Abstract
The utility model discloses a high-abrasion resistance hydraulic flow divider valve which comprises an oil cylinder, a valve body and a flashboard, wherein the oil cylinder is electrically and hydraulically driven; the valve body is provided with a valve through hole, and the valve body is in a double-clip mode and internally provided with an insertion slot; the flashboard is provided with a corresponding through hole and penetrates through the insertion slot of the valve body; one end of the flashboard is connected with the piston rod of the oil cylinder, and the closing and opening of the valve through hole under the driving of the piston rod are realized; and the valve through hole of the valve body is provided with an abrasion-resistant layer. The high-abrasion resistance hydraulic flow divider valve disclosed by the utility model is more excellent in sealing effect and can prevent the leakage caused by flashboard abrasion; and according to the utility model, the valve body is excellent in abrasion resistance.
Description
Technical field
The invention belongs to the valve of hydraulic control, be mainly used in digging up mine, the flowing valve of the industry medium transportations such as iron and steel, coal, electric power and food.
Background technique
At present, the flowing valves such as coal, metallurgy, mine, electric power, the extensive practical Parallel Slide Valves of food service industry, push-pull valve are used for the medium circulation of every profession and trade.Wherein be used for the circulation of coal slurry and filter residue slurry in mining and the Iron And Steel Industry; Reach the circulation with the clear water of suspended matter for waste water, mud, dirt in the purification plant; And in the paper industry, be used for the paper pulp of any concentration, the transportation circulation of material aqueous mixtures; Sugar industry then is used for beet washing, syrup, squeezes the juice, the circulation of fruit juice etc.; Also have food industry, then be used for the circulation that washing and flushing device, grain haulage device, mash and power station ash disposal are used for the media such as lime-ash slurry.In the prior art, flashboard is a complete flat board, and the flashboard lower edge is basic concordant with valve body lower end when therefore closing, and this is because flashboard is oversize, and the displacement that can cause piston rod 5 to rise when opening is excessive.Therefore after the flashboard lower edge was worn, valve fitted badly and causes easily leakage when closing.And in these industrial media processes of circulation, easily flashboard is caused very large wearing and tearing, form leakage thereby cause valve not seal, therefore can not satisfy industrial production; When circulating, medium also can produce wearing and tearing to valve body itself simultaneously.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this invention is to provide a kind of high abrasion hydraulic synchronizing valve, it can guarantee still have good sealing effect after long-term the use, and has good wear resistance.
Technological scheme: for achieving the above object, the technical solution used in the present invention: a kind of high abrasion hydraulic synchronizing valve, comprise the oil cylinder, the valve body that is provided with the valve through hole and the flashboard that are driven by electric liquid, described valve body is wafer type, interpolation slit is left in inside; Described flashboard is provided with corresponding through hole, and passes the valve body interpolation slit, and an end is connected with the piston rod of oil cylinder, and realizes closing and opening of valve through hole under the drive of piston rod; The valve through hole of described valve body is provided with wearing layer simultaneously.
Since this hydraulic synchronizing valve gate in the middle of opened corresponding through hole, overlap and can realize the unlatching of valve moving up and down the valve through hole that makes on itself and the valve body under the piston rod effect.Piston rod only needs less stroke just can make valve opening like this, even the flashboard through hole has wearing and tearing, but the gate edge also has very large zone to circulate by block media.Owing at the valve through-hole wall wearing layer is set, improved greatly the wear resistance of valve body simultaneously.
As preferably, described wearing layer is the abrasion resistance alloy steel ring, and this abrasion resistance alloy steel ring adopts high manganese steel, and is nested on the inwall of valve through hole of valve body.
As preferably, described wearing layer is the wear-resistant ceramic that sticks on the valve through-hole wall.
As preferably, described valve body upper end is provided with support, this support is provided with position limit switch, thereby can feed back and set the opening-closing size of the Stroke Control valve that flashboard moves up and down, and when wearing and tearing occur in flashboard, position limit switch can be moved and be adjusted to correct position, thus the change of regulator Board position, and then solve the leakage that wearing and tearing bring.
Beneficial effect: compared with prior art, the present invention has the following advantages: have better sealing effect, prevent because the leakage that the flashboard wearing and tearing cause; Valve body has good wear-resisting property simultaneously.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of flashboard of the present invention;
Fig. 3 is the structural representation of abrasion resistance alloy steel ring of the present invention.
Oil cylinder 1, valve body 2, flashboard 3, valve through hole 4, piston rod 5, support 6, position limit switch 7.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiments only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
The hydraulic synchronizing valve of prior art, its flashboard 3 is complete steel plate, and flashboard 3 lower ends are substantially concordant with valve body 2 lower ends when closing, also can be not oversize even there is part to stretch out, thereby because can add like this stroke realization unlatching that large tank 1 piston rod 5 makes progress, but the stroke of oil cylinder 1 piston rod 5 is limited.Therefore flashboard 3 lower ends are worn easily and occur leaking.
Shown in Fig. 1～2, a kind of hydraulic synchronizing valve, comprise by oil cylinder 1, the wear-resistant ceramic of electric liquid driving and make valve body 2 and 304 stainless steel flashboards 3, described wherein valve body 2 is square shape wafer type structure, is provided with valve through hole 4, and interpolation slit is left in the centre, described flashboard 3 also is provided with respective through hole, and passes the interpolation slit in the middle of the valve body 2, and an end is connected with the piston rod 5 of oil cylinder 1, and under the drive of piston rod 5, move up and down, realize closing and opening of valve through hole 4.In the valve body upper end support 6 is set simultaneously, this support 6 is provided with position limit switch 7, thereby can feed back and set the opening-closing size of the Stroke Control valve that flashboard moves up and down, and when wearing and tearing occur in flashboard, position limit switch 7 can be moved and be adjusted to correct position, thereby the change of regulator Board position, and then solve the leakage that wearing and tearing bring.
In addition, as shown in Figure 3, we can be on the valve through-hole wall of valve body the abrasion resistance alloy steel ring of a nested high manganese steel material, perhaps by pasting wear resistant ceramic on the valve through-hole wall, can improve equally the wear-resisting property of valve body, thereby will extend to working life more than 3 years.
Since this hydraulic synchronizing valve gate in the middle of opened corresponding through hole, overlap and can realize the unlatching of valve moving up and down the valve through hole 4 that makes on itself and the valve body 2 under piston rod 5 effects.The less stroke of 5 need of piston rod just can make valve opening like this, even flashboard 3 through holes have wearing and tearing, but the gate edge also has very large zone to circulate by block media.
