The disk of a gate valve is also known as a wedge. Bản quyền thuộc về thegioivalve.vn - Phát triển bởi IWISU hiện là đơn vị phân phối độc quyền của sản phẩm Van ANIX USA tại Việt Nam. To learn about each of these parts read complete guide of valve parts.Solid wedge is the most common & widely used disk type because of its simplicity and strength. In case, one-half of the disk is out of alignment; the disk is free to adjust itself to the seating surface. – VAN CẦU GANG JS1049 PN16. gate valves either stops or allows flow through the valve and acts somewhat like the opening or closing of a gate and is called, appropriately, the gate valve. The photo shows the valve used for TB inlet valve. – VAN CẦU GANG JS1049 PN25 – VAN CẦU THÉP GS-C25 PN16.

Therefore virtually no resistance to flow. This means when a line is get heated by fluid and expand it does not create thermal blinding.For a rising stem valve, the stem will go up while opening the valve and move down when you close the valve. This type of valve is also known as OS & Y valve. The high velocity of the flow in the partially open valve may cause erosion of the disc and seating surfaces and also creates vibration and noise.Here you can see the main parts of the gate valve. The gate is also shown as a wedge, due to the shape is resembles. A cast-in recess or deeper and wider cut on wedge perimeter gives more flexibility but compromises the strength.This design improves seat alignment and offers better leak tightness. When the valve is open, the closure member is fully drawn up into the valve, leaving a complete opening for the flow stream. Thank You for subscribing to Hardhat Engineer. Tilting Check Valve.
The split wedge is suitable for handling noncondensing gasses and liquids at normal and high temperatures.Freedom of movement of the disk prevents thermal binding even though the valve may have been closed when a line is cold. It can be used in turbulent flow also.However, it does not compensate for changes in seat alignment due to pipe loads or thermal expansion. – VAN CẦU THÉP GS-C25 PN25Công ty IWISU là nhà nhập khẩu và phân phối các sản phẩm Van vi sinh của Osaka Nhật Bản. You can see the image. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. The high velocity of the flow in the partially open valve may cause erosion of the disc and seating surfaces and also creates vibration and noise. You can see in the image. The disc travels along the stem like a nut when the stem is rotated. Các dòng sản phẩm của VMV rất đa dạng và phong phú, đặc biệt là các sản phẩm GANG, THÉP…. TOA VALVE HOLDING INC.(holding company) has consolidated associated company TOA VALEVE ENGINEERING INC. by Absorption-type Merger and change the trade name to TOA VALVE ENGINEERING INC. Jul.2010 The technical license agreements for manufacturing of Forged Globe Valves for high pressure and high temperature service and Quick Closing Non-return Valve with HE Harbin Power Plant Valve …
This is a wedge gate valve that body is made of 9% Cr steel, with forged welding structure suitable for high pressure and high temperature of Ultra Super Critical (USC) pressure boiler plant. In inside screw design, the threaded portion of the stem is in contact with the flow medium, and when you open the valve, handwheel rise with the stem.Whereas in the case of outside screw design, the only smooth portion is exposed to the flow medium and the stem will rise above the handwheel. You can see the same in images.
