Embodiment 1

[0016] Such as Figure 1-4 As shown, the outlet hole of the gas test terminal is easy to install the seal, including the installation sleeve 1, the rubber ring 2 and the compression screw 3. The installation sleeve 1 is cylindrical, and a perforation 101 is arranged in the center, and the compression screw 3 is set There is a through hole 301, the outer diameter of the rubber ring 2 is consistent with the diameter of the perforation 101, and the inner diameter is consistent with the diameter of the through hole 301. An edge 102 is arranged on the outer peripheral wall of one end of the installation sleeve 1, and threaded holes 103 are evenly arranged on the edge 102 to compress The screw 3 is a threaded column whose outer diameter is consistent with the diameter of the perforation 101. It is threadedly connected in the perforation 101. The through hole 301 is coaxial with the perforation 101. One end of the compression screw 3 is a connecting end 302, and the other end is a rot...

Embodiment 2

[0019] Such as Figure 5 , the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that a threaded connection hole 305 is provided on the end surface of the handle 304 away from the compression screw 3, and the length of the handle 304 is generally designed not to be long, so as not to affect the appearance. And the gas test terminal is not easy to carry, and the threaded connection hole 305 is set, and an extended handshake can be connected, and the handshake can be removed after use, which is very convenient.

Abstract

The invention discloses an easy-to-install sealing piece for a fuel gas test terminal outgoing line hole. The easy-to-install sealing piece comprises an installing sleeve, a rubber ring and a compressing rotating part, the installing sleeve is cylindrical, a through hole is formed in the center of the installing sleeve, a through hole is formed in the compressing rotating part, one end of the compressing rotating part is a connecting end, the other end of the compressing rotating part is a rotating end, an outer screw thread is designed at the connecting end, axisymmetric handles are disposed at the rotating end, the handles are movable in the axial direction, and one end of the installing sleeve, which is far from the edges, is provided with a plurality of bayonets which are uniformly distributed along the circumference direction. The easy-to-install sealing piece for the fuel gas test terminal outgoing line hole has the advantages that the two symmetrical handles are disposed on the periphery walls of the compressing rotating part, the handles are movable in the axial direction, thereby, during usage, the two handles can be used for rotating the compressing rotating part, the handles can be moved and snapped into the bayonets on the installing sleeve, the compressing rotating part is prevented from reversely rotating, the installing is convenient, and the sealing performance is guaranteed.

Description

technical field [0001] The invention belongs to the explosion-proof field, and in particular relates to an easy-to-install sealing member for a gas test terminal outlet hole. Background technique [0002] The gas test terminal is used to send to the remote end and receive the remote signal. It is installed in the gas monitoring station, which is connected to various monitoring instruments in the monitoring station. Because it is close to the gas pipeline, it attaches great importance to explosion protection, especially the incoming and outgoing lines. If the gas leaks into the test terminal shell, it is prone to explosion, so the outlet hole needs to be sealed. At present, a seal is installed at the outlet hole. The seal includes a mounting sleeve, which surrounds the outlet hole, and the installation sleeve The rubber ring and the threaded post are set inside, and the cable passes through the outlet hole, the rubber ring and the threaded post, and the threaded post presses ...
