Abstract
The utility model relates to a liquid box with constant discharge velocity for controlling liquid flow velocity. A connection pipe is inserted into the liquid box and an air valve is arranged in the box body. When draining, a constant flow velocity is ensured to overcome the defect that the drainage rate of the ordinary liquid box relates to the storage capacity of it.
Description
When the utility model was a kind of discharge liquid, its mass rate of emission can keep constant liquid case, belonged to the device of controlling liquid flow velocity.
Common liquid case, because the influence of liquid body deadweight, when discharge liquid, its mass rate of emission is relevant with the storage liquid measure, it is constant that mass rate of emission can not keep.
The purpose of this utility model is: design a kind of manual shift that need not and also need not the novel liquid case that additional other devices can obtain constant emission speed.
This liquid case is made of casing, communicating pipe, air valve, draining pipe and control cock.Communicating pipe inserts from the casing top, and air valve is contained in the casing top, and draining pipe picks out from the bottom, and control cock is housed on the draining pipe.Close control cock, open air valve, liquid during discharge liquid, closes gas check valve from pouring into communicating pipe, opens control cock, can discharge, and make its mass rate of emission constant.The utility model only need insert a communicating pipe, and an air valve is housed, and can keep constant flow velocity, thus simple in structure, be easy to realize, easy to use.
Concrete structure of the present utility model is by providing in the accompanying drawing:
Figure is the structural representation of the liquid case that mass rate of emission can be constant.
For ease of understanding the utility model, be elaborated below in conjunction with the embodiment that provides in the accompanying drawing:
Mass rate of emission can be constant the liquid case contain a casing made from metal or plastics (1), communicating pipe (2), draining pipe (4); Communicating pipe (2) inserts from the top of casing (1), and its exit, bottom is positioned at the position down of liquid case, and draining pipe (4) picks out from the bottom of casing (1), and air valve (3) is installed in the top of casing (1); Air valve (3) can be made into float-ball type, also can make switching regulator, and draining pipe (4) is provided with discharge opeing control cock (5), to regulate its flow velocity.Casing (1) and draining pipe (4), communicating pipe (2), the junction of air valve (3) must seal.
Mass rate of emission can be constant the principle of work and the job procedure of liquid case as follows: when the liquid case is irritated liquid, close discharge opeing control cock (5) earlier, and open air valve (3), by communicating pipe (2) in casing (1), irritating liquid.During discharge opeing, close gas check valve (3) earlier, the liquid level in the casing is positioned at communicating pipe (2) when the bottom is above, owing to enter air impassabitity communicating pipe (2) in the casing (1), casing (1) produces certain negative pressure, and negative pressure is just aspirated communicating pipe the liquid in (2).But when the liquid level in communicating pipe is lower than its bottom, air just will enter in the casing (1) under the effect of bar pressure, cause that the interior negative pressure of casing (1) reduces, thereby also just weaken, make communicating pipe (2) interior liquid level go up so again by the swabbing action of negative pressure generation.Go round and begin again like this, just make the flow velocity of discharge opeing keep constant.
Claims (3)
1, the liquid case that a kind of mass rate of emission can be constant, it is characterized in that this liquid case contains casing (1), communicating pipe (2), air valve (3), draining pipe (4) and control cock (5), communicating pipe (2) inserts from the top of casing (1), its bottom outlet is in the position down of liquid case, draining pipe (4) picks out from the bottom of casing (1), air valve (3) is installed in the top of casing (1), and draining pipe (4) is provided with control cock (5).
2, liquid case according to claim 1 is characterized in that air valve (3) is a float-ball type.
3, liquid case according to claim 1 is characterized in that air valve (3) also can be a switching regulator.
