[0031] Among them, a detailed grease requirement list for valves of various models and sizes can be established to improve station personnel's control over valve maintenance and grease injection.

[0032] First, by adding grease pumps with counters (volumetric counting devices for paste media) to maintenance teams and stations, the accuracy of the grease injection amount can be ensured to the greatest extent possible, thereby reducing the phenomenon of excessive or insufficient grease injection caused by human grease injection, improving the maintenance level of equipment, and preventing excess grease from entering the pipeline, thereby affecting filtering, metering, pressure regulation and other equipment.

[0033] Secondly, by establishing a detailed grease requirement table for valves of various models and sizes, the station personnel can further improve their control over the amount of grease injected during valve maintenance.

[0034] Third, valve grease and sealing grease are expensive. By properly controlling the amount of grease injected, the cost of equipment operation and maintenance can be greatly reduced, thereby reducing costs and increasing efficiency.

[0041] The beneficial effects of adopting the above further technical solution are: the reversing block is cleverly used to automatically change the energy of the grease injection equipment to change the grease inlet and outlet of the piston volume chamber, so as to achieve one volume count. By moving the piston rod, the sliding block is moved to change the inlet position in time, so as to achieve uninterrupted flow in the grease injection channel.

[0042] like Figure 1 As shown, further, the number of the shift forks 11 is two, the reversing counter 7 is located between the two shift forks 11 , and the two shift forks 11 are located on the sliding track of the reversing counter 7 .

By moving the piston rod, the sliding block is moved to change the inlet position in time, so as to achieve uninterrupted flow in the grease injection channel.

[0044] The two shift forks 11 can be tilted relative to the sliding block moving connecting rod 10 .

[0045] like Figure 1 As shown, further, a protrusion 12 is provided on the reversing counter 7 , and the two shift forks 11 are located on the sliding track of the protrusion 12 of the reversing counter 7 .

By moving the piston rod, the sliding block is moved to change the inlet position in time, so as to achieve uninterrupted flow in the grease injection channel.

[0047] like Figure 1 As shown, further, the inlet and outlet reversing slider 9 is an inverted U-shaped structure.

[0048] The beneficial effect of adopting the above further technical solution is that it is easy for the inlet and outlet reversing slider to slide in the first housing, so as to realize the switching of the inlet and outlet.

[0050] The beneficial effect of adopting the above further technical solution is: by moving the piston rod, the sliding block is moved to timely change the inlet position, so as to achieve uninterrupted flow in the grease injection channel.

[0051] The actual situation on site was investigated and it was found that the valve grease injection method is that the grease injection gun 400D model is estimated to be 1 ounce after about 50 presses at full stroke, the super grease injection gun model is estimated to be 1 ounce after about 25 presses at full stroke, and the pneumatic grease injection pump model is estimated to be 1 ounce after about 10 pumps. If the estimated amount is less, the maintenance and use of the valve will be ineffective and the valve life will be affected. If the estimated amount is more, it will be a waste and the excess grease will enter the pipeline, filter equipment, metering equipment, pressure regulating equipment, compressor equipment, etc., affecting the normal operation of the equipment.

[0052] In order to solve this problem, considering the difficulty of measuring the paste-filled grease, a new solid-state volumetric counting device (paste medium volumetric counting device) was developed. The ball valve seat was designed according to the conventional grease injection requirements to count one inch per ounce.

[0053] 1) In order to meet the requirements of valve grease injection, the measurement of quantity is changed to volume measurement, which is convenient for checking the ball valve seat and counting one inch and one ounce.

[0054] 2) Make clever use of the reversing block (import and export reversing slider) and automatically change the grease inlet and outlet of the piston volume chamber through the energy of the grease injection equipment (grease injection gun), so as to realize volume counting.

[0055] 3) The piston capacity is designed to be 1 ounce. The capacity of one piston just flows through 1 ounce, and the counter (reversing counter) also jumps a number, which is convenient for counting the amount of grease injected.

[0056] 4) By moving the piston rod (connecting rod 14), the sliding block (inlet and outlet reversing slider) is moved to timely change the inlet position to achieve uninterrupted flow in the grease injection channel.

[0057] 5) It is small in size, simple and convenient, and solves the problem of valve grease injection, which has always been a difficult problem.

[0058] like Figure 2 As shown, in addition, the present invention also provides a paste medium grease injection system, including a paste medium volumetric counting device as described in any one of the above, and also including: a grease injection gun 15, a coupler joint 16, the output end of the grease injection gun 15 is connected to the paste medium inlet 3 through a second pipeline 17, and the coupler joint 16 is connected to the paste medium outlet 4 through a third pipeline 18.

[0059] The beneficial effect of adopting the technical solution of the present invention is: by adding a grease injection pump with a paste medium volumetric counting device to the maintenance team and each station, the accuracy of the grease injection amount can be ensured to the maximum extent, thereby reducing the phenomenon of excessive or insufficient grease injection caused by artificial grease injection, improving the maintenance level of equipment, and avoiding excess grease from entering the pipeline, thereby affecting filtering, metering, pressure regulating and other equipment.

[0060] like Figure 2 As shown, further, a pressure gauge 19 is installed on the third pipeline 18.

[0061] The beneficial effects of adopting the above further technical solution are: facilitating intuitive observation of the working pressure of the paste medium grease injection system, and improving the stability and reliability of the paste medium grease injection system.

[0062] Grease guns and pumps equipped with counters (reversing counters) can ensure the accuracy of grease injection, and avoid the phenomenon of excessive or insufficient grease injection, thus ensuring that valve maintenance is in place and preventing excess grease from entering the pipeline and affecting filtering, metering, pressure regulating and other equipment. In addition, the establishment of a detailed grease requirement table for valves of various models and sizes can further improve the station personnel's control over valve maintenance and grease injection.

[0063] Valve grease and sealing grease are expensive. Through the reasonable control of the paste volumetric counting device (paste medium volumetric counting device), the equipment operation and maintenance costs can be greatly reduced, waste can be avoided, and costs can be reduced and efficiency can be increased.

[0064] The present invention belongs to the field of oil and gas pipeline operation. It can solve the problem of station personnel controlling valve maintenance and grease injection, ensure the accuracy of grease injection, and prevent excess grease from entering the pipeline and affecting filtering, metering, pressure regulating and other equipment. Reasonable use of grease to maintain valves makes expensive valve grease and sealing grease used reasonably to avoid waste.

[0065] During annual valve maintenance, ball valves and plugs need to be greased. Completing the greasing according to the prescribed amount is a big challenge for both new and old employees, and has always troubled equipment maintenance personnel at stations and maintenance teams. The emergence of paste volumetric counting devices (paste medium volumetric counting devices) has solved the problem of valve greasing, and its promotion prospects cannot be underestimated.
