Q:Is the ball valve the same as the float valve?
The answer upstairs is more accurate, I will add.1. ball valve: refers to the valve spool (seal components) for the ball shaped valve, collectively known as ball valves.2. float valve, that is upstairs to explain the kind of specific, you can refer to the toilet, which is used on the water supply device is this structure.The 3 threaded valve, threaded flange valve, valve flange welding flange or valve: This refers to the connection forms of body, such as your home with the water valve between the valve and pipeline is usually a threaded connection, then the other is threaded, welding, flange connection means.
Q:Is the drain valve the same as the ball valve?
Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight. Ball valve is the most suitable switch, shut-off valve used, V ball valve. Electric valve should pay attention to the pipe parameters, but should pay special attention to its use of environmental conditions, because the electric valve in the electric device is a mechanical and electrical equipment, the use of its state by its use of environmental impact. Under normal conditions, electric ball valves, butterfly valves in the following environmental use should pay special attention to.
Q:What's English for ball valves?
Check valve/ball vavle/globe valve (ball valve), there are three kinds of translation, see which you preferFast stainless steel ball valve, ball valve is evolved from the plug valve. It has the same rotation, 90 degrees lifting action, and the difference is that the cock body is a sphere and has a circular through hole or passage through its axis. The ratio of the sphere to the channel opening should be this, i.e., when the ball rotates 90 degrees, the spherical surface should be fully presented at the inlet and outlet, thus truncating the flow. The ball valve only needs to rotate 90 degrees of operation and very small turning moment can close tight. Full equality of the valve cavity for the media to provide a small resistance, through the flow channel. It is generally believed that the ball valve is suitable for direct opening and closing, but the development of the ball valve has been designed to make it throttling and controlling the flow.
Q:Maintenance of PPR pipe ball valve is live or hot melt?
The ball valve is defined with the ppR/PE hot melt plastic pipe connected with the ball valve hot melt connection, ordinary ball valves generally use the threaded connection or flange connection.Hot melt connection is widely used in PB pipe, PE-RT pipe and other new pipe connections.Hot melt connection has the advantages of simple connection, long service life and easy corrosion.PPR pipes can only be connected by hot melt. There is a dedicated connection PPR tube double union copper ball valve, ball valve is full of copper, on both sides with PPR live tab.Ball valve (in the field of marine engineering and ships should be cut-off 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 to rotate the valve movement.". 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.Ball valve was introduced in 1950s, with the rapid development of science and technology, production process and product structure of continuous improvement, in a short span of 40 years, has rapidly developed into a major valve category. In western developed countries, the use of ball valves is increasing year by year.
Q:What does one inch of an ice ball refer to?
Ball valve inch refers to the nominal diameter of the valve is 1 inches, that is, DN25 valves, mostly threaded connections.
Q:Ball valve Q41f and Q11f difference, whether universal?
Generic. The Q41F 4 stands for flanged connections, and the Q11F 1 represents the internally ribbed pipe
Q:Structure design principle of fire ball valve
The purpose of fire protection structure design of valve seat is:(1) effective guarantee in the fire accident, the upstream pressure medium as little as possible into the body cavity through the valve seat, thereby causing internal leakage and leakage. Ensure that fire accidents are not expanded by fire before the firemen arrive at the scene of the accident. After the firemen arrive at the scene, fire equipment can be used to quickly suppress the fire and eliminate fire accidents.(2) to make the structure of the product meets API6D specifications. Fire proof can be obtained through fire test.Fireproof design of valve seat:Set graphite in metal fire valve seat and valve body sealing rings; sealing set fireproof metal in the metal valve seat and ball room. The structure is shown in Figures 1 and 2.
Q:What's the diameter of the 4 point ball valve?
4 points is 0.4 inches, 1 inches =25.4 mm.Then the 4 point ball valve diameter is 10.16mm.
Q:Home tap water valve (ball valve) half open or well open, open half is not love rust live?
Open big, small, same, as long as the pressure is enough, enough flow does not matter. The effect is half open, with a sound.
Q:In the wet alarm valve usually kept under working condition, alarm test ball valve state usually is closed or open?Because the alarm performance test on the pressure switch and hydraulic alarm, can be tested by open test ball valve, the bar working condition, the valve is closed or open? If so, if there is a police situation, if the police? If it does, it doesn't always call the police Seek expert advice.
Should be normally closed, the test valve is only the experimental pressure switch and hydraulic alarm, water from the valve directly into the alarm line, the wet alarm valve does not move, but you open, it usually has been ringing
