Technical Field

The invention belongs to the technical field of valves, and particularly relates to an anti-blocking gate valve suitable for discharging multi-impurity liquid.

Background

The gate valve is one of the most commonly used shut-off valves, and is mainly used for connecting or shutting off a medium in a pipeline and is not used for regulating the flow of the medium. The applied pressure, temperature and diameter range is large, especially applied to medium and large diameter pipelines. The gate valve has the following advantages: (1) the fluid resistance is small. The medium through holes in the gate body are straight-through, and the flowing direction of the medium is not changed when the medium flows through, so that the flowing resistance is low. (2) The opening and closing are labor-saving. The moving direction of the valve plate is vertical to the flowing direction of the medium when the valve plate is opened and closed. Compared with other valves, the valve is labor-saving to open and close. (3) The direction of the medium flow is generally not limited. The medium can flow through from any direction on both sides, and can achieve the purpose of connection or disconnection. The device is convenient to install and is applied to pipelines with the flow direction of the medium possibly changed.

In the prior art, for a liquid transport vehicle with more impurities, when liquid needs to be discharged, as the impurities in the liquid are too much and possibly too large and hard, a discharge port is easily blocked, and the liquid cannot be discharged efficiently; the other problem existing in the prior art is that the valve plate is vulcanized in the related valve seal at present, so that the maintenance cost is high after the seal is damaged, and the sealing effect is poor.

After adopting this preferred scheme, the knife type flashboard can not harm T type sealing washer through the guide effect of inclined plane or cambered surface at the reciprocating motion in-process, makes in close contact with between T type sealing washer and the knife type flashboard, improves sealed effect, prolongs T type sealing washer's life.

Preferably, one side of the mounting plate, which is far away from the knife-type gate plate, is provided with an O-shaped sealing ring.

After adopting this preferred scheme, O type sealing washer is static seal, can prevent that liquid from leaking from mounting panel one side, improves the sealed effect of valve.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

1. the knife-type gate plate makes the gate plate completely leave the discharge port under the action of the gate plate push rod, and the discharge port is not shielded; if the discharge port is blocked by large or hard impurities, the knife-shaped flashboard is moved back and forth, the impurities are cut off under the action of the knife edge, and the discharge port is dredged, so that the discharge is ensured to be smooth and reliable.

2. When the valve seal is invalid, only the T-shaped sealing ring needs to be replaced, the T-shaped seal can be replaced by detaching the T-shaped seal outer ring or the T-shaped seal inner ring, the operation is convenient and fast, and the maintenance cost is reduced.

3. The knife-type gate plate reciprocates under the guidance of the first V-shaped guide groove and the second V-shaped guide groove, so that the knife-type gate plate is ensured to be reliably contacted with the T-shaped sealing ring, and the sealing performance is improved.
