Abstract
The utility model relates to an automatic exhaust valve with support points. Inner threads at the upper part of a shell body are connected with outer threads at the lower part of an upper cover. An inner threaded hole which is connected with an exhaust hole through threads is arranged in the middle part of the upper cover. The edge of an exhaust nozzle of the inner threaded hole is movably connected with a floating rod. A floating ball is arranged in the shell body and is connected with the floating rod through the threads. The support points for supporting the floating ball are arranged at the bottom of the shell body, which are placed in a triangle shape or symmetrically in a quadrangle shape or in a pentagon shape. The support points are in a parabola shape or an oval shape and are used for holding the floating ball. Because the structure is simplified and improved, the utility model has simple structure, is convenient to dismantle and hardly generates impurities and dirt after long-period work. The floating ball has better stability and hardly deviates.
Description
Technical field
The utility model relates to the automatic control pressure vent door device of using on a kind of domestic heating pipe-line system, particularly a kind of automatic control pressure vent with the strong point.
Background technique
At present, known as China Patent No.: the disclosed a kind of outlet valve of 02280741.1 and 200320112523.2 utility model patents with isolating frame, housing bottom is provided with a projection, in order to ball float and housing bottom are kept apart, its drawback is that the ball float poor stability departs from easily; Because of ball float with float bar for being threaded, the housing inner bottom part is provided with a strong point, causes ball float to come off easily and floats bar, and outlet valve can not effectively be worked, thus the potential safety hazard of causing.
Summary of the invention
At the deficiency that above-mentioned technical problem exists, the purpose of this utility model provides a kind of automatic control pressure vent with the strong point.
The technical solution of the utility model is as follows:
A kind of automatic control pressure vent with the strong point, comprise the internal thread on housing top and the external thread bolt connection of loam cake bottom, on cover the middle part and be provided with the interior threaded hole of the exhaust port that is spirally connected, the limit portion of its exhaust port with float bar and flexibly connect, in housing, be provided with ball float, ball float with float bar and be spirally connected.Be provided with the strong point of putting that is used to support ball float triangular in shape at housing bottom; Or be the strong point that is used to support ball float that tetragonal symmetry is put; Or be the strong point that is used to support ball float that pentagon is put; It is parabola shaped or oval that the described strong point is, and is used for ball float is held up.
Be welded with valve seat in lower housing portion, valve seat and pipeline are spirally connected, and are provided with at the housing inner bottom part and are used for preventing the filter screen that impurity enters.
Be provided with the plural at least strong point at the housing inner bottom part, have the effect that makes ball float more firm than a strong point is set.
Described filter screen is made of stainless steel, and its filter screen outer installment has limit portion.
The utility model has been because of having carried out the summary improvement in configuration aspects, has simple in structurely, and convenient disassembly under situation about working long hours, is difficult for producing impurity and dirt.The ball float good stability is not easy to depart from.
