Description
Technical field
This utility model relates to a kind of water treatment part, specifically, relates to a kind of speed change for water process adjustable
Strainer head.
Background technology
Filter cap that filter in the market includes connecting the most successively, built-in fitting, filter bar, filter of the prior art
Head exists changes trouble, and resistance is big, the poor reliability that filter bar regulates in built-in fitting, and built-in fitting tightness on filter plate is poor,
The shortcomings such as recoil and water distribution gas distribution effect are bad, easy blocking.
Utility model content
For technical problem present in prior art, the purpose of this utility model is: provide one to have recoil very well
The adjustable strainer head of speed change of effect.
In order to achieve the above object, this utility model adopts the following technical scheme that
A kind of adjustable strainer head of speed change, including the filter cap connected the most successively, built-in fitting, filter bar, filter bar
The internal diameter of upper end is less than the internal diameter of lower end.
Preferred as one, filter bar internal diameter from top to bottom is gradually increased.
Preferred as one, filter bar is cone.
Preferred as one, coordinated by internal and external screw thread between filter cap and built-in fitting.
Preferred as one, external screw thread is positioned at the bottom of filter cap, and female thread is positioned at the top of built-in fitting.
Preferred as one, coordinated by internal and external screw thread between built-in fitting and filter bar.
Preferred as one, external screw thread is positioned at the top of filter bar, and female thread is positioned at the bottom of built-in fitting.
Preferred as one, the middle part of filter bar is provided with the turning handle being fixed by socket outside filter bar, the outer ring of turning handle
For hexagon.
Preferred as one, filter bar is provided with air inlet and air inlet seam.
Preferred as one, the top of built-in fitting is reverse frustoconic, and bottom is cylindrical；The outside of the bottom of built-in fitting sets
There are at least two group barb groups；Often group barb group all includes at least two barb, is arranged in zigzag with the barb of group.
Generally speaking, this utility model has the advantage that
1. filter bar uses the outlet reduced, and has the effect of water sprayer, can increase hydraulic pressure, improves jet velocity, strengthens and rinses
Intensity, repercussion effect is more preferable.
2., on the basis of there is fine repercussion effect, air inlet and air inlet seam are set simultaneously, make recoil and water distribution gas distribution
Effect is more preferable, is not easily blocked.
3. filter cap is coordinated by internal and external screw thread with built-in fitting, relative to directly with glue bonding or integrated poured side
Formula is easier to change filter cap, can change the filter cap in different gap as required.
4. built-in fitting and filter bar are coordinated by internal and external screw thread, relative to directly with glue bonding or integrated poured side
Formula is prone to adjust the height of filter bar.
5. tightening and unscrewing of the setting of turning handle, convenient filter bar and built-in fitting, increases frictional force.
6. using the structure organizing many barbs, built-in fitting tightness on filter plate is higher more.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
A kind of adjustable strainer head of speed change, including the filter cap connected the most successively, built-in fitting, filter bar.
The bottom of filter cap is provided with external screw thread.The filter cap in different gap can be selected as required.
The upper and lower of built-in fitting is equipped with female thread, and the female thread on top coordinates with filter cap, the female thread of bottom with
Filter bar coordinates.The top of built-in fitting is reverse frustoconic, and bottom is cylindrical；The outside of the bottom of built-in fitting is provided with at least two groups
Hook group, the present embodiment is two groups；Often group barb group all includes at least two barb, and the present embodiment is three, three barb arrangements
Toothing.
Filter bar is cone, and the internal diameter of the upper end therefore filtering bar is less than the internal diameter of lower end.Meanwhile, outside the upper end of filter bar is provided with
Screw thread, for coordinating with built-in fitting.The middle part of filter bar is provided with the turning handle being fixed by socket outside filter bar, the outer ring of turning handle
For hexagon.Filter bar is provided with the air inlet being located along the same line and air inlet seam.
In addition to the mode that the present embodiment is mentioned, filter bar can be the forge piece of step type structure being made up of several sections of cones, or is upper
Portion is conical structure and bottom is cylindrical structural, or is other structures in exit constriction, and these mapping modes all exist
In protection domain of the present utility model.
Above-described embodiment is utility model preferably embodiment, but embodiment of the present utility model is not by above-mentioned reality
Execute the restriction of example, other any without departing from the change made under spirit of the present utility model and principle, modify, substitute,
Combination, simplification, all should be the substitute mode of equivalence, within being included in protection domain of the present utility model.
