Description
Technical field
The utility model belongs to a kind of pump drainage air valve, is specifically related to a kind of vacuum reservoir bag vacuum bag valve.
Background technology
Vacuum bag on the market can be used for various clothes of vacuum storage and household articles, such as clothing, case and bag and quilt cover etc., its principle is to discharge the interior air of bag by air valve to cause vacuum state, make the interior article of bag be isolated from the outside, prevent moldy metamorphism, and article can be compressed and conveniently store and carry in the back pkt. that deflates, especially the article of quilt cover and so on.Though vacuum bag valve on the market is of a great variety at present, generally the vacuum bag valve of Shi Yonging comprises top cover, middle cover and bottom, and its structure is comparatively complicated, and using is not easily, and the manufacturing process complexity, has increased cost.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of simple in structure, easy to use, sealing property vacuum bag valve preferably is provided.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of improved vacuum bag valve, comprise the deflation hole on valve base, the valve base and snap over the valve top cover that is used to cover deflation hole on the valve base, it is characterized in that: be provided with the soft seal strip that one deck is used to block deflation hole between described valve base and the valve top cover, valve base is provided with a through hole, described seal strip is provided with one and is used for the link installed with through hole, and seal strip is connected by link and valve base are removable.
The head of the link of described seal strip is a upper bottom surface greater than through-hole diameter and the bottom surface round platform less than through-hole diameter, and the diameter and the length of the diameter of the root of link and length and through hole are complementary.
Deflation hole periphery on the described valve base is provided with a circle and is used for and raising up that seal strip offsets.
Be provided with in the described valve top cover one the circle be used for seal strip offset the position with raise up corresponding to lower convexity.
Described seal strip is a sheet rubber.
Described valve base is provided with a tubular Connection Block, and the diameter of described tubular Connection Block and the external diameter of seal strip are complementary, valve top cover and the airtight fastening of tubular Connection Block.
Adopt said structure, owing between described valve base and valve top cover, be provided with the seal strip that one deck is used to block deflation hole, and seal strip and valve base connection, the suction function lower sealing piece that produces at extraction equipment can not come off from valve base, because the head of seal strip is a round platform, so just make things convenient for the seal strip valve base of packing into, through hole is in the root position of seal strip and can come off easily, guaranteed leak tightness, all be provided with a circle on valve base and the valve top cover and be used for the projection that offsets with seal strip, be to guarantee that seal strip is fixed motionless after the valve top cover snaps on the valve base, cause the leak free effect.Seal strip adopts the material of soft rubber simultaneously, its characteristic has compressibi1ity and rebound resilience good, permanent deformation has for a short time with sealing surface pastes full flexibility, resistance to ag(e)ing is good, convenient processing and manufacture durable in use, low price, draw materials easily, material compactness is good and be difficult for leaking medium, so fully guaranteed the leak tightness of vacuum bag valve, and when the valve top cover is opened, after the characteristic that its compressibi1ity and rebound resilience are good has guaranteed that again bag interior gas is gone out, exterior gas can't enter in the bag easily, above-mentioned is simple in structure, can reduce manufacturing cost, guarantee the better seal performance simultaneously again.

The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of improved vacuum bag valve, comprise valve base 1, be opened in the deflation hole 2 on the valve base 1 and snap over the valve top cover 3 that is used to cover deflation hole 2 on the valve base 1, be provided with the soft seal strip 4 that one deck is used to block deflation hole 2 between valve base 1 and the valve top cover 3, seal strip 4 adopts material such as rubber, valve base 1 is provided with a through hole 5 that is used to be connected and fixed seal strip 4, deflation hole 2 be distributed in through hole 5 around, seal strip 4 is provided with one and is used for the link 6 installed with through hole 5, seal strip 4 is by link 6 and 1 removable connection of valve base, owing between described valve base 1 and valve top cover 3, be provided with the seal strip 4 that one deck is used to block deflation hole 2, and seal strip 4 and valve base 1 connection, simultaneously after seal strip 4 adopts this material of rubber, its compressibi1ity and rebound resilience are good, permanent deformation has the flexibility of fitting with sealing surface for a short time, resistance to ag(e)ing is good, convenient processing and manufacture durable in use, low price, draw materials easily, material compactness is good and be difficult for leaking medium, so fully guarantee the leak tightness of vacuum bag valve and controlled manufacturing cost, then under the situation that valve top cover 3 is opened, after the characteristic that its compressibi1ity and rebound resilience are good had guaranteed that bag interior gas is gone out, exterior gas can't enter in the bag easily.The head 7 of the link 6 of seal strip 4 is a upper bottom surface greater than through hole 5 diameters and the bottom surface round platform less than through hole 5 diameters, and the diameter and the length of the diameter of the root 8 of link 6 and length and through hole 5 are complementary.Since the head 7 of seal strip 4 be a upper bottom surface greater than the round platform of through-hole diameter bottom surface less than through-hole diameter, so just make things convenient for seal strip 4 valve base 3 of packing into, through hole 5 is in the root position of seal strip 4 and can come off easily, has guaranteed leak tightness.
What deflation hole 2 peripheries on the valve base 1 were provided with that a circle is used to compress seal strip 4 raises up 9, valve top cover 3 be provided with a circle with raise up 9 corresponding to lower convexity 10, also be provided with a tubular Connection Block 11 in raise up 9 periphery of a circle of valve base 1, the external diameter of the diameter of tubular Connection Block 11 and seal strip 4 is complementary, valve top cover 3 and tubular Connection Block 11 airtight fastenings.Valve base 1 below is provided with some fins 12, to prevent bag another side and deflation hole 2 applyings and to cause bleeding not exclusively.
Adopting said structure, all be provided with a circle on valve base 1 and the valve top cover 3 and be used for the last lower convexity that offsets with seal strip, is to guarantee that seal strip 4 is compacted after valve top cover 3 snaps on the valve base 1, causes the leak free effect.
During assembling, valve base 1 is installed in the vacuum compression bag, on the valve base beyond the tubular Connection Block 11 flat and bag bonding airtight, tubular Connection Block 11 stretches out bag and can fasten with the valve top cover.When bleeding, open valve top cover 3, extraction equipments such as the dust collecting fan mouth of pipe of bleeding is cooperated with the tubular Connection Block, begin to bleed, seal strip 4 breaks away from deflation hole under the suction function that extraction equipment produces, this moment, seal strip can not come off from valve base 1 owing to the effect of the round platform of seal strip 4 link heads, and air is extracted out from deflation hole 2; Bleed and finish, close extraction equipment, seal strip 4 promptly externally is adjacent to deflation hole 2 under the gas pressure, buckle valve top cover 3, on the valve top cover 3 one circle compresses the outer ring of seal strip 4 downwards to lower convexity 10,9 outer rings that also upwards compress seal strip 4 that raise up of valve base make extraneous air can not reflux in the vacuum compression bag.
