Description

Case tubular type choke waterpower floats port valve device

Technical field

The technical field of choke taste drainage equipment is the utility model is related to, more particularly to subway tunnel ventilating shaft group catch pit Choke drainage equipment technical field.

Background technology

Subway tunnel ventilating shaft group sumping, existing ventilating shaft group catch pit individual drainage pumping system as shown in Figure 1, 2, Both ends set ventilating shaft group respectively AT STATION, each group set respectively 1 new ventilating shaft A, 1 removing shaft B and 2 piston vent C1, C2.In order that environmentally friendly smooth, the general outdoor layout of ventilating shaft group of tunnel ventilation ventilation；In addition, to exclude rainwater and seepage in ventilating shaft Water and ventilation environmental protection ring control is taken into account, each ventilating shaft catch pit D sets individual row water pump PB drainings and disappeared to ground energy dissipating well F respectively After energy, then it is discharged into gully E and is responsible for exclusion to municipal drainage.

In a ventilating shaft group finite region, each ventilating shaft set respectively 1 catch pit D and 2 sets of draining pump PB equipment and Its a set of self-control cabinet ZG System drainage.There are 2 ventilating shaft groups at general station, need to set 16 sets of draining pump PB equipment and corresponding self-control cabinet ZG systems；In addition, often covering drainage system facility, corresponding energy dissipating well F and gully E need to be set just to be discharged into municipal administration on ground.Cause This, causes construction facility investment big, takes up an area more；Drainage system electric equipment is more, maintenance management is numerous and diverse, maintenance cost is high.

The content of the invention

The utility model for solve known technology present in technical problem, and one kind is provided can choke taste and can waterpower The case tubular type choke waterpower of draining floats port valve device.The present apparatus is using the sealed rectangular body in casing in water buoyancy and deadweight masterpiece Automatic lifting under, reach the valve gear for the passage formation opened automatically or in blocking device.

The utility model is adopted the technical scheme that to solve technical problem present in known technology：

One plants case tubular type choke waterpower floats port valve device, and the device profile is rectangular-shaped in threeway, including the casing of rectangle and Horizontal short tube, the casing and short tube UNICOM；Active rectangle body, the outer wall upper and lower side of the cuboid are provided with the casing Sealing ring, the sealing ring and the closely connected sealing of cabinet wall are inlayed respectively, and limiting card is provided with the casing lower end inside wall, The cuboid hangs on limiting card, is blocked at the lower port of casing and the mouth of pipe of short tube, blocks the Inlet and outlet water of device Passage, the lower port of the casing are in the water inlet that opening port is also device, and the short tube is the delivery port of device.

The upper port of the casing is provided with case lid.

The upper side of the casing is provided with passage.

The passage is located at case lid lower edge.

The course of work of the utility model device：When catch pit is anhydrous, the cuboid in casing is acted on by from gravity Hang onto limiting card, the disengaging aquaporin blocked in casing, that is, block ventilating shaft group ventilation draining communicating pipe system Taint of odour, meet the requirement of environmental protection；When catch pit has water, the water inlet of device is in the square in water seal gas-blocking state and casing Body is acted on automatic rise by water buoyancy, that is, has been opened the drainage channel in device box, realized choke taste hydraulic automatism draining Function.

The utility model has the advantages and positive effects of：

The present apparatus is arranged on the water inlet pipe mouth of subway ventilating shaft catch pit internal drainage cross over pipe, using water buoyancy with from gravity The structure of the air-tight movable cuboid of effect, it can prevent each catch pit of ventilating shaft ventilation from passing through cross over pipe taint of odour；It can make again each Sumping is flowed to by cross over pipe in the catch pit for setting draining pump, is discharged by the draining pump of the catch pit is unified；This Device is without electric energy, substantially non-maintaining, 6 sets of a need, can need to set 16 instead of existing 2 ventilating shaft group individual drainage systems in subway station 12 appliances in platform draining pump, can also reduce the setting of 3, ground energy dissipating well and 3 gullys, instead of major part The draining pump appliance that catch pit is set, greatly reduces construction investment and operation management maintenance cost, reaches low-carbon ring The purpose of guarantor.

Embodiment

For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate Accompanying drawing describes in detail as follows：

Referring to Fig. 3, it is present apparatus Z that a plants case tubular type choke waterpower, which floats port valve device, present apparatus Z profiles are in threeway rectangle Shape, including the casing 2 of rectangle and horizontal short tube 3, casing 2 and the UNICOM of short tube 3；Active rectangle body 4, rectangle are provided with casing 2 The outer wall upper and lower side of body 4 inlays sealing ring 5, sealing ring 5 and the closely connected sealing of the inwall of casing 2 respectively, is set on the lower end inside wall of casing 2 Limiting card 7 is equipped with, cuboid 4 hangs on limiting card 7, is blocked at the lower port of casing 2 and the mouth of pipe of short tube 3, blocks The disengaging aquaporin of device, the lower port of casing 2 are in the water inlet 8 that opening port is also device, and short tube 3 is the delivery port of device.
