Description
Technical field
The utility model relates to a kind of control valve device, more precisely a kind of novel seal control valve device for extruder degree of vacuum is regulated.
Background technique
Current, many different extruder manufacturing mechanisms to degree of vacuum require differently, and existing vacuum-ness regulator is regulated by ball valve and needle-valve combination and is finished.At first the staff makes degree of vacuum and the needed degree of vacuum of manufacturing mechanism as possible by regulating ball valve, thereby and then regulates by needle-valve and to reach needed degree of vacuum.But sometimes also do not reach desirable state at metering pin valve final vacuum degree, the adjusting existing problems that previous ball valve then is described need be regulated ball valve again makes degree of vacuum reach perfect condition.So again and again not only lost time to lavish labor on but also in the difficulty that has virtually increased vacuum conditions, therefore this technological deficiency becomes the technical problem that those skilled in the art need to be resolved hurrily.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of spring that utilizes to realize the conical surface seal control valve device.
The utility model is for achieving the above object, by the following technical solutions: a kind of spring that utilizes is realized the conical surface seal control valve device, it comprises pressure regulation valve gap, pressure regulation valve body, tapering spool and pressure regulator valve base, and described pressure regulation valve gap is undercut shape, is fixedly connected with round nut with major axis; Described pressure regulation valve body top is hollow circular cylinder, the bottom concaves, be conical surface convex shape, vertically be provided with aperture on its convex shape around the top, and aperture laterally runs through the pressure regulator valve body sidewall, major axis runs through the pressure regulation valve body, and the major axis that wherein is in the hollow circuit cylinder body cavity of pressure regulation valve body top is provided with square nut and spring; Described tapering spool is located at the lower end of major axis; Described pressure regulator valve base comprises pressure regulator valve base A and pressure regulator valve base B, and pressure regulator valve base B is enclosed within on the pressure regulator valve base A, is fixedly connected with; Described tapering spool is in the pressure regulation valve body lower portion conical surface convex shape, and overlaps sealing with it; Described tapering spool is coaxial with major axis, is fixed by hexagon nut; Described spring housing is on major axis, and one end and square nut are close to, and the other end is in the bottom of pressure regulation valve body hollow circular cylinder.
The below of the round nut that described and major axis are coaxial is provided with square nut and spring.
Described pressure regulator valve base A is enclosed within on the pressure regulation valve body, is fixedly connected with.
The utility model makes the vacuum conditions mode of existing ball valve and needle-valve two valves and usefulness the vacuum breaker of single valve regulated into.Vacuum breaker adopts the mode of conical surface seal, can solve so the existing difficulty of valve body when vacuum conditions, can guarantee again the stability that degree of vacuum is regulated.
The conical surface seal modulating valve is to seal adjusting by the conical surface between tapering spool and the pressure regulation valve body, on the major axis in the middle of the tapering spool is fixed on, simultaneously the pressure regulation valve gap is connected connection and is fixed with major axis, the inner-cavity structure of valve body is more special, so just can guarantee that the square nut is relatively fixing, then by in rotary valve cover, adjusting the seat of square nut.When the position of square nut moves down, spring on the major axis can tighten up under the driving of square nut, can be to elastic force that makes progress of square nut, and square nut and major axis are scyewed joint, tapering valve body and major axis are fixed simultaneously, the tapering spool has also had the pulling force that makes progress like this, thereby makes the conical surface of tapering spool and pressure regulation valve body contact tighter.Otherwise when moving on the position of square nut, the conical surface of tapering spool and pressure regulation valve body contacts and can reduce.The conical surface seal modulating valve is exactly that the conical surface that rotation pressure regulation valve gap adjusts tapering spool and pressure regulation valve body of being open to the custom contact, thereby reaches the effect of adjusting degree of vacuum.Secondly because sealing of the conical surface is to be controlled by the tension force of spring, so when the pressure regulation valve gap compressed downwards, the tapering spool will separate fully with the pressure regulation valve body, the degree of vacuum in the instrument and equipment reduces rapidly.
The utility model is simple and reasonable, can be applicable to the various extrusion equipments that degree of vacuum had requirement; Both solved the difficulty that operator regulate extrusion production equipment degree of vacuum, the time of having saved has been improved work rate again simultaneously.
