Description
Technical field
The utility model relates to the pressure obtaning device of Portable water dew point detector.
Background technique
When the Portable water dew point detector detects the gas water dew point, need at first natural pressure hydraulic piping pressure gauge be dismantled, then hand-held steel flexible pipe is connected the water dew point detector with the pressure gauge cock on natural gas line, open afterwards detector pressure gauge root valve until full-gear, then open the detector control valve until full-gear, open again the detector atmospheric valve, detected front purging, turn down the detector atmospheric valve after having purged, control the gas rate of outflow not too fast, until detector is when consistent with the pressure of natural gas line, stop closing valve, start to detect water dew point.The pressure gauge disassembled on the natural pressure hydraulic piping because of needs while detecting water dew point like this makes and can't change by observation pipeline operating pressure when detecting water dew point, and because detector sampling flexible pipe directly manually is connected with the drain of pressure gauge cock on natural gas line, can not effectively control pressure and the flow of rock gas, and poor sealing while manually connecting, easily cause natural gas leaking, have potential safety hazard.In addition, the mode of this manual connection detector and natural gas line makes detection time longer, and ambient temperature is on the impact of water dew point instrument checkout value large (temperature is too low also can cause the instrument automatic shutdown), thereby affects the accuracy of data.
Summary of the invention
The purpose of this utility model is to provide a kind of pressure obtaning device of Portable water dew point detector, to solve the true problem of natural gas leaking, prohibited data detection easily caused in prior art when using the water dew point detector to detect water dew point.
In order to address the above problem, the utility model adopts following technological scheme: the pressure obtaning device of Portable water dew point detector, comprise the first joint and the second joint for being threaded with water dew point detector sampling catheter for being threaded with natural gas line that arrange on body and body, be provided with valve pocket in body, the first joint and the second joint are communicated with valve pocket by being located at intrinsic passage respectively, in valve pocket, be provided with for controlling the flow direction of rock gas in described passage and the spool of flow, pressure obtaning device also comprises the control gear of controlling the spool action.
Described valve pocket also is communicated with valve rod hole, and control gear is the valve rod be connected with spool of being located in valve rod hole, and described valve rod is provided with the Joystick for the regulating spool position outside body.
Described control gear is the electromagnet for the regulating spool position, and described spool is electromagnetic valve core.
Be provided with the 3rd joint for being threaded with GAUGE CONNECTOR in described body, the 3rd joint is communicated with valve pocket by being located at intrinsic passage.
Two valve pockets and two the second joints are arranged in described body, and valve pocket is corresponding one by one with the second joint.
The beneficial effects of the utility model: owing to being threaded with the detector sampling catheter by the second joint, by being used for being threaded with natural gas line with the first joint, therefore can realize being tightly connected between water dew point detector and natural gas line, need not adopt the manual Placement between the pressure gauge cock on flexible pipe and natural gas line in prior art, and then avoid in the prior art because of the manually poor natural gas leaking caused of connection sealing, the true problem of prohibited data detection.
Further, because the 3rd joint arranged on body can be used for being threaded with GAUGE CONNECTOR, therefore the utility model can be observed the pressure changing of natural gas line when detecting water dew point, do not affect the normal pressure reading of natural pressure hydraulic piping, the problem that the pressure gauge on the natural pressure hydraulic piping need have been disassembled while having avoided detecting water dew point in the prior art, the utility model can be arranged on the rock gas main pipeline for a long time is convenient to water dew point detection operation.
Further, body comprises two valve pockets and the second joint, and valve pocket and the second joint are corresponding one by one, so the utility model can be used for installing two water dew point detectors, can verify the accuracy that detects pipeline same position water dew point.
