Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, and in particular to a one-way valve for mineral slurry that facilitates rapid unblocking of blockages. Background Technology

[0002] Due to the high concentration and large amount of solid particles in the slurry, blockages easily occur in the valve seat when it passes through the check valve, preventing the valve core from resetting properly and causing backflow. Therefore, the top cover of the check valve needs to be frequently disassembled for cleaning, which is cumbersome, time-consuming, and impacts production efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a convenient, quick-maintenance, and efficient one-way valve for clearing blockages in slurry, thus ensuring production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model for a slurry check valve that facilitates rapid unblocking of blockages is as follows:

[0005] A one-way valve for slurry that facilitates rapid unblocking includes a valve seat with an inlet and an outlet. The valve seat contains a valve for sealing the inlet. The valve is slidably connected to the valve seat via a valve stem. A sludge-clearing pipe passes through the valve stem. A handle is provided at one end of the sludge-clearing pipe extending out of the valve seat. The handle has an inlet that communicates with the inner cavity of the sludge-clearing pipe. The end of the sludge-clearing pipe extending into the valve seat is a closed end. Several outlets are provided on the side wall of the sludge-clearing pipe adjacent to the closed end.

[0006] Preferably, the sludge removal pipe is slidably connected to the valve stem, and a set screw is provided on the side of the valve stem extending out of the valve seat. The outer wall of the sludge removal pipe is provided with a working positioning groove and a flushing positioning groove that cooperate with the set screw.

[0007] Preferably, the outer wall of the closed end of the sludge removal pipe is provided with a limiting boss that mates with the bottom surface of the valve stem.

[0008] Preferably, a sealing ring is provided between the limiting boss and the bottom surface of the valve stem.

[0009] Preferably, a reset verification line is provided on the outer wall of the valve stem, and when the valve seals the valve seat inlet, the reset verification line is flush with the top surface of the valve seat.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] When blockage occurs inside the valve seat, clean water is introduced through the cleaning pipe, and the valve stem is moved to flush the inside of the valve seat, especially the inlet. There is no need to remove the cover plate, making the operation convenient, shortening maintenance time, and thus ensuring production efficiency. Attached Figure Description

[0020] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0021] like Figure 1-7As shown, a one-way valve for slurry that facilitates rapid unblocking includes a valve seat 1 with an inlet 11 and an outlet 12. A valve 2 for sealing the inlet is installed inside the valve seat. The valve 2 is slidably connected to the valve seat via a valve stem 3. A sludge-removing pipe 4 passes through the valve stem. A handle 41 is installed at the end of the sludge-removing pipe extending out of the valve seat. The handle has an inlet 411 communicating with the inner cavity of the sludge-removing pipe. The end of the sludge-removing pipe extending into the valve seat is a closed end. Several outlets 42 are provided on the side wall of the sludge-removing pipe adjacent to the closed end. To prevent blockage at the outlets, the sludge-removing pipe is slidably connected to the valve stem. The seat is threaded with a set screw 31 on one side. The outer wall of the sludge pipe is provided with a working positioning groove 43 and a flushing positioning groove 44 that mate with the set screw. The outer wall of the closed end of the sludge pipe is provided with a limiting boss 45 that mates with the bottom surface of the valve stem. When the limiting boss is in contact with the bottom surface of the valve stem, the set screw can be inserted into the working positioning groove. When the bottom surface of the pull piece is in contact with the top surface of the valve stem, the set screw can be inserted into the flushing positioning groove. A sealing ring 32 is installed on the bottom surface of the valve stem to prevent slurry from entering the sludge pipe. A reset check line 33 is provided on the outer wall of the valve stem. When the valve seals the valve seat inlet, the reset check line is flush with the top surface of the valve seat.

[0022] The specific working process and principle of a slurry check valve for easy and rapid unblocking: Slurry enters the valve seat through the inlet. The valve, under pressure, compresses the valve stem and pushes the return spring 5 upwards, allowing the slurry to exit through the outlet. When the slurry flow stops, the valve stem, under the action of the return spring, moves the valve downwards, sealing the inlet. If there is blockage at the inlet, the valve cannot fully return to its original position, and the reset calibration line will not be flush with the top surface of the valve seat, requiring dredging. First, tighten the set screw. After the set screw is removed from the working positioning groove, the dredging pipe can be pushed downwards until the bottom surface of the pull piece touches the top surface of the valve stem. Tighten the set screw to insert it into the flushing positioning groove, open the manual shut-off valve connected to the inlet, and introduce clean water into the dredging pipe. The clean water sprays out from the outlet at the bottom of the dredging pipe. At this time, the outlet can be lifted by the pull piece to flush the valve seat outlet and its inner cavity until the valve stem moves downwards and the reset calibration line is flush with the top surface of the valve seat. This utility model is easy to operate, shortens maintenance time, and thus ensures production efficiency.
