Example is applied, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making
Every other embodiment obtained, fall within the protection scope of the utility model under the premise of creative work.
Current existing gas-fired equipment cannot be interfaced to gas-fired equipment to main pipeline pipeline occur gas leakage, high temperature
It with the gas (be pernicious to people gas) in hemi-closure space, makes and gas pipeline is turned on and off, be based on this, this is practical new
A kind of pipe switch device and intelligent gas pipeline that type embodiment provides, can relatively safe control gas pipeline.
To be filled to a kind of pipe switch disclosed in the utility model embodiment first convenient for understanding the present embodiment
It sets and describes in detail.
In one embodiment, the utility model embodiment provides a kind of pipe switch device, and the device is for setting
It is placed on gas pipeline, the structural block diagram of pipe switch device shown in Figure 1, as shown, the device includes successively connecting
Environmental sensor 10, intermediate relay 20 and the electromagnetic valve switch 30 connect further include and environmental sensor 10 and electromagnetic valve switch
30 power modules 40 being separately connected；Power module 40 is used to power to environmental sensor 10 and electromagnetic valve switch 30；Environment passes
Environmental signal is sent to intermediate relay 20 for acquiring environmental signal by sensor 10；Intermediate relay 20 is for receiving environment
Signal drives electromagnetic valve switch 30 to execute movement corresponding with environmental signal；Movement includes opening pipeline and shutdown pipeline.
The utility model embodiment provides a kind of pipe switch device, acquires environmental signal by environmental sensor, and
Environmental signal is sent to intermediate relay, intermediate relay receives environmental signal, and then drive electromagnetic valve switch execute with
The corresponding movement of environmental signal, turns on and off pipeline, to relatively safe control gas pipeline.
Specifically, the combustion gas that environmental sensor is used to detect in air is dense in pipe switch device provided in this embodiment
Temperature in degree and air, and will test signal and be sent to intermediate relay, when intermediate relay receives detection signal, band
Moving electromagnetic valve switch executes movement corresponding with detection signal.When environmental sensor detects gas concentration and air in air
In temperature when being less than corresponding preset threshold, detection signal at this time is sent to intermediate relay, when intermediate relay
When device receives the detection signal, drives electromagnetic valve switch to execute the movement for opening pipeline, make user that combustion gas can be used normally；
When environmental sensor detects the gas concentration in air more than the temperature in preset first threshold or/and air more than default
Second threshold when, detection signal at this time is sent to intermediate relay, when intermediate relay receives the detection signal,
It drives electromagnetic valve switch to execute the movement of shutdown pipeline, prevents the temperature in the gas concentration or/and air in air after of continuing rising
It is high.Since intermediate relay is by secured core, dynamic iron core, spring, movable contact, stationary contact, coil, connecting terminal and shell group
At when coil is powered, dynamic iron core acts actuation under electromagnetic force, drives movable contact movement, separates normally-closed contact, normally opened
Contact closure；Coil blackout, dynamic iron core drive movable contact to reset under the action of the spring.When sensor is sent to intermediate relay
Be normal signal when, intermediate relay coil be powered, give solenoid valve normal power supply, electromagnetic valve switch is open-minded, and gas pipeline is just
Often gas supply；When sensor to intermediate relay send be abnormal signal when, intermediate relay coil no power can not give electromagnetism
Valve normal power supply, electromagnetic valve switch shutdown, gas pipeline do not supply.
The structural block diagram of another pipe switch device shown in Figure 2 also illustrates ring on the basis of Fig. 1
The first intermediate relay that gas security 10a and temperature sensor 10b that border sensor 10 includes, intermediate relay 20 include
20a and the second intermediate relay 20b and fuse 50, communication module 60, alarm 70 and radiator fan 80, for the ease of reason
Solution is as follows to pipe switch device specific explanations shown in Fig. 2 below:
Wherein, gas security 10a is connected with the first intermediate relay 20a, and gas security 10a is for detecting air

Signal is spent, temperature sensor sends the temperature signal in the air of acquisition by communication module to external equipment.Wherein, channel radio
The communication mode of letter module can be wireless WiFi communication and radio honeycomb communication (2G, 3 G, 4 G or 5G etc.)；Wire communication mould
The communication mode of block can be to be communicated by modes such as twisted pair, coaxial cable and optical fiber, and external equipment can be user
Mobile phone, iPad etc., external equipment receives the signal of communication module transmission, if the signal is the combustion gas carried in air
The signal of concentration or/and temperature anomaly can prompt user to take timely measure.And existing device cannot achieve and outside mostly
The communication of portion's equipment, in gas leakage, user can not learn and take timely measure in time.
Alarm 70 is connected with environmental sensor, triggers alarm report when the environmental signal exception of environmental sensor acquisition
It is alert, i.e., alarm equipment alarm is triggered when the gas concentration abnormal signal in the air of gas security acquisition, works as temperature sensor
Alarm equipment alarm is equally triggered when temperature signal exception in the air of acquisition.In alarm equipment alarm, alarm can be issued
Preset sound (such as whistle or voice broadcast), with call user's attention；Alarm can also send alarm to external equipment and disappear
It ceases, the relevant informations such as the gas concentration exception in air or/and the temperature anomaly in air can be carried in the warning message,
With call user's attention to take timely measure.Radiator fan 80 is connect with power module, the quantity of radiator fan be it is multiple,
Radiator fan can effectively radiate to power module, and the heat distributed when preventing power module from working can not be discharged and lead
Cause the excessively high normal work for influencing power module of temperature.

Under the conditions of unpowered, that is, in the case where having a power failure, which is in off position, while preventing combustion gas
By the valve (closed state), i.e. A → solenoid valve control valve → B route is closed；Control route can artificially be adjusted: manually control A
→ hand control valve → B route switching gaseity (this function is in emergency circumstances standby functions), that is, user needs when having a power failure
By artificially adjusting turning on and off for control gas pipeline, as spare under power-off condition.
Under normal running conditions, A → hand control valve → B route is in off position.The temperature in space is detected (in space
Fixed point detection) and concentration of natural gas synthesis result detected, pair gas pipeline turns on and off state at this time for decision, i.e.,
The control that solenoid valve is turned on and off, turns on and off gas pipeline to have been made in above-mentioned Fig. 2 and illustrates,
This is repeated no more.
