A parallel slide gate valve is a kind of valve. It is designed to transmit flow through a piping system. Unlike other sürgülü vana, this type is easy to install and requires little space along the pipe axis.

Bu valf kimya endüstrisinde, petrol endüstrisinde ve doğal gaz endüstrisinde kullanılmaktadır. Genellikle bu valfler dövmedir, ancak döküm de yapılabilir. Sertleştirilmiş metallerden yapılmıştır ve hem açık hem de kapalı sıvı akışı uygulamaları için uygundur.

Bu valfler yüksek dayanıklılığa sahiptir ve temizlenmesi çok kolaydır. Ancak dikkatli bir şekilde açılıp kapatılmaları gerekir. Sızdırmazlık mekanizmasının doğası gereği, koltuğun düzgün oturduğundan emin olmak önemlidir. Yatak deforme olursa, sıvının basıncı bir sızıntıya neden olabilir.

Are Parallel Slide Gate Valves Easy to Operate?

Paralel sürgülü sürgülü vanaların kullanımı çok kolaydır. El çarkı, pnömatik aktüatörler veya elektrik motorları ile çalıştırılabilirler. Operatör çarkı kullanarak mile tork uygular.

Sonuç olarak, vananın çalışma özellikleri diğer sürgülü vanalara benzer. Bunun nedeni, valfin düşük enerji ile çalışmasıdır ve bu da pompalama işlemini daha verimli hale getirir.

Paralel sürgülü sürgülü vana kullanmanın birçok avantajı vardır. En önemlilerinden biri, tüm bir yüzeyi kapatma yeteneğidir. Diğer bir avantajı da yangına dayanıklı hale getirilebilmesidir.

Paralel Sürgülü Vana Nasıl Çalışır?

Paralel sürgülü sürgülü vanalar, boru sistemlerinde sıvı akışını kontrol etmek için kullanılır. Bir boru sisteminin izolasyonunu sağlarlar ve kimya ve enerji üretim endüstrilerinde yaygın olarak kullanılırlar. Valfler pnömatik veya elektrik motorları ile tahrik edilebilir. Kompakt tasarımları, onları boru hatlarında kullanıma uygun hale getirir.

Valf, hem yüksek hem de düşük basınç koşullarında sızdırmazlığını korumak için tasarlanmıştır. Ayrıca çok yüksek sıcaklıklarda servis için uygundur. Anti-statik bir tasarım da sağlanır. Yangına dayanıklı bir tasarım için esnek bir grafit conta da kullanılır.

Valf üzerindeki yaylar, yukarı ve aşağı oturma düzenini kayar temas halinde tutar. Bu çalışma torkunu azaltır. Basınç tahliye edildiğinde, valf yatağı otomatik olarak sıfırlanır. Bu sayede tüm yüzeyde sızdırmazlık sağlanır.

Where Are Parallel Slide Gate Valves Used?

A parallel slide gate valve is a type of valve used to control fluid flow in a piping system. The valve is made of two discs that are connected through a stem. 

It is mainly used for regulating fluid flow in oil and gas applications. These types of valves are easy to disassemble, clean, and repair.

A parallel slide gate valve can be driven by an electric motor or a handwheel. 

Normally, the handwheel is placed above the stem and the valve can be operated manually, pneumatically, or electro-hydraulically. 

Moreover, parallel slide gate valve applications include the following:

1. Power Generation

Parallel slide gate valves find extensive applications in power plants, particularly in steam and water systems. 

They play a crucial role in regulating and isolating fluid flow within power generation processes, ensuring efficient and controlled operation.

2. Petrol ve Gaz Endüstrisi

In the oil and gas sector, parallel slide gate valves are employed for various purposes, including flow control and isolation in pipelines. 

Their robust design and reliable performance make them suitable for handling the challenging conditions often encountered in oil and gas operations.

3. Refining and Petrochemicals

In refining and petrochemical facilities, parallel slide gate valves are utilized for controlling the flow of different fluids in refining processes. 

Their ability to handle high temperatures and pressures makes them well-suited for applications where precise control and tight shut-off are essential.

4. Water Treatment Plants

Parallel slide gate valves are integral components in water treatment plants. 

They are employed for regulating the flow of water in different stages of the treatment process, ensuring effective treatment and distribution of clean water to various points in the system.

5. Chemical Processing

Chemical plants often use parallel slide gate valves for managing the flow of various chemicals and fluids in different stages of the production process. 

The valves’ design allows for reliable and precise control, contributing to the efficiency and safety of chemical processing operations.

6. HVAC Sistemleri

Heating, ventilation, and air conditioning (HVAC) systems incorporate parallel slide gate valves for controlling the flow of air, water, or other fluids. 

These valves help in maintaining optimal conditions within HVAC systems, contributing to energy efficiency and temperature control.

7. Marine and Shipbuilding

In marine and shipbuilding applications, parallel slide gate valves are utilized for controlling fluid flow in different systems onboard vessels. 

Their durable construction and ability to withstand harsh marine environments make them suitable for marine engineering.

8. General Industrial Applications

Parallel slide gate valves find widespread use in various industrial settings where precise flow control, reliable shut-off, and durability are paramount. 

Their versatility makes them valuable in diverse applications across different industries, contributing to efficient and safe fluid-handling processes.

Types of Slide Parallel Gate Valves

There are several kinds of parallel slide gate valves. These depend on torque force to wedge the disc into the valve body. 

Moreover, common types of slide parallel gate valves include rising stem and non-rising stem variations. 

bu rising stem design features a stem that moves upward when the valve is opened, providing a visual indication of the valve’s status. 

In contrast, non-rising stem valves have a stem that remains stationary while the gate moves. 

Both types are available with various materials and configurations to suit different applications, offering reliable performance in industries such as power generation, oil and gas, water treatment, and more.

Are Slide Parallel Gate Valves Easy to Install?

Generally, parallel-slide gate valves are compact and easy to install. Their elongated stem prevents thermal deformation and ensures strong sealing. 

With their wide flat seating, they minimize the effect of minor damages on the surface.

Parallel slide gate valves are often used for applications requiring high differential pressure. 

However, they are not recommended for service under hazardous conditions.

Anahtar Paket Servisi

Parallel slide gate valves are pivotal in industries like power generation, oil and gas, and water treatment. 

They come in rising and non-rising stem variations, providing flexibility for diverse applications. 

The rising stem offers visual indication, while the non-rising stem caters to space constraints. 

Both types boast robust construction and versatility, making them reliable choices for controlling the flow of liquids in critical processes, ensuring operational efficiency and durability in demanding environments.
