Abstract
The utility model discloses a vacuum pump shock absorption connecting pipe. The connecting pipe is connected between a secondary vacuum pump and a primary vacuum pump. The connecting pipe is composed of a top end straight pipe, a bottom end straight pipe and a middle pipe located between the top end straight pipe and the bottom end straight pipe. The top end straight pipe is connected with the secondary vacuum pump, the bottom end straight pipe is connected with the primary vacuum pump, and the middle pipe is arranged to be U-shaped. The vertical section of the middle pipe is in a U-shaped structure, so in the working process of the device, strenuous vibration which is transmitted from a middle vacuum pump and a bottom vacuum pump to the connecting pipe can be effectively relieved, the connecting pipe can be effectively protected, damage of the connecting pipe in the strenuous vibration is prevented, and service life is long.
Description
Technical field
The utility model belongs to the chemical machinery technical field, is specifically related to a kind of vacuum pump damping connecting tube.
Background technique
At present, need use the negative pressure device of three grades of vacuum pump serial connections in the manufacturing mechanism of thioglycolic acid, present three grades of vacuum pumps generally adopt straight tube that the three is connected in series each other.Self comparatively violent vibrations can take place during vacuum pump work, especially in the device start process, two-stage vacuum pump and the vibrations of one-level vacuum pump are more very.Three grades of vacuum pumps and two-stage vacuum pump adopt straight tube is connected still can, but two-stage vacuum pump also adopts straight tube with being connected of one-level vacuum pump, vacuum pump connecting tube therebetween is easy to damage, influences the normal operation of equipment, causes the reduction of manufacturing efficiency.
Summary of the invention
To the deficiency that existing technology exists, the utility model technical problem to be solved is, provide a kind of simple and reliable for structure, effectively protect connecting tube to prevent the vacuum pump damping connecting tube that damages.
For solving the problems of the technologies described above; The technological scheme that the utility model is taked is: a kind of vacuum pump damping connecting tube; Said connecting tube is connected between two-stage vacuum pump and the one-level vacuum pump, its by top straight tube, bottom straight tube and between intervalve constitute, said top straight tube connects two-stage vacuum pump; Said bottom straight tube connects the one-level vacuum pump, and said intervalve is set to U-shaped.
Above-mentioned vacuum pump damping connecting tube, said intervalve is provided with control valve.
The advantage of the utility model vacuum pump damping connecting tube is: it is U type structure that intervalve is provided with the longitudinal section; Equipment in the course of the work; Can effectively alleviate the strenuous vibration that two-stage vacuum pump and one-level vacuum pump pass to connecting tube; Effectively the protection connecting tube prevents that connecting tube from damaging, long service life in strenuous vibration.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
The vacuum pump damping connecting tube 1 of the utility model uses in the negative pressure device of three grades of vacuum pumps serial connections, and is as shown in Figure 1, and employing straight tube 5 is connected between three grades of vacuum pumps 4 and the two-stage vacuum pump 2.Vacuum pump damping connecting tube 1 is connected between two-stage vacuum pump 2 and the one-level vacuum pump 3; It is made up of with the intervalve 13 of bottom straight tube 12 top straight tube 11, bottom straight tube 12 and connection top straight tube 11; Wherein, Top straight tube 11 connects two-stage vacuum pump 2, and bottom straight tube 12 connects one-level vacuum pump 3, and intervalve 13 is set to the U-shaped structure.For ease of control and convenient maintenance, on intervalve 13, be provided with control valve 6 to vacuum pump damping connecting tube 1.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
