Embodiment:
As shown in attached drawing 1 to attached drawing 5:
The utility model provides a kind of water pump that sealing effect is good, includes: the pump housing 1, water inlet 2, water outlet 3, outer spiral shell
Line section 4, mounting ring 5, reinforcing ring 6, casting die 7, hold-down bolt 8, thread bush 9, sealing ring 10 and floor 11；The pump housing 1 or so
The external thread section 4 of a small distance is also provided on the water inlet 2 of two sides and the tube wall of water outlet 3, by this this it is a bit of
External screw thread is respectively cooperating with the mounting ring 5 of annular slab structure at one；The mounting ring 5, medial surface uniformly put that be welded with a circle multiple
The casting die 7 of box-like structure, and the annular extent size where these casting dies 7 is greater than the excircle configuration ruler of water inlet 2 or water outlet 3
It is very little；The outer end face of the water inlet 2 and water outlet 3 is also provided with annular groove, and it is close to be also inlaid with a circle in a ring groove
Seal ring 10.
Wherein: the casting die 7 is U-shaped part made of sheet metal bending, their U-shaped is intracavitary, and also point is welded with a piece of floor
11, structure is described herein as shown in figure 5, will receive certain extruding force when casting die 7 acts on, and the setting of floor 11, it can make to press
The intensity of part 7 is strengthened, structurally reasonable.
Wherein: the reinforcing ring 6 is also annular slab structure, and tiling point is welded on the lateral surface of casting die 7, makes a circle casting die
7 form unified annular connection, are described herein as structure as shown in figure 5, can make the root of this circle casting die 7 using this reinforcing ring 6
Strengthened fixation, and root is deformed when preventing 7 stress of casting die from squeezing work.
Wherein: the casting die 7 inwardly also extends through from top and is welded with a thread bush 9, and passes through this root thread bush 9
Hold-down bolt 8 at one have also been threadedly engaged, hold-down bolt 8 is the core working plate of casting die 7, when they are by the movement of stubborn power is turned,
Root pushes, to press on the outer end face for the outer water tube flange-interface that pump housing flange-interface is connected, make external interface with
The water inlet gap of this structure obtains pressure compensation, reduces interface and leaks the probability happened.
Wherein: the bottom end of the hold-down bolt 8 is the frustum structure of large area active force, and these 8 bottoms of hold-down bolt
Position where face is corresponding with the position where sealing ring 10, is described herein as structure as shown in figure 3, hold-down bolt 8 is by turning to twist
When power spinning movement, root is pushed, and makes outer water tube flange-interface is synchronous with the formation of sealing ring 10 to squeeze, sealing ring 10 acts on
At pump housing nozzle and outer water tube spout interface, even closer sealing effect is carried out, pump housing ferrule structure is further proposed
Reasonability.
When use: the water inlet 2 or water outlet 3 of this structure are docked with outer water tube flange-interface by the fixation of general bolt
After use, by rotatably compressing bolt 8, hold-down bolt 8 is set to press to the left, so that outer water tube flange-interface be made to continue close to pump
Body nozzle, which forces, to be squeezed, and the gap so as to further generate nozzle junction is compensated for, if in use process, still there is water
When slime flux goes out, hold-down bolt 8 can be adjusted again, and hold-down bolt 8 inwardly continues to press, and the synchronous sealed of sealing ring 10 is cooperated to make
With the two sets of pressing devices that can equally solve hydraulic overflow problem, and be installed on water inlet 2 or water outlet 3 pass through external thread section
4 adjustable axial positions, therefore there is preferable flexible practicability, it can be adjusted according to the wall thickness of external water pipe flange-interface
Installation.
The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustively or to incite somebody to action
The utility model is limited to disclosed form.Many modifications and variations are aobvious and easy for the ordinary skill in the art
See.Embodiment was chosen and described in order to better illustrate the principle and practical application of the utility model, and makes this field
