Abstract
The utility model relates to a steam turbine high pressure governing valve servomotor piston rod cooling device. The steam engine installation seat comprises a steam inlet cabinet and a servomotor installation seat connected to the steam inlet cabinet, wherein a piston rod is arranged on a lower shell of the servomotor installation seat, a cooling water channel is arranged in the lower shell of the servomotor installation seat, the piston rod is coated in the cooling water channel, and a water inlet pipe and a water outlet pipe which are respectively connected with two ends of the cooling water channel are arranged on the servomotor installation seat. The utility model discloses a cooling water course can be isolated the heat in the piston rod and open to continuously take away the heat through recirculated cooling water, prevent that the sealing washer on the piston rod from being heated for a long time and ageing with higher speed, prolong its life.
Description
Technical Field
The utility model relates to a steam turbine high pressure governing valve servomotor piston rod cooling device.
Background
Because the high-pressure throttle servomotor mounting seat of the steam turbine is tightly attached to the steam turbine steam inlet cabinet group, the heat of the steam turbine steam inlet cabinet group is conducted to the servomotor sealing ring through the servomotor mounting seat support, so that the local temperature of the servomotor mounting seat support is high (about 90-140 ℃), when the servomotor mounting seat support works in the high-temperature environment, the reliability and the service life of the servomotor sealing piece can be seriously influenced, and meanwhile, the safe operation of the steam turbine unit is also seriously threatened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a steam turbine high pressure governing valve servomotor piston rod cooling device to the problem that prior art exists.
The utility model discloses a concrete technical scheme as follows:
the utility model provides a steam turbine high pressure governing throttle servomotor piston rod cooling device, includes that steam enters the steam cabinet, connects in the servomotor mount pad of steam admission cabinet, the casing is provided with the piston rod under the servomotor mount pad, be provided with the cooling water course under the servomotor mount pad, the piston rod cladding is in the cooling water course, be provided with inlet tube and the outlet pipe of being connected respectively with cooling water course both ends on the servomotor mount pad.
The utility model discloses following beneficial effect has:
the utility model discloses a cooling water course can be isolated the heat in the piston rod and open to continuously take away the heat through recirculated cooling water, prevent that the sealing washer on the piston rod from being heated for a long time and ageing with higher speed, prolong its life.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the cooling device for the piston rod of the steam turbine high-pressure throttle servomotor comprises a steam inlet cabinet 1 and a servomotor mounting seat 2 connected to the steam inlet cabinet 1, wherein a piston rod 3 is arranged on a lower shell of the servomotor mounting seat 2, a cooling water channel 4 is arranged in the lower shell of the servomotor mounting seat 2, the piston rod 3 is coated in the cooling water channel 4, and a water inlet pipe 5 and a water outlet pipe 6 which are respectively connected with two ends of the cooling water channel 4 are arranged on the servomotor mounting seat 2.
The utility model discloses a concrete working process as follows:
the inlet tube 5 is discharged by outlet pipe 6 again to 4 water injections of cooling water course, and 4 inner loop of cooling water recooling water course flow, and steam advances when the heat transfer of 1 production of steam cabinet is to servomotor mount pad 2, and cooling water course 4 can be isolated the heat in piston rod 3 to continuously take away the heat through recirculated cooling water, prevent that the sealing washer on the piston rod 3 is heated for a long time and ageing with higher speed, prolong its life.
