Q:One stainless steel ball, two pieces, three pieces of difference, use
A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
Q:What is the difference between gas ball valve RQ11F-25P and ordinary stainless steel spike valve Q11F-25P?
Q11F-25P ordinary PTFE stainless steel ball valve, pressure grade 25MPaRQ11F-25P on both sides of the narrow, sealed PTFE stainless steel pressure grade 25MPa ball valve is the difference between the appearance of the other almost. Same use.
Q:What does copper ball valve type Q11F-16T mean?
Q11F-16T refers to the internal thread of copper ball valves, 16 kg pressureQ refers to the ball body; 1 refers to the internal thread connection; 1 refers to the straight through; F refers to PTFE sealing cover; 16 refers to 16 kilograms of pressure; T is the valve body material is copper material, and then add, the front two also answered very specific.
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:Electric ball valve installation need to pay attention to what?
3, valve installation should be detailed understanding of its performance and features; 4, valve installation space to ensure the ease of use, maintenance and repair simple. 5, in order to avoid loose screws, bolts of leakage, before use each fastening screws; 6, in the use of the process should pay attention to the use of medium pressure valve, such as temperature, so as to avoid damage to the valve; 7, such as the valve opening and closing in, should identify the reasons, troubleshooting, no knock, smashing etc. method of forced opening and closing.
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:What's the difference between T ball valve and L ball valve?
This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.
Q:Advantages of track ball valves
10, the valve refractory design, API, 6FA and API 607 standards. All valves are fire resistant and safe.The valve seat sealing surface., all metal seal structure, when the fire, still can guarantee the sealing medium leakage, stop.The flange. In stainless steel and graphite gasket, can meet the requirements of fire;The stuffing box is arranged. Flexible graphite packing, can lose the effect due to fire and other reasons in other packing flexible graphite packing to seal effect can meet the requirements of fire;11, the valve stem through the stem nut, valve cover, valve body, between the core of the ball formed a continuous circuit conduction, to achieve anti-static effect.12, in order to improve the reliability of the valve, safety and sealing capacity, to reduce the failure rate, the valve low-pressure air tightness does not depend on the seat spring to achieve.13, the stem and valve ball position by stem guide pin and stem to cut off the coordination to control, in order to ensure the stability of valve operation, stem guide pin for double guide pin, and stem guide pin can be removed and replaced from the outside.14, hand wheel or bearing fixed, use bolt or nut compression, do not use elastic clasp.15, the valve installation size and the existing valve consistent, with good interchangeability.
Q:What's the meaning of the double ball valve in the double ball valve?
By means of "union", the "live" means that the two ends of the valve are connected by a live joint
Q:What domestic PPR ball valve can withstand acid and alkali?
Yue Yue PPR ball valve products are made of pure raw materials, mainly used in water supply and other plastic piping systems for industrial use. You can rest assured that the use of Hong Yue products
