Abstract
The utility model provides a natural gas water draining valve which is particularly suitable for the installation and the use in a collection, storage and transportation system of a natural gas mine. The utility model is composed of an upper valve chamber and a lower valve chamber formed by an upper valve body and a lower valve body which are provided with a guiding baffle, an inlet pipe and a natural gas discharging pipe are arranged on the upper part of the upper valve body, and a water discharging pipe is arranged on the lower valve body. The guiding baffle is provided with a set of through holes communicating the upper valve chamber with the lower valve chamber. A water discharging valve fixedly arranged on an inner wall of the lower valve body is communicated with the water discharging pipe. A floating cylinder penetrating the guiding baffle is hinged with a lever linked with the water discharging valve. The buoyancy difference of the floating cylinder formed by the density difference of gas and water media is used, when the floating cylinder is vertically lifted, the water discharging valve is pulled to be open or closed. The deposited water in a gas storing tank can be entirely discharged, and the natural gas leakage can be thoroughly eliminated.
Description
Technical field:
The utility model relates to the device of separate discharge connate water in the seal container of natural gas-storing, specifically a kind of rock gas drain valve.
Background technique:
Existing ZL012479594 patented technology exists rock gas gas to be sealed in the uuper valve chamber, can't realize the function of rock gas gas continuous hydrophobic.
The model utility content:
The utility model is to propose a kind of special messenger's of need not operation, the automatic hydrophobic choke of energy, non-consumes energy on the basis of existing technology, can drain the connate water in the gas holder automatically and guarantee that rock gas does not have the rock gas drain valve of a bit leakage.
The purpose of this utility model is achieved by the following technical solution:
It is to constitute uuper valve chamber and lower valve chamber by upper valve body that kicker baffle is installed and following valve body, on the top of upper valve body inlet tube and rock gas outlet pipe are installed, following valve body is equipped with waste pipe and deslagging plug, do one group of through hole at kicker baffle and be communicated with uuper valve chamber and lower valve chamber, fixing device is connected with waste pipe in the drain valve of following valve interior wall, the floating drum that is threaded onto kicker baffle is articulated in lever, the other end of lever is articulated in the valve rod of drain valve, inlet tube is connected in the waste pipe of the moisture trap of the waste pipe of rock gas gas holder or rock gas gas holder, connate water enters uuper valve chamber through inlet tube, one group of through hole through kicker baffle enters complete submergence floating drum in the lower valve chamber again, the rock gas gas of following connate water together to enter uuper valve chamber is closed in the top of uuper valve chamber, at this moment the floating drum that is set in kicker baffle is subjected to buoyancy of water bigger, floating drum vertically rises, the floating drum pull lever that rises is opened drain valve, by waste pipe connate water is discharged, decline along with water, the buoyancy that floating drum is subjected to reduces gradually, the floating drum that is set in kicker baffle vertically descends, promote lever and close drain valve, rock gas gas can be closed closely, can prevent natural gas leaking effectively, when the connate water in the rock gas gas holder enters in the uuper valve chamber once more, the rock gas that tightly is closed in the uuper valve chamber is discharged by outlet pipe, can thoroughly prevent natural gas leaking.
The utility model is compared with existing drain valve, has following advantage:
When keeping certain pressure in the container, the inlet tube gas-liquid was not advanced container when the inlet gas hydraulic coupling was less than or equal to container inner pressure; Can't realize hydrophobic function, the utility model has the rock gas outlet pipe can make container pressure be lower than the continuous draining choke function automatically of inlet pressure realization by the interior rock gas of timely amount discharge container.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The rock gas drain valve that the utility model proposes, it constitutes uuper valve chamber 9 and lower valve chamber 14 by upper valve body 2 and following valve body 3 that kicker baffle 11 is installed, on the top of upper valve body 2 inlet tube 1 is installed, rock gas steam outlet pipe 17 and baffle plate 6, following valve body 3 is equipped with waste pipe 12 and deslagging plug 5, kicker baffle 11 has been done one group of through hole 8 and has been communicated with uuper valve chamber 9 and lower valve chamber 14, fixing device is connected with waste pipe 12 in the drain valve 13 of following valve body 3 inwalls, the floating drum 7 that is threaded onto kicker baffle 11 is articulated in lever 15, the other end of lever 15 is articulated in the valve rod 16 of drain valve 13, place the cover 4 that turns in the lower valve chamber 14 to be fixedly connected on kicker baffle 11, turn to cover 4 sidewalls to do the short slot 10 that adapts to lever 15, turning to cover 4 can make the current turnover that enters lower valve chamber 14 straight down travel up to drain valve 13 discharges, the sand grains slag of carrying secretly with connate water is sunk in the bottom of following valve body 3, regularly discharge, can prevent that the sand grains slag from stopping up drain valve 13 by deslagging plug 5.It is work like this: the waste pipe that inlet tube 1 is connected in the moisture trap of rock gas gas holder, at this moment connate water enters uuper valve chamber 9 through inlet tube 1, one group of through hole 8 through kicker baffle 11 enters in the lower valve chamber 14 and complete submergence floating drum 7, the rock gas of following connate water together to enter uuper valve chamber 9 is closed in the top of uuper valve chamber 9, at this moment floating drum 7 is subjected to buoyancy of water bigger, floating drum 7 vertically rises, pull lever 15 is opened drain valve 13 drainings, decline along with water level, the buoyancy of floating drum 7 reduces gradually, floating drum 7 vertically descends, promote lever 15 and close drain valve 13, rock gas can be sealed closely and prevent natural gas leaking, in the time of in connate water enters valve pocket 9 once more, the rock gas gas in the uuper valve chamber 9 is discharged by rock gas outlet pipe 17, so repeatedly, utilize gas, the density difference of aqueous medium is poor to the buoyancy that floating drum 7 forms, pulling drain valve 13 opens or cuts out during floating drum 7 oscilaltions, reaches the connate water in the gas holder is all drained the automatic continous-stable operation of dehydration work.Can thoroughly stop the purpose of natural gas leaking again.
