The prior art is compared, and the utility model at least has the following advantages：
1. it is simple in structure, it is quick and easy for installation, cost is saved, improves work efficiency.
Brief description of the drawings
Fig. 1 is the structure diagram of the structure for pressure test of the utility model in a state of use.
Fig. 2 is the part A partial enlarged view of structure for pressure test in a state of use shown in Fig. 1.
Embodiment
The structure and utility model content of the structure for pressure test of the utility model are described with reference to Fig. 1 and 2.
A kind of structure for pressure test for valve, including be sealingly mounted on valve 1 blocking 2, with blocking 2 needle-valves that are connected
3 and installed in valve 1 and the fixed clip 4 blocked.
The blocking is equipped with the through hole 5 connected with the inside of valve 1 and the sealing ring 6 coordinated with the sealing of valve 1.It is described
Through hole 5 is connected with needle-valve 3.
The needle-valve 3 includes valve body 7, the intake tunnel 8 for being arranged on 7 both ends of valve body and exhalant canal 9, installed in valve body 7
In adjusting spool 10 and the rotational handle 11 that is connected with adjusting spool 10.Connect between the intake tunnel 8 and exhalant canal 9
Vertical Channel 12 is connected with, three forms " Z " font.The intake tunnel 8 and exhalant canal 9 are arranged in parallel.The through hole 5 with
Intake tunnel 8 connects 9 with exhalant canal.The adjusting spool 10 includes tapered portion 13 and the adjusting rod being connected with tapered portion 13
Portion 14.The adjusting bar portion 14 is connected with rotational handle 11.Control rotational handle 11, you can to control to adjust the taper of spool 10
The aperture in portion 13, controls the size of flow, flexible and convenient operation.

Water channel 8 and exhalant canal 9.The blocking 2, connecting portion 15 and needle-valve 3 of the utility model are to be connected to one by the way of welding
Rise.
The valve of the structure for pressure test application of the utility model is four-way valve, and operating method is as follows：Clamped using pressure testing equipment
Plugging valve main road entrance end；Valve shunts one end is blocked using blocking 2 and clip 4, and symmetrical clip 4 passes through bolt and spiral shell
Female and next fixation realized to blocking 2；The other end is bypassed as shown in Figure 1, being blocked using same method, another is blocked not
Equipped with needle-valve；When boosting to the pressure needed for upper seal support experiment, needle-valve 3 is opened, valve is observed after emptying the chamber pressure of valve
Valve and upper seal support performance, complete flap and are tested with upper seal support.
In conclusion the above is only the preferred embodiments of the present utility model only, the utility model should not be limited with this
Scope.I.e. every simple equivalent changes and modifications made according to the utility model claims book and description, all should
Still belong in the range of the utility model patent covers.
