Detailed description of the invention
With specific embodiment, this utility model is elaborated below in conjunction with the accompanying drawings:
Specific embodiment, such as Fig. 1, shown in Fig. 2 and Fig. 3, a kind of accumulator venting plug with double-lip relief valve, including the cock body 1 being coaxially disposed, inner core 2 and relief valve 3, cock body 1 is the hollow structure of bottom opening, it is provided with screw thread on the outer wall of cock body 1 lower end, with battery container screw-threaded coupling, the upper surface of cock body 1 offers hole 103, location, the quantity in hole 103, location is four, hole 103, four location is arranged the most at equal intervals, when needing to be screwed on battery container venting plug, four pawls of four paws spanner are inserted into respectively in hole 103, a location, then rotating spanner, rapidly venting plug can be locked with battery container, time saving and energy saving, convenient and swift.The top of cock body 1 is provided with downwardly projecting boss 102, inner core 2 is the hollow structure of both ends open, inner core 2 is positioned at inside the hollow structure of cock body 1 and fixes with cock body 1 and is connected, air vent 101 is offered on cock body 1 sidewall, air vent 101 is positioned at above inner core 2 and connects with cock body 1 inside, relief valve 3 is between inner core 2 and boss 102, relief valve 3 includes spool and bonnet, the lower end of spool is inlaid in inside the hollow structure of inner core 2, the upper end of spool is fixing with the lower end of bonnet to be connected, the upper end of bonnet contacts with boss 102, lip 301 is offered on the sidewall of spool, the quantity of lip 301 is two, two lips 301 are arranged in spool lateral symmetry, lip 301 is positioned on the sidewall of the spool corresponding with air vent 101.Lip 301 too conference affects sealing effectiveness, and lip 301 is the least, does not opens in required pressure value range, so lip 301 degree of depth radially is set to 1.6mm, the cambered surface radius of lip 301 is set to 1.96mm, and chord length is set to 3.4mm.Lip 301 quantity is increased to two by one and two lips 301 are symmetrical arranged, can effectively prevent single lip 301 from not opening in requiring pressure limit value the appearance of situation, serve dual fail-safe effect, it is ensured that the concordance of product, and improve the qualification rate of product.
As to further improvement of the utility model, the upper surface of relief valve 3 spool is provided with outwardly edge, location, and location is along being overlapped on the upper surface of inner core 2, and location supports the effect of spool along playing, prevent spool from coming off downwards, preferably play sealing effectiveness.
As to further improvement of the utility model, the spool of relief valve 3, bonnet and location are along being formed in one structure, the height of relief valve 3 is 5.18mm, the height of bonnet is 1.8mm, the height on edge, location is 1.2mm, forming structure makes relief valve 3 entirety more solid and reliable, prevents stitching portion from phenomenon of rupture occurring.
As to further improvement of the utility model, boss 102 and cock body 1 are formed in one structure so that the connection between boss 102 and cock body 1 is more solid and reliable, prevents stitching portion from phenomenon of rupture occurring.
This utility model is in the specific implementation: after being installed in accumulator by venting plug, when inner core 2 internal gas pressure reaches certain value, location corresponding with lip 301 on relief valve 3 is along being formed gap by jack-up, so that the gas accumulated in inner core 2 hollow structure releases from gap, and discharge via air vent 101, the relief valve 3 of double-lip effectively prevent single lip and do not opens in requiring pressure limit value the generation of situation, serve the effect of dual fail-safe, ensure that homogeneity of product, and improve the qualification rate of product.
