Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a valve assembly for fluid loading and unloading. Background Technology
[0002] When transporting fluid goods, it is necessary to transfer the fluid goods from the freight station to transport vehicles such as tank cars, trains, or ships, or to transfer the fluid goods from the transport vehicle to the freight station. Therefore, loading and unloading arms are required, which are the conveying pipelines connecting the freight station and the transport vehicle. Existing technical solutions have the following drawbacks: they do not have corresponding anti-clogging structures. When loading and unloading some viscous fluids, accumulation and blockage are prone to occur during the process, causing the valves to malfunction. The valves also need to be disassembled for treatment, which is troublesome, time-consuming, and labor-intensive. Therefore, a valve assembly for fluid loading and unloading is proposed to solve the above-mentioned problems. Utility Model Content

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides a technical solution: a valve assembly for fluid loading and unloading, including a valve body 1, an inlet pipe 2 extending to the right side of the inner wall of the valve body 1, a connecting pipe 3 fixedly installed at one end of the right side of the inlet pipe 2, an outlet pipe 4 extending to the left side of the inner wall of the valve body 1, an installation cover 5 movably installed at one end of the left side of the outlet pipe 4, a discharge pipe 6 extending to the bottom of the inner bottom wall of the discharge pipe 4, the bottom of the discharge pipe 6 being designed with a constriction, a frame 7 fixedly installed on the top of the valve body 1, a switching mechanism 8 extending to the inner side of the valve body 1 provided on the top of the frame 7, and an anti-blocking mechanism 9 extending to the inner side of the inlet pipe 2 and the outlet pipe 4 provided on the outer side of the frame 7.
[0023] The switching mechanism 8 includes a stabilizing plate 81. The stabilizing plate 81 is fixedly installed on the inner top wall of the frame 7. The inner side of the stabilizing plate 81 is rotatably connected to a screw 82 extending to the top of the frame 7. One end of the screw 82 extends to the bottom of the stabilizing plate 81. The outer side of the screw 82 is threadedly connected to a stop block 83 extending to and fitting against the inner side of the valve body 1. A turntable 84 is fixedly installed on the top of the screw 82. Slide grooves 85 are provided on both the left and right sides of the inner wall of the frame 7. Limiting blocks 86 are fixedly installed on both the left and right sides of the stop block 83, respectively slidingly connected to the two slide grooves 85.
[0024] The fluid enters the feed pipe 2 through the connecting pipe 3 and then flows through the valve body 1. At this time, the baffle 83 is in a raised state. The fluid passes through the discharge pipe 4 and is finally discharged through the discharge pipe 6. The baffle 83 presses down to seal the valve body 1, cutting off the connection between the feed pipe 2 and the discharge pipe 4. The fluid path is physically blocked, thereby closing the valve.
[0025] The top of the stop block 83 is provided with a threaded groove, the size of which is adapted to the screw 82. The inner top wall of the valve body 1 is provided with a mounting hole adapted to the stop block 83, and a sealing ring is provided on the inner wall of the mounting hole.
[0026] The anti-clogging mechanism 9 includes a slide plate 91. Two slide plates 91 are slidably installed on the outer side of the frame 7. A pull ring 92 is fixedly installed on the top of the slide plate 91. A connecting plate 93 is fixedly installed between the front and rear sides of the two slide plates 91. A vertical plate 94 is fixedly installed on the bottom of the slide plate 91. The two vertical plates 94 extend to the inner side of the feed pipe 2 and the discharge pipe 4, respectively. A ring body 95 is slidably installed on the inner side of the feed pipe 2 and the discharge pipe 4. A vertical plate 96 is fixedly installed between the upper and lower sides of the inner wall of the ring body 95. An installation rod 97 is fixedly installed on one side of the vertical plate 96. An anti-clogging blade 98 is fixedly installed on the outer side of the installation rod 97. A connecting rod 99 is rotatably connected between the vertical plate 94 and the vertical plate 96.
[0027] The interior of the slide plate 91 has through holes that fit the inner wall of the frame 7. The two slide plates 91 are open on opposite sides and are symmetrically distributed. The outside of the pull ring 92 is covered with a sponge sleeve. The sponge sleeve of the pull ring 92 reduces hand fatigue and is suitable for frequent operation scenarios. The inner top walls of the feed pipe 2 and the discharge pipe 4 have limiting holes that fit the vertical plate 94.
[0028] When in use, rotate the turntable 84, move the stop 83 upward, and observe the pressure gauges on both sides of the valve body 1 to confirm the open status. Before loading or unloading high-viscosity or impurity-containing fluids, pull the pull ring 92 several times to move the anti-clogging blade 98 and reduce the risk of adhesion. If abnormal flow is found, immediately pull the pull ring 92 and hold it for three to five seconds, then push the pull rod 92 to reset. Repeat two to three times until the flow is restored. Lubricate regularly by adding grease to the slide groove 85 and the screw 82 to ensure smooth movement of the stop 83. Remove the mounting cover 5 monthly to check the wear of the anti-clogging blade 98 and replace it if necessary. After closing the valve quarterly, inject test liquid and observe whether there is any leakage at the mounting cover 5. The switching mechanism 8 and the anti-clogging mechanism 8 operate independently to avoid the unclogging operation affecting the valve's sealing performance. The anti-clogging blade 98 and the ring 95 can be quickly disassembled and replaced to adapt to different fluid characteristics.
[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0030] In summary, this fluid loading and unloading valve assembly, by incorporating an anti-clogging mechanism 9, connects the slide plate 91 and the ring body 95 via a connecting rod 99 and a vertical plate 94. When material blockage occurs, pulling the ring 92 upward causes the slide plate 91 to slide along the frame 7, thereby raising the vertical plate 94. With the cooperation of the connecting rod 99, the vertical plate 94 moves upward, causing the vertical plate 96 and the ring body 95 to move. The anti-clogging blade 98 and the mounting rod 97 move synchronously with the vertical plate 96, breaking the blockage in the feed pipe 2 or the discharge pipe 4. This achieves the purpose of having an anti-clogging structure and solves the problem that without a corresponding anti-clogging structure, when loading and unloading some viscous fluids, accumulation and blockage can easily occur, causing the valve to malfunction and requiring disassembly for processing, which is troublesome, time-consuming, and labor-intensive.
