Description

Technical Field

[0001] The utility model relates to the technical field of valve regulating devices, and particularly relates to a device for regulating the pressure of an air compressor. Background Art

[0002] A screw air compressor compresses air through a high-speed rotating screw rod and then transports the compressed air to the working area. At the valve of the screw air compressor, the opening and closing of the intake butterfly valve are controlled by a cylinder pushing a connecting rod. However, it is difficult for the cylinder to ensure that the opening and closing size of the intake butterfly valve is constant. Especially when the screw air compressor is working, the screw air compressor will generate strong vibrations. When the cylinder controlling the intake butterfly valve is affected by strong vibrations, it is even more difficult to ensure the stability of the opening of the intake butterfly valve, resulting in unstable air flow size at the intake butterfly valve and also causing the output air pressure size to be non-constant, affecting the subsequent production process. Especially in the glass product manufacturing industry, when blowing glass bottles, unstable output air pressure is extremely likely to cause defects in the glass bottle forming process, affecting the production quality of glass bottles. Summary of the Invention

[0003] The purpose of the utility model is to provide a device for regulating the pressure of an air compressor to solve the problem that the intake butterfly valve on the existing screw air compressor is difficult to stably control.

[0004] The utility model is realized through the following technical solutions:

[0005] A device for regulating the pressure of an air compressor includes a mounting block, a regulating device, and a mounting and fixing component. The regulating device includes a regulating screw, the regulating screw is threadedly connected to the mounting block, the mounting block is provided with an inclined side, and a slope is provided at the inclined side. The regulating screw passes through the slope at the inclined side.

[0006] In a possible design, a regulating knob is fixed at one end of the regulating screw away from the slope.

[0007] In a possible design, a locking nut is further provided at one end of the regulating screw away from the slope, and the locking nut is threadedly connected to the regulating screw.

[0008] In a possible design, the mounting and fixing component includes a mounting hole opened on the mounting block and a locking screw.

[0009] In a possible design, the cross-section of the mounting hole is oblong.

[0010] In a possible design, the locking screw is threadedly connected to the mounting block.

[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0012] 1. The utility model is used to be installed at the butterfly valve of a screw air compressor. By controlling and adjusting the protruding state of the screw rod, the opening and closing of the valve are restricted, which can make up for the problems of insufficient control accuracy of the existing butterfly valve control system and unstable opening and closing of the valve in a vibration environment, effectively improving the stability of the output pressure of the screw air compressor. At the same time, the overall structure of the device is simple and easy to manufacture.

[0013] 2. In the utility model, the protruding length of the adjusting screw rod can be adjusted with high precision, enabling high-precision control of the opening and closing of the butterfly valve, making the air pressure output by the screw air compressor more stable and the pressure control accuracy higher. Description of the Drawings

[0014] The drawings described herein are used to provide a further understanding of the embodiments of the present utility model, form a part of this application, and do not constitute a limitation to the embodiments of the present utility model. In the drawings:

[0015] Figure 1 is a schematic structural diagram of the present utility model;

[0016] Figure 2 is a schematic structural diagram of the present utility model in a usage scenario.

[0017] The reference numerals represent: 1 - mounting block, 2 - adjusting screw rod, 3 - adjusting knob, 4 - locking nut, 5 - mounting hole, 6 - locking screw, 50 - butterfly valve control cylinder, 60 - valve control connecting rod, 70 - butterfly valve control shaft, 80 - mounting plate. Detailed Embodiment

[0018] To make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in combination with embodiments and drawings. The illustrative embodiments and descriptions of the present utility model are only used to explain the present utility model and do not constitute a limitation to the present utility model.

[0019] Embodiment, as Figures 1 to 2 shown, this embodiment includes a mounting block 1, an adjusting device and a mounting and fixing assembly. The adjusting device includes an adjusting screw rod 2. A first threaded hole is provided on the mounting block 1, and the adjusting screw rod 2 is threadedly connected to the mounting block 1 through this first threaded hole. A bevel edge is provided on the mounting block 1, and a slope is provided at this bevel edge. The adjusting screw rod 2 passes through the slope at this bevel edge. When the mounting block 1 is fixed at the butterfly valve of the screw air compressor, the design of this bevel edge can enable the valve control connecting rod 60 for controlling the butterfly valve to have a larger rotation range.

[0020] It should be noted that the opening and closing of the butterfly valve of the screw air compressor is controlled by the rotation state of the butterfly valve control shaft 70. One end of the butterfly valve control shaft 70 is fixed to one end of the valve control connecting rod 60, and the other end of the valve control connecting rod 60 is hinged to the end of the piston rod of the butterfly valve control cylinder 50. When the screw air compressor works, the opening state of the butterfly valve is controlled by the telescopic movement of the butterfly valve control cylinder 50. However, due to the large working vibration of the screw air compressor, the stability of the butterfly valve control cylinder 50 is poor, which further makes the opening and closing state of the valve unstable. Moreover, the poor stability of the butterfly valve control cylinder 50 also further results in poor opening accuracy of the valve at the butterfly valve.

[0021] This device can be installed at the butterfly valve of the screw air compressor through the installation and fixing components. After the entire device is installed, rotating the adjusting screw 2 can control the extending length of the adjusting screw 2 at the hypotenuse of the installation block 1. The extending length of the adjusting screw 2 at the hypotenuse determines the position state of the valve control connecting rod 60, and the extending length of the adjusting screw 2 at the hypotenuse can be adjusted with high precision. Finally, high-precision control of the opening and closing of the butterfly valve is achieved, making the air pressure output by the screw air compressor more stable and the pressure control accuracy higher.

[0022] Furthermore, to facilitate the adjustment of the adjusting screw 2, an adjusting knob 3 is fixed to the end of the adjusting screw 2 away from the inclined plane. The adjusting knob 3 makes the adjustment operation of the adjusting screw 2 more convenient and labor-saving.

[0023] In this embodiment, a locking nut 4 is also provided at the end of the adjusting screw 2 away from the inclined plane. The locking nut 4 is threadedly connected to the adjusting screw 2. The locking nut 4 can lock the relative position state between the adjusting screw 2 and the installation block 1. After the adjusting screw 2 is adjusted to the required position, manually hold the adjusting screw 2 fixed and rotate the locking nut 4 to make the locking nut 4 move towards the installation block 1 and fit with the installation block 1 until the locking nut 4 cannot be easily rotated. There is a large frictional force at the thread between the adjusting screw 2 and the installation block 1, and the adjusting screw 2 cannot easily rotate with the installation block 1, thereby completing the fixation of the relative position between the adjusting screw 2 and the installation block 1.

[0024] In this embodiment, the installation and fixing components include the installation hole 5 opened on the installation block 1 and the locking screw 6. The installation hole 5 is elongated. This elongated installation hole 5 is used to cooperate with the installation piece 80 at the butterfly valve of the screw air compressor to complete the installation and fixation of the entire device. The locking screw 6 is threadedly connected to the installation block 1. After rotating the locking screw 6, the locking screw 6 approaches the installation piece 80 at the installation hole 5, and the locking screw 6 presses the installation piece 80 against the hole wall of the installation hole 5, so that there is a large frictional force between the installation piece 80 and the hole wall of the installation hole 5, thereby fixing the entire installation block 1 to the installation piece 80.

[0025] It should be noted that the mounting plate 80 is a structural feature of the butterfly valve of the screw air compressor, and the strip design of the mounting hole 5 can be well adapted to the mounting plate 80, thereby completing the stable installation of the entire device, so that the entire device can remain stable after installation.

[0026] When in use, make one side of the inclined surface of the mounting block 1 face the valve control connecting rod 60, align the mounting hole 5 on the mounting block 1 with the mounting plate 80, then place the mounting block 1 on the mounting plate 80, rotate the locking screw 6, and fix the entire device on the butterfly valve of the screw air compressor. By controlling the butterfly valve control cylinder 50, the valve control connecting rod 60 is pushed to one side of the device, and then the adjusting screw 2 is rotated so that the adjusting screw 2 drives the valve control connecting rod 60 to accurately reach the desired position, and then the locking nut 4 is rotated to lock the adjusting screw 2. After the adjustment is completed, under the abutment of the adjusting screw 2 on the valve control connecting rod 60, the size of the butterfly valve port can remain stable.

[0027] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
