Abstract
The utility model relates to a sealing exhausting valve, which comprises a valve body. A bonnet is arranged in the middle of the top surface of the valve body, a bonnet pusher is arranged at the position close to the right end on the top surface of the bonnet, an exhausting hole plug is arranged in the middle of the bottom surface of the bonnet, a clamp is arranged at the right end of the bonnet, a fastening groove is arranged at the position, corresponding to the position of the clamp on the bonnet, at the right end of the valve body, a circular exhausting hole groove is arranged inside the valve body, an exhausting hole reinforcing net is arranged inside the exhausting hole groove, a semicircular exhausting hole fixing wall matching with the exhausting hole plug is arranged on the exhausting hole reinforcing net, a filter paper groove is arranged at the position, corresponding to the position of the exhausting hole reinforcing net, at the bottom of the valve body, and a filter paper groove reinforcing net is arranged inside the filter paper groove. The sealing exhausting valve has the advantages of prevention of air entering and existing due to the fact that the exhausting hole plug arranged on the lower surface of the bonnet can block an exhausting hole when the bonnet is closed and prevention of secondary opening to cause internal gas leakage due to the fact that the clamp at one end of the bonnet is fastened inside the fastening groove on the valve body when the bonnet is closed.
Description
Technical field
The utility model relates to a kind of sealing extraction valve.
Background technique
Similar in the market package bag series products can bleed, seal behind the small-sized object of packing into the small size vacuum seaming machine.But have following shortcoming: 1, heavy packages bag (putting a body into a coffin body bag etc. more than 2 meters as length) is difficult for using; 2, similar products only possess the vacuum suction function at present, but run into bag interior article situations such as deadly infectious disease bacterium, harmful gas, dust are arranged, no filtering function, and the gas that causes extracting out causes external contamination.
The model utility content
The purpose of this utility model provides a kind of sealing extraction valve, can block bleeder hole after closing, and prevents the air turnover; Closing valve gap can prevent that secondary from opening internal gas is leaked; The gas of in pumping process, fully extracting out in the filter bag.
The purpose of this utility model is to be achieved through the following technical solutions: a kind of sealing extraction valve, comprise valve body, the middle part of described valve body end face is provided with valve gap, the end face of valve gap is provided with the valve gap pushing hands near the right-hand member place, the middle part of valve gap bottom surface is provided with the stopple of bleeding, the right-hand member of valve gap is provided with dop, the right-hand member of valve body and corresponding section, valve gap upper chuck position are provided with draw-in groove, valve gap covers by the dop that cooperatively interacts and draw-in groove and valve body, the inside of valve body is provided with the circle hole slot of bleeding, the bleed inside of hole slot is provided with the bleeder hole reinforcing network, the bleeder hole reinforcing network is provided with fixedly wall of the semicircle bleeder hole that matches with the stopple of bleeding, the bottom surface of valve body and corresponding section, bleeder hole reinforcing network position are provided with the filter paper groove, be provided with filter paper groove reinforcing network in the filter paper groove, be provided with filter paper between filter paper groove reinforcing network and the bleeder hole reinforcing network, the both sides of filter paper groove are evenly distributed with some valve body rinforcement bars.
The beneficial effects of the utility model are: the bleeder hole periphery is provided with a circle groove and semicircle fixedly wall, is convenient to plug air exhauster; Be respectively equipped with reinforcing network on bleeder hole, the filter paper groove and stiffening rib is fixed, wind-force is crossed the holocaust filter paper when preventing to bleed; Be provided with the stopple of bleeding below the valve gap, can after closing, block bleeder hole, prevent the air turnover; Close valve gap, the dop of valve gap one end fastens in the draw-in groove on the valve body, prevents from that secondary from opening internal gas is leaked; The inner filter paper of installing of filter paper groove, the gas of in pumping process, fully extracting out in the filter bag.
