Description

Technical Field

[0001] The invention relates to the technical field of gate valves, and more specifically to a threaded signal gate valve. Background Art

[0002] A gate valve is a device that controls the flow of water through an opening and closing piece. The valve stem moves by rotating the handwheel, and the valve stem drives the valve plate to move up or down to perform opening and closing operations within the valve body.

[0003] When using a threaded signal gate valve to open and close the fluid, the gate of the flow channel of the existing threaded signal gate valve is prone to leakage due to its reduced sealing performance during long-term use.

[0022] The surface of the sealing buckle ring 43 is provided with gear strips; The inner surface of the arc-shaped retaining ring 455 is provided with a gear groove adapted to the gear bar. The gear groove and the gear bar are connected by a movable sleeve, which is used to achieve the mutual engagement of the gear bar when the gate structure as a whole is used to intercept and close the threaded signal gate valve, thereby strengthening the sealing fit between the two and improving the sealing performance of the gate valve.

[0023] The track frame 44 and the track plate 453 are arranged in anisotropic magnetic structures and are fitted together by sliding, and move up and down in coordination with the movable gate.

[0024] The limiting structure 46 is provided with two groups and is evenly and equidistantly installed on both sides of the track frame 44, and is integrated with the gate valve frame 41. It can cooperate with the telescopic filter to be in an extended state when the movable gate plate moves upward, thereby filtering impurities mixed in the circulating fluid and ensuring the effective circulation of the fluid.

[0025] The U-shaped frame plate 462 is disposed in an open shape facing the groove 47, and the opening cross-sectional area of ​​the U-shaped frame plate 462 is smaller than that of the groove frame 461; The cross-sectional shape of the groove frame 461 is consistent with the cross-sectional shape of the second limiting plate 4512, and the two are transitionally matched.

[0026] The surface of the movable sleeve 459 is provided with a hole that is movably fitted with the track support rod 464 , and the upper surface thereof is in contact with the end of the limit spring 465 .

[0027] The telescopic filter 4510 is a double-layer structure and a telescopic structure. A plurality of overflow holes are provided on the surface of the telescopic filter 4510, so as to filter out impurities mixed in the fluid. The upper and lower surfaces of the telescopic filter 4510 are respectively connected to the No. 1 sealing strip plate 457 and the No. 2 sealing strip plate 4511 with a movable and detachable structure, so that the telescopic filter can be replaced after being used for a period of time, so as to realize the recycling of the gate valve.

[0028] The top end of the adjusting connecting rod 452 passes through the gate valve cover 5 and is connected to the thread 2, and the upper part of the thread 2 is connected to the turntable 3, so that the gate structure 45 can be controlled through the cooperation of the thread and the turntable, thereby realizing the circulation and interception of the fluid.

[0029] The interior of the mounting hole column 6 is a hollow structure and is through-set with the gate valve frame 41 . The surface of the through hole inside the mounting hole column 6 is provided with mounting thread patterns for matching the installation of the external pipeline.

[0030] The specific implementation principle is as follows: when the gate valve is in a stationary state, the shut-off gate plates 454 arranged on the surfaces of both sides of the movable gate plate 451 intercept and seal the sealing buckle ring 43, and at the same time, the arc-shaped buckle ring 455 arranged on the surface of the shut-off gate plate 454 and the gear bar arranged on the surface of the sealing buckle ring 43 are engaged with each other to further strengthen the engagement connection between the two, thereby improving the gate plate structure 45 to intercept the fluid of the sealing buckle ring 43 and the flow pipe 42, thereby strengthening the sealing of the internal channel of the gate valve when it is stationary and avoiding leakage.

[0031] When the threaded signal gate valve needs to work, the setting of the turntable 3 and the thread 2 drives the adjusting connecting rod 452 connected thereto to move upward, thereby realizing the synchronous movement of the movable gate plate 451, and the intercepting gate plate 454 and the arc buckle 455 connected to the two side surfaces of the movable gate plate 451 are separated from the sealing buckle 43, thereby realizing the circulation of the fluid, and the lower surfaces of the two intercepting gate plates 454 are connected with supporting connecting plates 456, which cooperate with the supporting connecting plates 456 to drive the No. 1 sealing strip plate 457, the telescopic filter screen 4510 and the No. 2 sealing strip plate 4511 to move upward synchronously, and the No. 2 sealing strip plate 4511 moves to the groove frame 461. After reaching the top, the U-shaped frame plate 462 that cooperates with it limits the movement of the No. 2 limit plate 4512, thereby limiting the overall movement of the No. 2 sealing strip plate 4511. The No. 1 limit plate 459 arranged on both sides of the No. 1 limit plate 458 is penetrated by the track support rod 464. During the movement, the No. 1 limit plate 459 contracts the limit spring 465 arranged on the upper surface, and the telescopic filter 4510 is in an extended state while being pulled upward, thereby fitting the through hole position of the sealing buckle 43, so that after the fluid passes through the sealing buckle 43, the impurities mixed in it are filtered through the telescopic filter 4510.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
