Embodiment Construction

[0012] A pressure relief and noise reduction safety valve, as shown in the accompanying drawings, it includes a valve body 1 and a valve core 2, the valve body 1 is provided with an air inlet 11 and an exhaust port 12, and the exhaust port 12 is Several exhaust holes, the valve core 2 is slidingly installed in the valve body 1, and there is a valve between the valve core 2 and the valve body 1 that compresses the valve core 2 and the air inlet 11 Elastic pressing part 3 with sealing fit. The elastic pressing member 3 is a compression spring, and the compression spring is squeezed between the valve body 1 and the valve core 2, and the valve core 2 and the air inlet 11 are hermetically fitted by the spring pressure of the spring itself. Preferably, the exhaust holes are six radial exhaust holes uniformly distributed on the outer circumference of the valve body 1 . The exhaust hole is located at the sealing fit between the valve core 2 and the air inlet 11 . The outer end of th...

Abstract

The invention discloses a pressure relief and noise reduction safety valve, which comprises a valve body and a spool. An air inlet and air outlets are formed on the valve body; the air outlets are a plurality of vent holes; the spool is slidably arranged inside the valve body; and an elastic compaction piece for tightly pressing the spool to allow the spool to be in sealed fit with the air inlet is arranged between the spool and the valve body. The safety valve can guarantee normal use of an air reservoir, and reduces the noise of the air reservoir during pressure relief and improves the driving comfort of a locomotive driver.

Description

technical field [0001] The invention relates to a safety valve, in particular to a pressure relief and noise reduction safety valve. Background technique [0002] At present, the general locomotive equipped with an air brake device will use an air storage tank, and the air storage tank is equipped with a safety valve. When the pressure of the air storage tank reaches the limit value, the safety valve opens to release the pressure. However, due to the relatively concentrated airflow discharge of the current safety valve during pressure relief, it is easy to generate relatively large noise, which affects the comfort of the locomotive user driving the vehicle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pressure relief and noise reduction safety valve, which can ensure the normal use of the air storage tank, reduce the noise emitted by the air storage tank when the pressure is released, and improve the comfort...
