    2, Installation in accordance with claim 1, 1, and TL, which means that the valve of the non-return valve is installed in the gateway body by means of a branch pipe inserted into the section of the pipeline that connects the 5-way gateway to the pump and is connected to it.
    3. Installation pop.1, different from the fact that the valve
    The invention relates to the field of cleaning equipment from impurities and can advantageously be used for cleaning steam turbine condensers of power plants.
    The aim of the invention is to simplify the design and increase the reliability of the installation in operation.
    The FIG shows an apparatus for the ball cleaning of heat exchangers, a general view; figure 2 - mounting the check valve on the wall of the gateway; on fig.Z - mounting the check valve at the mouth of the input line to the gateway; Fig. 4 shows the installation in the position of storing the balls in the gateway.
    The unit for ball cleaning of heat exchangers includes a cooling water circuit consisting of cooling water inlet t, heat exchanger 2 with inlet chamber 3, heat exchanger tube 4 of the exhaust chamber 5 and cooling water outlet nozzle 6, in which sieve 7 is rotatably installed, and also a pressure sensor 8 for measuring the flow resistance of the sieve. Parallel to the heat exchanger 2 between the inlet 1 and outlet 6 by the cooling water nozzles, there is a gateway 9 for collecting and storing cleaning sponge rubber balls 10, consisting of a cylindrical body 11, which contains a funnel-shaped sieve 12. 1 The joint 9 is connected to the inlet cooling water outlet 6 line 13 with pump 14 and shut-off valve 15 entering the upper

    check valve is installed on the wall of the gateway housing.,
    4. Installation according to claim 2, which means that the nozzle has a rectangular flange with hinges for mounting the flap at one end, and the other end of the nozzle is made with V-shaped slots in the longitudinal direction.
    gateway zone. A non-return valve 16 is installed inside the gateway 9 in the zone of accession of the inlet line 13 to it. The bottom end of the sieve 12
    through a pipe 17 is connected to a valve 18 connected by an outlet line 19, provided with a stop valve 20, to an inlet pipe 1 of cooling water and having an open pipe 21.
    When mounting the check valve 16 directly on the inner wall of the gateway body 11 (Fig. 2), the valve axis 22 passing through
    fold on the upper edge of the valve, installed with the possibility of rotation in two hinges 23 and 24, mounted on the sides of the wall of the housing 11. In this case, the check valve 16
    can be closed by a spring force (not shown). The closing density of the check valve 16 must be such as to exclude the possibility of transferring the sponge rubber balls 10 from the sieve 12 back to the input line 13. If necessary, the check valve 16 may be
    made slightly curved in accordance with the radius of the cylindrical wall of the housing T1.
    The return valve 16 can be fixed at the mouth of the inlet line to the gateway (FIG. 3), while the pipe 25 with the flange 26 protruding outwards at its end inside the casing is inserted into the mouth of the inlet line 13 so that the flange 26 fits tightly to the wall of the housing 11 gateway 9. On. A flush 26 inside the case, with a rectangular outer contour corresponding to the size of the non-return valve 16, is pivotally hung in the respective hinges 27 and 28 on the upper edge of the flange. The check valve 16.
    In order to improve fixation, the pipe 2 may contain longitudinally extending and V-shaped slots 29 that extend along the inlet line 13, and with the same outer diameter of the nozzle 25 and the inner diameter of the inlet line 13, the nozzle 25 is clamped elastically . In this way, ease of installation is achieved, which, however, ensures sufficient fixation.
    The unit for ball cleaning of heat exchangers operates as follows.
    The valves 15 and 20 are opened, the valve 18 is moved to the position shown in Fig. 1, and the pump 14 is turned on. The water flow 10 balls from the gateway 9 are transported through the output line 19 to the cooling water inlet 1 and enter the heat exchanger 2, Pass through the pipes 4 heat exchangers, cleaning balls | The balls are caught by the sieve 7 and sent to the suction port of the pump 14 and further to the lock 9. The check valve 16 in this case does not prevent the balls from entering the lock.
    Figure 4 shows the principle of operation of the check valve 16 in the trap phase

    and holding the sponge rubber balls 10 in a sieve 12. To do this, the shutter 18 is turned 90, causing the passage from the sieve 12 to the output line 19 for the sponge rubber balls 10 to be blocked. Thereafter, the pump 14 is disconnected, which is formed due to the pressure difference between the inlet nozzle 1 and the outlet nozzle 6 for the cooling water, a bypass flow. flows in the direction of arrow 30 through the outlet line 19 and the lower port 21 of the shutter 18 to the inlet line 13 (the outlet 6 for the coolant is excluded).
    Thus, it suffices to move the valve 18 and turn off the pump 14 (which can be easily automated) without other valves actuating. You only need to, for example, open the gateway 9 by removing the cover 31 to remove the balls 10 from it sponge rubber, it is advisable to additionally close the valves 15 and 20, which can be done both manually and with the help of a servomotor.
    Thus, the installation of a check valve in the recirculation line for cleaning bodies creates a functionally more reliable and practically damage-free structure, which significantly reduces the performance of process operations in installations for the ball cleaning of heat exchangers.
