進口刀型閘閥產品優(yōu)勢-德國洛克

 

進口刀型閘閥結構特點:

刀型閘閥顧名思義就是平板閥板底部具有刀型斜切口，具有切斷介質的功能，使得閥門關閉不受介質阻塞。此閥門一般用于紙漿、煤灰、化工原料、污水、食品等介質的流通啟閉。壓力范圍一般都1.6MPa以內使用，溫度一般在120℃以下使用，高溫也可以用特殊材質代替使用。根據密封性能要求可以分軟密封和硬密封。軟密封可以達到0泄露，硬密封根據不同泄露等級檢驗。

該閥門操作方便,開啟自由,運動靈活可靠; 閥瓣裝配維修簡單, 密封結構合理, 密封圈更換方便實用。

進口刀型閘閥工作原理:

 刀閘閥關閉時,密封面可以只依靠介質壓力來密封,即依靠介質壓力將閘板的密封面壓向另一側的閥座來保證密封面的密封,這就是自密封.大部分閘閥是采用強制密封的,即閥門關閉時，要依靠外力強行將閘板壓向閥座,以保證密封面的密封性。

Working principle of imported knife gate valve:
When the knife gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, the medium pressure will press the sealing surface of the gate valve to the seat on the other side to ensure the sealing surface, which is self sealing. Most gate valves adopt forced sealing, that is, when the valve is closed, the gate valve should be pressed to the seat by external force to ensure the sealing surface tightness.
                                                                               

進口刀閘閥安裝須知:

1.安裝前須檢查閥門腔內和密封面等部位，不允許有污物或砂粒附著；

2.各連接部位螺栓,要求均勻擰緊；

3.檢查填料部位要求壓緊，既保證填料的密封性，也要保證閘板開啟靈活；

4.用戶在安裝閥門前，必須校對閥門型號，連接尺寸及注意介質流向，保證與閥門要求一致性；

5.用戶在安裝閥門時，必須預留閥門驅動的必要空間；

6.驅動裝置的接線須按線路圖進行；

7.刀型閘閥必須定期保養(yǎng)，不得隨意碰撞及擠壓，以免影響密封。

Instructions for installation of imported knife gate valve:
1. Check the valve cavity and sealing surface before installation, and no dirt or sand is allowed to adhere to them;
2. The bolts of each connecting part shall be tightened evenly;
3. Check the packing position to ensure the tightness of the packing and the flexible opening of the ram;
4. Before installing the valve, the user must check the valve model, connection size and medium flow direction to ensure the consistency with the valve requirements;
5. When installing the valve, the user must reserve the necessary space for valve driving;
6. The wiring of driving device shall be carried out according to the circuit diagram;
7. The knife gate valve must be maintained regularly. It is not allowed to collide and squeeze at will, so as not to affect the seal.
