Structure, the shell are equipped with main body section and elastic position, and the main body section includes water conservancy diversion position and force part, described to lead
In tubular construction in flat structure, the force part, the outside at the water conservancy diversion position is equipped with guide face I, inside at stream position
Centre position and force part one end connect, the shell is T-shaped in the cross section of main body section, the connector be spiral shell
Bolt, connector are equipped with flange, and described connector Guan County is on force part, the center line and casing centerline of the connector
Overlap, it is described elasticity position in tubular construction, the elastic portion bit distribution water conservancy diversion position edge and together with force part
Inside positioned at water conservancy diversion position, the outer surface at the elasticity position and guide face I are coherent, and the elasticity position includes sealing
Position, moulding position, the side of the sealing position is connect with water conservancy diversion position, the other side of the sealing position connects with moulding position
Connect, the sealing position outer surface be equipped with around casing centerline distribution protrusion, the shell high spot largest outside diameter,
The inner surface at the moulding position is equipped with confined planes, shape between the sealing position, moulding position, water conservancy diversion position and force part
At the chamber for accommodating elastic support, for the confined planes towards chamber, the cross section of the chamber is trapezoidal, the chamber
If there are one opening, for the opening towards the region between moulding position and force part, the confined planes arrive force part
For the distance on surface in opening towards above gradually decreasing, the elastic support cross section is also trapezoidal, the elastic support with
Compressive state is placed in chamber, and the elastic support and sealing position, water conservancy diversion position, force part all connect and make sealing
Position, water conservancy diversion position, force part are all squeezed by from elastic support, and through-hole, the pedestal are equipped among the pedestal
It is fixedly connected in moulding position, the pedestal is tightly connected with moulding position, and the flange is in the center line extension side of piston
Upwards between force part and pedestal, one end of the connector is located at the side of pedestal, the pedestal, bullet across through-hole
Property supporter, moulding position and force part between be equipped with accommodate elastic support deformation position cavity.
In the technical scheme, shell is semi-enclosed integral structure, its position that is open is arranged far from and needs filling work
The position of sealing function, the separate position for needing to provide guide functions when washing and cleaning operation are provided when industry, therefore in shell and pedestal knot
Conjunction, which forms the unique connecting portion generated after integral structure, not to be influenced filling operation, does not influence washing and cleaning operation；Surface of shell is
Continuously, seamless structure.So the present invention is migrated using integral housing and connecting portion to reasonable position (inoperative
Region) technical solution, completely eliminate in the prior art because gap be present in health concerns caused by filling job area
The inconvenient problem with cleaning.
The sealed connection relationship that piston and other components are established, is the surface by the other components of piston press, and then shape
At close connection relation, which refers to that interference fit is established between piston and other components, thus generates sealing and connects
The effect connect.The sealing position of shell is the sole site that piston forms sealed connection relationship with other components, close in order to allow
Seal position and other component contacts more closely, sealing position is designed to the most thin position of entire piston wall thickness first, makes close
It seals position and obtains elastic deformation ability；Second, elastic support is mounted in shell, and elastic support is in contraction-like after installation
State and in expansion trend and continual crush seal position deforms outward.Finally, seal member protrudes outward,
Protrusion is tightly pressed against the surface of other components, such as the valve interior surface of filling valve.
The effect of elastic support is to maintain the deformation tendency of sealing position and undertakes outer force effect (external force is mainly
The reaction force of other component feedbacks).Elastic support is not located at enclosure interior with natural expansion mode in the initial state,
But by from sealing position, water conservancy diversion position, force part package action and in be extruded state, it and sealing
Position, water conservancy diversion position, force part closely connect；The effect of chamber for accommodating elastic support is to accommodate elastic support simultaneously
And elastic support is made to deform, it is ensured that elastic support can push sealing position to deform and protrude outward.
The key of control elastic support deformation tendency is the shape of chamber, the confined planes in the technical solution of the application
Effect is not only to ensure that the position of elastic support is restricted, it is often more important that control elastic support has always to close
The trend stretched at position is sealed, achievees the purpose that sealing position is pushed to deform outward.
State is interference fitted when using the piston forces sealing position toward contract, in this way, being pushed on the inside of sealing position
Elastic support so that elastic support deforms, and part is to pedestal, elastic support, moulding after elastic support deformation
Cavity migration between position and force part.Cavity is most important during piston applications, it plays direct buffering elastic
Property supporter deflection effect, to generate interference fit have key effect.
The perfect condition of reciprocating motion of the pistons is to maintain fixed pose, and the centerline parallel of piston is in the movement side of piston
To should avoid the centerline dip of piston in the direction of motion the case where, but the situation can be by many in implementation process
Reason and cause, such as not in place, manufacturing deficiency, component are impaired, manipulating object is unstable etc. is installed.Once there is piston to incline
Oblique situation, in addition to other positions (especially end) of protrusion have the case where being contacted with the surface of other components on shell,
Therefore the frictional force that piston motion is subject to increases.But at this time the protrusion on shell remain to establish with the surface of other components it is close
Envelope connection, that is to say, that sealing position is still in effective working condition.It is moulding in the application in order to eliminate the influence of frictional force
The outer diameter of the main part at position has all been configured to the structure of the outer diameter less than sealing position, in this way at the elastic position of shell
Place forms step structure, and in tilting of the piston, the end of shell can be far from the surface of other components, to avoid piston
It can be by additional frictional force.
Moulding position is the position that shell is connect with pedestal.Interference fit type can be passed through between pedestal and moulding position
It is fixedly connected, can also be fixedly connected by binder.No matter which kind of connection type all has the flexibility at moulding position
Particular requirement, and flexibility depends on the wall thickness degree at moulding position, wall thickness value is bigger, flexibility is poorer, and wall thickness value is smaller, soft
Toughness is better.To make moulding position reach rational flexibility, the wall thickness at the moulding position is designed to be more than sealing position
In the wall thickness of high spot, but still need to the outer diameter for keeping the outer diameter of sealing position to be more than moulding position.
Between moulding position and water conservancy diversion position, sealing position side is linked together with water conservancy diversion position, is close sealing position
The envelope position other side is linked together with moulding position.The flexibility that sealing position is shown than the flexibility at moulding position more
Flexible, sealing position is more more elastic than moulding position.Elastic support easily makes sealing position in the case of pushing sealing position
Outside lateral bend shows as heaving outward in sealing position on shell.Therefore, the deformation behaviour of sealing position is to ensure the work
An important factor for sealed connection relationship that plug can be established with other components.Maximum displacement is obtained by deformation in sealing position
Position should be set to the intermediate region of sealing position by protrusion, can make protrusion and its in the centre position of sealing position
Its component establishes connection relation more closely.Most of all, piston obtains compensation function in high spot after setting in this way,
Because larger displacement ensures that protrusion can obtain outwardly extending reaction mechanism under state of wear by deforming, to
It can be compensated by self-deformation in the case where protrusion is worn.
Pedestal is disc-shaped structure, it is only fixedly connected in its side with moulding position, by being set on the inside of moulding position
The limiting slot of annular is set, and limits thickness of the well width equal to the edge of pedestal；When the edge of pedestal is embedded in limiting slot,
The side of pedestal directly contacts with shell and is limited by shell, and the surface of the pedestal other side just links up and shape with the surface of shell
Integrally.The design of limiting slot can effectively improve the efficiency and installation accuracy of mounting seat.
In order to improve the contiguity of pedestal and shell, the centre of the pedestal is equipped with groove, the groove with it is logical
Hole is connected to, and the force part is embedded in groove.Force part is embedded in groove, and force part and pedestal are established closely
Connection relation；So that being connected between shell and pedestal more securely.The design of flange can equally increase connector and force part with
And the contiguity between pedestal.
As a preference of the present invention, the guide face I is in the shape being made of the side and upper bottom surface of round platform.Guide face I
Structure be conducive to liquid under the effect of gravity to casing peripheral flow and leave piston, it is ensured that guide face I will not accumulate liquid,
Convenient for thorough cleaning piston.
For the purposes of thorough cleaning piston, the pedestal is equipped with guide face II, and the guide face II is in the side of round platform
Shape, the outer surface at the moulding position is coherent with guide face II.
In order to avoid generating the potential situation in gap, make no matter entire piston face is in filling job area or remote
It is all rendered as continuous, seamless feature from filling job area, passes through binder between the edge of the pedestal and moulding position
It is fixedly connected, the outer surface at the moulding position and the outer surface of pedestal are coherent.The binder can be filled up completely shell with
In small gaps between pedestal, the position acquisition where binder by way of the binder of surface of shell is overflowed removing
The surface that can link up with the outside at moulding position, the outer surface of pedestal.The whole surface of piston shows continuous, seamless spy
Sign, completely eliminates the influence in gap.
The present invention uses above-mentioned technical proposal：Filling valve will be lived by being the surface texture of integral type by plunger designs
The plug unique connecting portion in surface is disposed away from the position of filling job area, to ensure piston face with continuous, seamless
Feature be located at the region that material flows through.The clean surface degree of piston can meet the requirement of sterile filling, the use of piston
Field is expanded, and thoroughly avoiding piston face gap influences the use of filling valve.
