Abstract
The utility model discloses a kind of structure for water intake ball valve maintenance sealing machine locking, using lock nut, locking level and locking wedge block integrated structure, drive locking level that locking voussoir is made to enter maintenance sealing and between upstream flange, guarantee to exit when maintenance seals maloperation by spin locking nut.And at investment end and end setting limiting device is exited, and bite and drainage are avoided the occurrence of, it is compact-sized, it is highly-safe, it can be widely applied on hydroturbine water intake ball valve.
Description
Technical field
The utility model relates to a kind of hydroturbine water intake ball valves to overhaul sealing machine locking structure:
Background technique
Hydroturbine water intake ball valve maintenance is sealingly disposed in ball valve upstream side, only when unit maintenance when side is put into.It overhauls close
After envelope investment, blocking flow action is played, it is ensured that in the case that upstream pressure steel pipe does not drain, service personnel is to unit ball valve
Back part carries out repair and maintenance.Maintenance sealing in order to prevent is opened by mistake to open and is caused damages to service personnel, thus maintenance sealing,
Locking device is set between valve body and upstream flange, and when guaranteeing unit maintenance, maintenance sealing has been at investment state, guarantees power station
And maintenance personal's safety.
Country's water intake ball valve maintenance sealing locking at present is mostly screw rod investment.After maintenance sealing investment, rotary screw makes
Bar investment is put into, blocks maintenance sealing ring from rear portion.This structure, screw rod put into position and exit position and do not limit, Zhi Nengren
For setting investment and exit position, it is excessive and exit difficulty often to there is investment, or exit excessive, sealing ring is scurried out and leaked
The phenomenon that water.
Summary of the invention
The purpose of the utility model is to provide a kind of hydroturbine water intake ball valves to overhaul sealing machine locking structure, locking device
Be mounted on valve body, can be prevented after maintenance sealing investment it is accidentally affected open maintenance sealing, while there is investment and exit limit
Position effect, reduces the bite and drainage of locking device, guarantees power station and maintenance personal's safety.
The purpose of this utility model is achieved through the following technical solutions: locking voussoir (1) connect with locking level (2),
Locking level (2) is put together on lock nut (6) by nut (7), and thrust block (10) puts together on locking voussoir by bolt (3)
(1) on, limit plate (8) is mounted between guide sleeve (5) and lock nut (6), and spin locking nut (6) drives locking voussoir
(1) it is moved up and down in guide sleeve (5), realizes that maintenance sealing (12) is locked between valve body (4) and upstream flange (11), rubber
Circle (9) guarantees that the pressure water in valve body (4) will not leak out.
The utility model advantage is:
1, easy to operate, compact-sized, structure is reliable；
2, there is investment and exit double limitation, reduce leak or bite risk；
3, highly-safe, it can be widely applied on hydroturbine water intake ball valve.
Detailed description of the invention
Fig. 1 is that the utility model structure puts into status diagram
Fig. 2 is that the utility model structure exits status diagram
Specific embodiment
As shown in Figure 1, the utility model is that a kind of hydroturbine water intake ball valve overhauls sealing machine locking structure, voussoir is locked
1 connect with locking level 2, locking level 2 is put together in lock nut 6 by nut 7, and thrust block 10 puts together on locking by bolt 3
On voussoir 1, limit plate 8 is mounted between guide sleeve 5 and lock nut 6, and spin locking nut 6 drives locking voussoir 1 being oriented to
It is moved up and down in set 5, realizes that maintenance sealing 12 is locked between valve body 4 and upstream flange 11, rubber ring 9 guarantees water-tight.
Although above-mentioned be described in conjunction with basic principles and main features of the attached drawing to the utility model.The skill of the industry
Art personnel are all to use equivalent substitution or equivalent transformation it should be appreciated that above-described embodiment does not limit the utility model in any form
The technical solution that obtains of mode, all fall within the protection scope of the utility model.
