进口全金属硬密封套筒阀美国阿卡迪亚品牌

进口全金属硬密封套筒阀Product Description:

The utility model comprises an upper valve body, a lower valve body, a valve rod, a balance cylinder, a valve seat, a sleeve, an integral sealing valve core, a white steel clip graphite winding gasket, a pressure bearing concave ring, an integral sealing ring and an elastic guide ring. The utility model is characterized in that the pressure bearing concave ring, the integral sealing ring and the elastic guide ring belong to a part of the integral sealing valve core, the section of the integral sealing ring is an open ring sheet with an arc shape, and the integral sealing ring is close to the inner wall of the balance cylinder, The pressure bearing concave ring at the front end of the integral seal ring is provided with a structural groove in the middle. An elastic guide ring is designed at the lower edge of the groove. The ring wall is in contact with the inner wall of the balance cylinder. Six balance holes are evenly distributed on the integral seal valve core. Compared with the prior art, the beneficial effects are: simple structure, convenient use and strong applicability. The integral seal ring changes with the change of medium pressure. It can be used in occasions with high pressure difference. It is easier to realize sealing by adopting the integral seal structure, It is used in high temperature environment, and the all metal hard seal has long service life

进口全金属硬密封套筒阀characteristic:

The valve core of the balanced sleeve regulating valve adopts a fixed structure, which can balance the internal pressure of the valve only by offsetting the pressure difference of the medium communication itself. This balance can not completely offset the pressure difference of the medium. There is still an unbalanced force between the valve core and the valve stem, which is prone to leakage. In addition, the sealing of the regulating valve is usually sealed in the form of sealing ring or external sealing device. The sealing ring is made of non-metallic material, which has certain shaping and elasticity, The texture is soft, the service temperature usually cannot be higher than 220, and the circulating medium cannot contain impurities, otherwise it is easy to wear. Although the external sealing device solves the problem of high temperature, it has large friction resistance and is easy to deform after long-term use, resulting in valve sealing failure, which is not conducive to frequent use for a long time and short service life.

进口全金属硬密封套筒阀Principle:

The all metal hard sealing sleeve valve comprises an upper valve body, a lower valve body, a valve rod, a balance cylinder, a valve seat, a sleeve, an integral sealing valve core, a white steel clip graphite winding gasket, a pressure bearing concave ring, an integral sealing ring and an elastic guide ring. The upper valve body, the balance cylinder and the lower valve body are fixed with each other. The valve seat and the sleeve are installed at the medium outlet inside the lower valve body. It is characterized in that the integral sealing valve core is a lower extended sleeve structure, The upper part has its own sealing structure. There is a matching internal thread hole in the middle of the integral sealing valve core. The valve rod is matched and connected with the integral sealing valve core through the internal thread hole. The outer wall of the integral sealing valve core is matched and contacted with the inner wall of the balance cylinder. The pressure bearing concave ring, integral sealing ring and elastic guide ring belong to a part of the integral sealing valve core. The section of the integral sealing ring is an open ring sheet with arc shape, and the outer diameter of the integral sealing ring is larger than the inner diameter of the balance cylinder, After assembly, the integral seal ring is close to the inner wall of the balance cylinder. There is a circular pressure bearing concave ring at the front end of the opening of the integral seal ring. There is a structural groove in the middle of the integral seal valve core. A semi ring elastic guide ring is designed under the groove. The ring wall of the elastic guide ring contacts and fits with the inner wall of the balance cylinder. The lower end of the integral seal valve core fits and seals with the valve seat and sleeve. Six balance holes are evenly distributed on the integral seal valve core.
