A valve cover having a valve cover body, preferably of two sections. These sections are placed on either side of a valve. When joined, the sections enclose the valve, but form line apertures around the lines leading to and from the valve. Once the sections are in place, a cap is placed over the sections. The cap is sized to fit the sections tightly and will prevent the sections from separating. The cap may be provided with a tongue in groove mechanism to prevent accidental removal of the cap and to help secure the cap to the valve cover body. The cap and the valve cover body are also preferably provided with locking apertures. When these locking apertures are aligned, the cap may be secured to the valve cover body with a lock. With the valve cover locked in place around a valve, access to the valve is denied.

A semi-automatic mortising machine includes a support base, a support bar, a guide device, a working device, a distance adjusting device, and a dust collection box. Thus, the displacement direction can be controlled in a manual manner during the working process, and the cutting operation is performed in an automatic manner so as to cut the mortises and tenons in the workpiece.

The invention relates to a numerical-control multi-shaft seat mortising machine which comprises a base and a numerical control device, wherein a workbench is arranged at the top end of the base, a cantilever type spindle seat is arranged above the workbench, and a plurality of spindle milling cutters are arranged on the cantilever type spindle seat. The numerical-control multi-shaft seat mortising machine is characterized in that at least one group of workpiece clamp structure is arranged on the workbench, each group of clamp structure is formed by two multi-station clamps, and each multi-station clamp is formed by a clamping seat, a cylindrical clamping column, a pressing cylinder and a pressing plate; an L-shaped end surface is arranged at the rear side of the base, a horizontal linear guide rail and a vertical linear guide rail are fixed on the L-shaped end surface respectively along the length extension direction of the base; and a tool-measure device is fixed on the cantilever type spindle seat on one side of one of the spindle milling cutters. For the numerical-control multi-shaft seat mortising machine with the structure, material pressing is firmer, the overall structure is more compact and stable, and the service life and the precision of the linear guide rails are ensured; as the tool-measure device is additionally arranged on one side of one of the spindle milling cutter, tool measure for another time is not needed when the mortise of a same workpiece is machined or after the tool is replaced.

The invention discloses a steamed bread machine, comprising a steamed bread barrel, a barrel cover, a heating device, a stirring device and a stirring driving device. The barrel cover is arranged on the steamed bread barrel; An interlayer is provided between the outer barrel wall and the inner barrel wall, a raw material placement area is arranged on the inner side of the inner barrel wall, and the stirring device extends into the interior of the raw material placement area; an upper ventilation hole is provided at the upper connection between the outer barrel wall and the inner barrel wall, and the outer The bottom wall of the barrel wall is provided with a lower ventilation hole, and a water storage area is arranged below the outer barrel wall, and a steam channel is formed along the direction of the water storage area, the lower ventilation hole, the interlayer, the upper ventilation hole and the raw material placement area. In the present invention, the steamed bread barrel adopts a double-layered barrel wall structure, which makes the heat conduction more gentle, the steamed steamed bread surface is white, tender and smooth, the steamed bread inner flesh is soft and strong, and the taste is excellent.
