Product Description

Eccentric semi-ball Valve

1. Purpose and performance specifications

1.1 Purpose:This product is suitable for waste water treatment, pulp, alumina, city heating heating was required. Apply to power plant, the control of hydraulic slag or gas pipelines. Can realize to adjust the medium and carefully cut off.

1.2 Scope of application: water treatment, pulp, alumina, city heating heating, power plants, hydraulic slag or gas pipelines, etc.

1.3 performance specifications

1.4 Adoption standard
The design and manufacture according to stipulations GB12237, API608;
Inspection and testing according to the provisions of the API 598;
The provisions of the regulation according to JB79 or GB/T9113.1 flange size;
The face to face size according to stipulations GB12221;
According to stipulations GB9131 pressure - temperature.

2. Structure characteristic and using principle

2.1 See diagram structure and the main dimension

2.2 This product by the body, the eccentric shaft, valve cover, spherical cap, bushings, valve seat main parts, such as by eccentric shaft rotate 90 ° of the valve opening and closing, have the effect of truncation medium.

2.3 This product to ensure the valve in the process of opening or closing, seat and spherical cap without rubbing against each other, this product USES the eccentric crankshaft, making the center line of the spherical cap deviates from the center line of the valve port a eccentricity. When the valve opens, the crankshaft turns a small Angle, the ball will leave the seat, the ball and seat no longer contact; On the other hand, in the process of valve closing, only in the closing moments, spherical cap and seat contact.

2.4 This product USES jacket type structure, in the process of maintenance, do not need to be removed from the pipeline, simply remove bonnet bolts on, remove the valve cover, which can remove the eccentric shaft, so to ensure the valve to online service.

2.5 Characteristic

For the jacket type structure. The valve can be directly mounted on the pipeline online inspection and maintenance, can effectively reduce the parking device, reduce the cost.

Single seat design. To eliminate the influence due to abnormal pressure valve lumen medium use safety problems.

Low torque design. Special structure design of the valve stem, only with a small hand could easily open/close the valve.

Open/close without friction. This function completely solve the traditional valve for sealing surface friction each other and affect the sealing problem.

The structure of sealing wedge. Valve by valve stem provides mechanical force, wedge pressure the ball into the seat and seal, make the valve's sealing is not affected by changes in the pipeline pressure difference, under various conditions sealed performance has a reliable guarantee.

Since the clean structure of the sealing surface. When the ball tilting away from the seat, fluid in the pipeline along the sphere uniform sealing surface into 360 °through, not only eliminates the high velocity on the seat of local scour, also washed away by the accumulated on the surface of the sealing material, achieve the goal of the clean.
