Abstract
The invention relates to an improved superheated steam sampler with high security and stability. The improved superheated steam sampler comprises a sampling head, a tube union, a close board, a container or a pipeline and is characterized in that a joint seat is sleeved at the root part of the sampling head; the joint seat is connected with the root part of the sampling head by a threaded matching mode and is firmly connected with the container or the pipeline through welding; and the joint seat and the container or the pipeline are made of the same material.
Description
(1) technical field
The present invention relates to the boiler structure technical field, is specially a kind of modified superheated steam sampler.
(2) background technology
The operation of under high temperature, high pressure superheated steam environment, working of the sampling head of superheated steam sampler and sampling line, guaranteeing that metallic element is not transferred in the steam goes, its sampling head and pipeline all adopt austenitic steel, otherwise can cause the superheated vapor quality untrue, its data that record are wrong and can't effectively control the quality of superheated vapor.Its sampler of existing superheated steam sampler is an austenitic steel, its collection case or pipeline are carbon steel or the firm material of alloy, the firm material of carbon steel or alloy is non-austenitic steel, sampler adopts welding method to be connected with collection case or pipeline, because the welding of (non-austenitic steel) just of austenitic steel and carbon steel or alloy is to belong to different steel grade welding, after its welding, the linear expansion coefficient of the transfer of element and two kinds of steel is factor not or the like, cause the mass defect of welding joint weld seam inside easily, as pore, cracking etc., and then cause fault, even split off by high velocity vapor stream, rush at steam turbine, cause the generation of the major accident of ruining machine, so its security is low, stability is low.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of modified superheated steam sampler, its safe, good stability.
Its technical scheme is such: it comprises sampling head, pipe adapter, shrouding, collection case or pipeline, it is characterized in that: plinth is set in described sampling head root, described plinth is connected with described sampling head root threaded engagement, described plinth and described collection case or pipeline welding are fastenedly connected, and the material of described plinth is identical with the material of described collection case or pipeline.
It is further characterized in that: described sampling head, plinth connection of thread connect away from the screw thread place seal welding of described collection case or pipeline one end, the junction of described plinth and described collection case or pipeline has the groove of working in coordination, be welded to connect described groove of working in coordination, described sampling head top and described pipe adapter are welded to connect, and described sampling head bottom is welded to connect with described shrouding.
In the said structure of the present invention, its plinth is set in described sampling head root, described plinth is connected with described sampling head root threaded engagement, described plinth and described collection case or pipeline welding are fastenedly connected, the material of described plinth is identical with the material of described collection case or pipeline, because described sampling head is welded to connect described collection case or pipeline by thread set in the plinth of its root, and the material of described plinth is identical with the material of described collection case or pipeline, it belongs to steel grade and welds, so it can not produce the unfavorable factor of different steel grade welding etc., so it is safe, good stability.
(4) description of drawings
Fig. 1 is a front view synoptic diagram of the present invention.
(5) embodiment
See Fig. 1, the present invention includes sampling head 1, pipe adapter 2, shrouding 3, collection case or pipeline 4, plinth 5 is set in sampling head 1 root, plinth 5 is connected with sampling head 1 root threaded engagement, plinth 5 is fastenedly connected with collection case or pipeline 4 welding, and the material of plinth 5 is identical with the material of collection case or pipeline 4.Sampling head 1, plinth 2 connection of thread connect away from the screw thread place seal welding of collection case or pipeline 4 one ends, plinth 5 has the groove of working in coordination with the junction of collection case or pipeline 4, be welded to connect the groove of working in coordination, sampling head 1 top and pipe adapter 2 are welded to connect, and sampling head 1 bottom and shrouding 3 are welded to connect.6 is thief hole, and 7,8,9,10 is weld seam.
Claims (1)
1. modified superheated steam sampler, it comprises sampling head, pipe adapter, shrouding, collection case or pipeline; Plinth is set in described sampling head root, and described plinth is connected with described sampling head root threaded engagement; It is characterized in that: described plinth and described collection case or pipeline welding are fastenedly connected, and the material of described plinth is identical with the material of described collection case or pipeline; Described sampling head, plinth connection of thread connect away from the screw thread place seal welding of described collection case or pipeline one end; The junction of described plinth and described collection case or pipeline has the groove of working in coordination, and is welded to connect described groove of working in coordination; Described sampling head top and described pipe adapter are welded to connect, and described sampling head bottom is welded to connect with described shrouding.
