A kind of composite casing type sampler
Technical field
The utility model relates to a kind of composite casing type sampler, for the jet chimney of station boiler boiler and steam turbine, belongs to the steam sampling device technical field.
Background technology
In the boiler and steam turbine of generating plant, if contain too much impurity in steam, will cause superheater surface, steam turbine circulation part and jet chimney deposition salt crust, salt crust is deposited in heating surface pipe, and the heating surface pipe wall temperature is raise, and pipe burns out; Salt crust is deposited on steam turbine circulation part, and the steam turbine flow area is reduced, and blade roughness increases, and even changes the blade line style, and the steam turbine resistance is increased, and exerts oneself and Efficiency Decreasing; The valve place of salt dirt deposition jet chimney, may cause that the malfunctioning and valve of valve event leaks vapour, is the normal operation that guarantees boiler and steam turbine, must strict chemical supervision in boiler operatiopn.Sampler, as the main device of working medium sampling, to correct sampling and chemical supervision, guarantees the working medium quality, guarantees that boiler and Turbine Safety economical operation play an important role.
Tradition single tube seat sampler as shown in Figure 1, comprises that an end is located at the stopple coupon 4 in pipeline 1, and its other end overcoat has sampling base 2.There is following shortcoming in tradition single tube seat sampler: because sampler is cantilever design, the sample tap of stopple coupon 4 is difficult to flow to over against working medium, and the little wall of stopple coupon 4 general bore is thin, under high velocity air washes away, stopple coupon 4 easily shakes, the disengaging of may rupturing.Because the interior Temperature of Working of pipeline 1, airflow scouring intensity etc. are in dynamic change, can produce alterante stress to stopple coupon 4 simultaneously, can make its breaking releasing equally.Once the stopple coupon come off is broken, in steam turbine inlet pipeline 1, filter screen enters steam turbine high-pressure cylinder, will badly damaged blade, bring huge economic loss to power plant.Sampling base 2 is generally stainless steel, therefore poor with pipeline 1 weldability.
Summary of the invention
The purpose of this utility model is to provide a kind of safe and reliable, composite casing type sampler of facilitating processing and manufacturing and assembling maintenance.
In order to achieve the above object, the technical solution of the utility model is to provide a kind of composite casing type sampler, it is characterized in that, comprise the compound sleeve base of being located on pipeline or cylindrical shell, one end of stopple coupon is connected with the pipeline in the compound sleeve base, the other end is the enclosed construction that is positioned at pipeline or cylindrical shell, and the side that this end with enclosed construction flows to over against working medium is provided with at least one thief hole.
Preferably, described compound sleeve base comprises body base and composite bushing, and the body base is fixedly connected with described pipeline or cylindrical shell, and the body base is provided with composite bushing, composite bushing and described stopple coupon pipeline communication.
Preferably, described composite bushing comprises the outer tube of being located on the body base, and inside, outer tube upper end is located in the inner layer pipe lower end, and inner layer pipe is communicated with described stopple coupon.
Preferably, described body base inside coaxially is provided with sampling and strengthens pillar, and sampling is strengthened pillar inside and coaxially is provided with stopple coupon, and an end of this stopple coupon is fixedly connected with described outer tube, and the position of the relatively described thief hole of the other end is provided with breach.
Preferably, the perforate direction of described thief hole is vertical with the central shaft of described stopple coupon, and in the face of the airflow direction in pipeline or cylindrical shell.
Preferably, described enclosed construction is the cecum that described stopple coupon self forms.
Preferably, described enclosed construction comprises closure plate, is provided with the axis hole of wearing the end in described stopple coupon, and closure plate is located at the bottom in axis hole.
Preferably, the pipe thickness of described stopple coupon is not more than 1.5mm.
Preferably, the below of described stopple coupon is provided with fixed support block.
Inner layer pipe in the utility model, outer tube and body base are combined into the compound sleeve base of good airproof performance, and the scouring force that the recoil strength effectively stopple coupon born and steam bring is strengthened pillar by sampling and is passed on body base and cylindrical shell.Sampling reinforcement pillar can be protected and stopple coupon effectively, plays a supporting role, and while also having avoided operation, the possibility of sampler cantilever vibration, guarantee that sampler does not rupture, and can also avoid steam directly stopple coupon to be washed away.Stopple coupon can be chosen small-caliber thin-walled tube (wall thickness can be as thin as and be not more than 1.5mm) under the protection of sampling reinforcement pillar, is convenient to working medium is accurately sampled.In order to guarantee the steam sampling quality, General Requirements stopple coupon and inner layer pipe are all selected stainless steel material.Guarantee the weldability of different from the body base kinds of materials, outer tube can also be chosen the transition material between between bi-material, plays the material transitional function, can be widely used in body base and the pipeline of various materials.
The utility model has overcome the deficiencies in the prior art, by compound sleeve base and the sampling of sealing, strengthens pillar, has improved the rigidity of sampler, has strengthened the safety and reliability of sampler operational process, simple in structure, manufactures easy to assemblyly, is convenient to safeguard.
