Abstract

The invention relates to a wall-penetrating device matched with a stainless steel corrugated hose for gas delivery. In the conventional wall-penetrating box, the threaded joint of a gas angle valve and a base elbow is easy to loosen, so that gas leaks and a leakage test is difficult to perform. The wall-penetrating device for the stainless steel corrugated hose for gas delivery comprises a cassette seat, and is characterized in that: the lateral surface of the cassette seat is provided with a gap, a 90-degree base elbow is fixed on the bottom surface of the cassette seat, the side end of the base elbow is provided with a thread interface, and a gas angle valve matched with the thread interface is arranged at the outer end of the base elbow. Through the wall-penetrating device, great convenience is brought to installation construction, torsion generated when the gas angle valve is installed on the base elbow is greatly reduced, and the strength requirement and the installation requirement on the cassette seat can be reduced; meanwhile, the potential safety hazard of gas leakage because the joint of the gas angle valve and the base elbow loosens is eliminated, and the leakage test is convenient to perform.

Description

technical field

[0001] The invention relates to a wall-out fixing device when a hose is concealed, in particular to a wall-out device used in conjunction with a stainless steel corrugated hose for gas transmission. Background technique

[0002] In recent years, my country has begun to promote the application of stainless steel corrugated hoses for gas transmission, and cities such as Beijing, Shanghai, Shenyang, and Shenzhen have been widely promoted and applied. At present, the open laying method is generally used in engineering design and on-site installation and construction, and the application of direct burying in the wall is rarely used. On the one hand, the construction of concealed burying is difficult, and on the other hand, the supporting products for the wall are not perfect, which will affect the stainless steel corrugated hose for gas transmission. Because the hidden burial will not affect the interior decoration effect, with the improvement of the living standa...

Embodiment Construction

[0020] As shown in the figure, there is a stainless steel corrugated hose outlet device for gas transmission. There is a gap 4 on one side of the cassette seat 1. A 90-degree base elbow 2 is fixed on the bottom surface of the cassette base 1. The side end of the base elbow 2 is a The threaded interface 3, the outer end of the base elbow 2 is equipped with a matching gas angle valve 8, the lower part of the gas angle valve 8 forms a piston rod 10, and the lower part of the piston rod is placed in the base elbow.

[0021] The outer end of the base elbow 2 is provided with an external thread 5, and two symmetrical bosses 6 are provided on the port. The piston rod 10 is provided with four opening grooves 9 evenly distributed on the circumference. According to different directions, two of the opening grooves are selected to be embedded in the two bosses 6, and the wedge type is realized through the cooperation of the bosses and the opening grooves. position. The bottom of the pist...
