Abstract

A high-pressure exhaust valve belonging to the field of fire fighting has rated working pressure of 16Mpa, can discharge air in pipelines in time, prevent air blocking and increase fire fighting response time, and resolves problems of low rated pressure, low exhaust capacity, poor reset and the like of a general exhaust valve. The high-pressure exhaust valve consists of a filter screen, a body, an air outlet joint, a spool, a drain core, a spring and the like, wherein the spool is made of materials with density lower than that of water and keeps opened normally by aid of spring action and dead weight, the body is provided with a spool cavity, a drain hole and peripheral air-guide passages, most of high-pressure air flow is exhausted from the peripheral air-guide passages along the upper portion of the spool so as to solve the difficult problem of closing caused by high-pressure airflow impaction, the spool is driven to flow to the outlet so as to be closed hermetically when water is ascended, buoyancy is reduced when air is accumulated in the pipeline again, and the spool moves downwards by actions of the spring and the dead weight of the spool so as to be reset and opened, thereby recovering exhaust functions. The high-pressure exhaust valve has wide application prospect on library archives water spraying fire fighting systems and the like.

Description

High pressure air exhaust valve

Technical field

The utility model relates to a kind of fire protection sector that is used for, and gas in the pipeline is got rid of automatically, and rated working pressure reaches the outlet valve of 16MPa, belong to fire-fighting domain.

Background technique

Present outlet valve, rated working pressure is 1.2MPa mostly, air displacement is less.

Present outlet valve valve body material cast iron, cast steel, copper.

Summary of the invention

In order to fill up problems such as not having high pressure air exhaust valve in the high-pressure fine water mist fire-extinguishing system.The utility model provides a kind of high pressure air exhaust valve, can be in high-speed large-flow exhaust under the 16MPa, and at 17.6MPa hydraulic pressure lower seal, the unlatching exhaust can automatically reset when gas occurring again behind the exhaust water-filling.

The utility model is achieved in that high pressure air exhaust valve is made up of body, spool, air outlet adapter, spring, O RunddichtringO, draining core, filter screen, lock plunger etc.The hemisphere filter screen is adopted in the high pressure air exhaust valve import, and outer perimeter strengthens with the stainless steel sheet bound edge, and filter screen is pressed in the inlet passage with lock plunger, guarantees the reliability of spool long-term work.Body is made up of eight uniform outer side through hole and a middle part port, and the middle part port is inlaid with the draining core, and the draining core is a tangential entry, has avoided the blow floating effect of high pressure draught to spool, but surplus water emptying, and lasting current come in to float spool.Spool employing density is that the polypropylene material of 0.8 times in water is made, suction side is a cone, the cone top-slitting, outlet side is a cylinder, is milled with flat filament, can lead and have the passage of big exhaust, the middle part is provided with the sealing of O type circle, and being with the unlatching spring that resets, O type circle Seal Design has accurate compression spacing, the unlatching reseting performance when reaching the 17.6MPa sealing with the dehydration exhaust.

The beneficial effects of the utility model are: realized the 17.6MPa high pressure sealing performance; The spool jack-up mistake that blows floating of anti-high pressure draught is closed performance; When the exhaust water-filling is closed back import dehydration exhaust, reset and open the auto restore facility of exhaust; When preact water mist system and the startup of dry type water mist system, acceleration system exhaust water outlet in the raising system fire extinguishing reaction time, is filled up domestic and international blank.In thousands of meters transmission pipeline networks of middle pressure water mist system, can get rid of the air that the pipeline top is gathered at any time, effectively removed stifled, the vent plug problem of gas, reduce flow resistance, guarantee Security, the reliability of system.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a section of structure of the present utility model.

Fig. 2 is an outline drawing of the present utility model.

Fig. 3 is the vital part in the utility model: body figure.

Fig. 4 is the vital part in the utility model: spool figure.

Fig. 5 is the vital part in the utility model: draining core figure.

Screen pack: adopt the hemisphere screen pack, outer perimeter strengthens with the stainless steel sheet| bound edge, and screen pack is pressed in the intake channel with lock plunger, guarantees the reliability of spool long-term work.

Body: be made up of a plurality of uniform outer side through hole and a middle part port, the middle part port is inlaid with the draining core, and the draining core is tangential entry, has avoided the blow floating effect of high pressure draught to spool, and surplus water can be emptying; Lasting current come in to float spool.

Spool: employing density is that the polypropylene material of 0.8 times in water is made. Inlet side is cone, the cone top-slitting; Outlet side is cylinder, is milled with flat filament, can lead and have the passage of big exhaust. The middle part is provided with the sealing of O type circle, and cover has the unlatching of resetting spring; It is spacing that the sealing of O type circle has compression, the unlatching reseting performance when reaching the 17.6MPa sealing with the dehydration exhaust.

The technical scheme in the invention for solving the technical problem is:

Press core component-spool, the body of this high pressure air exhaust valve of fluid mechanics three dimensional design, and exhaust repeatedly under Minimum operating pressure, rated working pressure, the Maximum operating pressure, on the unlatching that resets of water-stop, draining, anti-high pressure draught impacts, tests such as high pressure resistant sealing.Body adopts peripheral ventilating mode, has avoided having dashed the problem of closing at the quilt of high pressure draught lower valve core.The spool influent side is a cone, and outlet side is the flat filament axle, can guide-localization, can keep bigger air-flow conducting amount again.Water intake is established hemisphere and is strengthened filter screen, has improved spool reliability of operation up and down.

Embodiment

High pressure air exhaust valve is made up of body, air outlet adapter, spool, draining core, filter screen, lock plunger, spring, O RunddichtringO etc.Filter screen is loaded on high pressure air exhaust valve water intake inboard, and is fastening by lock plunger; Body and air outlet adapter are tightened by screw thread, and the draining core is embedded in the body influent side; The spool kink is in body, and top remains in normally open by spring.Air-flow in the pipe network enters body, the overwhelming majority flow to the air outlet adapter discharge through the passage of body periphery, sub-fraction flows to air outlet adapter through the tangential small-hole of draining core by the outside of spool, impacts the performance that mistake is closed because of youngster reaches bigger air displacement and anti-high pressure draught; Gas in pipe network row light, waterborne when coming, because of the proportion of spool is 0.8 times of water, its buoyancy that volume produced that is immersed in water is greater than deadweight rising top lifting sealing with length of spring compressed power.When the elutriation in the pipe network goes out bubble when the pipeline highest point gathers, the suffered buoyancy of outlet valve spool that is contained in the top disappears, under the force action of its spring thrust with deadweight, and spool moves down the unlatching exhaust.Reach real-time exhaust, stifled, the vent plug phenomenon of gas when having avoided the long distance of water mist system to carry.
