Description

An expansion buffer safety device

technical field

The utility model relates to an expansion buffer safety device, which is suitable for installation on equipment for non-explosive and non-toxic media or explosive and toxic media, and is mainly used in transportation pipelines in the fields of chemical industry, heat supply and toxic gas.

Background technique

The safety valve plays a role of safety protection in the system. When the system pressure exceeds the specified value, the safety valve opens to discharge a part of the gas or liquid in the system, so that the system pressure does not exceed the withstand pressure value of the pipeline, so as to ensure that the system does not cause accidents due to excessive pressure. However, because the traditional product has no buffer device, it may lead to the following two consequences:

(1) When high-temperature, high-pressure gas or liquid is discharged directly, casualties or other accidents may occur due to its sudden discharge.

(2) When the safety valve discharges high-pressure harmful gas or liquid through the conduit, it will have a large impact on the exporting equipment, which may cause leakage of toxic working fluid and pollute the environment.

Contents of the invention

The purpose of the utility model is to provide an expansion buffer safety device, adding a ring-shaped collection and buffer device, so that various high-pressure media can be exported and discharged stably and safely or introduced into the corresponding processing system. It also prevents accidental leakage due to large impacts and protects the environment. The collector has the characteristics of simple processing and convenient installation.

The technology of the utility model is realized in this way: an expansion buffer safety device, including a valve composed of an anti-rotation plate 5, a connecting shaft 6, a spring 8, an upper spring seat 4, a valve seat 14, a valve cover 3, and a valve disc 15 The body 2 is characterized in that: the valve body 2 is connected with the ring-shaped collection buffer 10 through screws 9 .

Beneficial effects of the utility model

(1) An annular collection and buffer device is added to enable various high-pressure media to be discharged smoothly and safely or introduced into the corresponding processing system.

(2) Prevent accidental leakage due to large impact, and protect the environment.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

The utility model includes a valve body 2 composed of an anti-rotation plate 5, a connecting shaft 6, a spring 8, an upper spring seat 4, a valve seat 14, a valve cover 3, and a valve flap 15. Buffer 10 is connected.

In order to discharge the liquid in the annular collection buffer 10 , a liquid outlet hole 16 is provided below the annular collection buffer 10 .

The ring collecting buffer 10 is connected with the pipeline through flanges 11 arranged at both ends thereof.

working principle

When the system pressure exceeds the specified value, the acting spring 8 of the high-pressure fluid is compressed, the valve disc 15 is pushed open by the high-pressure fluid in the pipeline, and the fluid flows into the ring-shaped collection buffer 10 through the valve hole 13, and then the fluid on the ring-shaped collection buffer 10 The outlet hole 16 leads to discharge or leads to a corresponding treatment device for further treatment. When the system pressure drops to a specified value, the spring 8 stretches, driving the valve disc 15 to move down, closing the valve port, and the fluid in the system resumes normal operation.
