The utility model provides a temperature and pressure reduction device vibrations and noise big, steam and the required distance of desuperheating water complete mixing are long, the accurate problem of adjusting, controlling difficulty of temperature and pressure reduction.
Description
Technical Field
The utility model belongs to the technical field of high temperature steam's temperature and pressure reduction technique and specifically relates to a split type temperature and pressure reduction device.
Background
Various high-temperature and high-pressure steam produced by enterprises such as thermoelectricity and chemical engineering can be supplied to subsequent processes for use only by reducing temperature and pressure. At present, a temperature and pressure reducing device generally adopts a structural design (pressure reducing-temperature reducing structure) of reducing pressure and then reducing temperature. The structure has larger vibration and noise due to less decompression stages and large decompression stage difference; the temperature-reducing water sprayed by the water spraying device is difficult to mix with the steam and the temperature-reducing water due to the conditions, the flow speed and other factors of the steam, the working distance is too long, the temperature and the pressure cannot be adjusted, and the steam in an ideal state is difficult to obtain.
Disclosure of Invention
To exist not enough among the prior art, the utility model provides a split type temperature and pressure reduction device solves above-mentioned vibrations and noise big on the large side, the operating distance is long, the unable accurate control of temperature and pressure, the unsatisfactory problem of temperature and pressure reduction effect, carries out multistage temperature and pressure reduction through adopting cage, decompression mixed silencing device and orifice plate for reach the effect of ideal temperature and pressure reduction with shorter operating distance. The utility model adopts the technical proposal that:
the utility model provides a split type temperature and pressure reduction device, includes cage in the valve body, mixes silencing device and orifice plate, its characterized in that of decompressing:
the cage, the pressure reducing mixing silencer and the transition connecting pipe are sequentially arranged in the closed split type temperature and pressure reducing device.
The cage is arranged between the valve cover and the valve seat. And a pressure and flow regulating device is also arranged in the cage. The pressure and flow regulating device is a valve rod core component and can move up and down in the cage. The pressure reducing mixing silencer is provided with a plurality of orifices. The decompression mixing silencer is fixed in the mounting seat.
More preferably, the pressure reducing mixing muffler is provided with a water spray device. And a throttling orifice plate is arranged in the transition connecting pipe. The orifice plate is welded in the transition pipe, and a plurality of orifices are arranged on the orifice plate. The decompression mixing silencer and the orifice plate can be arranged in multiple stages.
The utility model has the advantages that: when high-temperature and high-pressure steam passes through the device, the cage, the pressure reduction mixing silencer and the throttling orifice plate are utilized to complete the pressure reduction-temperature reduction-pressure reduction process, and finally the steam enters the steam pipeline at the outlet, so that the efficiency is higher than that in a simple pressure reduction-temperature reduction process, and the vibration and the noise are lower. The pressure and flow regulating device arranged in the cage can also regulate the flow of the steam passing through according to the requirement. The arranged water spraying device achieves the aim of temperature reduction.
