Abstract
The utility model relates to a temperature, pressure and flow velocity integrated sampling device based a gas flue. The device comprises a pressure sampling tube, a temperature sampling tube and a pitot tube. Main technical features of the device are that the pressure sampling tube, the temperature sampling tube and the pitot tube are sleeved in a protection tube and are vertically welded on a flue connecting piece, another ends of the pressure sampling tube, the temperature sampling tube, the pitot tube and the protection tube are mutually welded together, a middle part of another side of the flue connecting piece is installed with a pressure difference transmitter which is connected with the pitot tube to collect the flow velocity of flue gas, and the flue connecting piece next to the pressure difference transmitter is installed with a pressure transmitter which is connected with the pressure sampling tube to collect the pressure of the flue gas. The device has the advantages of reasonable design, simple structure, easy production, strong practicability, safety and convenience, fast installation, trouble saving and the like, the work efficiency is improved, and the convenience of using and carrying is increased.
Description
Technical field
The utility model belongs to the environmental protection equipment field, especially a kind of temperature based on gas stack, pressure, flow velocity one sampling apparatus.
Background technology
In gas-monitoring, need to monitor the temperature in the measurement gas flue, pressure and flow velocity.At present, temperature, pressure and flow velocity in the measurement gas flue is to be inserted into by independently steel pipe and pitot tube to obtain corresponding data in the chimney, the frame mode of this dispersion requires the flange of chimney larger, or need chimney to leave three mounting flanges, install and safeguard all inconveniences.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reasonable in design, simple in structure, installation and the temperature based on gas stack, pressure, flow velocity one sampling apparatus easy to use are provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of temperature based on gas stack; pressure; flow velocity one sampling apparatus; comprise the force samples pipe; temperature sampling pipe and pitot tube; described force samples pipe; the temperature sampling pipe; pitot tube is sleeved in the protection tube and is vertically welded on the flue web member; the force samples pipe; the temperature sampling pipe; pitot tube and the protection tube other end weld together each other; at the middle part of flue web member opposite side pressure difference transmitter is installed and is connected for the flow velocity that gathers flue gas with pitot tube, pressure unit is installed and is connected for the pressure that gathers flue gas with the force samples pipe at the other flue web member of pressure difference transmitter.
And described force samples pipe is connected with pressure unit by the passage that turns round in flue web member inside.
Advantage of the present utility model and good effect are:
1, the utility model is sleeved on temperature sampling pipe, force samples pipe and pitot tube group in the protection tube and welds together with the flue web member and form one-piece construction, has guaranteed the stability of sampling apparatus.
2, the utility model only needs the integrally-built sampling pipe of formations is inserted in the chimney, and the mounting flange of reserving with chimney can form good fit, the realization sealing effectiveness.
3, the utility model is reasonable in design, has simple in structure, the characteristics such as make that easy, practical, safe ready, installation are saved trouble fast, has improved work efficiency, increases the convenience of using and carrying.
Description of drawings
Fig. 1 is structural drawing of the present utility model (cut-open view);
Fig. 2 is that the A-A of Fig. 1 is to cut-open view.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of temperature based on gas stack, pressure, flow velocity one sampling apparatus as shown in Figures 1 and 2, comprise protection tube 4, force samples pipe 5, temperature sampling pipe 6, pitot tube 7, flue web member 3, pressure unit 2 and pressure difference transmitter 1.Force samples pipe, temperature sampling pipe, pitot tube are sleeved in the protection tube; one end of force samples pipe, temperature sampling pipe, flow velocity sampling pipe and protection tube is vertically welded on the flue web member and with the flue web member and forms integrative-structure; the other end of force samples pipe, temperature sampling pipe, flow velocity sampling pipe and protection tube welds together each other, and the length of above-mentioned various pipes and caliber are according to equipment erecting stage Location of requirement.Pressure difference transmitter is packed in the middle part of flue web member opposite side, and be connected with pitot tube for the flow velocity that gathers flue gas, pressure unit is installed on the flue web member on pressure difference transmitter next door and with the force samples pipe and is connected for the pressure that gathers flue gas.Because the pressure difference transmitter physical dimension is larger, therefore, the force samples pipe is realized being connected with the pressure unit interface by the passage that turns round in flue web member inside.
This temperature, pressure, flow velocity one sampling apparatus are coated with fluorine to the sampling apparatus black box and process after welding, with strengthen Corrosion Protection and can prevent bonding, thereby guaranteed serviceable life and the test accuracy of sampling apparatus.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model comprises and is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to equally the scope of the utility model protection.
