Description
Technical field
The invention belongs to technical field of valve manufacturing, and in particular to a kind of integral type valve core sealing mechanism.
Background technique
Under normal conditions, the flap of small-bore shut-off valve and valve rod are made of one formula structure applied to high-pressure stop valve and section
Flow the types such as valve, needle valve, high voltage generating station valve, sampling valve, gauge valve.However, for mesolow, low temperature, high temperature, with small
Small-bore shut-off valve in the operating conditions such as granular media, is nearly all connect for flap and valve rod using T-slot or other connection types,
Process is tedious in processing and manufacturing, more demanding to operator, valve rod easily occurs and flap centering is failed；In actual use
Spool is easy to appear stuck, guiding is crooked and switch is not in place and other issues, reduces the reliability of product, or even give user
It causes damages.Therefore, optimize valve body and the sealing mechanism of flap type of attachment is still imperative.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of integral type valve core sealing mechanism
Problem.
To achieve the above object, the invention provides the following technical scheme: a kind of integral type valve core sealing mechanism, including valve
Body, the valve body are internally provided with spool, guide rod are provided with above spool, is provided on valve body corresponding with spool
Sealing surface on valve deck, the bottom end of spool are provided with valve core sealed cover, and valve body corresponding with valve core sealed cover is provided on valve body
Sealing surface, the valve body sealing surface are conical seal (contact) face, and valve body sealing surface and valve core sealed cover form line contact sealing.
As a further solution of the present invention: the valve core sealed cover is spherical surface.
As further scheme of the invention: the guide rod is plunger type guide rod.
As the present invention further scheme: the upper surface of the guide rod is provided with secondary sealing area, and described second
Sealing surface is conical seal (contact) face.
Compared with prior art, the beneficial effects of the present invention are: the present invention realizes trim using structure improved spool
Modularization reduces part manufacturing procedure, reduces valve body middle chamber height, production cost is effectively reduced；Valve seal pair build-up wear-resistant
Alloy material guarantees that spool antifraying property is good；Secondly, guide rod is provided on integral type valve core sealing mechanism, to make
Valve medium in horizontally or vertically installation and operation is not easy to leak.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the partial enlarged view under the corresponding open state of the present invention；
In figure: 1- valve body, 2- spool, 3- valve body sealing surface, 4- valve core sealed cover, 5- guide rod, sealing surface on 6- valve deck.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 and Fig. 2 are please referred to, the present invention provides a kind of technical solution: a kind of integral type valve core sealing mechanism, including valve body
1, valve body 1 is internally provided with spool 2, and spool 2 is the integral structure that valve rod is synthesized with flap, and the top of spool 2 is provided with
Guide rod 5 is provided with sealing surface 6 on valve deck corresponding with spool 2 on valve body 1, and the bottom end of spool 2 is provided with valve core sealed cover
4, valve body sealing surface 3 corresponding with valve core sealed cover 4 is provided on valve body 1；
Fig. 1 and Fig. 2 are please referred to, in order to keep the sealing effect between valve core sealed cover 4 and valve body sealing surface 3 more preferable, this reality
It applies in example, it is preferred that valve core sealed cover 4 is spherical surface, valve seal pair build-up wear-resistant alloy material, to make the anti-wiping of spool 2
It is good to hurt performance；
Fig. 1 and Fig. 2 are please referred to, in order to keep the guide effect of guide rod 5 more preferable, in the present embodiment, it is preferred that guide rod 5
For plunger type guide rod, no matter valve is horizontally mounted or right angle setting, and guide rod 5 can avoid valve to be occurred in the process of running
Problem stuck, guiding is crooked and switch is not in place, and then medium leakage is prevented, guide rod 5 is protected with valve rod and valve seat orifice
Concentricity is demonstrate,proved, and is provided with lumen corresponding with guide rod 5 on valve body 1, the interior table of the outer surface of guide rod 5 and the lumen
Gap is provided between face；
Fig. 1 and Fig. 2 are please referred to, in order to keep the sealing effect of valve body sealing surface 3 more preferable, in the present embodiment, it is preferred that valve body
Sealing surface 3 is conical seal (contact) face, and valve body sealing surface 3 and valve core sealed cover 4 form line contact sealing, in order to make guide rod 5
The sealing effect of used time is more preferable, in the present embodiment, it is preferred that the upper surface of guide rod 5 is provided with secondary sealing area, the second sealing
Face is conical seal (contact) face, and secondary sealing area fits like a glove after valve opening with sealing surface 6 on valve deck, to form first of valve
Bar sealing, effectively avoids valve from medium leakage occur.
The working principle of the invention and process for using: when in use, the small-bore shut-off valve of mesolow is that low in and high out is situated between
Mass flow is to when valve is in close state, the spherical seal surface on spool 2 forms line with the conical seal (contact) face on valve body 1 and contacts
Sealing, seal pressure is big, good seal performance；Valve seal pair build-up wear-resistant alloy material, to make the antifraying property of spool 2
More preferably, valve service life is effectively ensured.
