Description
Technical field
The present invention relates to a kind of valve bodies.Pressure valve is flowed in particular to a kind of tune.
Background technique
Existing water heater flows pressure valve with tune and is mounted on heater inleting pipe, and user wants in normal use water
It flows through tune and flows pressure valve and enter water heater.Tune flows pressure valve by its tunable characteristic, can tune up or turn down water flow to meet use
Family demand.When machine is more than relief valve nominal pressure, extra pressure is released by relief hole.
Currently, first kind tune flows pressure valve, adjusted using copper axis, but when not turning for a long time, it may appear that copper is embroidered it
Block, thus can not regulating pondage, influence user and comfortably experience.
Second class tune flows pressure valve, and using ceramic valve plate, but adjustable-angle is smaller, causes water fine adjustment extremely not square
Just.
And it adjusts and flows pressure valve without filtering function, when using water heater gasket type filter screen, filter area extremely has
Limit, and it is not easy to disassembly, cleaning.If filter screen mesh number is smaller, to water heater, adjusts and flow the harmful particle of pressure valve and can pass through
Filter screen；If filter screen mesh number is big, possibly filtering out net will soon be blocked, and water flow be influenced, to influence user experience.
Utility model content
In order to solve the above-mentioned technical problem at least one, the purpose of the present invention is to provide a kind of structurally reasonable, and can be more
Effective protection water heater and the tune of itself function flow pressure valve.
