Abstract
Disclosed is a throttling valve capable of controlling the amount of passed fluids. The throttling valve is composed of a valve body, a valve core, a locking nut, a hand wheel and a seal ring, an inner cavity of the valve body is an axial step hole which has a large the left end and a small right end, an inner conical surface is arranged between a middle medium aperture and a minimum aperture of a fluid inlet, conical degrees of the inner conical surface and an outer conical surface of the valve core are same, and the outer conical surface is arranged at the right end of the valve core and matched with the inner conical surface of the valve body to adjust the flow amount. During working, the valve core is located in the axial step hole of the valve body, the hand wheel is rotated to change the axial relative position of the valve core and the valve body so as to change a relative gap of the valve core outer conical surface and the valve body inner conical surface, and flow amount adjustment is achieved; the locking nut is installed on a thread surface at the left end of the valve body, the locking nut fixes the axial position of the valve core and the valve body after the valve core is adjusted to a required position, stability of the flow amount is guaranteed, and the throttling valve is simple in structure, low in manufacture cost and convenient to use.
Description
Technical field
The utility model relates to a kind of fluid-flow control apparatus, especially can change what throttle valve of flow.
Background technique
Many occasions in industrial and agricultural production and the daily life, the size of needs control fluid flow.Wherein flow control valve commonly used has gate valve, butterfly valve, ball valve, safety check, hydropneumatic throttle valve, series flow control valve etc.Gate valve, butterfly valve, ball valve, safety check multiplex in fluid circuit open, turn-off, stop the reverse flow occasion, adjust flux uses inconvenience.The precision that hydropneumatic throttle valve, series flow control valve are regulated the control flow is high, but manufacture cost is high, price is high, for the general occasion of Flow-rate adjustment required precision, uses uneconomical.
Summary of the invention
For solving the general occasion of Flow-rate adjustment required precision, existing flow control device manufacture cost is high, price is high, the problem that its usage economy is poor, the utility model provides a kind of throttle valve, this throttle valve can change the fluid flow that passes through easily, and simple in structure, low cost of manufacture.
The technological scheme that its technical problem that solves the utility model adopts is: throttle valve is comprised of valve body, seal ring, locking nut, spool, handwheel etc.It is characterized in that: the outer conical surface that spool is arranged in the body cavity step hole cooperates with the valve body internal conical surface, changes spool with respect to the axial position of valve body, realizes Flow-rate adjustment.Described body cavity is the little step hole of the large right-hand member of axial left end, place, left end maximum diameter of hole is tapped hole, middle intermediate pore size place is the matching surface of Sealing and valve body, the axial minimum-value aperture of right-hand member is fluid input, be internal conical surface between middle intermediate pore size and the fluid input minimum-value aperture, this internal conical surface has identical tapering with the spool outer conical surface, and the valve body radial hole is fluid output.Described poppet shaft is followed successively by outer conical surface, the right shaft shoulder of o-ring groove cylndrical surface, o-ring groove cylndrical surface, the left shaft shoulder of o-ring groove cylndrical surface, intermediate section cylndrical surface, the transition circle conical surface, outer cylinder flank of thread to right-to-left.In order locking nut is screwed in from spool left end outer cylinder flank of thread during assembling, handwheel is fixed to spool outer cylinder flank of thread left end, seal ring is packed into from the spool right-hand member in the o-ring groove, spool right-hand member outer conical surface is aimed at valve body left end axial bore center and is inserted valve body, rotation hand wheel screws in spool outer cylinder flank of thread in the valve body left end tapped hole, in the valve core seal ring groove seal ring is housed, the sealing circle contacts with valve body cylindrical hole internal surface, prevents that fluid leakage is to the valve body left end.Rotation hand wheel, the relative valve body of spool moves axially, change the relative gap of spool outer conical surface and valve body internal conical surface, realize Flow-rate adjustment, on the spool left end flank of thread locking nut is housed, after spool is adjusted to and required the position, with the axial position of locking nut fixed spool and valve body, guarantee stability of flow.
The beneficial effects of the utility model are, fluid can change match with the valve body gap of the conical surface of spool easily by throttle valve, and control is by what of fluid flow, and simple in structure, cost is low, and is easy to use.
Description of drawings
Below in conjunction with accompanying drawing and example this practical property is further specified.Obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on embodiment of the present utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment who obtains under the creative work prerequisite.
Fig. 1 is axial section structural representation of the present utility model.
Fig. 2 is valve body sectional view of the present utility model.
Fig. 3 is spool plan view of the present utility model.
1. valve bodies among Fig. 1,2. seal ring, 3. locking nut, 4. spool, 5. handwheel.
Embodiment
Throttle valve among Fig. 1 is by valve body (1), seal ring (2), and locking nut (3), spool (4), handwheel (5) etc. partly form.At first locking nut (3) is screwed in from spool (4) left end outer cylinder flank of thread during assembling, handwheel (5) is fixed to spool outer cylinder flank of thread left end, in then seal ring (2) being packed into o-ring groove from spool (4) right-hand member, then spool (4) the right-hand member conical surface is aimed at valve body (1) left end axial bore center, spool (4) inserts valve body (1), rotation hand wheel (5) screws in spool (4) outer cylinder flank of thread in valve body (1) the left end tapped hole, seal ring (2) is cooperated with intermediate pore size cylndrical surface in the middle of the valve body (1), prevent that fluid from flowing to valve body (1) left end.Forward and reverse rotation hand wheel (5), spool (4) relatively valve body (1) move axially, and change the relative gap of spool (4) conical surface and valve body (1) conical surface, realize Flow-rate adjustment.
Working principle of the present utility model is: supplying water enters from valve body (1) right-hand member fluid input, by the relative gap of spool (4) outer conical surface and valve body (1) internal conical surface, flows out from the outlet of valve body (1) radial fluid.Handwheel (5) is rotated in the forward, spool (4) relatively valve body (1) moves right, the relative gap of spool (4) outer conical surface and valve body (1) internal conical surface reduces, the flow that passes through diminishes, until the fully applying of spool (4) outer conical surface and valve body (1) internal conical surface, flow control valve cuts out, and the flow that passes through is zero, and handwheel (5) counterrotating can tune up the flow that passes through.When being adjusted to the flow of requirement, with the relative position of locking nut (3) fixed spool (4) with valve body (1), guarantee stability of flow.
