The low-resistance direct-flowing type hydraulic control valve has the beneficial effects that: the low-resistance direct-flowing type hydraulic control valve provided by the utility model has the advantages of multiple functions, small resistance loss, large flow and the like, the valve core is a fixed type valve core, and the opening and closing of the valve are realized by driving the membrane under the pressure of the pipeline, thereby achieving the closing function; and the low-resistance direct-flowing type hydraulic control valve cannot be worn, is high in automation degree, greatly prolongs the service life of the valve, is energy-saving and environment-friendly, and is convenient to repair.
Description
Technical field
The utility model relates to a kind of lower resistance once-through type hydraulic control valve.
Background technique
Lower resistance once-through type multi-functional water power control valve is a kind of novel hydropower control valve, is widely used in feedwater in industrial and mineral, civil building, the energy-conservation irrigation of fire-fighting as regulating the functions such as pressure, flow and water level.Various combinations such as the external all kinds of pilot valves of main valve, pipe arrangement accessory and reach various functions and control object.Existing valve function is single, drag losses is large, flow is little, spool is combined type spool, fragile, easy to wear, automaticity is low, valve working life is short, maintenance difficult.
Model utility content
The purpose of this utility model is to provide a kind of lower resistance once-through type hydraulic control valve, to overcome existing above-mentioned deficiency at present.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of lower resistance once-through type hydraulic control valve; comprise valve body; described valve body front portion is provided with platen one; valve body rear portion is provided with platen two; described valve inner is provided with barrier film; described barrier film inside is inserted with fixed spool, and described barrier film two ends recess is separately installed with overpressure protection support one and overpressure protection support two, and described fixed spool, overpressure protection support one and overpressure protection support two inside are inserted with valve shaft.
Preferably, described platen one is fixedly connected with valve body by several screw rods with platen two.
Further, described fixed spool front end and overpressure protection support one joint, rear end are provided with rubber ring.
Further, described valve shaft front end sleeve has pad one, and valve shaft and overpressure protection support one are fixing by nut one.
Further, valve shaft rear end cover has pad two, and valve shaft and overpressure protection support two are fixing by nut two.
The beneficial effect of model utility is: a kind of lower resistance once-through type hydraulic control valve that the utility model provides, the keying that function is many, drag losses is little, large flow, spool are fixed spool, valve by self pressure-driven barrier film of pipeline reach closing function, do not have any abrasion condition, automaticity is high, greatly improved the advantage such as working life, energy-conserving and environment-protective, convenient for maintaining of valve.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the plan view of a kind of lower resistance once-through type hydraulic control valve described in the utility model embodiment;
Fig. 2 is the decomposing schematic representation of a kind of lower resistance once-through type hydraulic control valve described in the utility model embodiment;
Fig. 3 is the section of a kind of lower resistance once-through type hydraulic control valve described in the utility model embodiment.
In figure:
1, valve body; 2, platen one; 3, platen two; 4, screw rod; 5, barrier film; 6, fixed spool; 7, valve shaft; 8, overpressure protection support one; 9, overpressure protection support two; 10, rubber ring; 11, pad one; 12, nut one; 13, pad two; 14, nut two.
Embodiment
As Figure 1-3; a kind of lower resistance once-through type hydraulic control valve described in the utility model embodiment; comprise valve body 1; described valve body 1 front portion is provided with platen 1; valve body 1 rear portion is provided with platen 23, and valve body 1 inside is provided with barrier film 5, and barrier film 5 inside are inserted with fixed spool 6; barrier film 5 two ends recess are separately installed with overpressure protection support 1 and overpressure protection support 29, and fixed spool 6, overpressure protection support 1 and overpressure protection support 29 inside are inserted with valve shaft 7.Described platen 1 is fixedly connected with valve body 1 by several screw rods 4 with platen 23; described fixed spool 6 front ends and overpressure protection support one 8 joints, rear end are provided with rubber ring 10; described valve shaft 7 front end sleeves have pad 1; valve shaft 7 is fixing by nut 1 with overpressure protection support 1; valve shaft 7 rear end covers have pad 2 13, and valve shaft 7 is fixing by nut 2 14 with overpressure protection support 29.
A kind of lower resistance once-through type hydraulic control valve described in the utility model embodiment, before starting mode of pump, valve export end pressure acts in valve body 1 pressure chamber, and valve is in closed condition, valve body 1 pressure chamber water outlet simultaneously communicates with high voltage terminal, and cavity of resorption communicates with the low pressure of valve inlet end; After starting mode of pump, valve inlet pressure raises gradually, and main valve pressure chamber is slowly discharged into downstream by the connecting tube of valve export end by valve pocket pressure simultaneously, realizes the slow unlatching of valve body 1 barrier film 5, and opening speed can regulate by micro-control valve; Water pump is shut down, and the pressure decreased of valve inlet end, when approaching zero delivery, in the rapid valve body 1 of effect lower diaphragm plate 5 of waterpower.Because valve inlet end pressure reduces, the press water of valve export end enters in valve body 1 pressure chamber by connecting tube, and valve body is closed.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, within all dropping on protection domain of the present utility model.
