The beneficial effects of the utility model are: high water pressure test tube machine self sealss pressure charging system of the present utility model, and simple in structure, good stability use safety, and use cost is lower, is convenient to spread and uses, and practicality is stronger.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, exhaust end steel pipe radial seal head, 2, vent valve, 3, the exhaust head pedestal, 4, exhaust drags oil cylinder, and 5, discharge valve apparatus, 6, the exhaust end equalizing valve, 7, water inlet end radial seal head, 8, retaining valve, 9, the low pressure water intaking valve, 10, the water inlet end equalizing valve, 11, water intaking valve pedestal, 12, pressurized cylinder, 13, water inlet drags oil cylinder, 14, inlet valve mechanism.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises: the exhaust head part, formed by exhaust end steel pipe radial seal head, vent valve and exhaust head pedestal, and wherein said vent valve includes exhaust and drags oil cylinder, discharge valve apparatus, exhaust end equalizing valve; Low pressure water inlet head part is comprised of water inlet end radial seal head, retaining valve, low pressure water intaking valve, water intaking valve pedestal, and wherein said low pressure water intaking valve includes into water and drags oil cylinder, inlet valve mechanism, water inlet end equalizing valve; Pressurized cylinder is bolted on the water intaking valve pedestal of described low pressure water inlet head part.
During work, the pressure testing steel pipe that need detect is sent to the test station, the exhaust end steel pipe radial seal head (1) of exhaust end part is with the end sealing of pressure testing steel pipe, and the water inlet end radial seal head (7) of low pressure water inlet end part is with the other end sealing of pressure testing steel pipe.Open vent valve (2) and low pressure water intaking valve (9), after low-pressure water is full of the pressure testing steel pipe, close vent valve (2).Low pressure water intaking valve (9) is closed when the hydraulic pressure in the pressure testing steel pipe reaches predetermined 0.5MPa, and low-pressure water when pressure reaches 1MPa, stops water filling by retaining valve (8) water filling in the pressure testing steel pipe, and pressurized cylinder (12) is started working and compressed supercharging.When the hydraulic pressure in the pressure testing steel pipe reached 5MPa, press water entered respectively exhaust end equalizing valve (6) and water inlet end equalizing valve (10), and vent valve (2) and low pressure water intaking valve (9) enter the self sealss state; When the hydraulic pressure in the pressure testing steel pipe surpassed 5MPa, under the effect of exhaust end equalizing valve (6) and water inlet end equalizing valve (10), the water pressure in the pressure testing steel pipe and the pressure of pliability soft seal circle reached balance.Under the lasting supercharging of pressurized cylinder (12), pressure testing steel pipe internal pressure reaches to be set when requiring (the highest 130MPa of can be), enter packing state, the pressure of maintenance reaches when wanting seeking time whole system and carries out pressure release, and this moment opens vent valve (2) and low pressure water intaking valve (9) gets final product.
