Embodiment Construction

[0024] A detection device for low temperature stop valve, such as figure 2 Shown, including:

[0025] Used to connect the first side plate 2 of the sealed steel pipe end, the screw connection seat 1 (including O-shaped rubber ring, 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 O-shaped rubber ring, the other end is connected to the steel pipe of the shut-off valve 9 and sealed with a rubber backing plate;

[0026] A fixed bottom plate 3 with slide rails for fixing two side plates 2, 8 can be installed on a fixed detection bracket or used for mobile detection;

[0027] The screw seat 4 (including O-shaped rubber ring, screws, pressure plate, etc.) used to detect and fix the threaded end of the low-temperature shut-off valve 9 is sealed with O-shaped rubber ring for the connection with the valve threaded end;

[0028] Used to detect the sealin...

Abstract

The invention discloses a detection device and method for a low-temperature stop valve. The detection device comprises a fixed bottom plate, a first side plate, a second side plate, a guide rod, a screw connecting seat, a screw seat and an adjusting mechanism, wherein the first side plate, the second side plate and the guide rod are mounted on the fixed bottom plate; the screw connecting seat is mounted on the first side plate and has a hollow channel; the screw seat is mounted on the guide rod and has a hollow channel; the adjusting mechanism is mounted on the second side plate and used for adjusting a detection space between the screw connecting seat and the screw seat; one end of the screw connecting seat is connected with a connecting hose used as a detection source and the other end is in threaded connection with a hose connecting end of the too-be-detected stop valve; one end of the screw seat is an inlet end and is in threaded connection with an inner threaded end of the to-be-detected stop valve, the other end of the screw seat is connected with one end of the adjusting mechanism, and an outlet end of the screw seat is arranged on the side wall of the screw seat and used for mounting of a plug. The detection device and method solve the problem that an outer connecting hose and a connection test delivery pipeline are inconvenient to seal during detection tests on the low-temperature stop valve.

Description

Technical field [0001] The invention relates to a detection device and a detection method for a low-temperature cut-off valve, which is 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 more and more natural gas storage and transportation equipment. Among them, the amount of low-temperature valve is large. Because the low-temperature stop valve has a welded pipe at one end and a thread at the other end, the conventional detection efficiency is not high, and the replacement of the low-temperature stop valve to be tested during the detection process is cumbersome, without good continuity, and time-consuming Laborious. Summary of the invention [0003] The invention aims to provide a detection device and a detection method for a low-temperature cut-of...
