Abstract
Avoid wearing and tearing and there is the borescope finder of sealing property, comprising mount pad, spring, O-ring seal, plug; Wherein: mount pad is cylindrical structure, be welded on cylinder type Thin-Wall Outer Casing; Plug front end is square boss, and both sides are with shirt rim, and boss center is female thread structure, and tail end is right cylinder; Mount pad is hollow cylinder, and in-line groove is opened in front end, and tail end opens circular hole, and Circularhole diameter is identical with plug tail end; Mount pad leading inside has ring groove, loads O-ring seal; At mount pad mounted inside spring.Advantage of the present utility model: structure is simple, sealing is better, and reliability is higher, and cost is lower, avoids the wearing and tearing between metal parts.In addition when vibration occurs plug in mount pad, can compress rubber seal thus realize effective sealing, overcoming the defect that overview device easily leaks gas, therefore practicality is better, is easy to apply, has larger practical value.
Description
Technical field
The utility model relates to borescope finder, particularly a kind ofly avoids wearing and tearing and has the borescope finder of sealing property.
Background technology
In modern gas turbines and test unit thereof, conveniently observe and keep in repair, usually needing on the critical piece of engine, to design borescope viewport, when gas turbine works, these viewports need to carry out shutoff with plug, cause loss in efficiency to avoid gas leak.Traditional borescope finder realizes compressing by round metal cross section Compress Spring, the characteristic line of this spring linearly, elastic modulus is larger, under the effect of vibration stress, larger friction force can be produced between spring self and plug and between plug and mount pad, cause the large area of plug to wear and tear, wear debris enters in casing runner by gapping of spring, forms potential safety hazard.In addition, this kind of structure observation device sealing property is poor, very easily causes gas leakage, thus causes loss in efficiency.In addition, if the metal fragment that wearing and tearing are formed enters in runner, also can have a strong impact on the trouble free service affecting gas turbine, therefore reliability is lower.
Utility model content
The purpose of this utility model be easily wear and tear to overcome between prior art borescope plug and borescope seat, problem that reliability is low, spy provides and a kind ofly avoids wearing and tearing and have the borescope finder of sealing property.
The utility model provides a kind ofly to be avoided wearing and tearing and has the borescope finder of sealing property, it is characterized in that: described avoid wearing and tearing and have the borescope finder of sealing property, comprises mount pad 2, spring 3, O-ring seal 4, plug 5;
Wherein: mount pad 2 is cylindrical structure, be welded on cylinder type Thin-Wall Outer Casing 1, air-flow flows out along casing 1 and mount pad 2;
Plug 5 front end is square boss, and both sides are with shirt rim, and boss center is female thread structure, and tail end is right cylinder; Mount pad 2 is hollow cylinder, and in-line groove is opened in front end, and tail end opens circular hole, and Circularhole diameter is identical with plug 5 tail end; Mount pad 2 leading inside has ring groove, loads O-ring seal 4; At mount pad 2 mounted inside spring 3.
Described spring 3 is the rubber spring that elastic modulus is less.
Advantage of the present utility model:
Described in the utility modelly avoid wearing and tearing and have the borescope finder of sealing property, structure is simple, and sealing is better, and reliability is higher, and cost is lower.When casing produces vibration, the regulating power of borescope finder self can slow down the impact of this vibration, thus avoids the wearing and tearing between metal parts.In addition when vibration occurs plug in mount pad, can compress rubber seal thus realize effective sealing, overcoming the defect that overview device easily leaks gas, therefore practicality is better, is easy to apply, has larger practical value.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is the borescope finder structural representation avoided wearing and tearing and have sealing property.
