Abstract

The utility model provides a technical proposal of a rotary valve for liquid-vapor pipeline connection, which comprises a fixed sliding disc, wherein a sealing sliding ring, an oil supplying pipe and an oil returning pipe are arranged on the fixed sliding disc, a movable sliding disc is arranged on the upper surface which is corresponding to the fixed sliding disc, the oil supplying pipe and the oil returning pipe are arranged on the movable sliding disc, a tapered oblique surface and a groove are arranged on the periphery of the fixed sliding disc, and the periphery is sealed through three-stage sealing of asbestos cords with graphite powder, and a pressing spring and a spring support are sleeved on a central oil supplying pipe of the movable sliding disc for tightly pressing the fixed sliding disc and the movable sliding disc, thereby realizing the sliding seal. In the proposal, the movable sliding disc is connected with a rotated machine, the fixed sliding disc is connected with a heat conducting oil furnace or a vapor pipeline, two projected slide way loops are processed on a fixed disc for the first stage sealing and the second stage sealing, the tapered oblique surface whose bottom is small and mouth is big is processed on an external round edge, the same oblique surface is arranged on the corresponding position between the oblique surface and the movable sliding disc, and a loop groove is arranged on the oblique surface for installing the asbestos cords with graphite powder as the third stage sealing..

Description

A kind of liquid steam pipe road connects rotary valve

Technical field:

The utility model relates to a kind of valve, especially a kind of liquid steam pipe road connects rotary valve.

Background technique:

In the prior art, technique known is the heat-conducting oil heating pancake machine in usefulness, heat-conducting oil heating multi-position rubber vulcanizing machine, steam drum-type rubber vulcanizing machine, the machine of this scheme, all be that heat supply oil oven and pipeline are fixed, heated machine rotates, and this just requires the oil feed line can fuel feeding, can rotate again, the joint is difficult to reach do not rush down leaks and long-time the use, and this is the existing in prior technology deficiency.

Summary of the invention:

The purpose of this utility model is exactly at the existing in prior technology deficiency, and provides a kind of liquid steam pipe road to connect the technological scheme of rotary valve, this scheme is to adopt, and fixed disk is corresponding with sliding disc, realizes slipper seal, the use two-stage seals, and reaches the purpose of conveying and backflow conduction oil or steam.

This programme is realized by following technical measures: include and decide sliding plate, deciding has the sealing slipping ring on the sliding plate, with fuel supply line and return tube, sliding plate is arranged above, on the moving sliding plate fuel supply line and return tube are arranged, tapered slope and groove are arranged on the circumference of sliding plate, and have asbestos rope to add three grades of sealings of plumbago, and on the center fuel supply line of moving sliding plate, suit holddown spring and spring bracket, be used for compressing fixed disk and moving sliding plate, realize slipper seal.

The beneficial effect of this programme can be learnt according to the narration to such scheme, moving sliding plate in this scheme is connected with the machine that is rotated, deciding sliding plate is connected with heat-conducting oil furnace or steam line, on fixed disk, be processed with the slideway annulus of multiple tracks projection, do first secondary seal, be processed into osculum big tapered slope in the end on the outer circumferential edge, there is same inclined-plane the corresponding part of inclined-plane and moving sliding plate, one ring recess is arranged on the inclined-plane, be used for doing third level sealing by the asbestos rope of dress graphitiferous, can thoroughly eradicate the leakage of rushing down of flexible connection like this, and can reach the purpose of long-time use, also solve because of a conduction oil or the too high difficult problem that can not use rubber seal of vapor (steam) temperature, this shows, the utility model compared with prior art has substantial characteristics and progress, and the beneficial effect of its enforcement is conspicuous.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment.

Among the figure, 1 is liquid vapour supplying tube, and 2 is liquid vapour output tube, and 3 for to decide sliding plate, and 4 is spring bracket, 5 are moving sliding plate, and 6 is liquid vapour supplying tube, and 7 is liquid vapour output tube, and 8 is holddown spring, 9 is the one-level sliding ring, and 10 are the oil transportation chamber, and 11 is the secondary sliding ring, and 12 is asbestos graphite grazing band.

Embodiment:

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.

By accompanying drawing as can be seen, the liquid steam pipe road of this programme connects rotary valve, include and decide sliding plate (3) and liquid vapour supplying tube (1) on it and liquid vapour output tube (2), there are sliding plate (5) and liquid vapour supplying tube (6) and liquid vapour output tube (7) in the top corresponding with deciding sliding plate (3), and there are holddown spring (8) and spring bracket (4) to compress fixed, moving sliding plate, decide that described primary seal slip ring (9) and secondary seal slip ring (11) are arranged on the sliding plate (3), also have the third level sealing of asbestos graphite envelope band (12) in addition, between fixed, the moving sliding plate oil transportation, vapour chamber (10) are arranged.

Claims

1. a liquid steam pipe road connects rotary valve, include and decide sliding plate, deciding has the sealing slipping ring on the sliding plate, with fuel supply line and return tube, above corresponding with it sliding plate is arranged, on the moving sliding plate fuel supply line and return tube are arranged, deciding that tapered slope and groove are arranged on the circumference of sliding plate, and there is asbestos rope to add three grades of sealings of plumbago, on the center fuel supply line of moving sliding plate, suit holddown spring and spring bracket are used for compressing and decide sliding plate and moving sliding plate, realize slipper seal, it is characterized in that: the moving sliding plate in this scheme is connected with the machine that is rotated, decide sliding plate and be connected, on fixed disk, be processed with the slideway annulus of two road projectioies, do first secondary seal with heat-conducting oil furnace or steam line, be processed into osculum big tapered slope in the end on the outer circumferential edge, there is same inclined-plane the corresponding part of inclined-plane and moving sliding plate, and a ring recess is arranged on the inclined-plane, and the asbestos rope that is used for installing graphitiferous is done third level sealing.
