Fixed cone valve customized by Jinbin Valve
Fixed cone valve product introduction for Sadawarna project:
The fixed cone valve is composed of buried pipe, valve body, sleeve, electric device, screw rod and connecting rod. Its structure is in the form of outer sleeve, that is, the valve body is fixed. The cone valve is a self balancing sleeve gate valve disc. The hydraulic force will not directly act on the disc. The driving force is very small and has energy-saving effect; The seal adopts metal to metal, special stainless steel valve seat, and the leakage is very small. Chongqing conical valve drives the rocker arm to rotate by means of manual turbine, electric or hydraulic, and then drives the sleeve brake to move in a straight line through the slider to open and close or throttle the valve.
Fixed cone valve product features:
1. Good hydraulic conditions, with higher flow coefficient u = 0.75 ~ 0.86 or higher than other valves;
2. Simple structure and light weight; All transmission parts are set outside the valve body, which is clear at a glance and convenient for maintenance and repair;
3. With small opening and closing force and light operation, it can be applied to small and medium-sized hydraulic engineering sites without power supply. Electric, pneumatic and hydraulic opening and closing mechanisms can be set to easily realize remote control or unattended automatic operation;
4. During discharge, the jet tongue is horn shaped, diffused and aerated in the air, with good energy dissipation effect. It is simple to use energy dissipation pool or do not need energy dissipation measures. If it is set as submerged outflow, the underwater energy dissipation is also very simple;
5. The fluid is evenly divided through the internal 4 guide wing without vortex and vibration;
6. The opening and closing or flow control of the valve is controlled by the up and down movement of the external sleeve to drive the action of the conical valve core. The guide ring and O-ring are used to guide and seal between the sleeve and the valve body, so that the flow coefficient of the valve has a certain proportional relationship with the valve opening.
7. Metal hard seal and fluoroplastic soft seal can be set for fluid media with different conditions and pressures. The composite seal structure designed with high-strength alloy stainless steel wear-resistant valve seat has the characteristics of metal to metal hard seal and soft seal;
8. The divergence angle can be limited to decompose the fluid into thin spray form or annular convection to achieve the purpose of impact offset. At the same time, it can meet the needs of different sites.
9. According to the angle between the horizontal line of the valve and the central axis, 180 ° horizontal installation is common. In addition, 45 °, 60 ° and 90 ° are adopted.
Jinbin valve can customize the cone valve according to customer requirements. Jinbin has completed the cone valve for Mekong River power station. According to the requirements and working conditions of customers, the cone valve produced by Jinbin has also successfully completed the test run.
