Semi-automatic pressure testing machine for indoor bolts and its pressure testing method

Abstract

The invention relates to a semi-automatic press testing device used for indoor fire hydrants and a press testing method using the same. The press testing device comprises a rack, a fixing mechanism and a press testing mechanism, wherein the fixing mechanism and the press testing mechanism are assembled on the rack; the fixing mechanism comprises a base, an upper pressure head, a side plate and a first power device; the press testing mechanism comprises a press testing waterway system, a press testing head and a second power device; a water outlet of an indoor fire hydrant is covered by the upper pressure head; a water inlet end of the indoor fire hydrant is pressed between the side plate and the press testing head; a water inlet of the indoor fire hydrant is covered by the press testing head; the press testing waterway system is communicated with the water inlet of the indoor fire hydrant. The press testing method is characterized by putting and fixing the indoor fire hydrant according to a specific mode and carrying out primary press testing and secondary press testing on the indoor fire hydrant by using a press testing waterway system on the premise of not removing the indoor fire hydrant. The press testing device has a simple and easily used structure, long service life and little maintenance work, is lower in production cost, occupies small space and can achieve the effects of effectively reducing the workloads of workers and effectively improving the press testing efficiency.

Description

technical field [0001] The invention relates to a pressure testing device for a fire hydrant, in particular to a semi-automatic pressure testing machine for an indoor hydrant and a pressure testing method thereof. Background technique [0002] Indoor hydrant is the abbreviation of indoor fire hydrant. Indoor fire hydrant is the indoor pipe network that supplies water to the fire site. It has a valve interface and is an indoor fixed fire-fighting facility for factories, warehouses, high-rise buildings, public buildings and ships. It is usually installed in a fire hydrant box. It is used in conjunction with equipment such as fire hoses and water guns. After the finished indoor plug is obtained, it is necessary to test the structural strength of the indoor plug itself and the sealing effect of the valve disc. At present, a pressure testing machine is often used to test it. [0003] At present, the commonly used pressure testing machines test the indoor plug with the following ...
