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:How can I install the water pipe valve?
1. Prepare the glue and saw blade. Disengaging bracket.2, using a hand saw from the valve mouth (spool near) transverse incision.3, the center will be on the move, the longitudinal incision, be careful not to damage the inner tube.4. Clean the pipe mouth, pipe and new valve coating, install the valve.Turn left and turn right |
Q:What is the difference between valve j941H-40 and j41H-40?
The difference is that one drive is electric, one is transmission, and the other is manual."Valve design manual" showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)More than one, 9, 9 fingers, electric, more than an electric.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:Where is the hydrant main valve?
The fire hydrant generally has two sources, one is from the roof water tank, a water pump is from the housing, maintenance, should close the fire hydrant located on the riser inlet valve tube under the ring, generally located in the top and bottom, and then discharge, when the valve cannot be closed, the proposed closure of replenishment valve and the pressure stabilizing device of water tank, fire pump in manual state, drainage after maintenance. Watch out for fire.
Q:What are the general types of valves?
Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Function and use(1) cut off categories: such as gate valve, globe valve, plug valve, ball valve, butterfly valve, needle valve, diaphragm valve and so on. Cut off valve, also known as closed-circuit valve, stop valve, whose role is to connect or cut off the pipeline medium.Check valves, also known as check valves or non-return valves, check valves belong to an automatic valve, its role is to prevent the pipeline medium backflow, to prevent the pump and drive motor reversal, as well as the leakage of container media. Pump water off the bottom valve check valve also belongs to class.The function of the relief valve is to prevent the medium pressure in the pipeline or device from exceeding the required value so as to achieve the purpose of safety protection.Control valve, throttle valve and pressure reducing valve, its role is to regulate the media pressure, flow and other parameters.(2) vacuum type: such as vacuum ball valve, vacuum flapper valve, vacuum air charging valve, pneumatic vacuum valve, etc.. Its function is to change the direction of the air flow in the vacuum system, adjust the air flow rate, cut off or connect the vacuum system of the pipeline, and the component is called the vacuum valve.(3) special uses such as pigging valves, vent valves, drain valves, exhaust valves, filters, etc.. The exhaust valve is an essential auxiliary component in the pipeline system. It is widely used in boilers, air conditioners, petroleum, natural gas, water supply and drainage pipelines. Often installed in the commanding heights or elbows, etc., to exclude excess gas pipeline, pipe road to improve the use of efficiency and reduce energy consumption.
Q:Valve connections - two how do different connections work?
The connection of two different connection forms is achieved by a transition conversion connector
Q:Can the angle valve of York central air conditioner be replaced by other valves?
Definitely. But I want you to tell me what you're doing, or give me a picture. I can give you some advice
Q:Valve pressure test
The standard is different, the test is not the same, what kind of valve you, a domestic valve only do stress testing, in fact, the pressure can generally be guaranteed, many are bad at high temperature or life testing above
Q:Heating pipes, in addition to the living room,
There is gas, causing water not to cycle, give up on the cure! Are you single family control?Single family control, the general bedroom and living room is not all the way, the living room, this way, the vent valve in the toilet, I was on the road in the balcony! The bleeder valve, is made of copper tube in the device above two, as long as can step in his place, the bleeder valve with a small angle, feet above a needle, with a needle to drill a well, there is a long time not float, a gas exhaust out that leads to water circulation,Why do you put a little while, the water is hot, a little cooler, the water does not cycle, is dead water, can not cool it?I am building plumbing, believe me, yes, these are some common problems, especially on the top floor!
Q:How to quickly identify the types of valves?
The "Practical Handbook" valve design on the valve structure, with precision, surface roughness and typical design standard, the valve has hundreds of models, and continue to have a new valve, see a written one, is shorthand
