Urban heating valves: In urban heating systems, a large number of metal sealed butterfly valves, horizontal balance valves and directly buried ball valves are needed. Because of these valves, the longitudinal and transverse hydraulic imbalance of the pipeline can be solved, thus achieving energy saving and heat balance.

1. Urban gas valves: Urban gas accounts for 22% of the total natural gas market. The number of valves is large and there are many types.

The main requirements are ball valves, plug valves, pressure reducing valves and safety valves.

2. Urban heating valves: In urban heating systems, a large number of metal sealed butterfly valves, horizontal balance valves and directly buried ball valves are needed. Because of these valves, the longitudinal and transverse hydraulic imbalance of the pipeline can be solved, thus achieving energy saving and heat balance.

The purpose.

3. Urban construction valves: Low pressure valves are commonly used in urban construction systems and are being developed in an environmentally friendly and energy efficient manner.

Environmentally friendly rubber plate valves, balance valves, medium line butterfly valves and metal seal butterfly valves are gradually replacing low pressure iron gate valves.

Domestic urban construction needs valves, such as balance valves, soft seal gate valves and butterfly valves.

4. Environmental protection valve: In domestic environmental protection system, the water supply system mainly needs middle-line butterfly valve, soft seal gate valve, ball valve and exhaust valve (used to remove air in the pipeline).

Soft seal gate valve and butterfly valve are needed in sewage treatment system.

5. Long haul pipeline valves: Long haul pipelines are mainly crude oil, finished products and natural pipelines.

Valves that require a large number of such lines are forged steel three-piece full-diameter ball valves, sulphur-resistant plate gate valves, relief valves and check valves.

6. Valves for petrochemical plants:

a. Refining equipment. Most valves used in refining equipment are pipeline valves, including gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves and steam traps. Gate valves account for about 80% of the total. Number of valves.

(Valves account for 3% to 5% of the plant's total investment).

b. Chemical fiber equipment, chemical fiber products mainly include polyester, acrylic and Vinylon.

Ball valves and jacketed valves (jacketed ball valves, jacketed gate valves, jacketed globe valves), for valves.

c, acrylonitrile plant.

This equipment generally requires the use of api standard production valves, mainly used for gate valves, globe valves, check valves, ball valves, traps, needle valves, plug valves, of which gate valves account for about 75% of the total number of valves.

d) Ammonia plant.

Due to different ammonia synthesis and purification methods, different technological processes, the required valve technical performance is also different.

At present, domestic ammonia plants mainly need emergency shut-off valves, gate valves, globe valves, check valves, traps, butterfly valves, ball valves, diaphragm valves, regulating valves, needle valves, safety valves and high temperature and low temperature valves.

Among them, the globe valve accounted for 53.4% of the total valve data of the device, gate valve accounted for 25.1%, trap accounted for 7.7%, safety valve accounted for 2.4%, control valve and low temperature valve and other 11.4%

. e, ethylene plant. Ethylene plant is a major plant in the petrochemical industry. It requires a wide variety of valves.

Gate valves, globe valves, check valves and lever ball valves make up the majority. Gate valves need heads.

"In addition, large vinyl and high-pressure polyethylene installations require ultra high temperature, low temperature and ultra high pressure valve families.

f, air separation device.

\ \

g, polypropylene device, polypropylene is easy to use propylene as raw material, polymer polymer compounds, the device mainly needs gate valve, globe valve, check valve,

Needle valve, ball valve, trap.

7. Power station valve: The construction of power stations in China is moving in the direction of large-scale development. Therefore, large diameter and high pressure relief valves, pressure reducing valves, globe valves, gate valves, butterfly valves, emergency shut-off valves, flow control valves and ball sealing instruments are required.

Close the valve.

8. Metallurgical valves: The behavior of alumina in the metallurgical industry requires the use of wear-resistant slurry valves (in flow-through globe valves) and the adjustment of traps.

Metal sealed ball valves, butterfly and oxidized ball valves, globe valves and four-way directional valves are mainly used in the steel industry.

9. Offshore Platform valves: With the development of offshore fields, the number of valves required for offshore leveling has increased.

Offshore platforms require offshore valves, check valves and multiway valves.

10. Food and pharmaceutical valves: The industry mainly needs stainless steel ball valves, non-toxic all-plastic ball valves and butterfly valves.

Of the 10 large valve products listed above, the demand for general purpose valves is much higher, such as instrument valves, needle valves, gate valves, globe valves, check valves, ball valves and butterfly valves.
