Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
As Figure 1-5, the soft sealing gate valve of a kind of cone seal, including valve body 1, valve gap 2, valve rod 3, rubber-coating flashboard 4
And handwheel 5;
Described valve gap is fixedly connected on valve body, and described valve rod, rubber-coating flashboard are arranged at valve gap and valve inner;Described
Valve rod runs through valve gap, and is fixed in valve gap;The top of valve rod is stretched out from the upper end open of valve gap, and is fixedly connected with the hand wheel;
The bottom of valve rod is fixing with rubber-coating flashboard to be connected, it is preferable that the bottom of valve rod is connected with rubber-coating flashboard screw-driven;
The sealing surface of described valve body is tapered;Described rubber-coating flashboard 4 includes skeleton with cone conformation 401 and soft encapsulated layer 402;Cone
The top of shape skeleton is to fix the fixed part being connected with valve rod, and bottom is sealing, and described soft encapsulated layer is coated on taper bone
Frame lower surface, so that the conical seal (contact) face of soft encapsulated layer and valve body forms soft seal.Described soft encapsulated layer 402 is by circular cone
Body 4021 combines with spherical crown portion 4022, and spherical crown portion is connected to the lower end of circular cone body;The tapering of cone is little, spherical crown portion
Spherical in class, with the sealing surface mating shapes of valve inner, good sealing effect, switch valve moment of torsion is little;On described circular cone body
It is additionally provided with spline platform 4023, prevents from sealing lip displacement, strengthen sealing effectiveness.Valve body and the design of Sealing Structure of rubber-coating flashboard
Becoming distinctive cone shape to seal, and the tapering of circular cone is little so that good sealing effect, switch valve moment of torsion is little, thus solves
The problem that common Gate-valve sealing is the tightest.
Described soft encapsulated layer 402 outer surface is convexly equipped with the sealing lip 4024 of a circular arc, and the two ends sealing lip are divided
It is not connected with spline platform.When making pass valve, sealing lip is easier to extruding and is adjacent to valve seat, thus it is close to easily reach splendid pass valve
Envelope effect.After extruding careful envelope lip, whole rubber-coating flashboard conical seal (contact) face begins to be adjacent to valve body sealing surface, thus quickly increases
Big sealing surface area, makes valve can bear higher pressure and is not caused leakage by dielectric breakdown sealing surface.
Described skeleton with cone conformation is the skeleton with cone conformation that copper alloy is made, and described soft encapsulated layer is the EPDM rubber of vulcanizing treatment
Or the soft encapsulated layer that fluorubber is made.Skeleton with cone conformation is copper alloy skeleton, and skeleton with cone conformation appearance conical seal (contact) face arranges one layer
The EPDM rubber layer of vulcanizing treatment, allows soft rubber form soft seal with the conical valve seat of valve body, seals more reliable, and be difficult to mill
Damage, can be durable in use.
Wherein this soft sealing gate valve also includes out checkpost ring 6 and thrust ring 7;Described valve rod 3 is concavely provided with radial groove
301, it is convexly equipped with annular boss 201 in described valve gap 2 axis hole;Described checkpost ring set of opening is located on valve rod, opens the internal ring of checkpost ring
In the radial groove of valve rod, outer shroud is connected on the annular boss of valve gap;Described thrust ring is set on valve rod, and is connected to
Open on the ring of checkpost.Being convexly equipped with agnail portion 701 on described thrust ring 7, this agnail portion fixes and is connected on the inwall of valve gap thus solid
Determine valve rod not come off.The installation method that valve rod is fixed on valve gap is as follows: be stuck on valve rod radial groove by opening checkpost ring
Put in valve gap axis hole together, then load onto thrust ring, then with taper specific purpose tool, thrust ring is washed open so that it is at valve gap axis hole
Interior formation agnail portion, thus reach fixing valve rod and do not come off, more traditional convenient and simple, safe and reliable of this fixed structure.
This soft sealing gate valve also includes sealing shroud the 8, first O-ring seals the 9, second O-ring seals 10 and y-shaped ring
11;Described sealing shroud is set on valve rod, and abuts with valve gap inwall;Described first O-ring seals and the second O-ring seals divide
It is not set on valve rod, and is positioned on internal ring and the outer shroud of sealing shroud.This y-shaped ring is set on valve rod, y-shaped ring
Tail end 111 is connected between valve rod and valve gap, with valve rod and valve gap interference fit, plays dustproof effect;The middle part of y-shaped ring to
Both sides are convexly equipped with forced seal flange 112, play forced seal effect;The jag end 113 of y-shaped ring is connected to the upper of sealing shroud
End, plays self-pressure-sealed effect.Stem shaft envelope is multi-sealed, the forced seal of existing O RunddichtringO;There is again particular design Y type
The dust seal of sealing ring, forced seal, self-pressure-sealed so that what valve rod went out is sealed with multiple protective, prevents from revealing, seals more
Add safe and reliable.
Described valve body 1 is internal be full-bore through type without groove valve flowing channel, flow resistance is little, be not likely to produce turbulent flow, be difficult to heap
Long-pending foreign material.
Described valve body is tightly connected by screw 12 with valve gap.Described screw is preferably hexagon socket cap head screw, such as Fig. 1
Shown in, but it practice, can also be tightly connected by female thread, other fixing connected modes such as external screw thread is tightly connected.Described
Rubber cushion 13 it is provided with between valve body and valve gap.
The connected mode of valve body and pipeline has various ways, as it is shown in figure 1, connect for female thread, but it practice, commonly uses
External screw thread connection, Flange joint, groove is also had to connect.
Taper soft sealing gate valve good seal performance of the present invention, operational torque is little, and resistance to water-flow is low, simple and compact for structure, accounts for
Little with space, easy for installation.Compared with the structure of existing traditional gate valve, it is tight that this gate valve has pass valve, seals reliable, prolonged resistance to
With etc. feature.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
