Description
Technical field
The present invention relates to liquid handling device, especially a kind of liquid pressure regulator valve that can regulate water flow pressure size.
Background technique
Usually the pipeline of various function is provided with in liquid handling device, water flow pressure needed for each pipeline, current size may be different, or sometimes need for certain pipeline that water flow pressure is large, water flow is large, sometimes need again that water flow pressure is little, water flow is little, the existing mode arranging the current limliting button of different openings in the duct needs dismounting pipeline, replace corresponding current limliting button, and then assemble, operate convenient and swift not.
Summary of the invention
The technical problem solved: for the deficiencies in the prior art, the invention provides a kind of liquid pressure regulator valve, solves in prior art and there is dismounting technical problem not easily with the mode limiting pressure of current limliting button and current.
Technological scheme: for solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of liquid pressure regulator valve, comprise valve body, described body cavity is through, described body cavity is followed successively by the first cavity from top to bottom, second cavity and the 3rd cavity, the upper cover matched is provided with in described first cavity, the inner chamber of described upper cover is the through hole of one deck step, described through hole is up-small and down-big, the screw of coupling is provided with in the aperture on top, and screw lower end surface is provided with the first journal stirrup, describedly in the macropore through hole of bottom, be provided with valve rod, described valve rod comprises a stock, stock upper end is placed in screw inner chamber, stock lower end is provided with blind hole and columniform second journal stirrup of a circle, spring is provided with between described first journal stirrup and the second journal stirrup, be provided with spool in described blind hole, spool and blind hole interference fit, be positioned at the step place of the second cavity and the 3rd cavity after blind hole is stretched out in one end of spool and be connected with piston head, described piston head is greater than the under shed of the second cavity, described valve rod lower end is provided with tubular and crosses fluidization tower, and described spool passed fluidization tower, and on the small boss of overcurrent pylon on spool, described second cavity is connected with pressure gauge with side ducts,
Further, in the present invention, described screw and upper cover pass through screw-thread fit.Can pressure rotary screw Compress Spring as required, and then the gap between control piston head and the second cavity.
Further, in the present invention, rubber sheet gasket is provided with between described spool and mistake fluidization tower.The friction reducing valve rod and cross between fluidization tower
Further, in the present invention, water inlet pipe is connected to below described 3rd cavity.Current enter the 3rd cavity from sleep pipeline.
Beneficial effect: the present invention is engaged with upper cover by screw, the decrement controlling below spring, with the gap between regulating piston head and the second cavity, coordinates pressure gauge to control pressure and the flow of current.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
A kind of liquid pressure regulator valve, comprise valve body 1, described valve body 1 inner chamber is through, and described valve body 1 inner chamber is followed successively by the first cavity 2, second cavity 3 and the 3rd cavity 4 from top to bottom, is connected to water inlet pipe 15 below described 3rd cavity 4.
The upper cover 5 matched is provided with in described first cavity 2, the inner chamber of described upper cover 5 is the through hole of one deck step, described through hole is up-small and down-big, is provided with the screw 11 of coupling and screw 11 lower end surface is provided with the first journal stirrup in the aperture on top, and described screw 11 passes through screw-thread fit with upper cover 5.
Describedly in the macropore through hole of bottom, be provided with valve rod 6, described valve rod 6 comprises a stock 7, and stock 7 upper end is placed in screw 11 inner chamber, and stock 7 lower end is provided with blind hole and columniform second journal stirrup of a circle, is provided with spring 12 between described first journal stirrup and the second journal stirrup; Be provided with spool 10 in described blind hole, spool 10 and blind hole interference fit, be positioned at the step place of the second cavity 3 and the 3rd cavity 4 after blind hole is stretched out in one end of spool 10 and be connected with piston head 8, described piston head 8 is greater than the under shed of the second cavity 3; Described valve rod 1 lower end is provided with tubular and crosses fluidization tower 9, is provided with rubber sheet gasket 16, the friction reducing valve rod 6 and cross between fluidization tower 9 between described spool 10 and mistake fluidization tower 9.Described spool 10 passed fluidization tower 9, and crossed on the small boss of fluidization tower 9 frame on spool 10; Described second cavity 3 is connected with pressure gauge 14 with side ducts 13.
When pressure gauge 14 show pressure excessive time, rotated up by screw 11, reduce the gap between piston head 8 and the second cavity 3, water flow reduces, and pressure reduces then; Otherwise, when pressure gauge 14 show pressure too small time, be rotated down by screw 11, increase the gap between piston head 8 and the second cavity 3, water flow increases, and pressure is strengthened then.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
