Abstract

The utility model discloses a high pressure slide gate which is characterized in that an integrated door-shaped slide is arranged on the back side of the gate, the door-shaped slide is located at the top and two sides of the gate and can also serve as a water seal to well reduce deformation of the integral structure and gate slot depth of the gate, and reduce cavitation and cavitation erosion phenomena of the gate slot during overcurent, thereby facilitating safe operation of the gate. The door-shaped slide is slidingly connected with an H-shaped rail consisting of two lines of main rails on the downstream of the gate slot and a door header and the contact face is a stainless steel seat plate, so that the track is effectively prevented from being rusted, and the abrasion loss of the slide and the track during operation is reduced. In addition, a flat gasket and a rubber gasket are arranged on a bolt for connecting the slide with the gate. The rubber gasket is arranged below the flat gasket, thereby effectively preventing water leakage of the gate.

Description

A kind of high pressure chute gate

Technical field

The utility model relates to a kind of high pressure chute gate, belongs to Hydraulic and Hydro-Power Engineering gate technical field.

Background technology

At present, in Hydraulic and Hydro-Power Engineering, high pressure chute gate generally adopts the pattern of downstream sealing, arranged downstream two row slideway supportings.The top of this kind of pattern gate is an elongated continuous beam without supporting, relatively boundary beam rigidity a little less than, at dash head, surpass in 150m situation, gate top can be under high-pressure situations the moderate finite deformation of side generation downstream, may cause top seal compressive strain excessive and destroy, drainage occurs, and slideway and water seal will arrange separately, the gate slot degree of depth is larger, gate slot HYDRODYNAMIC CONDITION RELATING TO is poor, easily there is cavitation and cavitation erosion phenomenon, affect the stagnant water effect of gate, so the gate of prior art is left to be desired.

Utility model content

In order to address the above problem, the utility model provides a kind of high pressure chute gate.The slideway of this gate is an integral door type frame construction, the top and the both sides that are arranged on gate double as water seal, can reduce preferably the degree of depth of the integrally-built distortion of gate and gate slot, while reducing overcurrent, the generation of the cavitation and cavitation erosion phenomenon of gate slot, is conducive to the safe operation of gate.

The utility model is achieved by following technical solution.

A high pressure chute gate, comprises sluicing runner and is arranged at the gate in sluicing runner, in described sluicing runner, is provided with the gate slot corresponding with gate, at the back side of gate, is provided with an integral door type slideway, and the top and the both sides that are positioned at gate double as water seal.

The H type track sliding that the two row backbones in described door type slideway and gate slot downstream and lintel form is dynamically connected.

Described door type slideway is connected with gate by bolt.

Described H type track is stainless steel seat board with door type slideway contact surface.

Described bolt is provided with plain cushion and rubber pad with the junction of door type slideway, and wherein rubber pad is arranged on plain cushion below.

The beneficial effects of the utility model are:

Compared with prior art, floodgate sliding rail described in the utility model is an integral door type framework pattern, because the top of gate and both sides are equipped with continuous slideway supporting, thereby reduced preferably the integrally-built distortion of gate, another slideway doubles as water seal, reduced the degree of depth of gate slot, while having reduced overcurrent, the generation of gate slot cavitation and cavitation erosion phenomenon, is conducive to the safe operation of gate.Simultaneously, slideway adopt there is low-friction coefficient, abrasion resistance is high, elasticity and the good high strength composite of self-reparability, rely on the compressive strain of slideway under high-pressure situations to guarantee and the tight sealing of contacting of water seal seat board, and track and slideway contact surface are stainless steel seat board, effectively prevent that track from getting rusty, the wear extent of slideway and track while having reduced operation, because the connecting bolt of slideway and gate is provided with plain cushion and rubber pad, and rubber pad is arranged on below plain cushion, effectively prevented leaking of gate.

The specific embodiment

Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.

As shown in Figures 1 to 10, a kind of high pressure chute gate described in the utility model, comprise sluicing runner 1 and be arranged at the gate 2 in sluicing runner 1, in described sluicing runner 1, be provided with the gate slot corresponding with gate 23, back side at gate 2 is provided with an integral door type slideway 4, is positioned at top and the both sides of gate 2.

Described door type slideway 4 is dynamically connected with the two row backbones 5 in gate slot 3 downstreams and the H type track sliding of lintel 6 compositions.

Described door type slideway 4 is connected with gate 2 by bolt 8.

Described H type track is stainless steel seat board 7 with door type slideway 4 contact surfaces.Can effectively prevent that like this track from getting rusty, the wear extent of slideway and track while simultaneously having reduced operation.

Described bolt 8 is provided with plain cushion 9 and rubber pad 10 with the junction of door type slideway 4, and wherein rubber pad 10 is arranged on plain cushion 9 belows.Below rubber pad 10 is arranged on, effectively prevented leaking of gate 2.

Door described in the utility model type slideway doubles as water seal, adopt there is low-friction coefficient, abrasion resistance is high, elasticity and the good high strength composite of self-reparability are made.Like this, can rely on the compressive strain of slideway under high-pressure situations to guarantee and the tight sealing of contacting of water seal seat board, and then improve its sealing performance.
