Technical Field

The invention belongs to the technical field of liquid bubble counting, and particularly relates to a gas bubble counter.

Technical Field

At present, most of gas bubble counters in the market display gas amount visually in a liquid bubble counting mode, so that the existence of liquid in the bubble counter is required to be recorded. When the gas end is closed, the liquid in the bubble counter can flow downwards due to gravity, and the key technology of the bubble counter is to prevent the liquid in the bubble counter from flowing downwards. The scheme for solving the problem in the market mostly adopts the principle of a one-way valve, namely a mode of adding a piston to a spring to block an air outlet at the lower part. The gas in the bubble counter is thus prevented from moving downwards and the liquid in the bubble counter is prevented from flowing downwards.

Disclosure of Invention

The invention uses the breathable film made of microporous hydrophobic materials to replace the conventional one-way valve technology, and parts such as a spring, a piston and the like are omitted, so that the aim of preventing liquid in the bubble recorder from flowing downwards is fulfilled.

The technical solution of the invention is as follows:

the utility model provides a gas bubble counter, includes transparent observation tube, and connects in the upper portion connecting seat of this transparent observation tube upper portion and connects in the lower part base of this transparent observation tube lower part: a small hole device is arranged in the observation tube, and a breathable film is arranged between the small hole device and the lower base.

The observation tube can be filled with liquid, such as water, so that bubbles formed when gas flows in the tube can be visually observed.

The air permeable membrane is made of hydrophobic materials, and the aperture of the air permeable membrane is 0.1 nanometer to 100 micrometers. According to different service environments, the breathable film is selected according to corresponding waterproof grade requirements, so that liquid in the observation tube cannot penetrate through the breathable film and is reserved in the observation tube.

The both ends of upper portion connecting seat have the screw thread, one end is used for connecting pneumatic joint, connects outside with the gas end, the other end links to each other with the observation pipe, the lower part of this upper portion connecting seat is equipped with the recess, supplies first sealing washer to place to reach the effect with observation pipe sealing connection.

And a through air hole is formed between the upper end surface and the lower end surface of the upper connecting seat, and a through air hole is formed between the upper end surface and the lower end surface of the lower base.

A hydrophobic breathable film is arranged between the observation tube and the lower base, and the gas on the lower end face of the lower base must pass through the hydrophobic breathable film firstly and then pass through the small hole device. The small hole device is provided with a lower air inlet hole and an upper air outlet hole, and the aperture of the upper air outlet hole is smaller than the inner diameter of the observation tube. Thus, the gas forms a continuous bubble within the liquid entering the sight tube through the upper exit orifice of the orifice means. The size of the air flow can be intuitively judged according to the speed of bubble formation.

Compared with the prior art, the invention has the beneficial effects that:

the air quantity is visually displayed by the way of liquid bubble measurement, so that the existence of liquid in the bubble measuring device is required to be recorded. When the gas end is closed, the liquid in the bubble counter can flow downwards due to the self gravity and the influence of the environment, and the key technology of the bubble counter is to prevent the liquid in the bubble counter from flowing downwards. The prior art mostly adopts the one-way valve principle to solve the problem, namely a mode of adding a piston to a spring blocks an air outlet at the lower part. The liquid in the bubble counter is thus prevented from moving downwards and thus from running downwards. The invention uses the breathable film made of the microporous hydrophobic material to replace the conventional one-way valve technology, omits a spring, a piston and other parts, also achieves the aim of preventing the liquid in the bubble recorder from flowing downwards, and realizes simpler and more economical technology.

Detailed Description

The present invention will be described in further detail with reference to the following examples and the accompanying drawings.

As shown in figure 1, an upper connecting seat 1 of the gas bubble counter is of an internal thread structure and is used for being connected with an external pneumatic connector so as to realize the sealing connection of a gas pipe. The bottom of the lower internal thread is provided with a groove for placing a sealing ring 6 which can be connected with the observation tube 2 in a thread sealing way. The upper connecting seat 1 is unscrewed to add water into the observation tube 2.

The lower base 4 is of an internal thread structure and is in threaded sealing connection with the observation tube 2 through a sealing ring at the bottom. The lower inner thread structure of the lower base 4 can be connected with the micro-flux gas supply end in a sealing way.

The center of the upper end face and the center of the lower end face of the lower base 4 are provided with through vent holes, the vent holes are covered with breathable films 3, and the small hole devices 5 are covered on the breathable films 3 and are bonded and sealed with the lower base 4.

When observing pipe 2 is full of water, little flux gas passes through ventilated membrane 3 by lower part base 4 air vent and gets into aperture device 5, and via the aperture of aperture device 5, gas is released the aquatic in observing pipe 2 by the form of bubble, and the bubble rises and reaches upper portion connecting seat 1.

The gas bubble counter in the embodiment visually represents the micro-flux gas in the form of bubbles. Water in the gas bubble recorder needs a certain osmotic pressure for the water to pass through the hydrophobic breathable film due to the hydrophobic breathable film, and the osmotic pressure is negative in the gas transmission process, so that the water cannot pass through the breathable film 3; after the gas transmission is stopped, the normal atmospheric pressure and the outside are not enough to satisfy the requirement of the osmotic pressure of water passing through the hydrophobic breathable film 3, so that the water is blocked on the breathable film 3.

As shown in fig. 2, an upper connecting seat 1 of the gas bubble counter is of an internal thread structure, and the internal thread of the upper part can be connected with a pneumatic connector to realize the sealing connection of a gas pipe; the bottom of the lower internal thread is provided with a groove for placing a sealing ring 6 which can be connected with the observation tube 2 in a thread sealing way. The upper connecting seat 1 is unscrewed to add water into the observation tube 2.

The lower base 4 is of an internal thread structure and is in threaded sealing connection with the observation tube 2 through a sealing ring at the bottom. The lower inner thread structure of the lower base 4 can be connected with the micro-flux gas supply end in a sealing way.
