Embodiment Construction

[0024] A detection device for a low temperature cut-off valve, such as figure 2 shown, including:

[0025] It is used to connect the first side plate 2 of the sealed steel pipe end. The screw connection seat 1 (including O-shaped rubber ring and rubber backing plate) is connected to the first side plate 2 through threads, and one end of the screw connection seat 1 is connected to the detection end through threads. It is sealed with an O-shaped rubber ring, and the other end is connected with the stop valve 9 steel pipe, and sealed with a rubber backing plate;

[0026] The fixed bottom plate 3, which is used to fix two side plates 2 and 8 and has a slideway, can be installed on a fixed detection bracket or used for mobile detection;

[0027] Screw seat 4 (including O-shaped rubber ring, screw, pressure plate, etc.) used to detect and seal the threaded end of cryogenic globe valve 9, and the connection with the threaded end of the valve is sealed by O-shaped rubber ring;

Abstract

The invention discloses a detection device and a detection method of a low temperature cut-off valve. The detection device includes a fixed base plate, a first side plate, a second side plate and a guide rod mounted on the fixed base plate, a screw connection seat with a hollow channel mounted on the first side plate, and a screw connection seat mounted on the guide rod with a The screw seat of the hollow channel, and the adjustment mechanism installed on the second side plate for adjusting the detection space between the screw connection seat and the screw seat; one end of the screw connection seat is used to connect with the connecting hose as the detection source , and the other end is used for threaded connection with the pipe end of the shut-off valve to be tested; one end of the screw seat is the inlet end, used for threaded connection with the internal thread end of the shut-off valve to be tested, and the other end of the screw seat is connected with the One end of the adjustment mechanism is connected, and the outlet end of the screw seat is arranged on the side wall of the screw seat for installing a plug. The invention solves the difficult problem that the low-temperature cut-off valve is inconveniently sealed due to the inconvenient sealing of the external connection pipe and the connection test delivery pipeline during the detection test.

Description

technical field [0001] The invention relates to a detection device and a detection method of a low-temperature cut-off valve, which are mainly suitable for testing and testing of a low-temperature cut-off valve. Background technique [0002] In recent years, with the rapid development of the country, new energy natural gas has been widely used due to its environmental protection, cleanliness and economic benefits, and there are more and more supporting equipment for natural gas storage and transportation. Among them, low temperature valves are used in large quantities. Since one end of the low temperature globe valve has a welded pipe and the other end is threaded, the efficiency of conventional detection is not high, and it is cumbersome to replace the low temperature globe valve to be tested during the detection process. There is no good continuity and time-consuming strenuous. Contents of the invention [0003] The invention aims to provide a detection device and detec...
