Industrial valves are a part of refinery equipment
A refinery is a center or a process that refines materials or converts raw materials into other products. Refineries have equipment that can be used to are easy to use. In this article, we will take a look at refinery equipment, so stay with us.
Refinery valves The first equipment that can be mentioned for a refinery is valves. The valve is a device It is said that it is used to control the flow and pressure of fluids. The valve is actually a device that is used to completely connect and disconnect the flow of gas and liquid, adjust the amount of passage required for liquids, prevent and prevent the return of liquids and Similarly, it is used to regulate the amount of liquids. In addition, other important tasks of valves include controlling and keeping pressure devices safe. In this article at
Oil Pasargad We will take a look at it .
Refinery equipment: different models of valves
In terms of efficiency, industrial valves are divided into three categories, which are:
\ n
- Manual valves that require human power to work (Manual Valves)
- Automatic valves that use fluid forces Air and gas are controlled (control valves)
- updated and automatic valves that have electric power to operate (Solenoid)
Important factors in choosing faucets
In order to be able to choose the right milk for refinery work, you should pay attention to several points; The first is a plumbing map to know where it came from and where it went. The second thing you have to do to choose the valves is to consider the type of work, as well as to be able to consider the temperature and pressure, and finally, consider the material of the valve.

Gate or sliding valve inspection
Sliding or gate valves are used in places where you want to completely open and close the fluid flow; One of the most important features of this valve is that when the valve is fully open, its drawer or stopper goes completely up and out of the way of the flow, and there is no pressure against the flow. when the valve is closed; It goes to its lowest place; Therefore, the fluid has caused the pressure to drop due to the change in direction. This type of valve consists of various parts, first of all, it can be pointed to its proper opening and closing. Of course, we must say that it is more difficult to accurately adjust the amount of liquid and gas. It is spherical in shape and its structure is designed in such a way that the liquid changes 180 degrees from the point of entering the valve to its exit. Hence, the non-opening of the ball valve does not have a series of problems compared to the half-open sliding valve, and hence it is a good option to adjust the flow. The number of turns of the valve handle with the volume of the liquid outlet makes it very convenient and easy to adjust the amount of flow by hand. h4>
- Changing the direction of the fluid flow in contrast to the sliding valve
- Changing the direction of the flow in case of turbulence
- Increased pressure drop in case of turbulence
- Increased pressure compared to sliding valve
- produced Usually made of nickel or stainless steel.
Let's develop a samouri, it is used to completely connect and disconnect the tap. In other words, when the valve is fully open, it moves in a straight line without hitting an obstacle in the duct that is connected to the pipe, and then when the pressure drop is low and the size of the sliding valve, in this valve model, the friction between The body and the valve are raised and opening and closing it will face problems.
Ball valve
Another model of valve It is useful for connecting and disconnecting the valve. A quarter of the cycle of the valve is opened or closed, and when the valve is open, the material in its line moves without hitting the obstacle, as much as the pipe connected to it, this valve model is soft and smooth and works with very little force. he does; This valve is when it gets out of control. This type of valve has various types, among which we can refer to the floating ball valve mounted on the rotating axis.
