7. Unattended, no external signal control valve work. Hydraulic damping slow-closing device is an independent system, can be adjusted according to working conditions, without oil or power to control it, no maintenance, environmental protection and energy saving, lower operating costs
8. Swashplate type three eccentric hard seal check valve is suitable for horizontal or vertical installation on the pipeline.
Structure
The three-eccentric hard-seal check valve of the energy-saving type adopts a three eccentric structure, and consists of a valve body, a valve disc, a valve shaft, a valve seat and a damping mechanism.
The valve body consists of two parts. Two parts of the body in the flange, the body of the valve plate, valve seat tilt arrangement, and the body flow channel centerline angle of 55 °. The cavity surface area is greater than the valve body diameter area 40%, the entire valve flow resistance coefficient is small.
Seat and runner center line at a certain angle. Seal surface of the valve seat is part of the oblique cone, and the sealing line formed between the valve seat and the valve disc is an approximate elliptic curve. The angle between the plane of the elliptical sealing line and the centerline of the valve flow channel is 55 degrees ; The approximate ellipse seal line center of the long axis and the cone axis to form an angle of eccentricity, namely the valve seat sealing surface in the cone axis and the valve body flow channel center line formed between the angle (β) 10 ~ 15 ° , The axis of the rotary axis of the valve disc is eccentric with respect to the axis of the cone and forms an eccentricity (E1), and is also eccentric with respect to the plane of the sealing line.
The valve disc is butterfly disc type valve disc, streamline structure design. When the media pressure reaches its working pressure, the valve automatically opens; when the media pressure decreases, the butterfly-shaped valve disc automatically closed.
The valve shaft is a two-stage structure, with self-lubricating bushings, flexible rotation, opening and closing effort.
Unique damping mechanism mainly by the fuel tank, springs, buffer rod, piston and needle valve components. When the valve disc is closed to the last 5 °, the buffer bar to slowly close the valve plate, the valve seat to achieve non-impact, non-collision and no noise to close the seal.
working principle
Technical performance
1. Energy conservation
Energy saving: This tilting disc check valve has the characteristics of energy-saving operation, it is slow closing, wear-resistant, no leakage and the characteristics of a variety of applications can be competent harsh working conditions. Because it has the lowest pressure loss characteristics in any of today's check valve types. Ultra-low head loss is achieved by streamlined valve body design, hydrodynamic design of the valve, the valve cavity is greater than the nominal diameter of 40% of the flow area to achieve. Energy saving is achieved through the application of a 55 ° inclined disc check valve instead of the traditional 90 ° swing check valve to reduce the opening and closing stroke to achieve the purpose of saving energy costs and reduce the use of the valve cost.
Slow Closing: The sloping valve flap is characterized by the use of a short valve stroke, a unique valve reaction, and a fixed shaft pin without a stem packing. First, the traditional swing check valve has 80 ° ~ 90 ° stroke, this tilt valve is only 40 ° stroke, through this tilt angle of the valve seat design to achieve a shorter valve stroke. It is evident that the short stroke reduces the closing time of the valve flap and reduces the return time and the water hammer impact due to the return flow. Second, the valve is the reaction of the eccentric shaft to the valve is divided into about 1/3 or 2/3 position, the shaft through the 1/3 flow reaction under the axis of the 2/3 flow, the anti-use through the buffer itself Reducing the impact of the valve flap, while the traditional swing check valve does not have this feature. Finally, the traditional swing check valve is a rotary valve stem with packing, while the inclined seat check valve without packing, the valve can be free to rotate around the shaft, reducing friction and accelerate the closure of the valve.
2, high-performance
Leak-tight sealing: Leak-tight sealing is achieved by using a 20 ° sealing angle. The 20 ° sealing angle has excellent conical sealing performance and is free of binding and automatic release characteristics. A small amount of valve shaft clearance allows the valve to be sealed against the valve seat without interference from the valve shaft.
Long-life stability: eccentric valve shaft can make the valve in the case of non-sliding and shackled tilt out of the seat, a unique tilt to reduce the valve seat and valve wear, the valve life extension. Hydrodynamic design of the valve flap, both in high flow or low flow medium case, the fluid resistance is very small, can guarantee excellent stability and reduce the vibration of the valve flap wear.
3. Applications
Oblique seat check valve is our company's best products in the check valve, it has an unparalleled variety of applications and reliability, can greatly reduce the cost of using the valve. This valve can be used in any installation layout.
In single-pump systems, swash-plate check valves are commonly used in centrifugal and turbo pumps with flow rates of 4-20 ft / s and pressures up to 400 PSI.
In a multi-pump system, the system is set to reduce jitter and improve the system's ability to better apply the valve. The accurate positioning of the limit stop prevents the valve flap from vibrating, regardless of high flow rate or low flow rate, ensuring extremely low head loss characteristics. When the system shuts down, the multi-pump or parallel pump can produce rapid return flow, the flow rate can be constant. Swash-type triple-eccentric hard-seal check valves are equipped with optional hydraulic snubbers on the upper or bottom to help shut the disc in a multi-pump system even in the event of a power failure.

10. Set butterfly valve, check valve features in one, plus a unique hydraulic slow closing system, the performance significantly.
working principle
1.Open the valve
Start the pump, the valve before the media pressure increases to the set value, the media acting on the force of the valve plate will slowly open to full-open position, the set value and the size of the hammer arm.
When the valve is opened, the hydraulic oil in the cylinder flows through the check valve from the needle valve, avoiding the pressure of the cylinder, so that the valve can be opened flexibly. Valve slow closing device has a limit device to ensure that the valve plate will not open over.
2.shut down valve
When the media pressure before the valve suddenly decreases, the valve plate in the media back and under the action of heavy hammer closed.
Valve closing process using two stages of buffer: 90 ° ~ 15 ° range, the hydraulic oil through the throttle hole through the needle valve, needle valve to adjust the fixed throttling, slow down the valve closing speed, this time the valve is fast closing process; In the 15 ° ~ 0 °, the hydraulic oil flow through the throttle valve, throttling throttle through the throttle to stepless adjustment, this time the valve is a slow off process, from the surface to slow closing effect.
3.adjust
Switch and slow closing time can be adjusted according to the scene, so that the valve is in the best working condition.
Adjust the hydraulic cylinder needle valve, you can adjust the valve opening and closing speed and time.
Adjust the throttle valve on the hydraulic cylinder, you can adjust the valve phase slow closing speed and time.
