Description
Technical field
The present invention is mainly concerned with the infrared hydrocarbon meter field, refers in particular to the packoff that a kind of infrared hydrocarbon meter is used.
Background technology
Along with continuous progress in science and technology, in order to reduce labour intensity, to increase work efficiency, more and more equipments all develops toward automaticity.Existing infrared hydrocarbon meter generally adopts automatic sample feeding mechanism that sample to be tested is operated, and under the work of driving arrangement, sample transfer bar is sent into sample to be tested in the body of heater through elevating movement after the adjustment of the position of tangential movement again.But it is not enough below existing structure exists: 1, in the seal assembly of sample transfer bar; O-ring seal often is installed in the top of lower seal bar and between upper seal support bottom and lower seal masthead portion; When seal bar decline instantly separates with upper seal support; The dust of cause flame tube generation in vitro can fall within O-ring seal and lower seal bar surface down, and the dust stratification of formation can have influence on sealing effectiveness and measuring accuracy after long-term the use; 2, " centering " of lower seal bar and bottom sealing socket can not be adjusted automatically, in turnover appearance process, misaligns the situation that influences sealing effectiveness easily.
Summary of the invention
The technical matters that the present invention will solve just is: to the technical matters that prior art exists, the present invention provide a kind of simple and compact for structure, with low cost, easy for installation, can improve the system test precision, prolong the seal assembly that is used for sampling mechanism of infrared hydrocarbon meter of seal durability.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of seal assembly that is used for sampling mechanism of infrared hydrocarbon meter; The lifter plate assembly that comprises upper seal support, lower seal bar, bottom sealing socket and be positioned at lower seal bar below; The top of said lower seal bar is sheathed in the upper seal support; The bottom of lower seal bar is sheathed in the bottom sealing socket, it is characterized in that: be provided with O-ring seal between the lateral surface of said lower seal bar and the inwall of upper seal support.
As further improvement of the present invention:
Said lifter plate assembly comprises up-down top board, up-down median septum and the hoistable platform of arranging successively from top to bottom; Said lower seal bar links to each other with the locking sleeve that is positioned at up-down top board bottom after passing bottom sealing socket, up-down top board, is provided with buffer spring between said up-down top board and the up-down median septum and between said up-down median septum and the hoistable platform.
Be equipped with two friction discs that are positioned opposite between said bottom sealing socket and the up-down top board and between said up-down top board and the locking sleeve.
The top of said lower seal bar extends to form stage portion along radial direction, and said O-ring seal is between the bottom of said stage portion to said bottom sealing socket and be installed in the mounting groove of offering on the lower seal bar lateral surface.
Compared with prior art, the invention has the advantages that:
1, the present invention is used for the seal assembly of sampling mechanism of infrared hydrocarbon meter; Simple and compact for structure, with low cost, easy for installation; O-ring seal is installed on the lateral surface of lower seal bar; Not only can prevent that dust stratification from can play good sealing effectiveness again simultaneously, can improve the stability and the system test precision of sealing property through the inside surface of O-ring seal wiping upper seal support.
2, the present invention is used for the seal assembly of sampling mechanism of infrared hydrocarbon meter; Be provided with buffer spring between up-down top board and the up-down median septum and between up-down median septum and the hoistable platform; Impulsive force when buffer spring not only can reduce to move can also further apply radial force to the lower seal bar, thus the crush seal circle; It better is adjacent to the upper seal support inwall, obtains the sealing effectiveness of the best.
3, the present invention is used for the seal assembly of sampling mechanism of infrared hydrocarbon meter; Be equipped with two friction discs that are positioned opposite between bottom sealing socket and the up-down top board and between up-down top board and the locking sleeve, can making through two friction discs to produce the less deviation motion between plate and the plate.When seal bar and O-ring seal were nested in the bottom sealing socket instantly, the automigration through friction disc can guarantee triangular right alignment, solves the automatic centering problem, makes O-ring seal compress unanimity, thereby improves its adaptive ability, reaches the optimal seal effect.

Embodiment
Below will combine Figure of description and specific embodiment that the present invention is explained further details.
Like Fig. 1, Fig. 2 and shown in Figure 3; The present invention is used for the seal assembly of sampling mechanism of infrared hydrocarbon meter; Comprise upper seal support 1, lower seal bar 2 and the lifter plate assembly that is positioned at lower seal bar 2 belows; The lifter plate assembly comprises up-down top board 3, up-down median septum 4 and the hoistable platform of arranging successively 5 from top to bottom; Hoistable platform 5 links to each other with the lifting assembly of sample feeding mechanism, and the sample transfer bar 9 of sample feeding mechanism passes upper seal support 1 back and is fixed on the lower seal bar 2 through sample presentation pole socket 10, and the top of lower seal bar 2 is sheathed in the upper seal support 1; The bottom of lower seal bar 2 is sheathed in the bottom sealing socket 11, is provided with more than one O-ring seal 6 between the inwall of the lateral surface of lower seal bar 2 and upper seal support 1.Offer the mounting groove more than on the lateral surface of lower seal bar 2, O-ring seal 6 is installed in the mounting groove.Like this, when sample transfer bar 9 moves up and down, can prevent that dust stratification from can play good sealing effectiveness again simultaneously, can improve the stability and the system test precision of sealing property through the inside surface of O-ring seal 6 wiping upper seal supports 1.Sample feeding mechanism comprises up-down driven unit 13 and translation driven unit 14; Up-down driven unit 13 drives hoistable platform 5 through up-down drive motor 131, up-down rotating band 132, elevating screw 133, riser guide 134, up-down driving wheel 135 and accomplishes elevating movement, and driven in translation assembly 14 drives whole translate stage 145 completion through pan drive motor 141, driven in translation wheel 142, driven in translation band 143, translation guide rail 144 and moves horizontally.
