Abstract
The utility model provides a ball float over-voltage protector for a gaspipe network. The protector consists of a casing, a floating ball A connected with a floating ball cantilever, a valve core connected with the floating ball cantilever and a valve seat, a floating ball B in the casing, and a benchmark connected with the floating ball B, wherein the valve core and the valve seat are placed in a port of the casing, which is connected with a gaspipe network device, and are connected with the gaspipe network device through flanges. Compared with the prior art, the ball float over-voltage protector has the following advantages: firstly, gas leakage caused by the pressure fluctuation of the gaspipe network is avoided; secondly, gas leakage caused by the corrosion and gas blowby inside a drainer is avoided; thirdly, the gas leakage caused by water level depression in the drainer due to artificial water drainage is avoided; fourthly, gas leakage caused by evaporation of water and untimely water replenishing by managerial staff is avoided; and fifthly, the work intensity is relieved for the drainer managerial staff.
Description
Technical field
The utility model relates to a kind of gaspipe network float-ball type overvoltage protector.
Background technique
In the gas pipeline transportation service process, produce a large amount of dust-laden condensed waters, need in time to get rid of, in case reduce the circulation area of coal gas after retaining, even cause pipeline obstruction.Therefore be provided with a large amount of water seal hydathodes along gas-pipe line.
Existing hydathode, under the normal situation of operating mode, the leakage of energy effective seal coal gas when the operating mode instability, when abnormal conditions take place, will produce a large amount of unpredictalbe gas leakages when finishing drain function, cause serious accident:
1, when gaspipe network boosts unusually, gas pressure produces the gaspipe network overvoltage greater than water seal pressure, and coal gas will be broken through water seal, leak in a large number;
2, when hydathode dividing plate, discharge pipe during because of corrosion failure, design water seal pressure is lower than gas pressure, loses the water seal ability, and coal gas will leak in a large number;
3, do not understand operating mode person, open bottom blow-down valve and discharge water and wash one's hands etc., make the hydathode drawdown, the water seal ability reduces, and produces coal gas and leaks;
4, hydathode water evaporation is not attained the Way and is in time replenished, and the water seal ability drop produces coal gas and leaks.
Summary of the invention
The purpose of this utility model provides a kind of gaspipe network float-ball type overvoltage protector, and effectively control gaseous is leaked.
The technical solution of the utility model is: gaspipe network float-ball type overvoltage protector by housing, ball float A connect ball float cantilever, the spool that is connected with the ball float cantilever and valve seat thereof, ball float B and connected mark post in housing formed; Spool and valve seat place in housing and the port that the gaspipe network device is connected, are connected with the gaspipe network device by flange.
Gaspipe network float-ball type overvoltage protector of the present utility model has the following advantages compared with the prior art:
1, prevents that the gaspipe network pressure surge from producing gas leakage;
2, prevent the gas leakage that hydathode internal corrosion gas blowby causes;
3, prevent that the people from being draining, the gas leakage that the hydathode drawdown is taken place;
4, prevent water evaporation, administrative staff fail the gas leakage that timely moisturizing causes;
5, alleviate hydathode administrative staff's labor intensity.
Description of drawings
Fig. 1 is a gaspipe network float-ball type overvoltage protector structural representation of the present utility model;
Fig. 2 is that overvoltage protector of the present utility model is installed on the user mode schematic representation on the gaspipe network device.
Among the figure, 1-ball float A, 2-ball float cantilever, 3-spool, the 4-valve seat, 5-guide, 6-bearing pin, the 7-flange, 8-ball float B, 9-housing, the 10-mark post, 11-water sealed tank top board, 12-water sealed tank housing, 13-one Room water sealing (sealing water) pipe, 14-water seal base plate, 15-water-sealed clapboard, 16-stainless steel blowdown valve, 17-two, three water sealing (sealing water) pipes, 18-elbow.
Embodiment
As shown in Figure 1, gaspipe network float-ball type overvoltage protector of the present utility model by housing 9, ball float A connect ball float cantilever 2, the spool 3 that is connected with ball float cantilever 2 and valve seat 4 thereof, ball float B and connected mark post 10 in housing formed; Spool 3 and valve seat 4 place in housing 9 and the port that the gaspipe network device is connected, are connected with the gaspipe network device by flange 7.
Wherein, ball float A is connected with ball float cantilever 2 by bolt, and ball float cantilever 2 is connected with spool 3 by bearing pin 6, the bearing pin 3 outer guidees 5 that are provided with.Valve seat 4 is weldingly fixed on the housing 9.By table top supporting, mark post 10 1 ends pass housing lid by bolt to ball float B in housing 9.
Working principle:
When abnormal conditions take place, the water level of hydathode will take place obviously to reduce, and when the gaspipe network overvoltage, gas successively overcomes the water level discrepancy in elevation resistance of each hydroecium, enters the end closed chamber, and the water level of end closed chamber is descended rapidly.The utility model drives the power that ball float lifting simultaneously produces with SEA LEVEL VARIATION, and through the transmission of lever, the drive spool opens and pipe closes, and reaches the effect that coal gas is sealed.
