SU17813A1 - Device to protect the mercury manometer from the effects of condensate and eliminate water hammer - Google Patents

Description

The invention relates to the adaptation of the ALE protection against direct contact of the condensate with mercury in a pressure gauge and the elimination of water hammer when the open knee of the pressure gauge is connected to the atmosphere in the case of measuring the absolute pressure within one atmosphere. In the proposed device, in order to separate the liquid from the vapor, one or several Angular tubes (provided with nozzles) are used to connect one end to the open end of the manometer, and the other through a three-way valve with a space in which pressure is measured.

In FIG. 1 and 2 depict a front and side view of a mercury manometer f with the proposed adaptation.

The open end of the pressure gauge 1 tube 2 is connected through the pipe 3 with the V-shaped pipe 3, which through pipe 3 is connected with the pipe 13 provided with a three-way valve 4, which is introduced into the space in which the pressure is to be measured. V-tube, which serves to separate the liquid from

A pair (of such tubes may be several connected to one another in succession) is provided with a cork stop valve 7 with a regulator of opening 14.

A three-way valve 4, placed between the nozzle 3 and the tube 13, due to the ratchet engagement 10, can always be rotated in only one direction, the open end of the pressure gauge is connected in series, first with the test space, then with the atmosphere and then the test space with the atmosphere.

For reading the pressure value behind the manometer tube, a scale 11 with divisions is placed, moved up or down with the help of a micrometer screw 12, in order to guide one of the levels of mercury by integer division.

The subject of the patent.

1. A device for protecting the mercury manometer from condensate and eliminating hydraulic shocks when the open knee of the manometer is connected to the atmosphere in the case of measuring the absolute pressure within one atmol Sphere, which is used to separate the liquid from the vapor from one or several V-shaped tubes 3 with cork stop valves with taps 7 and with an opening regulator 14 at one of them, which V-tubes are provided with connections 3, 3 for connecting the free end of the LofLHOro with the open end of the manometer with a tube 2, and another with a space in which pressure is measured .2. With the fixture described in paragraph 1, the use of a three-way crane 4 with ratchet engagement 10, which allows the crane to rotate in one direction, which is placed between the nozzle 3 and the space to be studied in relation to pressure, and first to connect the open end of the zanometer to the specified space, then with the atmosphere and then the investigated space with the atmosphere.
