What is DIN3352 F4 resilient seated gate valve?
What is DIN3352 F4 resilient seated gate valve?For a general overview in terms of operation:DIN3352 F4 resilient gate valve (DIN3352F4) consists of two parts:The upper part of DIN3352 F4 consists of 2-pronged pin socket with a rubber gasket (DIN3352F4) or a brass cover (DIN3352F4).
This paper analyzes and studies the gate sealing structure of DIN3352 F4 resilient seated gate valve, and expounds its structural characteristics and practical application. The structure was designed, fabricated and tested for operation in a sealed box and then subjected to a sealed-seal performance test. The DIN3352 F4 was successfully sealed. It shows marked improvement in strength and damping. The DIN3352 can be used as an open-air gate seal unit with proper application of a strong, non-toxic sealant.
DIN3352 F4 resilient seated gate valve comprises a valve body and a valve cover. A channel is arranged in the valve body. A pair of left and right inclined valve seats are arranged in the channel, and a wedge-shaped disc is arranged between the valve seats. The channel is a flexible channel in which the channel body is formed. A central channel is formed in the centre of the dome. The central channel is an inclined channel in which the central channel body is formed. A pair of two-way valve seats and a wedge-shaped disc between the valve seats are arranged in the outlet channel. In the outlet channel, the diameter of the channel is a predetermined specification, preferably a minimum diameters of 16 mm.In contrast to the embodiment of the FIG. 2 of FIG. 4 , there is also a fourth embodiment, of which a preferred embodiment is shown in FIGS. 7A and 7B of the accompanying drawings.
The resilient seated gate valve is equipped with a set of protective device, and a valve box is set on the top of the device. The set of protective device can be inserted through the valve, to selectively control a pressure within the set. The set of protective device includes a valve, an anode and several plates. A gas tube is sealed by means of a seal plug, and a seal can be present on the apertures or channels of the valve. The apertures or channels can be filled with gas, in which case the gas flowing through the valve can enter a gas trap.
Resilient seat gate valve is a new product of ordinary low pressure cast iron gate valve, which is called "green valve", and has been applied in many countries and regions in the world. The advantages of a newly developed product has more than 200,000 sales year. In addition we can offer an excellent performance. For this reason we have an outstanding safety and operating conditions.In other words, this means, a single gate valve and safety system have been applied. As a result, our new gate valve has superior performance characteristics compared to conventional gates. All of this is in addition to the reliability, operating conditions and quality control.
To provide our customers with high quality DIN3352 F4 resilient seated gate valve, exquisite technology, good reputation, conscience building, trustworthy, welcome customers to inquire about products, customers worldwide to be ready in advance more pictures
