Description

The gatevalve device of a gas punch by a heavy pressure punch}

The present invention relates to a gate valve device of a gas puncher for medium pressure punching, and more particularly, a gas for medium pressure punching, which facilitates drilling in a narrow working space by controlling an opening / closing valve using an electric means. A gate valve device of a perforator.

The general gate valve device includes a lower flange portion 3 screwed with the branch pipe 1, as shown in FIG. A plurality of bolt holes 2b fastened as bolts 2a are formed on the bottom face in contact with the flange portion 3, and the opening and closing hole 2c penetrates upward from the opened bottom surface, and the opening and closing hole 2c A body 2 formed with a guide space 2d on one side; An opening and closing plate 4a is installed to open and close the opening and closing hole 2c in the guide space 2d, and a screw shaft 4b is installed at one end of the opening and closing plate 4a so as to be protruded into the inside thereof. An opening / closing valve (4) provided with a steering wheel (4c) at the end of the screw shaft (4b) protruding to the side of the body (2); The upper flange 5a is coupled by a bolt 5b above the opening and closing hole 2c of the body 2, and the cylindrical portion 5d is screwed into the through hole 5c of the upper flange 5a. The upper body 5 is provided with a sealing cap 5e at the upper end of the cylindrical portion 5d, and an opening and closing side 5f for discharging gas therein to the side of the cylindrical portion 5d. ; The rotating shaft 6a is installed to penetrate the sealing cap 5e to the bottom of the opening / closing hole 2c of the body 2, and the opening 1a of the branch pipe 1 is provided at the end of the rotating shaft 6a. A coupling part 6b detachably attached to the inner cap 1b used to block the driving part, and a driving means 6 provided with a handle 6c at the upper end of the rotating shaft 6a; And the like.

However, in the conventional gate valve device configured as described above, since the operator manually rotates the steering wheel 4c of the on-off valve 4 directly, the opening and closing plate 4b perfectly closes the opening and closing hole 2c of the body 2. The work space is very unreasonable depending on the operator's sense of blocking the work, and in order to rotate the steering wheel 4c, the work space for adjusting the steering wheel 4c must be separately provided in the basement. In a narrow space that can not be prepared, there was a problem that the drilling of the gas pipe is impossible.

Accordingly, the present invention has been invented in view of the above problems, and facilitates the drilling operation in a narrow working space while controlling the open / close valve using the gate valve device using electrical means, while driving the open / close valve. It is an object of the present invention to provide a gate valve device for a gas perforation for medium pressure punching that enables a complete explosion-proof treatment by operating or stopping the motor by a position sensor inside the body.
