Abstract

The utility model discloses a vacuum pumping sealing valve which is composed of a suction nozzle (1) connected with a pumping gun, a connecting seat (3) fixed with a vacuum vessel body and a blocking ring (2), the two sides of which are respectively connected with the suction nozzle (1) and the connecting seat (3) into a whole, wherein, air outlet center holes (6) are arranged on the suction nozzle (1), the blocking ring (2) and the connecting seat (3), the air outlet center holes (6) are closed at the upper opening of the suction nozzle (1), the air outlet center holes (6) at the lower opening of the connecting seat (3) are communicated with the vacuum vessel body, and a knifing crevasse (4) is arranged on the suction nozzle (1); at least a sealing tendon ring (5) is arranged on the outer circumference of the connecting seat (3); after the structure is adopted, the vacuum pumping sealing valve overcomes the defects that the structure is complex, the installation is troublesome, the sealing effect is not ideal, and the cost is high exist in the original structure, and has the advantages that the structure is simple and compact, the use and the operation are convenient, the sealing effect is good, the cost is low, etc.

Description

Vacuumize seal valve

Technical field

The utility model relates to a kind of seal arrangement, the seal valve that uses on particularly a kind of vacuum-pumping container.

Background technique

Along with the development of society, people's living standard improves constantly, and the goods such as vacuum freshness retaining container, vacuum glass container that play vacuum suction cup, the store food of health-care physical therapy effect also more and more are subjected to liking of consumers in general; Said products is realized its purpose by vacuum, all is equipped with on its goods and vacuumizes seal valve; The present seal valve that vacuumizes generally is made up of valve seat, spool, stage clip and gland, valve seat is arranged on the lid, and spool is arranged in the valve seat and with the valve seat pore and cooperates, and stage clip is arranged on the spool, gland is fixed on the mount inlet of valve seat, and spool straight-bar end is located in the center hole of gland; There is following deficiency in it: the one, and complex structure, installation bother, sealing effect is undesirable; The 2nd, processing is inconvenient, cost is high, and for this reason, many associated production enterprises and knowledgeable people constantly research and develop, but do not have better products to solve the problems referred to above so far as yet.

Summary of the invention

For overcoming the existing above-mentioned disadvantage that seal valve exists that vacuumizes, the utility model purpose provide a kind of simple in structure, easy to install, sealability stable, cost is low vacuumizes seal valve.

The technological scheme that its technical problem that solves the utility model adopts, it by the suction nozzle that is connected with the rifle of bleeding, with the vacuum vessel body be fixedly coupled the seat, both sides respectively with suction nozzle and connecting base be connected as a single entity stop the circle form, suction nozzle, stop the circle and connecting base be provided with the center hole of giving vent to anger, give vent to anger center hole at the suction nozzle closed shape that becomes suitable for reading, the center hole of giving vent to anger of connecting base end opening communicates with the vacuum vessel body, and suction nozzle is provided with the cut that lancinates.

At least be provided with the sealed muscle ring that is connected as a single entity together on the excircle of described connecting base.

Described suction nozzle, stop the circle and connecting base be to make soft body by silicone rubber.

After adopting said structure, when the utility model uses connecting base is directly installed on the vacuum vessel body by the sealed muscle ring and gets final product; When seal valve cooperates with the rifle of bleeding when vacuumizing, the suction that the rifle of bleeding produces makes the suction nozzle distortion, air in the vacuum vessel body is from the cut section part sucking-off of suction nozzle, when the rifle of bleeding resetted, ambient pressure was greater than vacuum vessel body internal pressure, the sealing that resets of the cut section of suction nozzle, so repeatedly, can reach certain degree of vacuum in the vacuum vessel body, and the vacuum in the vacuum vessel body makes the cut section the suction-combining force of suction nozzle bigger, seals more reliable; When needing emptying in the vacuum vessel body, only need firmly pinch suction nozzle and make its distortion, air enters in the vacuum vessel body and can finish from the cut section of suction nozzle; Have simple and compact for structure, use characteristics such as easy to operate, good sealing effect, cost are low.

Embodiment

Shown in Figure 1, vacuumize the specific embodiments of seal valve for the utility model is a kind of, it by the suction nozzle 1 that is connected with the rifle of bleeding, be fixedly coupled seat 3, both sides with the vacuum vessel body and 2 form with the circle that stops that suction nozzle 1 and connecting base 3 are connected as a single entity respectively, suction nozzle 1, stop the circle 2 and connecting base 3 be provided with the center hole 6 of giving vent to anger, give vent to anger center hole 6 at suction nozzle 1 closed shape that becomes suitable for reading, the center hole 6 of giving vent to anger of connecting base 3 end openings communicates with the vacuum vessel body, and suction nozzle 1 is provided with the cut 4 that lancinates.The excircle of described connecting base 3 is provided with the sealed muscle ring 5 that two roads are connected as a single entity, and it is convenient that this not only makes connecting base 3 and vacuum body install and fix, and good seal performance.Described suction nozzle 1, stop the circle 2 and connecting base 3 be to make soft body by silicone rubber.

Claims (3)

1, a kind of seal valve that vacuumizes, it is characterized in that: it by the suction nozzle (1) that is connected with the rifle of bleeding, be fixedly coupled seat (3), both sides with the vacuum vessel body and form with the circle (2) that stops that suction nozzle (1) and connecting base (3) are connected as a single entity respectively, suction nozzle (1), stop that circle (2) and connecting base (3) are provided with the center hole of giving vent to anger (6), give vent to anger center hole (6) at suction nozzle (1) closed shape that becomes suitable for reading, the center hole of giving vent to anger (6) of connecting base (3) end opening communicates with the vacuum vessel body, and suction nozzle (1) is provided with cut (4).

2, the seal valve that vacuumizes according to claim 1 is characterized in that: be provided with the sealed muscle ring (5) that is connected as a single entity together on the excircle of described connecting base (3) at least.
