Description
Technical field
The utility model relates to the transmission & distribution apparatus field of rock gas, especially a kind of natural gas transmission and distribution pressure governor heating equipment.
Background technique
In the transmission & distribution process of rock gas, can use in a large number pilot valve formula pressure governor (being also indirect-action type pressure regulator).In the time that the rock gas of transmission & distribution produces the pressure drop of 1bar, the temperature drop of 0.5 ℃ of will having an appointment, so in the time that the pressure drop of rock gas is excessive, the temperature drop of rock gas also can be very big.In addition, come in the winter time temporarily, ambient temperature also can be extremely low.It is that temperature is very low that above-mentioned two reasons cause mobile gas in pilot valve, as easy as rolling off a logly in this case causes pilot valve work undesired, directly affects the normal work of pressure governor main valve.Existing technological scheme is generally on pilot valve, to install heating tape additional, by improve the working environment of pilot valve for the gas-heated in pilot valve.But the mode of heating of heating tape causes its intensification effect very limited, is difficult to effectively promote the gas temperature in pilot valve, thereby cause pilot valve because of the too low Frequent Accidents causing of internal gas temperature.
Model utility content
Technical problem to be solved in the utility model is to provide the natural gas transmission and distribution pressure governor heating equipment of the gas in a kind of more effective heating pilot valve.
The utility model solves the technological scheme that its technical problem adopts: natural gas transmission and distribution pressure governor heating equipment, comprise heater and controller, described heater is fixedly connected with controller by controller connecting end, in heater, be provided with heating stick, described heating stick outer wall is provided with gas channel, on heater housing, be provided with suction port and relief opening, between described suction port and relief opening, communicate by gas channel, heating stick is connected with controller.
Further, be provided with temperature transducer in heater, described temperature transducer is connected with controller.
Further, gas channel is spiral air passage, and described spiral air channel around the axis Spiral distribution of heating stick in heating stick outer wall.
Further, heater bottom is provided with sewage draining exit.
The beneficial effects of the utility model are: the utility model is by arranging the gas channel of heating stick and heating stick outer wall, in the time that reality is used, cryogenic gas enters from suction port, and be transported to relief opening through gas channel, when through gas channel, through heating fully, guarantee that the gas temperature of discharging from relief opening reaches requirement.The utility model is simple in structure, designs ingeniously, can allow the sufficient heated air of the temperature of heating stick absorb, and can be applied to the pressure governor in natural gas transmission and distribution is heated.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
In figure, be labeled as: heater 1, suction port 11, relief opening 12, heating stick 13, heat hot galvanic couple 131, temperature transducer 14, gas channel 15, sewage draining exit 16, heater housing 17, controller 2, controller connecting end 21.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Natural gas transmission and distribution pressure governor heating equipment as shown in Figure 1, comprise heater 1 and controller 2, described heater 1 is fixedly connected with controller 2 by controller connecting end 21, in heater 1, be provided with heating stick 13, described heating stick 13 outer walls are provided with gas channel 15, on heater housing 17, be provided with suction port 11 and relief opening 12, between described suction port 11 and relief opening 12, communicate by gas channel 15, heating stick 13 is connected with controller 2.
In the time that reality is used, first heat by the heating stick 13 of controller 2 heater 1, as shown in Figure 1, described heating stick 13 can pass through heat hot galvanic couple 131.After excellent 13 temperature rises to be heated, air is passed into from suction port 11, described air is heated by the gas channel 15 of heating stick 13 outer walls, and finally discharges by relief opening 12, and the air after heating is heated pressure governor.In the time that needs stop heating, stop heating stick 13 heating by controller 2.
Control in order to allow the utility model realize automatically, can select such scheme: in heater 1, be provided with temperature transducer 14, described temperature transducer 14 is connected with controller 2.Setting up after temperature transducer 14, once gas temperature lower than setting value, temperature transducer 14 is delivered to controller 2 by gas temperature lower than this signal of setting value, 2 of controllers are opened heating sticks 13 heating the final temperature that improves.Otherwise, if heating stick 13 temperature are too high, temperature transducer 14 is delivered to controller 2 by gas temperature higher than this signal of setting value, controller stops heating stick 13 to heat, thereby allows heating stick 13 temperature reduce.Generally, in the time of set temperature sensor 14, as shown in Figure 1, can first-selected temperature transducer 14 be arranged in heating stick 13 to detected temperatures so preferably.
In order to make the heat exchange between heating stick 13 and air more abundant, gas channel 15 can be set to spiral air passage, and described spiral air channel around the axis Spiral distribution of heating stick 13 in heating stick 13 outer walls.As shown in Figure 1, spiral air passage around the axis Spiral distribution of heating stick 13 in heating stick 13 outer walls, when air flows in above-mentioned spiral air passage, can be fully and heating stick 13 carry out heat exchange, save the energy thereby so not only can improve heat exchange efficiency, also can accelerate exchange rate.
Because the air being passed in heater 1 can be mingled with impurity, can sewage draining exit 16 be set in heater 1 bottom.As shown in Figure 1, after the impurity of heater 1 bottom is stacked into a certain degree, only need open sewage draining exit 16, in general, sewage draining exit 16 is arranged at the position of closing on suction port 11 by first-selection, and filth-discharging effect is best like this.
