Abstract
The utility model belongs to drainage facilities of gas pipeline, especially drain equipment over pressure protector, which can prevent the drain equipment gas leak and drain equipment water volatilization due to gas over pressure. The drain equipment over pressure protector consists of anti-leaking device and anti-volatilization device. The anti-leaking device consists of annular blocking plate, supporting frame, valve cover, sealing ring and water inlet duct in the drainage pipe. The anti-volatilization consists of anti-volatilization water inlet duct, annular water outlet plate, sign post, floating ball, baffle plate, head cover, head cover flange, drainage hole in the diaphragm, water duct and water outlet. Hand hole, hand hole flange and hand hole blanking plate are under the drainage pipe of the drainer. When the over-pressure gas pushes the valve cover, the water duct is blocked so that the gas leaking is prevented. When there is lack of water, the floating ball blocks the water outlet of the annular water outlet plate to prevent the water volatilization. The sealing surface of this device will not maintain fouling and slag so that a good sealing effect is achieved. This device, which is strong in preventing over-pressure of the gas and has small volume, is convenient to install and maintain and has long service life.
Description
Technical field
The utility model belongs to gas pipe line drainage field, and particularly a kind of hydathode overvoltage protector is used for the device of effectively preventing the coal gas overvoltage to cause hydathode gas leakage and preventing the volatilization of hydathode moisture content.
Background technique
In gas pipeline, ponding and dirty slag can appear inevitably, emit with hydathode, but gas pressure can not surpass hydathode water seal height H, otherwise coal gas will leak in a large number.Because the gaspipe network pressure surge is bigger, exceed water seal pressure, cause coal gas overvoltage phenomenon to happen occasionally, the hydathode that also has is owing to reasons such as unreasonable structure cause the moisture content volatilization, thereby cause water seal height to descend, cause coal gas overvoltage phenomenon and cause a large amount of gas leakages, overvoltage causes the hydathode water seal to puncture, and causes the serious accident of gas leakage directly to threaten production, equipment and personal safety again.
Once had and a kind ofly it is said that can solve uprushes because of gas pressure and exceed the device that water seal pressure makes the gas leakage problem, but this device movable piece is many, blocking part is many, leakage area is big, can not bear the pressure recurrent fluctuations, dirty slag in the ponding is the difficulty that is difficult to overcome to the destruction of its sealability, easily card is stifled, therefore leakage gas in a large number still.Also fail to solve simultaneously because the overvoltage phenomenon that the volatilization of hydathode moisture content is caused.
Summary of the invention
The purpose of this utility model provides a kind of device that prevents coal gas overvoltage leakage and moisture content volatilization, hydathode overvoltage protector.
The purpose of this utility model realizes by following technical proposals.
According to hydathode overvoltage protector of the present utility model; it is characterized in that being connected into by leaking preventing device that stops the coal gas overvoltage to be leaked and the volatilization prevention device that prevents the moisture content volatilization; described leaking preventing device is by the annular closure plate in the waste pipe that is located at hydathode; be fixed on the carriage on this annular closure plate top; be sleeved on the valve gap on this carriage; be fixed on the seal ring on this valve gap and be located at the middle water inlet short tube of annular closure plate and form; the position of seal ring is corresponding with water inlet short tube inlet; described volatilization prevention device is by the water outlet standpipe that is connected with the waste pipe of hydathode; be contained in the annular water outlet plate of this water outlet standpipe lower end; place the eyelet of this annular water outlet plate and the mark post that has level scale among the eyelet on the water outlet standpipe top cover; be fixed on the ball float of this mark post top near the close annular oriffice upside of baffle plate and mark post bottom of top cover downside; the top cover flange of top cover downside; weep hole on the water outlet standpipe dividing plate, the aqueduct that is connected of weep hole is formed therewith.
The plate face of described annular closure plate and waste pipe axis angle are 45-90 °, and the angle of the axis of described waste pipe 1 and the axis of hydathode is 0 °-90 °.
The diameter of described baffle plate is greater than the eye diameter of top cover, the ultimate range between baffle plate and the top cover less than the weep hole lower edge to the ultimate range between the ball float end face.
Described floating ball diameter is greater than the aperture of annular water outlet plate.
Described aqueduct lower end is provided with drain opening, and this drain opening is connected with sewerage.
The lower end of described water outlet standpipe is provided with lower shoe, and the place is provided with hand hole at the corresponding valve gap of waste pipe downside, and the hand hole lower end is provided with hand hole flange and hand hole closure plate.
Described valve gap and carriage rotate and are slidingly matched.
Compared with prior art, the utlity model has following characteristics:
1, leak-stopping device: when hydathode bears normal gas pressure, the water of hydathode is by valve gap in waste pipe and the utility model and the gap below the waste pipe, intake short tube, water outlet standpipe, annular water outlet plate, make that ball float floats, mark post rises, baffle plate on the mark post blocks the top cover eyelet, mark post demonstrates high water level, water flows into aqueduct and drain opening from the weep hole on the dividing plate, flows into sewerage at last.When the gas pressure overvoltage, water and coal gas that hydathode is a large amount of rush at valve gap, and valve gap is sealed into water short tube along movement of bracket tightly in the effect lower seal of high pressure, thereby has prevented the leakage of water and coal gas effectively, plays the effect of leak-stopping device.
2, waterproof volatilizer: when the normal draining of hydathode or a large amount of draining, ball float holds up mark post, show high water level, when the water in the hydathode lacked because of volatilization or other reasons, ball float drove mark post and falls after rise, and ball float is fallen on the annular water outlet plate, cover water outlet, hydathode all is hedged off from the outer world together with the water in the leaking preventing device, thereby makes water stop volatilization, stopped the generation of the hydathode overvoltage phenomenon that causes because of water volatilization.
The outstanding advantage of this device is: only have one capable of blocking, and for rotating the combination of sliding, can tightly block the leakage of coal gas fast, the blocking-up point is one, and the blocking-up area is little, and because blocking-up face is vertical or downward plane, can not deposit dirty slag, thereby guarantee the leakproofness blocked, the compression resistance fluctuating nature is good, and seal ring is not fragile.Because the volatilization prevention device can prevent the moisture content volatilization by efficiently and effectively, thereby has stopped because the generation of the coal gas overvoltage phenomenon that the water volatilization causes.The utility model can also improve the water seal height of hydathode in addition; Accurately show the hydathode height of water level; Can do the filler uses.
It is little, simple in structure that this device has a volume, makes easily, carries out installation and maintenance by hand hole, very convenient, long service life, reliable performance.
