Description

A kind of pneumatic logic unit

Technical field

The utility model belongs to pneumatic element, relates in particular to a kind of pneumatic logic unit.

Background technique

Pneumatic logic unit in existing air-channel system is connected and composed by pipeline by elements such as logic control valve, solenoid valve independently usually, the control of realization to pneumatic system, its defective is: integrated degree is low, the use element is many, take up room large, making and maintenance cost are high, use solenoid valve can't reach requirement of explosion proof.

Summary of the invention

The purpose of this utility model is the technological scheme that proposes a kind of pneumatic logic unit, realizes integratedly, satisfies requirement of explosion proof.

To achieve these goals, the technical solution of the utility model is: a kind of pneumatic logic unit comprises integrated gas circuit base, logic control valve; Be provided with gas circuit in described integrated gas circuit base, have at least three described logic control valves to be arranged on described integrated gas circuit base and by integrated gas circuit base and realize that gas circuit connects; Be provided with a work gas source interface on integrated gas circuit base.

Further, be provided with the control interface of andlogic control valve and φ 4 quick inserting joints that the work output interface is communicated with on described integrated gas circuit base.

Further, described logic control valve is Pneumatic two-position two-way valve or Pneumatic two-position three-way valve.

The beneficial effects of the utility model are: simultaneously integrated a plurality of logic control valves, realized the modular unit structure of pneumatic logic function, and the unified input of work source of the gas, simple in structure; Do not use electric elements, can satisfy requirement of explosion proof.

Below in conjunction with drawings and Examples, the utility model being done one describes in detail.

Description of drawings

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the utility model pneumatic schematic diagram.

Embodiment

As Fig. 1, a kind of pneumatic logic unit comprises integrated gas circuit base 1, logic control valve 2; Be provided with gas circuit in described integrated gas circuit base, have at least one described logic control valve to be arranged on described integrated gas circuit base and by integrated gas circuit base and realize that gas circuit connects; Be provided with a work gas source interface P0 on integrated gas circuit base.

In the present embodiment, be provided with altogether three logic control valves on integrated gas circuit base; Can carry out logical operation to four gas circuits simultaneously in pneumatic system.

In actual applications, can and customize supporting integrated gas circuit base according to the quantity of the function and structure customized logic control valve of pneumatic system; The general module that also can make seriation is used in pneumatic system.

Be provided with the control interface (P1, P4, P7 and P10) of andlogic control valve and φ 4 quick inserting joints 3 that work output interface (P3, P6, P9) is communicated with on described integrated gas circuit base, wherein interface P7 and P10 are attempted by on the control interface of a logic control valve; The work source of the gas input interface (P2, P5, P8) of logic control valve connects the work source of the gas by the gas circuit in integrated gas circuit base by work gas source interface P0.

Described logic control valve is Pneumatic two-position two-way valve or Pneumatic two-position three-way valve.

Logic control valve in the present embodiment adopts the normally-closed pneumatic two position three-way valve.

Set when requiring when the atmospheric pressure value on the control interface of a logic control valve reaches, this logic control valve begins action, and the work output interface of logic control valve is communicated with the input interface of working; Otherwise after the atmospheric pressure value on the control interface of logic control valve was cancelled, this logic control valve resetted, and the work output interface of logic control valve disconnects with the work input interface.

The utility model is integrated logic gas circuit and logic control valve, different logic control gas circuits is integrated in a modular unit, in order to control its integrated logic control valve, the modular unit that various gas circuit is integrated into be similar to circuit board is inner, reduced and outreached pipeline, compact structure has been realized the modular unit structure of pneumatic logic function.
