Description
Technical field
The present invention relates to a kind of self-powering type steady flow control valve, be used for fluid delivery system, especially relate to the modulating valve that a kind of pressure with the total Oil of Oil Pipeline of oil transportation drops to the required pressure in oil transportation unit.
Background technique
Along with the continuous progress of science and technology, the modulating valve that is used for fluid delivery system now is varied, but is main with manual tune mainly; In case manual tune puts in place; The pressure of its adjusting is fixing, if fluctuation appears in pipe fluid pressure, the pressure after its pressure regulation still is what fluctuate; Piping flow is altered a great deal, influence normal oil transportation.
Summary of the invention
The technical problem that the present invention will solve provides a kind of self-powering type steady flow control valve, and this pressure regulator valve has from the pressure regulatory function, promptly when upstream pressure has fluctuation, can regulate the restriction aperture automatically, thereby dependable flow is stable to a certain extent.
For overcoming the above problems, concrete technological scheme of the present invention is following: a kind of self-powering type steady flow control valve comprises valve body, valve gap, advances bellmouth and goes out bellmouth; In valve body, be provided with orifice sleeve, suit pressure-regulating sleeve and flap successively in the orifice sleeve form in the cavity between pressure-regulating sleeve and the flap and are provided with valve rod; Be with the dish spring on the valve rod, valve gap is stretched out in the upper end of valve rod, and the lower end of valve rod and flap flexibly connect; On valve rod, be provided with jump ring, the lower end surface of jump ring contacts with the upper surface of pressure-regulating sleeve; Excircle at orifice sleeve is arranged with groove, and the upper end of groove communicates with the cavity of pressure-regulating sleeve top jointly, and the lower end of groove communicates with import, is respectively equipped with the restriction of circumference uniform distribution in the lower end of orifice sleeve; Be provided with the valve seat of hollow in the bottom of valve body, the hollow portion of valve seat communicates with going out bellmouth, and valve seat and flap fasten.
The upper end of the described valve rod Stem Mut that is threaded, handwheel is connected with nut.
The middle part of described valve rod is provided with pointer.
This self-powering type steady flow control valve adopts said structure, can regulate the aperture of restriction automatically according to the variation in pressure of pipeline, the stability flow thereby the pressure reduction of assurance valve is constant basically.
Description of drawings
Fig. 1 is the structural representation of self-powering type steady flow control valve.
Embodiment
As shown in Figure 1, a kind of self-powering type steady flow control valve comprises valve body 1, valve gap 8, advances bellmouth 21 and goes out bellmouth 22; In valve body 1, be provided with orifice sleeve 4, suit pressure-regulating sleeve 5 and flap 3 successively in the orifice sleeve 4 form in the cavity between pressure-regulating sleeve 5 and the flap 3 and are provided with valve rod 7; Be with dish spring 6 on the valve rod 7, valve gap 8 is stretched out in the upper end of valve rod 7, and the lower end of valve rod 7 and flap 3 flexibly connect; On valve rod 7, be provided with jump ring 12, the lower end surface of jump ring 12 contacts with the upper surface of pressure-regulating sleeve 5; Excircle at orifice sleeve 4 is arranged with groove 13, and the upper end of groove 13 communicates with the cavity of pressure-regulating sleeve 5 tops jointly, the lower end of groove 13 with advance bellmouth 21 and communicate, be respectively equipped with the restriction 14 of circumference uniform distribution in the lower end of orifice sleeve 4; Be provided with the valve seat 2 of hollow in the bottom of valve body 1, the hollow portion of valve seat 2 communicates with going out bellmouth 22, and valve seat 2 fastens with flap 3.
The upper end of described valve rod 7 Stem Mut 10 that is threaded, handwheel 11 is connected with nut 10, can regulate the aperture of flap and the size of restriction through the rotation of handwheel 11, thereby has regulated the pressure reduction of valve.。
The middle part of described valve rod is provided with pointer 9, through the indication of pointer 9, has shown the aperture of valve.
Its working principle:
1. orifice sleeve is fixed, and there are eight restrictions 14 lower end;
2. pressure-regulating sleeve 5 usefulness dish springs 6 jack-up, and with jump ring 12 location, so pressure-regulating sleeve 5 can rise and fall with flap 3 synchronously, when flap 3 was opened, pressure-regulating sleeve also rose thereupon, and then restriction has certain aperture.When flap 3 standard-sized sheets, restriction also standard-sized sheet arrives maximum;
3. epicoele communicates with advancing bellmouth 21 through groove 13 and microstome all the time, so epicoele A internal pressure is inlet pressure P1;
4. when valve open, then medium gets into flap cavity of resorption B through restriction 14, flows to outlet through valve seat orifice again, and its variation in pressure is P1 → PB → P2; Because pressure-regulating sleeve and flap suit place do not have seal ring, so dish spring cavity pressure also is PB;
5. pressure-regulating sleeve stress balance formula is behind the valve open:
Then
,
Wherein, P
1-inlet pressure, P
B-flap chamber, dish spring cavity pressure, P
T-dish spring elastic force, D-orifice sleeve internal diameter are pressure-regulating sleeve external diameter, d-valve rod external diameter.
Under a certain operating mode, pressure-regulating sleeve place one a certain height.Work as P
1During increase, inevitable pressure-regulating sleeve moves down, and restriction is reduced, and then the restriction pressure loss increases, and keeps the constant flow unchanged of PB; Otherwise when P1 reduced, pressure-regulating sleeve moved up, and throttling is strengthened, and the restriction pressure loss reduces, and it is constant that its result also keeps PB, then stablized the flow of valve.
When should outlet pressure P2 changing, cause also that pressure-regulating sleeve is corresponding or rise or fall that it is relatively stable also can to keep flow.
