Description

Technical Field

[0001] The utility model relates to the technical field of cement production and manufacturing, and in particular to a three-way flap valve. Background Art

[0002] The three-way flap valve is a control valve widely used in industrial production. It is mainly composed of a valve body, a valve cover, a flap, and a sealing gasket. It has one inlet and two outlets. The flow of fluid or gas can be controlled by adjusting the position of the flap, or it can be used for bypass diversion.

[0003] In the current cement production, the clinker production process requires a material chute for transportation. There are main routes and bypass routes during the transportation process. At this time, a three-way flap valve is needed for diversion. The material is discharged through the existing three-way pneumatic or electric flap valve. The clinker sintered in the clinker production is of different sizes, with a particle size between 1-200mm. In terms of quality control, when sampling the clinker, particularly large materials are not required. At this time, the three-way flap valve is required to have a screening function, and preliminary screening is required at the source to remove materials with a particle size greater than 30mm.

[0004] After searching, the applicant found that a Chinese patent document with publication number CN109073102A disclosed a three-way valve for flow control on December 21, 2018, comprising: a valve body, the valve body having a valve seat formed by a cylindrical cavity, the valve seat forming a first valve port with a rectangular cross-section for a first fluid to flow in, and a second valve port with a rectangular cross-section for a second fluid to flow in; a valve core, the valve core is rotatably arranged in the valve seat of the valve body in such a manner that the first valve port is switched from a closed state to an open state while the second valve port is switched from an open state to a closed state, and is formed into a semi-cylindrical shape with a predetermined central angle and the two end faces along the circumferential direction are formed into a curved surface shape; and a driving member, the driving member rotationally drives the valve core; this device also cannot solve the above-mentioned problem.

[0005] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the existing three-way valve structure. Utility Model Content

[0020] The beneficial effects of this application are:

[0021] 1.

[0023] 3. When the material flows in the valve body, it completely relies on gravity. When the screen flap does not move, large particles are blocked on the screen flap during material discharge, causing the valve body to be blocked. Therefore, this device is equipped with a pneumatic vibrator near the screen flap shaft to help material screening and discharge. BRIEF DESCRIPTION OF THE DRAWINGS
