Abstract

The invention discloses a gas alternating system which comprises a valve body, a fixed core pressing ring and valve needles, wherein the valve body is arranged on an installing seat, a cavity is arranged in the valve body, the cavity penetrates through the valve body, one end of the cavity is provided with a valve seat, the side wall of the cavity is communicated with an air outlet, and the other end of the cavity is fixed with the fixed core pressing ring; the fixed core pressing ring is fixed with a pressing cap, the fixed core pressing ring and the pressing cap are hollow, and the hollow areas are communicated with an air inlet; and the valve needles are arranged in the hollow areas of the fixed core pressing ring and the pressing cap, one ends of the valve needles are provided with a pressure driving device, and the other ends of the valve needles are connected with the valve seat. According to the gas alternating system, through changing the pressures exerted on the valve needles, the valve needles drive a valve core to generate different displacements so as to control the flow rates of gas paths in the valve needles and the valve seat, thereby realizing the adjustment on ventilation volume according to actual conditions.

Description

A kind of gas alternate system
Technical field
The present invention relates to a kind of gas alternate system.
Background technique
For energy-conservation and minimizing noise, living space and working space are gradually to sealingization and heat insulationization trend development, but above-mentioned space is not easy to ventilation, and carbon dioxide content can increase gradually, is harmful to health.Therefore, need to take a breath to above-mentioned space, contaminated air in the space is discharged to the outside, fresh air outside is guided to inside.Existing air exchange system has just been set up the air communication channel of indoor and outdoor, and can not ventilation volume be regulated, and demands urgently improving.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of gas alternate system, by enforcement of the present invention, can regulate ventilation volume according to actual conditions.
For reaching this purpose, the present invention by the following technical solutions:
A kind of gas alternate system comprises:
Valve body is installed on the fitting seat, is provided with cavity in the described valve body, and this cavity runs through described valve body, and this cavity one end is provided with valve seat, and this cavity sidewalls is communicated with the air outlet, this cavity the other end with decide the core trim ring and fix;
Describedly decide the core trim ring, fix with pressure cap, and describedly decide the core trim ring and described pressure cap is hollow, this hollow region is communicated with suction port;
Needle is arranged on described hollow region of deciding core trim ring and described pressure cap, and described needle one end is equipped with pressure actuated device, and the other end is connected with described valve seat by spool.
Preferably, described air outlet is arranged on the valve body, or is arranged on the fitting seat.
Preferably, described suction port is arranged on the valve body, or is arranged on the fitting seat.
Based on disclosing of above technological scheme, the present invention possesses following beneficial effect:
The present invention imposes on the pressure of needle by change, makes needle band movable valve plug produce different displacements, and the gas circuit flow in control needle and the valve seat is realized regulating ventilation volume according to actual conditions.
