New technology family health meter unveiled
Gate Valve , one of the most widely applied valves, is a valve that opens by lifting a gate/wedge out of the path of the fluid. The gate faces of gate valve could be a wedge shape or be parallel. Gate valves are not suitable for regulating flow, having been designed to be fully opened or closed. When fully open, the gate valve has no obstruction in the flow path, resulting in very high flow coefficient.
Gate valves have either a rising stem or a non-rising stem. Rising stem provide a visual indication of valve position. Non-rising stem is used where vertical space is limited or underground.
Kolink gate valves are supplied with three basic type of body-bonnet closures: bolted bonnet, welded bonnet and pressure seal bonnet. Bolted bonnet, the seal depends on the body-bonnet bolt preload to maintain sufficient compressive force, bolted bonnet is widely used for valves on various pressure ratings and sizes. Welded bonnet is mainly applied for small-size forged steel gate valves, suitable for applications requiring zero leakage on body-bonnet joint when carrying hazardous system fluids. Pressure seal bonnet is adopted for valves for high pressure service, typically in excess of 15 MPa (2250 psi). The body-bonnet joint seals improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-bonnet joint.
Kolink gate valves are with flanged ends, butt weld ends, socket weld ends and screwed ends, and are constructed with various materials of cast carbon steel, stainless steel, alloy steels, and forged steels.
Various combinations of seating and stem materials are available to meet specific customer requirements.
The Cross-section of a Typical Cast Steel Gate Valve:
1) Austenitic ductile iron stem nut provides resistance to wear and heat.
4) Spacer rings and double packing sets available upon request.
8) Flexible wedge compensates for seat face distortion and body deformation due to pipe stress.

The new technology is not a period of innovation, the sky is full of high-tech eyes, and now these people are really unpredictable, new technology products will be produced every moment. The reporter reported that the 12th China Information Technology Expo jointly sponsored by the Tianjin Municipal Government was held at the Meijiang Exhibition Center. The reporter also saw at the scene that the fairs displayed some new technologies. You can also experience new listings of new technologies while you are watching live. In Tianjin, a signing ceremony for investment projects in the electronic information industry was also held. A number of projects have been signed with companies such as Guangdong Nuclear Power Group Corporation and the number of investments reached 20.6 billion. In the exhibition center, the reporter also gave a key experience to the health apparatus.
The Huawei Family Health Monitor allows the patient to easily complete the electrocardiogram at home, as well as seven measurements such as blood oxygen saturation and sleep monitoring. The health monitor is one of the health care devices. Take a look at the word of mouth and sales status of the family health meter.
Due to the variety of home medical products. The new features of the customer's recognition of these brands also do not quite understand the need to further experience a lot, but also look at its sales channels and marketing methods. This is important. If you don't do these channels with a good product, then these products are still worthless. How can customers not improve the customer satisfaction and product dependence? In order to fundamentally improve the success rate of marketing, the product sells more naturally the customer will know the benefits of this product.
Look at how easy it is for customers to experience this product. If you are lying in bed, you can do a full inspection. Why not? This home health device can be treated whether it is for men, women or children.

2) Rising stem with precision trapezoidal threads for long-lasting service.
3) Two piece self-aligning Gland Bushing and Gland flange prevent stem damage.
5) Machined backseat designed to relieve back pressure on the stem packing when fully seated. Replacing stem packing under pressure is not recommended.
6) Renewable welded-in or screwed-in seats provide a bubble tight joint.
7) Wedge disc fully guided and precision fitted to ensure tight sealing performance.
