Description

Automatic automatic flow control of batch-type float type for compressed air pipelines, launcher and under pressure, in which rubber diaphragms are used as valves, are known.

A special feature of the front end of the condensate drain is that, in order to simplify the design of the operating differential pressure of the valve actuator, the following diaphragms are used, blocking the drainage opening of the dl the discharge of condensate and canal. in the housing cover, associated with the volume of condensate, and the upper diaphragm, which is connected to the noiLiBBKOM, is controlled by blocking the opening in the housing cover, which serves to release air from the cavity between the valve diaphragms.

In addition, a replaceable nozzle was used in the lid of the coddepsatoothodik housing, with the aim of gradually filling the cavity between the valve diaphragms with air and adjusting the flow rate of condensate.

A steam trap allows large volumes of water to be discharged and ensures high operational reliability.

The drawing shows schematically an incision of the air trap 1Ps with the assembled membrane ch.chapan.

The steam trap consists of a housing /, upper valve 2, lower crane 3, a water gauge stack 4 and sunk into the body of the copper tube, 5. Through the holes in KpbrnJKe 2, air and condensate are supplied, and from the holes in the lower bracket 3, 1 strip of low pressure air is blown out. At the bottom of the wedge there is a flange 6 and diaphragm 7, and at the top there is a diaphragm 8, which is connected to step 10 by means of ball 1P1p.9. scab to the upper corner of the upper part of the enclosure. Attachment to the reflector //. In the bottom cover of the housing HOMenieH Жк.ча 12.

Co1-gensatasvodchk 11k works as follows.

Condensate with air const} Ch1aet to the air distributor through the answer in the cradle 2 11 falls on the reflector 7 /. Through the radial holes to the bottom cover 3, the condensate falls under the diaphragm 7 and fills the chamber space. As a result, the float / O raises the diaphragm (V, which opens from; a small cross section connected to the atmosphere). Differential pressure diaphragm 7 under pressure of condensate iodine is lowered, and the coideisate is released into the sewer.

When buoyancy is lost, the float is lowered and the channel is closed to release air into the atmosphere.

Water continues to flow into the sewage system until the slow flow through the nozzle 12 compressed air fills the cavity between the diaphragms and the lower diaphragm does not block the channel for discharge. The release time of the co-ordinate is controlled by a funny jet 12.
