Description
Technical field
A kind of valve is the utility model is related to, more particularly to a kind of high intensity shut-off valve.
Background technology
Shut-off valve is also known as pipe valve valve, belongs to forced seal formula valve, so when valve is closed, it is necessary to applies to flap and presses
Power, is not leaked with forced seal face.When medium is by entering valve below flap, the resistance that overcomes required for operating force is valve
The frictional force of bar and filler and the thrust as caused by the pressure of medium, the power of closing valve is bigger than the power of valve opening door, so valve rod
Diameter it is big, the failure of valve rod bending otherwise can occur.
Notification number is that the Chinese patent of CN201925496U discloses a kind of high intensity shut-off valve, it includes valve body, is loaded on
Valve deck on valve body, has a seal in valve body, and body cavity is divided into two parts of influent stream chamber and outflow lumen by this seal,
One valve rod passes through valve deck, and the outer end of valve rod is connected opening tool, and the inner of valve rod is equipped with spool, and spool passes through screw thread and connects with valve rod
Connect, and spool is circumferentially fixed that in valve body, the main body of spool is located in outflow lumen, and have on spool matched close with seal
Front cover, is additionally provided with the guide part playing the guiding role to spool between spool and valve body, guide part is located at the lower section of valve deck, and valve rod
Seal is equipped between valve deck.
Fluid is flowed into valve inner by influent stream chamber in above-mentioned patent, then is flowed by seal to outflow lumen, passes through
Valve rod drives spool mobile towards seal and contradicts on seal, is used for realization and fluid is intercepted;Due to seal court
To the end face of valve rod so that spool needs the pressure for overcoming fluid to produce and fluid matasomatism when being moved towards seal in valve
Active force on core, causes valve rod to be subject to larger active force on valve rod, it is easy to send out valve rod when driving spool movement
Raw failure, so as to influence the service life of shut-off valve.
Utility model content
The purpose of this utility model is to provide a kind of high intensity shut-off valve, which can reduce spool and close
When, the active force that is subject on valve rod, so as to extend the service life of shut-off valve.

Valve, including valve body, the valve rod being arranged on valve body and the runner and spool that are arranged in valve body, are provided with the runner close
Runner is divided into influent stream chamber and outflow lumen two parts, one end direction of the influent stream chamber close to seal by sealing, the seal
Spool is set, and the valve rod drives spool to be moved back and forth along axial realize of valve rod, and the seal is arranged on runner and is located at valve
The position of bar axial direction side can simultaneously be sealed by spool on the move, and the spool is equipped with and moves into influent stream chamber and support
Influent stream chamber is touched back to the bearing member of outflow lumen one side wall.
By using above-mentioned technical proposal, by the side that seal is arranged on to valve rod axial direction so that spool is in direction
When seal moves, the force direction for being subject to fluid to apply it on spool is horizontal direction;Spool on the move drives and holds
Power part is moved towards influent stream chamber, and bearing member is contradicted the one side wall in influent stream chamber back to outflow lumen.And when bearing member contradict into
When flowing chamber, the not completely plugged seal of spool, so as to reduce the active force being subject on valve rod;When the gradual plug for seal of spool
During mouth, the pressure of fluid increases and active force of the fluid matasomatism on valve rod also gradually increases, and acts at this time on valve rod
Active force can be carried jointly by bearing member, so as to reduce the active force being subject on valve rod, extend the service life of shut-off valve.
It is further arranged to:The bearing member is curved towards being equipped with back to the flow direction of fluid relative to the opposite side of spool
Pars convoluta.
By using above-mentioned technical proposal, setting increase bearing member and the influent stream chamber of bending section contradict bearing member one side wall it
Between distance so that bearing member can preferably enter influent stream intracavitary.
It is further arranged to:The bearing member stretches out setting parallel to the two side of valve rod axial direction, the load
The straight slot by bearing member for fluid is offered on part.
By using above-mentioned technical proposal, the two side of bearing member is arranged to outwardly extending mode, increases bearing member
With the contact area between influent stream chamber so that bearing member can realize active force preferably carrying;And used by the setting of straight slot
In the passability for ensureing fluid.
It is further arranged to:The bending section towards being connected with reinforcing rib between the one side of influent stream chamber and spool, it is described plus
Strengthening tendons connects bearing member and is set along the arranged radially of valve rod.
By using above-mentioned technical proposal, the structural strength and load for being used to lift bearing member by the setting of reinforcing rib
Structural strength between part and spool so that bearing member can realize active force preferably carrying stress.
It is further arranged to:Overbank sets and forms an inclination strengthening portion between the reinforcing rib and spool.
By using above-mentioned technical proposal, the connection area between the setting increase reinforcing rib of strengthening portion and spool is tilted,
The active force being subject on reinforcing rib is enabled to realize more quick conduction.
It is further arranged to:The tip position of the seal is obliquely installed towards outflow lumen direction.
By using above-mentioned technical proposal, setting spool by this kind, spool can be right when being moved towards seal
Seal applies the chip hold down power of bigger, so as to fulfill the more preferable sealing between spool and seal.
It is further arranged to:The end face of the seal towards spool is equipped with sealing ring.
By using above-mentioned technical proposal, the setting of sealing ring reduces the gap between seal and spool, so as to reach
Better seal effect.
It is further arranged to:The seal is equipped with the card slot that its disengaging is embedded and limited for sealing ring.
By using above-mentioned technical proposal, sealing ring is fastened in card slot, is used for realization sealing ring consolidating on seal
It is fixed.
In conclusion the utility model has the advantages that:By setting bearing member on spool so that spool exists
During closing seam mouth, active force of the fluid matasomatism on valve rod can be carried jointly by bearing member, thus reduce on valve rod by
The active force arrived, extends the service life of shut-off valve;Bearing member and spool are lifted by setting of the reinforcing rib with tilting strengthening portion
Between structural strength;And the leakproofness between the setting increase spool and seal for passing through sealing ring.
