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.

As shown in fig. 1, the embodiment of the utility model provides a split type temperature and pressure reduction device, including cage 2 in the valve body 5, water jet equipment 6, the mixed silencing device 8 of decompression, orifice plate 10, cage 2, water jet equipment 6, the mixed silencing device 8 of decompression and orifice plate 10 set gradually in the split type temperature and pressure reduction device of confined to realize decompression-temperature reduction-decompression's multistage step.
Cage 2 sets up between valve gap 1 and disk seat 4, and valve gap 1 plays the effect of compressing tightly, and disk seat 4 holds cage 2 and plays stabilizing effect, also makes cage 2 also convenient to detach and maintenance simultaneously.
Still be provided with pressure and flow control device in the cage 2, for valve stem core subassembly 3, can reciprocate in cage 2 to adjust the throttle window, the flow that control steam passes through.
The decompression mixing silencer device 8 is provided with a plurality of throttling holes and fixed in the mounting seat 7, and vibration and noise during steam passing are reduced.
Decompression mixing silencing device 8 is provided with water jet equipment 6, and when steam passed through, water jet equipment 6 blowout desuperheating water mixes with steam, reaches better cooling effect.
A throttling orifice plate 10 is arranged in the transition connecting pipe 9 and welded in the transition connecting pipe, a plurality of throttling orifices are arranged on the throttling orifice plate 10, when steam passes through the throttling orifice plate 10, the pressure is reduced again, and finally the steam enters a steam pipeline 11 at an outlet.
More preferably, decompression mixing silencing device 8 and orifice plate 10 all can multistage setting, namely in the rear end of this device, can install several decompression mixing silencing device 8 and orifice plate 10 additional, have increased the progression of reducing the temperature and reducing the pressure, make the efficiency of reducing the temperature and reducing the pressure higher.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
