Description

Technical Field

[0001] This utility model relates to the field of gas drainer water level monitoring technology, specifically a differential pressure type remote monitoring device for high and low water levels in gas drainers. Background Technology

[0002] A gas drainer is a device used to remove condensate and impurities from gas pipelines. It reduces the impact of moisture and impurities on the equipment through condensation, filtration, or separation, ensuring the normal operation of the gas system. The water level inside the gas drainer needs to be monitored during use, thus requiring a specialized monitoring device.

[0003] Existing gas drainer monitoring devices typically have high and low water level sensors that come into contact with the medium, which can easily lead to corrosion of the detection equipment and blockage of the pipeline, thereby damaging the equipment and affecting the detection accuracy and reliability. To address this, we provide a differential pressure type remote monitoring device for high and low water levels in gas drainers. Utility Model Content

[0004] The purpose of this invention is to provide a differential pressure type remote monitoring device for high and low water levels in a gas drain valve, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a differential pressure type remote monitoring device for high and low water levels in a gas drainer, comprising a drainer body, a top cover plate fixedly connected to the top of the drainer body, a pressure transmitter installed on the top of the drainer body, the output end of the pressure transmitter being connected to a remote monitoring instrument via a signal transmission line, a low-pressure pipe and a high-pressure pipe being threadedly connected to both ends of the pressure transmitter respectively, the bottom end of the low-pressure pipe being fixed to the top of the top cover plate and communicating with the drainer body, the high-pressure pipe penetrating the top cover plate and extending to the inside of the drainer body, and the high-pressure pipe being connected to the top cover plate by a threaded connection.

[0006] Optionally, the bottom end of the low-pressure pipe is connected to the top of the upper cover plate by welding or threading.

[0007] Optionally, the remote monitoring device is bolted to the outside of the drain body.

[0008] Optionally, both the low-pressure pipe and the high-pressure pipe are L-shaped pipes, and the bends of the low-pressure pipe and the high-pressure pipe are located on both sides of the pressure transmitter.

[0009] The technical effects and advantages of this utility model are as follows: 1. This utility model utilizes the compression of the space inside the high-pressure pipe by the condensate water level, and transmits the pressure changes inside the high-pressure pipe to a remote monitoring instrument to accurately obtain the real-time water level height, thus ensuring the accuracy of the monitoring results.

[0010] 2. By using L-shaped high-pressure pipes and L-shaped low-pressure pipes, the vaporized water at the bends of the high-pressure and low-pressure pipes returns to the drain body, ensuring the drying effect of the pressure transmitter and thus ensuring the stability of the pressure transmitter during use.

[0011] 3. The high-pressure pipe is installed by fixing the threaded structure. When the high-pressure pipe is blocked, it can be removed from the top cover plate by fixing the threaded structure to facilitate the cleaning of the blockage. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] This utility model provides, for example Figure 1-2The device illustrates a differential pressure type high and low water level remote monitoring device for a gas drainer, comprising a drainer body 1, a top cover plate 2 fixedly connected to the top of the drainer body 1, a pressure transmitter 3 mounted on the top of the drainer body 1, and a remote monitoring instrument 5 connected to the output end of the pressure transmitter 3 via a signal transmission line 4. The remote monitoring instrument 5 is bolted to the outside of the drainer body 1. A low-pressure pipe 6 and a high-pressure pipe 7 are threadedly connected to both ends of the pressure transmitter 3, respectively. The bottom end of the low-pressure pipe 6 is fixed to the top of the top cover plate 2 and communicates with the drainer body 1. The high-pressure pipe 7 penetrates the top cover plate 2 and extends to the inside of the drainer body 1, with the bottom end of the high-pressure pipe 7 at the lowest condensate water level inside the drainer body 1. The high-pressure pipe 7 is connected to the top cover plate 2 via a threaded connection. When it is necessary to clear blockages in the high-pressure pipe 7... Rotating the high-pressure pipe 7 releases the constraint of the upper cover plate 2 on the high-pressure pipe 7, allowing the high-pressure pipe 7 to be removed and thus clearing any blockages inside. The bottom end of the low-pressure pipe 6 is connected to the top of the upper cover plate 2 by welding or threaded connection. The low-pressure pipe 6 will not come into contact with the water in the drain body 1, so blockages are unlikely to occur. It is generally welded to the upper cover plate 2. If it is also necessary to remove the low-pressure pipe 6, it can be installed on the upper cover plate 2 by threaded connection. Both the low-pressure pipe 6 and the high-pressure pipe 7 are L-shaped pipes, and the bends of the low-pressure pipe 6 and the high-pressure pipe 7 are located on both sides of the pressure transmitter 3. When water vapor condenses in the low-pressure pipe 6 and the high-pressure pipe 7, it can flow back into the drain body 1 along the high-pressure pipe 7 and the low-pressure pipe 6, thus ensuring that both ends of the pressure transmitter 3 are dry and clean during use.

[0016] The implementation principle of a differential pressure type high and low water level remote monitoring device for a gas drainer in this embodiment is as follows: 1. When the condensate in the drainer body 1 is lower than or equal to the lowest end of the high pressure pipe 7, the pressure in the low pressure pipe 6 and the high pressure pipe 7 is equal to the pressure in the drainer 1. At this time, the pressure at both ends of the pressure transmitter 3 is equal, and the water level height parameter output by the pressure transmitter to the remote monitor 5 is 0.

[0017] When the condensate in the drain body 1 submerges the lower end of the high-pressure pipe 7, the gas inside the high-pressure pipe 7 is compressed. The higher the water level that submerges the high-pressure pipe 7, the higher the gas pressure inside the high-pressure pipe 7, and the higher the water level height that the pressure transmitter 3 transmits to the remote detector 5.

[0018] The remote monitoring device 5 sets an upper and lower alarm limit for the water level. When the condensate water level in the drain body 1 rises to the set upper alarm limit, the upper alarm will be triggered, and the remote monitoring device 5 will send an upper alarm signal to the relevant management departments and personnel. When the condensate water level in the drain body 1 drops to the set lower alarm limit, the lower alarm will be triggered, and the remote monitoring device 5 will send a lower alarm signal to the relevant management departments and personnel.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
