As the utility model discloses it is preferred, bolt and valve gap detachable threaded connection are passed through at discharge valve body top.
As the utility model discloses preferred, the discharge valve body is the structure that upper portion bore is greater than the lower part bore.
The utility model has the advantages that:
1. the exhaust holes of the traditional combined exhaust valve are arranged in a manner that the periphery of the top of the valve body is dispersedly arranged, and the opening of the exhaust pipe is controlled by the adjusting valve, so that the size of the exhaust holes can be adjusted according to actual working conditions to meet the actual use requirements, and unsmooth exhaust of the exhaust valve due to impurity blockage in the use process of the exhaust holes can be avoided;
2. through the arrangement of the drainage pipes, water flow carried by the combined exhaust valve during opening and closing actions can be guided to be drained to the drainage ditch, and leakage water generated due to sealing aging failure of the exhaust valve can be guided to the drainage ditch, so that the influence on the normal use of surrounding electrical elements and the corrosion of a water pipeline and a valve assembly can be avoided.
Drawings
The invention will be further explained with reference to the drawings:
fig. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the internal structure of the present invention;
in the figure, an exhaust valve body 1, a valve cover 2, a valve seat 3, a float bowl 4, a floating ball 5, an exhaust port 6, an adjusting valve 7, a drainage pipe 8, a movable joint 9 and a sealing ring 10.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, a combined type exhaust valve capable of adjusting air displacement and drainage comprises an exhaust valve body 1, a valve cover 2 is fixedly connected to the top of the exhaust valve body 1, a valve seat 3 is arranged at the bottom of the exhaust valve body 1, a floating barrel 4 is arranged in the exhaust valve body 1, a floating ball 5 capable of floating freely is arranged in the floating barrel 4, a vertical air outlet 6 is formed in the valve cover 2, and an adjusting valve 7 is fixedly mounted at the top of the air outlet 6.
Furthermore, the regulating valve 7 is an angle valve, and the outlet of the regulating valve 7 is connected with a drainage pipe 8 through a movable joint 9.
Further, the bottom of the exhaust port 6 is also provided with a sealing ring 10, and the sealing ring 10 and the floating ball 5 are matched to extrude and seal the exhaust port 6.
Further, a water inlet is also formed in the bottom of the buoy 4.
Further, the top of the exhaust valve body 1 is detachably connected with the valve cover 2 through bolts in a threaded manner.
Further, the exhaust valve body 1 is configured such that the upper caliber is larger than the lower caliber.
The working principle of the whole device is as follows:
when the device is used, when no water exists in the valve, the floating ball 5 is positioned at the bottom of the floating ball 4, when water is supplied to the pipeline again after the first time or the pipeline system is overhauled, a large amount of air in the pipeline can continuously flow to the high place, and the large amount of air is quickly discharged outwards through the air outlet 6, because the device is installed at the high place of the pipeline and is in an open state, when the pipeline is full of water, the water enters the air outlet valve, at the moment, the floating ball 5 rises under the action of the buoyancy force of the water, the air outlet 6 is closed by being extruded and sealed by the sealing ring 10, when a large amount of air is generated in the pipeline again, the air can enable the water surface in the cavity of the floating ball 4 to descend along with the water level, so as to open the air outlet 6, after the air is discharged, the water level rises, the water flow enters the floating ball 4 through the water inlet, the floating ball 5 also rises along with the water level, the air outlet 6 is closed by being extruded and sealed by being extruded by the sealing ring 10, thereby preventing the liquid from leaking out of the device, when the pipeline drains water, produce the negative pressure in the pipeline, the water level of the inner float bowl 4 of the valve drops rapidly, the float ball 5 falls back to the bottom of the float bowl 4, the outside air supplements the gas to the pipeline through the air release valve in the opposite order when exhausting, eliminate the negative pressure in the pipeline, prevent the pipeline from damaging because of producing the negative pressure, when the air release valve displacement is insufficient, increase the aperture of the damper valve 7, thus increase the exhaust speed of the air release valve, make the air release valve meet the working condition of actual use, when the displacement is too big, reduce the aperture of the damper valve 7, thus reduce the exhaust speed of the air release valve, in order to meet the working condition of actual use, the damper valve 7 is an angle valve in this apparatus, the outlet of the damper valve 7 connects with the drainage pipe 8 through the union 9, the air in the air release valve and rivers carried in the action process of exhausting and supplementing gas are discharged to the escape canal through the drainage pipe 8.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
