Abstract
An adjustable reducing valve with high sensitivity belongs to the valve field and solves the problems of the prior reducing valves, such as difficult manufacture, complex structure, poor sensitivity, small pressure reducing ratio, poor sealing, easily caused leakage and easy blockage. The adjustable reducing valve is provided. A gland bush is positioned at the bottom end of a valve body and nested in the valve body; the gland bush is fixedly connected with the valve body; the bottom end of a valve clack is nested in the top end of a hollow cavity of a bottom cover; a valve rod is connected with a pressure lever as a whole and penetrates the center of the valve body; the bottom end of the valve rod is connected with the valve clack; the top end of the pressure lever contacts a membrane; a cylindrical helical compression spring is positioned in a hollow cavity formed by the valve clack and the bottom cover; a top cover is positioned on the top end of the valve body; a hollow cavity is formed in the top cover; an adjusting spring is arranged in the hollow cavity; a pressure plate is positioned between the adjusting spring and the top cover; and a lower tray is positioned at the bottom end of the top cover and contacts the adjusting spring. The adjusting reducing valve has the advantages of easy manufacture, simple structure, large pressure reducing ratio, good sealability, little possibility of leakage and high sensitivity.
Description
Technical field
The utility model relates to a kind of high sensitivity adjustable compression release valve, belongs to valve field.
Background technique
The reduction valve of prior art has two kinds basically, a kind of is that the aperture size that will open the primary valve under the main valve plug through the valve vertebra of the spool of main valve and pilot valve by spring pressurized size from the MEDIA FLOW of import makes the mode of pressure stability regulate pressure, another kind is to make high-pressure medium flow into the import of the valve that has piston, diaphragm and major-minor flap, act on pressure difference and the upright equilibrium relation of spring that the area difference is constituted on these parts by medium, regulate the flap openings of sizes, regulate pressure.But the valve rod of these valves and flap are essentially one, make difficulty, complex structure, and poor sensitivity, Pressure reducing ratio is little, and the flap top is arc or projection, and it is poor to seal, and causes leakage easily, and stops up easily.
The model utility content
Make difficulty in order to overcome existing reduction valve, complex structure, poor sensitivity, Pressure reducing ratio is little, it is poor to seal, cause leakage easily, and the deficiency of stopping up easily, the purpose of this utility model is: provide a kind of easy to manufacture, simple in structure, Pressure reducing ratio is big, good airproof performance, the high sensitivity adjustable compression release valve that is not easy to leak.
The technological scheme that its technical problem that solves the utility model adopts is as follows:
The high sensitivity adjustable compression release valve, comprise gland, cylindroid helicalcoil compression spring, valve body, flap, valve rod, depression bar, diaphragm, following pallet, top cover, Regulation spring, pressing plate, limit screw cap, gland is positioned at the valve body bottom, nested with valve body, fixedly connected, the bottom of flap is nested in the cavity top of bottom, valve rod and depression bar connect as one, pass the valve body center, the valve rod bottom is connected with flap, and the depression bar top contacts with diaphragm, cylindroid helicalcoil compression spring is positioned at the cavity of flap and bottom formation, top cover is positioned at the valve body top, and cavity is arranged in the top cover, and Regulation spring is positioned at cavity, pressing plate is between Regulation spring and top cover, following pallet is positioned at the top cover bottom, contacts with Regulation spring, and diaphragm is between depression bar top and following tray bottom surface.
Also comprise safety helmet, safety helmet is nested in the top cover top.
Also comprise adjusting screw, adjusting screw is arranged in the cavity of safety helmet, penetrates the top cover top, contacts with pressing plate.
Also comprise limit screw cap, limit screw cap is nested on the adjusting screw, is positioned at the top cover top.
Also comprise set screw, pass the top cover edge, be fixed on the valve body for hexagonal in the M 8.
Compared with prior art, the beneficial effects of the utility model are:
1, be applicable to steam, liquid, gas, except that oxygen.
2, Pressure reducing ratio is big, and maximum can reach 10: 1.
3, simple in structure, easy to process.
4, valve rod, flap adopt separated type, effectively prevent stuck phenomenon.
5, flap adopts plane sealing, and processing is simple, and leakage rate is little, prevents the waste of resource effectively.
6, pressure directly feeds back part employing stainless steel diaphragm, and is highly sensitive.
7, be mainly used in the occasion that pressure is low, bore is little.
8, direct acting type replaces the small-bore occasion of guided piston type, prevents from effectively to stop up, straight-through phenomenon.
