Abstract
The utility model discloses a thiophane concentration detection safety device which comprises a detection device connected to a high-pressure air pipe through a pipeline, wherein a nitrogen reducing valve is arranged on the pipeline between the high-pressure air pipe and the detection device, the detection device is connected to a diffusing hole of the nitrogen reducing valve, a pressure transmitter is connected between the nitrogen reducing valve and the high-pressure air pipe, the input end of the nitrogen reducing valve is connected with the diffusing hole of the pressure transmitter, and the nitrogen reducing valve is connected with the diffusing hole of the pressure transmitter through a loose joint. The nitrogen reducing valve and the pressure transmitter are arranged between the detection device and the high-pressure air pipe, and the outlet pressure can be reduced according to the actual demand, thus the thiophane concentration detection safety device has the advantages of being high in precision and good in controllability, well ensuring the safety of the detection personal and an instrument, realizing automatic control of the fuel equipment, well optimizing control of fuel thiophane concentration detection, and being safe and environment friendly.
Description
Technical field
The utility model relates to thiophane concentration detection safety feature in a kind of combustion gas.
Background technology
The high-pressure outlet thiophane of urban district gas pipeline comes controlled pressure with valve when detecting at present, because the high-pressure outlet pressure of urban district gas pipeline is 4.0Mpa, and thiophane detector flow velocity is 500-600ml/ minute, in actual testing process, be difficult to controlled pressure, if hypertonia easily washes out the thiophane detector and the detection flexible pipe explosion personnel that cause are injured and property loss.
Summary of the invention
For solving the problem on the above-mentioned prior art, the utility model provides a kind of thiophane concentration simple in structure, safe, reliable, that be convenient to control to detect safety feature.
The utility model is realized in the following way:
A kind of thiophane concentration detects safety feature, comprises by pipeline being connected in pick-up unit on the high-pressure air pipe, is provided with the nitrogen reduction valve on the pipeline between described high-pressure air pipe and the pick-up unit, and pick-up unit is connected to nitrogen reduction valve diffusion mouth place.
Further, be connected with pressure unit between described nitrogen reduction valve and the high-pressure air pipe, the input end of nitrogen reduction valve is connected to the diffusion mouth place of pressure unit.
Further, between described nitrogen reduction valve and the pressure unit diffusion mouth loose joint being set is connected.
The utility model is by arranging nitrogen reduction valve and pressure unit between pick-up unit and high-pressure air pipe, just can lower according to the actual requirements top hole pressure, precision is high, controllability is good, guaranteed well the safety of testing staff and instrument, realization has well been optimized the control that combustion gas thiophane concentration is detected, safety, environmental protection to the robotization control of gas-fired equipment.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Shown in the figure: the 1-high-pressure air pipe; The 2-pressure unit; 3-nitrogen reduction valve; The 4-pick-up unit.
Embodiment
For the ease of those skilled in the art's understanding, to the utility model and effect and the advantage that can produce, the preferred embodiment of lifting this case is described in detail as follows below in conjunction with accompanying drawing.
As shown in Figure 1:
A kind of thiophane concentration detects safety feature, comprise by pipeline and be connected in pick-up unit 4 on the high-pressure air pipe 1, be provided with nitrogen reduction valve 3 on the pipeline between described high-pressure air pipe 1 and the pick-up unit 4, pick-up unit 4 is connected to nitrogen reduction valve 3 diffusion mouth places.
Be connected with pressure unit 2 between described nitrogen reduction valve 3 and the high-pressure air pipe 1, the input end of nitrogen reduction valve 3 is connected to the diffusion mouth place of pressure unit 2.
Between described nitrogen reduction valve 3 and pressure unit 2 diffusion mouths loose joint being set is connected, making its entrance is the plane loose joint, outlet is the sphere loose joint, just can use nitrogen reduction valve 3 to adjust pressure, make things convenient for the thiophane concentration in 4 pairs of combustion gas of pick-up unit to detect, degree of regulation is high, and is safe and reliable, when effectively stopping hypertonia, easily wash out the thiophane detector even make and detect the flexible pipe explosion personnel that cause and injure problem with property loss.
The content of mentioning in above-described embodiment is not to be to restriction of the present utility model, and without departing from the concept of the premise utility, any apparent replacement is all within protection domain of the present utility model.
