Description

Technical Field

[0001] This utility model relates to the technical field of steam pipeline system, specifically a heat loss self-compensating steam pipeline pressure stabilizing device. Background Technology

[0002] In industrial production, such as chemical, pharmaceutical, food processing, and metallurgical industries, the production processes of these industries usually rely on steam for heating, reaction, distillation, and other operations. These industries have high requirements for the stability of steam pressure. The heat loss self-compensating steam pipeline pressure stabilization device can ensure the smooth operation of the production process and the stability of product quality.

[0003] The existing heat loss self-compensating steam network pressure stabilization device still has the following problems when in use: The device is usually equipped with a heat exchanger extending into the steam transmission network for heat compensation. When steam is transported in the network, the heat transmission structure of the heat exchanger extending into the network is limited by the internal space of the network. Its actual contact area with the steam in the network is limited, and the actual heat exchange efficiency is limited. It cannot perform fast and effective heat loss compensation for the steam in the network. Utility Model Content

[0008] As a further embodiment of this utility model: a connecting port is opened at the center of each end of the pipe network body, and a pressure control mechanism is fixedly installed at each end of the pipe network body and at the opening of the connecting port. The pressure control mechanism includes a detection pipe fixedly installed at the opening of the connecting port, the detection pipe is equipped with a pressure sensor, and an electric control valve is fixedly installed at the interface of each of the two detection pipes at opposite ends. The electric control valve is connected to the pressure sensor on its corresponding side via a data cable.

[0009] As a further improvement of this utility model: a threaded mounting groove is provided at the center of the top of the detection pipe for the threaded installation of the pressure sensor on the corresponding side, and a first connecting joint is fixedly installed at the interface of each of the two electrically controlled valves at opposite ends.

[0010] As a further embodiment of this utility model: an arc-shaped seat is fixedly connected to the middle position of the outer side wall at both ends of the insulation tube sleeve; a set of connecting rods is fixedly connected to the middle of the two arc-shaped seats at one end apart; a mounting seat is fixedly connected to the two sets of connecting rods at one end apart; and a set of connecting rods consists of two rods arranged symmetrically.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, a high-efficiency heat loss compensation mechanism is provided in conjunction with the pipeline body. It includes an insulated sleeve fixedly fitted to the outside of the pipeline body. The pipeline body is made of heat-conducting material. The upper and lower ends of the insulated sleeve are provided with mating interfaces in a centrally symmetrical manner. Connecting seats and second connecting joints are provided at the two mating interfaces. The heat exchange medium conveying pipeline can be connected through the two second connecting joints to realize the circulation of the heat exchange medium in the insulated sleeve. Since the heat exchange medium has a large contact area with the annular outer surface of the pipeline body, its actual heat exchange efficiency is high. The heat exchange medium can quickly heat the steam in the pipeline body, so as to carry out rapid and effective heat loss compensation of the steam in the pipeline.

[0013] 2. In this utility model, an intelligent pressure control mechanism is installed at both ends of the pipeline. The pressure sensor of the pressure control mechanism can monitor the steam pressure in the pipeline in real time. When the pressure fluctuates, the electric control valve will analyze and judge according to the preset pressure value. If the pressure is lower than the set value, the electric control valve will adjust the steam input flow of the heat compensation device to increase the heat input of the steam and make the steam pressure rise. If the pressure is higher than the set value, the electric control valve will take corresponding measures to reduce the heat input and increase the steam discharge to reduce the pressure and ensure that the steam pressure is always kept within a stable range, which is more convenient.

The two mating interfaces 32 are provided with connecting seats 33 and second connecting joints 34. The heat exchange medium can be connected to the heat exchange medium conveying pipeline through the two second connecting joints 34 to realize the circulation of the heat exchange medium in the insulated sleeve 31.

The entire system is equipped with an intelligent pressure control mechanism 2, located at both ends of the pipeline body 1. The pressure sensor 23 of the pressure control mechanism 2 can monitor the steam pressure in the pipeline in real time.

If the pressure is lower than the set value, the electrically controlled valve 24 will adjust the steam input flow of the heat compensation device to increase the heat input of the steam and cause the steam pressure to rise. If the pressure is higher than the set value, the electrically controlled valve 24 will take corresponding measures to reduce heat input and increase steam discharge to lower the pressure, ensuring that the steam pressure remains within a stable range, which is quite convenient.

The heat exchange medium conveying pipeline can be connected through the two second connecting joints 34 to realize the circulation of the heat exchange medium in the insulation sleeve 31. Since the heat exchange medium has a large contact area with the annular outer surface of the pipe network body 1, its actual heat exchange efficiency is high. The heat exchange medium can pass through the pipe network body 1. The body 1 rapidly heats the steam inside, enabling quick and effective heat loss compensation for the steam in the pipeline network. Furthermore, it is equipped with an intelligent pressure control mechanism 2, located at both ends of the pipeline body 1. The pressure sensor 23 of the pressure control mechanism 2 monitors the steam pressure in the pipeline network in real time.

If the pressure is lower than the set value, the solenoid valve 24 adjusts the steam input flow of the heat compensation device to increase the heat input of the steam and raise the steam pressure. If the pressure is higher than the set value, the solenoid valve 24 takes corresponding measures to reduce heat input and increase steam discharge to lower the pressure, ensuring that the steam pressure remains within a stable range, which is quite convenient.
