Abstract
The novel fitting seat plug of the one that the utility model provides, installing plug front end is cylindrical structural, diameter is less than the size at the switching boss place of fitting seat, tail end is ellipsoidal structure, with fitting seat elliptical aperture Spielpassung, tail end head is airflow design, the wall configuration rounding off of streamline shape and surrounding, and plug front end uses bolt presses sealing.The novel fitting seat plug of the one that the utility model provides, its advantage is: effectively can carry out shutoff to test fitting seat after a test, both reduce shutoff and lost the flow-disturbing of runner combustion gas, in turn ensure that sealing, reduced gas leakage.
Description
Technical field
This patent relates to gas turbine and testpieces thereof, is specifically related to a kind of novel fitting seat plug.
Background technique
In modern gas turbines and testing apparatus thereof, as general measure means, usually need at cavity section to temperature T, pressure P is measured, and this just needs in casing or the processing of wall place or adds work test fitting seat.For ensureing to measure accurately and reducing gas leakage, existing structure is the fitting seat of Fig. 1 form, it is characterized in that, fitting seat has through hole, and through-hole structure is divided into three sections, and through hole front end is thread pore structure 1, the shape of rear stomidium is oval 3, between front end and back end, be processed with circular switching boss 2, slotted eye major axis is less than tapped hole diameter, and switching boss 2 diameter dimension is greater than tapped hole 1 diameter.Usually after a test by screw thread blanking cover direct shutoff test fitting seat, the slotted eye of the inside is ignored.So simple shutoff can cause disturbance and the gas leakage of air-flow in runner, affects the performance of gas turbine.
Model utility content
The purpose of this utility model is for this test fitting seat, devises a kind of special shutoff plug, effectively can carry out shutoff to test fitting seat after a test, both reduce shutoff and lost the flow-disturbing of runner combustion gas, in turn ensure that sealing, reduced gas leakage.
Technical solutions of the utility model are: concrete structure is shown in Fig. 3, it is characterized by nose circle column construction, and diameter is less than the size at switching boss 2 place of fitting seat, have both been convenient to sealing, and have in turn ensure that installation.Tail end is ellipsoidal structure, and with fitting seat elliptical aperture 3 Spielpassung, tail end head is airflow design, and the wall configuration rounding off of streamline shape and surrounding, ensure that internal gas flow seamlessly transits herein.
Fig. 5 is shown in concrete installation, is tightened by screw plug above, and ensure that closely cooperating of plug and casing or wall, prevent gas leakage, the airflow design of plug tail end head is consistent with the streamline in runner again, the turbulence loss of reduction internal gas flow.

Embodiment
Embodiment
A special fitting seat shutoff plug, concrete structure is shown in Fig. 3, it is characterized by the cylindrical structural of plug 4 front end, and diameter is less than the size at switching boss 2 place of fitting seat, has both been convenient to sealing, and has in turn ensure that installation.Tail end is ellipsoidal structure, and with fitting seat elliptical aperture 3 Spielpassung, tail end head is airflow design, and the wall configuration rounding off of streamline shape and surrounding, ensure that internal gas flow seamlessly transits herein.
Fig. 5 is shown in concrete installation, is tightened by screw plug above, and ensure that closely cooperating of plug and casing or wall, prevent gas leakage, the airflow design of plug tail end head is consistent with the streamline in runner again, the turbulence loss of reduction internal gas flow.
