Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of arrester close test device, including water tank 1, tank lid and vavuum pump 2；Water tank includes water
Case cavity 3, water inlet, delivery port and vacuum port 4, water tank cavity one end side wall upper part are provided with vacuum port 4, other end side wall upper part
Water inlet is provided with, bottom is provided with delivery port；Entery and delivery port is respectively arranged with inlet tube and outlet tube 5,6, and water inlet pipe fills with outside water storage
Put connection or be directly connected with originally faucet；Vacuum port is provided with pipe fitting 7；Pipe fitting 7 is connected with the one end of digital pressure gauge 8；Number
The word pressure gauge other end is connected with the air inlet of vavuum pump 2, and vacuum pump exhaust port is also associated with blast pipe（Not shown in figure）.
Tank lid of the present utility model is covered on water tank, forms sealing radiator cavity.The upper surface of water tank 1 is bonded with rubber
Circle circle 9, tank lid lower surface edge is provided with sealing ring 10；When tank lid covers, sealing ring 10 around rubber ring circle 9 and mutually
Contact, so, is arranged between tank lid and water tank by sealing ring and rubber ring double structure, strengthens sealing.
The utility model tank lid can have two kinds of designs in practice.As shown in Figure 2,3, tank lid includes scheme one
Framework 11, the upper and lower surface of framework inwardly set prominent upper and lower step 12,13；Glass 19 can be bonded on upper and lower step, by framework
Upper and lower surface sealing.As shown in Figure 3,4, including framework, framework upper table is inward-facing to set prominent step I 14, step II to scheme two
