Abstract
The utility model relates to an air tightness testing device for a rubber base inflating valve body, which is characterized by comprising an upper end cover (1) and a cylinder (4). An air inlet (5) is arranged at the bottom of the cylinder (4) and communicated with an inner cavity (6) of the cylinder (4), a rubber seal pad (3) is disposed in the inner cavity (6) of the cylinder (4), the upper end cover (1) is connected with the upper portion of the wall of the inner cavity of the cylinder (4) in a threaded manner, a screw cap (7) protruding upward is arranged at the top of the upper end cover (1), a stepped through hole with a large top and a small bottom is arranged on the upper end cover (1), an internal thread is arranged on the lower portion of the through hole, and the internal thread is matched with an external thread of a base of the valve body. The air tightness testing device is capable of testing aright tightness of the valve body of the rubber base inflating valve before being vulcanized, the valve body is observed for defects such as pores and the like so as to ensure product quality, and the whole air tightness testing device is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of rubber base valve mouth body tightness test device.
Background technology
Rubber base valve in the past all is to carry out the impermeability experiment later on again at valve cock mouth body sulfuration upper rubber base, be difficult to valve cock mouth body is carried out the impermeability experiment, if valve cock mouth body impermeability is bad, in the end just can be detected finished product the time, make intermediate controlled link disappearance, the final products qualification rate reduces, cause the raising of production cost, and after the sulfuration upper rubber base, can cover some defectives of valve cock mouth body, make that product quality is difficult to be guaranteed.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of rubber base valve mouth body tightness test device is provided, and it can detect the impermeability of rubber base valve mouth body before not vulcanizing, and guarantees product quality.
The purpose of this utility model is achieved in that a kind of rubber base valve mouth body tightness test device, it comprises upper end cover and cylinder body, described cylinder base is provided with air intake opening, the intracavity inter-connection of described air intake opening and cylinder body, be provided with rubber gasket in the inner chamber of described cylinder body, described upper end cover is connected with inner chamber of cylinder block wall top by screw thread, the described upper end cover top turncap that is provided with protruding upward, described upper end cover is provided with and up big and down small step-like through hole, described through hole bottom is provided with internal thread, and described internal thread matches with mouth body base external thread.
Principle of work: before valve cock uncured rubber pad, with valve inside by the standard torque valve cock core chamber of packing into, and then valve cock is screwed into upper end cover by mouth body whorl of base, and make its cut-off shoulder and rubber seal compress sealing, by being threaded upper end cover is screwed into cylinder body at last, valve base and rubber gasket compress sealing.After assembling finishes whole device is put into water vat, and keep whole device to be positioned under the liquid level.Open source of the gas this moment, and pressure gas is through the air intake opening access to plant and continue for some time, and whether observe valve cock mouth surface and mouth mouth has bubble to produce, as bubble occurs and constantly produce, and illustrates that then mouth body impermeability is not good.
Compared with prior art, the beneficial effects of the utility model are:
The utility model rubber base valve mouth body tightness test device can detect rubber base valve impermeability of mouth body before sulfuration not, and whether observation mouth body exists defectives such as pore, guarantee product quality, and whole apparatus structure is simple, easy to operate.
