Abstract
The utility model discloses a breather valve of an oil storage tank. The breather valve comprises a casing, a vacuum valve disc, a pressure valve disc, a positive pressure exhaust port and a negative pressure sucking port, wherein the pressure valve disc and the vacuum valve disc are arranged inside the casing and coaxially distributed, a protective cover is arranged on the positive pressure exhaust port, and a filter screen is arranged on the negative pressure sucking port. The filter screen comprises a filter screen frame which is hinged to the outer surface of the casing. The breather valve is coaxially distributed, the filter screen is arranged on the negative pressure sucking port, and the breather valve is compact in structure, small in size, light in weight and good in safety.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of Tank's Breather Valve.
Background technology
Mechanical breather valve is the core component of Tank's Breathing System.Generally formed by pressure valve and vacuum valve two parts.
The pressure valve of mechanical breather valve and vacuum valve are that block form arranges that structure is bigger, heavy at present, and ventilation volume is little.
The admission port of vacuum valve is negative inspiratory pressure in addition, is easy to the inspiration foreign matter when big as negative pressure and stops up, and has influenced the breathing valve normal operation and causes danger.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of compact conformation, Tank's Breather Valve that safety is good.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: Tank's Breather Valve comprises housing, vacuum valve disc, pressure valve disc, malleation exhausr port and negative inspiratory pressure mouth; The pressure valve disc of vacuum valve disc is arranged on enclosure interior and coaxial arrangement; The malleation exhausr port is provided with protective cover, and the negative inspiratory pressure mouth is provided with filter screen.
As preferably, filter screen comprises screen frame, and the outside face of screen frame and housing is hinged.
The beneficial effects of the utility model are:
The employing coaxial type is arranged, at the negative inspiratory pressure mouth filter screen is set, compact conformation, and volume is little, and from heavy and light, safety is good.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model Tank's Breather Valve embodiment.
Among the figure, 1-housing, 2-pressure valve disc, 3-pressure valve rod, 4-vacuum valve disc, 5-vacuum valve rod, 6-protective cover, 7-gas hood, 8-screen frame.
The specific embodiment
Fig. 1 is Tank's Breather Valve, by housing 1, pressure valve disc 2, pressure valve seat, pressure valve rod 3, vacuum valve disc 4, vacuum valve seat, vacuum valve rod 5, and malleation exhausr port and negative inspiratory pressure mouth composition.
Vacuum valve seat and pressure valve seat are arranged on the inside of housing 1, the pressure valve seat is arranged on the top, vacuum valve seat is arranged on the below of pressure valve seat, and vacuum valve disc 4 is coaxial arrangement with pressure valve disc 2, and wherein vacuum valve rod 5 is enclosed within the endoporus of pressure valve rod 3 and can slides up and down.
The malleation exhausr port is provided with protective cover 6, and negative inspiratory pressure mouth place is provided with semi-round gas hood 7, and gas hood 7 belows are provided with filter screen.
Filter screen is contained in the screen frame 8, and the outside face of screen frame and housing 1 is hinged.Screen frame 8 be shaped as semicircle, consistent with the profile of the below import of gas hood 7.
Filter screen is set can prevents that the negative pressure suction inlet from stopping up, screen frame is convenient to cleaning, and is not easy to lose when unloading lower filter screen.
Above-described the utility model embodiment does not constitute the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
