Before use, user accesses static balancing valve in the water pipe of pressure drop to be regulated, rotation hand wheel drives the first card
Rotation of the core in the first chuck, the registration of adjusting first through hole and the second through-hole, the space for keeping certain water supply stream to pass through,
In use, user's rotation hand wheel as needed, the second the core of the card are rotated synchronously with handwheel with the first the core of the card, the first chuck and second
Chuck structure is consistent, and the first the core of the card is consistent with the second the core of the card structure, at this point, user is by the second the core of the card of observation in the second chuck
Rotation and third through-hole and fourth hole registration, come directly judge rotation situation of first the core of the card in the first chuck,
With the registration of first through hole and the second through-hole, i.e., the size in space that water supply stream passes through adjusts water pipe to change water flow
Interior water flow pressure drop, wherein intuitively observe that the second the core of the card turns in the second chuck in user, first through hole is logical with second
When hole is completely coincident, water flow is maximum；Intuitively observe that the second the core of the card turns in the second chuck in user, first through hole with
When second through-hole is not overlapped angle, water flow is closed, and so on, coincidence angle is bigger, and water flow is bigger, is overlapped angle and gets over
Small, water flow is smaller.
The technical solution of the utility model is had been described in detail above with reference to the accompanying drawings, the technical solution of the utility model proposes
A kind of new static balancing valve only can drive the first the core of the card in the first chuck by the small-scale rotation of valve rod when in use
Interior rotation, so that it may change the size in the space that water supply stream passes through, it is time saving and energy saving, the leakproofness of valve is enhanced, and can utilize
The actual size of exposed the second chuck outside valve body and the more intuitive observation water flow aperture of the second the core of the card, effectively increases
The usage experience of user.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
