Description
Technical field
The utility model belongs to coal gas detection technical field, is specifically related to a kind of gas detect sampler.
Background technology
According to the technical indicator of China standard GB/T 18047-2000 " compressed natural gas used as vehicle fuel ", hydrogen sulfide content≤15mg/m3.Rock gas is milk-toast, leak descendant sense of smell less than, do not know to there occurs leakage, so be easy to the accident of blasting yet.For the sake of security, energy unit is just filled with a kind of material odorous to rock gas at the head end of urban duct--malodorant.So, after generation pipeline gas leakage (particularly in the end of pipeline--indoor user), we can smell smell, know and there occurs gas leakage, and then take safety measures in time, avoid having an accident.
In order to provide the detection means of science to the control of the sulfuretted hydrogen in rock gas and malodorant and detection.General is all carry out on-line checkingi with professional sensor (namely popping one's head in).But these probes are all require a little more than under normal pressure, provide the sample gas of flow within the scope of 100ml/min ~ 200ml/min, change not quite could detect accurately.Due to the natural gas line pressure that will detect, be generally all greater than 50mbar, just need to reduce pressure and flow control and adjustment to pipe natural gas sampling.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of gas detect sampler, can sample gas reduce pressure and the regulable control of flow to pressure pipeline, provides stable sample gas to detect for detecting device.
The technical scheme that the utility model adopts is: a kind of gas detect sampler, comprise two ends and be provided with the hollow cylinder had, be connected to the cover plate of cylindrical shell upper end and be connected to the base plate of cylindrical shell lower end, described cover plate is connected with rain cover, described base plate lower surface is provided with the connector be connected with detected pipeline, described connector runs through described base plate, the side that connector is positioned at cylindrical shell is provided with miniature needle-valve, the needle valve core that described miniature needle-valve comprises needle-valve body and is connected with needle-valve body, described needle-valve body entrance point is connected with connector, needle-valve body endpiece is connected with sampling pipe by needle-valve connector, described cover plate is provided with thief hatch, thief hatch lower end is connected with the other end of sampling pipe by sampling head.
As preferably, between described cylindrical shell and cover plate, be provided with shell flange.
As preferably, described cover plate is connected by gib screw with between rain cover.
As preferably, between described sampling pipe and needle-valve endpiece, be provided with needle-valve gland bonnet.
The beneficial effects of the utility model are: sampler connector for being directly connected to the supervisor of detected gas so that take out sample gas for detection; Connect connector below base plate, connect miniature needle-valve above; Needle-valve gland bonnet is that sampling pipe exports with needle-valve the sealing friction top be connected; Needle-valve connector is that needle-valve exports the critical piece be connected with sampling pipe; The valve body import of microneedle is connected with connector, and outlet is connected with sampling pipe; Needle valve core is the critical piece of adjust flux and pressure, is mainly used in regulating sample airshed, controls to detect sample airshed in the scope of (100ml/min ~ 200ml/min); Cylindrical shell is used for connecting bottom board and cover plate; Sampling pipe connects microneedle valve outlet port, sample pneumatic transmission to thief hatch, detects for sensor; Shell flange is used for connector drum and cover plate; Gib screw is used for securing cover plate and rain cover; Cover plate connects thief hatch, protects miniature needle-valve, sampling pipe and sampling head; Sampling head detects sample gas for sensor provides; Rain cover is fixed on cover screw, static probe and prevent rainwater from drenching probe, protection sensor.
