Description
Technical field
The utility model relates to Special valve field, the valve stem seal mechanism of especially a kind of poppet.
Background technique
CN201020010116.0 discloses a kind of Linear sealing valve, including main valve body, auxiliary valve body, valve seat, flap, valve rod
And bracket, auxiliary valve body both ends have feed inlet and outlet, be connected to it is inclined for main valve body in the middle part of auxiliary valve body, be supported on main valve body it is oblique on
There is bracket in side and valve rod is arranged in valve chamber, and valve seat is fixed by main valve body and auxiliary valve body, and flap is mounted on valve rod bottom end with it
It moves up and down, it is characterized in that: sealing structure is cooperatively formed by valve seat and flap, sealing surface of seat forms radian, the sealing of flap
Face forms inclined-plane, and cooperation is contacted in loop wire to realize sealing between valve seat and flap.No matter the program is in shape of closing or circulate
State, the valve can remain good leakproofness.
The valve rod of above scheme is not provided with valve stem sleeve.
In this Special valve, it is necessary to which valve stem sleeve is set, because valve rod is spliced by three sections of small valve-rods.And if
Valve stem sleeve is set, unless welding or valve stem sleeve and valve rod are bolted between valve stem sleeve and valve rod, if using weldering
The mode connect, then it is more troublesome.If be bolted, at least intermediate valve rod should be it is solid, if it is solid,
Weight is larger.And if it is hollow, the then easy gas leakage of bolt.
So no matter using that above-mentioned mode, it is perfect in every way to be unable to reach.
Utility model content
The purpose of the utility model is to provide a kind of valve stem seal mechanism of poppet, which can connect any
The upper valve rod and lower valve rod of form, can be realized and preferably seal at valve face.
Technical solution provided by the utility model are as follows: a kind of valve stem seal mechanism of poppet, including middle valve rod；Described
The middle part fixed seal connection of middle valve rod has valve face；The middle valve rod is hollow middle valve rod, the middle part of the middle valve rod
Equipped with the partition for both sides sealing above and below middle valve rod to be isolated, the upper and lower part of the middle valve rod is equipped with level and runs through
The bolt hole of the side wall of middle valve rod.
In the valve stem seal mechanism of above-mentioned poppet, the symmetrical cloth of bolt hole of the upper and lower part of the middle valve rod
It sets；The bolt hole on the top of the middle valve rod includes 2 the first bolts hole from top to bottom arranged and 1 the second bolt hole,
Wherein, the first bolt hole and the second bolt hole are mutually perpendicular to.
In the valve stem seal mechanism of above-mentioned poppet, the first bolt hole and the second bolt hole interlaced arrangement.
In the valve stem seal mechanism of above-mentioned poppet, the valve face is equipped with the rivet hole that a circle is evenly arranged.
The utility model is after adopting the above technical scheme, it has the beneficial effect that
This programme develop it is a kind of for connecting a kind of valve stem seal mechanism of upper valve rod and lower valve rod, it is small in size, easily
In processing, there is partition in centre, it is ensured that will not lead to gas leakage because of the connection with upper valve rod and lower valve rod.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the utility model embodiment 1；
Fig. 2 is the main view of the utility model embodiment 1；
Fig. 3 is the cross-sectional view of the utility model embodiment 1.
Specific embodiment
With reference to embodiment, the technical solution of the utility model is described in further detail, but not structure
Any restrictions of pairs of the utility model.
Embodiment 1:
Such as Fig. 1-3, a kind of valve stem seal mechanism of poppet, including middle valve rod 1；The middle part of the middle valve rod 1 is fixed
It is sealedly connected with valve face 2；The middle valve rod 1 is hollow middle valve rod 1, the middle part of the middle valve rod 1 be equipped with for will in
The partition 3 of about 1 both sides sealing of valve rod isolation, the upper and lower part of the middle valve rod 1 are equipped with level through middle valve rod 1
The bolt hole of side wall.
In practical applications, the lower valve rod of the upper valve rod and peripheral hardware of middle valve rod 1 and peripheral hardware by bolt hole and bolt into
Row connection is arranged partition 3 at the middle part of middle valve rod 1, can effectively avoid the middle valve rod 1 of 2 position of valve face in order to avoid gas leakage
Generation caused by inside the phenomenon that gas leakage.
In the present embodiment, the bolt hole of the upper and lower part of the middle valve rod 1 is arranged symmetrically；The middle valve rod 1
The bolt hole on top include 2 first the second bolts hole of bolt hole 4 and 15 from top to bottom arranged, wherein the first bolt
Hole 4 and the second bolt hole 5 are mutually perpendicular to, 5 interlaced arrangement of the first bolt hole 4 and the second bolt hole, and the valve face 2 is equipped with one
The rivet hole 6 being evenly arranged is enclosed, rivet hole 6 is for being allowed to be formed a bigger valve face with what other valve faces were attached.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned
The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing
In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
