[0013] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] In this application, unless otherwise clearly specified and limited, the terms "connection" and "fixation" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0015] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "horizontal", "top", "bottom", "upper", "lower", "inner" and "outer" etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0016] In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. In the description of the present utility model, "a plurality of" means two or more unless otherwise clearly and specifically defined.

[0017] As Figure 1 - Figure 2 shown, the present utility model provides a water pressure test pump water device for a small liquid discharge tank, which is used in cooperation with the small liquid discharge tank. The small liquid discharge tank has a water inlet and an external connection pipe. This device includes a tee 10, a plug 20, an adapter 30 and a pump water connection 40.

[0018] The tee 10 has an exhaust hole 11 and two meter connection holes 12. The exhaust hole 11 and the two meter connection holes 12 are both in communication with the inside of the tee 10. The exhaust hole 11 is located on the side wall of the tee 10, and the two meter connection holes 12 are respectively located on both sides of the top of the tee 10. The plug 20 is arranged in the exhaust hole 11 and is used to block the exhaust hole 11. The first end of the adapter 30 is in communication with the inside of the tee 10. The first end of the pump water connection 40 is connected to the external connection pipe on the small liquid discharge tank, and the second end of the pump water connection 40 is connected to the second end of the adapter 30.

[0019] In the initial state, the plug 20 is not inserted into the exhaust hole 11.

[0020] The specific use process of this device is as follows: The staff pumps water into the small liquid discharge tank from the water inlet of the small liquid discharge tank through a water pump. The water flow sequentially passes through the water pumping joint 40 and the transition joint 30 and enters the tee 10. When water overflows from the exhaust hole 11 of the tee 10, it indicates that the air in the small liquid discharge tank has been exhausted. Then, the exhaust hole 11 is blocked with the plug 20, and pressure gauges are installed at the two meter connection holes 12 for a water pressure test.

[0021] Through the combined use of the tee 10, the plug 20, the transition joint 30, and the water pumping joint 40, this device solves the problem that it is difficult to connect a pressure gauge to the external connecting pipe on the small liquid discharge tank. The structure of this device is simple, the operation is convenient, the manufacturing cost is low, and it is convenient to conduct a water pressure test on the small liquid discharge tank.

[0022] In one embodiment, the water pumping joint 40 is welded to the small liquid discharge tank to improve the stability of the entire device.

[0023] In one embodiment, the second end of the water pumping joint 40 is threadedly connected to the second end of the transition joint 30. This is to facilitate the disassembly of the transition joint 30 and the tee 10 after the water pressure test is completed.

[0024] In one embodiment, it further includes a gasket, and the gasket is arranged between the plug 20 and the exhaust hole 11 to improve the sealing performance between the plug 20 and the exhaust hole 11 and enhance the plugging effect.

[0025] The above shows and describes the basic principles, main features, and advantages of the present invention.
