This new practical self-filtering Fully welded ball valve solves the existing problems such as restriction of installation conditions on the setting of filters in the pipeline, the cleaning difficulty during the maintenance, etc. Its reasonable design, compact structure, flexible labor-saving operation, quite convenient installation and maintenance not only obviously reduce the occupied space, but also are good for the cost reduction and wide promotion and application.
Under the opening state of self-filtering fully welded ball valve, when the fluid media passes the inner through-hole cavity of the ball, it can be filtered by the filter network st by its own. When the ball is rotated 90 degrees clockwise, the self-filtering welding ball valve will be in the closing state playing the role of cutting off the fluid media in the transmission pipeline.
On the side wall of the valve body, the connected mid-flange and the drain pipeline connected with the cleaning water pipe are st. It's able to clean the filter network conveniently and quickly by opening the mid-flange cover and the drain pipeline. It can also set an electric valve or pneumatic valve in the drain pipeline in order to realize the self-washing of the filter network. If the filter network is broken, it's able to exchange by opening the mid-flange cover.
In the transmission pipeline of fluid media, the ball valve is an effective and necessary cutoff device. In order to remove the impurities and dirt from the fluid media and keep the transmission pipeline clean and unblocked, a filter set in the transmission pipeline is an essential and important equipment to improve the fluid quality. At the moment, filter and ball valves installed in the transmission pipeline take a large space and are often restricted by application conditions and it's difficult to remove and wash the filter.
Technical Features of self-filtering fully welded ball valve
With the integrated welding structure, there will be no external leakage problem.
The valve seat is constituted by carbonized Teflon seal ring and spring with strong ability to adapt pressure and temperature changes. Within the standard pressure and temperature range, there will be no leakage.
The manufacturing process of the ball is traced and tested by the advanced computer detector. The ball has high manufacturing density.
The seal ring adopts C-PTFE Material with 20% Carbon to guarantee no leakage at all.
Compared with similar products or products of the same specification, the valve body is small and light with a beautiful appearance and long service life.
The valve body, ball and side valve body all adopt seamed steel pipes molded by pressing. At the valve rod, use the double O-Ring for seal with the blow-off resistant function.
The filter network and the ball combine as one. The link of the ball of filter network itself plays a role of filtering in the pipeline and can replace the filter, achieving the effect of one valve with multiple functions. Therefore, it's able to save the installation space of pipeline and the business cost and stop impurities with a diameter of greater than 4.5mm.
The filter network adopts the V-Shaped Port to guarantee the normal pass of media in the case of blocking impurity particle, while the valve can work normally. It adopts the pressure relief valve design which can adjust the internal and external pressure difference of the valve and improve its security performance. Meanwhile, it's able to replace the pressure relief valve with a threaded ball valve to make the operation time-saving, labor-saving, convenient and flexible.
