If my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your like, your work is very important to me, and your support is also the dynamic and vertical momentum of my progress. Finally, I wish you good health and a good mood!

J41W-16 is a stainless steel flange globe valve, which is suitable for nitric acid, acetic acid and other occasions in chemical and other industries. The nominal diameter is 125 (mm), the nominal pressure, the working temperature is -29 550.

1. Globe valve, also known as cut-off door, is the most widely used valve, it is widely popular because of the small friction between the sealing surfaces in the opening and closing process, relatively durable, the opening height is not large, easy to manufacture, easy to maintain, not only suitable for medium and low pressure, but also suitable for high pressure. The closing principle of the globe valve is to rely on the pressure of the valve stem to make the sealing surface of the disc and the sealing surface of the valve seat fit tightly to prevent the flow of medium.

2. The valve plays an important role in cutting off and throttling the medium in the pipeline where it is located, and the globe valve is an extremely important cut-off valve, and its sealing is by applying torque to the valve stem, and the valve stem exerts pressure to the valve disc in the axial direction, so that the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted, and the medium is prevented from leaking along the gap between the sealing surfaces.

Summary. The difference is only that the sealing surface material is different.

The globe valve, also known as the shut-off valve, is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve from the bottom of the valve disc, the resistance that needs to be overcome by the operating force is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium, and the force of closing the valve is greater than the force of opening the valve, so the diameter of the valve stem should be larger, otherwise the failure of the top bend of the valve stem will occur. According to the connection method, it is divided into three types:

Flange connection, thread connection, welded connection. After the appearance of the self-sealing valve, the medium flow direction of the globe valve is changed from the top of the disc to enter the valve cavity, at this time, under the action of medium pressure, the force of closing the valve is small, and the force of opening the valve is large, and the diameter of the valve stem can be reduced accordingly. At the same time, under the action of the medium, this form of valve is also tighter.

China's valve "three to give" has stipulated that the flow direction of the globe valve is all top-down. When the globe valve is opened, the opening height of the disc is 25% to 30% of the nominal diameter. The maximum flow rate has been reached, indicating that the valve has reached the fully open position.

Therefore, the fully open position of the globe valve should be determined by the stroke of the disc.

What is the difference between the globe valve J41W-16 and J41H-16.

Hello. Good.

Indicates the flange connection j indicates the globe valve, and the nominal pressure is 16 kg. 1 indicates the DC channel, and the disc is unbalanced. W means that the sealing surface of the valve seat is trembling by the valve body material and directly added to the spring calendar. h represents alloy steel density surface, and 16 represents pn1

Can both be used on steam?

The difference is only that the sealing surface material is different. The globe valve, also known as the shut-off valve, is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to ensure that the sealing surface does not leak. When the medium enters the valve from the bottom of the valve disc, the resistance of the bright pie that needs to be overcome by the operating force is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium, and the force of closing the valve is greater than the force of opening the valve, so the diameter of the valve stem should be larger, otherwise the failure of the top bend of the valve stem will occur.

According to the connection method, it is divided into three types: flange connection, thread connection, and welded connection. After the appearance of the self-sealing valve, the medium flow direction of the globe valve is changed from the top of the disc into the valve cavity, at this time, under the action of medium pressure, the force of closing the valve is small, and the force of opening the valve is large, and the diameter of the valve stem can be reduced accordingly.

At the same time, under the action of the medium, this form of valve is also tighter. China's valve "three to give" has stipulated that the flow direction of the globe valve is all top-down. When the globe valve is opened, the opening height of the disc is 25% to 30% of the nominal diameter.

The maximum flow rate has been reached, indicating that the valve has reached the fully open position. Therefore, the fully open position of the globe valve should be determined by the stroke of the disc.

The difference between the two is only the difference in the material of the sealing surface, that is: the sealing surface material of J41W-16 is the same material as the valve body, and the sealing surface material of J41H-16 is stainless steel.

The opening and closing parts of the globe valve are plug-shaped discs, and the sealing is flat or sea cone, and the disc moves in a straight line along the center line of the valve seat.

The valve stem is in the form of a short movement (common name: dark rod), and there is also a lifting and rotating rod type that can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

According to the model of the file beam, it can be seen that the positive limb of the J41W globe valve is a flange globe valve made of stainless steel and sealed by the body seal. The appearance is as follows:

The stem axis of the J41W globe valve is perpendicular to the sealing surface of the valve seat. The slag opening or closing stroke of the valve stem is relatively short, and has a very reliable shut-off action, which makes this kind of valve very suitable for the use of cut-off or adjustment and throttling of the medium.

Dear, hello, I am glad to answer for you: the length of the flange connection of the globe valve J43H-16C? A:

The length is a flanged globe valve, in fact, it is a globe valve with flange connection as the connection method, and its working principle is the working principle of the globe valve - to apply torque to the valve stem, so that the valve stem exerts pressure on the valve disc in the shaft direction, so that the sealing surface of the valve plate and the valve seat are tightly fitted, so as to prevent the medium from leaking from the gap. Advantages: 1. The flanged globe valve is a forced sealing valve, which has good sealing, small friction between sealing surfaces and long service life.

2. The flanged globe valve is composed of several parts: valve body bonnet, valve stem, valve disc, valve stem nut, packing, gasket and hand wheel, which are relatively convenient for manufacturing and maintenance. 3. When the opening height of the valve disc reaches 25%-30% of the nominal diameter, the flow rate reaches the maximum value, indicating that the valve is in a fully open state, and the disc stroke of the flanged globe valve is small, and its working stroke is also small, and the time required for opening and closing is short.
