Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 1, the utility model embodiment provides a kind of static hydraulic balance valve, the Y-shaped structure of this static hydraulic balance valve, and it comprises valve body 1, valve gap 7, is installed on the adjusting portion on valve gap 7 and is installed on the pressure measurement portion on valve body 1.Valve body 1 inside has flowing hole, and the relative both sides of this flowing hole are communicated with water-inlet cavity and water chamber respectively.Pressure measurement portion is for detecting the pressure reduction in valve body 1, the difference of the water flow pressure of this pressure reduction and water-inlet cavity and water chamber, this pressure measurement portion comprises two pressure measuring tie-ins 2, these two pressure measuring tie-ins 2 are connected with water chamber with aforementioned water-inlet cavity respectively, the difference between both corresponding pressure measuring piece institute measuring pressures connected and described pressure reduction.Pressure measuring tie-in 2 adopts two O type circle sealing, and from turning off in case leak-stopping water.
Adjusting portion is used for the aperture of adjustment valve, and it comprises the valve shaft 8 that rotation is installed on valve gap 7 and the valve cone 3 be movably installed on valve gap 7.There is between valve shaft 8 and valve gap 7 shaft block ring 14, and both are connect by the axis gear of shoulder structure along valve shaft 8, to make valve shaft 8 only can rotate, can not move.Valve shaft 8 can apply mobile driving force to valve cone 3, now valve cone 3 will produce the shift motion pointing to flowing hole from valve gap 7, and at the end of this shift motion, sealing is pressed on flowing hole place by valve cone 3, this position, whole static hydraulic balance valve is in closed condition.
According to formula
(Q-flow, unit m
3/ h; Kv-valve parameter; Pressure reduction before and after Δ P-valve, unit Bar, 1bar=1 × 105Pa), after recording the pressure differential deltap P in valve body 1, flow value can be drawn, and calculate the opening value of valve, can accordingly regulating valve cone 3 relative to the folding size of valve body, make by the flow of valve and the flow of designing requirement consistent.Obviously, this static hydraulic balance valve can ensure that its own traffic meets design requirement, and makes the problem being not easy to occur static state hydraulic disorder in system.
In a kind of embodiment, adjusting portion also comprises the valve cone seat 5 fixed with valve cone 3, and valve cone seat 5 is threaded with valve shaft 8, is provided with gasket seal 4 between valve cone 3 and valve cone seat 5.By valve cone seat 5 actuating valve cone 3, can transmission of drive force better.
Usually there will be misoperation during above-mentioned static hydraulic balance valve work, such as the position of valve shaft 8 has adjusted complete, and in subsequent operation, valve shaft 8 is misrouted dynamic, just needs the position readjusting valve shaft 8, until the flow of valve meets design requirement.Undoubtedly, in such cases, the adjustment operation of static hydraulic balance valve can be more loaded down with trivial details.In view of this, valve shaft matching hole can be offered in valve cone seat 5, on, the aperture of valve can be known more exactly by this two-stage graduation line.Such as, when valve cone 3 presses on flowing hole, the aperture of valve is minimum, and on handwheel 12, the numerical value of display is 0, and system is in blocking state.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
