Abstract
The utility model relates to a high sensitivity drainage device over-pressure protection device, which is additionally provided with a sensitivity adjuster and a gas-water separator at the front of the original over-pressure protection device. The sensitivity adjuster can completely eliminate the drainage device over-pressure protection device or a drainage device coal gas leakage prevention device and prevents an over-pressure dead area of coal gas leakage, and can cut off over-pressure leak coal gas fast, accurately and tightly when coal gas pressure is larger than all area of actual water lute pressure of a drainage device; the gas-water separator can completely overcome the phenomenon that the drainage device over-pressure protection device or the drainage device coal gas leakage avoiding device is automatically closed because of a large number of drainage of the drainage device and causes blocking drainage. The sensitivity adjuster is a U-shaped water lute cavity body composed of an upper inlet pipe, a lower inlet pipe, a hand hole, a lower outlet pipe, an upper outlet pipe, and the like; the gas-water separator is a device body composed of a guide pipe and a diversion pipe. The high sensitivity drainage device over-pressure protection device does not have any power and has automatic recognition, and drains water when water exists and is closed when coal gas exists, and has the advantages of smart device, convenient installation and maintenance and long service life.
Description
Technical field
The utility model 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 (this moment gas pressure and the difference of water seal pressure be called the overvoltage protection dead band) time; this device can not cut off the coal gas that leaks immediately; have 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 prior art exists; the purpose of this utility model provides a kind of excess voltage protector for high sensitivity drainer; this device is by 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 achieving the above object, the utility model is achieved through the following technical solutions:
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 successively by upper inlet pipe, lower inlet pipe, following outer pipe, upper outlet pipe, 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 by skirt and its axis of honeycomb duct.
The height h of described sensitivity regulator dividing plate is 150-3000mm; Axis angle α between described moisture trap skirt and the honeycomb duct is 90 °-270 °; On described 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 beneficial effects of the utility model are:
1, be provided with sensitivity regulator, can make overvoltage coal gas dead band is zero.When the normal draining of hydathode, sewage by 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 exports by hydathode; flow into the upper inlet pipe of sensitivity regulator; overvoltage coal gas obtains savings in its lower inlet pipe; along with gas pressure increases; liquid level is pressed to the lower end; before liquid level arrives 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 overvoltage coal gas punctured ponding wherein in following outer pipe bottom moment, and it is by outer pipe down; upper outlet pipe and moisture trap; 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 be not related to close valve plate.Its working procedure is: when the normal draining of hydathode, sewage flows into the moisture trap skirt by 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 flow 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, and overvoltage coal gas can be tightly prevented in zero dead band, and draining in a large number is 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.
