Abstract
The utility model discloses an electric rigidity seal ball valve. The electric rigidity seal ball valve is mainly used for solving the problem that when an existing electric rigidity seal ball valve is closed, a valve core cannot come into completely close contact with a valve seat sealing surface, resulting in instable performance even leakage. The electric rigidity seal ball valve is characterized in that a valve seat (3) is provided with a mounting groove (31), a spring (32) is installed on the bottom of the mounting groove (31), a first graphite sealing ring (33) is arranged on the top end of the spring (32), a push plate (34) is arranged on the outer side of the first graphite sealing ring (33), the outer surface of the push plate (34) is coated with a metal seal coating (341), and the push plate (34) is in fit with a valve core (2). The electric rigidity seal ball valve greatly increases the sealing property of the valve core and the valve seat to effectively prevent leakage.
Description
Technical field
The utility model relates to a kind of ball valve, is specifically related to a kind of electronic hard seal ball valve.
Background technique
At present, electric ball valve, because flow forces is strong, opens and closes rapidly fast, and easy for installation, Placement is more, so using scope is wide; The sealing of electric ball valve is broadly divided into soft seal and two kinds of modes of hard sealing, and relatively with electronic soft sealing ball valve, electronic hard seal ball valve can high temperature high voltage resistant due to it, has larger using scope.Yet owing to being subject to machining accuracy, the factor impact such as service life, during electronic hard seal ball valve valve closing, spool can not with the complete close contact of sealing surface of seat, cause unstable properties even to be revealed.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of electronic hard seal ball valve, while mainly having solved existing electronic hard seal ball valve valve closing, spool due to can not with the complete close contact of sealing surface of seat, the problem that causes unstable properties even to be revealed.
The technological scheme that the utility model adopts is, a kind of electronic hard seal ball valve, comprise valve body, spool, valve seat, valve rod, operating device and driving mechanism, described spool is installed in valve body cavity volume, described valve rod bottom is connected with spool, described valve rod upper end is connected with driving mechanism, described valve seat is installed in valve body cavity volume, it is characterized in that: described valve seat is provided with mounting groove, described mounting groove bottom is provided with spring, described spring top is provided with the first carbon seal ring, the first described carbon seal ring outside is provided with push pedal, described push pedal outer surface scribbles metal sealing coating, described push pedal and spool laminating.
Described push pedal is that Si Tailite alloy is made.
Described metal sealing coating is tungsten carbide coating.
Described valve seat outside is provided with valve gap, is provided with the second carbon seal ring between described valve gap and valve seat.
Described valve gap outside is provided with belleville spring.
The beneficial effects of the utility model are: during valve closing, greatly increased spool and valve base sealing, effectively prevented from revealing.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: if Fig. 1 is in conjunction with as shown in Fig. 2 to 3, a kind of electronic hard seal ball valve, comprise valve body 1, spool 2, valve seat 3, valve rod 4, operating device and driving mechanism 8, described spool 2 is installed in valve body 1 cavity volume, described valve rod 4 bottoms are connected with spool 2, described valve rod 4 upper ends are connected with driving mechanism 8, described valve seat 3 is installed in valve body 1 cavity volume, described valve seat 3 is provided with mounting groove 31, described mounting groove 31 bottoms are provided with spring 32, described spring 32 tops are provided with the first carbon seal ring 33, the first described carbon seal ring 33 outsides are provided with push pedal 34, described push pedal 34 outer surfaces scribble metal sealing coating 341, described push pedal 34 and spool 2 laminatings, under the active force of spring 32, push pedal 34 fits tightly with spool 2, spool 2 and valve seat 3 sealings have greatly been increased, effectively prevent from revealing.
In the utility model, as shown in the figure, described push pedal 34 is made for Si Tailite alloy, and Si Tailite alloy dimensional stability is high, wear-resisting, anti-corrosion, anti-oxidant, guarantees sealing.
In the utility model, as shown in the figure, described metal sealing coating 341 is tungsten carbide coating, tungsten carbide coating hardness is high, wear-resisting, certainly, also can adopt other metal sealing coatings herein, tungsten carbide coating is to optimize to select, and other metal sealing coatings also can be according to actual needs as alternative.
In the utility model, as shown in the figure, described valve seat 3 outsides are provided with valve gap 5, are provided with the second carbon seal ring 6, the second carbon seal ring 6 Wear-resistant, high-temperature resistants between described valve gap 5 and valve seat 3, have guaranteed the stability of sealing.
In the utility model, as shown in the figure, described valve gap 5 outsides are provided with belleville spring 7, compress valve gap 5, and belleville spring rigidity is large, and buffering vibration absorption ability is strong, can bear large load with small deformation, and required installing space is little, for can further guaranteeing sealing herein.
In sum, usefulness of the present utility model is: under the active force of spring 32, push pedal 34 fits tightly with spool 2, has greatly increased spool 2 and valve seat 3 sealings, effectively prevents from revealing.
Embodiment should not be considered as this to use novel restriction, but any improvement of using novel spirit to do based on this, all should be within this uses novel protection domain.
