Description

Technical Field

[0001] The utility model relates to the technical field of compressor valves, in particular to a compressor valve with a buffer protection structure. Background Art

[0002] The compressor valve is an important component in the compressor used to control the timely intake and discharge of gas into and out of the cylinder. The valve is mainly composed of four parts: the valve seat, which has a gas channel that can be covered by the valve plate, and together with the valve plate, it locks the intake (or exhaust) channel and withstands the pressure difference between the inside and outside of the cylinder; the valve plate, which alternately opens and closes the valve seat channel; the spring, which pushes the valve plate to fall to the valve seat when closed, and prevents the valve plate from hitting the lift limiter in structures such as strip valves, spring valves and DC valves when open.

[0003] After searching the Chinese patent "A compressor valve with a buffer protection cover", the announcement number is "CN214837005U". This patent can elastically buffer the valve plate, valve seat and limit plate that are subjected to air pressure through the structural design of the buffer cylinder, cover plate, buffer strip and buffer spring, so as to prevent the valve plate, valve seat and limit plate from being broken and flying and causing safety problems. However, the protection effect of this device on the compressor valve is not ideal when it is used. The valve plate in the compressor valve is easily damaged under the impact of airflow for a long time, which is inconvenient to provide effective buffer protection for the compressor valve, reducing the service life of the device.

[0004] Therefore, a compressor valve with a buffer protection structure is proposed to solve the above problems. Utility Model Content

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a compressor air valve with a buffer protection structure, comprising a valve seat, a valve cover is arranged at the top of the valve seat, a valve plate is arranged between the valve seat and the valve cover, a screw rod is threadedly connected to the top of the valve cover, one end of the screw rod passes through the valve cover and the valve plate in sequence and is threadedly connected to the valve seat, and a buffer mechanism is provided at the top of the valve seat and the bottom end of the valve cover; wherein, the buffer mechanism includes a plurality of mounting grooves evenly distributed and opened at the top of the valve seat, a fixing rod is fixedly connected to the inner wall of the mounting groove, and a protection component is provided at the top of the valve cover.

[0007] Preferably, the buffer mechanism also includes a buffer spring sleeved on the outer wall of the fixed rod, the inner wall of the fixed rod is slidably connected to a support rod, one end of the support rod passes through the fixed rod and is fixedly connected to a buffer pad, the buffer spring is arranged at the bottom end of the buffer pad, the support rod can protect the valve plate through the buffer pad, the buffer pad cooperates with the buffer spring to drive the support rod to slide in the fixed rod to buffer and disperse the impact on the valve plate.

[0008] Preferably, a connecting plate is fixedly connected between the several buffer pads. The connecting plate connects the several buffer pads together to provide stable support for the valve plate, prevent the valve plate from being subjected to uneven force, and better disperse the force.

[0009] Preferably, the inner bottom wall of the valve cover is slidably connected to a support ring, and a plurality of evenly distributed first spring telescopic rods are fixedly connected between the support ring and the valve cover. The valve cover can support and protect the valve plate through the cooperation of the first spring telescopic rods and the support ring.

[0010] Preferably, a protective pad is fixedly connected to the bottom end of the support ring, and the support ring can improve the protection effect of the device on the valve plate through the protective pad, thereby increasing the service life of the valve plate.

[0011] Preferably, the protection assembly includes two nuts threadedly connected to one end of the screw rod, and a mounting ring is provided between one of the nuts and the valve cover. The mounting ring between the nut and the valve cover can limit the valve cover and reduce wear of the device.

[0012] Preferably, the inner bottom wall of the mounting ring is fixedly connected with several evenly distributed second spring telescopic rods, one end of the second spring telescopic rod is fixedly connected with a limiting ring, the bottom end of the limiting ring is fixedly connected with a rubber pad, and the mounting ring cooperates with the limiting ring through the second spring telescopic rod to provide limiting support for the valve cover, and the rubber pad can protect the surface of the valve cover.

[0013] The beneficial effects of the utility model are:

[0014] 1. By setting a buffer mechanism, when protecting the compressor air valve, the buffer spring on the valve seat cooperates with the buffer pad at one end of the support rod to support and protect the valve disc. When the compressor air valve is in use, the buffer pad squeezes the buffer spring, and the support rod slides in the fixed rod to disperse the pressure on the valve disc. The connecting plate can fix several buffer pads together to form a circular ring shape, which can better disperse the pressure. The support ring at the bottom end of the valve cover cooperates with the first spring telescopic rod to protect the valve disc. The protective pad at the bottom end of the support ring can effectively protect the valve disc in the compressor air valve by its protective effect on the valve disc, thereby increasing the service life of the compressor air valve.

[0015] 2. By setting up a protection component, when protecting the compressor air valve, the two nuts at the top of the screw rod can install the mounting ring on the top of the valve cover. The mounting ring cooperates with the limit ring through the second spring telescopic rod to limit the support of the valve cover, thereby reducing the wear of the device on the valve cover. The rubber pad at the bottom of the limit ring can buffer and protect the surface of the valve cover, thereby protecting the compressor air valve and improving the use effect of the compressor air valve.

The annular block formed between the connecting plate 306 and the buffer pad 305 can improve the protection effect of the device. The first spring telescopic rod 308 and the protection pad 309 at the bottom end of the support ring 307 can protect the top of the valve plate 4 and reduce the wear of the valve plate 4.
