Abstract
The utility model belongs to the technical field of gas calorific value instruments and particularly relates to a gas sampling device for being matched with a gas calorific value instrument. The gas sampling device is composed of a gas sampling pipe penetrating into a gas pipeline, a flange ball valve connected with the sampling pipe and a sampling head connected with the flange ball valve. The gas sampling device is characterized in that the sampling head is composed of a straight pipe section, a bend connected with the straight pipe section and a horn opening connected with the bend. A connecting ring sleeve in sliding connection with the straight pipe section is arranged on a joint of the gas pipeline and the straight pipe section of the gas sampling pipe. The horn opening and the gas flowing direction are opposite in directions. The gas sampling device has the advantages that full pressure can be taken, pressure loss is small, moisture and sundries on an inner wall of the pipeline are prevented from entering a sampling pipeline, and the gas sampling device is simple and convenient to install and high in adaptability.
Description
Technical field:
The utility model belongs to the fuel gas caloric value determination apparatus technical field, especially relates to the matched gas sampling device of a kind of fuel gas caloric value determination apparatus.
Background technology:
The gas sampling apparatus structure that traditional supporting fuel gas caloric value determination apparatus is used is very simple, is exactly that one section white steel pipe one end connects sampling line, and the other end is inserted in the gas piping, even be not inserted in the gas piping, and only equal with gas piping.This gas sampling device sampling poor, the coal gas appearance two atmosphere pressure losses of taking-up is big, and impure, moisture content is more, is unfavorable for the normal operation of fuel gas caloric value determination apparatus.
Summary of the invention:
It is a kind of simple in structure, convenient that the purpose of the utility model is to provide, and adaptability is strong, and it is effective to take a sample, and can get total head, and the few matched gas sampling device of fuel gas caloric value determination apparatus of the pressure loss.
The purpose of the utility model realizes through following technical proposals:
The matched gas sampling device of the fuel gas caloric value determination apparatus of the utility model; By the gas sampling pipe that penetrates in the gas piping, gas sampling pipe flange connecting ball valve therewith, the sampling head that connects of flanged ball valve is formed therewith; It is characterized in that described sampling head is by straight length; The elbow that connects of straight length therewith, the hydraucone that connects of elbow is formed therewith, is provided with the connection ring set that is connected with straight length at described gas piping with gas sampling pipe straight length junction.
Described hydraucone and flow of gas direction oppositely are provided with.
The principle of work of the utility model:
When coal gas flows, can receive the retardance and the perturbation action of gas piping inwall in gas piping, and then the variation that produces whirlpool district and velocity distribution; Resistance to flow is increased, and the pressure loss increases, and with respect to the gas piping inwall; The centre of gas piping is to receive the minimum place of resistance; The pressure loss is also minimum, and the gas piping inwall is moisture more with impurity, and the centre that therefore sample tap of ST is located at gas piping is the most rational.Front end at stopple coupon installs hydraucone additional, and bell-mouthed direction and flow of gas in the opposite direction cooked to guarantee that the pressure that ST is got is total head like this, reduces the loss of pressure.
The straight length of the sampling head of the utility model can put mobile at abutment ring; Caliber according to the gas piping of reality; Sampling brains front end is deep into the centre of gas piping, confirm good position after, make the direction of the hydraucone of ST front end facing to flow of gas; The inwall of abutment ring is welded on the stopple coupon straight length, and outer wall is welded on the gas piping.Can guarantee to adapt to the caliber of various gas pipings like this, stopple coupon can be installed in the middle of the pipeline all the time.The other end of flanged ball valve can weld the sampling line of different tube diameters according to the actual conditions at scene.
The advantage of the utility model:
The utility model is simple in structure, convenient, and adaptability is strong, can get total head, and the pressure loss is few; Also avoided simultaneously moisture content, the impurity of inner-walls of duct are taken in the sampling line, appearance is effective.
Description of drawings
Fig. 1 is the structural representation of the utility model
Embodiment:
Embodiment below in conjunction with description of drawings the utility model.
As shown in Figure 1: the matched gas sampling device of the fuel gas caloric value determination apparatus of the utility model; By the gas sampling pipe 1 that penetrates in the gas piping 7; Gas sampling pipe flange connecting ball valve 2 therewith; The sampling head of flanged ball valve 2 connections is formed therewith, it is characterized in that described sampling head by straight length 4, therewith the elbow 5 of straight length 4 connections; 6 compositions of hydraucone of elbow 5 connections are provided with the connection ring set 3 that is connected with straight length at described gas piping 7 with gas sampling pipe straight length 4 junctions therewith.Accurately behind the sample position of adjustment sampling head in gas piping, outer wall that connects ring set 3 and gas piping 7 are welded, and connect the inwall and 4 welding of stopple coupon straight length of ring set 3, form the web member of sealing, in order to guarantee to get total head, the pressure loss is few; Also avoided simultaneously moisture content, the impurity of inner-walls of duct are taken in the sampling line.
The described hydraucone 6 of the utility model oppositely is provided with the flow of gas direction, and the haircut among the figure is the flow of gas direction.
Claims (2)
1. matched gas sampling device of fuel gas caloric value determination apparatus; By the gas sampling pipe that penetrates in the gas piping, stopple coupon flange connecting ball valve therewith, the sampling head that connects of flanged ball valve is formed therewith; It is characterized in that described sampling head is by straight length; The elbow that connects of straight length therewith, the hydraucone that connects of elbow is formed therewith, is provided with in described gas piping and gas sampling pipe straight length junction with straight length is slidingly connected to be connected ring set.
