Abstract
Anti-active and anti-negative respiration valve apparatus composed of valve body as main body, which is characterized in that the valve body cavity is disposed with a vertical baffle, between the baffle and valve body is a gapping place, the baffle separates the valve body into two cavities, opening one hole above one cavity and connecting a intake tube, opening one hole on side face of another cavity connecting discharge tube, the upper opening of valve body cavity connecting a liquid intake opening, middle and bottom of the valve body side face respectively arranged with a pressure gauges and a liquor drainage valve with a liquid-level meter pm the valve body side face. The utility model is provided with advantage as follows: admission pressure and pressure at expulsion can be adjusted according to needs by regulating liquid height with high accuracy; two or more than two containers with identical pressure can share one; employing liquid seal apparatus, capable of avoiding jamming and leakage. The apparatus can be widely used in flexible air accumulator for storing gas and steel tank, processing promotional value.
Description
Technical field
The utility model relates to a kind of anti-PNPB control valve unit, refers in particular to breather valve device and adopts two-way fluid-tight principle.
Background technique
At present, check valve apparatus and mechanical type breather valve device are widely used in containers such as the flexible gas holder of stored-gas and steel tank.Check valve apparatus can only reduce pressure, and when the gas pressure in the container was lower than external air pressure, check valve apparatus was ineffective, causes seal container sunken; The mechanical type breather valve device is to utilize the difference of the container inner pressure of the gravity of valve and stored-gas to protect the safety of container, but the mechanical type breather valve device exists phenomenons such as jam and leakage in actual application.Above-mentioned valve is because the defective of self exists potential safety hazard in application process.
Summary of the invention
The purpose of this utility model provides the anti-PNPB control valve unit of a kind of easy to operate, good airproof performance, high safety.
A kind of anti-PNPB control valve unit is to be that main body constitutes by valve body, it is characterized in that described body cavity is provided with a vertical baffle plate, the gap is left in baffle plate and body cavity bottom, baffle plate is divided into two cavitys with valve body, above a cavity, open a hole, and connect a suction tude, open a hole on top, another one cavity side, connecting bleeder pipe, the top opening of body cavity, connect a liquid entering hole, the middle part of valve body side and bottom are respectively equipped with a pressure gauge and a liquid discharging valve, are provided with a level meter on side of valve body.
The utility model has following advantage: suction pressure and exhaust pressure can be regulated the height of liquid as required and be realized control, validity height; The container of two or more uniform pressure can be shared one; Adopt liquid seal device, can avoid jam and leakage; Simple in structure, processing and easy for installation.This device can be widely used in containers such as the flexible gas holder, steel tank of stored-gas, has promotional value.
Description of drawings
Fig. 1 the utility model structural representation;
Among the figure: 1 valve body, 2 baffle plates, 3 suction tude, 4 bleeder pipes, 5 liquid entering holes, 6 pressure gauges, 7 liquid discharging valves, 8 level meters.
Embodiment
A kind of anti-PNPB control valve unit is to be made of for main body valve body 1, it is characterized in that described valve body 1 inner chamber is provided with a vertical baffle plate 2, baffle plate 2 leaves the gap with valve body 1 intracavity bottom, baffle plate 2 is divided into two cavitys with valve body 1, above a cavity, open a hole, and connect a suction tude 3, open a hole on top, another one cavity side, connecting bleeder pipe 4, bleeder pipe 4 communicates with atmosphere, the pressure of the cavity that is communicated with when suction tude 3 is during greater than ambient pressure, the cavity liquid height that is communicated with suction tude 3 descends, and gas is emitted from bleeder pipe 4, and the pressure of the cavity that is communicated with when suction tude 3 is during less than ambient pressure, the cavity liquid height that is communicated with suction tude 3 rises, and gas enters the cavity that is communicated with suction tude 3 from bleeder pipe 4.The top opening of valve body 1 inner chamber connects a liquid entering hole 5, and the middle part of valve body 1 side and bottom are respectively equipped with a pressure gauge 6 and a liquid discharging valve 7, are provided with a level meter 8 on side of valve body.
Described suction tude 3 can be located at top, side, the bottom of valve body 1 inner chamber, and liquid discharging valve 7 can be located at the middle lower bottom part of valve body 1 inner chamber side, perhaps is located at the below of valve body 1 inner chamber.
