Description

Technical field The invention relates to a component for inflating and deflating, in particular a tire valve. State of the art The tire valve is mounted on the rim and protrudes from it for inflation or deflation. Conventional tire valves have a valve stem in the valve seat. The valve stem is fitted with a valve core to control the flow of air, ensuring the tire maintains a specific pressure. The stem of a conventional tire valve has a large-diameter tube section. This provides a larger airflow space for the valve core, resulting in a higher airflow rate. When the conventional tire valve is mounted on the rim, the large-diameter tube section of the valve stem passes through the rim and remains outside the rim. The protruding part of the valve stem must be secured with a nut and also includes a connecting section for the air pump. Therefore, the conventional valve stem has a large axial dimension, which significantly increases the overall length of the conventional tire valve and makes it susceptible to breakage from external forces. For this reason, it is necessary to provide a novel and advanced tire valve to solve the aforementioned problems. Object of the invention The object of the invention is to provide a tire valve that can shorten the overall length and reduce the risk of breakage due to external forces. This objective is achieved by the tire valve of the invention, which comprises: a tube having an inner surface, an inner channel and a first thread, wherein the inner channel is defined by the inner surface; a valve insert containing a sealing element and movably arranged in the inner channel, wherein the valve insert can be actuated such that the sealing element rests against the inner surface and thereby closes off the inner channel or the sealing element does not rest against the inner surface and thereby does not close off the inner channel; and a cap having an opening and a second thread that is screwed onto the first thread, wherein the cap presses against the rim to secure the tire valve to the rim, the opening communicating with the inner channel and serving for a detachable connection with an inflation and deflation device.

Ways to implement the invention The following embodiments serve only to illustrate possible implementations of the present invention and are not intended to limit the scope of the present invention. 1 to 4 Figure 1 shows an embodiment of the present invention. The tire valve 1 of the invention comprises a tube 10, a valve insert 20, and a cap 30. The tire valve 1 can be, for example, a Schrader valve, a Presta valve, or a UK valve. The tube 10 can be a one-piece or multi-piece component. The tube can have a valve body and a valve stem. The valve body and the valve stem can be formed as a single piece. The valve body is the part that is connected to a rim, and the valve stem is the part that is connected to the valve body and protrudes from the rim. The pipe 10 has an inner surface 11, an inner channel 12, and a first thread 13. The inner channel 12 is defined by the inner surface 11. The valve insert 20 contains a sealing element 21 and is movably arranged in the inner channel 12. The valve insert 20 can be actuated such that the sealing element 21 rests against the inner surface 11, thereby closing off the inner channel 12, or the sealing element 21 does not rest against the inner surface. The cap 30 rests against the rim 11 and thus does not block the inner channel 12. The cap 30 has an opening 31 and a second thread 32, which is screwed onto the first thread 13. The cap 30 presses directly or indirectly against the rim 100 to secure the tire valve to the rim 100. The opening 31 communicates with the inner channel 12 and serves for a detachable connection to an inflation and deflation device. In this way, the tube 10 does not protrude from the rim 100, or only partially, thus significantly shortening the overall length of the tire valve and reducing the risk of breakage due to external forces. The tube 10 also features a large-diameter tube section 14 through which the inner crescent 12 extends. This large-diameter tube section 14 provides a larger airflow space between the tube 10 and the valve insert 20 to achieve a higher airflow rate. When the tube 10 is installed in the rim 100, the large-diameter tube section 14 penetrates the interior 101 of the rim 100. The sealing element 21 rests
