Abstract
A toxic gas inspecting probe mounting and demounting safety device comprises a flexible air-proof coating and a valve, wherein the center of the air-proof coating is provided with a probe hole whose diameter is slightly smaller than the external diameter of the probe. One terminal of the device air-proof-connects with the tube wall, and the other terminal is applied for fixing various inspecting probes. When in use, the probe penetrates a rubber air-proof liner in the device through one terminal of the device and then enters the tube through a stainless ball on the fore of the device. When demounted for maintenance, the probe is plugged out slowly with a ball valve closed firstly when the probe moves the stainless ball valve to prevent the gas leak in the tube, and then the plugging out process of the probe is continued, thereby the utility model which has simple conformation and convenient employment effectively prevents the toxic gas in the flues from spraying out from the inspecting joint when the probe is being demounted, or air entrance from outside.
Description
Technical field
The utility model relates to the monitoring device of harmful gas, specifically is a kind of monitoring harmful gases probe dismounting safety device, is mainly used in all kinds of probes that monitoring harmful gases is installed.When probe inserted or extracts, this protective device can effectively prevent the leakage of harmful gas, avoids causing personal injury.
Background technology
At present, most pipeline gas parameter measurement all needs from outside to inside to insert in pipeline by duct wall all kinds of measuring sondes or sampling probe, as: the flow velocity probe, temp probe, gaseous contaminant analysis that are used for the pollution source continuous flue gas monitoring all adopt above-mentioned mounting means with sampling probe etc.This type of probe is operated in the environment of high dust, highly corrosive mostly, and for realizing continuous monitoring, probe need regularly be pulled down and carry out daily Maintenance and Repair.Probe is in the process of pulling down and reloading, have a large amount of high harmful gases by spraying (malleation occasion) in the mounting interface or a large amount of air being arranged by absorbing (being the occasion of negative pressure in the pipeline) in the mounting flange hole, high harmful gas ejection causes personal injury undoubtedly, and inhaled air can destroy the gas composition content in the pipeline, and this is unallowed in some application scenario.
Summary of the invention
The purpose of this utility model just provides a kind of monitoring harmful gases probe dismounting safety device, to solve that harmful gas in the process of dismounting monitoring probe that prior art exists overflows or air is inhaled into the problem of monitoring interface.
The technical solution of the utility model is: comprise the flexible gland and the valve that are tightly connected mutually, the center of sealing cover is provided with probe hole, and its diameter is slightly less than the external diameter of probe.
Described sealing shroud has flange by two ends cylindrical shell is connected with the monitoring probe interface, and wherein the central authorities of the flange of an end are provided with reducing, is provided with scrobicular ring at the inner peripheral surface of this reducing, and described sealing shroud embeds in this scrobicular ring; The flange of the described cylindrical shell other end connects described valve.
Described valve is a stainless steel ball valve, and its two ends are provided with flange, and wherein the flange of an end is connected with the flange of the other end of described cylindrical shell, and the flange of the other end is connected with the flue sniffing interface.
Described sealing shroud is 1～2mm for the magnitude of interference of monitoring probe external diameter.
Described sealing shroud is made by rubber.
One end and the walling of flue sniffing interface of this device are tightly connected, and the other end is used for fixing all kinds of measuring sondes.In the use, probe is inserted by the rubber seal lining that places device inside by an end of this device, enters pipeline through the stainless steel ball valve that is positioned at the device front end again.Pull down when safeguarding, will pop one's head in and slowly extract, after probe moves past stainless steel ball valve, close ball valve earlier, prevent that pipeline gas from leaking, continue to extract probe again, prevented that effectively the harmful gas in the flue from spraying from the monitoring interface when dismounting is popped one's head in, or the air of outside enters.Simple in structure, easy to use.
Description of drawings
General structure synoptic diagram when Fig. 1 is the utility model application;
Fig. 2 is the axial cross-sectional schematic of the utility model cylindrical shell.
Embodiment
Referring to Fig. 1 and Fig. 2, ball valve 2 of the present utility model is tightly connected into an integral body with rubber seal lining 4 by the cylindrical shell 3 that two ends have flange.The latus rectum of stainless steel ball valve 2 is greater than the external diameter of probe 1 front portion 11, should leave the gap of 5 millimeter during design.The internal diameter of rubber seal lining 4 need be slightly less than the external diameter of probe anterior 11, and the magnitude of interference is between 1-2mm.
The utility model is when using, and the flange of ball valve 2 left ends is connected with the monitoring interface 6 of walling of flue 7.The flange of cylindrical shell 3 right-hand members and the interface 5 of monitoring probe 1 link.Flange central authorities at cylindrical shell 3 right-hand members are provided with reducing, connect the ring body 8 that an inner peripheral surface has scrobicular ring in this reducing, and described sealing shroud 4 embeds in the scrobicular ring of this ring body 8.
Before monitoring probe is installed, ball valve 2 to be closed, harmful gas can not leak.During installation, anterior 11 right-hand members by cylindrical shell 3 of will popping one's head in earlier insert, and stop when the right-hand member of ball valve 2.Open ball valve 2 then, this moment probe anterior 11 guarantees that with the magnitude of interference of 4 of rubber seal linings harmful gas does not leak, and continues to insert probe, and fixedlying connected probe interface 5 with bolt in the back that puts in place with the right-hand member of cylindrical shell 3, arrives this installation process end.
Pull down when safeguarding, will pop one's head in and slowly extract out, when probe anterior 11 moves to the right-hand member of ball valve 2, close ball valve 2.Can pull down probe and safeguard that the sealing during the maintenance is realized by ball valve 2 this moment.
This device processing is simple, easy to use, and existing mounting means is not needed too much transformation, can realize effective security protection.
