Abstract
A high-pressure constant-flow regulating valve comprises a base, a spring, a lower mandrel, an inner valve body, a valve body, a valve element, a pressing plate, a rotary disk, a handle, a dial, an upper mandrel, an inlet cavity and an outlet cavity. The valve body is located between the pressing plate and the base and provided with the inlet cavity and the outlet cavity. The inner valve body is located in the inlet cavity in the valve body. The lower mandrel is inserted in the inner valve body, the spring is arranged at the lower end of the lower mandrel, and the upper end of the lower mandrel abuts against the lower end of the upper mandrel. The valve element is inserted in the upper mandrel. The upper mandrel is located in the outlet cavity in the valve body. The upper end of the valve element penetrates through the pressing plate, the rotary disk and the handle. The rotary disk is fixed to a rotary disk bearing. The handle is located above the rotary disk. The dial is fixed below the rotary disk. The high-pressure constant-flow regulating valve can be used in the oilfield industry and the metallurgical industry, pressure and flow can be visually regulated, the pressure and the flow in a pipeline can be accurately reflected, and the work intensity of workers is relieved.
Description
Technical field: the present invention relates to a kind of modulating valve, especially a kind of high pressure constant flow control valve.
Background technique: not measuring during toward underground high-voltage water filling in oil field, is that the practical work experience of estimating pressure gauge and workman by operator is manually adjusted valve, realizes the metering toward underground flooding, shines into like this energy waste.In hot rolling mill in metallurgy industry, in rolling process, with dephosphorize by high pressure water, remove billet surface oxide layer, be also manually to adjust valve by operator's practical work experience in this process, increased the intensity of workman's work.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the invention provides a kind of high pressure constant flow control valve that can adjust intuitively pressure and flow.
For achieving the above object, the technical solution used in the present invention is: high pressure constant flow control valve, comprises base, spring, lower mandrel, inner valve body, valve body, spool, pressing plate, rotating disc, handle, dial, rotating disc, upper mandrel, snout cavity and outlet plenum.Valve body, between pressing plate and base, which is provided with snout cavity and outlet plenum.The snout cavity place of inner valve body in valve body.Lower mandrel inserts in inner valve body, and its lower end is provided with spring, and upper end withstands on the lower end of mandrel.Spool is inserted in mandrel.The outlet plenum place of upper mandrel in valve body.The upper end of spool is through pressing plate, rotating disc and handle.Rotating disc is fixed on rotating disc bearing.The top of handle in rotating disc.Dial is fixed under rotating disc.
The present invention can be used in oil field and metallurgy industry, adjusts intuitively pressure and flow, can go out manifold pressure and flow by accurate response, has alleviated the intensity of workman's work.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is carried out to clear, intactly description, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment who obtains under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1: high pressure constant flow control valve, comprises base 1, spring 2, lower mandrel 4, inner valve body 5, valve body 9, spool 10, pressing plate 11, rotating disc 12, handle 13, dial 16, rotating disc 12, upper mandrel 18, snout cavity 21 and outlet plenum 20.Valve body 9, between pressing plate 11 and base 1, which is provided with snout cavity 21 and outlet plenum 20.Outlet plenum 20 places of inner valve body 5 in valve body 9.Lower mandrel 4 inserts in inner valve body 5, and its lower end is provided with spring 2, and upper end withstands on the lower end of mandrel 18.Spool 10 is inserted in mandrel 18.Snout cavity 21 places of upper mandrel 18 in valve body 9.The upper end of spool 10 is through pressing plate 11, rotating disc 12 and handle 13.Rotating disc 12 is fixed on rotating disc bearing 15.The top of handle 13 in rotating disc 12.Dial 16 is fixed on rotating disc 12 times.Base 1 and pressing plate (11) be by spool partial fixing in valve body 9, can bear its load downforce.Spring 2 is that it maintains lower valve core 4 and moves up and down maintenance balance.Lower valve core 4 is used for ensureing flow output.Inner valve body 5 is to lower valve core 4 location and flow input (going out) mouthful use.Flange 6 is connected use with pipeline.Valve body 9 is to ensure pressure-bearing and fixed spool part position.Spool 10 is to connect lower valve core 4 rotating disc bearings 15, handle 13 and nut 14 use.Rotating disc 12 can obtain the flow value of output by rotatable handle 13.Handle 13 makes rotating disc 12 overlap with dial 16 can to obtain the flow value of output by its rotation.Nut 14 fixed handle 13 use.15 its effects of rotating disc bearing are fixing rotating disc 12 and handle 13.Dial 16 is instruction flows.Upper mandrel 18 is the positions between fixed spool 10 and valve body 9.
High pressure constant flow control valve of the present invention is the valve that integrates two valves, one is as pressure-compensated valve, what it had a sliding bush type presses orifice plate (lower mandrel), be used for maintaining one all the time than the middle pressure chamber of the high 0.4MPa of outlet pressure, they are two years old, one has the orifice plate (lower mandrel) of the constant pressure difference of 0.4MPa, and this orifice plate (lower mandrel) is that its function is adjust flux by the graduated stick control of top band.
Maintaining constant pressure reduction is undertaken by recuperation valve piston (lower mandrel), utilize spring to make it be subject to the pressure of certain pretension, this pressure acts on again (lower mandrel) on superincumbent recuperation valve piston, in the time that inlet pressure P1 increases, lumen pressure P 2 also increases thereupon, destroyed the balance at piston (lower mandrel) two ends simultaneously, piston (lower mandrel) is moved down, because piston (lower mandrel) moves down, the pressure in outlet pressure chamber is increased, finally make the pressure reduction on Flow-rate adjustment orifice plate (lower mandrel) both sides constant, thereby flow remain unchanged.
Do not needing under outside gas and electric energy condition, in the time there is any variation in inlet pressure, piston (lower mandrel) all can slide, and reaches new balance, and this with inlet pressure variation, the valve of constant output flow is not high pressure constant flow control valve.
When highly pressurised liquid is in the time that pipeline enters import, slow circumvolve handle, rotate to specified position on dial, handle band moving mandrel and lower mandrel rotate, carry out throttling, spring is started working thereupon, makes the upper (lower) slip of lower mandrel, reach balance inlet outlet pressure differential object, make its constant flow output.
