Abstract
The utility model relates to a pressure adjustable pressure valve structure, including the valve body, the valve body on be equipped with water inlet and delivery port water inlet department be provided with a pressure piston pressure piston and valve body between be equipped with fixed spring, fixed spring be located the pressure piston intermediate position the valve body on set up a plurality of evenly distributed's through -hole around the pressure piston in the middle of the through -hole in place regulating spring regulating spring's the through -hole of top in be equipped with the depression bar, the depression bar top be equipped with fixing device. After having adopted above -mentioned structure, press pressure piston through the depression bar with regulating spring on for fixed spring and regulating spring work together, and increased pressure conveniently adjusts, simple structure, convenient operation.
Description
Technical field
The utility model relates to a kind of valve arrangement in Machine Design manufacture field, especially relates to a kind of pressure valve structure of pressure adjustable.
Background technique
Pressure valve also becomes pressure controlled valve, mainly be used for satisfied with the power of actuator's proposition or the requirement of moment, along with industry ground development, pressure valve is widely used in every field, existing pressure valve mainly contains valve body, valve gap, valve disc and spring composition, when work, water flow pressure reaches required force value and backs down valve disc, valve disc Compress Spring, water is discharged, when force value reduces, valve disc blocks the passage in valve seat under the action of the spring again, and this pressure valve adopts fixing spring number to realize pressure valve constant voltage, a kind of pressure can only be controlled, when needing change at pressure, need the pressure valve adopting other force value different, such cost that will cause increases, inconvenient operation.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of can conveniently to the pressure valve structure of the pressure adjustable that pressure regulates.
The technical scheme in the invention for solving the technical problem is: a kind of pressure valve structure of pressure adjustable, comprise valve body, described valve body is provided with water intake and water outlet, described water inlet is provided with a pressure piston, fixing spring is provided with between described pressure piston and valve body, described fixing spring is positioned at pressure piston neutral position, described valve body offers some equally distributed through holes in the middle of pressure piston, Regulation spring is placed in described through hole, depression bar is provided with in through hole above described Regulation spring, described depression bar top is provided with fixing device.
Concrete further, described fixing device comprises the baffle plate be fixed on depression bar head and the limiting board being fixed on valve body top, and described limiting board is inverted " L " shape.
Concrete further, described depression bar head is provided with handle.
Concrete further, described fixing device comprises the outside thread be arranged on depression bar cylinder and the internal thread being arranged on through hole inside, described outside thread and screw-internal thread fit.
The beneficial effects of the utility model are: after have employed said structure, are pressed onto on pressure piston by depression bar by Regulation spring, fixing spring are worked together with Regulation spring, pressure increase, conveniently regulate, and structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, valve body; 2, water intake; 3, water outlet; 4, pressure piston; 5, fixing spring; 6, through hole; 7, Regulation spring; 8, depression bar; 9, baffle plate; 10, limiting board; 11, handle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A kind of pressure valve structure of pressure adjustable as shown in Figure 1, comprise valve body 1, described valve body 1 is provided with water intake 2 and water outlet 3, described water intake 2 place is provided with a pressure piston 4, fixing spring 5 is provided with between described pressure piston 4 and valve body 1, described fixing spring 5 is positioned at pressure piston 4 neutral position, described valve body 1 offers some equally distributed through holes 6 in the middle of pressure piston 4, Regulation spring 7 is placed in described through hole 6, depression bar 8 is provided with in through hole 6 above described Regulation spring 7, described depression bar 8 top is provided with fixing device, described fixing device comprises the baffle plate 9 be fixed on depression bar 8 head and the limiting board 10 being fixed on valve body 1 top, and described limiting board 10 is in inverted " L " shape, described depression bar 7 head is provided with handle 11.
When needing the pressure increasing pressure valve, depression bar 8 above valve body 1 is depressed, depression bar 8 promotes Regulation spring 7 and contacts with pressure piston 4, after depression bar 8 is pressed onto certain position, rotates depression bar 8, baffle plate 9 on depression bar 8 is coordinated with limiting board 10, realize fixing, now, fixing spring 5 works together with Regulation spring 7, the pressure of pressure valve increases, and can be combined by multiple depression bar 8 be as required fixed with Regulation spring 7.
The mode of another kind of fixing device is that described fixing device comprises the outside thread be arranged on depression bar 8 cylinder and the internal thread being arranged on through hole 6 inside, described outside thread and screw-internal thread fit.
Very easily Regulation spring 7 to be fixed on pressure piston 5 by coordinating of outside thread and internal thread.
Said structure is simple, easy to make, easy to use, and when needs force value is different, not needing to change pressure valve can reach requirement, applied widely.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
