Abstract
The utility model discloses an automatic exhaust valve. The automatic exhaust valve comprises a first shell, a second shell and a floating ball device, wherein the first shell is connected with the second shell in a threaded manner; a through hole is formed in the first shell; a first concave stage and a second concave stage are arranged inside the first shell; the floating ball device comprises a floating ball, a connecting rod connected with the floating ball, a boss arranged at the other end of the connecting rod, and a sealing gasket arranged on the end face of the boss; a flange is arranged on the end face of the first concave stage; the connecting rod is inserted into the boss; the flange is arranged between the floating ball and the boss; a ball valve is arranged at the bottom end of the second shell. The automatic exhaust valve is simple in structure and convenient to use, can exhaust air automatically, and can be used for preventing media inside pipelines from overflowing.
Description
Technical field
The utility model relates to a kind of outlet valve, relates in particular to a kind of automatic control pressure vent.
Background technique
Outlet valve is requisite device on pipeline, for getting rid of pipeline internal gas, but in the process of exhaust, because the medium liquid level in pipeline is higher than relief opening, will cause medium to flow out from outlet valve.In carrying out exhaust, just need to manually operate like this, open drain tap, see when having MEDIA FLOW out throttle down at once, such operation is very inconvenient, and can not be real-time carry out exhaust, cause operator's workload very large, wasting manpower and material resources.
Model utility content
The purpose of this utility model is: in order to address the above problem, provide a kind of automatic control pressure vent simple in structure, easy to use, it can automatic vent, and can prevent that the medium of pipe interior from overflowing.
To achieve these goals, the technical solution of the utility model is:
A kind of automatic control pressure vent, comprises the first housing, the second housing and floating ball device; Described the first housing and the second housing are threaded connection; In described the first housing, through hole is set; Described the first enclosure interior arranges the first concave station and the second concave station; Described floating ball device comprises ball float, connecting rod, the boss that is arranged on the described connecting rod the other end being connected with described ball float, the sealing gasket that is arranged on described raised head face; Described the first concave station end face is provided with flange; Described connecting rod is arranged in described flange; Described flange is arranged between described ball float and described boss; Described the second housing bottom is provided with ball valve.
Further, described flange is connected with described the first concave station by bolt.
Further, described flange is provided with some through holes.
Further, described floating ball device comprises nut, and described nut quantity is two.
Further, described ball float and connecting rod are threaded connection; Tapped hole on described ball float runs through whole spheroid.
The utility model is owing to having adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
The utility model is because the first housing and the second housing are threaded connection, can housing for convenience detach, maintain inner member; The utility model is due to floating ball device being set, and when medium liquid level exceedes certain altitude, sealing gasket will be floated to the second concave station end, and the relief opening on the first housing is blocked, and prevents that the medium of outlet valve housing inside from discharging from relief opening; The utility model is because ball float and connecting rod are threaded connection, and the tapped hole of ball float runs through whole spheroid, can need to regulate ball float height according to using, and uses to meet different occasions.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model automatic control pressure vent.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of automatic control pressure vent, comprises the first housing 1, the second housing 2 and floating ball device 3; Described the first housing 1 and the second housing 2 are threaded connection; The interior through hole 11 that arranges of described the first housing 1; Described the first housing 1 inside arranges the first concave station 12 and the second concave station 13; Described floating ball device 3 comprises ball float 31, connecting rod 32, the boss 33 that is arranged on described connecting rod 32 the other ends being connected with described ball float 31, the sealing gasket 34 that is arranged on described boss 33 end faces; Described the first concave station 12 end faces are provided with flange 4; Described connecting rod 32 is arranged in described flange 4; Described flange 4 is arranged between described ball float 31 and described boss 33; Described the second housing 2 bottoms are provided with ball valve 5; Because the first housing 1 and the second housing 2 are threaded connection, can valve body for convenience detach, maintain inner member; Owing to being provided with floating ball device 3, when medium liquid level exceedes certain altitude, sealing gasket 34 will be floated to the second concave station 13 ends, relief opening on the first housing is blocked, prevented that the medium of outlet valve housing inside from discharging from relief opening, owing in the second housing 2 bottoms, ball valve 5 being set, if need to maintain outlet valve inside, only need close ball valve 5, turn on the first housing 1, can operate.
Preferably, described flange 4 is connected with described the first concave station 12 by bolt.
Preferably, described flange 4 is provided with some through holes, can facilitate gas to discharge.
Preferably, described floating ball device 3 comprises nut 35, and described nut quantity is two, can lock ball float 31, prevents that long-time use from causing ball float 31 become flexible so that come off.
Preferably, described ball float 31 and connecting rod 32 are threaded connection; Tapped hole on described ball float 31 runs through whole spheroid; Can need to regulate ball float 31 height according to using, use to meet different occasions.
In sum, the utility model is simple in structure, easy to use, and it can automatic vent, and can prevent that the medium of pipe interior from overflowing.
