Abstract

The utility model discloses an expansion buffering safe device, suitable for being mounted on equipment of the non-explosive and innoxious media or the explosive and noxious media, and is mainly applied to transfer pipelines in the mechanical field, the heat supply and noxious gas field and so on. The utility model comprises flanges 11, connecting screw holes 12, a fluid tapping 16, a protective cover 7, a valve clack sealing face 1, a stop plate 5, a connecting shaft 6, a spring 8, an upper spring seat 4, an annular collection buffer 10, a clack seat 14, mounting screws 9, a valve opening 13, a valve clack 15 and a valve body 2. The expansion buffering safe device of the utility model is provided with the annular collection buffer, various high pressure media are guided safely for discharge or guided in corresponding processing system, and accidental leakage caused by bigger impact is prevented, thereby protecting the environment. The device is characterized in simple processing, convenient installation and so on.

Description

A kind of expansion baffle safety device
Technical field
The utility model relates to a kind of expansion baffle safety device, is suitable for to be installed on the equipment of non-explosion hazard and nontoxic medium or explosion hazard and poisonous medium, is mainly used in the conveyance conduit in fields such as chemical industry, heat supply and toxic gas.
Background technique
Safety valve plays the safety protection effect in system.When system pressure surpassed specified value, safety valve was opened, and a part of gas in the system or liquid are discharged, and make system pressure be no more than the pipeline pressure resistance, thereby the assurance system did not have an accident because of overpressure.But, because traditional product does not have damping device, may cause following two kinds of consequences:
(1) when direct discharge high temperature, pressurized gas or liquid, because its unexpected discharging may cause casualties or take place other contingencies.
(2) when safety valve is discharged high pressure harmful gas or liquid by conduit, will produce greater impact, may cause poisonous refrigerant leakage, befouling environment derivation equipment.
Summary of the invention
The purpose of this utility model provides a kind of expansion baffle safety device, increases annular and collects damping device, makes the steadily safe derivation discharging of various high-pressure mediums or imports corresponding processing system.And prevent from the accidental release that brings owing to greater impact from environment have been played protective action.This trap has the characteristics such as simple, easy for installation of processing.
Technology of the present utility model is achieved in that a kind of expansion baffle safety device, comprise the valve body of being made up of torsional stop 5, coupling shaft 6, spring 8, upper spring seat 4, valve seat 14, valve gap 3, flap 15 2, it is characterized in that: described valve body 2 is collected buffer 10 by screw 9 and annular and is connected.
The beneficial effects of the utility model
(1) increases annular and collect damping device, make the steadily safe derivation discharging of various high-pressure mediums or import corresponding processing system.
(2) prevent the accidental release that brings owing to greater impact, environment has been played protective action.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model comprises the valve body of being made up of torsional stop 5, coupling shaft 6, spring 8, upper spring seat 4, valve seat 14, valve gap 3, flap 15 2, and described valve body 2 is collected buffer 10 by screw 9 and annular and is connected.
Collect liquid in the buffer 10 in order to discharge annular, below annular collection buffer 10, be provided with a liquid leadout hole 16.
Annular is collected buffer 10 and is connected with pipeline by the flange plate 11 that is arranged on its two ends.
Working principle
When system pressure surpasses specified value, the effect spring 8 of high-pressure liquid is compressed, flap 15 is backed down by pipeline mesohigh fluid, fluid flows into annular through valve opening 13 and collects buffer 10, is collected the fluid leadout hole 16 derivation dischargings on the buffer 10 or is imported corresponding processing means by annular again and further handle.When system pressure was reduced to specified value, spring 8 elongations drove flap 15 and move down, close port, and the fluid in the system recovers normal operation.
