First embodiment

Referring to fig. 1 to 3, the valve 001 according to the present embodiment includes a valve body 100 and a valve rod 200 embedded in the valve body 100, wherein an inner wall of the valve body 100, in which the valve rod 200 is embedded, is provided with an internal thread (not shown), and an outer surface of the valve rod 200 is provided with a corresponding external thread (not shown), and the valve rod 200 can rotate relative to the valve body 100 through a thread structure. Inside the valve body 100, two open pipelines penetrating the valve body 100 are arranged from the top to the bottom of the valve body 100, namely a first open pipeline 110 and a second open pipeline 111, and the valve rod 200 sequentially penetrates through each open pipeline and can rotate to different positions to control the two open pipelines to be opened and closed simultaneously.

It should be noted that the structure of the internal thread on the valve body 100 and the external thread on the valve stem 200 is to ensure that the valve stem 200 can rotate relative to the valve body 100 to control the valve body 100 to open or close, and should not be construed as limiting the present application; in other embodiments, a gear mechanism or other rotating member commonly known in the art may be used instead of the threaded structure.

It should be noted that the shape and the hole diameter of the two open conduits are not necessarily the same, and it is only necessary to ensure that the two open conduits penetrate through the valve body 100 and can be controlled to open or close by the valve rod 200 at the same time. For convenience of explanation, the two open pipes in this embodiment are parallel to each other, and the shape and the aperture are identical, and both are cylindrical.

The valve rod 200 may control the opening of the opening pipeline to be opened or closed simultaneously by forming a through hole or a special-shaped hole along the radial direction. In the present embodiment, the valve rod 200 is provided with two communication holes, namely a first communication hole 210 and a second communication hole 211, which are parallel to each other and penetrate through the valve rod along the radial direction, and are correspondingly arranged at the positions of the first opening pipeline 110 and the second opening pipeline 111; the valve stem 200 is provided with a knob 220 at a position outside the valve body 100, and a central axis of the knob 220 is parallel to the communication hole.

The first communication holes 210 can communicate with the corresponding first open conduits 110, and since the second communication holes 211 are parallel to the first communication holes 210 and the second communication holes 211 communicate with the second open conduits 111, it is ensured that the two open conduits are simultaneously in an open state, when the valve rod 200 is in the first position (see fig. 2). The valve rod 200 in the first position can control the two open pipelines to be opened simultaneously, and gas can circulate in the valve 001; if it is desired to close the valve 001, the valve rod 200 is rotated so that the communication holes do not communicate with the corresponding open pipes, i.e., the two open pipes are held by the valve rod 200, so that the open pipes are blocked by the valve rod 200 and gas cannot flow through the valve 001, and the valve rod 200 is in the second position (see fig. 3). Since the axis of the handle 220 is parallel with respect to the communication hole, whether the valve is in the open or closed state can be determined by observing the position of the handle 220. Taking this embodiment as an example, when the handle 220 is in the vertical state, the valve rod 200 is located at the first position, and the valve is opened (see fig. 2); when the handle 220 is at an angle to the vertical, such as in a horizontal position, the valve stem 200 is in the second position and the valve is closed (see fig. 3).

It should be noted that the shapes and the apertures of the two communicating holes are not necessarily completely the same, nor are they necessarily parallel to each other, and it is only necessary to ensure that the two communicating holes can be simultaneously communicated or not communicated with the corresponding open pipelines, so as to simultaneously open or close the two open pipelines.

Specifically, in the present embodiment, the two communication holes have the same shape, and the inner diameter of each communication hole is gradually reduced, when the valve rod 200 rotates to the first position, the communication hole communicates with the corresponding open pipe, and the inner diameter of the communication hole close to the top end of the valve body 100 is smaller, which is beneficial to reducing the occurrence of leakage accidents; the larger inner diameter near the bottom of the valve body 100 reduces the inflow rate of nitrogen gas and the occurrence of liquid splashing (see fig. 2). In addition, the inner diameter of each communication hole is not larger than the inner diameter of the corresponding opening pipeline close to the valve rod 200, so that the liquid leakage in the bottle can be reduced (see fig. 2).

Second embodiment

Referring to fig. 1 to 4, the storage bottle of the present embodiment includes a valve 001 of the first embodiment and a bottle body 002 with an opening at one end, the bottle body 002 can store hazardous liquid such as phosphorus oxychloride, and the valve 001 is disposed at the opening of the bottle body 002 for controlling the gas to flow in and out.

Two gas pipes 003 are arranged at the top end of the valve 001, and each gas pipe 003 is communicated with the valve 001 through an open pipeline respectively. The gas-supply pipe 003 can guide the flow direction of the outside gas of bottle 002, and one of them gas-supply pipe 003 can guide inert gas such as nitrogen gas to the inside of bottle 002 to contact with dangerous liquid such as phosphorus oxychloride, so that carry dangerous liquid's vapour in the inert gas, another gas-supply pipe 003 can guide the nitrogen gas that carries dangerous liquid vapour to specific place, conveniently takes the liquid in the bottle.

Still be provided with two breather pipes in the bottle 002, the one end of every breather pipe is connected with the bottom of valve 001 respectively, and two breather pipes communicate with valve 001 through two opening pipeline that correspond respectively moreover. The vent tube in the bottle body 002 can guide the flow direction of the gas in the bottle, ensuring that the inert gas can carry more vapor of dangerous liquid.

In this embodiment, the two ventilation tubes have different depths in the bottle body 002, wherein one of the two ventilation tubes is located at an end away from the valve 001 and closer to the bottom of the bottle body 002, which is the first ventilation tube 040, and the other ventilation tube 041 is shown in fig. 4. When the bottle body 002 contains liquid, the end of the first vent pipe 040 far from the valve 001 is inserted below the liquid level, and the end of the second vent pipe 041 far from the valve 001 is located above the liquid level. When the liquid in the bottle body 002 is taken out, the inert gas is introduced from the first vent pipe 040, the inert gas can be fully contacted with the liquid to carry more liquid vapor, then the inert gas carrying the liquid vapor flows out from the second vent pipe 041, and the second vent pipe 041 is positioned on the liquid surface, so that the situation that the liquid splashes out of the bottle can be reduced.

To sum up, the storage bottle of this application embodiment does not need specific operation order can take out the bottle with the liquid in the bottle outside, can greatly reduce the emergence that the condition was revealed to the interior material of bottle, not only is applicable to phosphorus oxychloride, also is applicable to other dangerous liquid.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
