Description
Technical field
The utility model is related to a kind of safety valve water pressure test for strength device.
Background technology
Safety valve as the bearing devices such as boiler, pressure vessel, pressure pipeline overpressure protection apparatus install on line,
Pipeline can do water pressure test for strength before plant running, and in order to prevent safety valve jumping up, staff can apply to valve top part top plug
Plus an extra sealing force.When many sleeving valves do water pressure test for strength simultaneously on to a high pressure line or a steam pipe line
Wait this method and expose problems with：
1st, sealing force extra on high pressure line is unable to the hydraulic pressure of bucking-out system；
2nd, can not be simultaneously to many deck valves on a pipeline while plus/minus sealing force.
As shown in Figure 1：Conventional press is realized using the structure of protective cover 7 and top plug 8.Applying power is calculated before experiment
Then size tightens top plug 8 using torque spanner, and pressure testing is ensured by pushing up plug 8 to the one extra sealing force of application of flap 5
When valve not take-off.But this method can not be used in the screw strength that additional sealing force is more than plug screw.Therefore design a kind of
System suitable for high pressure line and many sleeving valve simultaneous tests is necessary.
The content of the invention
The purpose of this utility model is to provide a kind of safety valve water pressure test for strength device.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：
A kind of safety valve water pressure test for strength device, for be connected with valve fixation kit, be connected to described consolidate
Determine the driving part of the top pressure part and the described top pressure component actuation of driving on component, the top of the experimental rig described in many
Splenium part shares the driving part described in one, described top pressure part can downwardly against safety valve valve rod.
Preferably, described driving part includes the pipeline being connected with the top pressure part described in one end and described pipe
The transfer tube that the other end on road is connected.
It is further preferred that described top pressure part is hydraulic jack, the piston of described hydraulic jack can be to
Under push down the valve rod of safety valve.
It is further preferred that described transfer tube is oil transfer pump.
Preferably, described top splenium part is connected by screw on described fixation kit.
Preferably, described fixation kit includes fixed seat, many connecting screw rods being connected in described fixed seat, institute
The top pressure part stated is connected in described fixed seat, and described screw rod is mutually fixed with valve.
It is further preferred that described screw rod is connected to by nut in described fixed seat.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
1st, the water pressure test for strength of high pressure line can be useful in；
2nd, plus/minus sealing force while device can be realized.

Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
A kind of safety valve water pressure test for strength device as shown in Figure 2, for be connected with valve fixation kit, be connected
The driving part of top pressure part and driving top pressure component actuation on fixation kit, the top pressure part of many experimental rigs is total to
With a driving part, top pressure part can downwardly against safety valve valve rod.In the present embodiment：
Top pressure part uses hydraulic jack 10, the piston 100 of hydraulic jack 10 can downwardly against safety valve valve
Bar 6.
Driving part includes the pipeline being connected with one end top pressure part, the transfer tube being connected with the other end of pipeline.
Due to using hydraulic jack 10, pipeline is pipeline road 20, and transfer tube is oil transfer pump 21, and one oil transfer pump 21 of operation can be same
When to multiple hydraulic jacks 10 carry out operational control, as shown in Figure 3.
Fixation kit includes fixed seat 30, many connecting screw rods 31 being connected in fixed seat 30, wherein：Fixed seat 30 can
So that using butterfly seat, screw rod 31 is connected in fixed seat 30 by nut 32,33, and hydraulic jack 10 is connected to by screw 11
In fixed seat 30.
The pressure process of lower the present embodiment is illustrated in detail below：
As shown in Figure 3：Screw rod 31 is connected on valve, nut 32 is screwed in into screw rod 31, fixed seat 30 is passed through into screw
11 are fixed together with hydraulic jack 10 is then placed within nut 32 and then is fixed screwing in nut 33；By hydraulic jack
10 link together with oil transfer pump 21 with pipeline road 20 is crossed；
According to operation maintenance handbook data after valve installation, the output oil pressure of oil transfer pump 21 to operating pressure ejects oil pressure thousand
Sealing force is finally applied to flap 5 by the contact valve rod 6 of piston 100 on jin top 10；
If in process of the test pipeline boosting exceed test pressure field adjustable personnel according to operation maintenance handbook oil pressure with
Test pressure relation table, operation oil transfer pump 21 carries out the supplement of sealing force to flap 5.
