Description
Technical field
The present invention relates to valve, a kind of gravity one-way cock is related in particular to.
Background technology
Valve is the control unit in fluid delivery system, with cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the function such as overflow pressure relief.Check valve is also known as check-valves, and check valve belongs to a kind of automatic valve, and its effect is prevented in pipeline
Medium flows backwards.For the valve of fluid control systems, from simplest check valve into extremely complex robot control system(RCS) it is used
Various valves, its kind and specification are quite various.Check valve is generally in normally open in normal conditions.Gravity check valve is
Realize that valve body is closed and cut-out pipeline by self gravitation effect, compared to magnetic valve, with low cost and other advantages simple in construction, but
Purposes is single.The free-piston (or piston sheet) of gravity check valve, is all to be wrapped in inside by valve housing, will in zero load
Open valve, only gravity one-way valve piston be inverted come could open, do not influence produce during fluid sources
Head carries out pressure regulation or release, and prior art gravity check valve is had no way of doing it at all.
In process of production, fluid sources head to be controlled, do not require nothing more than that gravity one-way cock is simple in construction, make sometimes
Valency is low, by flow it is big, can non-return, do not leak, can acid-alkali-corrosive-resisting, more require can indirectly fluid sources head to carry out pressure regulation steady
Pressure, can open valve fluid sources head and carry out release.
It can not search for the product for conforming to above-mentioned requirements on the net.Patent retrieval is carried out, the patent application being closer to is searched
A kind of number 201420644951.8 gravity check valves, it is disclosed in correspondence feed tube inclined-plane on housing and sets a gravity cover plate, weight
The top of power cover plate is fetched with valve body door bolt reaches gravity non-return purpose.Obviously, above-mentioned requirements are not conformed to.
