Model utility content
The purpose of this utility model be exactly provide a kind of in order to overcome defect that above-mentioned prior art exists and be convenient to open, pressure reduction is large, cavitation-preventive is effective, compact structure, easy to maintenance, adjust the accurate reliable flow-adjustable valve with valve rod hinging structure of stream.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of flow-adjustable valve with valve rod hinging structure, comprise valve body, valve rod, the valve gap be connected with valve body by bolt, be arranged on valve inner and the sleeve be connected with valve gap and be arranged on sleeve inner and the lock cylinder be slidably connected with sleeve, described lock cylinder comprises lock barrel and is arranged on lock cylinder plate in lock barrel, and the lower end of described valve rod is fixedly connected with lock cylinder plate by valve rod hinging structure through the valve rod hole of bonnet central.
Described valve rod hinging structure is a connection piece, this link bottom is establish threaded cylindrical body, and passes the center hole of lock cylinder plate, is fixedly connected with lock cylinder plate by nut, link top is a semicircle connecting plate with holes, and hinged by the lower end of bearing pin and valve rod.
Described upper cartridge is solid barrel, and bottom offers multiple sleeve spray orifice along barrel surface, and described sleeve spray orifice is greater than the aperture at sleeve lining place in the aperture at sleeve outer rim place.
Described lock cylinder plate is also provided with multiple pressure compensation opening, and described pressure balance hole number is 3-6.
Described upper cartridge and the joint of valve gap are provided with seal ring, and bottom is connected with valve seal by U-shaped seal ring.
The slip surface of described sleeve lining and lock cylinder is provided with one-way sealing seal.
Described valve gap is also provided with the driving arm be bolted on valve gap.
Central hole on described valve gap is provided with sealing axle sleeve, and described sealing axle sleeve is connected with valve rod and valve bonnet seal respectively by seal ring.
Compared with prior art, the utility model has the following advantages:
One, be convenient to open: due to the nonsymmetry of valve body, when the effect be under pressure, valve rod, sleeve, can produce certain displacement or disalignment between lock cylinder, when making valve rod can not pull open valve smoothly, by hinged stem structure, allow the axis of valve rod and the central axis of lock cylinder and sleeve to produce angular deflection, make between sleeve and lock cylinder, to keep coaxial, easily valve rod can be pulled out, thus open valve.
Two, pressure reduction is large, cavitation-preventive is effective: due to the head-on collision principle of sleeve surrounding spray orifice, and valve is not easily cavitated when pressure reduction is large, and the driving force of valve rod is not by the impact of valve internal pressure.
Three, compact structure, easy to maintenance: guiding and spray orifice disjunctor formation valve pocket make installation and maintenance simple and convenient, can change Sealing online.
Four, adjust stream accurately reliable: omnidistance flow is controlled and be linear, the utility model is only made up of valve body, valve gap, sleeve, valve rod and lock cylinder, and in addition thereto without quick-wear part, the life-span of valve is long, and replacing conveniently.
