- Q:Pressure gauges, safety valves and other safety accessories and the cylinder can be installed between other valve components,
- The lower part of the pressure gauge installed water pipe, there are water, avoid high temperature, medium pressure gauge contact directly cause damage, so regular cleaning, in order to avoid congestion, three way plug function is used for flushing, please see "how to operate them.".
- 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:Add a valve on the trachea, when the valve behind the use of gas units,
- It seems that this is not a valve, it should belong to the flow switch
- Q:What do letters represent in the QF-2 and PX-32 valve models?
- Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!
- Q:How do you calculate the flow of the valve?
- Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
- Q:Yongde jiekelong valves and valves of the good faith
- Interior decoration is the most cost-effective brand, switches, sockets, Zhejiang, Yongkang, France and Germany electrical appliances. Plumbing valve, Zhejiang, Yongde, Yongkang letter. Bathroom accessories Fujian Nanan Jomoo bathroom.
- Q:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
- The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.
- Q:What is the KVS in the valve parameter?
- The valve Kvs is to reflect the passing capacity of the valve, which is defined as the pressure at both ends is 1bar, through the flow of the valve, Kvs is a characteristic parameter of the valve, and valve structure, is a constant value.
- Q:Who knows what the DE stands for in the valve DE50?
- Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.De is the nominal diameter, that is, the outer diameterGenerally speaking, from small to large specifications are as follows de (mm)De20, de25, de32, DE40, de50, de63, de75, de90, de125, de110De160 de200 de250 de315...... Until de800
