The valve body 10 has an internal space forming a channel, and a pipe can be connected to both sides of the valve body 10. To this end, a coupling nut 90 may be mounted on each side of the valve body 10. The valve body 10 is not limited to the above-described two sides, and may include three or four pipes connected to each other.

The ball 20 is mounted in the internal space of the valve body 10 and an orifice 22 is formed to selectively open and close the conduit.

A stem 30 is coupled to the upper part of the ball 20. The ball valve according to an embodiment of the present invention has a structure in which the ball 20 and the stem 30 are separately connected to each other. However, it should be understood that the present invention is not limited thereto, and that a ball stem having the function of the ball 20 and the stem 30 that selectively open and close the channel may be applied.

Meanwhile, a handle (not shown) for rotating the stem 30 is coupled to the stem 30, and when the handle is rotated clockwise or counterclockwise at a predetermined angle, the channel of the valve body 10 is opened , And returning the handle in the opposite direction operates in such a way that the channel of the body 10 is closed.

In order to solve the problem of damaging the seat 40 due to friction generated between the ball 20 and the seat 40 during the operation of the handle, So that the lubricant can be automatically injected into the engine.

In order to achieve the above object, according to the present invention, a cam (50) installed on the stem (30) and rotating when the stem (30) rotates is rotatable, and a rear end supported by the cam A piston 60 which is compressed by the shape of the cam 50 and a lubrication oil cylinder 70 which contains the piston 60 and supplies the lubricating oil by the operation of the piston 60, And a lubricant storage tank 80 in which lubricant oil to be supplied to the lubricant storage tank 80 is stored.

The cam 50 is symmetrically formed on both sides of an axis of the stem 30. The piston 60, the lubricant cylinder 70 and the lubricant storage tank 80 are disposed on opposite sides of the cam 50, As shown in FIG. In the present invention, as shown in FIG. 2, it is proposed that the cam 50 has an approximately elliptical shape.

The cam 50 supports the piston 60 in contact with the rear end 62 of the piston 60. That is, the rear end portion 62 of the piston 60 is supported by the cam 50 so that the cam 50 is compressed by the shape of the cam 50 when the cam 50 rotates.

In the present invention, the piston (60) may be provided with a spring (110) for restoring the piston (60) compressed by the cam (50). The rear end 62 of the piston 60 has a flange shape so that the spring 110 is supported between the rear end portion 62 of the piston and the outer wall of the lubricant cylinder 70, 60, respectively.

When the piston (60) is compressed by the shape of the cam (50), the spring (110) is also compressed. When the cam (50) The rear end 62 of the piston 60 is pushed by the piston 60 so that the piston 60 can be restored to its original state.

A plurality of grooves 64 are formed on the outer circumferential surface of the piston 60 inserted into the lubricant cylinder 70. The groove 64 is formed to reduce the friction between the piston 60 and the inner wall of the lubricant cylinder 70. The groove 64 is formed around the outer circumferential surface of the piston 60, 64, an O-ring 66 is inserted for sealing.

It is preferable that the lubricant cylinder 70 is disposed below the lubricant storage tank 80 so that the lubricant stored in the storage tank 80 can be introduced into the cylinder 70 by gravity. An outlet is formed in the lubricant storage tank (80) and the lubricant cylinder (70) to supply lubricant to the lubricant cylinder (70) in the tank (80).

The outlet is located outside the stroke of the reciprocating movement of the tip of the piston (60) so that hydraulic pressure can be applied by the movement of the piston (60).

A ball 76 elastically supported by a spring 74 is installed on the outlet so that the outlet can be opened or closed according to the operation of the piston 60. In this case, the outlet is provided with a hollow end stop 72, and the spring 74 is seated on the upper surface of the end stop 72.

The end stop 72 also serves to prevent the leading end of the piston 60 from coming in when the piston 60 reciprocates. That is, when the piston 60 is compressed and moved inside the lubricant cylinder 70, the tip of the piston 60 is caught by the end stop 72, so that the piston 60 is no longer operated. For this, as shown in the enlarged view of FIG. 1, the end stop 72 may be formed in a shape such that the one surface thereof protrudes by a predetermined amount.

The outlet port of the lubricant storage tank 80 is provided with a release port 82 for preventing the ball 76 from being disengaged. The separation chamber 82 is hollow to form a passage through which the lubricant can be supplied. The hole formed in the separation chamber 82 is smaller in diameter than the diameter of the ball 76, (76).

An outlet port for supplying the lubricating oil in the lubricating oil cylinder 70 to the seat 40 is formed on the lower surface of the lubricating oil cylinder 70.

The outlet port is formed to communicate with the first flow path 12 formed in the valve body 10.

That is, the valve body 10 of the present invention is provided with a first flow path 12 for supplying lubricating oil in the lubricating oil cylinder 70 to the seat 40, And a second flow path 42 for supplying the lubricant supplied from the ball 12 to the contact surface between the ball 20 and the seat 40 is formed.

The second flow path 42 is connected from the first flow path 12 to the contact surface of the seat 40. Although the second flow path 42 is shown in an 'a' shape in the drawing, the present invention is not limited to the shape of the second flow path 42, and may be applied in various forms.

A ball 18 formed at the lower end of the lubricant cylinder 70 and connected to the first flow path 12 is provided at a lower end thereof with a spring 16, The outlet may be opened or closed.

It is preferable that a groove 14 into which the spring 16 can be inserted is formed in the valve body 10 for installing the spring 16 and the ball 18. In this case, it is needless to say that the groove 14 is formed to communicate with the first flow path 12.

A discharge port 78 is provided in an outlet formed in the lower surface of the lubricant cylinder 70 to prevent the ball 18 from being released. Is smaller than the diameter of the ball (18) to prevent the ball (18) from being detached.

Meanwhile, it is preferable that the releasing chamber 78 also serves as an end stop for preventing the tip of the piston 60 from coming in when the piston 60 reciprocates. Therefore, as shown in the drawing, the one surface is formed to protrude by a predetermined amount, so that the tip of the piston 60 is caught by the escape region 78, so that the piston 60 can no longer operate.

FIGS. 3 to 5 are views showing steps of injecting lubricating oil into the ball valve of the present invention, and FIGS. 6 to 8 are views showing steps of charging the lubricating oil into the lubricating cylinder in the ball valve of the present invention The process of supplying the lubricating oil during the operation of the ball valve of the present invention will be described with reference to FIG.

3 is a cross-sectional view showing a state in which the orifice 22 of the ball 20 is opened so that fluid can flow through the pipeline. The cam 50 has a short radius on the rear end 62 of the piston 60 (Fig. 3 (b)).

4 (b)), the ball 20 is rotated so that the orifice 22 of the ball 20 is gradually closed (FIG. 4 (b)), do.

Simultaneously, the piston 60, to which the rear end portion 62 is supported by the cam 50, is gradually moved into the lubricant cylinder 70 while being compressed according to the shape of the cam 50.

Therefore, the pressure inside the lubricating oil cylinder 70 becomes higher than the pressure inside the outlet of the lower portion of the lubricating oil cylinder 70 and the lower portion of the lubricating oil storage tank 80, and by this oil pressure, The ball 16 of the spring 16 is separated from the hole of the releasing chamber 78 while the spring 16 provided on the outlet of the lubricating oil chamber 70 is compressed toward the first flow path 12, 70 is opened and a spring 74 provided at an outlet formed in the lower surface of the lubricant storage tank 80 is expanded toward the release chamber 82 and the ball 76 of the spring 74 is expanded, The outlet of the lower surface of the lubricant storage tank 80 is closed in a chain.

Therefore, the lubricating oil charged in the lubricating oil cylinder 70 flows into the first oil passage 12 through the outlet (enlarged view of FIG. 4).

Since the first flow path 12 is in communication with the second flow path 42, the lubricant is supplied between the ball 20 and the sheet 40 through the second flow path 42.

When the operation of the handle is completed, the piston 60 moves to the position of the end stop 72 and completes the compression. Thus, the channel of the ball valve is closed and the supply of the lubricant is stopped (FIG.

Then, when the handle is rotated in the counterclockwise direction in the figure to open the ball valve, the ball 20 is rotated in the counterclockwise direction as shown in FIG. 7, 20 are gradually opened.

At the same time, the piston (60) is moved in the opposite direction according to the shape of the cam (50) by the restoring force of the spring (110) fitted in the piston (60).

Therefore, the pressure inside the lubricant cylinder 70 becomes lower than the pressure inside the lower surface of the lubricant cylinder 70 and the inside of the outlet formed in the lower surface of the lubricant storage tank 80, and by this vacuum pressure, The spring 74 provided at the outflow port formed on the lower surface of the discharge port 80 is compressed toward the lubricant cylinder 70 so that the ball 76 of the spring 74 is separated from the hole of the release port 82, A spring 16 provided at an outlet formed on the lower surface of the lubricant cylinder 70 is expanded toward the release cushion 78 and is urged toward the ball 18 of the spring 16, And the outlet of the lower surface of the lubricating oil cylinder 70 is closed.

Therefore, the lubricating oil stored in the lubricating oil storage tank 80 flows into the lubricating oil cylinder 70 through the outlet, so that the lubricating oil is charged into the cylinder 70.

When the operation of the handle is completed, the piston 60 also completes its movement, and the position of the piston 60 is fixed by the lubrication force of the spring 110. Thus, the channel of the ball valve is opened, (Fig. 8).

Thereafter, as described above, according to the operation of the handle, the piston 60 is actuated and lubricant is automatically supplied between the balls 20 and the seat 40.

As described above, according to the present invention, lubricant can be automatically injected into the contact surface between the seat 40 and the ball 20 together with the opening and closing operation of the handle, thereby preventing heat and abrasion due to friction.
