Technical Field

The utility model mainly relates to the technical field of boilers, in particular to a high-sealing-performance end socket.

Background

The head can play the effect of end cover in the boiler use for the opening of shutoff boiler plays sealed effect, but the head that adopts among the prior art can not be when guaranteeing sealed effect, the inside ascending pressure of dispersion boiler, thereby can not increase the sealed effect of head and boiler opening part.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a high-sealing-performance end socket which comprises an end socket body 1 with a folded edge, an adapter cylinder 2 inserted in an opening at the upper end of the end socket body 1, and a rubber sleeve 3 arranged at an opening at the lower end of the end socket body 1,

the 2 lateral walls of a switching section of thick bamboo are equipped with first clamp plate 4, first clamp plate 4 is located head body 1 inside, and the 4 lateral walls of first clamp plate set up with the 1 lateral wall of head body laminating arc surface mutually, 2 lateral wall covers of a switching section of thick bamboo are equipped with bush 5, bush 5 is located 1 upper end of head body, the lateral wall is equipped with second clamp plate 6, the 6 inside walls of second clamp plate set up with the 1 lateral wall of head body laminating arc surface mutually.

Preferably, the two ends of the inner side wall of the adapter cylinder 2 are both provided with a first sealing ring 7 near the opening.

Preferably, the bushing 5 is connected to the adapter 2 in a threaded rotation.

Preferably, the head body 1 is provided with reference column 8 for fixing the rubber sleeve 3 along the 1 hem of the head body, and the reference columns 8 are four in the equal distance along the 1 circumferential direction of the head body.

Preferably, the lateral wall of the positioning column 8 is sleeved with a second sealing ring 9, and the second sealing ring 9 is installed at two ends of the rubber sleeve 3 in an embedded mode.

Preferably, the side wall of the positioning column 8 is further sleeved with a nut 10 for locking the positioning column.

The utility model has the beneficial effects that:

through the cooperation that sets up gum cover, a switching section of thick bamboo and bush at head body both ends kneck and use, not only improved head body leakproofness, can also further increase the stability that the head body used.
