Abstract

PNEUMATIC TRIGGER WITH SEPARATE BXOflAffe, Containing, enabling and disabling the inputs, direct output, power supply channel and distributor with input and output channels. The first control chamber and the second control chamber, in which the booster spring is installed, is connected with the fact that / in order to reduce hardware costs and expand the field of application, the trigger has an inverse output, and the first: distributor control chamber, which is made semilinear, connected to the first extreme output channel communicated in the initial position with the extreme input channel connected to the trigger input, the second extreme input wire connected to the trigger output and In the initial position, with the middle output channel communicated with the atmosphere, the middle input channel is connected to the inverse trigger output, the output channel is connected to the central inverse position, the output channel is connected to the power channel, and the control camera is connected to the initial position if tripping trigger input.

Description

The invention relates to discrete computing devices, namely, pneumatic triggers with separate inputs,

Known triggers with separate inputs containing on and off inputs, power channel and relay f 1 3.

A disadvantage of the known trigger is that the switching input in the initial position is connected to the output of the trigger. This reduces its speed when connecting a load with a significant amount and length of the transmission line of the switching signal.

Closest to the proposed ', in technical essence, it is a trigger containing an on and off input, a power channel, two distributors and an OR element [2], 20 The disadvantages of this trigger are a large number of pneumatic elements and the presence of only a direct exit.

The purpose of the invention is to reduce hardware costs and expand the scope of the trigger.

This goal is achieved by the fact that a pneumatic trigger with separate inputs, comprising turning on and off inputs, a direct output, a power channel and a distributor with input and output channels, a first control chamber and a second control chamber in which a support spring is installed, is provided with an inverse output, and the first control chamber of the distributor., which is made seven-linear, is connected to the first extreme output channel communicated in the initial position with the extreme, input channel connected to the including input at the trigger, the second extreme input channel is connected to the direct output of the trigger and to the middle input channel communicated in the initial position with the middle output channel communicated with the atmosphere, the other middle input channel is connected to the inverse trigger output communicated with the other average input-ed In the initial position, the output channel is connected to the power channel, and the second control camera is connected to the trigger trigger input.

The drawing shows a diagram of a pneumatic trigger with separate inputs.

The trigger contains 1 (S) and disconnecting 2 (R) inputs, direct 3 (Y) and inverse 4 (Ϋ) outputs. Seven-line distributor 5, co. holds input 6-9 and output 10-12 channels, as well as the first 13 and second 14 control cameras. The control chamber 13 is connected to the first output channel 10. The switching input 1 (S) is connected to the input channel 6. The input channel 9 is connected to the direct output 3 (Y) and the input channel 7. The output channel 11 is connected to the atmosphere. The input channel 8 is connected to the inverse output 4 of the trigger, and the output channel 12 is connected to the power channel 15. The camera 14 is connected to the trip input 2 (R) of the trigger. In the chamber 14, a spring 16 is installed.

The trigger is as follows.

In the initial position, the supply pressure through channels 12 and 8 of the distributor 5 passes to output 4 (Ϋ = 1), since channels 7 and 11 are connected to the atmosphere (Y = 0).

When a signal S - 1 is supplied to the switching input 1, the pressure passing through channels 6 and 10 switches the distributor 5, and through channels 12 35 to output 3 (V «1) _{, the} pressure from output Ϋ (and 11 is reset to the outputs are memorized (Y V = (S supply pressure 9 enters simultaneously through channels 8 atmosphere. Cu'g '1. 0) when the input signal 0 is removed).

When a signal is applied to shut-off input 2 (R "1), the distributor under the influence of pressure (R" 1) and spring force 16 returns to its original position regardless of (signal value $ "1 or -S" 0. Further work after the signal is received proceeds similarly when applying the enable signal S 1.

The effectiveness of the invention is determined by reducing the cost of its manufacture.
