How to distinguish single gate and double gate valve

Gate valve plate Several forms of gate valve according to the structure of the gate is divided into two types of wedge and parallel. Wedge gate has three kinds of structure: Single gate structure (Figure 1) is relatively simple, but the wedge angle machining accuracy requirements are high, prone to clamping, abrasion phenomenon; double gate (Figure 2a) Wedge angle less demanding, the gate wedge is not easy to die, but the structure is more complex; elastic gate (Figure 2b) combines the advantages of single and double gate, to avoid their shortcomings, and thus more widely used. Its structural feature is the presence of an annular groove in the periphery of the gate, so that the gate has the appropriate flexibility. Parallel gate valve is usually double gate structure (Figure 2c); special purpose gate valve, such as long-distance oil transmission, gas pipeline with large-diameter gate valve for cleaning and the need for a single gate structure. How to distinguish between single-gate and dual-gate valve valve models can distinguish, such as: Z41Y-16, DN150 is a single gate flange valve, nominal diameter 150, the sealing surface material is carbide. The Z42-16, DN150 is a double gate valve, the other parameters are exactly the same. Judging from the appearance of crude judgment, double gate valve seal protruding part is greater than a single gate. How to distinguish single-gate and double-gate valve Single-gate valve is the most common, the price is lower, the technology is mature, reliable sealing Keywords: gate valve

Injection Molding

Plastic Injection Molding Factory.We are advanced China Plastic Injection Molding manufacturers. Our Plastic Injection Molding manufacturing methods are extremely accurate and fast. They can provide unlimited rapid prototype plastic injection molding capabilities for a wide variety of high-volume products. The method is also used for low volume, high-quality plastic parts for everything from toy cars to giant television screens. Rapid prototyping is the process of designing and creating a new product or component using plastic injection molds. It is a critical process because it helps identify new product characteristics by testing them over again before a product goes to production.Plastic injection molds allow designers and engineers to create detailed models from digital designs that can then be brought to life into a physical product. This kind of design sharing provides a tremendous advantage for companies trying to reduce product development costs.
Many rapid injection molding tools include tools that are designed to assist the manufacturer with their overall production efforts. These tools can offer you a number of additional services including computer software designed to help you streamline your production efforts and increase your profitability. By streamlining your efforts, you can expect to see a significant increase in your production rate and efficiency.
RongNa offer OEM/ODM custom rapid prototype plastic injection tooling which can help you reduce the time necessary to create new parts and can save you valuable money on material costs.
