Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides an exhaust valve.

In this embodiment, referring to fig. 1 to 2, this exhaust valve includes valve body 1, valve gap 2 and floater 3, valve gap 2 links firmly with valve body 1 through the bolt, valve gap 2 on be equipped with exhaust nozzle 4, be equipped with exhaust hole 5 on the exhaust nozzle 4, the valve body bottom is equipped with water inlet 6, water inlet 6 internal fixation has fixing base 7, be equipped with uide bushing 8 on the fixing base, the pole 19 activity of floating of floater upper end stretches into the exhaust hole, and the pole 19 activity of floating the floater lower extreme stretches into the guiding hole 9 of uide bushing, the bottom of exhaust nozzle is equipped with extension sleeve 10, be equipped with the through-hole 11 with the guiding hole coaxial line in the extension sleeve 10, be equipped with a plurality of bleeder vents 12 on the telescopic outer wall of extension, the pole top still is located the extension sleeve when the floater reaches the maximum distance.

Among the above-mentioned technical scheme, through set up the extension sleeve on the exhaust nozzle, when exhausting, make float the pole remain in the extension sleeve all the time to effectively avoid appearing because float the pole slope and can't aim at the exhaust hole and lead to closing the problem of failure, improved the stability of valve greatly. In addition, the air holes are formed in the extension sleeve for exhausting air, so that the air can be exhausted even if the floating rod is blocked in the extension sleeve.

Specifically, the diameter of the through hole is larger than that of the exhaust hole. The structure increases the clearance between the floating rod and the inner wall of the extension sleeve, improves the air displacement and avoids the blockage problem.
