Problems solved by technology

At present, rubber seal manufacturers at home and abroad seldom test according to this standard. The reason is that the cost is expensive, and the use of carbon dioxide and methane gas in the test is dangerous. However, high-end petroleum equipment customers require this performance to be tested. but getting higher

Embodiment Construction

[0011] Further detailed description will be given below in conjunction with the embodiments of the present invention and the accompanying drawings.

[0012] The rapid pressure release detection device for rubber seals as shown in the accompanying drawings includes a tooling 10, a test container and a valve group 30, wherein the tooling 10 is composed of a first bolt 11 connecting a lower cover 13 and an upper cover 12, and the lower cover 13 and the upper cover 12 is provided with central holes 131 and 121. The rubber seal 60 to be tested is placed on the lower cover 13, and the gasket 14 is placed on the screw hole of the lower cover 13 at the same time, then the upper cover 12 is placed on the rubber seal 60 and the gasket 14, and the first bolt 11 is screwed. Insert the lower cover 13 screw holes until the upper cover 12 is pressed tightly, and the rubber seal 60 is compressed at the same time. The gasket 14 is located between the lower cover 13 and the upper cover 12, the...

Abstract

The invention discloses a rubber seal rapid decompression detection device which comprises a tool, a testing container, a valve set and pipelines. The tool is formed by connecting an upper cover and a lower cover through a first bolt, and the testing container is formed by connecting an end cover and a tank body through a second bolt. The end cover is provided with an air inlet duct and an air outlet duct, the tank body and the end cover are provided with ring grooves which are connected in an opposite mode, and a sealing cushion ring is arranged inside each ring groove. The air inlet duct of the end cover is communicated with a supercharging stop valve of the valve set through the supercharging pipeline, and the air outlet duct of the end cover is communicated with a decompression stop valve of the valve set. The compression rate of a rubber seal can be limited, the rubber seal is in the environment which is sealed and capable of supercharging and decompressing rapidly to accomplish the rapid decompression detection of the rubber seal, operation is convenient and easy, and cost is low. The decompression speed in the detection process can be controlled, released carbon dioxide and methane can be limited in a gas protecting cover, a ventilation system exhausts the harmful gas safely and rapidly, and the effect of protecting the personal security of operation staff is achieved.

Description

technical field [0001] The invention relates to a rapid pressure release detection device for a rubber seal, which is used for detecting the performance of a rubber seal on an oil wellhead when the gas is rapidly released. Background technique [0002] Rubber seals are cheap, reliable, and simple, and are used in most oil wellhead and Christmas tree equipment. In oil wells, rubber seals with general performance can meet various working conditions; but in gas wells, rubber seals with general performance will expand and twist when the gas well is quickly released, and cracks will occur in the cross section of the seal. In severe cases, the entire The section is full of cracks and causes the rubber seal to fail completely, so there are special requirements for the performance of the rubber seal. Some countries have included the performance of rubber seals during rapid pressure relief as an important content in the testing standards. At present, rubber seal manufacturers at ho...
