Which high vacuum baffle valve is suitable

Installation and application of high vacuum flapper valve vacuum valve 1. The vacuum valve should be equipped with a filter to prevent impurities in the medium from entering the pressure reducing valve and affecting its performance. 2. It is necessary to flush the pipeline system before installing the vacuum valve. Organize to prevent welding slag, oxide skin and other dirt from flowing into the valve, affecting the normal operation of the valve. 3. There should be a straight pipe before and after the pressure reducing valve of the device. The length of the straight pipe before the valve is about 600 mm, and the length of the straight pipe behind the valve. About 1000 mm, the vacuum valve should be installed in a place that is convenient for operation and repair.

If the high vacuum flapper valve is classified according to the working pressure of the actual starting system, there can be rough vacuum system, low vacuum system, high vacuum system, ultra-high vacuum system and extremely high vacuum system. If it is divided according to the cleanness of the vacuum system, it will There are oil vacuum systems and oil-free vacuum systems. Due to people’s habits, the above-mentioned different categories are often combined in practical applications, such as "large dynamic metal high vacuum systems", "oil-free ultra-high vacuum systems", etc. , The above classification method is not strictly unchanged.

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 valve learns the content of cold and frost protection. In autumn, all kinds of vacuum valves must be inspected. Vacuum valves check the cold and frost protection of the pipeline. The frost protection must be divided into regions. The difference between the north and the south is not small, and the characteristics of winter should be combined In practice, the unit has formulated anti-freezing measures for boilers, pressure vessels, pressure pipes and their auxiliary valves, and relief devices in winter, and implemented the measures in real places; increased daily inspections of parts that are prone to freeze cracks, and vacuum valves use insulation materials Strengthen the insulation of the device.

The vacuum valve is equipped with a pre-vacuum pipeline valve (called low vacuum valve) on the pre-vacuum pipeline. The high-vacuum valve on the main pump usually cannot be in a vacuum state under the valve cover, and the valve cover is opened under atmospheric pressure. This must be passed Electrical interlocking ensures safety. Foreline valve and pre-vacuum pipeline valve should be considered to be able to open the valve at atmospheric pressure. For vacuum system with steam flow pump as the main pump, the main valve should cover the main pump and foreline valve. Also cover the main pump and the valve cover of the pre-vacuum pipeline to the vacuum chamber.

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.

Which high vacuum baffle valve is suitable

High vacuum valve Electromagnetic vacuum belt charging valve and electromagnetic vacuum differential pressure valve are vacuum valves specially used to prevent oil from returning to mechanical vacuum pumps. They are installed at the inlet of mechanical vacuum pumps and open and close synchronously with the pump. Generally, they cannot be used elsewhere , Which means that it cannot be used for deflation in a vacuum system. The advantage of choosing Nivel electromagnetic vacuum differential pressure valve is that it consumes very little power and saves energy; the valve body with DN≤50 is made of aluminum alloy, which is light in weight. Small size, fast closing speed of valve plate.

The trapezoidal thread of the valve stem and stem nut of the high vacuum flapper valve is worn and the packing is out of date and invalid. If damaged, it should be replaced in time. After the valve is overhauled and installed, the sealing function test should be carried out. The vacuum valve should be carefully disassembled and assembled Valve packaging, check the labels or signs against the list of materials, specifications and schedules to ensure that they meet the requirements of the order and working conditions, pay attention to the special warning labels or signs attached to the valve or accompanying the valve, and take appropriate Measures, check the valve to indicate the sign of the flow direction.
