Embodiment Construction
[0012] Below in conjunction with embodiment the present invention is described in further detail, but structure of the present invention is not limited to following embodiment:
[0013] 【Example】
[0014] Such as figure 1 , 2 As shown, the detachable outlet hole seal used for the gas test terminal includes an outlet hole 2 penetrating through the side wall of the box body 1, and a seal 3 arranged outside the outlet hole 2. The seal 3 is cylindrical. The center is provided with a perforation 301, and the perforation 301 is coaxial with the outlet hole 2, the diameter of the perforation 301 is greater than the diameter of the outlet hole 2, the rubber ring 4 and the compression screw 5 are arranged in the perforation 301, and the compression screw 5 is threaded in the perforation In 301, the compression screw 5 is provided with a coaxial hole 501 that matches the outlet hole 2, the outer diameter of the rubber ring 4 is consistent with the diameter of the perforation 301, the ...

The invention discloses a detachable wire outlet sealing element for a fuel gas test terminal. The detachable wire outlet sealing element for the fuel gas test terminal comprises a wire outlet (2) penetrating through the side wall of a box body (1), and a sealing element body (3) arranged on the outer side of the wire outlet (2), the sealing element body (3) is in a cylindrical shape, a penetrating hole (301) is formed in the center of the sealing element body (3), a rubber ring (4) and a compression rotating part (5) are arranged in the penetrating hole (301), the compression rotating part (5) is connected in the penetrating hole (301) through threads and is provided with a coaxial hole (501) matched with the wire outlet (2), the sealing element body (3) is installed on the box body (1) through an edge (302), and the penetrating hole (301) and the wire outlet (2) are coaxial. The detachable wire outlet sealing element for the fuel gas test terminal has the advantages that the sealing element body for sealing the wire outlet is detachably installed on the box body, when threads are damaged, only the sealing element body needs to be replaced, the box body does not need to be replaced, and cost is saved.
Description
technical field [0001] The invention belongs to the explosion-proof field, and in particular relates to a detachable outlet hole seal used for a gas test terminal. 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 hole needs to be sealed. At present, a stepped hole is set on the box body, the small hole faces inward, and the rubber ring is set in the big hole, and then use A threaded column presses the rubber ring, and the cable passes through the stepped hole, the rubber ring and the threaded post. The threaded post is threaded into the large hole, and the rubber ring ...
