Abstract
A high pressure air safety valve is applied to pipeline systems in mechanical industry. The whole device of the safety valve comprises a regulating screw cap, a valve body, a spring, a spring seat, a lock nut, a valve clack, a regulating nut, a valve seat, a round pin and a sealing washer. The valve body is installed on the valve seat; the valve body and the valve seat are fixed tightly through the round pin; the sealing washer is installed on the valve clack; both the sealing washer and the valve clack are installed on the valve seat; the lock nut and the regulating nut are installed on the valve body; the spring seat and the spring are installed on the valve body; and the regulating screw cap is installed on the upper part of the valve body. The operating principle of the safety valve is that when medium pressure in a system rises abnormally and reaches up to the opening pressure, a valve gate is automatically opened; and the medium discharges pressure outwards through eight small holes all around. When the pressure decreases to the reseating pressure, the valve gate is automatically closed. The safety valve has the advantages of advanced design, reasonable structure, safety, energy conservation, prolonged service life and good sealing effect. The safety valve can ensure safe operation of pressure pipeline systems.
Description
Technical field:
The present invention relates on pressurized equipment such as boiler, pressurized container a kind of high-pressure air safety valve as overpressure protector.
Background technique:
At present; safety valve is a kind of being applied on the pressurized equipment such as boiler, pressurized container as overpressure protector; when container or pipeline internal medium surpass authorized pressure; act on active force on the flap greater than spring force or weight power after; flap rises automatically; valve opening reaches total travel, discharges unnecessary gas.Treat container or manifold pressure drop to be lower than normal operating pressure after, flap drops on the valve seat automatically, stops gaseous emission, container or pipeline recover proper functioning.
Safety valve is an automatic valve, by Regulation spring pressure, sets valve opening pressure, and when container inner pressure surpassed opening pressure of safety valve, safety valve was opened medium is discharged, and safety valve cuts out automatically after reaching Reseating pressure of a safety valve, the protection device security.When container pressure surpassed opening pressure of safety valve once more, safety valve still can be finished entire work process.
Sustainable development along with Chinese national economy, China's energy industry has been proposed very urgent requirement, and the angle of collateral security energy security is set out, for the industrial field safety valve, action in the state of accident is a big technical problem of being badly in need of solution in related domain promptly and accurately.The flap of common safety valve adopts goes up sealing configuration, makes that to compress a center of gravity higher, be difficult for sealing, and its Lift is non-adjustable, and behind the product export, Lift is fixed, and can not satisfy the requirement that the client adjusts discharge capacity.Will cause the generation of the significant wastage and the serious accident of the energy like this.Therefore develop a kind of high-pressure air safety valve is new problem anxious to be solved always.
Summary of the invention:
The purpose of this invention is to provide a kind of advanced design, rational in infrastructure, energy-saving safe, raising working life, good sealing effect, can guarantee the high-pressure air safety valve of pressure pipeline system safe operation.
The object of the present invention is achieved like this: high-pressure air safety valve, whole device is made up of adjusting nut, valve body, spring, spring seat, locking nut, flap, adjusting nut, valve seat, straight pin, sealing gasket, valve body is installed on the valve seat, and the two is tightened up with straight pin, sealing gasket is installed on the flap and is installed on the valve seat together, at valve body locking nut, adjusting nut are installed, mounting spring seat, spring in valve body, and will regulate the top that nut is installed in valve body; Its working principle is: when the unusual rising of pressure medium in the system reached cracking pressure, valve was opened automatically; Medium is by eight outside discharge pressures of aperture around the valve body.When pressure was reduced to Reseating pressure of a safety valve, valve was closed automatically.
Main points of the present invention are the structural type and the working principle of its product.Its working principle is: when the unusual rising of pressure medium in the system reached cracking pressure, valve was opened automatically.Medium is by eight outside discharge pressures of aperture around the valve body.When pressure was reduced to Reseating pressure of a safety valve, valve was closed automatically.Because of safety valve belongs to the self-acting valve class, it is the protective gear of system.When intrasystem pressure medium surpassed the safety value of regulation, the active force that utilizes medium itself was that closure member (flap) is opened discharge medium automatically; Because of the medium of this patent valve is " high-pressure air ", when the structural design of valve body, take into full account the Security of its system, valve body is designed structure for this reason, eight outside discharge pressures of aperture because valve body evenly distributes, to guarantee that medium can in time discharge, avoid the generation of serious accident, make it meet the industrial and mineral conditional request.The flap of common safety valve adopts the hard sealing material, do not rub relatively and have between the sealing surface of safety valve, through open up and down repeatedly and closing motion after, sealing occurs " scratch " easily and reaches " erosion " phenomenon, this destruction is more obvious in the high pressure steam medium, destroying infection to sealing is very big, is difficult for sealing.The sealing material of high-pressure air safety valve adopts flexible barrier material-high pressure rubber material, will avoid occurring " scratch " and reach " erosion " phenomenon, has not only guaranteed reliable sealing performance, has improved the working life of valve simultaneously.
High-pressure air safety valve compared with prior art has advanced design, rational in infrastructure, energy-saving safe, raising working life, good sealing effect, can guarantee advantages such as pressure pipeline system safe operation, will be widely used in the mechanical industry pipe-line system.

Concrete structure of the present invention is provided by following example and accompanying drawing thereof.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of flap part of the present invention.
Fig. 3 is the structural representation of valve body part of the present invention.
Embodiment:
With reference to accompanying drawing, high-pressure air safety valve, whole device is made up of adjusting nut 1, valve body 2, spring 3, spring seat 4, locking nut 5, flap 6, adjusting nut 7, valve seat 8, straight pin 9, sealing gasket 10, valve body 2 is installed on the valve seat 8, and the two is tightened up with straight pin 9, sealing gasket 10 is installed on the flap 6 and is installed in together on the valve seat 8, at valve body 2 locking nut 5, adjusting nut 7 are installed, mounting spring seat 4, spring 3 in valve body 2, and will regulate the top that nut 1 is installed in valve body 2; Its working principle is: when the unusual rising of pressure medium in the system reached cracking pressure, valve was opened automatically; Medium is by eight outside discharge pressures of aperture around the valve body.When pressure was reduced to Reseating pressure of a safety valve, valve was closed automatically.
