Description

Plunger 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 management, intensive setting；Existing ventilating shaft group catch pit individual drainage pumping system such as Fig. 1,2 institutes Show, both ends set ventilating shaft group respectively AT STATION, and each group sets 1 new ventilating shaft A, 1 removing shaft B and 2 piston vents respectively C1、C2；In a ventilating shaft group finite region, each ventilating shaft sets 1 catch pit D and 2 sets of draining pump PB equipment and its 1 respectively Cover self-control cabinet ZG System drainages.In order that environmentally friendly smooth, the general outdoor layout of ventilating shaft group of tunnel ventilation ventilation；In addition, to exclude Rainwater and percolating water and ventilation environmental protection ring control is taken into account in ventilating shaft, each ventilating shaft catch pit D sets individual row water pump PB rows respectively Water is to after ground energy dissipating well F energy dissipatings, then is discharged into gully E and is responsible for municipal drainage and excluded.

There are 2 ventilating shaft groups at general station, need to set 16 sets of draining pump PB equipment and its corresponding self-control cabinet ZG systems；In addition, often Drainage system facility is covered, corresponding energy dissipating well F and gully E need to be set just to be discharged into municipal administration on ground.Therefore, cause to build facility Investment is 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 plunger type choke waterpower of draining floats port valve device.Air-tight movable plunger is set in the column jecket of the present apparatus, floated using plunger in water Automatic lifting under power or self-gravity action, 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：

A kind of plunger type choke waterpower floats port valve device, and the device profile be in threeway tubulose, including column jecket and level is short Pipe, column jecket and short tube UNICOM；Movable plunger is provided with the column jecket, the profile of the plunger is in the form of a column, the outer wall of the plunger Sealing ring, the sealing ring and the closely connected sealing of column jecket inwall are inlayed in upper and lower two ends, are set on the column jecket lower end inside wall Limited location card, the plunger are seated on limiting card, are blocked at the lower port of column jecket and the mouth of pipe of short tube, are blocked device Aquaporin is passed in and out, the column jecket lower port is also the water inlet of device in opening port, and the short tube is the delivery port of device.

The upper port of the column jecket is provided with cap.

The upper side of the column jecket is provided with passage.

The passage is located at cap lower edge.

The course of work of the utility model device：When catch pit is anhydrous, the plunger in column jecket from gravity fall due to hindering Fill on the disengaging aquaporin in device, that is, block the taint of odour of ventilating shaft group ventilation draining communicating pipe system, realize resistance The purpose of smell；When catch pit has water, device water inlet is floated in the movable plunger in water seal gas-blocking state and column jecket in water Float automatically under power effect, drainage channel is open-minded, realizes the function of choke taste hydraulic automatism draining.

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 plunger of effect, it can prevent each catch pit of ventilating shaft ventilation from passing through cross over pipe taint of odour；Each collection can be made again Puddle draining 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 dress Put without electric energy, substantially non-maintaining, 6 sets of a need, can need to set 16 drainings instead of 2, a station ventilating shaft group individual drainage system 12 appliances in pump, can also reduce the setting of 3, ground energy dissipating well and 3 gullys, instead of most of catch pit The draining pump appliance of setting, greatly reduces construction investment and operation management maintenance cost, reaches the mesh of low-carbon environment-friendly 's.
