Product Description

Product Overview

The gate valve is also called manual knife gate valve. The knife gate valve is a valve whose gate plate and valve seat are always in close contact and sealed. Its principle is that the gate plate is provided with a circular opening with a diameter, and the opening and closing of the gate plate make the circular opening on the gate plate completely separate from and coincide with the diameter. The advantage of this valve is that the valve body diameter has no groove, the medium will not jam, and it has the flow characteristics of full diameter. Its sealing structure can be divided into soft sealing and hard sealing structures. The penetrating knife gate valve is characterized by precise structure, good processability, compact structure, etc. The sealing valve seat is designed as a movable structure, with wear prevention and automatic compensation functions, so its service life is longer. During the closing and opening process, the valve seat moves closely with the gate, which makes the opening and closing force of the valve stable and has the characteristics of cutting off the medium.

Working performance

Knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small volume, smooth passage, small flow resistance, light weight, easy installation, easy disassembly, etc. It can work normally under working pressure of 1.0MPa-2.5MPa and operating temperature of - 29-650 ºC.

The gate plate of the knife gate valve has the shearing function, which can scrape the adhesive on the sealing surface and automatically remove the debris. The stainless steel gate plate can prevent the seal leakage caused by corrosion.

Installation

Installation and use of knife gate valve
1. Before installation, check the valve chamber, sealing surface and other parts, and no dirt or sand particles are allowed to attach;
2. The bolts of all connecting parts 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 pay attention to the medium flow direction to ensure the consistency with the valve requirements;
5. When installing valves, users must reserve the necessary space for valve actuation;
6. The wiring of the drive device must be carried out according to the circuit diagram;
7. The knife gate valve must be maintained regularly and shall not be collided or squeezed at will to avoid affecting the sealing.
