Abstract
The utility model relates to a high-pressure water spray head. A stop valve is arranged in a rectifier pipe and is provided with a reverse thrust spring device; a water inlet of a filter hood is groove-shaped, the grooving directions are parallel with the axial line of the filter hood, grooves are distributed on the filter hood, and the stop valve is a cone; and a water outlet of the filter hood is trumpet-shaped. The high-pressure water spray head has small influence on water flow, which reduces the turbulence degree of the water flow; and the opening and closing pressure for the stop valve is about 1.0 MPa, when the water pressure in a collector pipe is more than 1 MPa, the stop valve is opened and the high-pressure water spray head starts spraying water, on the contrary, the high-pressure water spray head does not spray water, thus the water quantity is controlled well and more energy can be saved.
Description
Affiliated technical field
The utility model relates to a kind of hydraulic spray.
Background technology
Hydraulic spray is the critical piece that forms high-pressure spray, and water under high pressure is through obtaining our required jet shape (cylindricality or fan-shaped) after it.Owing to may contain impurity and the plug nozzle head in the fluid, therefore, on nozzle, be provided with filter mantle, in order to filter the impurity that comprises in the fluid, but the opening on traditional filter mantle is to be horizontally installed on (being that the water inlet opening direction is axially vertical with filter mantle) on the filter mantle, this set can increase the turbulence level of high-pressure fluid, hinders the flow direction of fluid, has had influence on the optimum efficiency of jet equally.
When hydraulic spray used on milling train, traditional working method was: when the needs de-scaling, logical water under high pressure in the high pressure collector pipe is not when needing de-scaling, in the logical low-pressure water of high pressure collector pipe, to guarantee being full of water all the time in the collector pipe, with the protection collector pipe.But when the thin plate of rolling some steel grade, wish that the water yield that is sprayed onto on the steel billet minimizes, to improve the quality of rolled piece, traditional like this high pressure nozzle just can not meet the demands.
The utility model content
In order to address the above problem, this practicality provides a kind of can filter out the impurity that contains in the water, can not hinder flow direction again, also can not have influence on the jet effect, simultaneously the hydraulic spray design of problem that also can fine control nozzle water yield.
The technical scheme that its technical problem that solves the utility model adopts is:
The utility model mainly comprises water inlet (1), the composition on nozzle head (6), rectifier (3), filter mantle (2) and the filter mantle, and it also is provided with stop valve (7) in the rectifier pipeline; Stop valve is provided with the anti-spring assembly (8) that pushes away; Its opening of described water inlet (1) is a strip, is distributed on the filter mantle (2).Described stop valve is a cone, and filter mantle delivery port (4) is horn-like, and stop valve (7) matches with filter mantle delivery port (4) can form sealing.Described water inlet (1) is the groove shape, and the fluting trend is parallel with the filter mantle axis.
The beneficial effects of the utility model are: because the water inlet opening direction is consistent with the direction of current, the obstruction of current is influenced little, reduced the turbulence level of current; The engaging pressure of stop valve is about 1.0Mpa, and when the hydraulic pressure in the collector pipe during greater than 1Mpa, stop valve is opened, and hydraulic spray begins water spray, otherwise does not then spray water, the problem of hypervolia when having solved rolled sheet metal well, also energy savings more.
Description of drawings
Fig. 1 is the installation diagram of high pressure water jets mouth structure;
Fig. 2 is that filter mantle is analysed and observe; The stop valve scheme of installation;
Fig. 3 is the filter mantle upward view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.The technical scheme that its technical problem that solves the utility model adopts is:
Because the water inlet opening direction is axially, and is consistent with the direction of current, little to the obstruction influence of current, reduced the turbulence level of current;
The engaging pressure of stop valve (7) is about 1.0Mpa; when hydraulic spray uses on milling train; traditional working method is: when the needs de-scaling; logical water under high pressure in the high pressure collector pipe; when not needing de-scaling; in the logical low-pressure water of high pressure collector pipe, to guarantee being full of water all the time in the collector pipe, with the protection collector pipe.But when the thin plate of rolling some steel grade, when the hydraulic pressure in the collector pipe during greater than 1Mpa, hydraulic pressure is greater than the anti-tension force that pushes away spring assembly (8), and stop valve is opened, and hydraulic spray begins water spray, otherwise does not then spray water.
In conjunction with the accompanying drawings the specific embodiment of the present utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
