Technical Field

The invention relates to a local component of a steamer furnace, in particular to a steam valve.

Background

The principle of the steamer furnaces for steaming steamed bread, steamed stuffed buns and the like in the current market is that water is basically added into the steamer furnaces, then the steamers provided with food are stacked, and then the water in the steamer furnaces is heated through a heating device, so that the food placed in the steamer is heated by utilizing the steam generated by heating the water. Such devices suffer from the following disadvantages: firstly, when the food does not exist in the steamer or the food is taken away, the steam and the fuel gas are used, so that unnecessary waste is caused; and secondly, the switches are manually controlled, so that the time of manual operation is increased. Therefore, an automatically opening and closing steam valve is used. At present, a steam valve with an automatic opening and closing function only comprises a steam inlet and a steam outlet, so that the steam valve can be only used at the end of a steam transmission path.

Disclosure of Invention

The invention discloses a steam valve, which is used for solving the problem that the existing steam valve can only be used at the end of a steam transmission path and needs to provide steam for a plurality of steaming chambers, and the structure is complex due to the large number of transmission paths.

In order to achieve the purpose, the invention adopts the following technical scheme:

a steam valve is provided with a steam inlet, a steam outlet, a blocking block for opening and blocking the steam outlet, and a steam delivery port.

Furthermore, the steam generator comprises a connecting pipe with two open ends, the two open ends of the connecting pipe are respectively a steam inlet and a steam transfer port, and the steam outlet is arranged on the side wall of the connecting pipe.

Further, including the rotatory pipe of quilt cover in the takeover with takeover threaded connection, the shutoff piece is regarded as the partly of rotatory pipe, thereby the takeover lateral wall is opened along circumference has spacing logical groove to expose the rotatory pipe, is equipped with the operation strip and inserts the rotatory pipe after passing spacing logical groove, thereby the operation strip moves along spacing logical groove outside the takeover and drives the rotatory pipe rotation and make the shutoff piece open and shutoff the vapour export.

Further, the operation strip is a screw, a screw hole is formed in the rotating pipe, and the screw is in threaded connection with the screw hole, so that the screw is fixed on the rotating pipe.

Further, the vapor outlet device further comprises a resetting mechanism, wherein the resetting mechanism applies resetting force to the blocking block to enable the blocking block to return to a position for blocking the vapor outlet.

Further, the reset mechanism is an elastic piece, and when the steam valve is opened, the elastic piece applies elastic force to the operating strip so as to enable the blocking block to return to a position for blocking the steam outlet.

Furthermore, the elastic piece is a deformable elastic piece, the deformable elastic piece is fixed on the outer wall of the connecting pipe through a fixing piece, and the deformable elastic piece blocks the operation strip to enable the operation strip to be located at the starting end of the limiting through groove, so that the blocking block blocks the steam outlet in a natural state.

Further, a sealing member is arranged at the external connection position of the steam inlet and/or the external connection position of the steam transfer port.

Further, the external connection position of the steam inlet and the steam transfer opening is a male-female structure, so that the steam transfer opening of one steam valve can be butted with the steam inlet of another identical steam valve.

Compared with the prior art, the invention has the beneficial effects that: through setting up the steam transfer mouth for steam that gets into in the steam valve from steam inlet can not only flow out from the steam outlet, can also pass steam from the steam transfer mouth, and further, when needing to provide vapour for a plurality of steam rooms, can set up a plurality of these steam valves on same steam transmission route and supply vapour for a plurality of steam rooms respectively, thereby reduced the quantity of steam transmission route, can simplify the structure.

Detailed Description

The invention is further illustrated with reference to specific embodiments and the accompanying drawings.

As shown in fig. 1, the steam valve 10 includes a connection pipe 1 and a rotary pipe 2 sleeved in the connection pipe 1, both upper and lower ends of the connection pipe 1 are open, the lower end of the connection pipe 1 is a steam inlet 17, the upper end of the connection pipe 1 is a steam transfer port 16, the bottom of the sidewall of the connection pipe 1 is provided with a steam outlet 11, steam entering the connection pipe 1 from the steam inlet 17 can flow out from the steam outlet 11, and can also flow into a steam pipeline or another steam valve from the steam transfer port. As shown in fig. 2, the inner wall of the adapter tube 1 is provided with an internal thread 12, the rotary tube 2 is in a circular tube shape, the outer wall of the rotary tube 2 is provided with an external thread 13 matched with the internal thread 12, the rotary tube 2 is connected with the adapter tube 1 through the external thread 13 and the internal thread 12, so that the joint of the rotary tube 2 and the adapter tube 1 has high sealing degree, steam cannot leak from the joint of the rotary tube 2 and the adapter tube 1, and the rotary tube 2 can rotate in the adapter tube 1. The blocking block 21 is used as a part of the rotary pipe 2, the blocking block 21 rotates along with the rotary pipe 2, the area of the blocking block 21 is slightly larger than that of the steam outlet 11, the blocking block 21 rotates to the position of the steam outlet 11 in the process of rotating along with the rotary pipe 2 to block the steam outlet 11, and when the blocking block 21 rotates along with the rotary pipe 2, the blocking block 21 is gradually moved away from the steam outlet 11, so that the steam outlet 11 is opened, and steam flows out of the steam outlet 11.

As shown in fig. 1 and fig. 2, a position on the adapter tube 1 contacting with the rotating tube 2 is provided with a limiting through groove 14 penetrating through the side wall of the adapter tube 1, the limiting through groove 14 is arranged along the circumferential direction of the adapter tube 1, a screw hole 22 is arranged on the rotating tube 2 opposite to the limiting through groove 14, a screw 3 serving as an operation strip passes through the limiting through groove 14 and then is in threaded connection with the screw hole 22, the tail end of the screw 3 is fixed on the rotating tube 2, the head end of the screw 3 is exposed on the outer wall of the adapter tube 1, so that when external force acts on the head end of the screw 3, the screw 3 moves along the limiting through groove 14, thereby driving the rotating tube 2 and a plugging block 21 connected with the rotating tube 2. When the screw 3 is located at the starting end 141 of the limiting through groove 14, the blocking block 21 just blocks the steam outlet 11 (see fig. 3), the screw 3 moves from the starting end 141 of the limiting through groove 14 to the ending end 142 of the limiting through groove 14, the blocking block 21 gradually opens the steam outlet 11, and when the screw 3 moves to the ending end 142 of the limiting through groove 14, the blocking block 21 just completely moves away from the steam outlet 11, so that the steam outlet 11 is completely opened.
