Description

[Detailed Description of the Invention] In the current JPJK technique, a disk valve that closes completely is not easy to open and close, while a disk valve that is easy to open and close is difficult to close completely. Generally true. In fact, one of the main causes of current disc valve failures is that the sole placed between the disc and the valve body is damaged due to wear and tear during operation. y〕
Occurs in '1: f leakage 33 This problem occurs when the disc valve has a high 113 or 1111 temperature I) L <?;tIt is a serious matter when applying both.

The main object of the present invention is to provide a disc valve that closes completely and at the same time opens and closes easily.

Another object of the present invention is to provide a disc valve that does not experience wear during opening and closing cycles on a resilient sole located between the valve disc and a mating valve seat located on the valve body.

1-1 of one of the songs of the invention): J: When the valve stem moves in either direction parallel to its central axis, it moves towards or away from the mating annular valve seat located on the valve disc and valve body. The disc valve is designed to create a seating pressure that closes the valve disc to completely prevent leakage due to the movement of the valve disc and the valve seat of the valve body, or to release such pressure so that the valve disc can be rotated easily. It is to provide.

Another object of the invention is to provide a disc valve in which the valve body is provided with an annular valve seat that conforms to a generally spherical surface.

Another object of the invention is to provide an entire disc valve that includes a disc with a spherical rim surface.

Another object of the invention is that the valve disc is attached to the valve stem.
They are connected in such a way that rotational movement in all planes is prevented, although slight line movement occurs between them in a plane that includes the center line of the valve disk and the center line and axis of the well stem. To provide a disc valve.

Another object of the present invention is to create a seating pressure between the valve disk and the valve body (3), and to release the force. To facilitate movement of the seat in either direction parallel to its axis, a disc tP ft includes cam means, a jack screw hand or a lever means connected to the body.
It is to provide IM.

Another feature of the history of the invention is that when the valve stem moves slightly, the square disk approaches the mating annular valve seat.
．． We propose a disc valve that is located at a distance from the valve stem or pivoted slightly to create a seated pressure between the valve stem and the JP seat, and to release such pressure1↓
(It is to be.

These and other objects of the present invention will become clear as the description of the present invention progresses. The invention will be described in detail below with reference to the accompanying drawings.

In FIG. 1, the universal disc valve according to the VC of the present invention is shown in the fully closed position with a cross section along a plane including the central axis of the fluid passage and the line inside the stem. It is shown cut away. Universal disc valve 1 is 7711

14) A hollow cylindrical valve body 2 having a pair of connecting means 4.5.
Contains. The valve body 2 also includes an annular valve seat 6 disposed in a plane substantially perpendicular to the central axis of the fluid passage 3 , the surface of the annular valve seat 6 having a diameter approximately equal to the diameter of the fluid passage 3 and extending from the center of the fluid passage 3 . It conforms approximately to an imaginary spherical surface 7 which is approximately centered on the axis (rj) and is offset from the plane in which the annular valve seat is located.

A valve disc 8 in the form of a generally flat round disc with a rim surface 9 approximately corresponding to an imaginary spherical surface 7 is rotatably disposed in the fluid passageway in the vicinity of the annular valve seat 6 and is attached to a stem 10, the stem being aligned with the central axis of the disc 8. The stem 10 is connected in such a manner that it can move relative to the disk in a direction substantially parallel to the surface of the disk 8 in a plane including the center axis of the stem 10 and the disk 8, but that no relative rotation occurs between the disk and the stem. There is.

Such a connection between the disc 8 and the stem 10 is achieved by means of a dovetail groove or the like provided in the depending member 11 of the disc 8 to receive in sliding relationship a corresponding structure provided at the inner end of the stem 10. This is done by using a holding sliding groove, and a specific example of this connection will be described and explained with reference to FIG. Ste A 1
() extends through the hole 13 in rotatable and slidable engagement with the elastic ring seal 14 to completely prevent leakage, and the central axis of the stem passes approximately through the center +ll+ line of the 0 imaginary ball 7. The outer end 15 of the stem 10 has a pin rotatably engaged with a through hole 18 provided in the stem 101C near the outer end 15 of the stem 10. 17 to the cam means 16. The pin 17 is connected to a pair of eccentric cam rollers 19 and 20 which sandwich the outer end 15 of the stem 10, and this pair of cam rollers are connected to the cam housing 220. - It is trapped between the L surface and the lower surface 23 of the overhang part 24 extending from the base of the cam housing 22. The cam housing 220 base is detachably attached to the stem housing 25 extending from the valve body 3. A pair of eccentric cam rollers 19,20 are attached to the forked end 2 of the handle 27.
Take each of 6 (=J ke).

In FIG. 2, the universal disc valve l shown in FIG. 2 is shown in end view in the fully open position. Forked end 26 of handle 27
A pair of eccentric cam rollers 19.2 (
The structure of the cam means 16 including lr is shown in detail in FIG. It is necessary to explain that FIG. 2 shows the cam means 16 in a position rotated approximately 90 degrees from its actual position to an imaginary position, and that this displacement of the cam means makes the cam means more clearly visible. This is to explain.

When the universal disc valve 1 has the structure shown in FIGS. 1 and 2, the universal disc valve 1 functions as follows. When the handle 27 is turned to one extreme position in a pivoting motion about the center of the bottle 17, in the fully closed position shown in FIG. When the valve stem 10 is moved in this manner, the disc 81r is pushed toward the annular valve seat 6 to align the valve seat 6 of the valve body 2 and the rim 9 of the disc 8 to prevent leakage. When the handle 27 is turned to one extreme position that completely closes off the universal disc valve 1, the overhang member 24 allows the forked end 26 of the handle 17 to close to the stem 10.
(17) [2, thus the disc 8 remains locked in the fully open position. When the disc valve is at the fully closed position t# shown in FIG.
It should be understood that it is generally unnecessary to rotate the disc 8 without damaging the seating surface even if the disc 8 is not restrained from rotating about the central axis of the stem 10 by the disc 4. To open the universal disc valve 1, the handle 27 is turned to the other extreme position opposite to that shown in FIG.
moves to pull out the stem 10 a small distance from the valve body 2 and separate the rim 9 of the disc 8 from the valve seat 6 of the valve body, and in this state the disc 8 floats and can be rotated very easily. Handle 27? : When the universal disc valve is turned to the fully open position around the center axis of the stem 1O, one side of the fork-shaped end 26 of the handle 27 comes into contact with the bottom of the overhang Hn 24, and the disc 8 is automatically opened. The city will be stopped at

To improve the performance of the universal disc valve l, one or both of the valve seat 6 of the valve body (8) 2 and the rim 9 of the disc 8 can be lined with a hard wear-resistant material. Of course, the valve seat 6 of the valve body 2 and the rim 9 of the disk 8 may be formed integrally with the valve body 2 and the disk 8, respectively, or may be inserted or glued into the valve body and the disk, respectively. is clear. Valve stem 10 used in the universal disc valve of the present invention
The first angle between the center '1fll line and a plane parallel to the disk 8 is 0° depending on the structure and operating conditions.
Grouped with one set of angles with a range of 1■ greater than or equal to 45 degrees or less. In general applications, oblique angles in the range of 106 or more to 15 degrees provide certain advantages in snubbing the valve and making it easier to operate. Fully close and fully open the valve by closing the handle on the center L of the valve stem and the axis line all the way L.
The angle of rotation between the i-spaces is a function of the oblique angle and is equal to the inverse cosine of the oblique angle minus the square of the tangent. The analogy is 1
For a diagonal angle of 5 degrees, it is necessary to turn the stem 9.41 degrees, for a diagonal angle of 30 degrees it is necessary to turn the stem 10.9 degrees, and for a diagonal angle of 45 degrees it is necessary to turn the stem 180 degrees. between the mark vector of the plane containing the central axis of the valve stem and the center lql+ line of the annular valve seat of the valve body and the standard vector I of the plane containing the face of the disk turned to the fully open position.

A common principle teaches the use of different t-stages to vary the seating pressure and different means of sealing between the valve seat and the disc to prevent leakage. It can be applied to the manufacture of many other swivel disc valves. A swivel disc valve that applies the basic principle of assembling the disc, disc, and stem shown in Figures 1 and 3 has the advantage that this valve can use a one-piece disc and that the swivel disc is very easy to assemble. It offers the advantage of being able to be assembled and disassembled. The universal disc valve can be assembled by first positioning the disc in the appropriate position within the valve body and then inserting the valve stem through the hole in the stem housing and through the slot 17 in the flap member of the disc. A cam or jack screw means is connected to the stem housing to complete assembly of the universal disc valve. The universal disc valve is easily disassembled by reversing the order of the assembly steps. It should be mentioned that lever means can be used instead of cam means or jack screw means to move the stem a small distance in the axial direction.

Pivoting movement of the handle about the central axis of the pin 112 causes a slight axial movement of the stem 107, and this movement of the stem causes the disk to move relative to the stem and the corresponding valve seat provided on the disk and valve body. It is understood that the cam means shown in Figure 13 is merely illustrative of the use of a cam mechanism to cause slight linear movement of the stem. Many other cam designs can be used that produce the same result.

FIG. 14 shows a universal disc valve 119 having a short upright stem 120 in cross-section.

The valve body 121 with the annular valve foot 122 and the disc 123 are arranged and arranged in the same manner as in the universal disc valve 84 or 104 shown in FIGS. 9 or 12. The disk 128 includes a pivot pin 124 having a generally hemispherical end 125 extending radially from one side of the disk 128 near the rim surface 126, with the center of the pin 124 disposed generally parallel to the surface of the disk 1230. The axis is offset from the plane containing the plane of the disk (33) 128. An extension of the center line 1111 of the pivot bin 124 substantially passes through the center of an imaginary spherical surface that substantially includes the surface of the annular valve seat 122. Pivot bin 124 is rotatably engaged in a hole 127 provided in valve body 121, which hole 127 has a tapered wall on one side, so that pivot bin 124 is connected to the central axis of pivot bin 124 and fluid passageway 12B. It can be tilted at a reasonable angle with respect to the plane containing the central axis of the plane.

The outer end of the short stem 120 is adapted to be connected to screw or cam means such as those shown in FIG. 1 and FIG. 12, respectively. When the short stem 120 is pulled out a short distance, the depending member 129 attached to the disc 123 moves one inch into the stem, while the pivot pin 124 remains in the hole 127, so that the disc 123 is approximately within the pivot pin 124. It makes a slight tilting movement about the center of the hemispherical end 125. Hanging member 1
A retaining slide joint, such as a dovetail slide joint 131 connecting 29 to the short stem 120, is such that the disc 123 is lifted a small distance toward the stem 120 when the stem 120 is pulled out such a small distance. Yes, such a lifting movement
This is done by a stopper 135 provided at. Pivoting of the disc 128 about the center of the generally hemispherical end 125 of the pivot bin 124, in combination with slightly lifting the disc 123 by pulling out the short stem, causes the rim 126 of the disc 123 to become tL-shaped. Valve seat 1

42 and the valve seat 138 will be closed to ensure tight contact and prevent leakage. The stem housing 150 is provided with a slot-like opening 162 having a recess t68 for accommodating a bottle 164 extending into the first short stem 143. The seating surface between the rim 142 and the valve seat 138 also acts to protect against damage as a result of relatively forced rotation without relieving the seating pressure between them;
This damage protection principle will be explained from 1 to 1 with reference to FIG.

While the principles of the invention have been illustrated by the description of an illustrative example, it is obvious that various changes may be made in structure, components, proportions, and arrangement to be particularly suited to a particular working environment without departing from the principles of the invention. I think it would be easy for entrepreneurs to come up with this idea.
