Since the emergence of self-sealing valves, the medium flow direction of the stainless Globe Check valve has changed from above the disc to enter the valve chamber. At this time, under the action of medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be adjusted accordingly reduced. At the same time, under the action of the medium, this form of stopcock is also tighter. In addition, the inflow direction of Globe Valve is generally top-down. When the Globe Valve is opened, the opening height of the slice is 25 to 30 of the nominal periphery. The inflow has reached the outside, indicating that the stopcock has reached the completely open position. Thus, the completely open position of the Globe Valve should be determined by the stroke of the stopcock slice. Next, let's take a look at the applicable knowledge of Globe Valve.
Here is the content list:
What is Globe Valve?
Globe Valve working principle and characteristics.
What are the factors that affect the price of Globe Valve?
Globe Check Valve, also called a cut-off stopcock, is one of the most extensively used faucets. The reason why it's popular is that the disunion between the sealing shells is small during the opening and ending process. It's fairly durable, the opening height isn't large, it's easy to manufacture, and it's accessible to maintain. Globe Valve isn't only suitable for medium and low pressure, but also high pressure. Its ending principle is to calculate the pressure of the stopcock rod to make the sealing face of the slice and the sealing face of the stopcock seat fit nearly to help the inflow of the medium.
The stopcock plays an important part in cutting off and strangling the medium in the channel where it's located. As an extremely important cut-off valve, Globe Valve is sealed by applying torque to the valve stem, and the valve stem exerts pressure on the valve disc in the axial direction, so that the sealing surface of the valve disc and the sealing surface of the valve seat fit closely, preventing the medium leaks along the gap between the sealing surfaces. The valves pair of cut-off valves are composed of a disc-sealing surface and seat sealing surface, and the valve stem drives the disc to move vertically along the center line of the valve seat. The opening height of the Globe Valve is small during the opening and closing process, which is easy to adjust the flow rate, is convenient to manufacture and maintain and has a wide range of pressure applications. Globe Valve is compared with another commonly used cut-off valve in industrial production the gate valve. Structurally speaking, Globe Valve is simpler than the former and is easy to manufacture and maintain. In terms of service life, the sealing surface of Globe Valve is not easy to wear and scratch, and there is no relative sliding between the valve disc and the sealing surface of the base during the valve opening and closing process, so the wear and scratch of the sealing surface are small, so the sealing pair is improved service life. Globe Valve has a small disc stroke during the fully closed process, and its height is smaller than that of gate valves.
In the process of purchasing stop valve products, we will find that the selling price of the products will be different. Each manufacturer's price is different. In the process of purchasing a product, what factors are related to the sales price of the product? This has become a question that some users want to know about. When purchasing, Globe Valve's sales price is directly related to the product brand. Many Globe Valves have their brands, each with its technology and reputation. In the process of purchasing products, even if the same brand is selected, the sales price of the product will vary depending on the product model. When purchasing a product, users should not only choose the right brand but also choose the right model according to the needs of users, so that the product will have a better use effect when used. Different brands of products use different raw materials and different production and processing techniques in the production and processing process, resulting in different production and processing costs. Therefore, you will find that in the process of purchasing products, when products of different brands are promoted in the market, due to the difference in production costs, the sales prices of the products will also be different.
