Description
Technical field
The utility model relates to a kind of stop valve, particularly relates to a kind of antidetonation stop valve, belongs to valve field.
Background technique
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve; The open-shut device of stop valve is the flap of stopper, and sealing surface is plane or the extra large conical surface, and flap is along the center line moving linearly of valve seat.The forms of motion of valve rod has lifting rotation rod-type, can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Therefore, such stop valve valve that dams is suitable as and cuts off or regulate and throttling use very much.Valve rod due to such valve open or shutoff stroke relatively short, and there is cutting function very reliably, again due to the change of valve seat port and the stroke direct proportionality of flap, be very suitable for regulating flow.
But, in actual motion using process, connecting tube and stop valve are laid and are arranged on different use scenes, on-the-spot for the use larger in shockproofness, stop valve can be caused under constantly shaking to affect its properties, such as sealability, load performance etc., thus the shortening causing working life.
Model utility content
Main purpose of the present utility model is, overcomes deficiency of the prior art, provides a kind of antidetonation stop valve of new structure, is specially adapted to the larger use of shockproofness on-the-spot.
Technical problem to be solved in the utility model be to provide structure simple, easy to make, use reliable, practical antidetonation stop valve, not only properties still can keep good result having under vibrations, and there is good elastic performance and damping capacity, realize absorbing, vibration isolation and noise reduction; Adopt classification antidetonation simultaneously, be applicable to resistance to compression and the tension requirement of different demand, have the value in industry.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of antidetonation stop valve, comprise valve body, valve gap, valve rod and handle, described valve rod is provided with flap, vertical screw is provided with bottom the excircle of described valve body, shown vertical screw is set with elastic bracket, metal-rubber spring ring and fitting seat successively, the end of described vertical screw is connected with floating spiral, and described floating spiral is positioned on pedestal; Match bottom the end face of described elastic bracket and the excircle of valve body, described metal-rubber spring ring card is pressed between elastic bracket and fitting seat.
The utility model is set to further: the fitting surface that described vertical screw contacts with metal-rubber spring ring is provided with the distortion groove be pressed into for metal-rubber spring ring card.
The utility model is set to further: at the bottom of described fitting seat comprises and sidewall, and contact with metal-rubber spring ring bottom surface at the bottom of described seat, described side walls enclose lives metal-rubber spring ring.
The utility model is set to further: the fitting surface contacted with metal-rubber spring ring bottom surface at the bottom of described seat is provided with anti-slip veins.
The utility model is set to further: the end of described vertical screw is connected with floating spiral by spring.
The utility model is set to further: the fitting surface that described pedestal contacts with floating spiral is provided with the concavo-convex groove for floating spiral compressive deformation.
Compared with prior art, the beneficial effect that the utility model has is:
By arranging vertical screw in the bottom of valve body excircle, vertical screw arranges classification earthquake-resistant structure, be respectively elastic bracket, metal-rubber spring ring and fitting seat seismic grade Ⅰ, and floating spiral and pedestal seismic grade Ⅰ, improve the anti-seismic performance of stop valve, make the properties of stop valve still can be unaffected at the use scene that shockproofness is larger; And there is good elastic performance and damping capacity, realize absorbing, vibration isolation and noise reduction; Adopt classification antidetonation simultaneously, be applicable to resistance to compression and the tension requirement of different demand.
Foregoing is only the general introduction of technical solutions of the utility model, and in order to clearer understanding technological means of the present utility model, below in conjunction with accompanying drawing, the utility model will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of antidetonation stop valve of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
A kind of antidetonation stop valve as shown in Figure 1, comprise valve body 1, valve gap 2, valve rod 3 and handle 4, described valve rod 3 is provided with flap 5, vertical screw 6 is provided with bottom the excircle of described valve body 1, shown vertical screw 6 is set with elastic bracket 7, metal-rubber spring ring 8 and fitting seat 9 successively, the end of described vertical screw 6 is connected with floating spiral 10, and described floating spiral 10 is positioned on pedestal 11.
Match bottom the end face of described elastic bracket 7 and the excircle of valve body 1, described metal-rubber spring ring 8 card is pressed between elastic bracket 7 and fitting seat 9.The end of described vertical screw 6 is connected with floating spiral 10 by spring 12.
The fitting surface that described vertical screw 6 contacts with metal-rubber spring ring 8 is provided with and blocks for metal-rubber spring ring 8 the distortion groove 61 be pressed into.The fitting surface that described pedestal 11 contacts with floating spiral 10 is provided with the concavo-convex groove 111 for floating spiral 10 compressive deformation.
