Description

I

The invention relates to start-ups and can be used in those applications. equipment that requires a one-time supply of gas to a system with a high reliably long system: In the ready state in two modes; Starting (fsfsirovannom) and working. I From the main author. St. 3312О8, is known for its odious action, in which the inlet nozzle is sealed with a glass with a loosened ring and broken, which is broken off by a spring-loaded drummer, working from an electromagnetically operated drive, which has an open latch on the impactor, which is snapped by an electromagnetically operated drive, which is locked by a latching impactor, which is snapped by an electromagnetically operated drive, the measles are locked with a latching impactor, which has been snapped by an electromagnetically controlled drive, which has the latching hook of the spring drummer, which is cracked by an electromagnetically controlled drive, which is locked with a latching impactor, which is cracked by an electromagnetically controlled drive, which is locked with a latching hammer

However, the known valve, when turned on, has one operating position, and the gas goes to the system after operation. Constantly through one output, In systems that operate in two modes, for example, start-up, (with high costs), npxi output systems: "We are on mode and working (with lower costs, we have to set

one stop valve with remote control

by a magnetic-magnetic drive), which opens after the system has entered the operating mode.

The purpose of the invention is to expand the functional capabilities of the Start-up Valve, i.e., to obtain a dual-stage operation of the Valve from a single electromagnetic actuator.

This is achieved by the fact that the second valve is equipped with a seat, covered with a main valve, connected to the cortex of the electromagnetic actuator and opened under the action of this core simultaneously with the striker i of the impactor when the suture is fed to the electromagnetic actuator and closing when relieving stress. In addition, in order to reduce power, and, consequently., And the dimensions of electromagnetic water, measles is connected with the spool by means of a pusher supported on the spool at a point outside the saddle area and creating an overturning moment for the spool relative to the edge of the saddle.
