Abstract
The utility model is high temperature and high pressure cut-off valve valve rod anti-rotation device, including the support being arranged on the outside of valve rod, the pedestal upper end is transversely provided with through hole, and plunger is provided with the through hole, the slot coordinated with steady pin is provided with the plunger, the steady pin is arranged on clip spring seat.The utility model high temperature and high pressure cut-off valve valve rod anti-rotation device, provided with plunger, coordinated by steady pin in plunger on clip spring seat, form activity stem structure, valve rod can be adjusted adaptively, it is ensured that accurate concentricity, while avoid HTHP lower valve rod from being fractureed by larger power.
Description
Technical field
Valve technology field is the utility model is related to, especially a kind of regulating valve rod side village device.
Background technology
Valve be in fluid system, for control the direction of fluid, pressure, flow device, be to make pipe arrangement and equipment
Interior medium（Liquid, gas, powder）Flowing stops and can control the device of its flow.The control of valve can use a variety of biographies
Flowing mode, such as manually, electrically, surge, pneumatically, turbine, electromagnetic driven, electromagnetism surge, electro-hydraulic dynamic, air-or liquid-operated, spur gear, bevel gear
Driving etc..
But common valve, when being worked in the environment of HTHP, the pressure that valve rod is subject to is very big, common hexagonal
Groove anti-rotation designs, and valve rod is deflected under high pressure-temperature, in the case of biasing force, stress valve rod easily fractures, shadow
Ring valve service life.
Utility model content
The technical problems to be solved in the utility model is to provide high temperature and high pressure cut-off valve valve rod anti-rotation device, solves existing
Technology easily occur valve rod rotate, the situation of skew, the problem of influenceing valve service life.
The utility model is achieved through the following technical solutions：
High temperature and high pressure cut-off valve valve rod anti-rotation device, including the support on the outside of valve rod is arranged on, the pedestal upper end is horizontal
Provided with through hole, plunger is provided with the through hole, is provided with the slot coordinated with steady pin in the plunger, the steady pin is arranged on
On clip spring seat.
The further improvement project of the utility model is that the front end of the plunger is conformed with.
The further improvement project of the utility model is that the steady pin is flat.
The further improvement project of the utility model is that the through hole is located at support side upper end, positioned at the upper of observation panel
End.
The utility model compared with prior art, has the following advantages that：
1st, the utility model high temperature and high pressure cut-off valve valve rod anti-rotation device, provided with plunger, coordinated by steady pin in plunger
On clip spring seat, activity stem structure is formed, valve rod can be adjusted adaptively, it is ensured that accurate concentricity, while avoid high temperature height
Pressure valve rod is fractureed by larger power；
2nd, the clip spring seat is set so that it is more uniformly stressed, it is more firm；
3rd, the steady pin is flat, bigger with the contact surface of valve rod, increases steadiness.
The utility model is described further with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is the support schematic diagram of the utility model high temperature and high pressure cut-off valve valve rod anti-rotation device.
Fig. 2 is the plunger schematic diagram of the utility model high temperature and high pressure cut-off valve valve rod anti-rotation device.
Wherein：1- supports, 2- through holes, 3- plungers, 4- slots, 5- clip spring seats, 6- projections, 7- observation panels.
Embodiment
High temperature and high pressure cut-off valve valve rod anti-rotation device shown in Fig. 1 and Fig. 2, including the support 1 on the outside of valve rod is arranged on, it is described
The upper end of support 1 is transversely provided with through hole 2, and plunger 3 is provided with the through hole 2, the slot coordinated with steady pin is provided with the plunger 3
4, the steady pin is arranged on clip spring seat 5；The front end of the plunger 3 is conformed with 6；The steady pin is flat；Institute
State through hole 2 and be located at the side upper end of support 1, positioned at the upper end of observation panel 7.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
