Description
Technical field
The fixture fields such as valve body class are the utility model is related to, are specially a kind of sealing knot of ball valve pulling force component and sealing shroud
Structure.
Background technology
Ball valve is driven for opening and closing element (sphere) by valve rod, and the valve to rotate around ball valve axis.Also can be used for flowing
The adjusting and control of body, and multi-pass ball valve not only can flexibly control interflow, shunting and the switching of flow direction of medium on pipeline,
It also can close any passage at the same time and make two other passage be connected.
The Starting mode of traditional electrical ball valve works for motor alone pulling force component, and traditional pulling force component
It is the mode of increase sealing ring between sealing shroud, this mode resistance is big, and rubber can be expanded in gas-time length, cause resistance
Greatly increase, pulling force component can be caused not act.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide the sealing structure of a kind of ball valve pulling force component and sealing shroud
The problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical solution：A kind of ball valve pulling force component and sealing shroud
Sealing structure, including ball valve pulling force component and ball valve sealing set, it is characterised in that：The ball valve pulling force component is set in the ball
In valve sealing shroud, the ball valve sealing set bottom is inwardly provided with protrusion, the ball with the ball valve pulling force component touch position
Valve pulling force component overall diameter is consistent with ball valve sealing set bottommost interior diameter.
Through the above technical solutions, ball valve pulling force component and ball valve sealing set are sealed by protrusion, more flexibly, and
If rubber because gas-time length cause expansion after, will not be stuck by pulling force component and cause ball valve can not proper motion.
Preferably, it is described raised to be integrally formed with the ball valve sealing set.
Preferably, perforation is offered at the top of the ball valve pulling force component, screw thread is offered on the perforation inner wall.
Through the above technical solutions, the screw thread opened up is used for the screw rod that fixed insertion connects motor, carried for pulling force component
For power.
Preferably, the ball valve pulling force component bottom is provided with pulling force piece.
Preferably, the pulling force piece is integrally formed with ball valve pulling force component.
Preferably, the ball valve sealing set is rubber material.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in structure, ball valve pulling force component
Cover with ball valve sealing and sealed by protrusion, more flexibly, and if rubber because gas-time length causes expansion after, will not general
Pulling force component is stuck and causes ball valve can not proper motion.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Refering to Figure 1, the mode in figure is deposited, resistance is big, and O-ring can be expanded in gas-time length, cause resistance to increase
Greatly, last stuck, traditional pulling force resistor can not act.
As shown in Figures 2 and 3, the utility model provides a kind of technical solution：A kind of ball valve pulling force component and sealing shroud
Sealing structure, including ball valve pulling force component 1 and ball valve sealing set 2, it is characterised in that：The ball valve pulling force component 1 is set in institute
State in ball valve sealing set 2, the ball valve sealing covers 2 bottoms and is inwardly provided with protrusion with 1 contact position of ball valve pulling force component
3,1 overall diameter of ball valve pulling force component is consistent with the ball valve sealing 2 bottommost interior diameters of set.
Through the above technical solutions, ball valve pulling force component 1 and ball valve sealing set 2 are sealed by protrusion 3, it is more clever
It is living, and if rubber because gas-time length causes expansion after, will not be stuck by pulling force component and cause ball valve can not proper motion.
Further, described raised 3 it is integrally formed with ball valve sealing set 2.
Further, the top of ball valve pulling force component 1 offers perforation, and screw thread 4 is offered on the perforation inner wall.
Through the above technical solutions, the screw thread 4 opened up is used for the screw rod that fixed insertion connects motor, carried for pulling force component
For power.
Further, 1 bottom of ball valve pulling force component is provided with pulling force piece 5.
Further, the pulling force piece 5 is integrally formed with ball valve pulling force component 1.
Further, the ball valve sealing set 2 is rubber material.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in structure, ball valve pulling force component
1 and ball valve sealing set 23 sealed by protrusion, more flexibly, and if rubber because gas-time length causes expansion after, no
Can pulling force component 5 is stuck and cause ball valve can not proper motion, the occupation mode of the utility model is in traditional electrical ball valve
The occupation mode of the occupation mode of pulling force component, i.e. motor drive screw rod to rotate, and screw rod is inserted into screw thread, wherein screw thread and spiral shell
Bar matches, and the ball valve core rotation of ball valve is driven with back pull component.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from the principle of the utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
