Description
Technical field
This utility model relates to a kind of novel pitch LVDT support.
Background technology
Pitch LVDT support act as the displacement of valve switch and is sent to LVDT displacement transducer, LVDT synchronize valve displacement amount to be changed into the signal of telecommunication, as the negative-feedback signal of servo amplifier；Unit operation repeatedly occurring, valve event is abnormal, upon examination it is found that fixed support bolt looseness between LVDT and valve.Concrete reason be existing LVDT support universal-joint when valve quick acting, deformation of timbering, it is impossible to effectively transmit moment.And universal joint post gap by long-term use becomes big；All there are two LVDT displacement transducers above each valve, require vertical when LVDT sensor is installed, be not allow for deviation, and the bolt hole spacing of support is certain, causes regulation inconvenience, it is impossible to be adjusted to optimum position.
Utility model content
This utility model aims to solve the problem that the problems referred to above, it is provided that a kind of novel pitch LVDT support, and it is compared and only uses the support of connecting rod to have more preferable stability and structural strength, and modulability is high, can effectively transmit moment；Its technical scheme used is as follows: a kind of novel pitch LVDT support, it is characterised in that including:
LVDT displacement transducer；
Rotation section；
Supporting part；
Movable axis；
Cover；
Slip cap；With
Fixed cover；
The bottom of described support is rotatably connected to rotation section, rotation section is also rotationally connected with supporting part simultaneously, it is connected with movable axis under supporting part, described movable axis is threaded onto the cover being fixed on slip cap and movable axis inserts in slip cap, the bottom of movable axis is connected with lower fastener, being inserted with the slip cap of limited slip in the described fixed cover being fixed on steam turbine, described movable axis can conditional slide up and down in slip cap.
On the basis of technique scheme, described movable axis being also connected with fastener, upper fastener is connected with slip cap outer wall elasticity by upper spring, and lower fastener is connected with the inwall elasticity of slip cap by lower spring.
On the basis of technique scheme, the end of described slip cap has two projections, and described projection can fix slide anteroposterior in the groove on jacket wall.
On the basis of technique scheme, described movable axis can be silica gel material.
On the basis of technique scheme, described supporting part is cylinder and a diameter of 10mm.
This utility model has the advantage that to compare and only uses the support of connecting rod to have more preferable stability and structural strength, and modulability is high, can effectively transmit moment.

Specific embodiment
With embodiment this utility model is further expalined explanation below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, a kind of novel pitch LVDT support, it is characterised in that including:
LVDT displacement transducer 1；
Rotation section 2；
Supporting part 3；
Movable axis 6；
Cover 7；
Slip cap 5；With
Fixed cover 4；
The bottom of described support is rotatably connected to rotation section 2, rotation section 2 is also rotationally connected with supporting part 3 simultaneously, supporting part is connected with movable axis 63 times, described movable axis 6 is threaded onto the cover 7 being fixed on slip cap 5 and movable axis 6 inserts in slip cap 5, the bottom of movable axis 6 is connected with lower fastener 9, being inserted with the slip cap 5 of limited slip in the described fixed cover 4 being fixed on steam turbine, described movable axis 6 can conditional slide up and down in slip cap 5.
On the basis of technique scheme, described movable axis 6 being also connected with fastener 8, upper fastener 8 is connected with slip cap 5 outer wall elasticity by upper spring 10, and lower fastener 8 is connected with the inwall elasticity of slip cap 5 by lower spring 10 '.
On the basis of technique scheme, the end of described slip cap 5 has two projections 51, slide anteroposterior in the groove 41 on described protruding 51 energy fixed cover 4 walls.
On the basis of technique scheme, described movable axis 6 can be silica gel material.
On the basis of technique scheme, described supporting part 3 is cylinder and a diameter of 10mm.
A kind of novel pitch LVDT support of this utility model is transformed for original support, eliminates connecting bolt and the universal joint of centre, absorbs moment to improve stability and the reliability of support by providing limited sliding to be used for.
When steam-turbine unit valve rapid movement, carry out in allowing the projection 51 groove 41 on fixed cover 4 of slip cap 5 end limited before and after slide, allow movable axis 6 to be perpendicular to slip cap 5 simultaneously and carry out limited sliding up and down, and rotation section 2 is also rotary relative to supporting part 3 and frame bottom.Movable axis 6 and is respectively arranged with a spring in slip cap 5 in cover 7, elastic the coupling together of outer wall of the upper fastener 8 being fixed on movable axis 6 with slip cap 5, another lower spring 10 ' will be fixed in the lower fastener 9 of movable axis 6 bottom and elastic the coupling together of inwall of slip cap 4 by one upper spring 10.So when the power of upper and lower displacement occur in support or movable axis 6, movable axis 6 can slide up and down in slip cap 5, and by the pulling force that the outside elastic force of upper spring 10 and lower spring 10 ' are inside during slide downward, otherwise the power being subject to during upward sliding is the most contrary.So movable axis 6 can be provided the technical scheme of limited slip.
In order to enable higher raising elastic performance of the present utility model, movable axis 6 can use the resilient silica gel material of tool, simultaneously in order to strengthen intensity of the present utility model, is thickeied to 20mm by traditional 10mm by supporting part 3.
Being illustrated this utility model the most by way of example, but this utility model is not limited to above-mentioned specific embodiment, all any changes done based on this utility model or modification belong to the scope that this utility model is claimed.
