Description

Technical Field

[0001] The utility model belongs to the technical field of production operation, and more specifically relates to a structure for preventing gas and liquid from directly contacting instrument equipment. Background Art

[0002] In the practice of production operation technology, it is necessary to monitor the production situation in real time through instrument equipment. Currently, the measurement is mostly carried out by directly connecting the instrument equipment to the transport pipe.

[0003] When the material is corrosive or the flow rate is high, it is easy to damage the instrument equipment, resulting in problems with the measurement results. In general, the existing technology has the problems of low test accuracy and high maintenance costs. Utility Model Content

[0004] In view of this, in order to improve measurement accuracy and reduce production costs, the utility model proposes a structure to prevent gas and liquid from directly contacting instrument equipment, including a tubular structure body 1 and a buffer structure 4. A first connection port 2 and a second connection port 3 are provided at both ends of the tubular structure body 1. The tubular structure body 1 is filled with gas. When the material is transmitted through the conveying pipe, the diverted material enters the tubular structure body 1 through the first connection port 2, forming a confrontation with the gas filled in the tubular structure body 1, squeezing the gas and squeezing the gas through the buffer structure 4 to reach the instrument equipment for detection. The instrument equipment achieves the monitoring effect through the change of air pressure. The buffer structure 4 is a spiral structure with the function of decelerating heat dissipation, which greatly reduces the impact of the material on the instrument equipment. The use of gas prevents corrosion to the instrument equipment, thereby improving the measurement accuracy and the service life of the instrument equipment.

[0005] A structure for preventing gas and liquid from directly contacting instrument equipment includes a tubular structure body 1, a first connection port 2 and a second connection port 3 arranged at both ends of the tubular structure, and is characterized in that: a buffer structure 4 is provided in the middle section of the tubular structure body 1, and the buffer structure 4 is a spiral structure. The tubular structure body 1 is filled with gas, and the tubular structure body 1 is connected to the diversion end 6 of the material conveying pipeline through the first connection port 2. The tubular structure body 1 is connected to the instrument equipment through the second connection port 3. When the material is transmitted through the conveying pipe, the material at the diversion end 6 of the material conveying pipeline enters the tubular structure body 1 through the first connection port 2, forming a confrontation with the gas filled in the tubular structure body 1, squeezing the gas and squeezing the gas through the buffer structure 4 to reach the instrument equipment for detection.

[0006] Furthermore, the diameter of the diversion end 6 of the material conveying pipeline is larger than the diameter of the tubular structure body 1, thereby forming a larger impact force against the gas filled in the tubular structure body 1, so that the material drives the gas to be transmitted to the instrument equipment.

[0007] Furthermore, the gas filled in the tubular structure body 1 should not react with the material, and is preferably an inert gas.

[0008] Furthermore, the first connection port 2 of the tubular structure body 1 is provided with a first connection part 21 with an external thread, and the second connection port 3 of the tubular structure body 1 is provided with a second connection part 31 with an internal thread. The first connection part 21 with an external thread is first threadedly connected to the diversion end 6 of the material conveying pipeline, and then the second connection part 31 with an internal thread is threadedly connected to the instrument equipment. Since the force directions of the first connection part 21 with an external thread and the second connection part 31 with an internal thread are opposite, it is convenient to install and the connection is tighter.

[0009] Furthermore, a limiting boss 22 is provided at the end of the first connecting portion 21 close to the tubular structure body 1 , and the limiting boss 22 can limit the screwing position.

[0010] Furthermore, the outer surface of the limiting boss 22 is symmetrically provided with at least one pair of first clamping planes 222 , and the first clamping planes 222 can also cooperate with fasteners to fasten the connection between the diversion end 6 of the material conveying pipeline and the tubular structure body 1 .

[0011] Furthermore, at least one pair of second clamping planes 333 are symmetrically provided on the outer surface of the second connecting portion 31 . The second clamping planes 333 can also cooperate with fasteners to fasten the connection between the instrument equipment and the tubular structure body 1 .

[0012] Furthermore, the first connection port 2 is connected to the material conveying pipe via the valve 5, so as to facilitate the subsequent disassembly, assembly and maintenance of the equipment.

[0013] Furthermore, the buffer structure 4 is formed by a plurality of transversely arranged hollow O-shaped structures connected end to end and spirally formed.

[0014] Furthermore, the tubular structure body 1 includes a gas circulation pipe 11, an anti-collision heating layer 12 and a metal anti-rust layer 13. The outer wall of the gas circulation pipe 11 is fixedly connected with the anti-collision heating layer 12, and the outside of the anti-collision heating layer 12 is fixedly connected with the metal anti-rust layer 13. The anti-collision heating layer 12 can heat the inside of the tubular structure body 1, reducing the impact of low temperature weather on the normal flow of gas in the tubular structure body 1.

[0015] The beneficial effect of the present invention is as follows: the present invention proposes a structure to prevent gas and liquid from directly contacting instrument equipment, comprising a tubular structure body 1 and a buffer structure 4. A first connecting port 2 and a second connecting port 3 are provided at both ends of the tubular structure body 1. The tubular structure body 1 is filled with gas. When the material is transmitted through the conveying pipe, the diverted material enters the tubular structure body 1 through the first connecting port 2, forming a confrontation with the gas filled in the tubular structure body 1, squeezing the gas and squeezing the gas through the buffer structure 4 to reach the instrument equipment for detection. The instrument equipment achieves a monitoring effect through air pressure changes. The buffer structure 4 is a spiral structure with deceleration and heat dissipation, which greatly reduces the impact of the material on the instrument equipment. The use of gas prevents corrosion to the instrument equipment, thereby improving measurement accuracy and the service life of the instrument equipment. BRIEF DESCRIPTION OF THE DRAWINGS
