Description
Technical field
The utility model belongs to valve technology field, specifically a kind of cone seal valve.
Background technique
Valve currently used for connection is there are many kind, including manual rising stem flat valve, manual dark rod flat plate valve
Deng, its shortcoming is that: during open and close, valve rod moves up and down valve, and the sealing element on valve rod is prone to wear, gas or liquid
To know from experience and leaked from valve rod, causes valve short using the time, the maintenance interval is fast, and it is time-consuming and laborious, it is dangerous.
Summary of the invention
What is provided the purpose of the utility model is to overcome disadvantages mentioned above is a kind of long using the time, it is not easy to leak, tie up
Repair few, safe and reliable cone seal valve.
It the utility model aim and solves its technical problem underlying and adopts the following technical solutions to realize:
A kind of cone seal valve of the utility model, including valve seat, valve body, valve rod, spool, in which: installation in the middle part of valve rod
There is spool, spool is mounted below push plate, and push plate is mounted below spring, and spring is mounted below the pin across valve rod, pin
Son is mounted below nut A, and spool blocks the valve core case being arranged on valve body.
Middle face is provided with groove in the push plate, raises upward on side, can move up and down outside valve rod.
Described into being cone above spool, lower middle part is downwardly convex, fluted on side, can be upper and lower outside valve rod
It is mobile.
The downwardly convex part of groove and spool lower middle part that Middle face is arranged in the push plate cooperates, on push plate side upwards
Raised part cooperates with the groove on side below spool.
There is integrated valve body above the valve seat, has integrated valve core case in valve body, ring flange, valve are installed above valve body
Valve rod is installed, valve rod upper and lower end is separately installed with handwheel, flashboard, and flashboard is tightened with nut B, the spiral shell in valve core case in core print seat
Line and valve rod external screw thread cooperate.
The valve rod can move up and down.
The utility model compared with the existing technology, has clear advantage and beneficial effect, from the above technical scheme,
Spool is installed in the middle part of valve rod, spool is mounted below push plate, and push plate is mounted below spring, and spring is mounted below across valve
The pin of bar, pin are mounted below nut A, and spool blocks the valve core case being arranged on valve body, when valve rod pushes flashboard by valve
When closing, spring pushes push plate, and push plate pushes spool to block valve core case, prevents from leaking, when valve rod pulls flashboard to beat valve
When opening, spring thrust increases, and spring pushes push plate, and push plate pushes spool to block valve core case, and sealing is tighter, in a word: this is practical
It is novel long using the time, it is not easy to leak, maintenance is few, securely and reliably.

Specific embodiment
Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes cone seal valve specific embodiment party
Formula, feature and its effect, detailed description is as follows.
Referring to Fig. 1 to Fig. 2, a kind of cone seal valve of the utility model, including valve seat 1, valve body 2, valve rod 4, spool 10,
It is characterized by: being equipped with spool 10 in the middle part of valve rod 4, spool 10 is mounted below push plate 9, and push plate 9 is mounted below spring 5,
Spring 5 is mounted below the pin 3 across valve rod 4, and pin 3 is mounted below nut A11, and spool 10, which is blocked on valve body 2, to be arranged
Valve core case 6.
Middle face is provided with groove in the push plate 9, raises upward on side, can move up and down outside valve rod 4.
Described into being cone above spool 10, lower middle part is downwardly convex, fluted on side, can it is upper outside valve rod 4,
Lower movement.
The downwardly convex part of groove and 10 lower middle part of spool that Middle face is arranged in the push plate 9 cooperates, on 9 side of push plate
The part that raises upward cooperates with the groove on spool 10 below side.
The valve seat 1 has integrated valve body 2 above, there is integrated valve core case 6 in valve body 2, and valve body 2 is equipped with flange above
Disk 7 is equipped with valve rod 4 in valve core case 6, and 4 upper and lower end of valve rod is separately installed with handwheel 8, flashboard, and flashboard is tightened with nut B12,
Screw thread and 4 external screw thread of valve rod in valve core case 6 cooperate.
The valve rod 4 can move up and down.
In use, rotating handwheel 8, the screw thread on valve rod 4 and being threadedly engaged in valve body 2, the rotation of valve rod 4 are run down,
When valve rod 4 pushes flashboard to close valve, spring 5 pushes push plate 9, and push plate 9 pushes spool 10 to block valve core case 6, and sealing is not
Yan Shi, regulating nut A11 run up pin 3, and 5 thrust of spring increases, and can prevent from leaking, and opening is worked as, and rotate handwheel 8,
Screw thread on valve rod 4 and being threadedly engaged in valve body 2, the rotation of valve rod 4 are run up, and valve rod 4 pulls flashboard to open valve, together
When 5 thrust of spring increase, spring 5 push push plate 9, push plate 9 push spool 10 valve core case 6 is blocked.
The preferred embodiment that above are only the utility model, is not construed as limiting the utility model, if it is any without departing from
The content of the technical scheme of the utility model, it is any to make simple modification, equivalent change and modification, still fall within the utility model technology
In the range of scheme.
