Q:What are the differences and advantages between O ball valve and V ball valve?
2 、 the switch is quick and convenientThe ball just rotated 90 degree is completed fully on or off, so it can achieve rapid opening and closing.3, good sealing performanceMost of the valve seat by four poly ethylene (PTFE) elastic materials, commonly known as soft sealing valve. Soft sealing valve has good sealing performance, roughness and machining precision and sealing surface of the valve is not very high.4, long lifeAs a result of polytetrafluoroethylene (PTFE or F4) has good self lubrication, and friction coefficient of the ball is small. Due to improved processing technology to reduce the ball roughness, thereby greatly improving the service life of the ball valve
Q:A connection wire for 21mm the other end is connected to 4 points inside the pipe joint ball valve
Four is 1/2=DN15, 21mm data is not accurate, if it is metric thread, provide tooth pitch and thread diameter.
Q:What does "S" mean by ball valve Q11S?
S should be the seal of the code, rather than the body of the code, S is a kind of high temperature resistant material 8202, "250 degrees high temperature, the sealing ring has the advantages of high strength, high wear resistance, the advantages of strong elasticity, therefore, reliable sealing, long service life, widely used in petroleum, chemical industry, pipe steam pipe the flow of a medium.
Q:Our factory has some ball valves in the direction of movement and normal ball valve is the opposite direction
Ordinary ball valve is the reverse turn off, the general ball valve without direction requirements. Each kind has the direction request, generally has the arrow or the nameplate explanation on the valve body.
Q:Into the tap valve, with globe valve or ball valve?
Water valve at home as far as possible not to use the form of valve, gate valve for water, slag better, shut down with the next valve and ball valve.
Q:The working principle of the track type ball valve
No wear and tear of switch:The ball core deviates from the valve seat and then rotates, eliminates the friction of the valve seat, and solves the abrasion problem of the seat of the traditional ball valve, gate valve and plug valve.Anti friction valve hard and dense cover:The surface of the ball core is welded with a hard polished sealing surface, which can ensure the sealing performance under very severe working conditions.
Q:Advantages and disadvantages of ball valves and scope of application?
First, the advantages and disadvantages of the ball valve1, advantages:Minimum flow resistance (actual 0);Because it is not stuck at work (without lubricant), it can be reliably applied to corrosive media and low boiling liquid;Complete sealing can be achieved in larger pressure and temperature range;It can realize quick opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so that it can be used in the automation system of the test stand. Quick opening and closing valve, operation without shock;The spherical closure can be automatically positioned at the boundary position;The working medium in the two-sided reliable seal;In the fully open and fully closed, the ball and seat sealing surface and the dielectric isolation, the high-speed media through the valve sealing surface will not cause erosion;It has the advantages of compact structure, light weight, it could be considered for most reasonable structure of the valve system of medium low temperature;To body symmetry, especially the welded body structure, can well withstand the stress from the pipe;The closure of parts can withstand the pressure differential.11;They all welded ball valve can be buried underground, so that the valve parts from erosion, the maximum life of up to 30 years, is the most ideal oil and natural gas pipeline valve.
Q:What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?
Features of pneumatic angle seat valve:1 、 visual position indication: it can be connected with limit switch or emergency manual device.2 、 easy to install: pneumatic head can rotate 360 degrees. One or two limit switches can be easily installed.3 、 advanced pneumatic controller: thickened engineering plastic shell, safe and reliable. Low wear piston structure with large capacity and low consumption. Self lubrication of internal components, maintenance free.4, with a variety of control methods: normally open, normally closed, double action.5. Require smaller pneumatic actuators: when the fluid flows over the stem, a smaller control head is optional.6, easy to connect: MAMUR standard connection, embedded metal connector.7, long-life Guide: Lease stem shaped Teflon (PTEE) sealed to avoid the import of stolen goods. Self lubrication, maintenance free. The stem is specially treated to ensure optimum fixation and automatically correct position.8. Without water hammer, the water hammer (water shock force) is absorbed when the fluid flows into the bottom of the valve stem.9, advanced valve body: flow is larger than ordinary angle block 30%, smaller size, better fluid flow pattern. 316 stainless steel body, Teflon seals, high temperature resistance, corrosion resistance. Life as high as seven million times
Q:Ball valve Q41f and Q11f difference, whether universal?
Q41 is flanged ball valve, Q11 is a threaded ball valve, the two connections in different forms, is not universal
Q:PPR gate valve, stop valve, dark valve, ball valve what is the difference between the gate valve and dark valve is a thing?
Dark valveThe blind valve is used to control the solar switch, and the double live ball valve connects the hot water pipe and the pipe, or the connection between the prefilter and the pipe, then it will be replaced in the future. The dark valve can be connected to the three pass.Globe valveBall valve (ball valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve for rotation of the valve.". Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
