Abstract
The utility model relates to a safety device, in particular to a safety device for special sealing packing container. The utility model aims to solve the problem that current pressure relief technology by pressure relief port can only protect the packing container but may have adverse effect on the product(s). In the utility model, a protective cap (2) is connected and fixed via a bolt (1) to a connecting sleeve (4), and a thread column at end part of a filter (5) passes through the connecting sleeve (4) and screws into thread hole of a safety valve (7). The utility model is mounted on the special sealing packing container, so when atmosphere air pressure is lower than open pressure of the safety valve, the outer vent one-way valve of the bidirectional safety valve will open automatically so that a little gas will flow out; when atmosphere air pressure is higher than open pressure of the safety valve, the outer vent one-way valve of the bidirectional safety valve will open automatically so that a little gas will flow in; when the differential pressure is reduced equal to the re-closure pressure of the safety valve, the safety valve will be shut to maintain the internal-external pressure balance of the container, which protects both the container and the product(s) therein.
Description
Technical field
The utility model relates to a kind of safety device.
Background technology
The special-purpose sealed package of product is housed, and transportation or when carrying out air transport between Plain and plateau can produce the inside and outside difference of pressure of packing container, and the packing container to thin-wall construction produces harm easily.Existing solution adopts more is installed the relief port on container, when transporting, the relief port is opened.The defective of this settling mode is: the inside and outside gas of container communicates, and is unfavorable to quality supervision for arbitration, uses inconvenient operation.
The utility model content
The purpose of this utility model is to use the relief port release for solving to have now, can only protect packing container, to the disadvantageous problem of quality supervision for arbitration, and the safety device that provides a kind of special-purpose sealed package to use.The utility model can substitute the relief port, and is favourable to quality supervision for arbitration in the protection packing container, uses more convenient.
The technical solution of the utility model is achieved in that the utility model is made up of screw 1, the over cap 2 that has through hole, adapter sleeve 4, filter 5, seal ring 6 and safety valve 7; the over cap 2 that screw 1 will have through hole is fixedly connected on the adapter sleeve 4; the threaded column of filter 5 afterbodys is passed in the tapped bore that adapter sleeve 4 is spun on safety valve 7, is provided with seal ring 6 between adapter sleeve 4 and the safety valve 7.The utility model is installed on the special-purpose sealed package, and when the container ambient pressure was lower than opening pressure of safety valve, the outer logical check valve of bidirectional relief valve (or logical outward safety valve) was opened automatically, has a small amount of gas to flow out; When the container ambient pressure was higher than opening pressure of safety valve, the interior logical check valve of safety valve (or interior logical safety valve) was opened automatically, had a small amount of gas to flow into; When difference of pressure drops to safety valve again during confining pressure, safety valve is closed, and keeps the container internal and external pressure balance.The utility model has also been protected the product in the container when having protected packing container, and use is convenient especially.
Should note when the utility model is installed: 1, safety valve can be selected two positive and negative installations of one-way relief valves for use, an also optional bidirectional relief valve, should take care when selecting for use the response pressure of valve, confining pressure and maximum flow rate again make it satisfy the requirement of packing container bearing pressure and volume; 2, answer the leak tightness of assurance device, and guarantee the safety valve fixation.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model;
The specific embodiment
The specific embodiment one: present embodiment is described further below in conjunction with Fig. 1: present embodiment is made up of screw 1, the over cap 2 that has through hole, adapter sleeve 4, filter 5, seal ring 6 and safety valve 7; the over cap 2 that screw 1 will have through hole is fixedly connected on the adapter sleeve 4; the threaded column of filter 5 afterbodys is passed in the tapped bore that adapter sleeve 4 is spun on safety valve 7, is provided with seal ring 6 between adapter sleeve 4 and the safety valve 7.Adapter sleeve 4 and packing container 3 are by being welded to connect, and the used safety valve of present embodiment is the safety valve by the KA serial model No. of the big Air Movement Technologies Inc in Zhaoqing side, Guangdong production.Can select a bidirectional relief valve during use for use, also can select two positive and negative installations of one-way relief valves for use.
The specific embodiment two: present embodiment is described further below in conjunction with Fig. 1: the through hole that present embodiment has on the over cap 2 of through hole is low inside and high outside inclined hole.Low inside and high outside inclined hole can effectively prevent entering of rainwater.Other composition is identical with the specific embodiment one with annexation.
The specific embodiment three: present embodiment is described further below in conjunction with Fig. 1: the micro-pore diameter on the present embodiment filter 5 is 50～500 μ m, can effectively stop passing through of granule dust.Other composition is identical with the specific embodiment one with annexation.
Claims (3)
1, the safety device used of a kind of special-purpose sealed package; it is made up of screw (1), over cap (2), adapter sleeve (4), filter (5), seal ring (6) and safety valve (7); it is characterized in that: the over cap (2) that screw (1) will have through hole is fixedly connected on the adapter sleeve (4); the threaded column of filter (5) afterbody is passed adapter sleeve (4) and is spun in the tapped bore of safety valve (7), is provided with seal ring (6) between adapter sleeve (4) and the safety valve (7).
