Description
Technical field
This utility model relates to a kind of pressure-control valve, is specifically related to a kind of adjustable pressure-control valve of air pressure.
Background technology
Pressure-control valve belongs to the one of valve, has at daily life and industrial circle and has been widely used.From media such as continuous medium, sky gas and water, steam, various Korrosionsmedium, mud, oil products, but big class is seen and can be attributed to gas-pressure controlling valve and the fluid pressure control big class of valve two.For gas-pressure controlling valve, widely used at present have gravity type to regulate valve, electric control valve and proportional pressure control valve.The advantage of electric control valve is highly sensitive, it is not necessary to external impetus, when due to electronic unit, circuit etc. complex, often break down, reliability decreases.Gravity type regulates valve and adopts own wt to realize the release of pressure, thus the control of pressure is fixing, it is difficult to according to reality, the change carrying out necessity in real time and adjustment.Relative to manual modulation valve, its advantage is able to be automatically adjusted；After proportional pressure control valve adopts piloted reducer, structure thickens, it is unfavorable for inspection and repair system, proportional pressure control valve is suitable only in closed-loop water system (such as hot-water heating system, air conditioning water system) simultaneously, can more easily realize the assignment of traffic of system and the dynamic equilibrium of system.
Summary of the invention
For overcoming the deficiency of existing all kinds of pressure valve, this utility model provides one to be used in conjunction with each other by bypass pressure table and control valve, between the adjustable pressure-control valve of air pressure automatically lost heart with manual voltage regulation.
The technical scheme is that the adjustable pressure-control valve of air pressure is regulated and the body that loses heart, trachea and what air gauge was constituted by pressure for realizing the purpose of this utility model, trachea is connected with air gauge one end in the way of three UNICOMs, the other end regulates with pressure and is connected with the body that loses heart, and the 3rd end is connected with the pressurized tank of user by flange.
Described pressure regulates and loses heart body, structure for hollow cylinder, by housing, bleeder port, regulate head with the propulsion arm of spring and pressure and constitute, be positioned at pressure with the propulsion arm of spring and regulate and on the axis of the body that loses heart, and regulate chimeric with the lower surface of the body that loses heart with pressure；Bleeder port is positioned at pressure and regulates and on the downside sidewall of the body that loses heart；Pressure regulates head and is positioned at pressure adjustment and the upper surface of the body that loses heart, and is coaxially disposed with the propulsion arm with spring.
The described propulsion arm with spring, for " ⊥ " structure, axis is cased with spring, and the upper end of " ⊥ " is embedded in pressure and regulates in head concave groove, and the upper end of " ⊥ " can slide up and down in Baltimore groove.
The described propulsion arm with spring, for " ⊥ " structure, the lower surface of " ⊥ " is provided with annular groove.
Described pressure regulates and the lower surface of the body that loses heart, for circular configuration, in be provided with passage in the heart, its face is additionally provided with ring-type convex shape simultaneously, this ring-type convex shape just with the annular groove tabling set by the lower surface with the propulsion arm of spring, thus ensureing to do at ring-type convex shape with the propulsion arm of spring relatively to move up and down.When tracheal strips gas pressure is less than the spring force of propulsion arm, propulsion arm bottom surface blocks passage；When tracheal strips gas pressure is more than the spring force of propulsion arm, propulsion arm bottom surface is by gas pressure jack-up, and gas is discharged.The required gas pressure size controlled of pressure-control valve, depends on the spring degree after adjusting, and the foundation adjusting spring is that trachea bypasses the air gauge connect, thus realizing the operation principle of described " air pressure is adjustable ".
Described pressure regulates head, and for T-shaped structure, T-shaped lower surface is provided with sliding eye and the spring detent of annular.
Described pressure regulates head, regulates with pressure and is connected threadably between the upper surface of the body that loses heart, and rotation pressure regulates head, the elasticity of adjustable spring.
The beneficial effects of the utility model are:
1, owing to this utility model have employed spring assembly, entirely different with traditional gravity mode, thus he both can vertically-mounted use on equipment, it is also possible to level is installed and used, the strong adaptability of use, not by the restriction in space.
2, owing to this utility model have employed spring assembly, thus same a set of control valve, the pressure limit (safe pressure voltage) certain) in, can arbitrarily set required force value as required.
Accompanying drawing explanation
Fig. 1 is a kind of adjustable pressure-control valve longitudinal profile schematic diagram of air pressure described in the utility model.
Detailed description of the invention
In order to this utility model is had a better understanding, this utility model is described further by the accompanying drawing that combines
In Fig. 1,1 is that pressure regulates head；2 is the adjustable Stress control valve chamber of air pressure, and 3 is spring；4 is the propulsion arm with spring；5 is bleeder port；6 is trachea；7 is O-ring seal；8 is flange；9 is Pressure gauge.
Utilize said structure, by trachea (6), O-ring seal (7) and flange (8), adjustable for air pressure pressure-control valve is installed on a kind of loquat wine brewing jar.When brewageing beginning, loquat juice, the yeast of activation and appropriate water are entered brewing jar by charging aperture, requirement according to fermentation technology in sweat, the barometric indicator of Real Time Observation, adjust pressure and regulate head (1), make bleeder port stable a certain by spending time start discontinuity and lose heart and reduce pressure.
