Description

Technical Field

[0001] The invention relates to the technical field of high-pressure valve maintenance, in particular to a high-pressure large-caliber valve that is easy to operate and maintain. Background Art

[0002] High-pressure valves mainly play the role of cutting off and throttling in pipelines. Due to the widespread use of high-pressure technology, the performance of high-pressure valves in high-pressure systems directly affects the reliability, safety, work efficiency and service life of the entire system. It is particularly important in systems that require frequent pressure increase and pressure relief.

[0003] During the use of high-pressure valves, debris in the water flow will continue to accumulate in the valve. The debris accumulates on the inside of the valve, which can easily lead to valve blockage. Fixed valves need to be removed from the entire system during maintenance, which is very inconvenient.

[0008] Preferably, the rotating member includes an adapter, a rotating column and a crushing spike, the adapter is fixedly mounted on the bottom of the threaded sleeve, the rotating column is rotatably mounted on the bottom center of the adapter, the rotating column is movably mounted in the inner square groove of the fixed cylinder, and the crushing spike is evenly and fixedly mounted on the outer side of the rotating column.

[0009] Preferably, the crushing thorn includes a water retaining plate and a fixed tooth, the water retaining plate is fixedly mounted on one side of the crushing thorn through an elastic column, and the fixed tooth is fixedly mounted on a side of the water retaining plate close to the crushing thorn.

[0010] Preferably, the toggle member includes a fixed column, a sleeve tube, a toggle strip and an elastic strip, the fixed column is fixedly installed on the inner side of the fixed tube, the fixed column is arranged on the left side of the fixed block, the sleeve tube is movably sleeved on the outer side of the middle part of the fixed column, the toggle strip is mirror-fixed on the outer side of the sleeve tube, the elastic strip is fixedly installed on the side of the sleeve tube close to the inner side of the front face of the fixed tube, and the end of the elastic strip away from the sleeve tube is connected to the inner side of the front face of the fixed tube.

[0011] The present invention provides a high-pressure large-caliber valve that is easy to operate and maintain. It has the following beneficial effects:

[0012] (1) This high-pressure large-diameter valve that is easy to operate and maintain can tear off debris carried in the water flow through a disassembly mechanism and a control mechanism, thereby preventing larger debris from clogging the inside of the valve. Furthermore, the inside of the water valve can be cleaned by separating the top valve from the water valve, thereby facilitating valve maintenance.

[0013] (2) This high-pressure large-diameter valve is easy to operate and maintain. When the water flow impacts the rotating plate, the rotating plate compresses the spring sheet and stretches the elastic rubber. When the restoring force of the spring sheet and the elastic rubber is greater than the water flow impact force, the rotating plate rotates on the left side of the fixed block, and the rotating plate continuously swings back and forth inside the fixed cylinder, blocking larger debris on the side of the water inlet. When the rotating plate rebounds, the larger debris is torn apart by the conical thorns.

[0014] (3) The high-pressure large-diameter valve is easy to operate and maintain. The rotating plate on the inner side of the fixed cylinder forms resistance to the water flow, so that the flow rate on the square groove side of the fixed cylinder is accelerated. The water retaining plate increases the force-bearing area between the one side of the crushing thorn and the water, so that the crushing thorn is driven by the thrust of the water flow to rotate the rotating column at the bottom of the adapter. The rotating crushing thorn further crushes the debris in the water flow, preventing the debris in the water flow from adhering to the inner side of the valve during the flow and causing the valve to be blocked.

[0015] (4) This high-pressure large-diameter valve is easy to operate and maintain. When the rotating column rotates, the outer crushing spikes contact one end of the toggle bar, so that the toggle bar drives the sleeve tube to rotate outside the middle of the fixed column. The rotating sleeve tube causes the elastic bar to deform under force. Under the cooperation of the deformation restoring force and the toggle force of the crushing spikes, the toggle bar swings back and forth. The end of the toggle bar close to the rotating plate contacts the movable rotating plate, which speeds up the rotation frequency of the rotating plate, thereby enhancing the tearing effect of the conical spikes on larger debris.

The rotating shaft 54 ​​is movably installed on the inner side of the movable groove 53.

The toggle piece 59 includes a fixed column 591, a sleeve cylinder 592, a toggle strip 593 and an elastic strip 594. The fixed column 591 is fixedly installed on the inner side of the fixed cylinder 51, the fixed column 591 is arranged on the left side of the fixed block 52, the sleeve cylinder 592 is movably sleeved on the outer side of the middle part of the fixed column 591, the toggle strip 593 is fixedly installed on the outer side of the sleeve cylinder 592 in a mirror image, and the elastic strip 594 is fixedly installed on the side of the sleeve cylinder 592 close to the inner side of the front face of the fixed cylinder 51, and the end of the elastic strip 594 away from the sleeve cylinder 592 is connected to the inner side of the front face of the fixed cylinder 51.

[0030] When in use, the water valve 1 is connected to the water pipeline, the right end of the water valve 1 is connected to the water inlet, and the left end is connected to the water outlet. When the water valve 1 is turned on, water flows into the fixed cylinder 51, and the water flows impact the rotating plate 55, so that the rotating plate 55 compresses the spring sheet 57 and stretches the elastic rubber 56. When the restoring force of the spring sheet 57 and the elastic rubber 56 is greater than the impact force of the water flow, the rotating plate 55 rotates on the left side of the fixed block 52 under the action of the rotating shaft 54, so that the rotating plate 55 continuously swings back and forth inside the fixed cylinder 51, blocking larger debris on the side of the water inlet, and tearing the larger debris through the conical thorns 58 when the rotating plate 55 rebounds. The inner side of the valve 46 forms a resistance to the water flow, so that the flow speed of the square groove side of the fixed cylinder 51 is accelerated, thereby driving the rotating member 46 to work. The water retaining plate 4631 increases the force-bearing area of ​​the crushing thorn 463 on one side and the water, so that the crushing thorn 463 drives the rotating column 462 to rotate at the bottom of the adapter 461 under the thrust of the water flow. The rotating crushing thorn 463 further crushes the debris in the water flow, preventing the debris in the water flow from adhering to the inner side of the valve during the flow and clogging the valve. When the rotating column 462 rotates, the outer crushing thorn 463 contacts one end of the toggle bar 593, so that the toggle bar 593 drives the sleeve cylinder 592 to rotate on the outer side of the middle part of the fixed column 591, and the rotating sleeve cylinder 592 causes the elastic strip 594 to deform under force. Under the cooperation of the deformation restoring force and the toggling force of the crushing spike 463, the toggling strip 593 swings back and forth. The toggling strip 593 near the rotating plate 55 does not contact the movable rotating plate 55, so that the rotation frequency of the rotating plate 55 is accelerated, thereby enhancing the tearing effect of the conical spike 58 on larger debris. When closing the valve, the rotating handle 43 is rotated, the threaded rod 44 is rotated, and the threaded sleeve 45 moves upward in the cavity inside the upper end of the water valve 1, and drives the rotating member 46 connected thereto to move upward. When the rotating member 46 is completely retracted to the cavity inside the upper end of the water valve 1, the water flow does not stop in the square groove of the fixed cylinder 51. Under the resistance of the rotating member 46, the water flow rate is accelerated, the rotation amplitude of the rotating plate 55 inside the fixed cylinder 51 is increased, and the rotating shaft 54 ​​is movable in the movable groove 53. When the elastic rubber 56 and the spring sheet 57 drive the rotating plate 55 to return, the elastic force applied by the spring sheet 57 causes the rotating plate 55 to be stuck in the groove inside the fixed cylinder 51, thereby stopping the water flow at the water inlet of the fixed cylinder 51. At this time, the connecting bolts at the connecting disk 1 41 and the connecting disk 2 42 are loosened, and the clamping column 3 is pushed to be stuck in the groove at the upper end of the threaded rod 44, so that the top valve 2 is separated from the water valve 1, and the rotating member 46 is pulled out from the inside of the water valve 1 along with the threaded rod 44, which facilitates the cleaning of the rotating member 46.
