Abstract
The utility model relates to a double ceramic chip driving-fit valve, which is characterized in that a valve core is a pair of round ceramic chips, a lower ceramic chip is parallel to the axis of a valve body and fixedly embedded in the cavity of the valve body, and a connecting groove on the external surface of an upper ceramic chip is connected with a valve rod; the contact surfaces of the two ceramic chips are polished faying surfaces, two scallop holes are correspondingly formed on each of the ceramic chips, a small round groove is formed at the circle center of each of two corresponding surfaces of the ceramic chips, a small positioning shaft is arranged in each small round groove, the connecting groove on the external surface of the upper ceramic chip is a strip-shaped groove, and a strip-shaped clamp board is arranged at the bottom of the valve rod and matched with the upper ceramic chip; and a fluid flows from the scallop holes of the upper ceramic chip to the scallop holes of the lower ceramic chip. The driving-fit valve has the advantages of simple structure, convenient operation and low cost, and the valve core made of industrial ceramics avoids being seized by rust if not used and can change along with the pressure.
Description
Technical field
The utility model relates to a kind of industry and civilian valve.
Background technique
Valve industry and civilian in extensive use, though specifications and models are varied, material-structure also is not quite similar, and purposes is to control fluid, the ball valve that uses in the present technology, gate valve, stop valve etc., their common problems that exists are: be prone to tight interior leakage of seal spool, leak outside poorly sealed leakage between valve gap and the valve body between valve rod and the valve gap, ubiquity is short working life, to the material requirements height, operating difficulties, problem such as not wear-resisting.
Summary of the invention
The purpose of this utility model is: design a kind of two-ceramic plate driving fit valve, to overcome the tight interior problem of leaking of seal spool in the above-mentioned prior art.
Realize that the technological scheme that the utility model purpose is taked is: spool is one group of circular ceramics, and lower porcelain slice and valve axis secured in parallel are embedded in the valve body cavity, and upper porcelain slice is connected with valve rod; The surface of contact of two ceramics is the polishing closed surface, is equipped with the fan shaped borehole of two correspondences on each ceramics, makes 90 degree directions and changes, and finishes opening and closing of spool; Circle centre position in the corresponding one side of two ceramics has a small circular groove respectively, is placed with a little positioning rotating shaft in groove, and the length of little positioning rotating shaft is slightly less than two small circular depth of groove sums.
Fan shaped borehole area on each ceramics is not more than 50% of each ceramics gross area.
The valve rod connecting groove of a long strip is arranged on the upper porcelain slice outside, and the rectangular clamp of valve rod lower end matches with the valve rod connecting groove.
Valve body inner fluid flow direction is designed to, from top inflow, from following outflow.
Good effect of the present utility model is: simple in structure, to operate lightly, and cost is low, and spool adopts industrial ceramics to make, and has avoided for a long time that time spent spool rust is dead, can be with change in pressure; Because fluid is from top inflow, from following outflow, thus not only be subjected to the pressure of valve rod spring on the upper porcelain slice in the valve chamber, but also be subjected to the pressure of pipeline inner fluid, so sealing effect is better.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model; Accompanying drawing 2 is a schematic representation below the upper porcelain slice; Accompanying drawing 3 is a schematic representation above the lower porcelain slice.
Embodiment
The utility model as shown in Figure 1, this valve is made up of valve body 3, valve gap 2, spool, valve rod 1, spool is one group of circular ceramics, lower porcelain slice 6 is embedded in valve body 3 cavitys with the valve axis secured in parallel, upper porcelain slice 4 is connected with valve rod 1; The surface of contact of two ceramics 4,6 is the polishing closed surface, is equipped with the fan shaped borehole 8,11 of two correspondences on each ceramics 4,6, and fan shaped borehole 8,11 areas on each ceramics 4,6 are not more than 50% of each ceramics gross area.Upper porcelain slice 4 revolved turn 90 degrees, finish opening and closing of spool; Circle centre position in two ceramics, 4,6 corresponding one sides has a small circular groove 9,10 respectively, is placed with a little positioning rotating shaft 5 in groove, and the length of little positioning rotating shaft 5 is slightly less than two small circular grooves, 9,10 degree of depth sums.The valve rod connecting groove 7 that a long strip is arranged on upper porcelain slice 4 outsides, the rectangular clamp of valve rod 1 lower end matches with valve rod connecting groove 7.Valve body 3 inner fluid flow directions are designed to, from top inflow, from following outflow.
