Problems solved by technology

[0002] In the prior art, the dissolved air release device has a pressure reducing valve or a dissolved air release device, and the dissolved air water is released into the air flotation tank through the pressure reducing valve or the release device, which is relatively complicated in terms of manufacturing process and operability. The water release effect is not very ideal, it is easy to block, and the manufacturing cost is also high

Abstract

The invention discloses an external placed releasing device achieving instantaneous pressure-reducing, and relates to the technical field of waste water treatment. A guide pipe inlet is mounted in the middle of the lower end of a lower valve seat , a guide pipe outlet is mounted in the middle of a releasing barrel body, and valve seats are mounted at the two ends of the releasing barrel body through bolts correspondingly; and a valve rod is connected with the middle of the upper valve seat in a penetrating mode, a valve plate is mounted at the lower end of the valve rod, an adjusting hand wheel is mounted at the upper end of the valve rod, fastening nuts are mounted on the valve rod, and the fastening nuts are connected to the upper valve seat in a fastening mode. According to the external placed releasing device achieving instantaneous pressure-reducing, the purification rate is increased greatly, so that the processing ability of whole equipment is promoted, the cost is lowered, the power of a reflux pump is lowered, and the energy-saving effect is obvious.

Description

Technical field [0001] The invention relates to an external instantaneous decompression release device, belonging to the technical field of sewage treatment. Background technique [0002] In the prior art, the dissolved gas release device has a pressure reducing valve release or a dissolved gas release device, and the dissolved gas water is released into the air flotation tank through the pressure reducing valve or the release device. This is relatively complicated in the production process including the operability. The water release effect is not ideal, it is easy to block, and the manufacturing cost is also high. Summary of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide an external instantaneous pressure relief release device. [0004] An external instantaneous decompression release device of the present invention, which comprises a draft tube inlet, a valve seat, a valve plate, a valve stem, a draf...
