The development prospect of the valve cover industry is very good, because it brings many benefits to enterprises when in use, so it is deeply loved by customers. In order to let everyone know more about valve covers, next we will talk about the small knowledge points related to it, hoping to bring help to more people.
Nowadays, many people still do not understand some basic information about valve covers, so as a manufacturer, we also need to briefly explain that, in simple terms, this valve cover is a valve part equipped with a valve stem seal, used to connect or support the actuator. This product can be an integral part of the valve body or separate when in use. In gate valves, the valve cover mainly functions to tighten the packing. According to our understanding, it is often connected to the valve body with high-strength bolts. The valve cover is a part that bears pressure, so the design conditions are the same as those of the valve body. When you are using it, you also need to know that to remove the valve internals, you often need to remove the valve cover first; but some valve structures, such as some common eccentric rotary valves and sliding gate valves, the valve cover is cast together with the valve body at this time. Therefore, in this case, the valve internals can be taken out through the end face of its inlet or outlet flange or through the end face of another separate valve body. Our company is a manufacturer. If you have any needs in this regard, you may wish to come here for an on-site inspection. We have a wide variety of products that can meet the needs of customers in different industries. We guarantee that you will not be disappointed after reading it.
After understanding the basic information of this product in detail about the valve cover, some other knowledge points also need to be mastered. For example, the valve cover has two uses. One is to position the valve stem. With it, the valve stem can be well guaranteed to transmit and switch normally. Another is the sealing function, which also has a certain strength here. At this time, the purpose of the valve cover is to prevent the internal fluid from flowing out. This product has a nameplate with the model of the safety valve on it. The safety valve model has standard and non-standard ones. Generally speaking, the standard one starts with the first letter of the pinyin of '安' of '安全阀'. A ” at the beginning, so everyone should observe this when choosing in the future. Moreover, it is to prevent the medium from flowing out. The valve part equipped with a valve stem seal is mainly used to connect or support the actuator. The valve cover and the valve body can be an integral part or separate. In gate valves, the valve cover mainly functions to tighten the packing. Of course, the two numbers following it represent the connection form and type, followed by a letter representing the sealing surface material, followed by the connection symbol “ - ” and the nominal pressure number and the letter representing the valve body material.
After the introduction of the above content, we have a further understanding of the valve cover. We will not feel strange when we see it again in the future, and problems will not occur frequently during use. Okay, that's all for today's content, I believe it will bring more exciting knowledge points.
