[0002] Petroleum products are a general term for various commodities produced directly from petroleum or a part of petroleum as raw materials. When petroleum products are used, they will be tested. Physical and chemical testing of petroleum products refers to the process of measuring and analyzing the physical and chemical properties of petroleum products through a series of scientific methods and equipment. This process aims to ensure that the quality, performance and safety of petroleum products meet relevant standards or requirements. It requires the use of sensors with various characteristics, among which viscosity detection is a relatively important detection indicator.

When the soft block moves, the sliding bar can be driven to slide inside the fixed block, thereby compressing the spring, so that the soft block can move to the specified position. After the soft block moves to the specified position, the sensor body passes through the center position of the protective shell. After the protective shell moves to the specified position, the soft block is released, and then under the action of the spring elastic force, the sliding bar can be driven to slide inside the fixed block, thereby allowing the soft block to move to the specified position, so that the inner wall of the soft block can be closely fitted with the outer side of the sensor body, and then The sensor body can be fixed, and then the plug is aligned with the inside of the slot, so that the plug enters the inside of the slot, and at the same time the sealing cover reaches the specified position on the top of the protective shell, and the positioning bolt is rotated so that the positioning bolt can enter the inside of the first screw hole, so that the sealing cover can be tightly connected to the protective shell, and at the same time the sensor body can be protected, thereby preventing high-temperature and high-pressure oil from entering the inside of the sensor and affecting the normal use of the sensor. It solves the problem that the temperature of some oils is high and the oil pressure in the oil pipe is high when the oil flows inside the oil pipe, which may affect the use of the viscosity sensor to a certain extent, causing the oil to enter the inside of some electronic components, thereby affecting the service life of the viscosity sensor.

[0027] A fixing block 10 is fixedly connected to the interior of the inner ring 7 , and a spring 11 is welded to one side of the inner wall of the fixing block 10 .

[0028] It should be noted that when the staff is protecting the sensor body 2, they first push the soft block 44 to move according to the size of the sensor body 2, so that the soft block 44 can drive the sliding bar 43 to slide inside the fixed block 10, and at the same time compress the spring 11. After the soft block 44 moves to the specified position, the sensor body 2 passes through the inside of the protective shell 41, and then the soft block 44 is released. Under the elastic force of the spring 11, the inner circle of the soft block 44 is tightly fitted with the outer side of the sensor body 2. After the sensor body 2 is initially positioned, the staff aligns the insert block 5 with the slot 42 and pushes the sealing cover 1, so that the insert block 5 enters the specified position inside the slot 42, so that the sealing cover 1 can move to the specified position, and then rotates the positioning bolt 9 so that the positioning bolt 9 enters the inside of the sealing cover 1 and the first screw hole 8, and then the protective shell 41 and the sealing cover 1 can be assembled and positioned.

When the soft block 44 moves, it can drive the sliding bar 43 to move, and then the sliding bar 43 can drive the spring 11 to move, so that the spring 11 is compressed. After the soft block 44 moves to the specified position, the staff makes the sensor body 2 pass through the inside of the protective shell 41, and then loosens the soft block 44. Under the elastic force of the spring 11, the soft block 44 can be moved, and then the inner ring of the soft block 44 can be tightly fitted with the outer side of the sensor body 2, so that multiple soft blocks 44 can position and seal the upper half of the sensor body 2, and then align the plug 5 with the slot 42 and push the seal. Cover 1, so that the plug block 5 enters the specified position inside the slot 42, and at the same time the sealing cover 1 can move to the specified position, and then rotate the positioning bolt 9 so that the positioning bolt 9 enters the inside of the sealing cover 1 and the first screw hole 8, so that the protective shell 41 and the sealing cover 1 can be assembled and positioned, and then the staff connects the first connecting shell 3 and the second connecting shell 14, and places the first connecting shell 3 and the second connecting shell 14 at the specified position outside the sensor body 2, and then makes the sealing block 13 enter the inside of the sealing groove 15, so that the sealing strip on the rear surface of the first connecting shell 3 enters the inside of the connecting groove 16, and rotates the bolt 18 so that the bolt 18 moves to the specified position, so that the first connecting shell 3 and the second connecting shell 14 can be positioned and connected.
