Description
技术领域technical field
本发明属于安全阀性能测试技术领域，具体涉及一种安全阀压力整定和密封检测装置及方法。The invention belongs to the technical field of safety valve performance testing, and in particular relates to a safety valve pressure setting and sealing detection device and method.
背景技术Background technique
目前市场上安全阀常用的压力和密封试验方法主要是通过压力校验台进行，对于阀门的密封试验，其外泄漏的检测方法主要是通过捡漏液或者氦气进行检测，内泄漏主要通过入口进压，出口封堵后通过引漏管进入量杯检测(试验介质为液体)或数气泡法检测(试验介质为气体)，对于现有的安全阀压力整定和密封试验方法存在以下缺点：At present, the pressure and sealing test methods commonly used for safety valves in the market are mainly carried out through the pressure calibration bench. For the sealing test of the valve, the detection method of the external leakage is mainly through the detection of leakage liquid or helium gas, and the internal leakage is mainly through the inlet. After the outlet is blocked, enter the measuring cup through the leak pipe for detection (the test medium is liquid) or the bubble count method for detection (the test medium is gas). There are the following disadvantages for the existing safety valve pressure setting and sealing test methods:
1、现有试验台架一般都比较大，且固定在某一地方，阀门如需试验需吊运到指定位置，存在吊运磕碰和掉落风险，以及耗费来回吊运时间和人力物力；1. The existing test benches are generally relatively large and fixed in a certain place. If the valve needs to be tested, it needs to be hoisted to the designated location, which has the risk of bumping and falling during hoisting, and consumes time and manpower and material resources for hoisting back and forth;
2、对于出口无法进行引漏的阀门无法进行压力整定和密封试验；2. For valves that cannot be leaked at the outlet, pressure setting and sealing test cannot be performed;
3、对于非封闭式安全阀密封性能检测精准度较差；3. The accuracy of testing the sealing performance of non-closed safety valves is poor;
4、对于大口径阀门出口需加工专用引漏装置；4. For large-diameter valve outlets, special leakage devices need to be processed;
5、由于安全阀的压力整定均需人为对压力表陡降来判断整定压力值，存在人因不确定性和精准度低的问题。5. Since the pressure setting of the safety valve needs to be manually judged by the steep drop of the pressure gauge to determine the set pressure value, there are problems of human uncertainty and low accuracy.
针对以上问题，我们对安全阀的校验提出一种更为方便科学的方法来解决，这种试验方法精确度高，操作方便智能，无需人工目视判断安全阀整定压力，密封试验无需配置出口引漏装置或管线，也能携带至现场对阀门进行试验，只需与阀门入口连接就能实现压力整定和密封试验。In view of the above problems, we propose a more convenient and scientific method for the calibration of safety valves. This test method has high precision, convenient and intelligent operation, and does not require manual visual judgment of the set pressure of the safety valve. The sealing test does not need to configure the outlet. The leakage device or pipeline can also be carried to the site to test the valve, and it only needs to be connected with the valve inlet to realize pressure setting and sealing test.
