Problems solved by technology

[0004] However, the gas leakage alarm safety pressure reducing valve disclosed above only alarms for gas leakage, and cannot perform inductive alarms for the gas pressure at the air inlet.
In the process of air supply, when encountering a special emergency, the intake pressure of the intake port suddenly increases. At this time, if it is not discovered in time and effective countermeasures are taken, it is very likely to cause an accident

Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention discloses a gas pressure relief valve capable of achieving an alarm function through ringing. The gas pressure relief valve comprises a gas inlet pipe, a gas inlet pressure monitoring tank, a gas pressure relief tank, a gas outlet pipe and a gas inlet pressure monitoring device, wherein the gas inlet pressure monitoring device comprises a gas inlet pressure monitoring cylinder, a turbine structure, an alarm toggle wheel, a transmission shaft, a bell structure and a resistance adjusting mechanism; a tank body of the gas inlet pressure monitoring tank is divided by a partition plate to form a gas flowing cavity and a sound alarm cavity; the gas inlet pressure monitoring cylinder is contained in the gas flowing cavity; the turbine structure is rotationally arranged in the gas inlet pressure monitoring cylinder; the alarm toggle wheel is rotationally arranged in the sound alarm cavity; the turbine structure is connected with the alarm toggle wheel through the transmission shaft; and the resistance adjusting mechanism comprises an adjusting knob, a pressing sheet and a resistance adjusting elastic part. According to the gas pressure relief valve, the gas flow pressure of agas inlet of the pressure relief valve is monitored, and when the inlet pressure of the gas inlet increases a lot suddenly, alarming is achieved through ringing.

Description

technical field [0001] The invention relates to the technical field of gas pressure reducing valves, in particular to a gas pressure reducing valve which realizes an alarm function by ringing a bell. Background technique [0002] The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to keep the outlet pressure automatically stable. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of decompression. [0003] The prior art (CN90211217.1) discloses a gas leakage alarm safety pressure reducing valve, which can be used for gas supply pressure reduction, and can automatically close the pressure relief val...
