Summary of the invention
At the deficiency of prior art existence, but the utility model provides the two-way hard seal floating ball valve of a kind of two-way hard seal and good sealing effect.
For achieving the above object, the utility model provides following technological scheme: a kind of two-way hard seal floating ball valve, include power plant, valve body, valve rod, spheroid, described valve body is provided with traffic channel, the upstream of traffic channel is provided with dynamic seal apparatus, this dynamic seal apparatus comprises the valve seat adaptive with spheroid, belleville spring, be located at the gland between valve seat and the belleville spring, described valve seat is provided with Expanded graphite, the downstream of described valve body traffic channel is provided with the dynamic seal apparatus corresponding with the traffic channel upstream, be provided with link between the inwall of valve body traffic channel and the valve seat in the dynamic seal apparatus, constitute valve seat and cooperate with the horizontal slippage of the inwall of valve body traffic channel.
Downstream of valve body traffic channel is provided with the dynamic seal apparatus corresponding with the traffic channel upstream in this, is provided with link between the inwall of valve body traffic channel and the valve seat in the dynamic seal apparatus, constitutes valve seat and cooperates with the horizontal slippage of the inwall of valve body traffic channel.The spheroid both sides that are provided with like this in the rear valve body traffic channel all are provided with dynamic seal apparatus; make it possess the function of two-way hard seal; and valve seat cooperates then and can effectively protect belleville spring with the horizontal slippage of the inwall of valve body traffic channel, and the bearing capacity that prevents belleville spring is excessive and cause damaging.
The utility model further is set to: the link that is provided with between the inwall of described valve body traffic channel and the valve seat is to be located at the short slot on the inwall of valve body traffic channel and to be located on the valve seat and the projection corresponding with short slot.Be provided with buffer space between the sidewall of short slot and the projection on the described valve body traffic channel, the cross section of slightly being longer than projection of short slot cross section.
The link that is provided with between the inwall of valve body traffic channel and the valve seat in this is to be located at the short slot on the inwall of valve body traffic channel and to be located on the valve seat and the projection corresponding with short slot, be provided with buffer space between the sidewall of short slot and the projection on the valve body traffic channel, the cross section of short slot slightly is longer than the cross section of projection.Back projection and valve seat are set so just can slippage in the short slot of valve body traffic channel, has further guaranteed the Security of belleville spring.
The utility model further is set to: described Expanded graphite is sheathed on the extending end of valve seat, one end and valve seat are conflicted, the other end and gland are conflicted, the end that described Expanded graphite and gland are conflicted is " V " font, the conflict end of gland and flexible stone mill also is " V " font, constitutes face seal and cooperates.
Expanded graphite is sheathed on the extending end of valve seat in this, one end and valve seat are conflicted, and the other end and gland are conflicted, and the end that described Expanded graphite and gland are conflicted is " V " font, the conflict end of gland and flexible stone mill also is " V " font, constitutes face seal and cooperates.After back Expanded graphite pressurized was set like this, its both sides then can expand outwardly respectively with " V " font end face, thus better sealing.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the I portion enlarged view of Fig. 1.
Embodiment
As Fig. 1; a kind of two-way hard seal floating ball valve shown in Figure 2; include power plant; valve body 1; valve rod 2; spheroid 3; described valve body 1 is provided with traffic channel 11; the upstream of traffic channel 11 is provided with dynamic seal apparatus 4; this dynamic seal apparatus 4 comprises the valve seat 41 adaptive with spheroid 3; belleville spring 42; be located at the gland 43 between valve seat 41 and the belleville spring 42; described valve seat 41 is provided with Expanded graphite 44; the downstream of described valve body 1 traffic channel 11 is provided with the dynamic seal apparatus 4 corresponding with traffic channel 11 upstreams; be provided with link between the inwall 111 of valve body 1 traffic channel 11 and the valve seat 41 in the dynamic seal apparatus 4; constituting valve seat 41 cooperates with the horizontal slippage of the inwall 111 of valve body 1 traffic channel 11; spheroid 3 both sides that are provided with like this in rear valve body 1 traffic channel 11 all are provided with dynamic seal apparatus 4; medium enters all from any end of valve body 1 can reach sealing; and prevent the wearing and tearing of spheroid 3; and valve seat 41 cooperates then and can effectively protect belleville spring 42 with the horizontal slippage of the inwall 111 of valve body 1 traffic channel 11, and the bearing capacity that prevents belleville spring 42 is excessive and cause damaging.
In the utility model embodiment, the link that is provided with between the inwall 111 of described valve body 1 traffic channel 11 and the valve seat 41 is to be located at the short slot 12 on the inwall 111 of valve body 1 traffic channel 11 and to be located on the valve seat 41 and the projection 411 corresponding with short slot 12, certainly, described link also can be the projection on the inwall 111 of being located at valve body 1 traffic channel 11 and is located on the valve seat 41 and the short slot corresponding with projection, so also be feasible, be provided with buffer space 5 between the sidewall of short slot 12 and the projection 411 on described valve body 1 traffic channel 11, the cross section of short slot 12 slightly is longer than the cross section of projection 411; The buffer space 5 here is the buffer space of belleville spring 42, and what make that pressure can be inexcessive compresses belleville spring 42, and causes the damage of belleville spring 42.
In the utility model embodiment, described Expanded graphite 44 is sheathed on the extending end of valve seat 41, one end and valve seat 41 are conflicted, the other end and gland 43 are conflicted, described Expanded graphite 44 is " V " font with the end that gland 43 is conflicted, gland 43 also is " V " font with the conflict end of Expanded graphite 44, constituting face seal cooperates, the end that Expanded graphite 44 is connected with gland 43 be arranged to " V " font be then since medium when any port of valve body 1 enters, pressure can enter from Expanded graphite 44 " V " word end, thereby Expanded graphite 44 is compressed to both sides, guarantee its sealing; Certainly, also the one end can be arranged to the inclined-plane, it is not obvious just sealing effect to be set like this, so the utility model adopts the former.
