Product Description
The production introduction
Fixed Electric Flanged Ball ValveQ947 fixed electric ball valve is suitable for two cutting, adjusting occasions. The valve and the actuator are connected by direct connection. The electric actuator has a built-in servo system without additional servo amplifier. The input of 4-20MA signal and 220VAC power supply can control the operation. It has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action, etc. The actuator can be configured with UNIC, PSQ, HQ, DHL and other models of electronic electric actuator or GTX, AL and other gas piston actuator according to user requirements.Execution standard1. Design and manufacture: GB12237-89, API608, API 6D, JPI 7S-48, BS5351, DIN3357.
2. Flange dimensions: JB/ T74-90 (JB74-90), GB9112-9131, HGJ44-76, SH3406, ANSI B16.5, JIS B2212-2214, NF E29-211, DIN2543.

4. Inspection main test: JB/T 9092, API 598.Product featuresQ47 fixed ball valve is a new generation of high performance ball valve, suitable for long-distance transmission pipelines and general industrial pipelines, its strength, safety, resistance to harsh environment, etc. in the design of special consideration, suitable for all kinds of corrosive and non-corrosive media. Compared with the floating ball valve, it works, the fluid pressure in front of the sphere of all is passed to the bearing force, will not make a sphere to the seat to move, so the seat will not bear too much pressure, so the fixed ball valve torque is small, the seat of the small deformation, stable sealing performance, long service life, applicable to high pressure, large diameter. Advanced spring pre-seat assembly with self-tightening characteristics for upstream sealing. Each valve has two seats and can be sealed in each direction, so installation is two-way with no flow restriction.
The valve has two and three pieces of two body structure, the flange is connected with bolts, sealed with enhanced PTFE inserted into the stainless steel ring, ring back without spring to ensure that the seat close to the ball, keep sealed. There are no PTFE bearings on the upper and lower stem to reduce friction and save labor in operation. There is no adjusting plate at the bottom of the small shaft to ensure the joint position of the ball and the sealing ring.
Full size: valve flow aperture to line id for line cleaning
1. Labor-saving operation: the ball is supported by upper and lower bearings to reduce friction and eliminate the excessive torque caused by the huge sealing load formed by the ball and the sealing seat driven by the inlet pressure.
2. Reliable sealing performance (see Figure 1) : PTFE single material sealing ring embedded in the stainless steel seat, metal seat tail is provided with a spring to ensure that the sealing ring enough pre-tightening force, the valve in the use of sealing surface wear, under the action of the spring valve to ensure good sealing performance.
3. The fireproof structure (see figure 2) : to prevent because of heat or fire, make ptfe sealing ring burned, larger leakage occurs, and feeds the fire, set fire prevention sealing ring between the sphere and valve seat, burned down in sealing ring, in under the action of spring force, will seat ring is rapidly to the sphere, form the metal to metal seal, have a certain degree of sealing effect. Fire resistance test conforms to APl 6FA and APl 607 standard.
4. Automatic pressure relief function (see Figure 3) : when the medium pressure of stagnation in the valve chamber rises abnormally and exceeds the preload force of the spring, the seat will retreat from the ball to achieve the effect of automatic pressure relief, and the seat will automatically reset after pressure relief.
5. Discharge pipeline: the upper and lower parts of the valve body are installed with discharge hole L, so that the valve seat can be checked for leakage. In the work, when the valve is fully open or fully closed, the pressure in the middle chamber can be removed and the packing can be directly replaced. It can discharge the residue in the cavity and reduce the pollution of the medium to the valve. Auxiliary seal setting system (please specify when ordering)
6. See Figure 4: The valve is designed with an auxiliary valve seat emergency sealing system. Once the seal is damaged or cannot be sealed due to emergency conditions, the sealing surface can be repaired by injecting corresponding sealant into the sealing surface through the auxiliary sealing system to achieve emergency sealing. When the conveying medium is unclean or contains a small amount of particles, in order to protect the sealing surface and ensure a reliable seal, the device can also be injected with the corresponding cleaning agent or lubricant to clean the sealing surface.
7. Widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, papermaking and other transmission pipeline medium cut off or circulation. The sealing surface can also be cleaned by injecting the corresponding cleaning agent or lubricant into the device.Technical parameters and performanceTest pressure (Mpa) | Nominal pressure(Mpa) | Class | JIS(Mpa) |

GQ947 electric track ball valve
GQ947Y electric track ball valve is a new practical product, with a rotating ball core 90 degree pendulum cut off a high-tech ball valve. Domestic currently Q type ball valves are used in a given pre-tightening force under the ball and seat friction for open and close, often leads to the sealing surface damage, the valve leakage and the phenomenon of death, track ball valve is the updated design for the common defects make the ball core rotate 90 degrees to switch is a new type of ball valve, the ball valve can make the sealing surface, no friction, achieve the aim of safety without leakage, And greatly improves the service life of the valve.Structure Feature
Traditional ball valve, whether floating or fixed, ball and seat always contact, large switching torque, sealing surface easy damage, orbit ball wheel open and close, the ball deflected -δ Angle, and then rotate, the whole process of the switch ball and seat from, so the seat will not be bruised, and small opening and closing torque.Main parts and materialsPart name | Material |
