Common machine envelope is unable to reach requirement, and to generate uneven wear in the case where on-circular moves serious for ball face sealing,
Risk of leakage is larger, and the maintenance work of equipment is relatively difficult, so the stability and service life of butt joint have very high want
It asks.Existing sealing structure is unable to reach preferable effect for applying working condition, service life and maintenance requirement, whole to equipment
Using having an impact.
The content of the invention：
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, operation is steady
It is fixed, the whole contacted solar high temperature machine seal structure of normal operation that can be at high operating temperatures.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of entirety contacted solar high temperature machine seal structure, including housing, gland, hollow shaft and straight pipe, in housing
Be internally provided with hollow shaft, a gland is respectively equipped at the both ends of housing, housing is bolted to connection with gland, in shell
Between body and end cap be equipped with housing soft graphite pad, be welded on the end cap in left side one be connected with hollow shaft left end it is straight
Siphunculus.It is set in the hollow shaft of housing right part cavity there are two guide bearing, hollow shaft ensures rotation under the /V of guide bearing
Turn.Bearing spacer is equipped between two guide bearings.There is limit there are one being set in the hollow shaft on the left of the guide bearing of left side
The axis card of position guide bearing.It is equipped with static gasket, stationary seal ring, dynamic sealing successively in the housing hollow on the left of guide bearing
Ring, rotating seat, compensator, compensator supporting sleeve.Graphite packing is equipped between compensator supporting sleeve and compensator.In static seal
The left surface of ring is inlaid with sealing soft graphite pad.
Housing and gland form surface structure, and hollow shaft ensures rotation under the /V of guide bearing, and guide bearing is simultaneously
/V is carried out to stationary seal ring, sealing soft graphite pad ensures elevated-temperature seal, and the rotary packing ring being embedded at the top of compensator is being mended
It repays under the action of device with stationary seal ring gluing, sealing, to ensure the compensation performance of compensator, and inner chamber is completely cut off and is sealed, by mending
It repays supporting sleeve and carries out /V, and sealing is compressed to graphite packing.
The stationary seal ring is graphite annulus, and rotary packing ring is alloy hoop, using heat resistant and wear resistant alloy and high temperature resistant graphite
As main seal.
The compensator be FlexbleJoint, by the use of FlexbleJoint as compensate and seal means.
The beneficial effects of the utility model are：It is reasonable in design, it is stable, it is extremely low to requiring in terms of maintenance, it can be
Normal operation under the condition of high temperature.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
In figure：1 hollow shaft, 2 housings, 3 straight pipes, 4 glands, 5 compensators, 6 static gaskets, 7 stationary seal rings, 8 rotating rings
Seat, 9 rotary packing rings, 10 sealing soft graphite pads, 11 guide bearings, 12 compensator supporting sleeves, 13 bolts, 14 housing soft graphites
Pad, 15 bearing spacers, 16 graphite packings, 17 axis cards.
Specific embodiment：
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of entirety contacted solar high temperature machine seal structure, including housing (2), gland (4), hollow shaft
(1) and straight pipe (3), hollow shaft (1) is internally provided in housing (2), a gland is respectively equipped at the both ends of housing (2)

It pads (14), a straight pipe (3) being connected with hollow shaft (1) left end is welded on the end cap in left side.In housing (2) right part
It is set in the hollow shaft (1) of cavity there are two guide bearing (11), hollow shaft (1) ensures rotation under the /V of guide bearing (11)
Turn.Bearing spacer (15) is equipped between two guide bearings (11).In hollow shaft (1) on the left of left side guide bearing (11)
If there are one the axis cards (17) with limition orientation bearing (11).In housing (2) cavity on the left of guide bearing (11) successively
Equipped with static gasket (6), stationary seal ring (7), rotary packing ring (9), rotating seat (8), compensator (5), compensator supporting sleeve
(12).Graphite packing (16) is equipped between compensator supporting sleeve (12) and compensator (5).Left surface in stationary seal ring (7)
It is inlaid with sealing soft graphite pad (10).Housing (2) and gland (4) form surface structure, and hollow shaft (1) is in guide bearing (11)
/V under ensure rotation, guide bearing (11) at the same to stationary seal ring (7) carry out /V, sealing soft graphite pad (10) ensure
Elevated-temperature seal, the rotary packing ring (9) being embedded at the top of compensator (5) paste under the action of compensator (5) with stationary seal ring (7)
Sealing is closed, to ensure the compensation performance of compensator (5), and inner chamber is completely cut off and is sealed, /V is carried out by compensation supporting sleeve, and it is right
Graphite packing (16) is compressed sealing.
This structure is a kind of Novel machine seal structure by the use of FlexbleJoint (5) as compensatory device.For the prior art
Deficiency, using heat resistant and wear resistant alloy and high temperature resistant graphite as main seal, replaced using graphite packing (16) original
Rubber o-ring, and by the use of FlexbleJoint (5) as compensation and seal means, the seal means of alloy seal part and compensator (5)
