Abstract
The utility model provides a high-temperature ball valve with a belleville spring. The high-temperature ball valve with the belleville spring comprises a valve body, a front valve seat, a ball body, a valve rod, a rear valve seat, a first sealing ring, a pressing ring and the belleville spring, wherein the valve body is provided with a liquid inlet and a liquid outlet, the ball body is located in an inner cavity between the liquid inlet and the liquid outlet, the top end of the ball body is fixedly connected with the valve rod, the front valve seat is located between one side face of the ball body and the valve body, and the rear valve seat is located between the other side face of the ball body and the valve body. The front valve seat is fixed on the valve body, the first sealing ring and the pressing ring are arranged on the outer circle of the rear valve seat in a sleeved mode, and the belleville spring is arranged between the pressing ring and the valve body. According to the high-temperature ball valve with the belleville spring, the belleville spring is pressed on the valve seat component, so that the belleville spring is pressed after the ball valve is assembled, on one hand, the belleville spring provides initial force for sealing of the valve, and on the other hand, the sealing rings between the valve seats and the valve body are compressed to enable the sealing reliability of the valve seats and the valve body to be higher.
Description
Technical field
The utility model belongs to the ball valve field, is specifically related to a kind of belleville spring and loads high-temperature ball valve.
Background technique
Ball valve due to have fluid resistance little, easy to operate, open and close rapidly, good airproof performance and reliability high, obtained application widely in industries such as petrochemical industry, long-distance transport pipes and urban heat supplyings.Seat material adopts the soft sealing ball valve that is called of teflon (or filled polytetrafluoroethylene), and its serviceability temperature is no more than 200 degree.Seat material adopts that metal makes is called hard seal ball valve or high-temperature ball valve, and its serviceability temperature is higher than 250 degree.At present, high-temperature ball valve on the market the phenomenons such as seal failure, spheroid block easily occur after work a period of time, and this has directly affected the working life of ball valve.
The model utility content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of belleville spring of good seal performance to load high-temperature ball valve.
The utility model is achieved by the following technical solution:
A kind of belleville spring loads high-temperature ball valve, comprise valve body, front valve seat, spheroid, valve rod, rear valve base, the first seal ring, pressure ring and butterfly spring, be provided with liquid entering hole and liquid outlet on valve body, spheroid is in valve body in the inner chamber between liquid entering hole and liquid outlet, the top of spheroid is fixedly connected with valve rod, and front valve seat and rear valve base are arranged at respectively between the bi-side and valve body of spheroid; Front valve seat is fixed on valve body; Be set with the first seal ring and pressure ring on the cylindrical of rear valve base, be provided with belleville spring between described pressure ring and valve body.
Further setting of the present utility model is, is provided with the second seal ring between front valve seat and valve body.
Further setting of the present utility model is, described front valve seat and rear valve base embed in valve body take the valve rod axle center as symmetry center.
Further setting of the present utility model is, described valve body and corresponding part, rear valve base position are provided with a valve body groove, and rear valve base can slide in described valve body groove.
Belleville spring described in the utility model loads high-temperature ball valve, be pressed on valve component by belleville spring, make the rear belleville spring pressurized of ball valve assembling, it provides starting force for valve seal on the one hand, seal ring between compression valve seat and valve body on the other hand, make between valve seat and valve body sealing reliability higher.Valve component slides when the spheroid expanded by heating, and the belleville spring compressive deformation, can effectively avoid spheroid to block akinesia.
Description of drawings
Fig. 1 is the structural drawing that belleville spring described in the utility model loads high-temperature ball valve;
In figure, each label is: valve body 1, front valve seat 3, spheroid 4, valve rod 5, rear valve base 6, the first seal ring 7, pressure ring 8, butterfly spring 9.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of belleville spring to load high-temperature ball valve, comprise valve body 1, front valve seat 3, spheroid 4, valve rod 5, rear valve base 6, the first seal ring 7, pressure ring 8 and butterfly spring 9, be provided with liquid entering hole and liquid outlet on valve body 1, in the inner chamber of spheroid 4 between the interior liquid entering hole of valve body 1 and liquid outlet, the top of spheroid 4 is fixedly connected with valve rod 5, and front valve seat 3 and rear valve base 6 are arranged at respectively between the bi-side and valve body 1 of spheroid 4; Front valve seat 3 is fixed on valve body 1; Be provided with the second seal ring 2 between front valve seat 3 and valve body 1.Be set with the first seal ring 7 and pressure ring 8 on the cylindrical of rear valve base 6, be provided with belleville spring 9 between described pressure ring 8 and valve body 1.
Described front valve seat 3 and rear valve base 6 embed take valve rod 5 axle center as symmetry center in valve body 1, and valve body 1 is provided with a valve body groove with rear valve base 6 corresponding parts, position, and rear valve base 6 can slide in described valve body groove.Rear valve base 6 slides when spheroid 4 expanded by heating, and belleville spring 9 compressive deformations, can avoid spheroid 4 to block akinesia.
In the utility model, rear valve base 6, the first seal ring 7, pressure ring 8 form a valve component, and belleville spring 9 is pressed on valve component.Belleville spring 9 pressurizeds after the ball valve assembling, it provides starting force for valve seal on the one hand, compresses on the other hand the first seal ring 7 of 1 of rear valve base 6 and valve body, makes 1 sealing of valve seat and valve body.
