How does a controlled small hole float valve work?

The float always has to float on the water, and when the water is **, the float also rises.

When the float rises, the connecting rod also rises.

The connecting rod is connected to the valve at the other end, and when it rises to a certain position, the connecting rod supports the rubber piston pad to close the water source.

When the water level drops, the float also drops, and the piston pad opens when it dries.

The full name of the small hole float valve is the small hole hydraulic float valve, and the top small float valve controls the water, and only the float can be seen on the water surface when the water level height is reached. The hydraulic structure is mainly resistant to high pressure, saving installation space, and the rod and float are relatively small.

Action: The water inlet end (at least 1 kg water pressure) jacks open the water from the large piston in the valve cavity - the liquid level holds up the stainless steel float after the water is full - the small float valve on the top closes the water - the water inlet end is consistent with the pressure in the valve cavity - the large piston stops the water inlet through the spring return.

Now the most used is the stainless steel float valve, when it is closed, it means that the float has been lifted by the liquid and reached the liquid level height; As long as the liquid level drops and the inlet continues to feed liquid, this valve will maintain a continuous water replenishment state (simply put, the liquid level drops, the water level rises, the water is turned off, the liquid level drops, and the water is replenished. Keep repeating. It is also easy to maintain, and now the float structure is very strong.

Dear, hello, the functions of the small and large holes of the hydraulic float valve are as follows:1Small holes (also known as trigger holes):

When the liquid level is lower than the minimum water level set by the valve, the valve sucks the liquid into the valve body through a small hole, causing the liquid level to rise, and then triggering the valve to open. Therefore, the small hole plays the role of triggering the opening of the valve. 2.

Large hole (also known as inlet hole) Wangshou: When the valve is opened, the large hole allows the liquid to flow into the inside of the valve body from the storage tank or pipeline, and at the same time adjusts the or ifice size of the large hole outlet, which can control the opening and closing speed of the valve and avoid problems such as excessive pressure or excessive noise caused by excessive flow. In summary, the small hole and large hole are important design elements in the liquid ant pressure float trapped object suspect valve, and the normal operation of liquid level control and flow regulation can be realized through their cooperation.

Dear, according to your description, I am giving you the answer --- what is the role of a small hole and a large hole of the hydraulic float valve Small hole: When the hydraulic float valve is closed, the small hole plays the role of emptying the mass such as air. Before the valve is closed, the air in the pipe is exhausted through a small hole to ensure that the hydraulic float hole valve can work properly when activated.

Large bore: When the hydraulic float valve is opened, the large bore allows the liquid to pass through the valve quickly and quickly establishes sufficient flow. In addition, macropores can also improve system efficiency by reducing resistance and reducing pressure collapse losses for liquid flow.

1. The principle of ball valve operation is to control the opening or closing of a valve by relying on the reduction and increase of the float in the float chamber to control the opening or closing of a valve. The float chamber is placed on the side of the flooded evaporator, and the upper and lower balance pipes are communicated with the evaporator, so the liquid level height of the two is the same.

2. When the liquid level in the evaporator drops, the liquid level of the float chamber also drops, so the float brother descends, and relies on the lever to increase the opening degree of the valve and increase the liquid supply. Vice versa.

Summary. The function of the small needle valve seems to be to protect, for example, the diaphragm valve is mainly used for the steam turbine to drain the EH oil pressure, the needle valve is opened, and the EH oil pressure is discharged. A needle valve is a type of fine-tuning valve with a needle-shaped plug that is mainly used to regulate airflow.

The function of the small needle valve seems to be to protect it, for example, the diaphragm valve is mainly used to dissipate the EH oil pressure of the steam turbine, the needle valve is opened, and the EH oil pressure is discharged. The needle valve is a kind of fine-tuning valve, and its plug is needle-shaped, which is mainly used to regulate the airflow.

The carburetor is a relatively simple oil supply system, which is mainly composed of three parts: float chamber, plunger and shell, in which the plunger part controls the oil intake, and the float chamber reserves the amount of fuel. Its function is to ensure that the engine works under medium and medium loads, and to supply the mixture, which gradually thins with the increase of throttle opening. The timing of the work is to be in working condition except for the idle condition.

The function of the carburetor is to vaporize the gasoline according to the needs of the engine in different situations, and mix it with air in a certain proportion to form a combustible mixture. Enter the cylinder in a timely and appropriate amount.

Starter, idling, medium-load, full-load, accelerator, and carburetor are mixtures that produce gas with matching concentration and quantity according to the different rotations of the engine. Therefore, when the engine is at different speeds such as idling, low, medium, and high speeds, the concentration and amount of mixed gas of the carbureto** are also adjusted. The role of the main oil supply system is :

When the engine is from a small load to a large load, the beam plate increases with the opening of the throttle, and the mixture becomes thinner from thick to thin. The thickening system is mainly to provide additional fuel at high load or full load, which is the maximum power emitted by the engine. The carburetor will automatically mix out the corresponding concentration according to the different working state requirements of the engine, and output the corresponding amount of mixture, in order to make the mixture mix more uniformly, the carburetor also has the effect of atomizing the fuel for the normal operation of the machine.

The small needle valve on the float hydraulic water level control valve plays a protective role. The float type hydraulic water level control valve has the function of automatically opening and closing the pipeline to control the water level, which is suitable for various water (pool) automatic water supply systems in industrial and mining enterprises and civil buildings, and can be used as a circulating water supply control valve for atmospheric boilers. Float type hydraulic water level control valve is small in size, easy to install, high in sensitivity, small in head loss, no water hammer phenomenon, because the small float control can greatly improve the utilization rate of the water tower, for the new water tower due to the reduction of the float volume and the upper part of the water tower is left to the float to float freely, the required height is reduced, and the cost of the water tower is reduced.

Overcoming the disadvantages of the old rod float ring valve such as large size, easy damage, low working pressure and large amount of overflow, it is the most ideal and suitable product for building new water towers and replacing old float valves. Working principle of hydraulic water level control valve:1

Hydraulic control valve is a kind of hydraulic control valve that automatically controls the liquid level height of the water tank and water tower. When the water surface drops more than the preset value, the float valve is opened, the pressure of the upper chamber of the piston is reduced, and the pressure difference between the piston and the piston is formed. When the water level rises to the preset height, the float valve is closed, and the pressure in the upper chamber of the piston continues to increase, causing the disc to close and stop the water supply. In this way, the reciprocating automatic control of the liquid level at the set height realizes the function of automatic water supply.

2.The hydraulic water level control valve plays the role of a water supply control valve in the atmospheric boiler cycle. Its working principle is mainly manifested in:

When the water level in the pool or water tower drops, the float valve opens and drains, there is pressurized water in the water inlet pipe to hold up the piston in the valve, the sealing surface is opened, the valve is opened for water supply, when the water level rises to the control valve, the float valve is closed, the live cavity beam plug moves down to close the sealing surface, and the valve stops the water supply. 3.The hydraulic water level control valve has the function of automatically opening the valve pipeline to control the water level, which is suitable for various water tower (pool) automatic water supply systems in industrial and mining enterprises and civil buildings, and can be used as a circulating water supply control valve for atmospheric boilers. To overcome the disadvantages of the old-fashioned rod float valve such as large volume, easy damage, low working pressure, and a large amount of overflow, it is more suitable to build a new water tower and replace the old-fashioned float valve.
