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.
Innovation and creation 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.
To achieve the goals above, the present invention provides it is a kind of tune flow pressure valve, comprising: valve casing, the valve casing have into
The mouth of a river and water outlet；Spool, the spool are mounted on inside the valve casing, and close to the water outlet, the spool includes

On shell；Filter, the filter are nested in valve bonnet, and close to the valve casing water inlet, the filter is connected to described
On valve seat.
Tune provided by the invention flows pressure valve, and the ceramic valve plate sealing surface grinding of spool, sealed precision is high, is using rotation
Axis adjusting is that torsional moment is smaller, convenient for adjusting；The filter for being placed in spool front end flows pressure valve itself to water heater and tune and plays
Good protective effect；The cleaning and replacement of filter are convenient in the configuration of valve bonnet.
According to one embodiment of present invention, the ceramic valve plate runoff investigation hole area gradually becomes with the rotation of rotation axis
Change.
In this embodiment, ceramic valve plate runoff investigation hole area is gradually changed with the rotation of rotation axis, i.e., ceramics are adjusted
Runoff investigation hole helically inclined-plane gradual change in stator is adjusted while being oriented to water flow with the rotation ceramics of rotation axis
Stator changes its section water amount.
According to one embodiment of present invention, ceramic valve plate is adjusted by the rotation axis, adjusts the rotation of water gradual change
Angle is greater than 220 degree.
In this embodiment, rotation axis adjusts ceramic valve plate, and the rotation angle of adjustment water flow gradual change is greater than 220 degree, in this way
When rotation axis adjusts ceramic valve plate, rotating angle range is larger, and ceramic valve plate can just be made to have enough distances on rotation perimeter
To adjust water inlet sectional area.
According to one embodiment of present invention, the valve bonnet is translucent, and the valve bonnet helps equipped with filter and tears hole open.
In this embodiment, valve bonnet is translucent, facilitates the observation to filter screen use state on filter, has served as filtering
When having accumulated more sundries on the net, that is, need to clean filter.It it is provided with filter on valve bonnet helps and tear hole open, since filter is installed
In valve bonnet, when valve bonnet is removed from valve casing, filter is not easy to take out out of valve bonnet, can tear hole open by helping using tool etc.
It is ejected.
According to one embodiment of present invention, the filter includes: supporting element, and the supporting element is mounted in valve bonnet,
The supporting element is equipped with O-ring mounting groove；Filter screen, the filter screen are cyclic annular entirety, are sleeved on the supporting element, and institute
The internal diameter for stating filter screen is greater than the support outer diameter of the supporting element.
In this example, filter includes supporting element and filter screen, and supporting element is mounted in valve bonnet, convenient for the whole of filter
Body disassembly, cleaning；It is convenient to be connected with filter screen equipped with O-ring mounting groove.Filter screen is that annular is whole, facilitates water from peripheral direction
Into increasing the discharge area of filter screen；Filtration net cover is on supporting element, and the internal diameter of filter screen is greater than supporting element
Outer diameter reduces the blocking that supporting element intakes to filter screen, increases into water area.
According to one embodiment of present invention, it is connected between the supporting element and the filter screen using O-ring.
In this example, it is connected between supporting element and filter screen using O-ring, filter screen is annular, the internal diameter of filter screen
Greater than the outer diameter of supporting element, O-ring can form uniform flexible radial support on the inside of filter screen between supporting element outer wall
Sealing.Impurity particle will not pass through from the fixation position of filter screen and supporting element.
According to one embodiment of present invention, the inner hole of the supporting element is connected with valve seat.The inner hole of supporting element with
Valve seat is connected, and is converged in supporting element inner hole by the water flow of strainer, imports valve seat via supporting element, hence into spool,
Water flow is set to form a guiding well, and the water for ensuring to flow through spool is to reduce impurity particle through filter screen filtration
Damage to spool, water heater, pressure release core.
