Abstract
The utility model belongs to a device for flushing a flange type differential-pressure pressure transmitter in a fluid pressure inspection system, and especially relates to a device for flushing a flange type differential-pressure pressure transmitter, comprising a sampling valve connected on an outlet pipe of a technical container; wherein the sampling valve is connected with the flange type differential-pressure pressure transmitter through a flange, a flushing ring is arranged between the sampling valve and the flange connected with the flange type differential-pressure pressure transmitter through a sealing gasket; the flushing ring has a structure characterized in that a cylindrical wall of a circular ring is radially provided with two symmetrical flushing holes, the flushing holes are provided with internal screw threads, one of the flushing holes is connected with a flushing pipe equipped with a valve through the screw thread. The device of the utility model can conveniently clean accumulation in front of an isolation diaphragm of the flange type differential-pressure pressure transmitter, and quickly and regularly flush a pressure detection loop, thereby ensuring data reliability of a pressure detection system; in addition, the device can reduce workload of maintainers, thereby improving labor condition.
Description
Technical field
The utility model belongs to the device of flushing flange form differential pressure pressure unit in the fluid pressure check system, particularly a kind of flange form differential pressure pressure unit flusher.
Background technology
The coking chemical system has many fluid pressure inspection instrument: pressure-type liquidometer.This liquid level gauge is one of most widely used metering system in the level gauging; When in the container liquid being housed, because gravitate can produce static pressure to the bottom and the sidewall of container; When density of liquid is even; This static pressure is directly proportional with the height of liquid, has measured the static pressure of container bottom, just can know the height of liquid level.Because in the coking chemical industry level gauging, factors such as measuring media ubiquity thickness, crystallization, burn into high temperature detect data distortion, there are problems such as environmental pollution in maintenance difficult.Specific as follows:
1, because factor piezometric tube routes such as measuring media ubiquity thickness, crystallization, burn into high temperature cause the measurement distortion in reasons such as accumulated slag, crystallizations, the liquid level distortion, serious restriction safety is given birth to.
2, maintenance the time must be broken off the process web member, carries out scarfing cinder after pulling down transmitter, and not only workload is bigger, and the measurement data distortion time is longer, and the residue contamination environment that goes out clearly.
3, the accumulated slag of frequently clearing up in the chemical industry pipeline works the mischief to the upkeep operation personnel are healthy.
Summary of the invention
The purpose of the utility model is to provide a kind of flange form differential pressure pressure unit flusher; Can clean the deposit of flange form differential pressure pressure transmitter isolation diaphragm front side easily; Fast and periodic flushing pressure detection loop; Guarantee that the pressure detecting system data are reliable, can alleviate maintainer's workload, improve working conditions.
The purpose of the utility model is achieved in that a kind of flange form differential pressure pressure unit flusher; Be included in the sample cock that connects on the outlet of process vessel; Sample cock is connecting flange form differential pressure pressure unit through flange; Between sample cock and flange form differential pressure pressure unit joint flange, washing ring is installed through sealing gasket; The structure of washing ring on the cylindrical wall of annulus, radially be provided with the symmetry two flushing ports, internal thread is being set in flushing port, in the flushing port therein through the valvular washpipe of the dressing that is threaded.
The utility model increases washing ring between transmitter and sample cock, with washing ring be installed in that process connects and isolating seal in the middle of, by means of the flushing port that is positioned at the washing ring side, can clean the deposit of isolation diaphragm front side easily.Be used to wash flange form differential pressure pressure transmitter isolation diaphragm, need not interrupt procedure and connect the maintenance of dismounting transmitter.During use behind the short tube of joining L=100mm in the G1/2 of the washing ring flushing port mounted valve and short tube, the plug blind plugging is used in no flushing port., the bits in the sampling pipe or crystal purged back get into systemic circulation in the process vessel through flushing port cleaning sampling pipe with steam, no longer drain into the ground pollution environment.The occasion of application flange form pressure, differential pressure transmitter measuring liquid level all can be implemented should technology.Need not dismantle the pressure instrumentation web member in the maintenance again, only need to insert steam soaking and get final product, shorten the processing time, alleviate maintenance workload through 4 ＂ short tubes.Accumulated slag, crystal in the sampling short tube no longer are disposed to ground, no longer contaminated environment.
The utility model has following effect:
Need not dismantle the process web member of pressure measurement pipeline when 1, the coking chemical pressure is measured the measuring instrument distortion again, only need to insert steam soaking and get final product, shorten the processing time, alleviate maintenance workload through 4 ＂ short tubes.
2, accumulated slag, the crystal in the pressure measurement pipeline sampling short tube no longer is disposed to ground, no longer contaminated environment.
3, can carry out planned a small amount of blowdown through flushing port, with accumulated slag, the crystallization situation in the inspection pressure measurement pipeline sampling short tube.It is true and reliable to keep detecting data constantly, reduces industrial accident and takes place.
4, alleviate the time of upkeep operation personnel workload and contact poisonous and harmful article greatly, reduce the harm healthy the maintenance personal.
The utility model has realized cleaning easily the deposit of flange form differential pressure pressure transmitter isolation diaphragm front side; Fast and periodic flushing pressure detection loop; Guaranteed that the pressure detecting system data are reliable, alleviated maintainer's workload, improved working condition.

Fig. 1 is the utility model mounting structure synoptic diagram;
Fig. 2 is the sectional structure synoptic diagram of washing ring.
Embodiment
A kind of flange form differential pressure pressure unit flusher; Like Fig. 1, shown in Figure 2; Be included in the sample cock 2 that connects on the outlet of process vessel 1; Sample cock 2 is connecting flange form differential pressure pressure unit 3 through flange, between sample cock 2 and flange form differential pressure pressure unit 3 joint flanges, through sealing gasket 5 washing ring 4 is installed, and the structure of washing ring 4 is for radially being provided with two flushing ports 7 of symmetry on the cylindrical wall of annulus; In flushing port 7, internal thread is being set, in the flushing port 7 therein through the valvular washpipe 6 of the dressing that is threaded.
The scope of application of the utility model and application prospect:
Flange form differential pressure pressure unit flusher.The occasion of sector application flange form pressure such as metallurgy, chemical industry, petrochemical industry, differential pressure transmitter measuring liquid level all can be implemented should technology.
