型号为Q61Y-800LB，公称口径是DN6-DN80采用金属对金属的密封副即金属密封球阀，球体表面采用先进的喷涂技术，通过对各种不同工况条件的处理，硬度可达HRC78。 Q61Y high temperature and high pressure hard seal ball valve model Q61Y-800LB, nominal diameter is DN6-DN80 metal-to-metal sealing pair, metal sealing ball valve, the surface of the ball uses advanced spraying technology, through the treatment of various working conditions, hardness Up to HRC78. HRC72。 The treatment of valve seat sealing surface can reach HRC72. The ball and seat are ground in pairs. All sealing areas on the entire sealing surface of the ball valve are precision ground. Q61Y high temperature and high pressure hard seal ball valve In order to ensure reliable sealing at various temperatures and pressures, according to different operating conditions and requirements of users, a variety of advanced ball and valve seat hardening technologies can be used, including supersonic spraying, nickel-based Spray welding, special surface hardening, hard alloy spray welding, and use of high-strength and high-hardness ceramic materials, etc. The surface hardness of the ball and valve seat can generally reach HRC60 or higher, and can reach HRC74 or higher. The temperature of the sealing surface material can reach 540 ℃ and 980 ℃. The bonding strength of the material can reach more than 10,000 PSI, and the sealing surface material also has good abrasion resistance, impact resistance and other properties, which can be suitable for most severe working conditions.

Q61Y高温高压硬密封球阀产品特征： Product features of Q61Y high temperature and high pressure hard seal ball valve:
金属对金属阀座密封 1.Metal-to-metal valve seat seal
双切断和排放 2.Double cut-off and discharge
双活塞作用阀座 3.Double piston action valve seat
带有石墨垫圈的安全防火设计 4.Safety and fireproof design with graphite gasket
阀座选用圆柱形绷簧加截的金属硬密封布局，能适应于较高温度及各种粉尘与固体颗粒介质 5. The valve seat adopts a metal hard seal layout with a cylindrical stretch spring and a cut, which can be adapted to higher temperatures and various dust and solid particulate media.
选用下装式阀杆、设置倒密封布局，保证填料处牢靠密封及避免阀杆脱出 6. Select the bottom-loading stem and set the inverted seal layout to ensure that the packing is firmly sealed and to prevent the stem from coming out.
自身具有防火防静电功用 7, own fire and anti-static function
手柄与阀杆选用扁方型衔接。 8. The handle and valve stem are connected by a flat square. Can also be added to lock the layout according to requirements to avoid misuse
该布局球阀应按规则流向运用。 9, the layout of the ball valve should be used in accordance with the rules of flow.
Q61Y高温高压硬密封球阀优点： Three, Q61Y high temperature and high pressure hard seal ball valve advantages:
1. Adopt metal seal to realize hard seal of metal spherical ring, fireproof and explosion-proof.
2. It adopts the form of metal seal, which has the characteristics of wear resistance, high temperature resistance and long service life.
3. The valve core of the sealing pair has a compensation amount, which can achieve reliable sealing and prolong service life.
4. The seal is tight, and the seal between the valve core and the valve seat is a spherical line contact. The top-loading eccentricity achieves zero leakage.
5. The compression sleeve can be unscrewed, the valve seat can be adjusted or replaced, and the valve can still be used, avoiding the disadvantages of the entire unit being scrapped after the failure of many existing valve seals.
