Description
Technical field
The present invention relates to the filling valve on a kind of filling apparatus.
Background technology
Filling valve comprises valve body 1 and blocked shot 2, it is inner that blocked shot 2 is positioned at valve body 1, the mode contacted with face by face between blocked shot 2 with valve body 1 forms liquid sealing annexation, and as shown in Figure 8, valve body 1 is positioned at the connecting portion of blocked shot 2 this end that valve body 1 is provided with discharging opening to its structure; Liquid sealing connection structure described here is made up of the sphere of the sphere on blocked shot, valve inner, and the radius of two spheres is different, therefore forms the connection mode of linear contact lay after contact.Sphere between two different radiis contacts with each other and forms the relation of line connection, and reaches seal request with this, higher to the processing request of sphere; In addition, require harsh to the setting accuracy of blocked shot, if the centre of sphere of two spheres has the situation of the line of centers deviating from blocked shot, the connection tightness degree so between two spheres presents difference at different parts.Just because of this, it is not tight that the filling valve of actual production and processing gained there will be liquid sealing, there is the situation of leakage.
Summary of the invention
Technical matters to be solved by this invention improves existing filling valve to there will be the situation that liquid sealing is not tight, there is leakage, and object is to provide a kind of filling valve, and sealing shroud and pedestal are connected firmly, seal tight, leakage can not be produced, poted assemblies installation, convenient disassembly, long service life.
For solving above-mentioned existing technical matters, the present invention adopts following scheme: a kind of filling valve, comprise valve body and blocked shot, described valve body has inner chamber, described valve body to diminish formation reducing gradually at inner chamber one end place internal diameter, described blocked shot is arranged in inner chamber, described blocked shot is provided with poted assemblies towards one end of reducing, described poted assemblies comprises pedestal and parcel and the sealing shroud be attached to outside pedestal, the sidepiece of described pedestal the part that wraps by sealing shroud is provided with some around the pedestal circumference annular dovetail slot of a week, described annular dovetail slot sets gradually along the axis of pedestal, described sealing shroud is provided with at corresponding annular dovetail slot place the annular protrusion embedded in annular dovetail slot, along pedestal axially from the middle part of pedestal to blocked shot with to the direction that reducing extends, the external diameter of described pedestal is reducing to make the outside wall surface of pedestal form taper anchor ring at this place near one end place of blocked shot with at one end place of close reducing all gradually, two conical ring faces are symmetrical arranged and all in the scope that sealing shroud wraps up, taper anchor ring near one end place of reducing is parallel to the wall of valve body in reducing place, the external diameter of described sealing shroud at two taper anchor ring places also reduces to form reduction section gradually, described poted assemblies to be contacted at the wall of reducing place by its outside face and valve body near the reduction section of reducing one end and realizes coordinating with valve seal.
The effect of annular dovetail slot is fixing seal cover, arch up when preventing the sealing shroud at this place to be out of shape and reduction of service life, allow after sealing shroud and valve body contact position distortions and have more position to be fitted on sealing surface.By the working position by poted assemblies---the position that namely on sealing shroud, reduction section and valve body contact seal is arranged on taper anchor ring place, can reduce the deflection of sealing shroud at this position and controlling distortion direction, can extend the service life of sealing shroud.After sealing shroud arranges two reduction section, poted assemblies two ends are capable of reversing, the replaceable use in poted assemblies two ends; Taper anchor ring is for limiting the position of sealing shroud and controlling the deformation direction of sealing shroud at this position; Sealing shroud is attached on pedestal, as sealing shroud by adhesion, that deadlocked and Shooting Technique is directly injection-moulded in pedestal is first-class, make between sealing shroud and pedestal, to form compact siro spinning technology relation, unless under stripping state, otherwise sealing shroud can not opposite base generation relative motion, sealing shroud good fixing effect.In the present invention, the outside face of reduction section adopts sphere, and can be the face identical with spherome surface, also can be the level and smooth cambered surface being similar to spherome surface.
As preferably, described pedestal is arranged on blocked shot by bolt, described pedestal is provided with cushion block towards between one end and bolt of reducing, described cushion block is provided with around pedestal second annular lip of a week towards the side place of pedestal, the taper anchor ring that the medial surface of the second annular lip is nearest with distance the second annular lip parallels, and described sealing shroud is clipped between the second annular lip and pedestal towards one end of cushion block.After cushion block is set, by cushion block, the bottom of sealing shroud is pressed in pedestal, can reduce on the one hand installing and the distortion of the sealing shroud that bolt and sealing shroud spin friction cause in use procedure, slow down continuous distortion in sealing shroud Reusability process and peel off between the bottom part sealing shroud that causes and pedestal; By arranging the second annular lip on cushion block, and Parallel Design can be adopted by between the second annular lip and the taper anchor ring nearest apart from the second annular lip on the other hand, the deformation direction of sealing shroud can be controlled further.
As preferably, described blocked shot is provided with around pedestal first annular lip of a week towards one end end face of pedestal, the taper anchor ring that the medial surface of described first annular lip is nearest with distance the first annular lip parallels, and described sealing shroud is clipped between the first annular lip and pedestal towards one end of blocked shot.
As preferably, described annular dovetail slot is three, three annular dovetail slots are equally spaced along the axis of pedestal, one of them taper anchor ring be located at annular dovetail slot in the middle part of pedestal and between the annular dovetail slot of pedestal one end, another taper anchor ring is located at annular dovetail slot in the middle part of pedestal and between the annular dovetail slot of the pedestal other end.Three annular dovetail slots and two taper anchor rings spaced apart, locating effect is better.
As preferably, described blocked shot is provided with the first circular groove towards one end end face of pedestal, and described pedestal stretches into the first circular groove towards one end of blocked shot and is radially positioned in the first circular groove.
As preferably, described cushion block is provided with the second circular groove towards one end end face of pedestal, and described pedestal stretches into the second circular groove towards one end of cushion block and is positioned in the second circular groove.
As preferably, be sealed and matched between described cushion block and the bolt cap of bolt.
Beneficial effect:
A kind of filling valve that the present invention adopts technique scheme to provide, by arranging annular dovetail slot on pedestal, arranging the annular protrusion corresponding with annular dovetail slot at sealing shroud inwall, sealing shroud can firmly be connected on pedestal; By arranging the second annular lip on cushion block, the taper anchor ring on the internal face of this second annular lip and pedestal is come together pinch seal cover, and the sealing of this filling valve is tight, does not produce leakage; The replaceable use in the upper and lower two ends of poted assemblies of this filling valve, poted assemblies is installed, convenient disassembly, long service life.
