Abstract
The utility model relates to a lever ball-floating valve type drain valve, comprising a shell (16), a floating barrel (8), a connecting rod (6), a valve lifting rod (9), a water delivery pipe (7), a ball-shaped water outlet valve clack (10), a ball-shaped check valve ball (3), etc. The valve lifting rod (9) is connected to the middle part of the connecting rod (6) and is suspended in the floating barrel (8). Greater lifting force can be provided for the valve lifting rod (9) needing minor floating force of the floating barrel, and the ball-shaped water outlet valve clack (10) is driven to switch off a valve and make water flow out; accordingly, the volume of the drain valve is reduced, the weight is lightened, and the drain valve has favorable working property. The utility model is suitable for various industrial steam heating systems.
Description
The utility model relates to a kind of drain valve, a kind of improved lever keg float ball-valve type drain valve.
Drain valve is the important component part of industrial enterprise's steam-heating system, is used for automatically, the water of condensation in the releasing system promptly, stops steam leakage, improves device heat efficiency.Existing Open bucket steam trap (referring to Fig. 3), form by housing (16), keg float (8), water outlet flap (10) etc., pressure when this drain valve is closed is provided by the buoyancy of keg float (8) fully, because water outlet flap (10) directly is connected on the keg float (8), keg float (8) must have enough big volume, could guarantee the pressure of water outlet flap (10) closed condition, the volume of drain valve is inevitable bigger like this, it is also big to take up room during installation, make pipe-line system be not easy to reach rational layout, carrying is also inconvenient.
It is little, in light weight that the purpose of this utility model provides a kind of volume, the lever keg float ball-valve type drain valve of reliable performance.
The technical solution of the utility model is: a connecting rod is set in hydrophobic valve housing, one end of connecting rod housing, the other end keg float, the middle part poppet-valve bar that is connected through the hinge that is connected through the hinge that is connected through the hinge, the poppet-valve bar is hollow shape, there is base plate its upper end for uncovered, lower end, be suspended in the keg float, conduit pipe one end is communicated with water outlet, the other end inserts in the poppet-valve bar, and spherical water outlet flap is arranged on the below of conduit pipe lower end mouth.
The utility model only needs less keg float buoyancy to provide the bigger power that lifts to the poppet-valve bar, promotes spherical water outlet flap and closes water outlet.Can reduce the keg float volume like this, thereby reduce the volume of drain valve, also corresponding the alleviating of weight of while drain valve, and can make the outlet valve lobe have excellent sealing performance, in addition, conduit pipe is long and bore is thinner, has good water delivery gas barrier property.
Other purposes of the present utility model and advantage can be by showing significantly in the following drawings and Examples.
Fig. 1 is a kind of concrete structural representation that the utility model is implemented.
Fig. 2 is the structural representation of poppet-valve bar among Fig. 1.
Fig. 3 is the structural representation of existing Open bucket steam trap.
Among the figure, 1, adjusting screw; 2, water outlet; 3, check valve ball; 4, water intake; 5, hanger; 6, connecting rod; 7, conduit pipe; 8, keg float; 9, poppet-valve bar; 10, water outlet flap; 11, supporting base; 12, hinge; 13, tube; 14, aperture; 15, hinging hole; 16, housing.
Embodiment:
(referring to Fig. 1) the utility model is by housing (16), keg float (8), water outlet flap (10), connecting rod (6), poppet-valve bar (9), conduit pipe compositions such as (7), one end of connecting rod (6) is by hinge (12), hanger (5) connects housing (16), the other end connects keg float (8) by hinge (12), poppet-valve bar (9) upper end is connected the middle part of connecting rod (6) by hinge (12), and be suspended in the keg float (9), for the ease of processing and fabricating, poppet-valve bar (9) can be by the formations (referring to Fig. 2) such as supporting base (11) of tube (13) and lower end, between conduit pipe (7) and the tube (13) certain interval should be arranged, passage as current, in order to make drain valve have certain venting quality, on the tube (13) of poppet-valve bar (9) some apertures (14) can be set, supporting base (11) is provided with some apertures (14) that are used for draining, in order to make outlet valve lobe (10) that good alignment be arranged, wear resistance, good closing property, water outlet flap (10) is spherical.In order to prevent the refluence of condensed water, the top of conduit pipe (7) upper end-hole is provided with spherical check valve ball (3).
