Description

Technical Field

[0001] The utility model relates to the technical field of industrial tower trays, in particular to an anti-clogging self-cleaning float valve. Background Art

[0002] The float valve can float on the tower plate and change its opening degree with the change of gas flow. There are many types of float valves, including round valves and strip-shaped angle valves. China mainly uses round valves, among which the most commonly used is the F1 type. There are ministerial standards issued in China, which stipulate that the valve body material can be made of carbon steel, stainless steel or acid-resistant steel; the light valve is 1.5mm thick and weighs about 25g, and the heavy valve is 2mm thick and weighs about 33g.

[0003] According to a floating valve tray disclosed in Chinese patent number CN 205379782 U, it includes a tray and a floating valve, the tray is provided with a mounting hole for the floating valve, the floating valve includes a valve cover and valve legs arranged at both ends of the valve cover and perpendicular to the valve cover, the leg plates of the valve legs are provided with side holes, the inner side walls of the side holes are overlapped with separation strips, the valve cover is provided with a plurality of upwardly arched convex caps, and the side walls of the convex caps are provided with a plurality of air holes extending axially and distributed in a circumferential direction. The floating valve tray can effectively disperse the airflow and promote full contact between gas and liquid.

[0004] The side wall of the tower plate float valve convex cap in the prior art is provided with a plurality of air holes extending axially and distributed in a circumferential direction, which can effectively disperse the liquid. However, when in use, the liquid outlet is easily blocked, and the existing float valve cannot be automatically cleaned, so it will affect the full contact between gas and liquid. Therefore, an anti-blocking self-cleaning float valve is needed to solve the above problem. Utility Model Content

[0005] The utility model aims to solve the problem that the liquid outlet in the prior art is easily blocked and the existing float valve cannot be automatically cleaned, thus affecting the full contact between gas and liquid, and proposes an anti-blocking self-cleaning float valve.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-clogging self-cleaning float valve, including a floating plate, the top annular array of the floating plate has valve ports, the outside of the top of the valve ports are clamped with embedded rings, the inside of the embedded rings are provided with cleaning bristles, and the inside of the valve ports is clamped with a bottom plate.

[0007] Preferably, a circular opening is formed at the bottom of the bottom connecting plate, a circular groove is formed at the top of the bottom connecting plate, and a cover is clamped at the top of the circular groove.

[0008] Preferably, the cover is in the shape of a truncated cone, an inner cavity is provided inside the cover, and an inner annular array of the inner cavity is provided with lifting grooves.

[0009] Preferably, a top limiting ring is installed at the top inside the cover, and a bottom limiting ring is installed at the bottom inside the cover.

[0010] Preferably, the cover is internally slidably connected to a lifting head, a welding ring is welded to the outside of the top end of the lifting head, a sliding block is arranged in an outer annular array of the welding ring, the sliding block and the lifting slot are adapted to each other, the middle part of the lifting head is hollow, and a mounting ring is opened on the top of the lifting head.

[0011] Preferably, a liquid outlet sleeve is clamped on the top of the mounting ring, and the outer annular array of the liquid outlet sleeve has liquid outlet holes.

[0012] Preferably, a top plate cover is installed on the top of the liquid outlet sleeve, and a bottom opening is opened at the bottom of the liquid outlet sleeve.

[0013] Beneficial Effects

[0014] In the utility model, the entire valve core structure is mainly composed of a bottom receiving plate, a cover, a lifting head, a liquid outlet sleeve and a top plate cover. The liquid in the tower will enter from the circular opening at the bottom of the bottom receiving plate and then enter the cover. When the liquid enters the cover, it will push the lifting head in the cover upward. The lifting range of the lifting head is limited to the inner cavity. The top limit ring and the bottom limit ring in the cover are used for limiting.

[0015] In the utility model, the lifting head slides in the inner cavity through the slider outside the welding ring. When the lifting head rises, it will drive the liquid outlet sleeve on the top to move upward. When the liquid outlet sleeve moves upward, the top plate cover will be lifted up, and the liquid outlet sleeve will be exposed. At the same time, the liquid surging at the bottom will enter the liquid outlet sleeve and overflow from the external liquid outlet hole. When the liquid outlet sleeve moves upward, it will pass through the embedded ring, and the cleaning bristles inside the embedded ring will directly contact the liquid outlet sleeve. The cleaning bristles will scrape off the blockage in the liquid outlet hole on the surface of the liquid outlet sleeve, so as to prevent clogging by impurities. This solves the problem that the liquid outlet is easily blocked in the prior art, and the existing float valve cannot be cleaned automatically, which will affect the full contact between gas and liquid.
