Which high vacuum valve is affordable

Vacuum valve When the vacuum valve leaks, attention should be paid to the location and cause of the leakage. There are two common types: duty leakage and external leakage. External leakage is divided into packing leakage and valve cover, valve body leakage and sealing surface according to its external structure. Or the fabric material leaks, the operator should judge that if he can solve it, he should deal with it in time, and the maintenance worker should deal with it in time. The electromagnetic vacuum belt inflation valve and electromagnetic vacuum pressure difference valve are specially used to prevent the vacuum of the mechanical vacuum pump from returning oil. The valve is installed at the air inlet of the mechanical vacuum pump and opens and closes synchronously with the pump.

High vacuum valve Vacuum valve refers to the vacuum system component used to change the direction of air flow, adjust the size of air flow, and cut off or connect the pipeline in the vacuum system. The closing part of the vacuum valve is sealed with a rubber sealing ring or a metal sealing ring. , The bellows of the bellows globe valve is made of stainless steel, high-zinc brass JI80, plastic and other materials. The closing parts of the globe valve with a small diameter (caliber below 10 mm) can be sealed with a diaphragm, low vacuum and medium A spherical plug valve can be used for vacuum.

Beipiao Vacuum Equipment Co., Ltd. has a technical team with rich practical experience and specializing in the research and development of vacuum equipment. Over the years, through the continuous exploration and innovation of several generations of Beipiao people, the company can design and manufacture high vacuum oil diffusion pumps. , Oil diffusion jet vacuum pumps, various series of vacuum valves and vacuum units, etc., including more than 20 series of vacuum application equipment, more than 100 varieties of products.

The high-vacuum flapper valve can also use a nut with an inner diameter more than twice the leakage point to let the leakage medium flow out of the nut when the medium pressure is low at the valve body leakage of the vacuum valve and the leakage is small. The nut is welded to the valve body, and a bolt of the same specification as the nut is fitted. A rubber pad or asbestos pad is placed at the bottom of the nut, and the top of the bolt is screwed into the nut with raw tape to prevent leakage. Vacuum valve However, for the vacuum valve body with high leakage medium pressure and large leakage, drainage welding is required.

High vacuum baffle valve gate valve should not be inverted, otherwise, the medium will stay in the valve cavity for a long time, which will easily corrode the valve stem. Rising stem gate valve should not be installed underneath to prevent the wheel rod from rusting. When installing or replacing heavier gates , Lifting locks cannot be tied to the handwheel or valve stem, but should be tied to the valve body to avoid damage to the handwheel or valve stem and other parts. The check valve has two types: lift check valve and swing check valve. It can only be installed horizontally. The swing check valve must be installed horizontally with its shaft pin. The swing check valve can be used on horizontal and vertical pipelines.

Since its transformation in 2000, Beipiao Vacuum Equipment Co., Ltd. has injected new vitality and vitality into the enterprise. It has successively developed large-caliber and special-shaped electric and pneumatic high-vacuum flapper valves. It has also developed rapid development for national defense and scientific research departments. Closed high-temperature water-cooled large flapper valve has become a domestic manufacturer of oversized valves.

High vacuum baffle valve vacuum valve often neglects the pressure problem during grease injection. During the grease injection operation, the grease injection pressure changes regularly, the pressure is too low, the seal leaks or the failure pressure is too high, and the grease injection port is blocked. If the grease is hardened or the sealing ring is locked with the valve ball and valve plate, and the grease injection pressure is too high, check the grease nozzle on the one hand, if the grease hole is blocked, replace it; on the other hand, the fat is hardened. Clean fluid, seal grease that has repeatedly failed, and inject new grease to replace it.

The technological transformation of high vacuum flapper valve is lagging behind: old factories, old equipment, and old technology still dominate the mainstream. Although several companies have moved in recent years and have improved, the overall manufacturing level, technology level, and testing level are still lagging behind. Foreign peer companies cannot be compared. The technical transformation problems left over from the old system may be difficult to eliminate in the short term. The obsolete equipment, the backward technology and the low product level, exist in almost every company in the industry. The overall technology of China's mechanical vacuum pump is not backward.
