SU416762A1 - DEVICE FOR ENSURING A GIVEN DILUTION IN BOXES AND CAMERAS - Google Patents

Description

one

The invention relates to equipment for security boxes and cameras, in particular for ventilation boxes and chambers.

We will inform you of the arrangement (devices for reducing the specified vacuum in the boxes and chambers, containing 1 two communicating vessels filled with liquid, one of which has a non-floating point.

However, the known devices do not provide automatic regulation of the amount of sucked air.

The aim of the invention is the automatic regulation of the vacuum rate and the amount of sucked air with this. so that the chamber or box does not have a thinning wall, and with it, cleaner air is introduced into the chamber.

To do this, in the device one of the capacitances is sealed and equipped, for example, with a pipe for communicating with the iolost box, the second tank is connected to the atmospheric valve and the non-valve is connected to the vertical The gate of the damper with the possibility of slippage, adjustable position of the body located on the stop bar.

Such an implementation of the device significantly reduces the amount of radioactive contamination by air activity.

The invention is in the form of drawings.

FIG. 1 Figure 1 shows the layout design of the cluster; in fig. 2-diagram installation of knots. 1) ka on the valve drive pin. A device for providing a setpoint of vacuum in the tanks and chambers contains a capacitance /, in the center

which has a pipe 2. dividing the entire space of e cosmos into two cavities: the rectal cavity.-1. connected to the atmosphere. annular cavity B, hermetic but relative to the atmosphere. Both cavities

connected by a hole 3 and filled with zhndkost, iprnmer. spun oil. There is a branch pipe 4 on the cover of the EMP. / 4, in which the throttle valve 5 is fixed, which extends the length of the throttle to zone B. located closer

to suction, and G. located closer to the camera. The zone G of the nozzle 4 is connected by the help of the tube 6 to the airtight container B. In the zone A, a non-floating 7 floats, which the lever 8 and the gear mechanism 9 are connected to

with the axis of the throttle valve 5. From the tube 2 goes the installation channel 10.

Float 7 has a through channel //. iri HOMorHjf of which he is capable of slipping the iasazhei on a vertical pin 12,

having a lower limiter 13 and upper

limiter 14, representing the coooii pins inserted into the holes 15, which are made in the pin 12 with an interval of 5 mm.

The device works as follows.

The nozzle 4 is molded in tiTcocy and the nolostyo G is connected to the chamber. Diluted c, created by suction, spreads to T; B, which results in a rise in the dorsal head D, and in the cavity L it hits, which causes the movement of the nonlavk 7 down.

Initially, the ion sink 7 slides along the vertical pin 12, until the norm until the difference ypoBisen in containers reaches 30 lmg (follower), the vacuum in the box is 24 mm water column, as the specific weight of the spindle oil is 0.8 g / s .and). Further application of the fluid level in the cavity L, which is a consequence of an increase in the extent of the thinning of the cavity of the box, will cause a permanent uninterrupted non-melting 7 with a vertical vanishing head 12. Increasing the damper valve 5, which reduces the cross section in the pipe 4, Serrated body, and the body will have a volume of 5. closing the damper in the MOAICHT, when the vacuum in the box is 40 mm.

Correct setting on

null is checked by HOMOHiH channel 10.
