Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to a multifunctional high-pressure equipment inlet and outlet valve. Background Technology

[0002] High-voltage equipment plays a crucial role in industrial production and many other fields, and the inlet and outlet valves, as an indispensable component for the stable operation of high-voltage equipment, are closely linked to technological development and application scenarios.

[0003] Traditional high-pressure equipment inlet and outlet valves have relatively simple functions, mostly only able to achieve basic opening and closing control. Early ordinary gate valves were used, which had a simple structure but poor sealing performance under high-pressure conditions. When the system pressure increased, leakage was prone to occur between the valve stem and the packing cavity. With the advancement of technology, some ball valves have been applied to the inlet and outlet of high-pressure equipment. Ball valves use the rotation of the ball to achieve opening and closing. Compared with gate valves, their sealing performance is improved and their operation is relatively convenient.

[0004] However, ball valves have drawbacks when dealing with fluids containing particulate impurities. Particles can easily get stuck between the ball and the valve seat, causing the valve to not close tightly or to jam, affecting the normal operation of high-pressure equipment. In high-pressure water flushing systems in mining operations, the water source often contains mud and sand particles. When using ball valves, frequent maintenance and cleaning work becomes a major problem, reducing production efficiency. Utility Model Content

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a multi-functional high-pressure equipment inlet and outlet valve is provided, including a valve body, a frame is movably connected to the inner wall of the valve body, a filter screen is fixedly connected to the inner wall of the frame, a fixed frame is fixedly connected to the side surface of the valve body, and a collection box is provided inside the fixed frame.

[0006] A fixing post is fixedly connected to the side surface of the valve body, a bolt is fixedly connected to the upper surface of the fixing post, a nut is threaded onto the side surface of the bolt, an installation block is fixedly connected to the side surface of the frame, an insert plate is provided on the inner wall of the fixing frame, a receiving groove is provided on the inner wall of the valve body, and a handle is provided on the valve body.

[0007] The above technical solution uses a filter screen to block particulate impurities in the water. The blocked particulate impurities fall into the receiving tank, preventing them from flowing into the device and affecting the opening and closing of the valve body, which could lead to obstruction or leakage. When it is necessary to clean particulate impurities, the top of the collection box can be opened or closed through the slide plate. When the box is closed, the particulate impurities fall downwards into the collection box. When closed, the water flow into the collection box is blocked. At this time, the collection box can be removed to clean the particulate impurities. If the filter screen is damaged and needs to be replaced, the frame can be removed and replaced.

[0008] The present invention is further configured such that the lower surface of the mounting block contacts the fixing post, and the upper surface of the mounting block contacts the nut.

[0009] The above technical solution allows the frame and valve body to be fixedly connected together using bolts and nuts.

[0010] The present invention is further configured such that the fixing frame is made of magnet, and an iron sheet is fixedly connected to one end of the insert plate, and the side surface of the iron sheet is magnetically connected to the fixing frame.

[0011] Through the above technical solution, the insert plate can be adsorbed onto the fixed frame to fix the position of the insert plate.

[0012] The present invention is further configured such that the receiving groove is connected to the fixing frame, a support block is fixedly connected to the side surface of the valve body, the lower surface of the support block and the lower surface of the fixing frame are located on the same horizontal plane, a vertical plate is fixedly connected to the upper surface of the support block, and an extension plate is fixedly connected to the side surface of the vertical plate.

[0013] Through the above technical solution, the support block and the fixing frame support both ends of the valve body when the device is placed on the ground, preventing the two ends from contacting the ground and being contaminated by soil or other contaminants.

[0014] The present invention is further configured such that a vertical rod is movably connected through the upper surface of the extension plate, an inclined plate is fixedly connected to the upper end of the vertical rod, a strong spring is fixedly connected to the lower surface of the inclined plate, and the side surface of the inclined plate contacts the handle.

[0015] Through the above technical solution, the inclined plate and the vertical plate can restrict the position of the handle after closing, preventing the valve body from being opened due to accidental contact or other external forces turning the handle.

[0016] The present invention is further configured such that the end of the strong spring away from the inclined plate contacts the extension plate, the side surface of the upright is provided with threads, and the side surface of the upright is threaded with a fastening nut.

[0017] The present invention is further configured such that a rod is movably connected through the side surface of the inclined plate, and a first spring is fixedly connected to the side surface of the rod, with one end of the first spring fixedly connected to the inclined plate.

[0018] With the above technical solution, the insert rod can be inserted into the slot of the handle, so that the inclined plate cannot be lowered due to accidental external force to release the position restriction on the handle.

[0019] The present invention is further configured such that a slot is provided on the side surface of the handle, a first magnet is fixedly connected to the inner wall of the slot, the insert rod is made of iron, and one end of the insert rod is magnetically connected to the first magnet.

[0020] The beneficial effects of this utility model are as follows:

[0021] By combining the frame, filter screen, collection box, insert plate, and receiving groove, this device can filter the incoming water flow while controlling the water flow interruption, blocking particulate impurities and preventing them from entering the device or high-pressure equipment. This effectively prevents particulate impurities from affecting the opening and closing of the device, causing valves to not close tightly or to jam. Furthermore, the blocked particulate impurities can be collected and removed for cleaning, preventing them from clogging the inside and affecting the water flow. When removing the collection box, the insert plate can also prevent water from flowing out of the pipe, avoiding waste. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figures 1-5 As shown, a multifunctional high-pressure equipment inlet and outlet valve of this embodiment includes a valve body 1. A frame 2 is movably connected to the inner wall of the valve body 1. A filter screen 3 is fixedly connected to the inner wall of the frame 2. The filter screen 3 can block particulate impurities in the water, preventing particulate impurities from entering the interior of the valve body 1, which could cause the valve body 1 to be obstructed from opening or closing or to leak due to improper closure. A fixing frame 4 is fixedly connected to the side surface of the valve body 1. A collection box 5 is set inside the fixing frame 4. The blocked particulate impurities are discharged into the collection box 5. Then, the collection box 5 can be removed to discharge the particulate impurities.

[0030] A fixing post 6 is fixedly connected to the side surface of the valve body 1. A bolt 7 is fixedly connected to the upper surface of the fixing post 6. A nut 8 is threadedly connected to the side surface of the bolt 7. The frame 2 and the valve body 1 can be fixedly connected together by the bolt 7 and the nut 8. When the filter screen 3 is damaged or needs to be replaced with a filter screen 3 of different aperture, the frame 2 can be removed. A mounting block 9 is fixedly connected to the side surface of the frame 2. The lower surface of the mounting block 9 contacts the fixing post 6, and the upper surface of the mounting block 9 contacts the nut 8.

[0031] The inner wall of the fixed frame 4 is provided with an insert plate 10. The insert plate 10 can be pulled out to allow the particulate impurities above to fall into the collection box 5. When inserted, it can block the water flow into the collection box 5, preventing water from flowing out and being wasted when the collection box 5 is removed to remove particulate impurities. The fixed frame 4 is made of magnet. One end of the insert plate 10 is fixedly connected to an iron sheet. The side surface of the iron sheet is magnetically connected to the fixed frame 4. The inner wall of the valve body 1 is provided with a receiving groove 11. The valve body 1 is provided with a handle 14. The opening and closing of the valve body 1 can be controlled by rotating the handle 14.

[0032] The receiving groove 11 is connected to the fixed frame 4. A support block 12 is fixedly connected to the side surface of the valve body 1. The lower surface of the support block 12 and the lower surface of the fixed frame 4 are on the same horizontal plane. The support block 12 and the fixed frame 4 cooperate to support the valve body 1 when the device is placed on the ground, so that the two ends of the valve body 1 are away from the ground, and the two ends of the valve body 1 are prevented from being contaminated by the soil or other contaminants on the ground.

[0033] A vertical plate 13 is fixedly connected to the upper surface of the support block 12, an extension plate 15 is fixedly connected to the side surface of the vertical plate 13, a vertical rod 16 is movably connected through the upper surface of the extension plate 15, and a slanted clamping plate 17 is fixedly connected to the upper end of the vertical rod 16. The slanted clamping plate 17 cooperates with the vertical plate 13 to restrict the position of the handle 14 after it is closed, so as to prevent the valve body 1 from being opened due to accidental contact with the handle 14 by external force.

[0034] A strong spring 18 is fixedly connected to the lower surface of the inclined plate 17. The side surface of the inclined plate 17 contacts the handle 14. The end of the strong spring 18 away from the inclined plate 17 contacts the extension plate 15. The side surface of the upright 16 is provided with threads. A fastening nut 19 is threadedly connected to the side surface of the upright 16. After the fastening nut 19 is removed, the inclined plate 17 can be removed and replaced.

[0035] A rod 20 is movably connected through the side surface of the inclined plate 17. A first spring 21 is fixedly connected to the side surface of the rod 20. One end of the first spring 21 is fixedly connected to the inclined plate 17. A slot 22 is provided on the side surface of the handle 14. The rod 20 can be inserted into the slot 22. This can prevent the inclined plate 17 from accidentally releasing the position restriction of the handle 14 due to external force when restricting the position of the handle 14. A first magnet 23 is fixedly connected to the inner wall of the slot 22. The rod 20 is made of iron. One end of the rod 20 is magnetically connected to the first magnet 23.

[0036] The working principle of this utility model is as follows: When this device is installed on high-pressure equipment, the water flows through the filter screen 3 before entering the high-pressure equipment. The filter screen 3 blocks the particulate impurities in the water. The particulate impurities slide down the filter screen 3 under their own weight and fall into the receiving groove 11. The filtered water enters the high-pressure equipment through the valve body 1, which can prevent particles from getting stuck inside the device, causing the valve body 1 to not close tightly or to be stuck in operation, thus affecting the normal operation of the high-pressure equipment. When it is necessary to remove particulate impurities, the insert plate 10 is pulled out and the particulate impurities fall into the collection box 5 installed below. After inserting the insert plate 10, the collection box 5 is removed and the particulate impurities can be poured out.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
