Abstract
The utility model discloses a ball valve used for a cooling line system, comprising a valve body, an equipping seat equipped on the valve body and is communicated with the valve body, and a valve bar equipped on the equipping seat with one end outgoes the outboard of the valve body, wherein position limiting plates are equipped along the equipping seat, characterized in that the valve bar is equipped with position limiting compensator plates fixed with the around place, the position limiting compensator plates are equipped with around gaps, and the position limiting plates are equipped on the around gaps. Since the position limiting plates equipped on the equipping seat are equipped on the around gaps equipped on the position limiting compensator plates, when the position limiting compensator plates rotates together with the valve bar, the position limiting plates is not easy to make the position limiting compensator plates distortion, thereby ensuring the using stability of the ball valve.
Description
Technical field
The utility model relates to a kind of ball valve, relates in particular to the ball valve that is used for refrigeration pipe system.
Background technique
In refrigeration system, the transmission of coolant need be undertaken by complicated pipelines.In pipe-line system, generally all need to dispose some ball valves, to realize closing and conducting in the coolant transmission course.Ball valve is to rotate in valve body by valve rod dribbling body to realize that when spheroid rotated, the deflection angle when it rotates need have certain restriction in valve body in opening and closing operations.The structure of restriction ball valve deflection angle generally comprises position limit pin of being located on the valve rod and the banking stop of being located on the valve body on the existing ball valve, wherein banking stop and position limit pin are positioned at same cross section, position limit pin is being followed valve rod when rotating together, banking stop can stop the rotation of position limit pin, thereby the spheroid in the valve body is had a qualification effect when rotating.But this ball valve is in the using process of reality, position limit pin occurs because of the people of the operation too quickly phenomenon that bends of exerting oneself through regular meeting, and the control that this can have influence on spheroid aperture in valve body causes the ball valve stability in use poor.In addition, be located at the also more complicated of this limit structure on the ball valve, processing and assembling inconvenience.Moreover, the distolateral end cap that also needs to be threaded of the valve body of existing this ball valve, end cap is with before valve body is threaded, need on both fitting surfaces, apply some anaerobic adhesives, to increase the connectivity robustness between end cap and the valve body, but in the using process of reality, above-mentioned anaerobic adhesive also exists unsettled phenomenon, tightness between end cap and the valve body can not well be guaranteed, and because ball valve vibration in use, can make to occur loosening phenomenon between end cap and the valve body, soundness between the two is poor.
The model utility content
A purpose of the present utility model is at the problems referred to above, and a kind of ball valve that is used for refrigeration pipe system simple in structure, easy for installation, good stability in the closing operation process is provided.
Another purpose of the present utility model is: a kind of have good connectivity robustness and the bubble-tight ball valve that is used for refrigeration pipe system are provided.
First purpose of the present utility model can realize by following technical proposal: a kind of ball valve that is used for refrigeration pipe system comprises valve body, be located at the fitting seat that communicates with valve body on the valve body, be located at that an end stretches out the valve rod in the valve body outside in the fitting seat, the fitting seat upper edge is provided with banking stop, it is characterized in that, on described valve rod, be provided with and its circumferentially fixing spacing shim, this spacing shim is provided with circumferential breach, and described banking stop is arranged in described circumferential breach.Shape with the spacing shim touching position on the valve rod is generally prism, and spacing shim is provided with the hole that matches with this prism, and spacing shim is socketed on this prism.And described circumferential breach generally is located at the outside on the spacing shim circumferencial direction, and set banking stop is arranged in this circumferential breach on the fitting seat.Spacing shim is being followed valve rod when rotating together, and banking stop reaches the purpose that stops valve rod to rotate by the rotation that stops spacing shim.
At the ball valve that originally is used for refrigeration pipe system, described banking stop is two, and it is arranged on the fitting seat symmetrically.Correspondingly, also be provided with two symmetrically arranged circumferential breach on the described spacing shim.
At the ball valve that originally is used for refrigeration pipe system, described valve rod is provided with sealing gasket, and sealing gasket is positioned at the inboard of described spacing shim, also is provided with the locking nut that is threaded on the valve rod in the outside of spacing shim.The sealing gasket that is provided with can guarantee the sealing between fitting seat and the valve rod.
At the ball valve that originally is used for refrigeration pipe system, on described valve rod, be provided with the compress gasket of a taper, the microcephaly of this compress gasket holds roof pressure distolateral at described sealing gasket.The compress gasket of taper can the crush seal pad under the effect of locking nut, makes sealing gasket produce certain radial deformation, thereby further improves the sealability between fitting seat and the valve rod, and sealing gasket can be made convenient size of installing.
Realize the technological scheme of second purpose of the utility model: described valve rod links with the spheroid of being located in the valve body, in the distolateral end cap that is provided with of spheroid, is provided with the silver soldering layer of a ring-type between this end cap and the valve body on valve body.Weld by silver soldering between valve body and the end cap, silver soldering is high than the stability of anaerobic adhesive, can be because of sex change does not take place in Effect of Environmental, help guaranteeing tightness and soundness between end cap and the valve body.
Compared with prior art, the beneficial effects of the utility model are:
1, with the comparing of existing ball valve, replace position limit pin with spacing shim in this ball valve, spacing shim is when following that valve rod rotates and contacting with set banking stop on the fitting seat, its stress performance will be got well with respect to position limit pin, spacing shim is not yielding, helps guaranteeing the stability in use of this ball valve.
2, replace position limit pin with spacing shim, make that also the corresponding construction on the ball valve is simple, compactedness is good, and be convenient to assembling.
3, weld together by silver soldering between the valve body of ball valve and the end cap, soundness and air-tightness access assurance between valve body and the end cap.
Description of drawings
