Description

Technical Field

[0001] This utility model belongs to the field of intake control technology, specifically relating to an integrated intake structure for a screw compressor. Background Technology

[0002] The compression principle of a screw compressor is based on the rotational motion of a pair of parallel, meshing male and female rotors (screws). After the rotor grooves draw in gas, they are sealed by the casing wall to form a compression chamber. As the rotors rotate, the volume of the compression chamber decreases, the gas is compressed, and the pressure increases.

[0003] The intake regulation system is a key component of the screw compressor, and it is essential for ensuring the efficient and stable operation of the equipment.

[0004] The existing air intake structure has the following problems:

[0005] 1. Each component is set up separately, resulting in many parts and high cost;

[0006] 2. It cannot flexibly adjust the intake air flow according to the user's gas demand. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated intake structure for screw compressors.

[0008] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0009] An integrated intake structure for a screw compressor includes an intake valve, a butterfly valve, an adjusting lever, and a cylinder regulator;

[0010] The intake valve and the butterfly valve are connected in series on the intake pipeline of the screw compressor, and the intake valve is located between the butterfly valve and the screw compressor;

[0011] One end of the adjusting lever is connected to the output end of the cylinder adjuster, and the other end is connected to the slide plate of the butterfly valve used to adjust the opening.

[0012] The air source for the cylinder regulator comes from the oil separator tank connected to the screw compressor;

[0013] The air intake valve is also provided with an air inlet for connection to the oil separator tank.

[0014] Furthermore, the passage between the intake valve and the oil separator is controlled by an electromagnetic vent valve. With this structural design, when the user does not use gas, the screw compressor begins to unload, the electromagnetic vent valve is energized, and the high-pressure gas in the oil separator is discharged to the intake valve through the electromagnetic vent valve and then circulated back to the screw compressor, while the oil separator maintains a certain pressure. If the user still does not use gas after a certain period of time, the entire system will shut down.

[0015] Furthermore, the intake valve, butterfly valve, adjusting lever, cylinder regulator, and solenoid vent valve are integrated into one unit. This structural design, by integrating the intake valve, butterfly valve, adjusting lever, cylinder regulator, and solenoid vent valve into one unit, makes the structure more compact and facilitates adjustment of the overall installation position.

[0016] Furthermore, the intake valve is a one-way type, and the output end of the intake valve is used to connect to the screw compressor. When the air pressure on the output side of the intake valve is greater than the air pressure on the output side, the intake valve is in the conducting state. With this structural design, when the air pressure on the output side of the intake valve is greater than the air pressure on the output side, gas enters the screw compressor to supplement the gas. The one-way nature of the intake valve can prevent gas backflow.

[0017] Furthermore, the passage between the cylinder regulator and the oil separator is provided with a throttling orifice. This structural design allows the throttling orifice to control the gas flow rate entering the cylinder regulator.

[0018] The beneficial effects of this utility model are:

[0019] 1. It can flexibly adjust the intake air flow according to the user's gas demand. Specifically, when the user's gas consumption decreases, the pressure in the oil separator increases, and the gas flows into the cylinder regulator through the pipeline. Driven by the pressurized gas, the cylinder regulator has enough power to drive the adjusting lever to rotate. The adjusting lever then drives the slide plate on the butterfly valve to move. At this time, the slide plate drives the butterfly valve to reduce the opening, thereby narrowing the gas passage and reducing the intake air volume, so as to balance the intake and exhaust of the entire system and reduce energy consumption. When the user's gas consumption is high, the cylinder regulator does not have enough pressurized gas, its output end resets, and drives the adjusting lever to reverse. The slide plate on the butterfly valve moves in the opposite direction, driving the butterfly valve to expand the opening, thereby expanding the gas passage and increasing the intake air volume.

[0020] 2. The intake valve, butterfly valve, adjusting lever, cylinder regulator and solenoid vent valve are integrated into one unit, making the structure more compact, facilitating the adjustment of the overall installation position, and reducing costs through integration.

The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model; these descriptions are explanatory and exemplary, and should not be construed as limiting the implementation methods or the scope of protection of this utility model.

These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0033] Example 1

[0034] like Figure 1 As shown, this embodiment provides an integrated intake structure for a screw compressor, including an intake valve 1, a butterfly valve 2, an adjusting lever 3, and a cylinder regulator 4;

[0035] Intake valve 1 and butterfly valve 2 are connected in series on the intake pipeline of screw compressor 6, with intake valve 1 located between butterfly valve 2 and screw compressor 6;

[0036] One end of the adjusting lever 3 is connected to the output end of the cylinder adjuster 4, and the other end is connected to the slide plate of the butterfly valve 2 for adjusting the opening.

[0037] The air source for cylinder regulator 4 comes from oil separator 7, which is connected to screw compressor 6;

[0038] The intake valve 1 is also provided with an intake port for connection with the oil separator 7.

[0039] In this embodiment, clean air enters the screw compressor 6 sequentially through the butterfly valve 2 and the inlet valve 1, providing an air source for the screw compressor 6;

[0040] The slide plate on the butterfly valve 2 can rotate under the drive of the cylinder regulator 4 and the adjusting lever 3, thereby adjusting the opening of the butterfly valve 2 and controlling the amount of gas flowing into the intake valve 1. The gas flows into the screw compressor 6 through the intake valve 1 and then into the oil separator 7 from the screw compressor 6.

[0041] When the user's gas consumption decreases, the pressure in the oil separator 7 increases, and the gas flows into the cylinder regulator 4 through the pipeline. Driven by the pressurized gas, the cylinder regulator 4 has enough power to drive the regulating lever 3 to rotate. The regulating lever 3 then drives the sliding plate on the butterfly valve 2 to move. At this time, the sliding plate drives the butterfly valve 2 to reduce its opening, thereby narrowing the gas passage and reducing the intake volume, so that the intake and exhaust of the entire system are balanced and energy consumption is reduced. When the user's gas consumption is high, the cylinder regulator 4 does not have enough pressurized gas, its output end resets, and drives the regulating lever 3 to reverse. The sliding plate on the butterfly valve 2 moves in the opposite direction, driving the butterfly valve 2 to expand its opening, thereby expanding the gas passage and increasing the intake volume.

[0042] When the user stops using gas and the screw compressor begins to unload, the high-pressure gas in the oil separator 7 is discharged into the intake valve 1 through the intake port of the intake valve 1, and then circulates back to the screw compressor 6. Meanwhile, the oil separator 7 maintains a certain pressure. If the user still does not use gas after a certain period of time, the entire system will shut down.

[0043] Example 2

[0044] like Figure 1 As shown, this embodiment provides an integrated intake structure for a screw compressor. The difference from Embodiment 1 is that the passage between the intake valve 1 and the oil separator 7 is controlled by an electromagnetic vent valve 8.

[0045] In this embodiment, when the user does not use gas and the screw compressor begins to unload, the electromagnetic vent valve 8 is energized, and the high-pressure gas in the oil separator 7 is discharged into the intake valve 1 through the electromagnetic vent valve 8 and then circulated back to the screw compressor 6. Meanwhile, the oil separator 7 maintains a certain pressure. If the user still does not use gas after a certain period of time, the entire system will shut down.

[0046] Example 3

[0047] like Figure 1 As shown, this embodiment provides an integrated intake structure for a screw compressor. The difference from embodiment 2 is that in this embodiment, the intake valve 1, butterfly valve 2, adjusting lever 3, cylinder regulator 4, and electromagnetic vent valve 8 are integrated into one unit.

[0048] In this embodiment, the intake valve 1, butterfly valve 2, adjusting lever 3, cylinder regulator 4 and electromagnetic vent valve 8 are integrated into one unit, making the structure more compact and facilitating the adjustment of the overall installation position.

[0049] Example 4

[0050] like Figure 1As shown, this embodiment provides an integrated intake structure for a screw compressor. The difference from Embodiment 1 is that the intake valve 1 is a one-way type. The output end of the intake valve 1 is used to connect to the screw compressor 6. When the air pressure on the output side of the intake valve 1 is greater than the air pressure on the output side, the intake valve 1 is in the conducting state.

[0051] In this embodiment, when the air pressure on the output side of the intake valve 1 is greater than the air pressure on the output side, the intake valve 1 opens, allowing gas to enter the screw compressor 6 to replenish the gas. The intake valve 1 is unidirectional, which can prevent gas backflow.

[0052] Example 5

[0053] like Figure 1 As shown, this embodiment provides an integrated intake structure for a screw compressor. The difference from Embodiment 1 is that the present invention provides a throttling orifice 5 in the passage between the cylinder regulator 4 and the oil separator 7.

[0054] In this embodiment, the gas flow rate entering the cylinder regulator 4 can be controlled through the throttle orifice 5.

[0055] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
