Abstract
The utility model relates to an improved structure of a Roots blower safety valve, which is characterized in that a pressure relief valve and a pressure meter are arranged on a valve body of a check valve, so the function of the pressure relief valve, the function of the pressure meter and the function of the check valve are integrated into one body, the functions are not reduced, the installation space is reduced, so the installation is convenient, in addition, the manufacture cost is also reduced, and the Roots blower safety valve is more suitable for being used for a Roots blower with a compact structure and a small size.
Description
Technical field
Model utility is the improvement to the roots blower safety valve structure, relates in particular to a kind of combination safety valve of compact structure.
Background technique
For guaranteeing the roots blower safe operation, in blower fan outlet three safety installationss are installed usually, i.e. pressure gauge, Decompression valves, safety check.Because blower fan manufacturing and pressure gauge, Decompression valves, the safety check manufacturing adheres to different manufacturers separately, then by making the combination of roots blower producer, so be for a long time by the buying safety valve, then three safety installationss are installed on two pipeline sections in turn, be provided with pressure gauge and Decompression valves near the fan outlet tube section, its outer safety check that connects again.This structure has not obtained changing since roots blower is built substantially.Three safety installationss divide two sections to be installed in series, and not only make volume become big, and have increased manufacture cost, and for compact structure, the roots blower that volume is little is undesirable.Above-mentioned deficiency still has is worth improved place.
The model utility content
The model utility purpose is to overcome above-mentioned the deficiencies in the prior art, and a kind of installation province that takes up room is provided, and cost is low, the roots blower safety valve that blower fan is easy for installation.
The model utility purpose realizes that main the improvement is three kinds of safety installationss that are installed in respectively on two segment pipes former, stack mounting on check valve body, thereby overcome the deficiencies in the prior art, realize the model utility purpose.Specifically, model utility roots blower safety valve comprises Decompression valves, pressure gauge, safety check, it is characterized in that described Decompression valves, pressure gauge are installed on the check valve body.
Model utility roots blower safety valve, with respect to prior art, owing to adopt Decompression valves, pressure gauge be arranged at the check valve body composite structure, Decompression valves, pressure gauge, three kinds of functional safety devices of safety check are integrated in one, do not reduce function, but reduced installing space, make to install and become convenient, and saved manufacture cost, and being more suitable in compact structure, the roots blower that volume is little uses.
Optimize specific embodiment below in conjunction with one; model utility essence is further understood in exemplary illustration and help; but embodiment's detail only is for model utility is described; do not represent model utility design whole technological schemes down; therefore should not be construed as the total technological scheme of model utility is limited; some are In the view of the technician; the unsubstantiality that does not depart from the model utility design increases and/or change; for example change or replace, all truely use novel protected scope so that technical characteristics with same or similar technique effect is simple.
Description of drawings
Fig. 1 is model utility roots blower combination safety valve structure schematic representation.
Embodiment
Embodiment: referring to Fig. 1, model utility roots blower safety valve on the pipeline of check valve body 4, check valve plate 3 inboards, is respectively arranged with the Decompression valves 1, the pressure gauge 2 that are communicated with gas channel, constitutes the combination brake switch and proporting structure.
To those skilled in the art; under this patent design and specific embodiment enlightenment; some distortion that can directly derive or associate from this patent disclosure and general knowledge; those of ordinary skills will recognize also can adopt additive method; or the substituting of known technology commonly used in the prior art; and the equivalence of feature changes or modification; mutual various combination between feature; for example Decompression valves 1; pressure gauge 2 position changes; or the like unsubstantiality change, can be employed equally, can both realize this patent representation function and effect; launch for example no longer one by one to describe in detail, all belong to this patent protection domain.
Claims (2)
1. the roots blower safety valve comprises Decompression valves, pressure gauge, safety check, it is characterized in that described Decompression valves, pressure gauge are installed on the check valve body.
