Abstract

Provided is a positive/negative pressure protection device with water condensation function, comprising a tank body. The inner cavity of the tank body is provided with two vertical baffles which divide the tank body into three cavities. One baffle is provided with a vent and the other is arranged at interval with the bottom of the tank body inner cavity. One cavity is communicated with a gas pipeline and the middle and the bottom parts of the side face of the tank body are respectively provided with a pressure gauge and a drain valve, and the bottom of the tank body is provided with an overflow pipe. The upper side face of one of the two cavities is provided with a hole communicated with a drain tube, and the upper part and the bottom of the tank body inner cavity are respectively connected to a liquid inlet and a drain valve, and the side face of the tank body is provided with a liquid level gauge. The utility model is advantageous in that too much condensed water will automatically overflow; the maximum and minimum pressures of the container can be controlled; a plurality of containers can be protected at the same time; water condensation can be conducted to a plurality of pipelines and automatic water discharge can be achieved; the adoption of liquid seal prevents jam and leakage; the protection device can be applied in the conveying of gas like biogas and natural gas.

Description

A kind of have a with fixed attention positive negative pressure protective gear of water function

Technical field

The utility model relates to and coagulates that water section has automatic spilling water function and positive negative pressure protective gear adopts two-way fluid-tight principle in a kind of anti-PNPB control valve unit, especially this device with water function with fixed attention.

Background technique

At present, the condensed water in the condenser that is provided with in biogas engineering and the natural-gas transfer pipeline need manually discharge water, and when condensed water in the condenser reaches a certain amount of, need open valve unnecessary moisture content is emitted.Check valve apparatus and mechanical type breather valve device are widely used in the flexible gas holder of stored-gas and steel tank.One-way valve can only reduce the pressure in the container; if the pressure in the container is lower than ambient pressure; this moment, one-way valve was ineffective; at this time in order to protect the Security of container; need to use the mechanical type breather valve device to avoid container because that negative pressure causes is sunken; the mechanical type inhalation valve is to utilize the container inner pressure difference of the gravity of valve and stored-gas to guarantee the safety of container, but there is the problem of jam and leakage in actual applications in this device.The defective of above-mentioned several parts exists inconvenient operation and potential safety hazard in application.

The model utility content

The purpose of this utility model provides the device that a kind of easy to operate, good airproof performance, safe collection coagulate water and positive negative pressure protection dual functions.

A kind of have with fixed attention the positive negative pressure protective gear main body of water function and form for the tank body of sealing; it is characterized in that described tank inner chamber is provided with two vertical baffle plates; leave ventilating hole on one of them baffle plate, the gap is left in another baffle plate and tank inner chamber bottom, and two baffle plates are divided into three cavitys with tank body.One of them cavity is communicated with suction port, and the middle part of the side of this part tank body and bottom are respectively equipped with a pressure gauge and a liquid discharging valve, and is provided with overflow pipe in the bottom; A hole is opened on top, a cavity side in other two cavitys, is communicated with bleeder pipe, and the tank inner chamber top is connected a liquid entering hole and liquid discharging valve with bottom difference opening, and a level meter is housed in the side of tank body.

The utility model has following advantage: when too much condensed water enters tank body condenser part, can go out from the spill pipe automatic overflow; Pressure maximum that container needs and pressure minimum can be realized control, precision height according to the height of the liquid level of adjusting positive negative pressure protection chamber; This device can be protected a plurality of containers simultaneously, and can be simultaneously coagulate water and discharge water automatically a plurality of pipelines; The fluid-tight mode that this device is taked has been avoided the jam and the easy problem of leaking of mechanical breather valve in the past; Simple in structure, processing and easy for installation, cost is low.This device can be widely applied to gas transmission pipelines such as biogas and rock gas, has promotional value.

Among the figure: 1 steam outlet pipe, 2 liquid entering holes, 3 baffle plates, 4 bleeder pipes, 5 positive negative cavities, 6 positive negative cavities, 7 level meters, 8 baffle plates, 9 liquid discharging valves, 10 liquid discharging valves, 11 overflow pipes, 12 suction ports, 13 coagulate water cavity, 14 pressure gauges

Embodiment

A kind of have with fixed attention the positive negative pressure protective gear main body of water function and form for the tank body of sealing, it is characterized in that described tank inner chamber is provided with two vertical baffle plates 3 and baffle plate 8, leave ventilating hole on one of them baffle plate 8, another baffle plate 3 leaves the gap with the tank inner chamber bottom, baffle plate 3 and baffle plate 8 are divided into positive negative cavity 5 with tank body, just negative cavity 6 and water cavity 13 with fixed attention, one of them coagulates water cavity 13 and is communicated with suction port 12, the middle part of the side of this part tank body and bottom are respectively equipped with a pressure gauge 14 and a liquid discharging valve 10, and be provided with overflow pipe 11 in the bottom, coagulate in the water cavity 13 when ducted condensed water enters, too much moisture content can overflow automatically from overflow pipe 11; A hole is opened on positive top, negative cavity 5 side; being communicated with bleeder pipe 4 communicates with atmosphere; when the overpressure in the tank body; liquid level in the positive negative cavity 6 descends; positive negative cavity 5 liquid levels rise; gas can be emitted from bleeder pipe 4; when the hypotony in the tank body; positive negative cavity 5 liquid levels descend; positive negative cavity 6 liquid levels rise, and ambient atmos will enter in the jar by bleeder pipe 4, container has been played the effect of a protection; the tank inner chamber top is connected a liquid entering hole 2 and liquid discharging valve 9 with bottom difference opening, and a level meter 7 is arranged in the side of tank body.
