Q:For example, the knife gate valve, PZ73X-10C, DN50 torque is 5, torque is what role? What units?: The torque of the valve is the opening moment of the valve (valve torque): Newton meter.The opening moment, also known as the operating torque, is the most important parameter for selecting the valve actuating device. Opening torque is also a measure of the quality of the valve product is another important indicator, people in the evaluation of valve quality, commonly used valve opening light, flexible to describe it. In some advanced industrial countries in the pipeline valve standards, as one of the assessment indicators, and provides manual valve opening torque is not more than 360N ? M. More than this moment, it is necessary to consider the use of suitable driving devices (such as electric, pneumatic, hydraulic devices). Some manufacturers will open the torque printed in the product samples, user-friendly.

Q:What courses in the University involve valves?: Pressure vessel design, the valve is essentially a pressure to withstand the container. The valve can be understood fundamentally.

Q:The general signal valve installation, or other valve installation is not installed with the groove flange clamp hoop Yucca or direct way? What's the convenient way to install the following diagram? I don't understand. Neither groove, flange nor hoop. Thank you, sir!: The installation of the signal valve is in accordance with GB50261-2005The 5.4.6 signal valve shall be installed on the pipe in front of the flow indicator, and shall not be less than 300mm from the flow indicator.The other valve control valve installation, specification, type and location of installation shall comply with the design requirements, the installation direction should be correct, control valve should be clean, no blockage, no leakage; the main control valve should be added headstock logo, the control valve cover shall be provided to indicate position of the mark in the position.1. The installation of the exhaust valve shall be carried out after the pressure test and the flushing of the system pipe. The exhaust valve shall be installed at the top of the water distribution dry pipe and the end of the distribution pipe, and no leakage shall be ensured.2, the valve flow direction should be consistent with the direction of flow in the water supply pipe, water inlet side of the filter is installed, and should be installed in the control valve; the adjustable valve should be installed horizontally, the valve cover should be upward; the proportional valve should be installed vertically: when the level of installation, the valve orifice hole single breath we should double down, breathing valve whose orifice should be in a horizontal position.3 other control valve should be installed to keep a certain distance, to facilitate maintenance and management, installation of multifunctional pump control valve itself with pressure gauge, pressure gauge should be installed in the adjacent parts; import should be prevented in the back before the installation or use of the filter with filter backflow preventer, backflow preventer at both ends the valve should be installed separately, and at least one end of the flexible joint should be installed;

Q:How does the valve rust die?: Valve rust, and see what material, what type, the normal model iron, small, then change it directly. Large direct buy derusting lubricants, stainless steel just, then take the acid wash

Q:What valve is the VENT?: VENT generally use a check valve (resembling a screw, spring preload), also directly using the plugA two-way sealing type ball valve for example, in order to detect the leakage of the pressure after the end, also for pressing the cavity is convenient, usually in the body cavity external to the up position to open a checking leak, which is VENT.

Q:Can the gas valves be switched off regularly?: Can often switch, for example, after cooking, you can turn off the valve after cooking.

Q:Can other valves be used instead of 10?: An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.

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: May learn some basic knowledge of valves, learning in practice, relatively fast.

Q:Which valves are used in the power station?: Water supply system: butterfly valve, gate valve, eccentric hemisphere valveOil and gas system: stainless steel ball valve, stop valveFire fighting system: gate valve, relief valve, relief valve, sprinkler system

Q:What should be checked before using the valve?: The valve must be visually checked before installation1, valve opening and closing position should meet the following requirementsThe valve, the cut-off valve, throttle valve, regulating valve, butterfly valve, foot valve, the valve is in full closed positionPlug valves and ball valves should be in full open position? diaphragm valve should be in the closed position, and can not be too tight to prevent damage to the diaphragmCheck valves shall be closed and secured2, the valve shall not be damaged, missing parts, corrosion, nameplate shedding and other phenomena, and the valve body shall not be dirty3, both ends of the valve should be protected. Handle or handwheel should be flexible and light, and must not be stuck4, valve body casting, the surface should be smooth, no cracks, blisters, lock, pores, burrs and other defects; outside valve forging, the surface should be free of cracks, interlayer, double skin, scar defect
