FAQ

The expert can tell me how to install this valve, and what fittings to use on both sides

If the process permits, you can first weld on both sides of the flange, modified into a flange butterfly valve, and then installed on the pipe, easy to overhaul later

How do I open the gas valve?

1, the natural gas valve "Shun" pipeline is open, "horizontal" as "off". The following is to open the valve diagram?Turn left and turn right |?2. Attachment: the function of the main facilities of natural gas is:Valve well: a device for installing a valve to control an underground gas pipeline. The building regulation boxes or regional station: the device will be adjusted to the user requirements of medium pressure natural gas pressure. The riser valve: General in the first floor of the building, the kitchen are arranged on the pipe, the vertical pipe used to control all users. Indoor main valve: also known as meter front valve, is the home gas main switch, placed in front of the gas meter, used for natural gas on-off. This valve "opens" the pipe to be opened, "cross" is the pass. Gas meter: IC card intelligent gas meter and user gas consumption measuring device. The front of the stove valve: located in the table, the control valve of gas stove, gas should be closed after the end of time. The IC card is convenient for users to purchase gas use.

What do O and S mean on the valve?

Generally used in process valves, operating conditions required to open and close, especially in the case of pneumatic actuators installed, the loss of power and gas supply valve when the state

Various types of valves, with the continuous improvement of various types of equipment, process, the types of valves are still increasing. But generally speaking, they can be divided into two major groups.(1) automatic valve. A valve that moves by itself depending on the capacity of a medium (liquid, air, steam, etc.). Such as safety valve, pressure reducing valve, check valve, steam trap, air trap, emergency shut-off valve and so on. (2) drive valve. A valve operated by hand, power, hydraulic, or pneumatic. Such as gate valve, globe valve, throttle valve, regulating valve, butterfly valve, ball valve, plug valve and so on.

In the fire drawing, what valve does the following valve represent?

1, fire drawings, the following valve signal valve and alarm valve.2 、 signal valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve. The output signal is stable and reliable for a long time.3 、 alarm valve products are wet alarm valve, dry alarm valve, rain alarm valve, pre acting alarm valve and so on. It is the core component of wet automatic sprinkler system. The water enters from the bottom of the valve body and closes the check valve through the dead weight inside the valve body to form a standby system with water pressure. The high pressure gauge indicates the system pressure, and the low pressure gauge indicates the pressure outside the system. When the protected area fire, high temperature make the nozzle temperature sensing element of blast nozzle sprinkler system, pressure drop, the valve opens, water flows continuously into the system, the nozzle opening, continuous sprinkler. At the same time, a small amount of water enters the alarm tube from the inner hole of the valve seat, passes through the filter, the retarder, and then pushes the hydraulic alarm to alarm. In addition, after the pressure switch is activated, the electrical signal is issued and the make-up water is started.

What's the material of j41h-16p's valve?

According to the provisions of the JB/T 308-2004 valve type programming method:J== stop valve4== flange type1== through channelH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaP== body material: chrome nickel stainless steel. As of 304

Valve difference

Valve difference, or you should ask the classification of valves, valve classification, there are several sub methods, some according to the model, and some are by use, then each kind of valve is divided into several categories and models. Take the trap for example, it is a kind of valve, and then it is divided into steam traps, air traps, float traps, and so on. If you really want to know the difference between the valve you search the Internet under the classification of the valve, there are a lot of articles, or you directly to the trap inside www.ssfmsh find an article on the valve type article, can not give you a specific address, is not allowed here. You work hard, go find kazakhstan. I hope my answer will be helpful to you.

How can the material be checked by valve approach? What experiments do you need?

May refer to the valve pressure test principle and the pressure test matters needing attention.(1) in general, the valve shall not be subject to strength test, but the body and bonnet shall be subjected to strength tests after the repair of the valve body and bonnet or corrosion damage. For the relief valve, the constant pressure and seat return pressure and other tests shall be in accordance with the specifications and the relevant regulations.(2) the installation of the valve should be done for strength and tightness test. Low pressure valve sampling 20%, if not qualified should be 100% of the inspection; medium and high pressure valve should be 100% of the inspection.(3) the installation position of the valve shall be in the direction of easy inspection during the test.(4) welding connection valve, not with blind plate pressure test can be used when the cone seal or O ring seal pressure test.(5) when hydraulic test, the valve air will be excluded as much as possible.(6) the pressure should be increased gradually during the test, and the pressure will not be sudden and sudden.(7) strength test and sealed test duration is generally 2~3min, important and special valves should last 5min. Small caliber valve test time can be a little shorter, large caliber valve test time can be longer. During the test, the test time can be extended if in doubt. Strength test, does not allow the body and bonnet sweating or leakage. Sealing test, the general rotor valve only once, the safety valve, high pressure valve and other raw valve to be carried out two times. When testing for the low pressure, large diameter valve is not important and there are provisions to allow leakage of the valve, allowing a small amount of leakage; the common valve, power station valve, marine valves and other valve requirements vary on leakage requirements according to relevant regulations.
