Cast steel swing check valves
Y-shaped filters are an indispensable filtering device in pipeline systems for conveying media. Y-shaped filters are usually installed at the inlet of pressure reducing valves, relief valves, constant water level valves, or other equipment to remove impurities in the medium and protect the normal use of valves and equipment. The Y-shaped filter has the characteristics of advanced structure, low re...
The installation of safety valves and the key points of pipeline layout design 1. The safety valve should be installed upright and close to the protected equipment or pipeline. If the arrangement cannot be approached, the total pressure drop of the pipeline from the protected equipment or pipeline to the inlet of the safety valve should not exceed 3% of the fixed pressure value of the safety valve...
1、 What is the principle of a shut-off valve? A globe valve uses the torque of the valve stem to exert downward pressure on the sealing surface, relying on the pressure of the valve stem to tightly fit the sealing surface of the valve disc and the sealing surface of the valve seat, preventing the flow of medium or regulating the flow rate of medium. 2、 What is the scope of application of globe val...
Valves are important components in the pipeline system of petrochemical plants, with a wide variety and large quantity, and are one of the main sources of leakage in the plant. Therefore, the requirements for valve leakage are crucial. The sealing performance of a valve refers to the ability of each sealing part of the valve to prevent medium leakage. The main sealing parts of a valve include the ...
Ball valve is a common type of valve, and its design characteristics make it widely used in various industrial applications. Ball valves are favored for their simplicity, reliability, and ease of operation, playing an important role in fluid control. The main components of a ball valve include a sphere with a diameter and inlet and outlet pipes located on both sides of the sphere. Spheres are usua...
The working principle of pneumatic expansion butterfly valve is to rely on compressed air provided by the air source to cause elastic deformation of the sealing pair inside the valve body, thereby achieving switch control. After the gas source enters the valve body, it is compressed to a certain pressure through a compressor and then sent into the cylinder, causing the piston to move left or right...
Bellows globe valve, also known as bellows sealed globe valve, is designed with automatic roll welding to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem. The internal structure of the bellows globe valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded to the valve stem to prevent process fluid from co...
How to choose valve plasma welding equipment? Background of valve overlay welding Scratches, erosion, and corrosion can all damage the valve sealing surface. The composition and metal structure of sealing materials, surface treatment process, hardness and hardness difference, specific pressure and conformity, and many other factors can all affect the quality of valve sealing surfaces. Each type of...
Maintaining the worm gear ball valve can extend its service life and ensure its normal operation. The following is the correct maintenance method for worm gear ball valves: 1、 Regular inspections: Regularly inspect the appearance and working condition of the ball valve, and promptly handle any damage or abnormal situations. Meanwhile, check if the fastening bolts of the valve are loose and if ther...
