The compression ratio of the rubber seal is limited, the rubber seal is disposed in an environment which is sealed and capable of pressurization and pressure relief so as to complete a rapid pressure release testing of the rubber seal, the operating is simple and the cost is relatively low. The pressure release speed can be controlled during testing process, released carbon dioxide and methane are confined in a gas protective cover, a ventilation system is adopted to discharge harmful gas safely and rapidly, and the operational personnel and the personal safety are protected.
Description
Technical field
The utility model is a kind of rubber seal quick pressure releasing pick-up unit, for detection of the performance of the rubber seal on the oil well head when the gas quick pressure releasing.
Background technology
Rubber seal has its cheapness, reliable, simple characteristics, is used in most of oil well heads and X-tree equipment.In oil well, the rubber seal of general performance can satisfy various operating modes, but in gas well, the rubber seal of general performance can produce expansion, reverse when the gas well quick pressure releasing, the seal xsect cracks, whole cross section discrepitate when serious and cause rubber seal thoroughly to lose efficacy is so have special requirement to the performance of rubber seal.In examination criteria is listed the performance of rubber seal when the quick pressure releasing as an important content by some countries.Present rubber seal both domestic and external manufacturer is also seldom according to this standard detection, reason is somewhat expensive, use carbon dioxide and methane gas that certain danger is arranged in the detection, but the cry that high-end oil equipment customer requirement is tested this performance is but more and more higher.
Summary of the invention
In order to adapt to the requirement in market, the utility model proposes a kind of rubber seal quick pressure releasing pick-up unit, improve detection speed, reduce testing cost.
The technical solution of the utility model is: a kind of rubber seal quick pressure releasing pick-up unit, comprise frock, test chamber, valve sets and pipeline, it is characterized in that, frock connects lower cover by the first bolt and loam cake forms, lower cover and on be covered with center pit; Test chamber connects end cap by the second bolt and tank body forms, and end cap is provided with air intake duct and the gas off-take that passes in the tank body, and the port of tank body and the end cap face corresponding with this port are provided with involutory annular groove, and annular groove is built-in with gasket ring; The air intake duct of end cap is connected the supercharging stop valve of valve sets by the supercharging pipeline, the gas off-take of end cap is connected the pressure release stop valve of valve sets by blowdown line.
Further, described valve sets by oil path block be communicated with drain cut valve, pressure source stop valve and described supercharging stop valve, described pressure release stop valve is formed, wherein drain cut valve is connected bleeder line, pressure source stop valve cut-in pressure source.
Further, the first bolt sleeve of described frock has pad, and pad is between lower cover and loam cake.
Above-mentioned test chamber can cover the gas shield cover in addition, and the gas shield cover is communicated with ventilation unit.
This pick-up unit can limit the compressibility of rubber seal, allow rubber seal be in a sealing, can supercharging and the environment of quick pressure releasing in finish rubber seal quick pressure releasing detect, easy and simple to handle, cost is lower.Can control pressure release speed in the testing process, the carbon dioxide that discharges and methane are limited in the gas shield cover, harmful gas safety, quick drain, play the effect of protection operating personnel's personal safety by ventilating system.
