensions conform to standard wide flange ball is expected to be widely used on an increasing number of channels. Wide flange steel ball is a sphere with a circular channel for opening and closing pieces, turning ball with stem to achieve open and close the valve action. Valve opening and closing parts is a hole in the sphere of rotation around the vertical axis of the channel in order to achieve the purpose of opening and closing of the channel. The main supply valve to open and close with the medium of pipes and equipment. Wide flange steel ball valve main purposes: carbon steel wide flange ball valve is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other types of systems over the water, gas, steam and some corrosive liquids and other media. Carbon steel flange ball wide scope: ☆ pass through the range: DN15 ~ DN100 ☆ pressure range: 1.6MPa ~ 2.5MPa ☆ Temperature range: -10 ℃ ~ 120 ℃ ☆ range of media: water, oil, gas, gas, etc. . Wide flange steel ball valve main advantages are as follows: 1. small fluid resistance. 2. The structure is simple, relatively small size, light weight, ease of maintenance. 3. 4. Good sealing performance flows from mounting direction restriction, the media can be arbitrary. 5. No vibration, noise. Wide flange steel ball valve installation and maintenance should note the following: 1. To leave the valve handle can not be used to rotate the position 2. throttle. 3. Ball belt drive mechanism should be installed upright. Ball Category: Ball form of the structure can be divided into: floating ball, fixed ball, elastic ball and valve seals; by channel type can be divided into straight, angular style and three-way, etc., can be divided into three-way T-shaped and L-shaped two kinds. According to the connected party workers can be divided into a threaded connection, flanged and welded three.
