Abstract
The invention relates to a high sensitivity water drainer excess pressure protector which is produced by adding a sensitivity regulator and a gas-water separator before an excess pressure protector in prior art. The sensitivity regulator can thoroughly eliminate water drainer excess pressure protector or water drainer gas leakage preventing device, prevents a gas leakage excess pressure dead region, and can cut off leaking gas caused by an excess pressure quickly, accurately and tightly in the whole region when the gas pressure is bigger than practical water sealing pressure of the water drainer; the gas-water separator can eliminate water obstruction caused by that the water drainer drains water with a large amount and leads to automatic shut of the excess pressure and gas leakage preventing device. The sensitivity regulator is a U-shaped water sealing cavity composed of an upper inlet tube, a lower inlet tube, a hand hole, a lower output tube and an upper output tube of the sensitivity regulator; the gas-water separator is composed of a leading tube and a flow guide tube. The invented device is provided with no power requirement, automatic recognition, water draining when water exists, closing when gas exists, cabinet design, convenient installation and maintenance, and a long service life.
Description
Technical field
The present invention relates to gas pipe line drainage field, particularly a kind of excess voltage protector for high sensitivity drainer.
Background technique
Gas pipeline drainer overvoltage protection of the prior art or prevent the device of gas leakage; All exist the overvoltage protection dead band; When gas pressure just greater than the actual water seal pressure of hydathode when (gas pressure and the difference of water seal pressure of this moment are called the overvoltage protection dead band), this device can not cut off the coal gas that leaks immediately, has only when gas pressure during much larger than actual water seal pressure; Hydathode could move, the shutoff overvoltage coal gas that leaks.In addition, because a large amount of drainings of hydathode, and cause overvoltage protector or prevent that the gas leakage device from closing automatically, the draining that results in blockage, being easy to generate the gas pipe line load increases the weight of, and produces the danger of slump.
Summary of the invention
For solving the problem that existing technology exists, the purpose of this invention is to provide a kind of excess voltage protector for high sensitivity drainer, this device is through being provided with sensitivity regulator and moisture trap, and can make the dead band is zero, and draining is not obstructed when a large amount of draining of hydathode.
For realizing above-mentioned purpose, the present invention realizes through following technological scheme:
Excess voltage protector for high sensitivity drainer successively installs sensitivity regulator and moisture trap additional before the hydathode overvoltage protector; The upper outlet pipe of sensitivity regulator is connected with the moisture trap skirt; The moisture trap skirt is connected with hydathode overvoltage protector body import plate; The moisture trap draft tube outlets is formed excess voltage protector for high sensitivity drainer in hydathode overvoltage protector valve plate bottom; Described sensitivity regulator is connected to form by upper inlet pipe, lower inlet pipe, following outer pipe, upper outlet pipe successively; By dividing plate with the upper inlet pipe, the lower inlet pipe separates with following outer pipe, upper outlet pipe and the bottom communicates; Form U-shaped water seal cavity, bottom of device is provided with hand hole; The body that described moisture trap is formed by connecting by the α angle in skirt and its axis of honeycomb duct.
The height h of described sensitivity regulator dividing plate is 150-3000mm; Axis angle α between said moisture trap skirt and the honeycomb duct is 90 °-270 °; On said moisture trap skirt, honeycomb duct, body hand hole inside and closure plate, one or more guide plates are installed.
Described sensitivity regulator, moisture trap can jointly, also can be arranged separately on piston type hydathode overvoltage protector or the hydathode leakage preventer.
Compared with prior art, the invention has the beneficial effects as follows:
1, be provided with sensitivity regulator, can make overvoltage coal gas dead band is zero.When the normal draining of hydathode, sewage through hydathode outlet, sensitivity regulator upper inlet pipe, lower inlet pipe, following outer pipe, upper outlet pipe, flows out sensitivity regulator successively; When the overvoltage of hydathode coal gas, overvoltage coal gas flows into the upper inlet pipe of sensitivity regulator through the hydathode outlet; Overvoltage coal gas obtains savings in its lower inlet pipe, along with gas pressure increases, press to the lower end to liquid level; Before liquid level arrived the dividing plate lower end, overvoltage coal gas can not leak, when reaching the dividing plate lower end; Gas pressure has surpassed the dead band of hydathode overvoltage protector valve closing, and moment punctures ponding wherein outer pipe, upper outlet pipe and moisture trap under it passes through to overvoltage coal gas in following outer pipe bottom; Rapidly hydathode overvoltage protector valve plate is closed dead; Thereby in all processes of coal gas overvoltage, prevented overvoltage coal gas to leak, equalled zero in the dead band of overvoltage coal gas.
2, be provided with moisture trap, big current had nothing to do with close valve plate.Its working procedure is: when the normal draining of hydathode, sewage flows into the moisture trap skirt through the upper outlet pipe of sensitivity regulator, flows in the honeycomb duct then.Because the guide functions of honeycomb duct (or several guide plates); Make sewage walk around the valve plate of hydathode overvoltage protector; Crossed hydathode overvoltage protector water inlet short tube from surface current thereafter, in this process, even a large amount of water flows through; Still can walk around the valve plate of hydathode overvoltage protector, can not produce and impact it.Therefore, can not close valve plate, stop draining because of a large amount of drainings of hydathode; When the overvoltage of hydathode coal gas, the overvoltage coal gas that surpasses the dead band pours the moisture trap skirt by upper outlet pipe moment of sensitivity regulator, and with the liquid level in the honeycomb duct; Press to bottom and hydathode hand hole top; Thereby make in the slit of overvoltage coal gas between liquid level and honeycomb duct lower end (A point),, rush at the bottom of hydathode overvoltage protector valve plate with bigger moment; Rapidly valve plate is closed extremely, prevented overvoltage coal gas to leak.
The outstanding advantage of this device is: structure is extremely simple, does not have any movable piece, and its function is outstanding, reliable, zero dead band, and the tight prevention overvoltage coal gas of ability, draining in a large number, unblocked.Sensitivity regulator can be put aside the enough overvoltage coal gas that surpasses the dead band, and abrupt release is closed the valve plate of hydathode overvoltage protector rapidly, and making the dead band is zero; Moisture trap air-water separation effect is splendid, can make large amount of sewage walk around valve plate, and draining is unimpeded, can make overvoltage coal gas produce bigger moment again, closes valve plate rapidly, prevents overvoltage coal gas.Small and exquisite, the easy making of this device volume simultaneously, maintenance convenience, reliable performance, long service life.
