Stainless steel ball valve: how to maintain the stainless steel ball valve
Stainless steel ball valve: Due to the integral structure of stainless steel ball valve, it is smaller, lighter, leak-free and has excellent sealing performance. The sheath is welded together with carbon steel pipe, which has higher pressure resistance and rigidity. It has better heat insulation and cold resistance than castings. The diameter of the valve is the same as the diameter of the pipeline, which can effectively prevent the heat loss of the medium in the pipeline, and the maintenance method of the stainless steel ball valve.
1. Keep the external and moving parts of the stainless steel ball valve clean
Stainless steel ball valve manufacturer learned that the appearance of stainless steel ball valves, the trapezoidal threads on the stem and stem nut, the sliding part of the stem nut and the bracket, gears, worm gear and other parts are prone to depositing a lot of dust, oil, media residues and other dirt, causing wear and corrosion on the stainless steel ball valve. Therefore, stainless steel ball valves should always be kept clean. Usually, the dust on the stainless steel ball valve can be swept with a brush and compressed air, or even swept with a copper wire brush until the working and mating surfaces show a metallic luster and the painted surface shows the original color of the paint. In addition, stainless steel ball valve manufacturers recommend opening the bottom plug of the flushing valve and trap for flushing periodically, or removing it for flushing periodically to avoid clogging the stainless steel ball valve with dirt.
2. Keep the stainless steel ball valve lubrication
Bearing parts of the meshing parts, gears and worm gears and other mating parts need good lubrication conditions to reduce friction between each other and avoid mutual wear. For the lubrication of parts that agree to be damaged during operation, the manufacturer recommends repairing the lubrication system and smooth oil path. Normally open high-temperature stainless steel ball valves apply every week to a month for oiling, so that the lubricated parts to expose the surface.
3. Responsible for the daily maintenance of the electrical assembly
Cost-effective, maintenance of the electrical assembly, as usual, no less than once a month. Maintenance content: clean appearance, no accumulation of dust, assembly without steam and oil; sealing surface and sealing point should be firm and accurate. In addition, it should be maintained without leakage, so it is considered that the lubrication parts should be oiled according to the regulations, and the valve nut should be oiled. In addition, the electrical parts are complete, good design of the missing phase, active switch, thermal relay does not trip, the indicator is accurate.
In general, in order to maintain the stainless steel valve well, it is necessary to operate in accordance with the above-mentioned methods of the stainless steel valve manufacturer, i.e., cleaning the stainless steel valve well, keeping the stainless steel ball valve lubricated, and performing routine maintenance on the electrical assembly of the stainless steel ball valve.
Ltd. is mainly engaged in the following products: open stem soft seal gate valve, flange butterfly valve, electric butterfly valve, pneumatic butterfly valve, stainless steel gate valve, stainless steel ball valve, etc. It is a seismic bracket manufacturer with modernized, scientific and diversified production, R&D and sales enterprises of valves, seismic brackets and water treatment equipment. Seismic bracket brand and other supporting complete, from a single product, talent shortage of valve company, step by step steady, relying on the meticulous attitude to quality gradually growing excellent quality, technology first, innovation and pragmatic, integrity management, is our company's business philosophy. We will cooperate with you sincerely with good products, perfect service and reasonable price, and create a brilliant tomorrow of Chinese valve industry together.
Nationalization is a trend, and there are some localization requirements in some projects. What are your experiences or views on control valve localization? There are actually more localization requirements involved in our work. We require designers to treat imported products and domestic products equally, unless for some special control valve products can not be manufactured in the country recommended the use of foreign brands, generally or domestic brand control valves. For special control valve products, generally in the engineering design, in order to produce a smooth start and operation of the device, the design will generally follow the views of the patent holder to choose a similar device in the use of performance, and in similar devices on the application of good valve products. About localization, now many direct users of the plant, taking into account the convenience of imported valve repair and maintenance, as well as cost factors, will choose some domestic manufacturers to provide inspection and maintenance services for imported valves, but also when the device used in the import control valve problems, in order not to affect production, in the rework waiting process, the use of domestic brand products as an emergency, once the product can cope with this working condition, the use of good Thus also test the reliability of the product, for the future in the same working conditions of the national brand valve application has laid the foundation. Now there are many enterprises that used to do valve maintenance, have accumulated experience in the practical application, the development of the valve production enterprises, to make a contribution to the localization of valves. For domestic valve manufacturers, how to win the trust of the owners is crucial. We now have many projects, are private entrepreneurs to invest in the construction of its cost control requirements are relatively high, the use of localized products in the project also accounts for most. Now many large state-owned enterprises construction projects, have the requirement of localization rate, which also creates a good environment for domestic products to replace imported brands, therefore, domestic enterprises as long as the strengthening of product quality standards requirements, strengthen the internal management of enterprises, continuous technological innovation, to provide good pre-sales and after-sales service, will be able to obtain the trust of the owners, so that the good development of enterprises.
in transport and storage, the gate valve gate and shut-off valve flap should be closed, the plug pathway should be fully open, the check valve flap should be closed and fixed. Both ends of the pathway should be closed firmly. Packaging of various products should be done in transport and storage without damage.
In July 2008, ARC Consulting Group senior analyst Mr. David Clayton (David Clayton) in the "Control Valve Worldwide Outlook" article: based on the rapid growth of the global control valve market in 2006, 2007 two years, forecast the next five years, the global control valve market will maintain a 6% compound annual growth rate. Control valve market will maintain a compound annual growth rate of 6%, based on 2007 global control valve market sales of $4.8 billion, by 2012, the global control valve market is expected to exceed $6.4 billion (Figure below).
Seismic brackets are used for a wide range of applications, including water supply and drainage for engineering buildings, natural heating and central air conditioning, electrical equipment, natural gas, fire safety, etc. Therefore, the engineering and construction regulations for seismic brackets will be more stringent.
Stainless steel ball valve has the function of heat preservation and cold preservation. Designed and manufactured according to national standards, petroleum, chemical, metallurgical and pharmaceutical industries are used according to 79-94 standards. Stainless steel ball valve adopts steam jacket insulation.
Seismic bracing manufacturer: Seismic bracing is a member or device that limits the displacement of mechanical and electrical engineering auxiliary facilities, controls the vibration of the facilities, and transfers the load to the load-bearing structure.
