What is the function of the diversion hole of the stainless steel plate gate valve with diversion?
Stainless steel slab gate valve with diversion is a sliding valve whose closing parts are parallel gates. The closing part can be a single ram or a double ram with a stretching mechanism in between. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat. If it is a double gate valve, the expansion mechanism between the two gates can supplement this pressing force. It is a sliding valve whose closure is a parallel gate.

If it is a double gate valve, the expansion mechanism between the two gates can supplement this pressing force.
Installed on the pipeline, it can also be directly pigged with a pig. Since the gate slides on the two seat surfaces, it is also applicable to the medium with suspended particles, and the sealing surface is actually positioned automatically. The sealing surface of the valve seat will not be damaged by thermal deformation of the valve body. And even if it is closed in a cold state, the thermal elongation of the valve stem will not overload the sealing surface. At the same time, when the gate valve is closed, the flat gate valve without diversion holes does not require high precision in the closing position of the gate plate, so the stroke can be used to control the opening and closing position.
This series of valves has the characteristics of reliable sealing performance, small opening and closing torque, sulfur resistance and wear resistance, long service life, and can be used to clean pipelines through wool balls. It is suitable for opening and closing devices in pipeline systems with non-corrosive and corrosive media such as water, oil, natural gas, and steam, especially for fields such as stone, oil, gas, and long-distance pipelines.
Its design feature is that several springs are set on the arc-shaped bottom to ensure that the gate retreats downward when it is closed, and automatically rises when it is opened, so that the groove becomes a "flat bottom" to prevent garbage accumulation and prevent the gate from being unable to open and close normally. The stainless steel slab gate valve with diversion not only solves the selection problem of the riverside sewage treatment plant project, but also is the new darling of the water supply and drainage valve industry.
What is the main function of the diversion hole?
In fact, if it needs to be further subdivided, the slab gate valve can also be further classified into a small classification, that is, the gate valve with an adjustable gate, which has a semicircular hole under the gate, which can be understood as a half diversion hole, so I won’t go into details here.
From a structural point of view, the diversion hole is actually a small circular hole on the gate. For this circular small hole, the obvious difference between the gate valve with the diversion hole and the gate valve without the diversion hole is that the gate valve with the diversion hole is not completely closed in the traditional sense, and the medium can always pass through. However, due to the limited diameter of the diversion hole, some larger substances cannot successfully pass through the gate valve. This step is actually very beneficial to the cleaning of the stainless steel flat gate valve with diversion and the interception of impurities.
