製品導入:
The valves disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation. Non-rising resilient seated gate valves solve the problem in general gate valves such as leakage, rusting etc. and saves installation space. It is used widely in tap water industry, sewage treatment, shipping construction, petroleum, chemicals, food, pharmacy, textile, electric power, metallurgy and energy system's pipeline to adjust and shut off fluids.
We are able to supply an array of Gate Valves covering Universal Gate Valves of Cast Iron Gate Valve, Ductile Iron Gate Valve, Cast Steel Gate Valve and Forged Steel Gate Valve, Cryogenic Gate Valves, Bellow Sealed Gate Valves and Sliding Gate Valves etc.
Gate valves are utilized whenever a straight-line flow of fluid and minimum restriction is preferred. Gate valves are extremely named since the part that either stops or enables flow with the valve functions somewhat such as the opening or closing of the gate and it is known as, appropriately, the gate. The gate is generally wedge formed. Once the valve is available, the gate is fully attracted up in to the valve, departing a dent for flow with the valve exactly the same size because the pipe where the valve is installed. Therefore, there's little pressure drop or flow restriction with the valve. Gate valves aren't appropriate for throttling purposes because the charge of flow could be difficult because of valve design because the flow of fluid slapping against a partly open gate may cause extensive harm to the valve. Except as particularly approved, gate valves shouldn't be employed for throttling.
Gate valves are called either RISING STEM or NONRISING STEM valves. Around the nonrising-stem gate valve, the stem is threaded around the lower finish in to the gate. Because the handwheel around the stem is rotated, the gate travels up or lower the stem around the threads, as the stem remains vertically stationary. This kind of valve more often than not includes a pointer-type indicator threaded to the upper finish from the stem to point valve position.
The increasing-stem gate valve has got the stem connected to the gate the gate and stem rise minimizing together because the valve is operated.
Gate valves utilized in steam systems have flexible gates. The reason behind utilizing a flexible gate would be to prevent binding from the gate inside the valve once the valve is incorporated in the closed position. When steam line is heated, they'll expand, causing some distortion of valve physiques. If your solid gate fits snugly between your seat of the valve inside a cold steam system, once the product is heated and pipes elongate, the seats will compress from the gate, wedging the gate together and clamping the valve shut. This issue is overcome by utilization of an adaptable gate (two circular plates mounted on one another having a flexible hub in the centre). This design enables the gate to flex because the valve seat compresses it, therefore stopping clamping.
特徴:
1. The seal is designed with dust proof ring plus three "O"-seal ring, reliable sealing, on-line replaceable.
2.ゲートとアルミニウム青銅ベアリングの両方が援助デザインの良い自己潤滑性、高強度でであり、アルミニウム青銅は、長い時間の使用後、一体的にゲートを交換する必要なく交換ベアリング持つことができます。
3.ゴムは、ゲート抗腐食、良い気密性を包みました。
非毒性エポキシ樹脂で被覆された4.高度な表面処理は、静的粉末、抗腐食、無公害、使用することができる飲料水パイプラインを辞任します。
5.本体がゲートスロットなしで設計され、スムーズな通路は不純物が下水労働条件のために、より多くの適用いっぱいに取得することはできません。
6.一体型シールは、信頼性の高い動作します。 ゼロ漏れunder1.5時間公称圧力を出て、低圧いずれかの、0.02Mpa下、高圧シール用。
