Abstract
The invention discloses an all-weather T-shaped dead weight breather valve, which comprises a T-shaped valve body. A valve cavity is arranged in the valve body, air inlet and outlet ports A, a port B and a port C are arranged on the valve body, both the air inlet and outlet ports A are communicated with the valve cavity, the port B and the port C are used for balancing positive and negative pressure difference between the valve cavity and the outside, connecting flanges are mounted at the ports A, sealing flanges are mounted at both the port B and the port C, a movable inward-opening sealing cover is mounted on the sealing flange at the port B, a movable outward-opening sealing cover is mounted on the sealing flange at the port C, the top ends of the inward-opening sealing cover and the outward-opening sealing cover are hinged onto the valve body through hinges, and a sealing device is arranged between each sealing flange and the corresponding sealing cover. The all-weather T-shaped dead weight breather valve is simple in structure, convenient in maintenance and low in cost, and can be used for automatically protecting a closed container from damage of positive and negative pressure during use in an all-weather manner, automatically closing and protecting atmospheric environments.
Description
Technical field
The present invention relates to avoid the positive and negative bad automatic safety device that crushes in a kind of normal pressure class seal container use, relate in particular to a kind of round-the-clock T type dead-weight inhalation valve.
Background technique
At present; Extensively in being applied to various industrial fields, normal pressure class seal container can make in the container and the certain positive and negative pressure of generation between the barometric pressure when material turnover seal container normal pressure class seal container quilt; Seal container itself is damaged; Therefore, on most normal pressure class seal container inhalation valve is installed all, is used to guarantee when material turnover seal container, to avoid the destruction of positive negative pressure.
But the existing inhalation valve that is used for normal pressure class seal container exists complex structure, inconvenient maintenance, expensive shortcoming more, and the also straight-through atmosphere of the inhalation valve that has, and is so both dangerous, also atmosphere caused certain pollution.
Summary of the invention
The object of the present invention is to provide a kind of round-the-clock T type dead-weight inhalation valve; It can realize round-the-clock automatic protection seal container avoid in using positive and negative crush bad; And realize closing automatically, the protection atmosphere environment has characteristics simple in structure, easy to maintenance, that cost is low and versatility is good.
For reaching this purpose, the present invention adopts following technological scheme:
A kind of round-the-clock T type dead-weight inhalation valve, it comprises T type valve body, is valve pocket in the said valve body; It is characterized in that; Offer the turnover gas A mouth that all is connected with valve pocket and B, the C mouth of balance valve pocket and extraneous positive and negative pressure on the said valve body, on the said A mouth adpting flange is installed, said B, C mouth place all are equipped with sealing flange; On the sealing flange at said B mouth place mobilizable swing-in sealing cover is installed; On the sealing flange at said C mouth place mobilizable outward opening sealing cover is installed, the top of said swing-in sealing cover and outward opening sealing cover is articulated on the valve body through hinge, is provided with seal arrangement between said sealing flange and the corresponding sealing cover.
Especially, the angle of the center line of said B, C mouth 3 °～15 ° of tools all and between the horizontal line.
Especially, the pore size of said A, B, C mouth equates.
Especially, the valve body place of the said B mouth formation flange that extends internally, the sealing flange at this mouthful place is installed on the flange.
Especially, the centerline of said B, C mouth is on same straight line.
Especially, the center line of said B, C mouth and the angle between the horizontal line are 8 °.
Especially, said seal arrangement is the O RunddichtringO.
Beneficial effect of the present invention does, said round-the-clock T type dead-weight inhalation valve is compared with existing inhalation valve, and is not only simple in structure, easy to maintenance, cost is low; And can realize that round-the-clock automatic protection seal container avoids positive and negative in using and crush badly, and realize closing automatically the protection atmosphere environment.
Description of drawings
Fig. 1 is the structural representation of the round-the-clock T type dead-weight inhalation valve that provides of the specific embodiment of the invention 1.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the round-the-clock T type dead-weight inhalation valve that provides of the specific embodiment of the invention 1.
In the present embodiment, a kind of round-the-clock T type dead-weight inhalation valve comprises T type valve body 1, is valve pocket 2 in the said valve body 1; Offer all three mouths of A, B, C that be connected with valve pocket 2 and that pore size equates on the said valve body 1; Said A mouth place is equipped with adpting flange 3, and the center line of said adpting flange 3 can be installed on valve body 1 on the seal container through adpting flange 3 perpendicular to horizontal line; Pass in and out gas through the A mouth; Through B, C mouth balance valve pocket 2 and extraneous positive and negative pressure, the centerline of said B, C mouth is on same straight line, and valve body 1 place of said B mouth extends internally and forms flange 9; The sealing flange 4 at this mouthful place is installed on the flange 9; The top of the top of the sealing flange 4 at said B mouth place through hinge 5 hinged swing-in sealing covers 6 also is equipped with sealing flange 4 on the valve body 1 at said C mouth place, and the top that is installed on C mouth place sealing flange 4 is through the top of the hinged outward opening sealing cover 7 of hinge 5.
Be provided with O RunddichtringO 8 between said sealing flange 4 and the corresponding swing-in sealing cover 6, be provided with O RunddichtringO 8 between said sealing flange 4 and the corresponding outward opening sealing cover 7.
The center line of said B, C mouth and the angle between the horizontal line are 8 °, and this angle makes swing-in sealing cover 6 and outward opening sealing cover 7 after relying on its gravity to close, and better sealing effect is arranged.
Said round-the-clock T type dead-weight inhalation valve is installed in the peak of normal pressure class seal container through adpting flange 3; Its working principle is: when the air inlet of A mouth; When valve pocket 2 internal pressures were elevated to greater than barometric pressure, outward opening sealing cover 7 can be opened under the effect of valve pocket 2 internal pressures automatically; Swing-in sealing cover 6 is in closed condition under the effect of valve pocket 2 internal pressures simultaneously; When the A mouth is given vent to anger; Valve pocket 2 internal pressures are fallen the end to less than barometric pressure the time; Swing-in sealing cover 6 can be opened under the effect of external atmospheric pressure automatically, and outward opening sealing cover 7 is in closed condition under the effect of external atmospheric pressure simultaneously; When A mouth airless, when valve pocket 2 internal pressures equaled barometric pressure, swing-in sealing cover 6 can be closed under the effect of its gravity with outward opening sealing cover 7 automatically, and medium is closed in the seal container, protects atmosphere environment automatically.
It is especially obvious that above-mentioned round-the-clock T type dead-weight inhalation valve is applied to large-scale normal pressure class, material turnover amount is big, material passes in and out fireballing seal container protection effect.Can realize that round-the-clock automatic protection seal container avoids positive and negative in using and crush badly, and realize closing automatically the protection atmosphere environment.The variation of Manufacturing material can guarantee that T type inhalation valve has anticorrosion, fire prevention, characteristics such as antifreeze.
