SU960562A1 - High temperature media pressure pickup - Google Patents

Description

   one .

The invention relates to instrument making, in particular, to devices for measuring pressure in temperature and temperature environments.

Pressure sensors of viscous media, such as polymer melts Cl, are known.

The disadvantages include the inconvenience of exploitation.

The closest in technical essence and the achieved result to the pre-, Q lagable is a sensor containing a separating unit with a threaded fitting sleeve, inside of which is placed a catller with a liquid closed by a separating membrane, and the measurement is a pebble 2.

In this sensor, the separation membrane is rigidly connected to the sleeve (housing), and therefore, during installation and dosing, the instruments must be rotated 20 together with the sleeve, which is extremely inconvenient during operation.

The purpose of the invention is to simplify installation during operation and verification.

This goal is achieved by the fact that, in the pressure sensor, the dispensing unit is provided with a split sleeve, which is located inside the threaded sleeve and is rigidly connected to the inserted fit g sensor with a fitting attached to the separation membrane, and the free end of the cut sleeve is filled in the shape of a truncated the cone, which is above the cylindrical part and the threaded sleeve is mounted on the landing sleeve with the possibility of axial movement in the direction of the measuring unit and is provided in the lower part with an annular ledge with the inside with KtsiycoM imprinted on its inner surface.

FIG. 1 shows the sensor, the common Vic; in fig. 2 - section AA I.

Claims (1)

The sensor consists of measuring 1 and separating 2 nodes connected by capillary 3. Separating node 2 consists of separating membrane 4, welded to sleeve 5, rigidly connected to the end of the cylindrical part of the split guillot 6, Second end of the slotted bend 6, Cone-shaped cBo6otb remains. The threaded sleeve 7 is freely located on the mullet 5 and can rotate around the axis and rise to the height of the cylindrical part of the split sleeve 6. The height of the pilinaric part of the split I sleeve 6 is selected and the condition that the threaded sleeve can be completely unscrewed This is the ledge B, the device works as follows. When stacked, the sleeve 5 is installed in the seat of the process equipment (pipeline, extruder) and is pressed against the lower threaded sleeve 7 by .-. Wrapping the latter along the thread. Since the threaded sleeve 7 is installed freely in the separator assembly, when it rotates, the device remains stationary, . The removal of the device is described as follows. The threaded sleeve 7 is extruded from the process equipment. In order to remove the separation membrane 4, it is necessary to pull the threaded sleeve 7, which, clinging to the ledge C behind the shoulder B of the split 6, carries the separation membrane assembly 4, the free end of the split sleeve 6 is tapered, the larger diameter of the cone is larger the diameter of the cone of the thread sleeve 7, and the diameter r1 of the cylindrical part of the cutting sleeve 6 is smaller than the diameter of the cone. When assembling dividing knot 2, it is necessary to thread a loose, conical shaped slot 7 into the threaded sleeve 7 with a large force. When disassembling dividing knot 2 it is necessary to move the threaded sleeve 7 along the q / rndrich part of the sleeve 6, and squeeze the free end Impact threaded sleeve 7. Experimental samples of this prior have been created. They have passed operational tests in chemical fiber processing machines and in Maumtiax for reprocessing synthetic rubber, where they showed themselves on the positive side, Technical o-eksmomichesky effect of the invention - reduction of the time spent on pover15u.i setting tool. The invention The pressure sensor of high-temperature environments, containing a separating unit with a threaded mounting sleeve, inside which is placed a capillary liquid, closed by a separating membrane, and a measuring unit, which is also distinguished by the fact that, with the aim of installation, it is up to In it, the separating unit is provided with a split sleeve, which is located inside the reekbine sleeve and is rigidly connected to the landing sleeve inserted into the sensor, attached to the separating membrane, the free end of the cut The hot sleeve is made in the shape of a truncated cone protruding above the cylindrical part, and the rebar sleeve is mounted on the mounting sleeve with the possibility of axial movement in the direction of the measuring unit and provided in the lower part with an annular ledge with an internal KOHVnnK.
