Description
Technical field
The utility model relates to the filling valve on a kind of filling apparatus.
Background technique
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 connection part of blocked shot 2 this end that valve body 1 is provided with discharge port to its structure; Liquid sealing linkage 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 Placement 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 installation precision of blocked shot, if the centre of sphere of two spheres has the situation of the center line 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 problem to be solved in the utility model improves existing filling valve to there will be the situation that liquid sealing is not tight, there is leakage, object is to provide a kind of filling valve, stuffing box gland and pedestal are connected firmly, seal tight, leakage can not be produced, black box is installed, convenient disassembly, long service life.
For solving above-mentioned existing technical problem, the utility model 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 black box towards one end of reducing, described black box comprises pedestal and parcel and the stuffing box gland be attached to outside pedestal, the sidepiece of described pedestal the part that wraps by stuffing box gland 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 stuffing box gland 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 outer wall 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 tapered collar faces are symmetrical arranged and all in the scope that stuffing box gland 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 stuffing box gland at two taper anchor ring places also reduces to form reduction section gradually, described black box to be contacted at the wall of reducing place by its outer surface 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 stuffing box gland at this place to be out of shape and reduction of service life, allow after stuffing box gland and valve body contact position distortions and have more position to be fitted on sealing surface.By the working position by black box---the position that namely on stuffing box gland, reduction section and valve body contact seal is arranged on taper anchor ring place, can reduce the amount of deformation of stuffing box gland at this position and controlling distortion direction, can extend the working life of stuffing box gland.After stuffing box gland arranges two reduction section, black box two ends are capable of reversing, the replaceable use in black box two ends; Taper anchor ring is for limiting the position of stuffing box gland and controlling the deformation direction of stuffing box gland at this position; Stuffing box gland is attached on pedestal, as stuffing box gland by adhesion, that deadlocked and Shooting Technique is directly injection-moulded in pedestal is first-class, make between stuffing box gland and pedestal, to form compact siro spinning technology relation, unless under stripping state, otherwise stuffing box gland can not opposite base generation relative movement, stuffing box gland good fixing effect.In the utility model, the outer surface 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 flange flange of a week towards the side place of pedestal, the taper anchor ring that the inner side surface of the second annular flange flange is nearest with distance the second annular flange flange parallels, and described stuffing box gland is clipped between the second annular flange flange and pedestal towards one end of cushion block.After cushion block is set, by cushion block, the bottom of stuffing box gland is pressed in pedestal, can reduce on the one hand installing and the distortion of the stuffing box gland that bolt and stuffing box gland spin friction cause in using process, slow down continuous distortion in stuffing box gland Reusability process and peel off between the bottom part stuffing box gland that causes and pedestal; By arranging the second annular flange flange on cushion block, and Parallel Design can be adopted by between the second annular flange flange and the taper anchor ring nearest apart from the second annular flange flange on the other hand, the deformation direction of stuffing box gland can be controlled further.
As preferably, described blocked shot is provided with around pedestal first annular flange flange of a week towards one end end face of pedestal, the taper anchor ring that the inner side surface of described first annular flange flange is nearest with distance the first annular flange flange parallels, and described stuffing box gland is clipped between the second annular flange flange 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 the 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 head of bolt.
Beneficial effect:
