Description

An airtight slide gate is designed for use in the field of radioactive and toxic substances overload, it can be used to open and close penetrations between chambers and boxes with an overpressure of not more than 0.3 kgf / cm ² or vacuum systems, both in horizontal and vertical planes, can find application in chemical, radiochemical, pharmaceutical and other industries.

Known gate valve tight OST 95.431-76 (p. 5), adopted as an analogue.

The shutter gate tight includes the case flat rectangular. Inside the case there is a shutter (in the analogue - a shutter), resting on a guide rod (in the analogue - a running screw), gaskets (in the analogue - a sealing element) and a drive.

The disadvantages of this technical solution is the use of a guide rod seal assembly (in the analogue, a running screw) made in the form of an oil seal, as a result of which there is insufficient tightness during operation. And also the disadvantages are the difficulty of replacing the working gaskets and the lack of technological isolation of the penetration zone.

Closest to the technical nature of the claimed device is the "Gate device" according to copyright certificate No. 422139, class. F16k 3/00, 04.24.1972, adopted as a prototype.

The tight gate valve includes a housing with a bellows housing, and installed in the housing, a pressure plate (in the prototype, a movable flange), a gasket ring and a blanking ring (inserts in the prototype), sealing gaskets (in the prototype, an o-ring), magnets outer and inner magnets.

The disadvantage of this technical solution is the lack of external magnets and internal magnets between the rotary disk and the inserts and, as a result, the unilateral working position of the device (only in the horizontal plane), as well as the process of replacing the gasket associated with manual operations in a harmful environment.

The disadvantages are the long period of switching to the plug mode in connection with the manual operation, the periodic sticking of the gaskets at the interchangeable rings, due to the large contact area, due to the rectangular shape of the gaskets in the cross section and the lack of force that causes separation. The weak point of the design is the insecurity of the bellows housing, which requires special caution in technological operations.

The above disadvantages are absent in the proposed technical solution as a utility model.

The inventive utility model "Gate shutter tight" differs from the prototype in that the case is flat rectangular and contains additional external magnets and internal magnets installed around the perimeter of the blanking ring and spacer ring, as well as a hinged lid and a puller with a semi-automatic system containing a puller lever and puller pusher. The actuator rods are installed on the pressure plate, on which the rod bellows are located.

It also differs in that there is a shutter inside the housing, which is supported by a guide rod and a slide. The housing includes a telescopic pipe with a flange, consisting of two components connected through a spring, moving relative to each other. Sealing gaskets are made in the shape of a circle.

The technical task of the claimed utility model is the creation of a shutter gate valve, operable in both horizontal and vertical planes, with protection of the bellows assembly during technological operations, during operation of which it will be possible to tightly seal closed chamber cavities, boxes and speedy separation of cavities if necessary. It is also necessary to eliminate the sticking of the sealing gaskets and provide for their replacement with minimal consequences from the harmfulness of the working environment.

The technical solution to the problem is achieved in that the pipe is telescopic and protects the bellows of the housing. The use of additional external magnets and internal magnets installed around the perimeter of the blanking ring and the gasket ring makes it possible to operate the device in two planes, and also helps to detach the sealing gaskets from the base and pressure plate when removing the load from the pressure plate. The sealing gaskets are made in the shape of a circle, due to which, when removing the loads, they have a minimum contact area with the base and the pressure plate to which they are pressed. External magnets and internal magnets mounted on a trolley and curtain, are necessary for transmitting plane-parallel movement of the curtain through a sealed wall, for the speedy separation of the chamber cavities, if necessary.

Thanks to the external magnets and internal magnets installed around the perimeter of the plug ring and the pressure plate, the process of replacing the spacer ring and the plug ring is carried out in a short time and is reduced to simple operations, without consequences for the operating personnel from the harmful effects of the working environment.

The claimed utility model "Gate slide tight" meets the conditions of patentability.

The inventive utility model has novelty, since the totality of its essential features is unknown from the prior art, as shown by the applicant's patent research and the above analysis similar to the claimed technical solutions.

The utility model is industrially applicable, as it can be used in chemical, radiochemical, pharmaceutical and other industries.

And the whole set of essential features and each feature individually reproducible and do not contradict the achievement of the desired technical result.

To confirm the above, we present a description of the specific structural design of the claimed device and its operation.

The inventive utility model is illustrated by drawings, where in FIG. 1 shows a cross-sectional view of a slide gate valve; FIG. 2 - section AA (longitudinal section of the slide gate), in FIG. 3 is a section BB of FIG. 2 (cross section along the length of the slide gate), in FIG. 4 - remote element In FIG. 3 (view of a puller with external and internal magnets), FIG. 5 - remote element G of FIG. 3, illustrating the operation of a pressure plate for gasket sealing, FIG. 6 - remote element D of FIG. 4 illustrating the operation of a puller with a gasket ring (gasket removal), FIG. 7 - remote element D1 of FIG. 4, illustrating the operation of a puller with a gasket ring (gasket installation).

The hermetic shutter gate consists of a flat rectangular housing 1, which includes a shutter 2, a pressure plate 3, a trolley 4, a spring 5 connecting the two components of the telescopic nozzle 6, which serves to protect the bellows 7 of the housing 1. The hermetic shutter also contains a gasket ring 8 , the dummy ring 9, the external magnets 10 and the inner magnets 11 mounted on the trolley 2 and the shutter 4. The housing 1 additionally contains the outer magnets 12 and the internal magnets 13 installed around the perimeter of the spacer ring 8 and the stub ring 9, mag outer threads 14 and inner magnets 15 installed around the perimeter of the dummy ring 9 and pressure plate 3. The shutter 2 is supported by a guide rod 16 and a slide 17.

On the pressure plate 3 are installed the rods 18 of the drive plate 3 pressure, bellows 19 of the rod. The shutter 2 is driven by the drive 20 of the trolley 4. The body has three holes, the middle one has a through hole involved in the process, it has flanges 21 at the inlet and outlet, the outer holes have an auxiliary purpose for replacing the gasket ring 8 and the blanking ring 9 and have 22 hinged lids. An outer magnet 10 is fixed on the cart 4, and the counterpart — the inner magnet 11 is attached to the curtain 2. The outer magnets 10 and the inner magnets 11 mounted on the cart 4 and the shutter 2 are separated by a sealed non-magnetic wall (not shown in FIG.). Due to this, as well as the lack of gland connections, we obtain the tightness of the housing 1. Cart 4 has three rows of wheels in two planes and therefore the shutter can work normally in both vertical and horizontal planes. The shutter 2 is fixed on the rod 16 of the guide and moves along it and the slide 17. The shutter 2 has two holes of the same diameter, edged with closed outer magnets 12. Rings of two types are installed in the holes: a gasket ring 8 and a dummy ring 9. The design of the gasket ring 8 and the dummy ring 9 is almost the same, with the exception of the sealed partition at the dummy ring 9. The gasket ring 8 and the dummy ring 9 have at the ends, two rubber rings-gaskets 23 are sealing, which are made in the form of a circle in cross section.

The tight shutter gate also includes a puller 24 with a semi-automatic system comprising a lever 25 of the puller 24 and a pusher 26 of the puller 24.

The main material of the housing 1 is non-magnetic steel.

The inventive device operates as follows.

The shutter is built into the process chain using the flanges 21 of the middle hole of the housing 1.

Depending on the need, the middle hole can be hermetically sealed with a dummy ring 9 or can tightly connect the chamber cavities with a gasket ring 8. In the idle position, the plate 3 is pressed, under the influence of the rods 18 of the drive plate 3 is pressed, it rises, compressing the springs 5, and releases the gasket ring 8 or dummy ring 9 (see Fig. 5). In the working position, the reverse process takes place, and the springs 5 compress the gaskets, the sealing rings-gaskets 8 or the ring-plugs 9. In the form Г of FIG. 5 shows the operation of a plate 3 of compression compression ring gaskets of the sealing 23, the gasket ring 8 or the stub ring. In the inoperative position of the pressure plate 3, it is possible to move the shutter 2 from one end position to another (see FIG. 2). The shutter 2 moves thanks to the external magnets 10 and the internal magnets 11. When moving the shutter 2, the ring gasket 8 and the ring cap 9 are held in it by the action of the external magnets 12 and the internal magnets 13.

The purpose of the puller 24 is to remotely replace the gasket ring 8 and the blanking ring 9. Work with the puller 24 is as follows: with the lid 22 open, the hinged puller 24, which has the same mounting dimensions with the hinged lid 22, is installed on the flange of the lid 22 hinged, then the lever 25 of the puller 24 is put into working position, the spacer ring 8 or the blanking ring 9 is magnetically attracted to the puller 24 (see Fig. 6) and can be removed for disposal or repair. At the point of disposal, the lever 25 of the puller 24 is put into an inoperative position, the pusher 26 of the puller 24 becomes in the position shown in FIG. 7 and the gasket ring 8 or the dummy ring 9 enters the appropriate container for disposal. If necessary, the puller 24 may undergo a washing operation. Then, the puller 24 is transferred to the new ring-spacers 8 or ring-plugs 9, the lever 25 is transferred to the working position and the ring-spacer 8 or the ring-cap 9 is attached to the puller 24 under the influence of magnets (see Fig. 6). The puller is installed on the flange of the hinged lid, the lever is put into an inoperative position and the gasket ring 8 or the dummy ring 9, under the influence of magnets, is installed in the blind slot (see Fig. 7).

Thanks to the puller 24, direct contact of workers with contaminated spacer rings 8 or plug rings 9 is excluded.

When using the inventive shutter in production, the following technical advantages arise:

- tightness of the housing, which is achieved by the use of all external magnets and internal magnets;

- the use of telescopic nozzles eliminates damage to the bellows of the housing during operation, during technological operations;

- the operation of the device is possible both in horizontal and in vertical planes, which makes it possible to use the device in vertical technological chains between devices (for horizontal execution) and in horizontal chains between cameras or boxes (for vertical execution)

- when removing the load, the sealing gaskets have a minimum contact area with the base and the pressure plate to which the outer magnets and internal magnets are mounted, installed around the perimeter of the spacer ring 8 and the stub ring 9, set the spacer ring in a neutral position, tearing off the sealing gaskets from the base and pressure plate, which facilitates the replacement of the gasket ring and the stub ring.

- the process of replacing the gasket ring and the plug ring is carried out in a short time and is reduced to simple operations, without consequences for the operating personnel from the harmful effects of the working environment.
