Description

Technical Field

[0001] The utility model relates to the technical field of flap valves, in particular to a novel hydraulic three-way flap valve. Background Art

[0002] The three-way flap valve in the ore conveying system is a large and heavy device, which plays a vital role in the entire conveying process. However, such a core component has relied on electric push rods as its power device for a long time in the past. Although electric push rods meet basic operating requirements to a certain extent, many of their problems cannot be ignored. The most prominent problem is that the overload protection function of the electric push rod is not satisfactory. In a heavy load environment such as ore transportation, the equipment often faces the challenge of overload, and the electric push rod is often difficult to protect itself in a timely and effective manner when facing these emergencies, thereby increasing the risk of equipment damage.

[0003] In addition, the performance of electric push rods in starting under load is also unsatisfactory. Since the ore conveying system usually needs to operate continuously and stably, the power device of the flap valve must have good starting performance. However, the shortcomings of electric push rods in this regard not only affect the overall efficiency of the system, but also increase the uncertainty and risk during operation. What is more serious is that the motor failure rate of electric push rods remains high. Frequent failures not only increase maintenance costs and time, but more seriously, it often causes the entire conveying system to be paralyzed. In this case, the operator has to take emergency measures to manually flip the flap, which is not only inefficient but also poses a safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0019] like Figure 1-Figure 3 As shown, a new type of hydraulic three-way flap valve includes a valve body 1, a flap 4 is rotatably connected inside the valve body, and a hydraulic push rod 2 is rotatably connected outside the valve body. Considering the stability of later use, the power device uses a hydraulic push rod. The advantages of the hydraulic push rod are that it can be started with load, has overload protection capability, is suitable for harsh environments, and has a long service life. Incidentally, the pushing force point of the flap is changed from the original line pushing the surface to the current surface pushing the line. The valve body is provided with a window for accommodating the insertion of the hydraulic push rod, and the telescopic rod of the hydraulic push rod passes through the window and is rotatably connected to the flap. After the modification, the three-way flap valve is simpler and more convenient to use, and more stable and reliable in operation. It solves the problem that the electric push rod cannot be pushed through when there is a little material on the flap, requiring manual assistance, and the problem that the liner of a single-layer flap cannot be replaced.

[0020] The solution is detailed. The flap is a double-layer design, which is easy to replace the lining and always ensures the integrity of the equipment. The material used is galvanized steel plate. The flap size is 1.8M*1.6M and the thickness is 8CM. 8+12 lining plates are installed on the outer surface of the flap. The bolts are buried and welded to replace them, and the flow direction can be adjusted.

[0021] Furthermore, the flap is provided with a hinge seat 41 which cooperates with the telescopic rod.

[0022] Furthermore, the inner wall of the valve body is provided with an oblique matching mounting seat 3, and the oblique matching mounting seat is provided with a placement matching groove 31 matching with the end of the flap. This matching method can ensure that the flap is embedded in the oblique matching mounting seat after the rotation is completed, avoiding the occurrence of jamming and deviation.

[0023] In at least one embodiment, the valve body includes a front side plate 13 and a rear side plate 18, a left side plate 11 and a right side plate 12 are provided on both sides of the front side plate and the rear side plate, a middle partition plate 14 is installed between the front side plate and the rear side plate, a rotating shaft 15 is provided on the middle partition plate, and a flap is rotatably connected to the rotating shaft. This structural layout is reasonable, so that the internal space of the valve body is fully utilized, and it is easy to install and maintain.

[0024] Furthermore, a support bracket 16 is provided outside the valve body, a fixed shaft 17 is installed on the support bracket, and a hydraulic push rod is rotatably connected to the fixed shaft. The arrangement of the support bracket and the fixed shaft makes the installation of the hydraulic push rod more firm and stable.

[0025] Furthermore, an observation window 111 is provided on the left side plate, which is convenient for the operator to observe the internal conditions of the valve body and the working status of the flap, and timely discover and deal with problems, thereby ensuring the normal operation of the equipment and production safety.

[0026] The scheme is detailed as follows: the left side panel is provided with a hinge 112, an observation window is installed on the hinge, a plug slot 114 is provided on the observation window, and a latch 113 is rotatably connected to the left side panel, and the latch can be rotated and inserted into the plug slot to limit the observation window from rotating around the hinge. This structure makes the opening and closing of the observation window more convenient and flexible, and the cooperation between the latch and the plug slot can ensure the sealing and stability of the observation window in the closed state.

[0027] Working mode, observe the situation inside the valve body through the observation window to confirm the position and state of the flap 4. When the flow direction of the fluid needs to be changed, start the hydraulic push rod 2 so that its telescopic rod pushes the flap 4 to rotate on the rotating shaft 15. Since the hydraulic push rod has overload protection capability, even if the flap is subject to greater resistance, it can smoothly push the flap to rotate. When the flap rotates to a predetermined position, stop the action of the hydraulic push rod 2, and the fluid will pass through the valve body in the new flow direction. If the liner on the flap needs to be replaced, the flap can be rotated to a position that is convenient for operation, and then the bolts on the liner are loosened, and a new liner is replaced and the bolts are re-fastened. Since the flap adopts a double-layer design, the entire flap does not need to be disassembled when replacing the liner, which greatly simplifies the maintenance process. During use, the situation inside the valve body can be regularly checked through the observation window 111 to ensure the normal operation of the flap and the hydraulic push rod. If an abnormal situation is found, it can be dealt with in a timely manner.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model.
