Description
Technical field
The utility model relates to a kind of moushroom valve, particularly single-lobe moushroom valve.
Background technique
Moushroom valve is a kind of open-shut device is disk, the valve that disk is axle center with valve rod, rotates along sealing surface of seat.Be mainly used in the industries such as polysilicon, organosilicon and Coal Chemical Industry.In its working procedure, in the higher granular of hardness or dust-like material and slurry delivery system, conventional valves to be made seal failure, heat lock by material wearing and tearing, the high-velocity fluid of jumping the queue therebetween very soon, leak outside and the thin and easy reason such as wearing and tearing and cause working life short of the hard coat of moushroom valve due to valve sealing face to valve sealing face erosion, sealing effect is poor.
Moushroom valve is that the one realizing switch by sliding disc changes up pass type valve soon.Its design is special in the material with wearing and tearing, erosion Mechanism, and due to the normal work that it is long-term continuously under bad working environments, there will be the valve that wearing and tearing have to often change or keep in repair, short operation in working life is inconvenient.Valve body valve gap connecting part is easily leaked; Filler easily loosen makes medium to external leakage, and valve in Long-Time Service process stem packing group wearing and tearing after, filler loosen, easily cause filler from stem packing to external leakage.
Model utility content
The purpose of this utility model provides a kind of long service life, structure simple single-lobe moushroom valve to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, a kind of single-lobe moushroom valve designed by the utility model, comprise valve body, valve body comprises inlet pipe mouth, outlet spout and valve pocket, it is characterized in that: the valve shaft being provided with bending structure in described valve pocket, described valve shaft comprises cross bar and rotating shaft, described cross bar is arranged in valve pocket, rotating shaft one end and cross bar one-body molded, the other end to be arranged on valve body and to stretch out valve body outer end, between cross bar and inlet pipe mouth, moushroom valve is installed, between cross bar and moushroom valve, counterbalance spring is installed, the joint of rotating shaft and cross bar is provided with spring, this spring one end and valve body are conflicted, the other end is arranged on cross bar.
Preferably, described valve body is also provided with filler, pedestal, Gland, elastic component and handle, and described pedestal, filler, Gland, elastic component and handle are successively set in rotating shaft.
Preferably, described valve body is provided with sealing surface, sealing face and moushroom valve end face inconsistent.
Preferably, described moushroom valve is provided with sealing surface.
The single-lobe moushroom valve that the utility model obtains, the spinning of disc type moushroom valve, self-grind and strengthen the automatically cleaning ability of valve seat, counterbalance spring and spring can make stress keep evenly, extending the life-span of packing, and moushroom valve occurs wearing and tearing in using process, it utilizes the elasticity of counterbalance spring can effectively prevent from revealing, keep sealing, have autonomous compensate function, long service life, simultaneously this structure also has and prevents adverse current, is equivalent to the function of safety check; In movement process, the sealing surface of whole moushroom valve is close to sealing seat under the action of the spring always, prevents particulate matter from entering sealing surface.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of embodiment.
In figure: valve body 1, valve shaft 2, moushroom valve 3, cross bar 4, rotating shaft 5, spring 6, sealing seat 7, counterbalance spring 8, valve pocket 9, inlet pipe mouth 10, packing ring 11, pedestal 12, filler 13, Gland 14, elastic component 15, handle 16, nut 17.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figure 1, a kind of single-lobe moushroom valve that the present embodiment provides, comprise valve body 1, valve body 1 comprises inlet pipe mouth 10, outlet spout and valve pocket 9, the valve shaft 2 of bending structure is provided with in described valve pocket 9, described valve shaft 2 comprises cross bar 4 and rotating shaft 5, described cross bar 4 is arranged in valve pocket, rotating shaft 5 one end and cross bar 4 one-body molded, the other end to be arranged on valve body and to stretch out valve body outer end, moushroom valve 3 is installed between cross bar 4 and inlet pipe mouth 10, counterbalance spring 8 is installed between cross bar 4 and moushroom valve 3, rotating shaft 5 is provided with spring 6 with the joint of cross bar 4, this spring 6 one end and valve body 1 are conflicted, the other end is arranged on cross bar 4, described valve body 1 is equipped with sealing seat 7, sealing seat 7 is arranged on the intersection of inlet pipe mouth 10 and valve pocket 9, the sealing surface of sealing seat and moushroom valve is inconsistent, mainly in order to further better seal anti-leak.
Described valve body 1 is also provided with filler 13, pedestal 12, Gland 14, elastic component 15 and handle 16, described pedestal 12, filler 13, Gland 14, elastic component 15 and handle 16 are successively set in rotating shaft 5, use nut 17 to rotate fixing above-mentioned each parts at rotating shaft 5 end, between pedestal and cross bar, packing ring 11 is also installed.
Above-mentioned single-lobe moushroom valve is described further: utilize moushroom valve 8 to make the sealing surface of moushroom valve fit tightly on sealing seat 7 all the time by counterbalance spring pressure, because counterbalance spring 8 has elasticity, help counterbalance spring 8 can make to use by long-time the wearing and tearing produced, also can not leak, in moushroom valve 3 opening-closing process, rotating shaft 5 is provided with spring 6 with the joint of cross bar 4, and the stress that spring 6 can make the startup of rotating shaft and cross bar produce keeps even.These features are that other valves are unexistent, and use said structure moushroom valve sealing surface and sealing seat 7 to be close to, it is according to the elastic force of counterbalance spring simultaneously, and the flow direction that can not flow into valve pocket flows out, and has the function of safety check.
This moushroom valve is provided with filler and loads elastic component (i.e. cluster spring), make valve by normal temperature to high temperature or high temperature to the temperature changing process of normal temperature, and after filler 13 in rotating shaft 5 weares and teares, can both compress filler by auto-compensation, guarantee filler 13 does not leak; In conjunction with spring 6, the static seal leakage that temperature variation causes can be eliminated.
The working principle of moushroom valve involved by the utility model is: driving mechanism drives valve shaft to rotate, and driving mechanism can also be that the connection set such as pneumatic or electronic is connected with slewing gear, the unlatching of driving valve or closedown.Make driver part with in axle for the center of circle rotates, its movement locus is arc-shaped, and dress moushroom valve on the driving part produces displacement thereupon, makes moushroom valve 4 away from fluid passage 2, makes the inlet pipe mouth 10 of fluid passage unobstructed, thus reaches valve opening and close.Rotating shaft filler elastic member is contained in upper valve body axis hole and ensures filler energy tight seal, and the counterbalance spring of moushroom valve ensures there are enough sealing forces with valve base chamber.
For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its framework form can be flexible and changeable; just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that claims of being submitted to by the utility model are determined.
