Abstract
The utility model discloses a kind of high pressure single seat spool stem structures, including spool and valve rod, are connected with each other between the spool and the valve rod by valve core housing.One end of the valve rod has external screw thread, and one end of the valve core housing has internal screw thread, and the valve core housing is socketed on the valve rod by screw thread.The other end of the valve core housing has card interface, and the outer wall of the spool is arranged at the card interface.The internal diameter of the trapezoidal shape of card interface and then the card interface is inwardly gradually increased by the outside of the valve core housing, and the clamping section that there is the outer wall of the spool outer diameter to be gradually increased, the clamping section adapter is set at the card interface.The utility model structure is simple and clear, changes the assembly connection mode of existing valve rod and spool, adds valve core housing, so that scene is conveniently replaceable.
Description
Technical field
The utility model relates to a kind of high pressure single seat spool stem structures.
Background technique
Currently, being generally to pass through screw thread and pin is cooperated to be connected with each other between the intracorporal valve rod of valve and spool.But it is this
Conventional connection type, is unfavorable for live replacement.
Utility model content
The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of high pressure single seat valve core valve stem knot
Structure.
In order to achieve the above object, being achieved through the following technical solutions:
A kind of high pressure single seat spool stem structure, including spool and valve rod, pass through between the spool and the valve rod
Valve core housing is connected with each other.
Preferably, one end of the valve rod has external screw thread, and one end of the valve core housing has internal screw thread, the valve core housing
It is socketed on the valve rod by screw thread.
Preferably, the other end of the valve core housing has card interface, and the outer wall of the spool is arranged at the card interface.
Preferably, the internal diameter of the trapezoidal shape of the card interface and then the card interface by the valve core housing outside inwardly by
Clamping section cumulative big, that there is the outer wall of the spool outer diameter to be gradually increased, the clamping section adapter are set to the card interface
Place.
Preferably, one end of the valve rod is equipped with axial link slot, and one end of the spool is equipped with axial linkage section, described
Axial linkage section adaptation is arranged in the axial link slot.
Preferably, the inside of the valve core housing is equipped with sealed groove, and the sealed groove is located at the interior spiral shell of the valve core housing
Between line section and the card interface, sealing ring is filled in the sealed groove.
The beneficial effect of the utility model high pressure single seat spool stem structure includes:
1) it is mutually socketed between spool and valve rod by valve core housing, avoids spool from being directly spirally connected with valve rod, so as on site
Replacement；
2) spool is connected on valve core housing, is conveniently replaceable very much spool；
3) spool is equipped with axial linkage section, and the valve rod is equipped with axial link slot, is connected to by axial linkage section
Axial link slot, and then play the role of radially limiting to spool and valve rod；
4) leakproofness after spool is connect with valve rod can be effectively ensured in the seal groove in valve core housing and sealing ring.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of high pressure single seat spool stem structure, including spool 1 and valve rod 2, the spool 1 with it is described
It is connected with each other between valve rod 2 by valve core housing 3.
Specifically, in conjunction with shown in Fig. 2 and Fig. 4, one end of the valve rod 2 has external screw thread 20, one end of the valve core housing 3
With internal screw thread 30, the valve core housing 3 is socketed on the valve rod 2 by screw thread.
As shown in figure 4, the other end of the valve core housing 3 has card interface 32, the outer wall of the spool 1 is arranged in the card
At interface 32.
As shown in Figure 3 and Figure 4, the internal diameter of the trapezoidal shape of the card interface 32 and then the card interface 32 is by the valve core housing
3 outside is inwardly gradually increased, the clamping section 10 that there is the outer wall of the spool 1 outer diameter to be gradually increased, and the clamping section 10 is suitable
With being arranged at the card interface 32.
In conjunction with shown in Fig. 2 and Fig. 3, one end of the valve rod 2 is equipped with axial link slot 22, and one end of the spool 1 is equipped with
Axial linkage section 12, axial direction linkage section 12 adaptation are arranged in the axial link slot 22.
In conjunction with shown in Fig. 1 and Fig. 4, the inside of the valve core housing 3 is equipped with sealed groove 34, and the sealed groove 34 is located at institute
It states between the internal thread segment 30 of valve core housing 3 and the card interface 32, is filled with sealing ring in the sealed groove 34.
High pressure single seat spool stem structure provided by the utility model, structure is simple and clear, changes existing valve rod and valve
The assembly connection mode of core, so that scene is conveniently replaceable.
The embodiments of the present invention are only used for being illustrated the utility model, do not constitute to scope of the claims
Limitation, other substantially equivalent substitutions that those skilled in that art are contemplated that, in the protection model of the utility model
In enclosing.
