Description
Technical field
The utility model relates to a kind of valve, more particularly, relates in particular to a kind of portable sealed valve.
Background technique
In the use of all kinds of valves, being of wide application of ball valve and butterfly valve.It has advantage simple in structure, that switch is rapid, rate of fault is low.They all realize switch for 90 ° through spinning ball or butterfly plate.People use feedack down according to experience of using and special operation condition in long-term using process, on the basis of known advantage, have higher requirement.Main purpose is to realize the requirement of accordingly " low wearing and tearing, low-loss, light moment of torsion, long lifetime, environmental protection and energy-conservation " etc.When under low temperature, high temperature, high pressure, particle and powder medium, using especially, hope that more urgently its usage requirement is satisfied in the improvement of structure.Expansion along with hard seal ball valve, butterfly valve are used is reducing the wearing and tearing that seal between paying, and the moment of torsion that needs when reducing switch prolongs the working life of valve etc., has urgent practical use equally.The sealing of ball valve and butterfly valve is paid and is had not enough place; Main following several aspects: the long-term enclasping type of (1) sealing surface of seat and spheroid or butterfly plate is fitted; Valve seat (soft seal) material is converted into plastic deformation by resiliently deformable easily, and As time goes on, sealing usefulness reduces.(2) in frequent switching process, sealing surface of seat and spheroid or butterfly plate are in friction all the time, are easy to damage sealing surface, influence working life.(3) when pipeline medium is particle, powder, some medium is easy to adhere on the sealing surface, strengthens friction and resistance during rotation, in closing closed procedure, because passage is more and more narrower and small, and swiftly flowing medium, also easy erosion sealing surface of seat influences working life.(4) because sealing surface of seat and spheroid or butterfly plate are normal contact conditions, thus in the valve switch process in requisition for bigger switch moment, will be more obvious for high pressure, this situation of large bore valves.Be directed against under the situation of above-mentioned deficiency, the method that generally adopts at present is that butterfly valve is designed to two eccentric, three off-centre, though can solve some problems, has increased manufacture difficulty.Ball valve design has guiding ball valve, eccentric semi-spherical ball valve, elastic expansion-sleeve spherical ball valve or the like, and these improvement make product structure complicated, and profile increases, and technology difficulty strengthens, and manufacture cost increases.Because also there are wearing and tearing in these new structure key elements in operation process, be easy to damage, and have restricted the working life of valve conversely again.
The model utility content
The purpose of the utility model is the deficiency to above-mentioned existing technology, and a kind of compact structure, easy to use and effective portable sealed valve are provided.
The technological scheme of the utility model is achieved in that a kind of portable sealed valve, comprises valve body, in valve body, is provided with spool; Wherein said valve body is provided with the slide and movable valve base that matches with spool; On valve body, be provided with positioning groove, described slide and movable valve base is movably arranged in the positioning groove, and slide and movable valve base cooperates with positioning groove and is formed with airtight pressure chamber; The pressure chamber is connected with the external pressure source pipeline, through pressure-driven slide and movable valve base is being moved near spool with between away from spool.
In the above-mentioned a kind of portable sealed valve, described slide and movable valve base is an elastic component, and elastic component cooperates the airtight pressure chamber of formation with positioning groove, in the pressure chamber, be provided with first through hole that is connected with the external pressure source pipeline; When boost pressure in the pressure chamber, elastic component cooperates the formation sealing surface towards the expansion of spool direction and with spool; When the pressure in the pressure chamber was discharged, elastic component shrank and separates with spool.
In the above-mentioned a kind of portable sealed valve, described slide and movable valve base constitutes with the driving raised line that is arranged on the mobile seat by moving seat; Described positioning groove sidewall is provided with and drives the groove that raised line adapts to; Described pressure chamber forms by moving the seat mating recesses; Described driving raised line is positioned at this pressure chamber, on the pressure chamber's sidewall that drives the raised line both sides, is respectively equipped with second through hole that is connected with the external pressure source pipeline.
In the above-mentioned a kind of portable sealed valve, described mobile seat is provided with first seal ring with the spool opposing end faces.
In the above-mentioned a kind of portable sealed valve, the contacting part between described mobile seat and the positioning groove is provided with second seal ring.
In the above-mentioned a kind of portable sealed valve, described external pressure source is a source of compressed air.
The utility model through slide and movable valve base, cooperates with spool after adopting said structure, realizes the sealing of movable type, externally under the cooperation of pressure source and pressure chamber, when spool need be opened, removes valve seat earlier, again rotational valve core that is:; When spool needed semi-closure, first rotational valve core was to close stance, and slide and movable valve base to close stance cooperates the formation sealing surface with spool again.Can realize the nothing wearing and tearing opening and closing of spool like this, the working life that can improve valve greatly, the effect of assurance sealing simultaneously,
