Description

Technical Field

[0001] The present invention belongs to the technical field of valves, and in particular relates to a two-way regulating valve and a use method thereof. Background Art

[0002] In the process of gas well mining, boosting equipment such as compressors are usually used. The outlet pressure of this equipment remains basically stable, but because the actual intake pressure will fluctuate within a certain range, the outlet pressure or flow rate will also be affected and fluctuate. In order to eliminate this effect, a buffer device is usually added to the working chamber, and the buffer device is usually mainly a buffer tank. When the working chamber pressure is lower than the buffer tank pressure, the buffer tank will replenish air to the working chamber; when the working chamber pressure is higher than the buffer tank pressure, the working chamber will inflate the buffer tank. This design is intended to stabilize system pressure and flow, reduce pressure shocks, balance pulsation energy, extend equipment life, and optimize the operation of the entire system to reduce the damage that changes may cause to downstream pipelines and equipment.

[0003] However, since the working chamber pressure fluctuates within a certain range, the existing technology often uses complex adjustment mechanisms or process flows between the working chamber and the buffer tank, and requires real-time manual adjustment, resulting in low efficiency of the entire system, complex operation and maintenance processes, and high skill requirements for operators.

[0004] The authorization announcement number CN220850970U discloses a bidirectional controllable gas valve, which sequentially sets the gas nozzle, the limit sleeve, the bushing and the installation sleeve, and the gas nozzle and the limit sleeve are fixedly positioned and restricted in the through hole by the head-to-tail contact of the abutting end and the limiting end, leaving a flow gap for air flow between the limit sleeve and the gas nozzle, and a ball is clamped between the limiting end and the gas nozzle, and the ball is used to block the inlet and outlet of the through hole, and the flow end of the flow gap and the extrusion mechanism belong to the two ends of the ball to form a positional setting, so that the flow size of the flow gap can be adjusted by adjusting the extrusion mechanism. Although the invention can achieve bidirectional adjustment, the invention still needs to adjust the extrusion mechanism and cannot be adjusted automatically, and the parts such as the ball are small, which is only suitable for pressure regulation of small flow or low-pressure equipment, and cannot be suitable for all pressure regulation systems, and there is no treatment for possible impurities.

In order to better remove the impurities, some mesh plates with filter holes can be placed in the first groove 111 of the valve body.

[0058] The present invention also provides a method for using a two-way regulating valve, the method comprising a method S1 for replenishing air from a buffer tank to a working chamber and a method S2 for replenishing air from a working chamber to a buffer tank;

[0059] The method S1 for supplying gas from the buffer tank to the working chamber includes the following steps:

[0060] S11, when the pressure of the working chamber is lower than the pressure of the buffer tank, the first spring 620 is compressed, and the valve core 610 moves to the left, so that there is a gap between the valve core assembly 600 and the end cover 230, and the baffle 510 and the valve body 110 are in a close contact state;

[0061] S12, the gas in the buffer tank enters the valve body 110 through the through hole of the buffer connecting main pipeline 210 and the end cover 230;

[0062] S13, the gas in the valve body 110 enters the working chamber through the working chamber connecting pipe 300 to replenish gas into the working chamber.

[0063] The method S2 for supplying gas from the working chamber to the buffer tank includes the following steps:

[0064] S21, when the pressure of the working chamber is higher than the pressure of the buffer tank, the gas containing solid impurities in the working chamber enters the interior of the valve body 110 through the working chamber connecting pipe 300;

[0065] S22, the solid impurities are retained in the impurity storage assembly 400, at which time the valve core 610 is tightly fitted with the end cover 230, the moving rod assembly 900 moves upward, and pushes the push plate assembly 700 to move leftward;

[0066] S23, the gas in the valve body assembly 100 enters the adapter block assembly 800 through the air inlet cylinder 830, and pushes the rotating baffle assembly 500 to deflect, and flows into the buffer tank through the buffer connection bypass pipe 220 to replenish gas to the buffer tank.

[0067] It should be noted that the valve core 610 and the end cover 230 are in a close contact state as the initial state of the valve core 610, and the baffle 510 and the valve body 110 are in a close contact state as the initial state of the baffle 510. When there is a large pressure in the valve body 110, the third spring 840 is compressed, driving the spring connecting plate 910 to move upward, and the gas in the valve body 110 enters the adapter block assembly 800. The pressure difference on both sides of the third spring 840 becomes smaller, and the third spring 840 tends to reset. However, due to the friction between the push plate 710 and the push block 940, the recovery time becomes longer. Therefore, during use of the present invention, the length of the third spring 840 changes dynamically.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
