Description
Technical field
The utility model belongs to petroleum machinery field, relates to a kind of floating ball lever self-closing device.
Background technique
Multi-purpose station and terminal have gas-fired heater, once terminal separator and multi-purpose station oil expeller liquid level height can cause natural gas line oil-filled, can cause gas-fired heater, terminal to the outer gas transmission line of multi-purpose station, multi-purpose station to the oil-filled accident of purifying device for natural gas pipeline, can cause outer Trunk-line frozen block phenomenon winter, the serious accidents such as heating plant of burning cause heavy losses simultaneously.Therefore, need to design a kind of device to overcome the problems referred to above.
Summary of the invention
The purpose of this utility model is to provide a kind of floating ball lever self-closing device, solves natural gas line due to the oil-filled problem easily causing the accident.
The utility model is achieved through the following technical solutions: floating ball lever self-closing device, comprise tank body and inner ball float shutoff device, and on described tank body, upper cover is housed, tank body both sides entrance point and outlet end are equipped with respectively suction flange and outlet(discharge) flange; Described ball float shutoff device comprises ball float, connecting rod, L-type plate, valve gap and valve seat, wherein, valve seat is contained in the entrance point of tank body, on valve seat, there is valve gap, L-type plate one end and valve gap welding, the other end connects ball float by connecting rod, between the flex point of L-type plate and valve seat, is provided with rotating shaft, and ball float bottom can contact with tank body bottom surface.
Further, inside described tank body, outlet end is also equipped with frog suppression network.
Further, described tank base is equipped with blowdown valve.
Further, the outlet end of described tank body is also equipped with pressure transmitter.
Adopt the good effect of technique scheme: the utility model is in the time that multi-purpose station uses, be arranged on the outlet port of oil expeller, the principle of application buoyancy, throttle down, has also ensured oven when having ensured outer gas transmission in time, there will not be frozen block phenomenon and the generation of burning the accidents such as firing sector, effectively solve natural gas line due to the oil-filled problem easily causing the accident, on-the-spot application is very good, have safe and reliable, simple operation and other advantages.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 tank body, 2 upper covers, 3 suction flanges, 4 outlet(discharge) flanges, 5 ball floats, 6 connecting rods, 7 L-type plates, 8 valve gaps, 9 valve seats, 10 frog suppression networks, 11 blowdown valves, 12 pressure transmitters.
Embodiment
below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is structural representation of the present utility model, as shown in the figure, floating ball lever self-closing device, comprise tank body 1 and inner ball float shutoff device, on described tank body 1, upper cover 2 is housed, tank body both sides entrance point and outlet end are equipped with respectively suction flange 3 and outlet(discharge) flange 4, are respectively used to be connected with the pipeline at two ends.Described ball float shutoff device comprises ball float 5, connecting rod 6, L-type plate 7, valve gap 8 and valve seat 9, wherein, valve seat 9 is contained in the entrance point of tank body 1, on valve seat 9, there is valve gap 8, L-type plate 7 one end and valve gap 8 weld, the other end connects ball float 5 by connecting rod 6, between the flex point of L-type plate 7 and valve seat 9, is provided with rotating shaft, and ball float 5 bottoms can contact with tank body 1 bottom surface.Whether ball float has fluid for perception tank interior, when thering is no oil-feed in tank body, due to the Action of Gravity Field of ball float, open by connecting rod, the moving valve gap of L-type strip, once gas mixture enters tank interior, will make ball float float, affect connecting rod, and then close valve gap by L-type plate.
For the gas mixture to tank interior filters, allow gas pass through smoothly, described tank body 1 inner side outlet end is also equipped with frog suppression network 10, and some oil slick can hang on frog suppression network, prevent oil-feed in export pipeline.
In order to discharge in time the fluid that enters tank interior, blowdown valve 11 is equipped with in described tank body 1 bottom.
The outlet end of described tank body 1 is also equipped with pressure transmitter 12, because after valve gap is closed, can cause the pressure of tank interior to raise, pressure transmitter can detect pressure and warning in time, remind operator on duty, operator on duty takes appropriate measures immediately, prevents the generation of production accident.
When use, by suction flange and the outlet(discharge) flange connecting line respectively of tank body both sides, now, valve gap is under the Action of Gravity Field of ball float, and in the state of opening, rock gas enters tank body smoothly, then exports by export pipeline.Once occur oil-filled phenomenon, gas mixture enters tank body, run up to after certain altitude, ball float slowly floats, affect connecting rod, and then close valve gap by L-type plate, the pressure in tank body raises, after pressure transmitter perception, report to the police, remind operator on duty, operator on duty takes appropriate measures immediately.The on-the-spot application of this device is very good, have safe and reliable, simple operation and other advantages.
