Example Embodiment

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] see Figure 1-5, the present invention provides a technical solution: an integrated fire-resisting breathing valve that can adjust the pressure of the breathing valve, comprising a breathing valve body 1, and the bottom of the breathing valve body 1 is fixedly connected with a flange 2. The side is connected with a fire-resisting element 3, which is used to prevent the flame from burning outward, and a replacement mechanism 4 i...

Abstract

The invention discloses an integrated fire-retardant breather valve capable of adjusting breather valve pressure, which comprises a breather valve body, the bottom of the breather valve body is fixedly communicated with a flange, one side of the breather valve body is communicated with a fire-retardant element, a replacement mechanism is arranged in the fire-retardant element, and the top of the breather valve body is fixedly connected with a valve cover through a bolt. The top of the valve deck and the interior of the breather valve body are provided with pressure adjusting mechanisms. According to the integrated fire-retardant breather valve capable of adjusting the pressure of the breather valve, the pressure adjusting mechanism is arranged, a pressing plate is rotated to be pressed downwards, so that an adjusting plate is rotated from a first adjusting groove to a pressing groove and slides downwards till a second adjusting groove is clamped, and adjustment of the pressure of the breather valve through external operation is achieved; according to the breather valve, the traditional step of disassembling the valve disc is avoided, so that the pressure is more convenient to adjust, and the step of stopping the work of the breather valve is reduced, so that the use efficiency of the breather valve is improved.

Description

technical field [0001] The invention relates to the technical field of breathing valves, in particular to an integrated fire-resisting breathing valve capable of adjusting the pressure of the breathing valve. Background technique [0002] Breathing valve refers to a valve that not only ensures that the storage tank space is isolated from the atmosphere within a certain pressure range, but also communicates (breathes) with the atmosphere when it exceeds or falls below this pressure range; its function is to prevent the storage tank from overpressure or The vacuum causes damage, and at the same time can reduce the evaporation loss of the stored liquid; it is mainly composed of valve seat, valve cover, rain cover and two sets of opening and closing devices controlled by vacuum and pressure; the opening and closing devices include valve flaps, guide rods, springs, Spring seat and sealing ring, etc.; when the pressure in the tank reaches the rated positive exhalation pressure, th...
