Technical Field

[0002] With the development of the economy, the demand of enterprises for industrial steam and heat sources is increasing. Given the industry characteristics of heat-using enterprises, the steam consumption varies greatly between day and night. At the same time, due to the long distance of the heat supply network, it is time-consuming and laborious in heat network loss and drain management, and there is no significant effect, seriously affecting the safe operation of the heat network and the economic benefits of enterprises. In the actual transportation of steam or heat sources in the prior art, it is easy to be affected by temperature conditions and steam condenses into water, resulting in steam loss. And at night, the steam supply load of the heat network is large, and most of the conveying pipelines do not drain the end pipelines, causing the steam supply load of the pipelines to be too large and posing certain safety hazards. Content of the Utility Model

[0004] For a remote intelligent control drain device for industrial heating pipelines of the utility model, an intelligent control mechanism is connected to the rear end of the drain pipeline. The intelligent control mechanism can be composed of an upstream and a downstream, and two branches are respectively formed at the downstream; the upstream of the intelligent control mechanism includes a primary valve, and the rear end of the primary valve is respectively connected to two secondary valves; the rear end of one secondary valve is connected to a tertiary valve and an electric valve, and the electric valve has a remote control function; the rear end of the electric valve is communicated with the end water outlet; the rear end of the other secondary valve is connected to a drain valve, and the drain valve has a remote control function.

[0005] As a further improvement of the utility model, the drain pipeline includes a water supply pump, a heater, a main water supply valve, a water collection tank, a water storage tank and a water level control valve connected in sequence. The water level control valve is branched through a pipeline and flows to a water control valve and an air expansion vessel respectively; the lower end of the air expansion vessel is connected to a main drain pump.

[0006] As a further improvement of the utility model, the water level control valve is used to detect the water level threshold in the water storage tank. The water control valve opens and closes according to the detection threshold of the water level control valve, and the water control valve is communicated to the outside through a pipeline; when the water level threshold is too high, the water control valve can be opened to control the discharge of the water level in the water storage tank.

[0007] As a further improvement of the utility model, the remote control of the electric valve and the drain valve is connected to at least one remote control terminal.

[0008] As a further improvement of the present utility model, the remote control terminal includes a Bluetooth module and / or an Internet of Things module and / or an NFC module and / or an infrared module.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] By installing a remotely controllable electric valve and a remote operation platform to upgrade the steam trap group, the monitoring switch of the end-of-heat-network drainage and the opening and closing of the remote steam trap are realized, making the operation simple and convenient, so as to ensure pipeline safety and reduce energy consumption.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Specific Embodiment 1: Please refer to Figure 1 An industrial heating pipeline remote intelligent control drainage device, which includes an intelligent control mechanism that can be composed of an upstream and a downstream, and two branches are respectively formed at the downstream. The upstream of the intelligent control mechanism includes a primary valve 10, and the rear end of the primary valve 10 is respectively connected to a first secondary valve 11 and a second secondary valve 14. The rear end of the first secondary valve 11 is connected to a tertiary valve 12 and an electric valve 13. The electric valve 13 has a remote control function to monitor the pipeline status and open and close the pipeline in a timely manner. The rear end of the electric valve 13 is communicated with the end water outlet. The rear end of the second secondary valve 14 is connected to a steam trap 15. The steam trap 15 has a remote control function to monitor the pipeline status and open and close the pipeline for drainage in a timely manner. It should be noted here that the remote control functions of the electric valve 13 and the steam trap 15 can be connected to the Internet of Things or a Bluetooth module, etc.

[0016] Working principle:

[0017] The intelligent control mechanism installed at the rear side of the main drain pump of this utility model realizes automatic control of starting and stopping in real time by remotely controlling the electric valve and the steam trap respectively, making the operation simple and convenient.

[0018] Specific Embodiment 2: Please refer to Figure 2 An industrial heating pipeline remote intelligent control drain device, which includes a water supply pump 1, a heater 2, a main water supply valve 3, a water collection tank 4, a water storage tank 5, and a water level control valve 6 connected in sequence. The water level control valve 6 is branched through a pipeline and flows to a water control valve 7 and an atmospheric flash tank 8 respectively. The water control valve 7 opens and closes according to the detection threshold of the water level control valve 6. When the water level threshold is too high, the water control valve 7 can be opened to control the discharge of the water level in the water storage tank 5, and the water control valve 7 is connected to the outside through a pipeline. The lower end of the atmospheric flash tank 8 is connected to the main drain pump 9, and the main drain pump 9 is connected to the rear intelligent control mechanism.

[0019] Working principle:

[0020] The water provided by the water supply pump is heated by the heater and then stored in the water storage tank. The water level control valve is used to judge the water level threshold to open the water level control valve in real time for water conveyance. A diversion is set at the water level control valve. One pipeline passes through the control valve, and the control valve detects the threshold of the water level control valve. When the water level is too high, part of the water can be discharged through the control valve to prevent excessive pressure increase in the water storage volume. The other pipeline flows to the atmospheric flash tank to ensure the pressure balance inside and outside the pipeline and ensure pipeline drainage. The main drain pump is installed at the rear of the atmospheric flash tank to timely control the situation of the main drain pipeline.
