Description

Gas drainage draining air-stopping valve

Technical field

The utility model relates to the discharger of condensed water in a kind of gas, specifically a kind of gas drainage draining air-stopping valve.

Background technique

At present, discharge method for condensed water in gas or the gas utilities, drain valve, hydathode and the mode that manually discharges water are arranged, suitable cleaning gas or the non-toxic gas facility that is used in elevated pressures of drain valve, the general hydathode and the mode that manually discharges water of adopting on the gas of lower pressure or gas utilities.In the gas of the lower pressure of the timely draining of needs, modal is various coal gas, image height producer gas, coke-stove gas, coal gas of converter, producer gas, at present on the coal gas de-water, in the enterprise method commonly used be with the automatic draining of coal gas drainer or manually valve regularly discharge water.Valve regularly discharges water very dangerously manually, generally seldom adopts; Use the self-draining deficiency of coal gas drainer to be: when fluctuation appears in gas pressure, if gas pressure is higher than the pressure that coal gas drainer can bear, coal gas drainer will puncture, thereby there is potential safety hazard, in order to stop the generation of this phenomenon, someone adopts sense cell and on the coal gas sink drain mortor operated valve is set, coal gas drainer is closed when coal gas drainer punctures by automatic control system, but this kind method is complicated, and be throttle down just after coal gas drainer punctures, there is certain lag time, reduced the Security of operation.

Summary of the invention

The purpose of this utility model is to provide a kind of and the condensed water of gas or gas in time can be discharged, and intercepts gas or gas again effectively and reveals gas drainage draining air-stopping valve safe and convenient to use.

In order to reach above purpose, the technological scheme that the utility model adopted is: this gas drainage draining air-stopping valve, by valve body, import and export mixes, import is located at the upper end of valve body, and outlet is located at the lower end of valve body, it is characterized in that at valve body chamber internal fixation upper holder, the middle part of slide bar is located in the through hole at fixing frame middle part, the upper end of slide bar is upper float fixedly, the fixing blocking device of going up in lower end, and the interior edge of blocking device and outlet adapts.

Described blocking device, by connecting rod, spacing sealing plate, slipper seal sheet and base plate constitute, spacing sealing plate is fixed on the lower end of slide bar, the upper/lower terminal of connecting rod is separately fixed on spacing sealing plate and the base plate, be provided with the runner of indent on the sidewall of connecting rod, the slipper seal sheet is set on the connecting rod.

The fixing filter screen of going up in the top of the inner chamber of described valve body.

The beneficial effects of the utility model are: combine with traditional coal gas drainer by the utility model, condensed water in gas or the gas in time can be discharged, prevent the leakage of gas or gas again effectively, make coal gas drainer accomplish that a draining is air tight, safe and convenient to use, improve the coal gas drainer device ', reduced production accident effectively.

Embodiment

Make the utility model with reference to accompanying drawing 1,2.This gas drainage draining air-stopping valve, by valve body 1, import 2 and outlet 3 constitute, import 2 is located at the upper end of valve body 1, outlet 2 is located at the lower end of valve body 1, import 2 is connected with the sink drain that carries out the gas draining, outlet 3 is connected on the gas drainage, it is characterized in that at valve body 1 chamber internal fixation upper holder 7, the middle part of slide bar 6 is located in the through hole at fixing frame 7 middle parts, the upper end of slide bar 6 is upper float 5 fixedly, the fixing blocking device 8 of going up in lower end, and blocking device 8 adapts with the interior edge of outlet 3, by fixing frame 7, the one, supporting floating body 5, two, the levitation height of qualification buoyancy aid 5, the 3rd, be blocking device 8 location, make blocking device 8 and outlet 3 close fit, shutoff is tight.

Described blocking device 8, constitute by connecting rod 81, spacing sealing plate 82, slipper seal sheet 83 and base plate 84, spacing sealing plate 82 is fixed on the lower end of slide bar 6, the upper/lower terminal of connecting rod 81 is separately fixed on spacing sealing plate 82 and the base plate 84, be provided with the runner 85 of indent on the sidewall of connecting rod 81, slipper seal sheet 83 is set on the connecting rod 81.

The fixing filter screen 4 of going up in the top of the inner chamber of described valve body 1, can take out impurity in the water by filter screen 4, prevent that impurity from falling into the bottom, influence the sealing effect between the edge in slipper seal sheet 83 and the outlet 3, in order to process with easy to maintenance, valve body 1 can be divided into three sections of upper, middle and lower, after the processing, be connected and fixed with bolt again and be one respectively.

In use, the utility model is installed on the sink drain of drainage (as coal gas drainer), be positioned at water surface below, when gas main's internal pressure is normal pressure, self buoyancy by buoyancy aid 5 is mentioned blocking device 8, buoyancy aid 5 and blocking device 8 swim on the fixing frame 7, blocking device 8 and export 3 between keep ultimate range, guarantee the normal drainage of condensed water, when gas main's internal pressure has fluctuation, when pressure surpassed the pressure that drainage (as coal gas drainer) can bear, under the effect of gas pressure, the water level in drainage (as the coal gas drainer) sink drain moved down, buoyancy aid 5 and blocking device 8 also move down with water level, when water level moves down into certain position, slipper seal sheet 83 will export 3 internal orifice covering, when water level continues to move down, spacing sealing plate 82 can drop on the slipper seal sheet 83, the through hole at slipper seal sheet 83 centers is blocked, and gas and condensed water can not flow downward again like this, and the condensed water in the gas is deposited collection in valve body 1 chamber; When water level rises to certain altitude, buoyancy aid 5 in the valve body 1 is upwards mentioned slide bar 6, move on the spacing sealing plate 82, the liquid conducting that runner 85 on the connecting rod 81 is upper and lower with slipper seal sheet 83, eliminate the gas pressure that bears above the slipper seal sheet 83, the less buoyancy of buoyancy aid 5 usefulness is mentioned slipper seal sheet 83, and the condensed water in the gas sink drain can enter draining enforcement (as coal gas drainer) drainage by exporting 3 again.After the pressure recovery of gas is normal, liquid level in the valve body 1 is recovered normal water level, draining is implemented (as coal gas drainer) and is returned to normal hull-borne again, like this, condensed water among the gas main can be discharged smoothly, and gas always is blocked in the front of blocking device 8, can discharge the condensed water in toxic gas or the flammable explosive gas, gas leakage occurs in the time of preventing draining effectively again, guaranteed safety in production.

The utility model can be installed on the sink drain of vertical coal gas drainer, horizontal coal gas drainer, and will be installed in below the normal draining liquid level of coal gas drainer, so that buoyancy aid 5 and blocking device 8 swim on the fixing frame 7, guarantees the unimpeded of draining; Press the below of coal gas drainer during the utility model can be installed in, when manually discharging water, play smooth draining and the effectively only effect of gas.Combine with traditional coal gas drainer by the utility model, make coal gas drainer accomplish that a draining is air tight, improved the coal gas drainer equipment performance, reduce production accident effectively.
