Summary of the invention
In order to solve above-mentioned problems of the prior art, the utility model discloses a kind of dustproof and anti-explosion inhalation valve, thus solve the problem of existing inhalation valve Shortcomings in dust-proof and fire prevention, by arranging filtration system, the air entering into chemical storage tank is can be good to carry out filtration treatment, removing dust wherein, prevent dust from entering in storage tank, prevent dust for the impact of inhalation valve sealing simultaneously, this inhalation valve can also play the explosion-proof effect of back-fire relief, reduces the threat of extraneous Mars to inhalation valve.
A kind of dustproof and anti-explosion inhalation valve, comprise inhalation valve frame, described inhalation valve frame is divided into breathes valve gap and inhalation valve cavity, described breathing valve gap and inhalation valve cavity are bolted, described inhalation valve inside cavity arranges negative cavity, venting cavity and malleation chamber, between described malleation chamber and negative cavity, communicating passage is set, between described malleation chamber and venting cavity, exhalation valve disc is set, suction valve disc is set between described negative cavity and vent valve, suction chamber and exhalation chamber is divided at venting cavity, the outside of described suction chamber connects one and filters flameproof apparatus, described filtration flameproof apparatus comprises sealed cistern, sucking pipe.
Further, described exhalation valve disc and suction valve disc are all be made up of the composite sheet of aluminium and ptfe ring, and centre arranges fixing core body and spacing hole, and the place that described inhalation valve cavity contacts with composite sheet arranges metal ring.
Further, the top of described sucking pipe arranges bending section, and is provided with filter screen in outlet port.
Further, the top of described sealed cistern arranges water supplement port, and closes with sealing cover, and bottom sets out the mouth of a river.
Further, described water outlet arranges control valve.
The sealed cistern that the utility model filters in the outlet port UNICOM one of suction chamber, the air entering into inhalation valve tentatively can be filtered by tank, especially in the area that some hazes are comparatively serious or plant environment is poor, in air, fine particles is more, water can adsorb fine particle, prevent the fine particles such as dust from entering into inhalation valve and chemical storage tank, also can prevent the hazards such as extraneous Mars from entering into storage tank; Use the composite sheet of aluminium and tetrafluoro packing ring as exhalation valve disc and the material sucking valve disc, aluminium is rigid material, not easily deform, and relative mass is lower, do not affect the use of inhalation valve, the sealing of tetrafluoro packing ring is better, and metal ring is provided with pointed projections, and what strengthen tetrafluoro packing ring and metal ring contacts sealing.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of dustproof and anti-explosion inhalation valve.
Embodiment
The utility model discloses a kind of dustproof and anti-explosion inhalation valve, by arranging filtration system, the air entering into chemical storage tank is can be good to carry out filtration treatment, removing dust wherein, prevent dust from entering in storage tank, prevent dust for the impact of inhalation valve sealing, this inhalation valve can also play the explosion-proof effect of back-fire relief simultaneously, reduces the threat of extraneous Mars to inhalation valve.
Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technological scheme in the utility model, obviously, that described is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope of the utility model protection.
Shown in Figure 1, a kind of dustproof and anti-explosion inhalation valve, comprise inhalation valve frame, described inhalation valve frame is divided into breathes valve gap 1 and inhalation valve cavity 2, described breathing valve gap 1 is bolted with inhalation valve cavity 2, described inhalation valve cavity 2 inside arranges negative cavity 3, venting cavity and malleation chamber 6, between described malleation chamber 6 and negative cavity 3, communicating passage 4 is set, between described malleation chamber 6 and venting cavity, exhalation valve disc 10 is set, arrange between described negative cavity 3 and vent valve and suck valve disc 7, suction chamber 8 and exhalation chamber 5 is divided at venting cavity, the outside of described suction chamber 8 connects one and filters flameproof apparatus, described filtration flameproof apparatus comprises sealed cistern 13, sucking pipe 15, the air entering into inhalation valve tentatively can be filtered by sealed cistern 13, especially in the area that some hazes are comparatively serious or plant environment is poor, in air, fine particles is more, water can adsorb fine particle, prevent the fine particles such as dust from entering into inhalation valve and chemical storage tank, also can prevent the hazards such as extraneous Mars from entering into storage tank.
