5pa.
Owing to being provided with flow measurement orifice plate 3 at water intake 20 place, for the static hydraulic balance valve in present embodiment, when Δ P is 1Bar, the flow flowing through the liquid of static hydraulic balance valve is kvs, and it is definite value.
In the present embodiment, by the pressure-detecting device be connected with the first pressure measuring tie-in 22 and the second pressure measuring tie-in 23, the pressure difference before and after flow measurement orifice plate 3 can be detected, i.e. Δ P.And the depth be deep into by regulating spool in flow channel, the pressure reduction before and after flow measurement orifice plate can be changed, thus the flow flowing through flow measurement orifice plate can be changed.According to foregoing, the precise measurements of the fluid flow flowing through static hydraulic balance valve can be obtained, thus be conducive to overcoming static state hydraulic disorder.And less demanding like this to the machining accuracy of spool (determining the kv value of valve), compared with prior art, so just can reduce difficulty of processing and cost of production, be convenient to production in enormous quantities.
Particularly, described water intake 20 and water outlet 21 are provided with adpting flange, are respectively used to be connected with intake pipe and outlet conduit.
Described valve body 2 has a bump 24, described bump 24 forms y-type structure with water intake 20, water outlet 21; Described static hydraulic balance valve also comprises controlling mechanism 4, and described controlling mechanism 4 is fixed on described bump 24, and is connected with described spool, is deep into depth in described flow channel in order to regulate described spool.
Described static hydraulic balance valve comprises the upper cover 5 on the bump 24 being fixed on described valve body 2; Described spool comprises the valve cone 25, valve cone seat 26 and the valve shaft 27 that link together; Described valve shaft 27 is arranged on described upper cover 5, and adopts back-up ring to be connected with between described upper cover 5; Described valve cone seat 26 is arranged on the bottom of described valve shaft 27, and described valve cone 25 is connected and fixed with described valve cone seat 26; Described controlling mechanism 4 is connected with valve shaft 27.
Particularly, described upper cover 5 inside is provided with shrinkage pool, and the shaft shoulder of described shrinkage pool and valve shaft 27 compresses, and moves up to limit valve shaft 27; Meanwhile, the top of described valve shaft 27 is provided with back-up ring 6, moves down to limit valve shaft 27.
Described controlling mechanism 4 comprises handwheel, and described handwheel is connected with valve shaft 27, rotates in order to drive described valve shaft 27.Described handwheel is provided with scale unit, and described scale unit indicates the rotating cycle of described handwheel.
Particularly, as shown in Figure 2, described scale unit can comprise the first subscale mark unit 40 and the second subscale mark unit 41, the whole number of turns of described first subscale mark unit 40 in order to indicate described handwheel to rotate, the position that described second subscale mark unit 41 rotates in order to indicate described handwheel.Such as, indicate 2 at the first subscale mark unit 40, when the second subscale mark unit 41 indicates 3, represent that described hand wheel rotating 2.3 encloses.
Particularly, between described first pressure measuring tie-in 22 and described valve body 2, and be provided with O type circle between the second pressure measuring tie-in 23 and valve body 2, in order to realize sealing.
Particularly, be provided with gasket seal between described valve cone 25 and valve cone seat 26, described gasket seal plays buffer function, and can realize the complete turn-off function of valve.
Particularly, be connected by square hole between handwheel with valve shaft 27, and fixed by pad 10 and lock screw 11; Be threaded between valve shaft 27 with valve cone seat 26, be specifically as follows left-handed trapezoidal thread to connect, such handwheel is left-handed to rotate a circle, and drives valve shaft 27 synchronous axial system, and the inside shrinkage pool end face of the top shaft shoulder of valve shaft 27 and upper cover 5 compresses, thus valve shaft 27 can be limited move up.Back-up ring 6 blocks valve shaft 27 in the outside of upper cover 5, can limit valve shaft 27 and move down.Adopt Flange joint between upper cover 5 and valve body 2, when valve shaft 27 rotates, upper cover 5 maintains static.Simultaneously, valve cone seat 26 is limited by upper cover 5, make it not rotate with valve shaft 27 and rotate, can only move up and down along the axis of valve shaft 27 under the drive of valve shaft 27, thus the regulatory function of valve can be realized, that is: left-handed along with valve shaft 27, valve cone seat 26 constantly rises, until reach the limit of stroke, now, valve has peak rate of flow; And along with valve shaft 27 dextrorotation, valve cone seat 26 constantly declines, until reach the limit of position, now, sealed completely between valve body 2 and valve cone seat 26 by gasket seal 7, now, valve is blocked, and its flow is 0, and described static hydraulic balance valve plays the effect of stop valve.
In the present embodiment, the inside of described valve shaft 27 is provided with valve opening regulon; Described valve opening regulon comprises the adjustment push rod 14 and locking 8 bar that vertically set gradually, and the lower end of described locking rod 8 leans the inwall of described valve cone seat 26.In preferred scheme, described adjustment push rod 14 can adopt screw rod.
Particularly, after described static hydraulic balance valve has been debugged in systems in which, the maximum opening of valve can be set in the following manner: take off handwheel cap 12, rotate clockwise with spanner (as inner hexagon spanner etc.) and regulate push rod 14, make adjustment push rod 14 withstand locking rod 8 and drive it to move down together, until locking rod 8 withstands valve cone seat 26 inwall, now namely define the peak rate of flow of valve.When pipeline need safeguard or break down need repairing time, static hydraulic balance valve can be closed completely, to safeguard accordingly or maintenance work.When work completes, only slowly need open static hydraulic balance valve, until valve cone seat 26 inwall contacts with locking rod 8 again, namely reaching the valve cone position of debugging originally, is now namely debugged correct flow value at that time by the flow value of static hydraulic balance valve.This function enormously simplify operation, avoids general static hydraulic balance valve once after closing, and needs the drawback repeating to debug.
The static hydraulic balance valve that present embodiment provides, it arranges flow measurement orifice plate 3 at water intake 20 place, and the both sides of flow measurement orifice plate 3 are respectively arranged with the first pressure measuring tie-in 22 and the second pressure measuring tie-in 23 be connected with pressure-detecting device, like this when flowing through the flow of described static hydraulic balance valve by spool adjustment, the flow exact value of described static hydraulic balance valve is flowed through described in can being known exactly by the pressure reduction measured before and after flow measurement orifice plate, so just contribute to the precision improving system debug, overcome the problem of static state hydraulic disorder.
Be understandable that, the illustrative embodiments that above mode of execution is only used to principle of the present utility model is described and adopts, but the utility model is not limited thereto.For those skilled in the art, when not departing from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement are also considered as protection domain of the present utility model.
