Abstract
This invention relates to a ball valve with compact structure and fine tightness, which contains valve body with valve base, valve rod and tetra fluoride pad, wherein the elastic matter set between valve base and tetra fluoride which containing support ring and butterfly spring, said support ring inserted in the inner hole of tetra fluoride, the back surface connected with support and front surface connected with valve base. Said invention has compact structure and fine tightness.
Description
Technical field
The invention belongs to valve, relate in particular to the ball valve of a kind of compact structure, good airproof performance.
Background technique
The spheroid of the ball valve that uses on the market is connected with the phenyl tetrafluoride pad anchor ring, because extended immobilization connects, causes phenyl tetrafluoride pad to be crushed to death easily, causes it to follow the string, and causes ball valve to reveal, fit badly, the switch difficulty, even can not seal.In order to prevent that phenyl tetrafluoride pad from keeping elasticity, bigbore ball valve is equal portion spring between valve seat and phenyl tetrafluoride pad, is not crushed to death to keep phenyl tetrafluoride pad.But can't solve this technical problem since the midium or long term at small-bore ball valve.
Summary of the invention
The object of the present invention is to provide the ball valve of a kind of compact structure, good airproof performance, solved the technical problem that phenyl tetrafluoride pad is crushed to death, the sealability of ball valve is strengthened, switch is light, is not easy to leak.
For achieving the above object, by the following technical solutions: a kind of ball valve, comprise valve body, valve rod, spheroid and the phenyl tetrafluoride pad of being with valve seat, it is characterized in that: between valve seat in spheroid and the phenyl tetrafluoride pad elastic floating device is housed, elastic floating device comprises elastic element and supporting element, places successively between valve seat and the phenyl tetrafluoride pad.
Described elastic floating device comprises bracing ring and butterfly spring, and described bracing ring is plugged in the phenyl tetrafluoride pad endoporus, and the butterfly spring back side and bracing ring touch, and its front is connected with valve seat.
Described elastic floating device places the ball valve spheroid by importing and exporting both sides.
Described butterfly spring can adopt two back-to-back butterfly springs staggered relatively to place between bracing ring and the valve seat.
Beneficial effect of the present invention: the ball valve of compact structure, good airproof performance, solved the technical problem that phenyl tetrafluoride pad is crushed to death, the sealability of ball valve is strengthened, switch is light, is not easy to leak.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the scheme of installation of phenyl tetrafluoride pad among Fig. 1, bracing ring and butterfly spring.
Embodiment
Accompanying drawing is embodiments of the invention, describes the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of ball valve comprises valve body 1, valve rod 2, spheroid 3 and the phenyl tetrafluoride pad 4 of being with valve seat, it is characterized in that: between valve seat 1-1 in spheroid and the phenyl tetrafluoride pad 4 elastic floating device is housed.Described elastic floating device comprises bracing ring 5 and butterfly spring 6, and described bracing ring is plugged in the phenyl tetrafluoride pad endoporus, and the butterfly spring back side and bracing ring touch, and its front is connected with valve seat.Described elastic floating device places the ball valve spheroid by importing and exporting both sides.Described butterfly spring also can adopt two back-to-back butterfly springs staggered relatively to place between bracing ring and the valve seat, makes its elasticity bigger.Bracing ring is plugged in the phenyl tetrafluoride pad endoporus, the butterfly spring back side contacts with the support astragal, its front is connected with valve seat, the butterfly spring plays elastic reaction, make the sealing of spheroid and phenyl tetrafluoride pad be quick condition, prevent that phenyl tetrafluoride pad is crushed to death, thereby can guarantee that the ball valve sealing performance improves, be not easy to reveal, and switch is light.This elastic floating device goes for the ball valve of various models and specification.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technological scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (4)
1, a kind of ball valve, comprise valve body, valve rod, spheroid and the phenyl tetrafluoride pad of being with valve seat, it is characterized in that: between valve seat in spheroid and the phenyl tetrafluoride pad elastic floating device is housed, elastic floating device comprises elastic element and supporting element, places successively between valve seat and the phenyl tetrafluoride pad.
2, ball valve according to claim 1 is characterized in that: described elastic floating device comprises bracing ring and butterfly spring, and described bracing ring is plugged in the phenyl tetrafluoride pad endoporus, and the butterfly spring back side and bracing ring touch, and butterfly spring front is connected with valve seat.
