Description
Technical field
The invention belongs to vacuum pump technology field, anti-down water suction device before being specifically related to a kind of vacuum pump.
Background technique
Vacuum pump is oil, chemical industry, medicine, food, a kind of equipment generally used in the industry industrial production such as chemical fibre, utilize machinery, physics, the methods such as chemistry are bled to container, to obtain and to maintain the device of vacuum, this wherein all mechanical pump of most of vacuum pump be to intake, when operate miss can cause vacuum to be often with water or check often occurring not in time to intake in vacuum pump, when vacuumizing, inside can produce negative pressure, if at this moment first powered-down, rear closedown vacuum valve, so in powered-down this time difference with closedown vacuum valve, external pressure can force water in vacuum pump or oil substances suck-back, as Timeliness coverage of intaking, then termination of pumping cleaning impact is produced, serious meeting causes equipment accident.
Summary of the invention
For solving the problem, anti-down water suction device before the invention discloses a kind of vacuum pump, can effectively solve suck-back water problem, and can avoid because operate miss or inspection occur to intake in vacuum pump not in time, structure is simple, and easy to use, safety, increases work efficiency.
For achieving the above object, technological scheme of the present invention is as follows:
Anti-down water suction device before a kind of vacuum pump, it is characterized in that: comprise vacuum buffer tank, vacuum adapter is provided with above described vacuum buffer tank, bleeding point is provided with above described vacuum adapter, sliding positioning sleeve is provided with in vacuum adapter, ball lever is arranged in sliding positioning sleeve and can moves up and down, adjustable positioning rod is provided with above ball lever, extend to below ball lever in vacuum buffer tank, closure plate and ball float is provided with below ball lever, described closure plate is arranged between ball float and the lower end of vacuum adapter, and the diameter of closure plate is greater than the diameter of vacuum adapter.
As a modification of the present invention, the surface of contact of described closure plate and vacuum adapter is provided with teflon gasket.
The invention has the beneficial effects as follows:
Anti-down water suction device before a kind of vacuum pump of the present invention, ball float and closure plate are set, when water level rise and exceed reach ball float position time, ball float rise, closure plate seals vacuum adapter simultaneously, such water would not bring vacuum pump into, can effectively solve suck-back water problem, can avoid because operate miss or inspection occur to intake in vacuum pump not in time, structure is simple, easy to use, safety, working efficiency improves.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numerals list:
1, vacuum buffer tank, 2, bleeding point, 3, adjustable positioning rod, 4, vacuum adapter, 5, sliding positioning sleeve, 6, closure plate, 7, ball lever, 8, ball float, 9, teflon gasket.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, following embodiment should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
As shown in the figure, anti-down water suction device before a kind of vacuum pump of the present invention, comprise vacuum buffer tank 1, vacuum adapter 4 is provided with above described vacuum buffer tank 1, bleeding point 2 is provided with above described vacuum adapter 4, sliding positioning sleeve 5 is provided with in vacuum adapter 4, ball lever 7 is arranged in sliding positioning sleeve 5 and can moves up and down, adjustable positioning rod 3 is provided with above ball lever 7, extend in vacuum buffer tank 1 below ball lever 7, closure plate 6 and ball float 7 is provided with below ball lever 7, described closure plate 6 is arranged between the lower end of ball float 7 and vacuum adapter 4, the diameter of closure plate 6 is greater than the diameter of vacuum adapter 4.
During work, ball lever 7 does vertical motion in sliding positioning sleeve 5, vacuum pump in use, outwards bled by vacuum adapter 4, when vacuum buffer tank 1 internal cause misoperation water level rise and exceed reach ball float 8 position time, ball float 8 can be driven to rise along making sliding positioning sleeve 5, and closure plate 6 is sealed the lower end of vacuum adapter 4, such water would not bring vacuum pump into simultaneously; When after draining, ball float 8 declines along making sliding positioning sleeve 5, and closure plate 6 leaves the lower end of vacuum adapter 4, when adjustable location 3 is blocked on upper sliding positioning sleeve 5, vacuum buffer tank 1 drops into and continues to use, and anti-down water suction device before pump of the present invention, arranges ball float 8 and closure plate 6, can effectively solve suck-back water problem, can avoid because operate miss or inspection occur to intake in vacuum pump not in time, structure is simple, easy to use, safety, working efficiency improves.
The present invention is provided with teflon gasket 9 at described closure plate 6 with the surface of contact of vacuum adapter 4, corrosion-resistant, and when closure plate 6 contacts with vacuum adapter 4, plays seal action.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned mode of execution, also comprises the technological scheme be made up of above technical characteristics combination in any.
