Description
Technical field
The utility model relates to a kind of gas leakage device that prevents, especially a kind ofly is applied to the full-automatic draining of iron and steel metallurgical industry gas pipeline hydathode and prevents the gas leakage device, belongs to coal gas and carries attached safety installation.
Background technique
At present, the built on stilts gas pipe line that lays of iron and steel enterprise all is equipped with hydathode.Its objective is the condensed water of under preventing the gas leakage state, getting rid of in the gas pipe line.The foundation of hydathode is the barometric pressure water-seal principle, and generally, the atmospheric pressure value in the gas pipe line is in safety range, and hydathode can proper functioning.But when the air pressure in the gas pipe line take place to increase and surpass the hydathode rating value, the water seal effect of hydathode will be lost efficacy, and showed as condensed water in the hydathode by excessive discharge, and to causing emptying, coal gas leaks thereupon.
In order to address this problem, the Patent equipment separately that please number be a plurality of patent SEPARATE APPLICATION such as 01239576.5 in the patent.Though they all produce effect,, they all exist defective.
1, they all can not prevent gas leakage fully.The precondition that above-mentioned Patent equipment works all is: the moment increase takes place suddenly in gas pipe line air pressure, and the increase value must be enough big.In view of the above, air pressure compressing condensed water sharply moves to the hydathode drain opening, forms water flow impact pressure, and water flow impact pressure starts the various devices that are installed in the hydathode drain opening and plays a role, and prevents gas leakage.
But, at gas pipe line air pressure gradually steadily under the increase state, the hydathode water displacement also shows as gradually steadily to be increased, after air pressure was increased to the hydathode rating value, condensed water will be drained, under this state, can not form rapid water flow impact pressure, they are difficult to start these devices without impact force, so all can not prevent gas leakage fully.
2, they all can not be opened automatically.When device recovered to open: the device that has was provided with man-operated mechanism, and the device that has can't be opened.Easily cause a large amount of ponding of gas pipe line and operational inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is: at the defective of said apparatus, a kind of hydathode gas leakage device that prevents is provided, this device can prevent gas leakage when gas pipe line air pressure acutely increases to the hydathode rating value suddenly, also can prevent gas leakage when gas pipe line air pressure steadily increases to the hydathode rating value gradually.This device can close automatically and open automatically.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of full-automatic draining and prevent the gas leakage device, comprise housing, the housing upper opening, the lower housing portion opening, opening is equipped with sends out orchid, it is characterized in that: the housing water intake is connected with the gas pipe line waste pipe, the housing drain opening is connected with hydathode, one lever is housed in the described housing, lever one end is ball float fixedly, the other end perforate dress pin, pin is connected on the lever pedestal and can rotates up and down around pin, the lever pedestal is fixed on the housing substrate, another pin is adorned in an inclined to one side end perforate in the middle of the lever, the pin below connects the round platform valve body that seal ring is housed, round platform valve body rotary motion trace below corresponding housing substrate drain opening, one ball float valve body is housed in the described housing, the ball float valve body is enclosed in by orifice plate, the housing waste pipe, Sealing, in the cavity that annulus constitutes, the ball float valve body can move up and down, corresponding waste pipe stage casing, below drain opening, and described orifice plate is connected on another housing substrate drain opening, it under the orifice plate housing waste pipe, housing waste pipe upper end is fixed on the housing substrate, and the intermediate portion clamping rings is installed Sealing on the annulus.
Above-mentioned full-automatic draining and prevent the coal leakage device, described ball float and described ball float valve body are hollow airtight, proportion is lighter than water, can make spheroid or cylindrical body or Rotary-table or cone or square body.
Working principle of the present utility model is: the condensed water in the gas pipe line is entered this full-automatic draining and is prevented the gas leakage device by the gas pipe line waste pipe, enters hydathode after the control of this device, is discharged by hydathode at last.Described control through this device is meant: make condensed water pass through, make coal gas not pass through.Concrete control measure are: two groups of valve mechanisms are set in the housing of described device: one group is the lever valve mechanism, comprise ball float, lever, pin, lever pedestal, pin, round platform valve body, seal ring, housing substrate drain opening, wherein, the buoyancy of ball float or action of gravity are in lever, lever drives round platform valve body and seal ring, with the pin on the lever pedestal is that round dot rotates up and down, and round platform valve body and seal ring rotary motion trace below corresponding housing substrate drain opening constitute the folding valve; Another group is a float valve mechanism, comprise ball float valve body, orifice plate, housing waste pipe, Sealing, annulus, waste pipe stage casing drain opening, wherein, the ball float valve body is closed in the cavity that can cross water that is made of orifice plate, housing waste pipe, Sealing, annulus, the ball float valve body can move up and down in cavity, corresponding waste pipe stage casing, ball float valve body below drain opening constitutes the folding valve.Two groups of valve mechanisms utilize the condensation buoyancy of water independently to open separately; Utilize the deadweight and the gas pressure of ball float or ball float valve body independently to close separately.Two groups of valve mechanisms cooperate can regulate water displacement, sets up the open force that the lever valve mechanism can improve valve.
Course of action of the present utility model is: in the time of in gas pipe line air pressure remains on the hydathode rating value, two groups of valve mechanisms utilize the floating function of condensed water independently to open separately, condensed water is discharged after entering hydathode by this device, and at this moment, the water seal effect of hydathode prevents gas leakage.
When gas pipe line air pressure surpasses the hydathode rating value, the condensed water that hydathode stores will reduce, and the horizontal plane of this device descends thereupon, and ball float and the utilization deadweight of ball float valve body and gas pressure are closed valve mechanism separately automatically, blocking-up coal gas enters hydathode, prevents that coal gas from leaking.
In the time of in gas pipe line air pressure returns to the hydathode rating value, the condensation buoyancy of water that newly imports this device is opened two groups of valve mechanisms automatically respectively, and hydathode recovers normal draining.
When gas pipe line air pressure remained on above the hydathode rating value for a long time, along with the increase or the minimizing of condensed water quantity, two groups of valve mechanisms all presented automatic unlatching respectively and close alternate cycles automatically, and hydathode presents the intermittent type draining.
The beneficial effects of the utility model are: one, both can when acutely increasing to the hydathode rating value suddenly, gas pipe line air pressure prevent gas leakage, also can when steadily increasing to the hydathode rating value gradually, gas pipe line air pressure prevent from gas leakage to have improved safety coefficient.Two, can close automatically and open automatically, when preventing gas leakage, do not influence the hydathode draining, avoided a large amount of ponding of gas pipe line, exempted the manual operation of opening device.
