Abstract
The utility model provides a single-point explosionproof DC sampling device, which comprises a shell and a cover, wherein the shell is in threaded connection with the cover; the shell has the same structure as that of a detector shell produced by MSA; the outer side of the shell is respectively connected with an air intake port, a cable gland head, a plug and air exhaust port; and the shell is internally provided with a vacuum electric pump, a vacuum switch, a control circuit board and a panel from bottom to top. The single-point explosionproof DC sampling device is simple in structure and convenient to operate, solves the problems of large size and poor reliability caused by dispersed connection of various components of the traditional sampling device, thereby being capable of achieving the purposes of reducing the manufacturing and mounting cost of the sampling device and improving the reliability and anti-explosion property of the sampling device.
Description
Technical field
The utility model relates to a kind of direct current sampling apparatus, especially relates to a kind of single-point explosion-proof type direct current sampling apparatus that sampling gas supplied gas detector to be detected detects and analyzes in negative pressure and explosion-proof environment.
Background technology
In the production run of oil, chemical industry, boats and ships, rock gas, Coal Chemical Industry and pharmacy etc., use sampling apparatus through regular meeting, extracting gases supplies detector to detect and analyzes from process units.Whether the gas that process units for confirmation produces in production run in controlled range, guarantee the quality of process units operate as normal and final finished simultaneously.Sampling apparatus in the past is through pipeline various former devices to be connected to one, is installed in the casing then.Thereby cause bulky and explosion-proof poor.If when needing multi-point sampling, because the mounting means of its mounting means and instrument is different fully, can cause the on-the-spot very difficulty of arranging and install, improved manufacturing and installation cost.
Summary of the invention
The purpose of the utility model is to solve sampling apparatus in the past causes the big and poor reliability of volume owing to each former device disperses to connect problem; Can reach manufacturing and the installation cost that reduces sampling apparatus thereby provide a kind of, and the single-point explosion-proof type direct current sampling apparatus that improves sampling apparatus reliability and explosion-proof.
In order to realize this purpose, the utility model is accomplished by following measure:
A kind of single-point explosion-proof type direct current sampling apparatus includes intake interface, explosion-proof casing, cable Ge Lan head, plug, dowel screw, vacuum switch, mounting screw, panel, nut, Explosion-proof cap, control circuit board, vacuum electric pump and exhaust port; The vacuum electric pump of telling and dowel screw be installed in the bottom of explosion-proof casing inner chamber respectively; Vacuum switch is welded on the reverse side of control circuit board; Control circuit board is fixed on the dowel screw through mounting screw then; Panel is fixed on the mounting screw through nut, and the internal thread of Explosion-proof cap and explosion-proof casing is tightly connected.
The further measure of the utility model is that the external form of explosion-proof casing and inner chamber are cylindrical, and the round boss of 4 inner bolt holes is arranged on the outer round surface, are connected with exhaust port with intake interface, cable Ge Lan head, plug respectively.
The further measure of the utility model is, the air intake opening of vacuum electric pump is connected in the inner chamber of explosion-proof casing with intake interface through pipeline, and the exhausr port of vacuum electric pump is connected in the inner chamber of explosion-proof casing with exhaust port through pipeline.
The further measure of the utility model is that explosion-proof casing is identical with the detector housing structure that MSA is produced with Explosion-proof cap.
The beneficial effect of the utility model is following:
One, the utility model reasonable in design, simple, easy for installation;
Two, the utility model can reach manufacturing and the installation cost that reduces sampling apparatus, improves sampling apparatus reliability and explosion-proof.
