Q: Standard and specification for pressure test of valves: (11) when the valve with drive device is tested and its tightness is tested, the sealing test shall be carried out by using the driving device to close the valve. For manual drive units, seal test shall also be done with the actuating closing valve.(12) the by-pass valve installed on the main valve after the strength test and the sealing test. The strength and tightness test of the main valve is carried out. The main valve should be opened when the closing member is opened.(13) iron valve strength test, the application of Pratia tapping valve and valve cover, check whether there is any leakage.(14) the valve test, in addition to the provisions of the plug valve to allow sealing surface oiling, other valves are not allowed in the sealing surface of the oil test.(15) when the valve pressure test, the blind plate on the valve pressure should not be too large, so as to avoid deformation of the valve, affecting the test results (cast iron valve if pressed too tight, will be damaged).(16) after the valve test pressure, should promptly remove the water and clean the valve, should also be prepared for the test record.

Q: I would like to ask how the valve entry, for a new pair, really difficult, what cutaway view, there are other, just contact the valve less than a week, and sometimes it is really difficult to understand. Forget the experienced teacher can be generous with your criticism to later, indebted forever, learn the valve Comrades some help.In a company CAD to relatives as soon as possible to a company, and then slowly improve, I do not know what is the request of the novice, and how to start as soon as possible, I am learning routine is: give me a set of valve design drawings, and then I paint it on, do not understand the structure and workshop look. I wonder if you have any good learning methods that can be referred to and supplemented by younger brother: Valve range can be very wide, each company to do valve products are not the same;According to the company's production capacity and technology,Valve parameters to:1, valve spool material,2, connection mode (thread, welding, flange, clamp, socket welding, fast loading, etc.),3 caliber,4, medium (water, steam, oil, gas, liquid, etc.),5, temperature (medium temperature, environmental temperature),6, pressure (MPa, LB, K, etc.),7, configuration (executor and its accessories);A lot of valve requirements and this almost. Can also be selected according to the ideal valve function of customers.Switching type:Ball valve, butterfly valve, globe valve, gate valve, needle valve, etc.Regulatory type:Pneumatic valve, electric valve (adjustable type can be divided into: regulating temperature, regulating pressure, regulating flow), and so on

Q: I would like to ask this valve (not too clear, is it possible to call the valve), what is the specific name of the professional? Where can I buy it?: Tiemuyu666, let's go inside and see if there's anything we need. For reference only

Q: What valves are needed on the construction site?: Depends on the actual size of the required diameter, how much work pressure, and then choose the right valve. Commonly used PVC, cast aluminum, cast iron; PVC cheap, commonly used in small diameter pipe, cast aluminum, cast iron is relatively expensive, high pressure.

Q: Chinese valve and a valve which is better?: Look what valve you use, ah, these two can be ah!

Q: How about the quality of FITOK valves?: The United States fitok valve is the main valve and needle valve, globe valve instrument and meter tube also do.The quality of foreign valves are still good. Everyone thinks French valves are better than American ones. But the price is not cheap

Q: The valve is rusty and can not be opened. What shall I do?: Spray with rust removing agent on the rusty rotating parts of the valve. Then use an afterburner to make a tentative rotation. Open it and turn it in the opposite direction. And then spray rust remover. Repeat this several times, and the valve will probably open. Seriously rusty valve, if it really can not open, simply replace it.

Q: Which valve can play a good regulatory role?: A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.

Q: What do you mean by the 16 bit coding of the valve type?: Valve model is by the type of valve, valve drive, valve connection, valve structure, sealing material, valve body material code to indicate.1. Valve types are Z- gate valve, P- drain valve, Q- ball valve, D- butterfly valve, J- stop valve, etc.;2, the valve drive mode code by letters said, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out3, the valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, valve structure code, for example: 0- 1- flexible gate valve, open bar wedge type single gate, 2- rising stem wedge gate, 3- parallel single gate, 4- double disk parallel, 5- dark pole single wedge gate, 6- dark bar wedge gate, dark 7- parallel single gate, 9- dark pole parallel gate;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber lining, Monel M-;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.

Q: How to open the gas valve with drawings: It's different from place to place. Some are pulled out half, and some are pulled out. Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all
