Abstract
The invention relates to a high-pressure water scale removal two-way valve, whose working pressure is 38MPa, wherein the invention is characterized in that: said two-way valve is the lead, controlled by low-pressure medium; the lead piston and the valve rod form the booster, with the auxiliary valve pin fixed on the end of valve rod, to be inserted into one valve; via the motion of piston, the auxiliary valve pin can close and open the two-way valve; the web of valve pin has damping hole, to balance two side functions and release the switch impact of two-way valve. The invention has the advantages that: it has simple structure, high working pressure, long service life, and reliable operation.
Description
Technical field
High-pressure water descaling two-way valve is usually used in the control that hot rolled steel high-pressure water descaling nozzle opens and closes, and is the important technique measure that guarantees the rolled piece surface quality.
Background technique
In recent years, because hot rolled steel production line de-scaling hitting power has higher requirement, also more and more harsher to the design of de-scaling Twoway valves.The current de-scaling Twoway valves that has with reference to Hydraulic Poppet Valve design, complex structure, element is short working life, will change with about three months, has brought a lot of troubles to production.
Summary of the invention
The present invention relates to 38MPa high-pressure water descaling Twoway valves: function has unidirectional, throttling and commutation.Guide's control media of general hydraulic pilot Twoway valves draws from the high pressure water of native system or the independent hydraulic station that is provided with.The former contains hard fine iron scale particle because hot rolled steel uses circulating water in the water, cause pilot valve easily to stop up, and requires to refilter.Latter Yi Zaocheng environmental pollution and the existence hidden danger of catching fire need be got up whole hydraulic station cover.Therefore the high-pressure water descaling Twoway valves is selected at structural design, element material, and aspect such as manufacturing process remains more deep research.
Mode of execution
The object of the present invention is achieved like this: Twoway valves is the one-level guide, low piezodielectric control.The guide partly adopts piston type, and main valve is the bevel-type auxiliary spool, and first guide piston and main valve are installed in the same valve body.Its principle is: drive auxiliary spool by designed pressurized machine, handle the effect that online descaling jet opens and closes.Pressurized machine is made up of piston and plunger; The space of auxiliary spool in order to cause main valve chamber to hold plunger, valve pocket, valve seat and connect main line.On the auxiliary spool web, offer damping hole, not only make the active force of spool web both sides be able to balance, make the active force that drives spool drop to minimum, and, the travelling speed of spool that the size of damping hole is also given, and the effect of closing impact that slows down Twoway valves is arranged, this is to realize only road of the present invention part.
Working medium for ultrahigh pressure (25-38MPa) pilot valve adopts low-pressure water, the working medium of general high voltage (less than 25MPa) pilot valve draws the pressurized air from workshop gas net, require to refilter and problem of environment pollution caused thereby realize removing high-pressure water descaling guide medium, realize the high-pressure water descaling Twoway valves technological scheme of initiative both at home and abroad.
Description of drawings
Below in conjunction with accompanying drawing invention is described further:
Fig. 1 is the structural drawing of high-pressure water descaling Twoway valves of the present invention.
Fig. 2 is the structural drawing side view of high-pressure water descaling Twoway valves of the present invention.
Among the figure 1---cover plate, 2---the O RunddichtringO, 3---cylinder barrel, 4---the O RunddichtringO, 5---cotter pin, 6---nut, 7---piston, 8---y-type seal ring, 9---the O RunddichtringO, 10---dividing plate, 11---the O RunddichtringO, 12---y-type seal ring, 13---check ring, 14---the O RunddichtringO, 15---valve body, 16---support ring, 17---valve pocket, 18---auxiliary spool, 19---seal ring, 20---valve rod, 21---packing ring, 22---nut, 23---cotter pin, 24---the O RunddichtringO, 25---valve seat, 26---bolt, 27---spring washer.
The import and export of figure mesohigh water, generally by A to B, and can be from B to A. Shown position is the shape of closing of two-port valve Attitude; When piston 1 commutation, spool 18 is oppositely mobile, realizes the commutation of two-port valve.
Because adopt above-mentioned design proposal, the present invention has following feature: Twoway valves is the one-level guide, low piezodielectric control, pilot valve and main valve two pressure chambers independently separately in same valve body.Auxiliary spool and pressurized machine constitute the feature card of valve, realize the switching effect of Twoway valves.Offer the impact of closing that damping hole makes the double side acting equilibrium of forces and slows down Twoway valves on the spool web.This is only road of the present invention part.
High-pressure water descaling Twoway valves of the present invention is the proprietary technology innovation item, compact structure, working pressure height, reaction are fast, long service life, working stability is reliable, contamination resistance is strong, easy to maintenance.Therefore, the invention provides the high-pressure water descaling Twoway valves of brand-new type.
The present invention not only is used for the switching of high-pressure water descaling control valve, also comprises commutation, throttling, unidirectional control and the accumulator minimum level valve of high pressure water system.
Claims (3)
1, the guide of Twoway valves part and main valve are divided into separately the independently pressure chamber of two different mediums by dividing plate with valve in same valve body;
2, auxiliary spool web both sides stress balance formula is with the opening and closing speed of damping hole design spool and the impact of closing that slows down valve;
3, the working medium of extra high voltage system pilot valve adopts low-pressure water;
