Universal body described in the utility model is by the body seat and cover following two parts and forms, and the bulb body is installed in the body seat, and universal body covers and is installed in bulb body lower end.
Locating flange described in the utility model is made of steel standard flange and short straight tube conjunction, and straight tube extends upward and forms the connecting rod moving conduit, is provided with curvilinear groove near handle position on the straight tube, and handle is installed in the curvilinear groove and can moves up and down.
In order to increase sealing effect, seal ring described in the utility model is the cydariform seal ring, and the seal ring intermediate portion is a ring bodies, and described ring bodies cross section is the oval drum type that two ends are cut by parallel sanction.
For attractive in appearance, handle described in the utility model top is provided with decorative cover.
The utility model is installed in groove jar inside, and its effect is the same with the discharging valve of the outside of installation, plays the on-off action of blocking discharge port, but is different from external valve, and when external valve suffered damage, built-in valve still can proper functioning.
The reliability of the built-in valve of the utility model, high safety.Good airproof performance, working life are strong.Its two, the first-time qualification rate height that the utility model is installed promptly not have too high requirement to installing, as long as guidance will be installed a little.The 3rd is that the user uses with simple to operate, and the operating time is short, but a few second complete operation soon.
Advantage of the present utility model is:
A. adopt universal body structure, the poor sealing phenomenon that the out-of-flatness when tube is installed at the bottom of the energy free adjustment causes.
B. adopt the cydariform seal ring, can under pressurized, produce radial expansion, enhanced leaktightness area (plane and a cylindrical).
C. adopt the curvilinear groove position structure, material saving, simple, easy to use, the raising reliability of installation.
