And its method.
Background technology
In API6A oil recoveries/gas wellhead equipment field, valve is indispensable part.It is well known that valve rises
To the effect for turning on or blocking fluid media (medium) and pass through, because the reliability of valve is directly connected to whole oil recovery/gas production wellhead dress
Put whether can normal operation, therefore need before dispatching from the factory to carry out hydrostatic pressing intensity detection, hydrostatic means of press seals to each valve
Performance test or airtight testing sealing, to judge whether valve is qualified.
Currently, when carrying out hydrostatic test, the equipment of needs is set by hydraulic test pump (low-lift pump, high-pressure pump), water tank, record
Standby, pressure gauge, high pressure line, blind flange, pressure testing room, screw bolt and nut etc. form.When carrying out airtight testing sealing, it is necessary to set
For by air compressor machine, cooling driers and filter, nitrogen cylinder, two-stage gas booster pump, pond, recording equipment, pressure gauge, high-voltage tube
Line, blind flange, melt pit, screw bolt and nut etc. form.Because the Meteorological of test room and melt pit is especially high, in general factory is difficult
To undertake.Other existing way there is problems:
1st, from the detection time of valve, in API6A specification, the detection to valve has special regulation,
The regulation be by user to condition determine manufacture requirements, that is to say, that select API6A in PSL1, PSL2, PSL3, PSL3G,
PSL4 is detected, and different manufactures requirement is different in detection time.So that PSL3 manufactures require as an example, a valve
Detection time take around 120 minutes, calculated by 8 hours within one day, can only also complete the detection of 4 valves, it is such
Speed obviously can not meet user's request.
2nd, from the detection method of valve, the general method that a deck valve door is detected using a set of equipment, exactly utilize
Hydraulic test pump is connected to valve one end by high pressure line, and to valve cavity injected media, detection operation is carried out using control device.
The above method is relatively backward for the enterprise for producing valve in enormous quantities, and the detection efficiency of daily separate unit detection device extremely has
Limit, efficiency are very low.
3rd, from the detection efficiency of valve, because valve is to produce in enormous quantities, it is very big to detect the workload of valve,
So the method for detection is particularly important.The detection of valve is the process repeated, it is meant that on each deck valve door will repeat
Operation is stated, if the method for detection does not change, its detection efficiency does not increase.
The content of the invention
In order to overcome above mentioned problem, an object of the present invention is to provide pressure testing dress that is a kind of while detecting multiple valves
Put, solve the problems, such as that existing pressure testing device detection efficiency is not high.
It is a further object to provide a kind of while detect the pressure-measuring method of multiple valves, solves existing method inspection
Survey the problem of cost is high, and intensity is big, and detection efficiency is low.
The technical solution adopted for the present invention to solve the technical problems is:Pressure testing dress that is a kind of while detecting multiple valves
Put, for carrying out hydrostatic pressing intensity detection and hydrostatic pressing experiments of sealing performance, including control cabinet, partial pressure test to valve to be detected
System and pressure testing table.Wherein, control cabinet is used to provide stable pressure of supply water to partial pressure test system, and it includes what is adjoined one another
Water tank and hydraulic test pump, the tape deck for recording all valve datas to be detected is also associated with hydraulic test pump.Partial pressure is tested
System is by a pressure distributor, and a plurality of pressure testing separated time composition being connected with pressure distributor, the pressure testing separated time have
Stop valve, pressure gauge and the reversal valve being sequentially connected with by the first pipeline, one end of first pipeline are connected with pressure distributor,
The other end connects with valve to be detected, and the second pipeline is additionally provided between pressure distributor and hydraulic test pump.Pressure testing table has two sets
Valve clamping bench group, every suit valve clamping bench group are respectively arranged with the valve clamping bench corresponding with valve quantity to be detected.
Preferably, pressure testing separated time is provided with five.The present invention can detect five valves in the unit interval, substantially increase work effect
Rate, user's request can be met.
Further, pressure testing separated time is also included for when hydrostatic pressing intensity detection is tested that the valve other end to be detected is close
The blind flange of envelope, the blind flange are unwanted in hydrostatic pressing experiments of sealing performance.
Further, the screw bolt and nut for installing valve to be detected is additionally provided with valve clamping bench.
As another theme of the present invention, pressure-measuring method that is a kind of while detecting multiple valves, filled using above-mentioned pressure testing
Put, comprise the following steps:S1. by valve to be detected be arranged on a set of valve clamping bench group on, and by one end of the first pipeline with
Valve valve port docks;S2. stop valve is opened, valve to be detected is opened or closed by testing requirements, pressure testing is started by control cabinet
Medium is pumped into pressure distributor by pump, is inputted medium to the inner chamber of multiple valves to be detected simultaneously by pressure distributor;
S3. if any valve to be detected finds seepage during pressure is entered, then the stop valve of the valve nose is directly closed, it is other to treat
Detection valve can continue into be depressed into complete detection;S4. when pressure reaches the pressure value of setting, hydraulic test pump pump trip is to be checked
Side valve door carries out voltage stabilizing by API6A requirements, and valve to be detected is not allow for any seepage during voltage stabilizing;If filled in record
Display seepage is put, then closes the stop valve of each pressure testing separated time respectively, whether observation corresponding pressure table has decompression, if any drop
Pressure, illustrates that the valve to be detected of the pressure testing separated time is unqualified;S5. after the completion of detecting, by reversal valve by pressure transmission to another
Set valve clamping bench group separately detects, and can dismantle the valve that above a set of detection is completed simultaneously in separately detection process.
Further, when carrying out the experiment of hydrostatic pressing intensity detection, in addition to blind flange is arranged on valve to be detected
The other end outlet the step of.
Beneficial effects of the present invention:
The present invention can be independently controlled to each valve to be detected, once seepage is found, as long as closing the leak valve
The stop valve held in front of the door, the continuation pressure testing of other valves would not be influenceed, be laid a good foundation to save disassembly and assembly time.It is of the invention big
The big waste for reducing water resource during pressure testing, streamline operation, has and improves production efficiency, reduce the excellent of production cost
Point.The present invention detects multiple valves in the unit interval, substantially increases operating efficiency, so that PSL3 manufactures require as an example, per complete
Into 5 valves detection with about when 120 minutes, in terms of 8 hours, the detection of 20 valves can be completed within one day, and then significantly
Reduce the testing cost of valve and the labor intensity of worker.In addition, can be in detection valve using two sets of valve clamping bench groups
The valve of another set of valve clamping bench group is removed and installed simultaneously, ensure that the continuity of work.
Below with reference to drawings and examples, the present invention is described in detail.
