PBQ340F、PBQ340HThe development of new valve products in the European hemisphere is a success in absorbing advanced valve products at home and abroad On the premise of the advantages and disadvantages of valves, butterfly valves, gate valves and other valves, all domestic innovative products developed with reference to similar products in Germany are used for reference. The appraisal conclusion points out that in some aspects, the performance is better than the similar products such as gate valve, globe valve and ball valve. The eccentric hemisphere valve can be overlaid with different alloys according to the needs of users. The selection of bimetal seal ring can be used in different industrial departments which require strict sealing, such as wear resistance, corrosion resistance, high temperature resistance, etc.

It is by rotating the valve chain to make the valve unblocked or blocked. The ball valve has the advantages of light switch, small volume, large diameter, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often in closed state and are not easy to be eroded by medium, so they are widely used in various industries.

1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe.  
2. Simple structure, small volume and light weight.  
3. It is compact and reliable. At present, the sealing surface material of ball valve is widely used with good sealing performance, and it has been widely used in vacuum system. 4. It is easy to operate and fast to open and close. Only 90 ° rotation is needed from full opening to full closing, which is convenient for remote control.  
5. The maintenance is convenient, the ball valve structure is simple, the sealing ring is generally movable, and it is convenient to dismantle and replace.  
6. When the valve is fully open or closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the medium will not cause erosion of the valve sealing surface.  
7. Wide range of application, diameter from small to several millimeters, large to several meters, from high vacuum to high pressure.

1、 Sealing pair (valve core, valve seat) - bimetallic, realizing hard sealing of metal spherical ring, fireproof and explosion-proof
2、 The sealing of valve core and valve seat is spherical line contact, and zero leakage is realized by three-dimensional eccentricity
3、 The valve core of the sealing pair has a compensation amount. When the valve is used for a long time, it is only necessary to loosen the limit bolt at the hand wheel side and turn it a little when closing, which can still achieve reliable sealing and prolong service life.  
4、 It can screw off the compression sleeve, adjust or replace the valve seat, and the valve can still be used, so as to avoid the defect of scrapping the whole set after the sealing failure of many existing valves. According to the application, the hemispherical valve products of Shanghai Europe valve are divided into six series: general valve, pipeline valve, slurry special valve, gas special valve, petrochemical special valve and pulverized coal injection valve. There are three kinds of transmission modes: manual, pneumatic and electric. There are eight pressure levels (pn0.25 ~ 10.0MPa) and hundreds of specifications (40 ~ 1000). In petroleum, chemical industry, metallurgy, electric power, gas and other industries, it is the replacement product of gate valve, globe valve, Y-type valve and ball valve. At present, it has been sold well in coal injection in iron and steel industry, slurry, mother liquor and alumina powder transportation in alumina industry, hydraulic (or dry) ash removal in power industry, petrochemical industry, gas industry and other occasions.

The utility model has the advantages of reasonable design, compact structure, small flow resistance, good sealing, light and flexible operation, especially suitable for low-pressure pipe network of water, sewage, steam, pulp and other media. It can be equipped with electric and pneumatic devices, and can realize remote automatic operation. (water, steam, sewage, pulp, mud and other non corrosive media)

It is an ideal equipment for controlling solid transportation such as pulverized coal injection of dust containing gas and particle fluid. It is widely used in various pipeline control of blast furnace pulverized coal injection, pulverizing system and dust removal system in metallurgical, mineral processing and electric power production processes. The sealing pair is made of Co-Cr-W alloy. After special heat treatment, the valve can resist erosion and wear resistance. At the same time, the eccentric spherical surface of the valve has the function of automatic compensation. Through adjusting the bolts on the worm gear, the sealing pair can still achieve the re sealing effect under certain degree of wear. (dusty gas, particulate fluid)

The petrochemical industry uses high pressure, high temperature, full of flammable, explosive, general weak acid and weak alkali corrosive medium, with good sealing, corrosion resistance, light opening and closing, and automatic removal of valve surface scaling. It is suitable for crude oil, heavy oil and other media transportation, oil cracking, food production and other process flow. (oil, gas, gas, water, etc.)

The sealing pair is made of Cr Mn Si cemented carbide. It is fire-resistant, explosion-proof and anti-static. The sealing pair is resistant to high temperature of 560 ℃. Its anti-corrosion and anti seizing capacity are more than 6 times of that of stainless steel sealing pair. It is especially suitable for pipeline transportation and pressure gate station of gas, coke oven gas, water gas, liquefied gas and natural gas. (blast furnace gas, natural gas, dust gas, etc.)

It is the most ideal process valve to transport the solution slurry and slurry ash which are easy to precipitate and crystallize, which can remove the scale obstacles and realize the smooth closing. It has the advantages of high efficiency and energy saving, good wear resistance, reliable sealing, light operation, quick opening and closing, long service life and so on. (transportation of granular materials such as process slurry, slurry ash, etc.)

It is a straight through hemispherical valve without reducing diameter. The valve body channel is connected with the pipe connected by the pipeline into a straight pipe, with equal cross-sectional area and less resistance than the reduced diameter. Full opening and full closing can be achieved only by turning 90 degrees, which is convenient for long-distance pipeline transportation control. (gas and pulverized coal injection).

Special for slurry mixing
