Abstract

The utility model discloses a safety valve test and verification apparatus regulating pressure by use of a pressure regulator. The apparatus comprises a gas detection pipeline and a gas tank. The gas detection pipeline comprises an inlet valve, the pressure regulator, a pressure regulator outlet valve, a safety valve installation seat and an exhaust valve 8 which are connected in series through a pipeline; the outlet pipeline of the pressure regulator outlet valve is provided with a pressure meter; a detected safety valve is installed on the safety valve installation seat through a safety valve bottom valve; the gas tank is connected with a total pipeline at the position of the air inlet pipe of the safety valve installation seat through the pipeline; and the gas tank is provided with a sewage discharge valve. The apparatus provided by the utility model has the following advantages: the preparation is simple, the operation is convenient, and the implementation is easy. Besides, the apparatus can be specially used for safety valve debugging in an equipment performance test during an equipment manufacturing process, the safety and reliability are high, and the precision and sensitivity are quite high.

Description

A kind of safety valve test and calibration equipment that utilizes pressure regulator pressure regulation
(1) technical field
The utility model relates to test and the verification of gas burning pipeline safety valve, particularly a kind of safety valve test and calibration equipment that utilizes pressure regulator pressure regulation.
(2) background technology
In-line relief valve, according to national regulation, be installed on equipment and will carry out 100% verification, but in needing the manufacture process process of mounting safety valve equipment, need to carry out in advance equipment performance test, wherein also comprise safe Elution test, that its test unit must have is safe and reliable, high precision and sensitivity.Safety valve conventional test can only be carried out on production equipment, both dangerous also inaccurate.
(3) utility model content
The purpose of this utility model is for above-mentioned existing problems, a kind of safety valve test and calibration equipment that utilizes pressure regulator pressure regulation is provided, this device preparation is simple, easy to operate, easy to implement, in equipment Manufacture Process process, can be specifically designed to the safety valve debugging of carrying out in equipment performance test, safe and reliable and there is higher precision and sensitivity.
The technical solution of the utility model:
A kind of safety valve test and calibration equipment that utilizes pressure regulator pressure regulation, comprise gas detecting tube road and gas-holder, gas detecting tube road comprises imported valve, pressure regulator, pressure regulator outlet valve, installing seat for safety valves and vent valve 8 and is connected in series by pipeline, pressure regulator outlet valve outlet conduit is provided with tensimeter, and tested safety valve is arranged on installing seat for safety valves by safety valve bottom valve; Gas-holder is connected with the total pipeline at installing seat for safety valves draft tube place by pipeline, and gas-holder is provided with blowoff valve.
Workflow of the present utility model:
Tested safety valve is arranged on installing seat for safety valves, gases at high pressure enter through gas feed valve, and through pressure regulator pressure regulation, to predetermined pressure, pressure regulator endpiece arranges tensimeter, be convenient to monitor pressure regulator top hole pressure, through the gas of pressure regulation, enter gas-holder and use in order to test.While testing, adjust pressure regulator pressure is progressively raise, when pressure reaches safety valve and diffuses pressure, safety valve diffuses, and now for safety valve diffuses pressure, when the gas of storage tank stores can guarantee safety valve test, can obtain blow pressure accurately; When safety valve cuts out, the pressure of demonstration is exactly the blow pressure of safety valve, after revision test completes as requested, closes air intake opening valve, utilizes the exhaust-valve internal system pressure of having released, and pulls down safety valve, tests complete.
Advantage of the present utility model: this device preparation is simple, easy to operate, easy to implement can be specifically designed to the safety valve debugging of carrying out in equipment performance test in equipment Manufacture Process process, safe and reliable and have higher precision and a sensitivity.
