Abstract
The utility model provides a kind of high-pressure spray pipe, and the inwall of body is provided with two screw-shaped thorax lines protruding, two thorax line projections are oppositely arranged; The pitch of thorax line projection is greater than the internal diameter of five times of bodys; The height of thorax line projection is between 10 to ten/20th 1/5th of the internal diameter of body.The rotatable injection of the utility model current, thus more stable, more not easily disperse, can not disperse apart from interior maintenance collected state longer after therefore penetrating the mouth of pipe; Unit area hydraulic pressure can not excessively improve, thus largely avoid some risks in use; Fixed block arranges that can ensure under fixed condition can Long-Time Service, and without the need to worrying that the centrifugal force in water flow rotary process impacts the stable of body.
Description
Technical field
The utility model relates to a kind of high-pressure spray pipe, belongs to plastic pipes.
Background technique
In prior art, the water of high-pressure water pipe injection often very disperses, for this reason when needs current are concentrated and penetrated far away, often need to install tap additional, to improve the initial velocity of water-jet outlet spout, but so also mean that the recoil force of tap can be very large, and the initial velocity of water improves, unit area hydraulic pressure also improves, and is difficult to the risk avoided during some will inevitably be caused like this to use thereupon.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of high-pressure spray pipe, this high-pressure spray pipe is by the setting of thorax line projection, effectively ensure that the current injection mouth of pipe can keep collected state within the longer time, thus ensure that the current concentrated can be outranged, and do not have too high the brought risk of unit area hydraulic pressure.
The utility model is achieved by the following technical programs.
A kind of high-pressure spray pipe that the utility model provides, the inwall of body is provided with two screw-shaped thorax lines protruding, two thorax line projections are oppositely arranged; The pitch of thorax line projection is greater than the internal diameter of five times of bodys; The height of thorax line projection is between 10 to ten/20th 1/5th of the internal diameter of body.
At least one group of fixed block described body be equipped with; Each group fixed block is more than four, and the outside diameter hoop along body is uniformly distributed; Each fixed block in each group fixed block is being zero along the axial distance of body.
The cross section of described thorax line projection is triangle, itself and the reverse edge lengths of hand of spiral are three times to five times with a hand of spiral edge lengths in the same way, and and between hand of spiral place straight line in the same way and the round tangent line being tangential on described body angle be 80 ° ~ 110 °.
The semiellipsoid of described fixed block to be cross section be right-angled triangle, the right angle side of right-angled triangle, towards one end of body, fixed block has been horizontally disposed with screw.
The structure that described body, thorax line are protruding, fixed block is formed in one.
The beneficial effects of the utility model are: the 1. rotatable injection of current, thus more stable, more not easily disperse, and can not disperse after therefore penetrating the mouth of pipe longer apart from interior maintenance collected state; 2. unit area hydraulic pressure can not excessively improve, thus largely avoid some risks in use; 3. fixed block arranges that can ensure under fixed condition can Long-Time Service, and without the need to worrying that the centrifugal force in water flow rotary process impacts the stable of body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the close-up sectional view of Fig. 1;
In figure: 1-body, 2-thorax line is protruding, 3-fixed block.
Embodiment
Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.
A kind of high-pressure spray pipe as shown in Figure 1 to Figure 3, the inwall of body 1 is provided with two screw-shaped thorax line projections, 2, two thorax line projections 2 and is oppositely arranged; The pitch of thorax line projection 2 is greater than the internal diameter of five times of bodys 1; The height of thorax line projection 2 is between 10 to ten/20th 1/5th of the internal diameter of body 1.
Arrange thus, current can the rotation from outside to inside because of the spiral of thorax line projection 2 in pipe, thus forms the rotary water current injection mouth of pipe, and current, to penetrate mouth of pipe rear stability high, can be outranged.Article two, thorax line projection 2 is oppositely arranged and can ensures body 1 stability in the course of the work to a great extent, and the setting of the pitch of thorax line projection 2 and height, then when taking into full account flow characteristics, through the most suitable result of testing in a large number and obtain after modeling Simulation, its concrete numeral also should be determined according to factors such as fluid density, pumping pressure, inlet pipe initial velocity.
Described body 1 is equipped with at least one group of fixed block 3; Each group fixed block 3 is more than four, and the outside diameter hoop along body 1 is uniformly distributed; Each fixed block 3 in each group fixed block 3 is being zero along the axial distance of body 1.
Equally distributed setting, is mainly mean allocation centrifugal force, thus ensures, in the long-term fixing process used, to cause displacement or the distortion of body 1 because of rocking of body 1, and body 1 is stressed also even simultaneously, thus the possibility of breaking is less.
The cross section of described thorax line projection 2 is triangle, itself and the reverse edge lengths of hand of spiral are three times to five times with a hand of spiral edge lengths in the same way, and and between hand of spiral place straight line in the same way and the round tangent line being tangential on described body 1 angle be 80 ° ~ 110 °.
Arrange thus, can ensure that thorax line projection 2 is causing the effect in water flow rotary further.
Described fixed block 3 for cross section be the semiellipsoid of right-angled triangle, a right angle side of right-angled triangle is towards one end of body 1, and another right angle side is that base is incorporated into body 1, and fixed block 3 has been horizontally disposed with screw.
Arrange thus, fixed effect can be ensured further.
The structure that described body 1, thorax line projection 2, fixed block 3 are formed in one.Avoid the generation of the situations such as tube wall explosion thus further.
