Abstract

The invention relates to mechanical engineering, in particular, to devices for draining fluid from high pressure systems, for example, terminal seals of turbo compressors, and it allows to increase reliability under conditions of variable overpressure. The fluid diverter comprises a housing (K) 1 with an outlet channel 14, a cover 2 with an inlet channel 3. In C 1, a cavity 10 is made in which a spring-loaded valve 11c is located with sensitive and actuating elements 12 and 13. The float 5 is connected by a lever link 6 with shut-off body 7, closing the axial channel 9. With increasing pressure in the lid 2, pressure is transmitted from the bottom through channel 9 to the shut-off body 7, unloading it through the channels 15 and 16. The float 5 floats, the actuating element 13 under the action of the spring 19 moves to the left opening the discharge 14. Channel 2 z.p.f. 2 Il. Shg-4 41 About the joint venture

The invention relates to mechanical engineering, namely, to devices for cooling water from high-pressure systems, such as end seals of turbo-compressors.

The goal of the invention is to increase the reliability of the conditions of variable overpressure and ensure dynamic stability.

FIG. 1 schematically shows a liquid outlet; in fig. 2 - spring loaded valve.

The liquid outlet includes a housing 1 with a lid 2. The lid 2 is provided with an inlet channel 3 and a nozzle 4 is installed for exhaust gas. In the lid 2 there is a float 5. connected by a lever link b with a shut-off member 7 interacting with the seat 8 having an axial channel 9. The housing 1 has a cavity 10. in which is placed a spring-loaded valve 11c with sensing and actuating elements 12 and 13, respectively can be rigidly interconnected to form a differential piston. The outlet channel 14 formed in the housing 1 is blocked by the actuating element 13. An additional channel 15 is provided in front of the sensing element 12 in the housing 1. A longitudinal channel 1G is formed in the valve 11. In the sensing element 12 is installed throttling means, made in the form of a check valve 17 and the nozzle 13. A spring 19 is installed between the valve 11 and the sensing element 12.

The device works as follows.

If there is no liquid in the lid 2 and dzlgni in the system, the float 5 is in the lower position, the locking member 7 closes the axial channel 9. The spring-loaded valve 11 under the action of the spring 19 is in the left position, the vip-iron channel 14 is open. When liquid enters the cover 2, the latter passes through the channel 15 into the cavity 17, through the jet 18. The longitudinal channel 16 passes into the cavity 10 in front of the actuating element 13. As the float 5 ascends, the liquid from the cover 2 through the channel 9, the cavity 10 and the discharge channel 14 merges from the otvodchika. As the pressure in the lid increases, the lift force of the float 5 becomes insufficient to raise the closure member 7. However, the increased pressure through the channel 15 is transmitted to the sensing element 12,. breaking the force of the spring 19, will move the executive s / h-e1 ;; 13, which will block the graduation ceremony. K. In this part

Fluid flows through the channels 15 and 16 into the axial cable 9. The pressure in which increases and will be affected by the locking member 7 from below. The float 5 will run out and the liquid through the channel 9 will begin to drain.

since the valve 11 is at this moment unloaded, the spring 19 will move the element 13 into and open the exhaust channel 14. When the fluid level in the cover 2 decreases, the float 5 will lower, the axial channel 9 will be blocked by the locking member 7, the spring-loaded valve 11 will operate and the actuating element 13 will block the outlet 14.
