The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of improved vacuum bag valve, comprise valve base 1, 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, valve base 1 is provided with a tubular Connection Block 4, valve top cover 3 and tubular Connection Block 4 airtight fastenings, deflation hole 2 is arranged in the tubular Connection Block 4, also be provided with seat 5 in the valve of an inner ring and the airtight socket in 4 outer rings of tubular Connection Block between valve top cover 3 and the valve base 1, be provided with connecting strap 11 between the seat 5 in valve top cover 3 and the valve, the effect of connecting strap 11 guarantees that the valve top cover is under situation about opening, valve top cover 3 links to each other with seat 5 in the valve by connecting strap 11, then valve top cover 3 is not easy to lose, vacuum bag is in assembling vacuum bag valve, valve base 1 is installed in the vacuum compression bag, tubular Connection Block 4 passes mounting hole on the vacuum compression bag, part is bonding airtight with bag beyond the tubular Connection Block 4 of valve base, then on valve base 1 in the buckle closure valve seat 5, further improved sealing property, seat 5 also covers in valve base and the bonding part of bag in the valve simultaneously, makes product look more attractive in appearance on the whole.
Referring to Fig. 3, Fig. 4, be provided with the soft seal strip 6 that one deck is used to block deflation hole between valve base 1 and the valve top cover 3, seal strip 6 is arranged in the tubular Connection Block 4, the inside that is positioned at tubular Connection Block 4 on the valve base 1 is provided with a through hole 7, deflation hole 2 be distributed in through hole 7 around, seal strip 6 is provided with one and is used for the link 8 installed with through hole 7, seal strip 6 is by link 8 and 1 removable connection of valve base, the head of the link 8 of seal strip 6 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 8 and length and through hole are complementary.Because the head of seal strip 6 is that a upper bottom surface is greater than the round platform of through-hole diameter bottom surface less than through-hole diameter, so just make things convenient for the seal strip valve base 1 of packing into, through hole 7 is in the root position of seal strip 6 and can come off easily, guaranteed leak tightness, deflation hole 2 peripheries on the valve base 1 are provided with a circle and are used for raising up 9 with seal strip 6 offsets, be provided with in the valve top cover 3 circle be used for seal strip offset the position with raise up 9 corresponding to lower convexity 10, 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, be to guarantee after valve top cover 3 snaps on the valve base 1, seal strip 6 is compacted, cause the leak free effect, owing between valve base 1 and valve top cover 3, be provided with the seal strip 6 that one deck is used to block deflation hole, and seal strip 6 and valve base 1 connection, simultaneously after seal strip 6 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.
Working process after assembling:
When bleeding, open valve top cover 3, extraction equipments such as the dust collecting fan mouth of pipe of bleeding is cooperated with tubular Connection Block 4, begin to bleed, seal strip 6 breaks away from deflation hole 2 under the suction function that extraction equipment produces, this moment, seal strip can not come off from valve base, and air is extracted out from deflation hole owing to the effect of the round platform of seal strip 6 links 8 heads; Bleed and finish, close extraction equipment, seal strip promptly externally is adjacent to deflation hole under the gas pressure, buckle the valve top cover, on the valve top cover one circle compresses the outer ring of seal strip 4 downwards to lower convexity 10,9 outer rings that also upwards compress seal strip that raise up of valve base make extraneous air can not reflux in the vacuum compression bag.
