Embodiment Construction

[0021] Such as figure 1 , figure 2 and image 3 As shown, the liquid bag type large-diameter square pipe culvert gate in this embodiment includes a lock chamber 5, a sealing ring a19, a sealing ring b20, a support frame 15, a gate, a liquid bag expansion body 18, a tension spring 17, and a door lock 23. The cover plate 1 and the base 2 have a connecting port a3 at the front end of the culvert gate lock chamber 5, and a connecting port b4 at the rear end of the lock chamber 5. The connecting port a3 and the connecting port b4 are located at the The lock chamber 5 described above is horizontally connected to form a horizontal pipeline. The inner wall of the horizontal pipeline is located directly below the lock chamber to form a groove matching the bottom of the gate. There is a vertically upward tunnel in the lock chamber 5. The entire Described lock chamber 5 is like " tee " shape. The connecting port a3, the connecting port b4, and the inner hole of the lock chamber 5 are...

Abstract

The invention discloses a hydraulic-bag-type large-diameter square pipe culvert gate and a using method thereof. Two-way flow of liquids can be achieved. By adopting a pipe culvert, a lock chamber andother devices with diameters, the lockage head loss is small; a gate bevel and a highly-elastic hollow sealing ring are adopted for sealing, and the the dual sealing effect is good; a hydraulic bag expansion unit and a tension spring for opening and closing are located in the gate, the construction is highly integrated, the structure is compact, and the occupied space is small; according to the types of the liquids flowing in the pipe culvert, the liquids of different types are selected and injected into the hydraulic bag expansion unit for opening and closing the gate, and cross contamination is avoided; the tension spring lifts the gate and is reliable in performance; a door lock for a hydraulic bag is arranged to control the full-open or full-close state of the gate; a gate lock sensoris arranged to facilitate automatic control. The hydraulic-bag-type large-diameter square pipe culvert gate has the advantages of being safe, reliable, excellent in airtight performance, capable of achieving automatic control, flexible in opening and closing, compact in construction, small in size, low in energy consumption and the like, and is a general hydraulic machine.

Description

technical field [0001] The invention relates to the technical field of hydraulic general machinery, in particular to a liquid bag type large-diameter square pipe culvert gate and a method for using the same. Background technique [0002] At present, large-diameter pipe culverts are required in hydraulic structures, pumping stations, siphon pipe stations, ship locks, water plants, sewage treatment plants, petrochemical plants, and oil fields. The gate of the diameter pipe culvert has problems such as complex opening and closing structure, large volume, large head loss, and unsatisfactory airtightness. Contents of the invention [0003] The purpose of the present invention is to make up for the defects of the prior art. Aiming at the shortcomings of the existing large-diameter square pipe culvert valves, the present invention proposes a liquid bag type large-diameter square pipe culvert gate, which integrates the opening and closing equipment with the gate. It not only adapt...
