Valve product push

The valve is a control component in the fluid delivery system and has functions such as cut-off, regulation, diversion, reverse flow, pressure regulation, diversion, or pressure relief. With the continuous development of valve technology, the continuous expansion of valve applications, and the corresponding valve standards are becoming more and more indispensable. China's first mandatory national standard for valve products, "the valve shell minimum wall thickness size requirements This also led to the specification. The implementation of the national standards for valve products of the Ministry has become a mandatory requirement, which ensures the safety of product equipment and personnel to the maximum extent.

According to industry sources, with the increasingly fierce market competition in China's pump and valve industry, pump and valve companies can only effectively and clearly understand the status quo of the industry, continuously strengthen and optimize their own products, strengthen their sense of crisis, strengthen corporate culture and market service concepts, and only achieve stability. Seeking for quickness, quickness and refinement, and seeking stability in precision can enable companies to survive and develop in the increasingly fierce competition in the pump and valve industry. This topic will take you into the valve industry, to appreciate the development of the industry, market trends.

product description

The valve is composed of a valve body, a valve cover, a valve flap and a spring, and is mainly used for the outlets of pipes of water supply and drainage systems, petroleum, chemical industry and other industrial sectors to prevent the medium from flowing backwards. Due to the inclined design of the seal ring of this product, the closing time is short and the water hammer pressure can be reduced. The valve flap is made of nitrile rubber and steel plate after being pressed at high temperature. It is resistant to erosion, good sealing performance, simple product structure, convenient maintenance, maintenance and transportation.

product description

New lining hot air valve In order to realize advanced ironmaking technology such as oxygen enriched coal injection, the air temperature must be increased to 1200°C, and the air temperature at the outlet of the hot air furnace must be above 1300°C. To this end, we have developed a new type of lining hot air valve. Its excellent performance is as follows:

1. Absorb the advanced technology of high temperature valves from Japan and Germany. The valves of the key parts of valves are treated with a multi-component co-permeation protection layer to increase the high-temperature oxidation temperature of carbon steel to over 1000°C, which greatly prolongs the service life.

2. The sealing surface of the key parts of the valve is a composite high-temperature corrosion-resistant stainless steel coating and is subjected to enhanced cooling, no deformation, and stable sealing performance.

3. The valve stem adopts a floating seal, which is tightly sealed and moves to keep the lifetime of a generation of valves from leaking, thus reducing maintenance workload.

4. The semi-elliptical asymmetrical water cavity structure is adopted in the valve body, which eliminates the shortcomings of the weld leakage in the circular water cavity structure and greatly improves the overall structural strength of the valve.

product description

I. Overview ZJK-DXF electronic high-pressure one-way valve is our company's patented product. It is a safe water injection product developed specifically to prevent the failure of underground rock formation pressure caused by the production of oil in the oil field, resulting in failure of the water injection system caused by sand water anti-spitting in the rock formation. , Can effectively improve the water injection system's automatic security protection capabilities.

Second, the basic characteristics of the use of anti-suppression media, the flow of energy to quickly block the flow channel, while the anti-spit signal to the media through the cable to other relevant electrical control equipment to take measures to prevent accidents.
