Vacuum valve manufacturer

The high vacuum flapper valve research and development ability is poor: it can be said that there is no or only a small amount of capital investment, even if it is the so-called new product research and development, it is just a mode of taking orders, designing, and producing, which has caused equipment to some extent The unreliable performance and the immature process have brought hidden dangers to customers. Foreign counterparts have invested a lot of money in research and development, developed key parts and basic parts, and explored and solidified the process. Product or advantage in a certain area.

The sealing performance of the high vacuum flapper valve refers to the ability of each sealing part of the valve to prevent medium leakage. It is an important technical performance index of the valve. There are three sealing parts of the valve: the contact between the opening and closing parts and the two sealing surfaces of the valve seat ; The matching place between the packing and the valve stem and the stuffing box; the connection between the valve body and the bonnet, where the previous leakage is called internal leakage, which is commonly referred to as lax, which will affect the valve's ability to cut off the medium , For cut-off valves, internal leakage is not allowed.

Beipiao Vacuum Equipment Co., Ltd. (formerly Beipiao Vacuum Valve Factory) was established in 1966 and is a designated enterprise of the former Ministry of Machinery and Electronics. The total area of the plant is over 50 acres. The main plant is located in the Taiji Management Zone of Beipiao City. The new plant is located in the Light Textile Industrial Park of the Economic Development Zone of Beipiao City. The total investment exceeds 100 million yuan. There are 62 employees, including 12 engineers and technicians. The company has more than 100 sets of various processing and manufacturing equipment and nearly 20 patented technologies. Over the years, it has been innovating and making progress. It has grown into a professional vacuum acquisition, A high-tech enterprise engaged in vacuum application technology development and equipment manufacturing.

Valves Vacuum valves use electric devices to drive valve stems and ball cores to perform opening and closing actions to connect or cut off the medium flow in the vacuum (pressure) system pipeline. It is used in vacuum, dairy products, wine, biological engineering, and food. In the fields of pharmacy, beverage, cosmetics and chemical industry, when the vacuum valve is delivered from the factory, in order to ensure the elasticity of the packing, it is generally subject to the static pressure test. After the valve is installed in the pipeline, due to temperature and other factors, external leakage may occur. At this time, it is necessary to tighten the nuts on both sides of the packing gland in time.

After the high vacuum flapper valve heats the vacuum valve body, try to open slowly or open it fully and tightly, then close it slightly; loosen the packing gland and try to open; appropriately increase the valve stem clearance; replace the valve stem and nut; Adjust the packing gland bolts; straighten the stem or replace; the vacuum valve stem uses pure graphite powder as the lubricant. Before the vacuum valve rotates the adjusting screw, the inlet pressure of the valve should be reduced to below 0, 9 of the opening pressure. Prevent the valve disc from being driven to rotate when the adjusting screw is rotated, which may damage the sealing surface.

The company is located in Beipiao City, Liaoning Province, in the west of Liaoning Province, with the Bohai Sea in the south and Inner Mongolia in the north. It is an important part of the Bohai Rim Economic Circle. Beipiao City is rich in fossil resources and mineral resources. 44 types of mineral resources have been proven. Among them, gold mineral reserves are very rich, and the fossil industry is prosperous and diverse. It is known as "the world's first bird flying and the first flower blooming." The reputation of "place".

高真空挡板阀技术改造滞后：老厂房、老设备、老工艺仍占主流，虽然近几年几个企业搬迁而有了改观，但整体的制造水平、工艺水平、检测水平仍较落后，与国外同行企业无法相比，旧体制遗留下来的技术改造问题，恐难在短期内予以消除，设备的陈旧、导致工艺的落后和产品水平的低下，这在行业内的每个企业几乎都存在，我国机械真空泵的整体技术并不落后。

The mechanical principle and classification of the high vacuum valve vacuum coating machine: Mechanical pump: also called the backing pump. The mechanical pump is a kind of low vacuum pump that is widely used. It uses oil to maintain the sealing effect and depends on mechanical methods to continuously change The volume of the suction cavity in the pump causes the volume of the gas in the pumped container to continuously expand to obtain a vacuum. Classification of mechanical pumps: There are many types of mechanical pumps. Commonly used are slide valve type (mainly used for large equipment) and piston reciprocating type. , Fixed vane type and rotary vane type (this is currently widely used) vacuum valves.

The transportation in Beipiao City is very convenient. The Beijing-Shenzhen high-speed railway can directly connect to Beijing, Shenyang and other cities. National highways 101 and 305 and Changshen Expressway run through urban and rural areas. The central city is 45 kilometers away from Chaoyang Airport and 150 kilometers away from Jinzhou Port.
