Embodiment 1

[0025] The self-closing valve for preventing liquid from overflowing when the container is toppled over includes a valve body 1, a valve seat 2, a spherical disc 3, a valve stem 4, a valve stem sleeve 5, a universal three-dimensional cam 6, a bearing frame 7, and a bearing sleeve 8 , universal cam connecting rod 9, ball bearing 10, weight connecting rod 11, spherical weight 12, the above structure has the same central axis from top to bottom, as figure 1 and figure 2 As shown, the valve body 1 and the valve seat 2 are an integral structure, the center of the valve seat 2 has an inlet and outlet 21, its upper and lower end surfaces are both inner conical surfaces, and its lower end surface can form a linear contact seal with the spherical valve disc 3 ; On the valve body 1, the part below the valve seat 2 and installed in the container 13 has more than one inlet and outlet 22, such as figure 2 As shown, the valve disc 3 is fixedly connected with the valve stem 4, the lower e...

Embodiment 2

[0031] This embodiment is a self-closing valve with an exhaust valve, that is, on the basis of the structure of Embodiment 1, an exhaust valve is added, and the exhaust valve falls on the inlet and outlet 21 of the upper end surface of the valve seat 2. The sealing ball 17 is in close linear contact with the upper end surface of the valve seat 2; in order to prevent external pollution, the device also includes a cover body 15 and a silk screen 18, and is located on the valve body 1 above the valve seat 2. There is an air outlet 16; the cover body 15 is installed and fixed on the upper part of the valve body 1, and the silk screen 18 is sealed on the lower part of the cover body 15, forming a breathable protective cover together with the cover plate, and the air outlet hole 16 is sealed therein.

[0032] Install the device on containers containing volatile liquids, such as image 3 and shown in Figure 4. After pouring into the volatile liquid, close the valve 19 on the top to ...

Abstract

The invention relates to a self-closing valve capable of preventing liquid overflowing when a container falls down, which comprises a valve mechanism. The self-closing valve is characterized in that the valve also comprises a supporting mechanism and a swing mechanism, and the valve mechanism, the supporting mechanism and the swing mechanism are symmetrically distributed on the same central axis line from top to bottom; when a container falls down, the swinging of a heavy hammer drives a ball bearing to rotate, so that a universal vertical cam is driven to perform corresponding swinging to jack up a valve stem and a valve clack, and the valve stem and the valve clack form compact surface contact or line contact before the content in the container is spilled out to seal the inlet/outlet port on a valve base. The inventive self-closing valve effectively solves liquid overflowing problem when the container falls down, and avoids many troubles due to failing to close the container filled with liquid or closing behind time by an operator; and also effectively solves the collection and storage problems of volatile liquid by arranging an exhaust valve. Therefore, the inventive self-closing valve has simple structure, and can be widely used in places requiring automatic prevention of liquid overflowing when the container falls down or prevention of volatilization and sputtering of volatile liquid.

Description

technical field [0001] The invention relates to a valve, in particular to a self-closing valve for preventing liquid from overflowing when a container is toppled over. Background technique [0002] Some animal breeding bases, animal protection and research institutions, or places such as zoos often collect animal urine on a regular or irregular basis for various needs, but it is not necessary or impossible to specifically restrict the free movement of animals for this purpose , thus often cause the collection container to be overturned and spilled by animals consciously or unconsciously, which affects or delays the collection work. For another example, in some occasions, due to some liquids that may be used anytime and anywhere, it is packed in a container, and the lid will be tightly closed, which will cause trouble for taking it at any time. Containers for holding liquids will also cause the above-mentioned overturning events due to forgetting to cover the lids after use,...
