Description
Technical field
The utility model relates to a kind of valve field, specifically a kind of safety exhaust.
Background technique
Safety valve is in normally off under open-shut device is subject to External Force Acting, when the pressure medium in equipment or pipeline increases to over specified value, exceedes the Special valve of specified value by preventing pressure medium in pipeline or equipment to discharge medium outside system.Safety valve belongs to self-acting valve class, and be mainly used on boiler, pressure vessels and pipes, pilot pressure is no more than specified value, has run important protective action to personal safety and equipment.Safety exhaust is the one of safety valve, is mainly used in the discharge to pressurized gas.Safety exhaust safety coefficient is in the market low, and exhaust efficiency is low.
Model utility content
The purpose of this utility model is to provide a kind of safety exhaust, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of safety exhaust, comprises valve body, valve gap, shell, first spring, second spring, first sideboard, second sideboard, suction port, air outlet, bleed passage, pressure monitor control system, gas-filled pump, cylinder pushing device and seal ring, described body base is provided with suction port, body top is provided with valve gap, body wall is provided with air outlet, axis along valve body is provided with first sideboard that can move up and down above suction port, the second sideboard is provided with, the first sideboard above first sideboard, the first spring is provided with between second sideboard, the second spring is provided with between second sideboard and valve gap, bleed passage is provided with between suction port and suction port, suction port side is provided with pressure monitor, pressure monitor is connected with gas-filled pump by control system, gas-filled pump is connected with cylinder pushing device, and cylinder pushing device comprises piston, piston rod, piston rod one end is connected with cylinder pushing device, and the piston rod the other end is connected with piston through valve body and is placed in bleed passage.
As further program of the utility model: the first described sideboard, the second sideboard, valve gap are in coaxially.
As the utility model further scheme: described valve body is positioned at piston rod both sides and is provided with seal ring.
Compared with prior art, the beneficial effects of the utility model are: the first sideboard of the present utility model, to top offset, is communicated with suction port and air outlet, realizes pressure release; If after the first spring breaking down follows the string, when safety valve internal pressure is excessive, what the first sideboard and the first spring can be similar to regards a fixed block as, this fixed block upwards pushes the second active block stop under the effect of internal pressure, second active block stop is to top offset simultaneously, makes suction port and air outlet conducting; When the pressure monitor of suction port air pressure measure air pressure exceed limited range time, the atmospheric pressure value of monitoring is passed to control system by pressure monitor, during air pressure control system automatically control gas-filled pump venting cylinder pushing device is shunk, suction port is directly communicated with by bleed passage with air outlet, discharge pressurized gas, safe and reliable.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of safety exhaust.

Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1, a kind of safety exhaust, comprise valve body 1, valve gap 2, shell 3, first spring 4, second spring 5, first sideboard 6, second sideboard 7, suction port 8, air outlet 9, bleed passage 10, pressure monitor 11 control system 12, gas-filled pump 13, cylinder pushing device 14 and seal ring 17, suction port 8 is provided with bottom described valve body 1, valve body 1 top is provided with valve gap 2, valve body 1 sidewall is provided with air outlet 9, axis along valve body 1 is provided with first sideboard 6 that can move up and down above suction port 8, gas port 8 and air outlet 9 cut off by the first sideboard 6, are provided with the second sideboard 7, first sideboard 6 above the first sideboard 6, second sideboard 7, valve gap 2 is in coaxially, the first sideboard 6, the first spring 4 is provided with between second sideboard 7, the second spring 5 is provided with between second sideboard 7 and valve gap 2, bleed passage 10 is provided with between suction port 8 and suction port 9, suction port 8 side is provided with pressure monitor 11, pressure monitor 11 is connected with gas-filled pump 13 by control system 12, gas-filled pump 13 is connected with cylinder pushing device 14, and cylinder pushing device 14 comprises piston 15, piston rod 16, piston rod 16 one end is connected with cylinder pushing device 14, and piston rod 16 the other end is connected with piston 15 through valve body 1 and is placed in bleed passage 10, and valve body 1 is positioned at piston rod 16 both sides and is provided with seal ring 17.
Working principle of the present utility model is: when the utility model normally works, first sideboard upwards pushes the first spring, and the first spring also can push the second stir yourself baffle plate in the process of compression, and now the first sideboard is to top offset, be communicated with suction port and air outlet, realize pressure release; If after the first spring breaking down follows the string, when safety valve internal pressure is excessive, what the first sideboard and the first spring can be similar to regards a fixed block as, this fixed block upwards pushes the second active block stop under the effect of internal pressure, second active block stop upwards exerts a force and elastic telescopic mechanism is compressed, second active block stop is to top offset simultaneously, makes suction port and air outlet conducting; When the pressure monitor of suction port air pressure measure air pressure exceed limited range time, the atmospheric pressure value of monitoring is passed to control system by pressure monitor, during air pressure control system automatically control gas-filled pump venting cylinder pushing device is shunk, suction port is directly communicated with by bleed passage with air outlet, discharge pressurized gas, safe and reliable.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
