FIELD: gas industry; production and transportation of gas.

The invention relates to devices for automation of technological processes and can be used in the gas industry objects in the extraction and transport of gas. Known borehole wellhead metering device reagent (A.S. No. 1080022, MKI G 01 F 13/00, containing the capacity for reagent and gas valve with balancing tube. The metering device allows you to submit reagent, for example methanol, in the piping to prevent condensation. However, this device has a major drawback - when the pressure in the pipe is increased reagent consumption. The closest technical solution is a device to prevent condensation (A.S. No. 775625, MKI G 01 F 15/02). The device has two cameras, placed coaxially relative to each other. In one, the inner chamber, has a valve site. This camera through hole connected to the pipeline, and the outer chamber is filled with reagent and has a pulse tube connected to the valve. This device eliminates the condensation in the pulse tube. However, the presence of the valve block in communication with the pipeline does not allow to use this device to connect, for example, bezrassadnyj pressure sensors or differential sensors, as the valve site in ASIC distortion. In addition, it is possible condensation in the chamber between the valve hub and the hole for the gas. The aim of the invention is the extension of functionality, namely the ability to connect the pressure sensors and differential pressure sensors high precision to the gas without condensation, to simplify the design and increase reliability. This goal is achieved by the fact that the device prevent hydrate formation containing liquid reagent chamber in a sealed vessel, is connected with the pulse line and livealone tube and located in the camera tube, the lower end connected to the pipe in the lower end of the tube is placed fluoropolymer fitting hole which reduces the gas exchange between the camera and the pipeline, while the chamber is filled with liquid reagent to a level not exceeding the upper end of the tube. The analysis found in the patent search, the information and catalog materials to prevent condensation on the funds of the regional universal scientific library of Saratov, allows us to conclude that the proposed device is not known from the prior art, that is new. In addition, the proposed device is not clear from review of the dummy sources, ie has an inventive step. The design of the proposed device to prevent condensation caused by operational practices, namely, that the known devices are complicated in design and do not provide protection against condensation in the pulse tubes connecting the differential pressure sensors or other bezyshodnaya sensors with the pipeline. The implementation of the proposed design of the camera in a sealed vessel, and in the lower end of the tube - PTFE fitting allows for filling the chamber with a reagent with a high partial pressure, to obtain the number of reagent vapor in the tube 5-10 times more content of moisture vapour in the gas, resulting in a pair of moisture connected with the reagent and the dew point is reduced, thus preventing hydrate formation in a pulsed sensor tube and hydrate formation in the socket. Therefore, the proposed device has industrial utility. The invention is illustrated in the drawing. The device prevent condensation contains the camera 1, is designed as a sealed vessel filled with liquid reagent and the tube 2 connected to the pipe 3 by the lower end of which contains fluoropolymer fitting 4 hole, pulse line 5 connecting the camera 1 with the sensor 6 and livealone line in the form of a vent is La 7, connected to the lower part of the chamber 1. The device prevent hydrate formation is as follows. The gas from the pipe 3 passes through the hole in the nozzle 4 and the tube 2 enters the space of the chamber 1, is not filled with liquid reagent. It should be stated that the chamber 1 is filled with a reagent with a high partial pressure of, for example, methanol, to a level not exceeding the upper end of the tube 2. Under this condition, the amount of methanol vapor in the internal cavity of the camera 1 in 5-10 times the content of moisture vapour in the gas. The result is a pair of moisture in Gaza connect with methanol and the dew point is reduced, which eliminates the possibility of condensation in the chamber 1 and in the pulse tube 5 connecting the camera 1 with the sensor 6. A small hole in the nozzle 4 reduces the gas exchange between the camera 1 and the pipe 3, which provides reliable operation for a long time, and performing fitting 4 PTFE and its location on the end of the tube 2 at a minimum distance from pipeline 3 helps to prevent hydrate formation in the space between the nozzle 4 and the pipe 3 and the socket 4 due to the hydrophobic properties of PTFE. It should be emphasized that at the present time in the oil and gas industry there is the problem of ensuring reliable operation of the pressure sensors and differential, installed on the pipelines due to the clogging of the hydrates channels (tubes)that connect these sensors to the pipeline in the winter. The use of this device allows a simple and reliable way to solve the problem and ensure the normal operation of, for example, information systems. The device prevent hydrate formation containing liquid reagent chamber in a sealed vessel, is connected with the pulse line and livealone tube, and located in the camera tube, the lower end connected to the pipeline, characterized in that the lower end of the tube is placed fluoropolymer fitting hole which reduces the gas exchange between the camera and the pipeline, while the chamber is filled with liquid reagent to a level not exceeding the upper end of the tube.
