Description

Technical Field

[0001] The utility model relates to the field of gate valves, in particular to an anti-siltation gate valve. Background Art

[0002] A gate valve is a disc-type opening and closing mechanism. The disc's movement is perpendicular to the flow direction, allowing it to only fully open and fully close; it cannot be adjusted or throttled. A gate valve seals through contact between the valve seat and the disc. The sealing surface is typically welded with metal materials, such as 1Cr13, STL6, or stainless steel, to increase wear resistance. Gate discs can be rigid or flexible. However, existing anti-siltation gate valves still struggle to effectively separate sludge from wastewater, preventing the separated sludge from being quickly discharged.

[0003] For example, the utility model disclosed in the publication (announcement) number CN217328528U discloses a new type of gate valve that prevents siltation and leakage, including a gate valve seat, a mounting valve cover, a support rod, a valve stem, a handwheel, a connecting flange, an outlet, a conduit, a sedimentation box, an inlet and a silt discharge system, wherein: the mounting valve cover is mounted on the top of the gate valve seat by bolts, and the support rod is mounted on the surface of the mounting valve cover by bolts, the valve stem is embedded in the gate valve seat, the mounting valve cover and the inside of the support rod; the handwheel is mounted on the top of the valve stem by bolts, and the connecting flanges are welded on both sides of the gate valve seat, the outlet is mounted on one end of the connecting flange by bolts; the conduit is mounted on one end of the connecting flange by bolts, and the sedimentation box is mounted on the other end of the conduit by bolts, and the inlet is welded to the surface of the sedimentation box.

[0004] The device of the above-mentioned utility model is provided with a sedimentation box for separating sewage, but the gate valve does not separate the sludge in the sewage through the sedimentation box thoroughly enough, so that some sludge still flows into the valve seat of the gate valve along with the sewage, making it easy for silt impurities to accumulate in the sealing groove provided at the bottom of the gate valve, thereby causing poor sealing of the gate valve and inconvenience in cleaning. At the same time, the sedimentation box only separates the sludge by sedimentation, so that the sludge separation effect needs to be enhanced. Utility Model Content

[0005] The purpose of the present utility model is to provide an anti-siltation gate valve to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-siltation gate valve, comprising a processing box, one end of which is connected to one end of the gate valve body through a pipeline and a flange, and a first partition is fixedly connected to the inside of the processing box, and a plurality of third partitions and fourth partitions are respectively arranged in parallel on one side close to the first partition and the second partition.

[0007] Preferably, a sewage inlet is provided on a side of the treatment box away from the gate valve body.

[0008] Preferably, a cover plate is fixedly mounted on the top of the processing box by a plurality of bolts.

[0009] Preferably, the first partition plate, the second partition plate, the third partition plate and the fourth partition plate are fixedly connected to both sides of the inner wall of the processing box respectively.

[0010] Preferably, a sewage outlet is fixedly installed at the bottom end of the processing box.

[0011] Preferably, several third partitions are arranged in parallel along one side of the first partition, and several fourth partitions are arranged in parallel with the second partition close to the first partition, and each fourth partition is distributed in the middle of two adjacent third partitions.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model is provided with a first partition and a second partition symmetrically about the center position of the treatment box inside the treatment box, so as to preliminarily intercept the sewage entering the treatment box from the sewage inlet, thereby promoting the sludge sedimentation of the sewage and separating it from the water. The distance and time for the sewage to flow inside the treatment box are increased by the multiple third partitions and the fourth partitions arranged in parallel. The sewage can fully contact the inner walls of the third partition and the fourth partition after passing through the multiple third partitions and the fourth partition to intercept the sludge, thereby ensuring that the sludge of the sewage can have sufficient time to undergo the sedimentation and separation process, avoiding siltation of the gate valve body affecting its use.

The distance and time for the sewage to flow inside the treatment box 1 are increased by the parallel arrangement of multiple third partition plates 4 and fourth partition plates 5. The sewage can fully contact the inner walls of the third partition plates 4 and the fourth partition plates 5 after passing through the multiple third partition plates 4 and the fourth partition plates 5 to intercept the sludge, thereby ensuring that the sludge of the sewage can have sufficient time to undergo the sedimentation and separation process, avoiding siltation of the gate valve body 7 and affecting its use.
