Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a valve structure for a dry cleaning machine for cleaning and drying dirt from clothes, futons, rugs, etc.

(b) Prior Art Conventionally, this type of valve structure has a rectangular valve structure as shown in FIG. In Figure 3,
Dry cleaning machine main body (hereinafter referred to as main body) 2
A valve seat 22 is formed in a rectangular shape on a partition plate 21 inside the main body 20, and a valve cover 24 is attached to one end of the opened main body 20 via a packing 23. An air cylinder 25 is fixed to the center of the valve cover, and a valve body 26 is attached to the tip of the air cylinder so as to be able to swing in one direction.
is provided. This valve body has a structure in which a stop 27 and a felt 28 are attached in a sandwich-like configuration, and the valve seat 22 is sealed by sliding the end face of the stop 28 onto a rail and swinging the valve body 26. was known (in 1987)
−168620).

(c) Problems to be solved by the invention With such a configuration, depending on the condition of the end face of the stopper when sealing the valve seat 22, there may be a malfunction in the valve body 26, resulting in malfunction. Sometimes,
Furthermore, since the valve body 26 is not held when the valve body is inserted, there is a problem that the valve body 26 does not come into close contact with the valve seat 22 accurately after the valve body 26 is inserted.

The object of this invention is to provide a valve structure for a dry cleaning machine that can improve the slidability of the valve body and prevent mounting errors when inserting the valve body.

(d) Means for solving the problem and its effect This invention consists of a rectangular valve seat installed in the dry air passage of the main body of the dry cleaning machine, and a valve seat that is moved to open and seal the valve seat for drying. a rectangular valve body for controlling passage of air; and a valve cover mounted in the dry air passage opposite to the valve seat and to which a cylinder for moving the valve body is fixed; Sliding fittings are provided on both sides of the end face, and the horizontal piece is L-shaped and extends integrally from the valve cover to allow the sliding fitting to slide, while the vertical piece consists of two opposing pieces, and the valve cover is placed in the dry air passage. When installing, the vertical piece and the valve body are inserted into the dry air passage with the valve body facing each other, and when the valve body contacts the valve seat, the valve body then slides on the horizontal piece through the sliding fitting in that position and remains. This is a valve structure for a dry cleaning machine in which a box-shaped valve body holder with vertical pieces extending close to both sides of the valve seat is fixed to the valve lid.

That is, in this device, after inserting the valve body, if the vertical piece is inserted into the dry air passage and passes the valve seat, it will closely straddle both sides of the valve seat, thereby changing the directionality of the valve body and the valve seat. By fitting the vertical piece and the valve seat, the directionality of the valve body can be ensured.Furthermore, by using a sliding metal fitting and a horizontal piece, the slidability of the valve body can be improved. This is intended to prevent installation errors in which the valve body is not held in place during insertion and does not come into close contact with the valve seat accurately.

(E) Examples This invention will be explained in detail based on the examples shown in the figures below. Note that this invention is not limited to this.

In FIGS. 1 and 2, the valve structure of the dry cleaning machine consists of a rectangular valve seat 3 constructed on a partition plate 1a disposed in a dry air passage 2 of a dry cleaning machine main body 1, and A rectangular valve body 4 that can swing in one direction to control the dry air passage 2 by opening and sealing the valve seat, and a rectangular valve body 4 that is mounted in the dry air passage 2 facing the valve seat 3 and moves the valve body 4. a valve cover 6 to which an air cylinder 5 is fixed;
Two-way sliding fittings 7 are provided on both sides of the lower end surface of the valve body 4, and a horizontal piece 8 of the L-shaped horizontal piece 8, which is fixed to the valve lid 6, extends integrally from the valve lid 6 and allows the sliding fitting 7 to slide. , and a box-shaped valve body receiver 10 consisting of two opposing vertical pieces 9.

Furthermore, the valve cover 6 is attached to one end of the opened main body 1 via a gasket 11, the air cylinder 5 is fixed to the center part of the valve cover 6, and the valve body 4 is attached to a stopper fixed in the shape of a sandwich. 12 and felt 13, and the valve seat 3 is sealed with this felt surface. The sliding metal fitting 7 is a stopper 1 that constitutes the valve body 4.
It is attached by screwing to both sides of the horizontal portion 12a bent into an L-shape of 2, and slides the horizontal piece 8 of the box-shaped valve body holder 10, that is, the sliding metal holder. The box-shaped valve body holder 10 integrated with the valve cover 6 is inserted into the dry air passage 2 with the vertical piece 9 and the valve body 4 facing each other when the valve cover 6 is attached to the dry air passage 2, that is, when inserting the valve body. When the valve body 4 contacts the valve seat 3, the valve body 4 slides on the horizontal piece 8 via the sliding fitting 7 and remains at the contact position.

On the other hand, the vertical piece 9 has two pieces 9a and 9b extending outward from the extension line of the horizontal piece 8 on both sides of the valve body 4 while maintaining a distance L (a<L) approximately equal to the width a of the valve seat 3. As mentioned above, before the valve body is inserted, the valve body 4 is in the inserted state, that is, the so-called face-to-face state. After inserting the valve body, if the vertical piece 9 is inserted into the dry air passage 2 in a face-to-face state and passes the valve seat 3, the vertical piece 9 will closely straddle both sides of the valve seat 3 with a width L. , constitutes a state in which the valve seat 3 is fitted.

That is, this vertical piece 9 allows the directionality (center) of the valve body 4 and the valve seat 3 to match when the valve body is inserted, and the directionality of the valve body 4 can be ensured by fitting the vertical piece 9 and the valve seat 3. Even if the valve body 4 is not held when the valve body is inserted, the valve body 4 can be accurately brought into close contact with the valve seat 3. Furthermore, by employing the sliding metal fitting 7 and the horizontal piece 8, even if there is some resistance, the valve body can slide smoothly and malfunction of the valve body can be prevented.

(f) Effect of the device As described above, according to this device, after inserting the valve body,
Since the vertical pieces of the box-shaped valve body holder are configured to fit close to both sides of the valve seat, the directionality of the valve body and valve seat can be matched, which ensures the directionality of the valve body and the valve seat. It has the effect of opening and closing the body accurately.
Furthermore, by using a sliding metal fitting and a horizontal piece, malfunction of the valve body can be prevented.
