The present invention provides a pressure release testing device which comprises a sign post which is installed at one end of an outer cover and is embedded into the outer cover. One end of the sign post is tightly connected to a membrane disc. The outer cover is internally equipped with a spring, and two ends of the spring are embedded into the inner surface of the outer cover. The spring is installed at one side of the membrane disc which is installed at one side of a sealing rubber ring. The sealing rubber ring is installed at one end of a switch which is arranged at the surface of the outer cover. The switch is installed at one side of a positioning handle which is installed at one end of a guide post and is embedded into the outer part of the guide post. The guide post is installed at one side of a side rubber ring which is installed at one side of a valve seat. The device has the advantages of compact structure and long life, the magnitude in pressure release can be controlled, the rapid positioning is achieved, the pressure detection is carried out, and the device has good social and economic effects and is suitable for promotion and use.
