Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a check valve for a small-

The present invention relates to a check valve for a small-sized pressure vessel, and more particularly, to a check valve of a small-sized pressure vessel, in which a valve shaft of a valve plate is inserted into a valve body to be fastened to the vessel, To a check valve of a small-sized pressure vessel in which the valve plate can be coupled to the valve body without a simple structure and the assembling property is improved.

In general, a dispenser is combined with an opening of a container containing contents such as liquid cosmetics, detergents, and various insecticides such as detergents and mosquito repellents so that the contents can be discharged and used. Such a dispenser is disclosed in Japanese Patent No. 1022618, A piston coupled to the upper end of the cap and coupled to the lower end of the stem, a piston coupled to the upper end of the cap and having a nozzle, a stem coupled to a lower portion of the button, a piston coupled to a lower end of the stem, And a check valve in the form of a ball mounted inside the cylinder to close and open the lower opening. When the cylinder is depressed while pushing the button, the contents inside the cylinder are released to the piston Through the formed inlet and the internal passageway of the stem through the nozzle And the check valve closes the opening of the cylinder. On the contrary, when the button is released, the stem and the piston rise due to the elasticity of the spring which has been compressed. Since the check valve is opened in this process, the contents inside the container are introduced into the cylinder, I have to wait.

However, the conventional check valve is configured in the form of a spring and a ball, and a structure for catching the spring and the ball is required, so that the structure is complicated.

The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a valve body for an internal combustion engine in which a valve shaft of a valve plate is inserted into a valve body fastened to a container, The valve plate can be coupled to the valve body without a tool, thereby providing a check valve of a small-sized pressure vessel in which the structure is simple and the assembling property is improved.

In order to achieve the above object, the present invention has a valve body which is fastened to a small container through a thread, and a valve plate having a valve shaft fitted in a passage of the valve body is fitted to a packing of the valve body, A check valve of a container, wherein an end of the valve shaft is provided with a stopping jaw on both sides, and a cutout is formed between the stopping jaws; Wherein the valve body is provided with a discharge port having a diameter smaller than that of the passage so that the valve shaft is inserted into the valve body. When the cutout of the valve shaft inserted in the passage is opened to both sides, the engagement protrusions are opened, And is fastened to the valve body.

The present invention is intended to prevent the valve plate from being separated from the valve body by inserting the valve shaft of the valve plate into the valve body constituting the check valve and then fixing the valve shaft to the valve body so that the valve shaft is conventionally fixed by being protruded to the outside of the valve body It was bulky and it was troublesome to fasten to the container.

In order to solve this problem, the present invention is characterized in that the end of the valve shaft of the valve plate is cut so as to be divided into both sides, and the both ends of the valve plate are formed with a stopper. Therefore, when the valve shaft is inserted into the inside of the valve body, and the gap between the engaging jaws is widened by opening the both sides of the valve body, the engagement protrusions are caught in the valve body, and the valve plate is coupled to the valve body. There is an advantage that the structure can be simplified and the valve shaft can not be protruded to the outside of the valve body, so that the volume can be reduced.

1 is a perspective view of a check valve according to an embodiment of the present invention;
Fig. 2 is a view showing an assembling flow chart of the check valve of the present inventive embodiment
3 is a cross-sectional view of the check valve of the present inventive embodiment

1 to 3, the check valve is formed with a thread 13 on the outer peripheral surface of the valve body 10 to fix the valve body 10 inside the small-sized container. A passage 11 through which the liquid flows is formed inside the valve body 10 and a discharge port 12 having a diameter smaller than that of the passage 11 is formed on one side of the sieve passage 11. [

A valve shaft 20 is formed at the center of the valve plate 20 so that the passage 11 is formed along the discharge port 12, . The valve shaft 21 is formed in a conical shape having a smaller diameter toward the end so that the gap between the outer circumferential surface of the valve shaft 21 and the inner circumferential surface of the discharge port 12 in a state in which the valve shaft 21 is fitted in the discharge port 12 Thereby providing a space through which liquid can flow.

The end of the valve stem (21) is formed with an engagement protrusion (22) which is split on both sides by a cutout (23). The valve body (10) is provided on the outer circumferential surface thereof with a packing (14) in close contact with the valve plate (20).

The present inventive embodiment thus constructed is assembled as in Fig. First, the valve shaft (21) of the valve plate (20) is inserted into the discharge port (12) and is pushed into the passage (11). Thereafter, a separate tool is inserted into the passage 11 and the cut-out portion 23 is widened on both sides so that the engagement protrusions 22 are separated from each other. At this time, the stopping jaws 22 are opened and the valve shaft 21 is fixed to the inside of the passage 11 in a state in which the stopping jaws 22 are engaged with the discharge port 12. As a result, the valve plate 20 is assembled with the valve body 10 engaged.

In this state, when the valve body 10 is fastened to the container through the thread 13, the valve plate 20 is pressed by the liquid pressure inside the container and is brought into close contact with the packing 14, so that leakage of the liquid is prevented. In this state, when a rod (not shown) inserted in the passage 11 is pressed, the valve shaft 21 is pushed, the valve plate 20 is separated from the packing 14, and the liquid is discharged from the discharge port 12 to the passage 11 And is sprayed outside. At this time, since the latching jaw 22 is opened, the valve plate 20 is held in the discharge port 12, so that the gap between the valve plate 20 and the valve body 10 is kept constant.
