Abstract
The utility model relates to a connecting device for an air tightness test. The connecting device comprises an air inlet nozzle, a ball valve, interfaces, a connecting seat and a barometer, one end of the connecting seat is connected with the ball valve, the other end of the connecting seat is connected with the interfaces, and the middle part of the connecting seat is provided with the barometer. Since the barometer is connected on connecting equipment between compressed air and a device to be tested, the air tightness condition of the equipment to be tested can be intuitively observed.
Description
Technical field
The utility model relates to a kind of water-tight equipment tightness test coupling arrangement, especially relates to a kind of various water-tight equipment tightness test coupling arrangements that are applicable to.
Background technology
At present, for the equipment that will do air-tight test, being connected between equipment to be tested and pressurized air being mostly charging connector, ball valve and interface forms, interface is according to the needs of equipment to be tested, what have is helicitic texture, and what have is flange arrangement, when there is leakage in equipment to be tested, often can not accurately judge the size of equipment leakage amount to be tested, thereby can not accurately judge the actual impermeability situation of equipment to be tested.
The utility model content
The purpose of this utility model is to overcome above defect provides a kind of energy to observe the tightness test coupling arrangement of equipment impermeability situation to be tested.
The technical solution of the utility model is: it comprises admission piece, ball valve, interface, also comprises Connection Block and rain glass, and described Connection Block one end is connected with ball valve, and the other end of Connection Block is connected with interface, at the middle part of Connection Block, is provided with rain glass.
Being connected between described interface and equipment to be tested is threaded.
Described interface is connected with the flange that is connected between equipment to be tested.
The beneficial effects of the utility model are, on the coupling arrangement that rain glass is connected between pressurized air and equipment to be tested, thereby can observe intuitively the impermeability situation of equipment to be tested.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to accompanying drawing, a kind of tightness test coupling arrangement, it comprises admission piece 1, ball valve 2, interface I 5 or interface II 6, Connection Block 3 and rain glass 4, the left end of Connection Block 3 is connected with ball valve 2, the right-hand member of Connection Block 3 is connected with interface I 5 or interface II 6, be provided with rain glass 4 on Connection Block 3, being connected between interface I 5 or interface II 6 and equipment to be tested is threaded or flange is connected.
Due to rain glass 4 is connected between pressurized air and equipment to be tested, thereby can observe intuitively the impermeability situation of equipment to be tested.
It is more than preferred implementation column of the present utility model; for a person skilled in the art; the utility model can have various modifications and variations; all within the technical solution of the utility model; any modification of doing, be equal to replacement, improvement etc., all should be included in protection domain of the present utility model.
