Abstract
The invention provides an exhaust value structure capable of exhausting not supplying air. The exhaust value structure comprises a valve body, a valve plate, a spring, a supporting plate, a guide sleeve, a lower cover and a floating ball. The floating ball is arranged in a cavity below an exhaust port of the valve body, the hollow lower cover is fixed above the exhaust port, the guide sleeve and the valve plate are placed above the lower cover, the valve plate is arranged in the guide sleeve, the supporting plate is arranged above the guide sleeve, one end of the spring is fixed on the valve plate, the other end of the spring is fixed on the lower surface of the supporting plate, the upper surface of the lower cover is provided with an annular protrusion, wherein the cross section of the annular protrusion is a triangle, and the annular protrusion contacts the lower surface of the valve plate. The exhaust value structure has the advantages that air can be discharged out of the valve body, air and other media can not enter into the valve body through the exhaust port, and the exhaust value structure is suitable for various occasions without need of air supply.
Description
Technical field
The present invention relates to a kind of exhaust structure, especially relate to the exhaust structure that a kind of exhaust can not tonifying Qi.
Background technique
Outlet valve is applied to the pipeline air exhaust waters such as large-scale water transport pipeline, pumping plant, independent heating system, central heating system, heating boiler, central air-conditioner, floor heating and solar heating system usually.When not intaking in order to prevent that extraneous gas from entering from relief opening, generally all can be with valve closing.But under certain operating conditions, current are regular needs to cut off, and in order to prevent the relief opening tonifying Qi, what just needs were regular carries out opening and closing to outlet valve, very inconvenient.
Summary of the invention
The purpose of this invention is to provide the exhaust structure that a kind of simple in structure, safe and reliable exhaust can not tonifying Qi.
technological scheme of the present invention is: the exhaust structure that a kind of exhaust can not tonifying Qi, comprise valve body, valve plate, spring, dunnage, guide sleeve, lower cover and ball float, described ball float is positioned at the cavity of the relief opening below of described valve body, described relief opening top is fixed with the described lower cover of hollow, the top of described lower cover is placed with described guide sleeve and described valve plate, described valve plate is positioned in described guide sleeve, described dunnage is placed in above described guide sleeve, described spring one end is fixed on described valve plate, one end is fixed on the lower surface of described dunnage, it is leg-of-mutton annular protrusion that the upper surface of described lower cover has a cross section, described annular protrusion contacts with the lower surface of described valve plate.
Preferably, also comprise upper cover, described upper cover is positioned at above described dunnage.
Preferably, also comprise interstage sleeve and seal ring, described interstage sleeve and seal ring are arranged between described lower cover and described relief opening.
Preferably, the bottom of described guide sleeve has several breach.
Preferably, be provided with for the groove of fixing described spring in the middle part of described dunnage.
Preferably, described valve plate is provided with the boss that blocks spring.
Advantage and good effect that the present invention has are:
Owing to adopting technique scheme, when in pipeline, gas being arranged, gas pressure can back down valve plate, thereby guarantees that the gas expulsion valve is external.When negative pressure appears in pipeline, water level descends, ball float can leave seal ring under Action of Gravity Field, open relief opening, valve plate can be close under spring force and self gravitation effect on the circular protrusion sealing surface of lower cover, the sealing relief opening guarantees that gas or other media can not enter in valve body by relief opening, are fit to the occasion of various not needs tonifying Qi.

Embodiment
The invention will be further described below in conjunction with the drawings and the specific embodiments.
as depicted in figs. 1 and 2, the present invention includes valve body 10, valve plate 1, spring 2, dunnage 3, guide sleeve 4, upper cover 5, lower cover 6, interstage sleeve 7, seal ring 8 and ball float 9, described ball float 9 is positioned at the cavity of the relief opening below of described valve body 10, described relief opening top is fixed with the described lower cover 6 of hollow, described interstage sleeve 7 and seal ring 8 are arranged between described lower cover 6 and described relief opening, the top of described lower cover 6 is placed with described guide sleeve 4 and described valve plate 1, described valve plate 1 is positioned in described guide sleeve 4, described dunnage 3 is placed in described guide sleeve 4 tops, described spring 2 one ends are stuck on the boss of described valve plate 1, one end is fixed in the groove of lower surface of described dunnage 3, it is leg-of-mutton annular protrusion that the upper surface of described lower cover 6 has a cross section, described annular protrusion contacts with the lower surface of described valve plate 1, described upper cover 5 is positioned at described dunnage 3 tops, the bottom of described guide sleeve 4 has several breach.
During use, when in pipeline, gas being arranged, gas pressure can back down valve plate 1, thereby guarantees outside gas discharge valve body 10.When negative pressure appears in pipeline, water level descends, ball float 9 can leave seal ring 8 under Action of Gravity Field, open relief opening, valve plate 1 can be close under spring force and self gravitation effect on the circular protrusion sealing surface of lower cover 6, the sealing relief opening guarantees that gas or other media can not enter in valve body 10 by relief opening, are fit to the occasion of various not needs tonifying Qi.
Above embodiment has been described in detail the present invention, but described content is only preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., within all should still belonging to patent covering scope of the present invention.
