Description

A kind of stop valve
Technical field
The present invention relates to a kind of stop valve, belong to valve field.
Background technology
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve;The opening and closing element of stop valve is the flap of stopper, and sealing surface is plane or the sea conical surface, and flap is for linear motion along the centrage of valve seat.The forms of motion of valve rod has lifting rotation rod-type, can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Therefore, such stop valve valve that dams is highly suitable as cutting off or regulating and throttling use.Due to the valve rod of such valve, to be turned on and off stroke relatively short, and has cutting function very reliably, again due to change and the stroke direct proportionality of flap of valve seat port, is very suitable for being adjusted flow.
But, during actual motion uses, when medium is by when entering valve below flap, the resistance overcome required for operating physical force, be valve rod and filler frictional force with by thrust produced by the pressure of medium, so the power that there is the force rate valve opening door of closing valve wants big difference, therefore require that the diameter of valve rod wants big, the fault of valve rod bending otherwise can occur;And, in longtime running, fluid resistance is big, and sealing reliability reduces.
Summary of the invention
Present invention is primarily targeted at, overcome deficiency of the prior art, the stop valve of a kind of new structure is provided, the medium pressure to flap during closing valve is reduced by setting up parts, reduce flap pressurized excessive impaired, flap is made to engage sealing with valve seat smoothly, while extending the flap life-span, lift-off seal performance.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of stop valve, including valve body, valve gap, valve rod and handle, it is provided with flap on described valve rod, the described vertical shape of flap end is provided with closure member, described closure member is connected to close medium flow channel one end edge of flap end, and the axial length dimension of described closure member is less than the diameter dimension in the medium flow channel cross section extended with closure member axial direction;Described closure member is inverted cone cylinder, and the dome face of described inverted cone cylinder is run through in the circular groove of flap end, and the cone vertex (vertices) of described inverted cone cylinder is free end.
The present invention is further arranged to: the periphery of described inverted cone cylinder is provided with impeller.
The present invention is further set to: described inverted cone cylinder is the hollow rounding vertebral body of periphery Openworks shape.
The present invention is further set to: described impeller is uniformly distributed.
The present invention is further set to: described impeller is elastic impeller.
The present invention is further set to: described inverted cone cylinder and impeller are one-body molded.
Compared with prior art, the device have the advantages that and be:
By arranging these parts of closure member at the vertical shape of flap end, make stop valve during closing valve, closure member plays the effect lived by dielectric impedance in advance, thus reduce the medium entered below the flap pressure to flap, reduce flap pressurized excessive and may cause to damage, strengthen flap simultaneously and engage the smooth operation sealed with valve seat, extend the flap life-span, and lift-off seal performance, so use reliable, practical.
Foregoing is only the general introduction of technical solution of the present invention, and in order to be better understood upon the technological means of the present invention, the invention will be further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of stop valve of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of stop valve, including valve body 1, valve gap 2, valve rod 3 and handle 4, it is provided with flap 5 on described valve rod 1, the described flap 5 vertical shape of end is provided with closure member 6, described closure member 6 is connected to close medium flow channel one end edge of flap 5 end, and the axial length dimension of described closure member 6 is less than the diameter dimension in medium flow channel 10 cross section extended with closure member 6 axial direction.
Wherein, described closure member 6 is inverted cone cylinder, and the dome face of described inverted cone cylinder is run through in the circular groove of flap 5 end, and the cone vertex (vertices) of described inverted cone cylinder is free end.
Further, the periphery of described inverted cone cylinder is provided with impeller 61;Described impeller 61 is equally distributed elastic impeller.
Further, described inverted cone cylinder is the hollow rounding vertebral body of periphery Openworks shape;Described inverted cone cylinder and impeller 61 are one-body molded.
The innovative point of the present invention is, by arranging these parts of closure member at the vertical shape of flap end, make stop valve during closing valve, closure member plays the effect lived by dielectric impedance in advance, thus reducing the medium entered below the flap pressure to flap, reduction flap pressurized is excessive and may cause to damage, and strengthens flap simultaneously and engages the smooth operation of sealing with valve seat, extend the flap life-span, and lift-off seal performance;Have simple in construction, easy to make, use reliable, practical advantage.
The above, it it is only presently preferred embodiments of the present invention, not the present invention is made any pro forma restriction, although the present invention is disclosed above with preferred embodiment, but it is not limited to the present invention, any those skilled in the art, in the range of without departing from technical solution of the present invention, when the technology contents of available the disclosure above makes a little change or is modified to the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solution of the present invention, any simple modification above example made according to the technical spirit of the present invention, equivalent variations and modification, all still fall within the range of technical solution of the present invention.
