Description
Technical field
The present invention 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 has been regulated by the combination of ball valve and needle-valve.First staff makes degree of vacuum and the needed degree of vacuum of manufacturing mechanism as possible by adjusting ball valve, thereby and then is regulated and reached needed degree of vacuum by needle-valve.But sometimes at metering pin valve final vacuum degree, also do not reach desirable state, illustrate that the adjusting existing problems of previous ball valve need regulate ball valve to make degree of vacuum reach perfect condition again.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 those skilled in the art's technical problem urgently to be resolved hurrily.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of Novel conical surface sealed-regulating valve device is provided.
The present invention is for achieving the above object, by the following technical solutions: a kind of Novel conical surface sealed-regulating 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, bottom concaves, for conical surface convex shape, on its convex shape, top is longitudinally provided with aperture around, and aperture laterally runs through pressure regulator valve body sidewall, major axis runs through pressure regulation valve body, and wherein the major axis 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 to be enclosed within pressure regulator valve base A upper, be fixedly connected with.
The below of the round nut that described and major axis are coaxial is provided with square nut and spring.
Described tapering spool is in pressure regulation valve body lower portion conical surface convex shape, and the sealing that overlaps with it.
Described pressure regulator valve base A is enclosed within on pressure regulation valve body, is fixedly connected with.
Described tapering spool is coaxial with major axis, by hexagon nut, is fixed.
Described spring housing is on major axis, and its one end and square nut are close to, the bottom of the other end in pressure regulation valve body hollow circular cylinder.
The present invention, by the vacuum conditions mode of existing ball valve and needle-valve two valves use, makes the vacuum breaker of single valve regulated into.Vacuum breaker adopts the mode of conical surface seal, can solve like this difficulty of existing valve body when vacuum conditions, can guarantee again the stability that degree of vacuum regulates.
Conical surface seal modulating valve is to be sealed and regulated by the conical surface between tapering spool and pressure regulation valve body, on major axis in the middle of tapering spool is fixed on, the connection of pressure regulation valve gap and major axis is simultaneously fixed, the inner-cavity structure of valve body is more special, so just can guarantee that square nut is relatively fixing, then by adjust the seat of square nut in rotary valve cover.When the position of square nut moves down, spring on major axis can tighten up under the driving of square nut, can be to elastic force making progress of square nut, and square nut and major axis are scyewed joint, tapering valve body and major axis are fixed simultaneously, tapering spool has also had the pulling force making progress like this, thereby makes the conical surface of tapering spool and pressure regulation valve body contact tighter.Otherwise while moving on the position of square nut, the conical surface of tapering spool and pressure regulation valve body contacts and can reduce.Conical surface seal modulating valve is exactly that the rotation pressure regulation valve gap of being open to the custom is adjusted tapering spool and contact with the conical surface of pressure regulation valve body, thereby reaches the effect of adjusting degree of vacuum.Secondly the sealing due to the conical surface is to be controlled by the tension force of spring, so when pressure regulation valve gap is compressed downwards, tapering spool will be completely separated with pressure regulation valve body, the degree of vacuum in instrument and equipment reduces rapidly.
The present invention is simple and reasonable, can be applicable to the various extrusion equipments that degree of vacuum had to 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.

Embodiment
A kind of Novel conical surface sealed-regulating valve device as shown in Figure 1, Figure 2, Figure 3 shows, it comprises pressure regulation valve gap 1, pressure regulation valve body 5, tapering spool 7 and pressure regulator valve base, described pressure regulation valve gap 1 is undercut shape, is fixedly connected with round nut 2 with major axis; Described pressure regulation valve body 5 tops are hollow circular cylinder, bottom concaves, for conical surface convex shape, on its convex shape, top is longitudinally provided with aperture around, and aperture laterally runs through pressure regulation valve body 5 sidewalls, major axis runs through pressure regulation valve body 5, and wherein the major axis in pressure regulation valve body 5 top hollow circuit cylinder body cavitys is provided with square nut 4 and spring 6; Described tapering spool 7 is located at the lower end of major axis; Described pressure regulator valve base comprises pressure regulator valve base A8 and pressure regulator valve base B10, and pressure regulator valve base B10 to be enclosed within pressure regulator valve base A8 upper, be fixedly connected with.
First, pressure regulator valve base B10 of the present invention is screwed down, then the present invention is contained on extrusion equipment and is connected and fixed by pressure regulator valve base A8 and pressure regulator valve base B10, pressure regulation valve gap 1, major axis 3 and tapering spool 7 are relatively-stationary; Secondly, when rotation pressure regulation valve gap 1, square nut 4 moves up and down in the interior meeting of pressure regulation valve body 5, thereby the tension force of spring 6 is changed, the attachment portion sealing of tapering spool 7 and pressure regulation valve body 5 lower ends changes, thereby reach the fine adjustment of degree of vacuum, the trouble while jointly regulating by ball valve and needle-valve before having reduced; Finally, the sealing of the conical surface is to be controlled by the tension force of spring 6, when the reasons such as equipment breaks down are stopped in emergency, when pressure regulation valve gap 1 is compressed downwards, tapering spool 7 is separated fast with pressure regulation valve body 5, degree of vacuum in instrument and equipment reduces rapidly, thereby reaches the most fast the release of degree of vacuum.
