Abstract
The invention discloses a meter temperature sleeve plugging and temperature-measuring device. A temperature sleeve is fixed on a monitoring point of a process equipment pipeline; the tail end of the temperature sleeve is provided with a uniform external thread tubular joint; a shut-off ball valve or a wedge type gate valve for plugging is arranged on the tubular joint; an inlet pipe of the valve is provided with internal thread matched with the tubular joint; an outlet on the other side of the valve is connected with a discharging lengthening pipe; and a temperature monitoring device is fixed on the inlet pipe of the valve. The meter temperature sleeve plugging and temperature-measuring device solves the leakage problem caused by scouring a closed detection end by a process medium and corrosion damage, can effectively stop leakage and measure temperature, and can also reasonably apply and release pressure in a process pipeline, wherein the process medium with corrosivity is intruded to other place along the valve and the lengthening pipe, so that a worker can close to the device and deal with the problem. In addition, for temperature measurement on important control temperature measuring points, the temperature measuring sleeve can be arranged on the inlet pipe connected with the valve and is connected with the temperature measuring device, so that leakage is stopped and temperature is measured.
Description
?
Technical field
The present invention relates to leak stopping temperature measuring equipment in the chemical industry smelting industry, especially a kind of instrument temperature sleeve pipe leak stopping temperature measuring equipment.
Background technology
Chemical industry smelting industry process equipment instrument temperature detection most of adopts thermopair, thermal resistance, adds the temperature sleeve pipe and carry out thermometric, and the temperature sleeve pipe is that M27 * 2 are threaded on the process equipment.Sealing test side in the insertion equipment very easily is subjected to washing away and the corrosion and damage leakage of processing medium.Particularly the new legacy system of my company of second half 2010 purifies saturated hot-water tower outlet temperature and steam mixer outlet temperature, has occurred repeatedly leakage accident continuously.The time of the new temperature-measuring casing some months of installing, just serious corrosion leakage problem has appearred.Leakage mostly is flammable explosive gas, deals with improperly and very easily causes static blast fire casualty or cause the total system parking.This type of accident also repeatedly took place in the past, and most of way loss of adopting decrement or parking to handle is comparatively serious.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of instrument temperature sleeve pipe leak stopping temperature measuring equipment.
Technical scheme: a kind of instrument temperature sleeve pipe leak stopping temperature measuring equipment, be fixed with the temperature sleeve pipe on the monitoring point of process equipment pipeline, the temperature tube ends all has unified male-pipe straight coupling, a leak stopping is installed with cutting off ball valve or contract formula gate valve on described tubular configured joint, the induction pipe of this valve is provided with the internal thread with the tubular configured joint coupling, is connected with the discharging extension pipe in the outlet of valve opposite side.
On described induction pipe, be fixed with the temperature sleeve pipe, the tubular configured joint of this temperature sleeve pipe other end is equipped with temperature measuring equipment, sealing monitoring cover is installed in the temperature sleeve pipe, in sealing monitoring cover occasionally thermal resistance of thermoelectricity is installed, this thermoelectricity occasionally lead-in wire of thermal resistance is connected with temperature measuring equipment after passing tubular configured joint.
The present invention utilizes the fixed sleeving of point for measuring temperature on the existing process pipe, on the tubular configured joint of this tube ends, install and cut off ball valve or contract formula gate valve, prevent that processing medium to the washing away and corrosion and damage and the leakage phenomenon that causes of sealing test side, can play the effect of leak stopping very effectively.Simultaneously, can also rationally discharge the process pipe internal pressure, be to have corrosive processing medium to be introduced to other places along valve and extension pipe, so that the staff can approaching and processing.In addition, to the thermometric of important control point for measuring temperature, can with induction pipe that valve is connected on temperature-measuring casing be installed and be connected with temperature measuring equipment.Thereby the realization leak stopping, the effect of release and thermometric.By repeatedly on probation and test, result of use ideal.For example, in May, 2010, " Aug. 1st three " system purification saturator outlet temperature sleeve pipe is because of the equipment medium corrosion and damage.Gas seriously leaks outside inflammable and explosive, and general purpose tool dare not be approaching because of being afraid of to produce electrostatic spark danger, and system can't normally be driven.At this in emergency circumstances, utilize the present invention to carry out leak stopping, add band during leak stopping and discharge along pressure release in the device for plugging by pressure medium, installation is closed contract formula gate valve after finishing, because of the reasonable no any leakage phenomenon of mentality of designing, in the situation leak stopping next time success of not influence production.In October, 2010, legacy system purified steam mixer outlet temperature casing corrosion leaked, and utilized this device leak stopping not influence production equally.In November, 2010, Aug. 1st three system purification steam mixer outlet temperature sleeve pipes also leaked, and utilized the method leak stopping success once more.Three leak stopping are that company has retrieved system shutdown accident and economic loss, have guaranteed the safety in production of system.In order to make this achievement improve more and apply, increase the temperature sleeve pipe on the induction pipe of valve and can leak stopping can recover again to measure that temperature uses at the chemical industry smelting industry.The recovery use achievement of mainly considering the important control temperature is perfect.
