Description
Technical field
The utility model relates to angle pedestal valve, in particular to a kind of angle pedestal valve with movable valve seat.
Background technique
It is that valve rod band movable valve plug acts under valve working state, realizes the effect of pipeline high-speed switch, service life is direct
It is decided by the design of valve rod and spool.It is as shown in Figure 2 to say that multiple components form a whole component, then and valve in the prior art
Body 16 is grouped together, and is exactly a complete angle valve.This cooperation influences the concentricity of valve, leakage degree and maintenance difficulties.
Locking nut 11 and valve body 16 are only by being threadedly engaged, without positioning surface, it is difficult to guarantee whole operation component and valve body sealing surface
Concentricity.Part 12 is sealing element, it is ensured that leakage degree.When operating member one and 16 valve bodies assemble, need in air pressure mouth
3 positions connect compressed gas source, and then whole part rotates, and screw thread can just be tightened, and operation difficulty is big.If there is failsafe valve,
Need to overhaul, also integrally screw out after logical upper gas source, execute-in-place difficulty is bigger.
Summary of the invention
The main purpose of the utility model is to provide a kind of angle pedestal valves with movable valve seat, can effectively solve background
The problems in technology.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of angle pedestal valve with movable valve seat, including valve body and cylinder are equipped with connection component, gas between valve body and cylinder
Piston and valve rod are equipped in cylinder, valve rod passes through connection component and is connected with the intracorporal spool of valve is set to, the inner surface of cylinder upper cover
Reset spring is equipped between piston, cylinder side is equipped with the air pressure mouth for increasing or decreasing air pressure；Connection component includes the
One connecting column and the second connecting column being sheathed on the first connecting column, valve rod are located inside the first connecting column, the first connecting column
One end is threadedly coupled with cylinder, and other end outer surface is equipped with the annular convex platform for limiting to the second connecting column, the second connecting column
It is connect with valve body screw thread.
Preferably, being equipped with fluid inlet in valve body with fluid outlet and whether two mouthfuls are connected to by spool to control.
Preferably, being equipped with tapered opening between fluid outlet and fluid inlet, the section of spool is cross-shaped structure, bottom
Portion is conical head and conical head is deep into tapered opening and cooperates with tapered opening；Outer edge in the middle part of spool is equipped with a circle notch
And indentation, there is equipped with sealing ring；It is connect at the top of spool with the bottom end of valve rod.
Compared with prior art, the utility model has the following beneficial effects: the valve rod in the utility model has benchmark
Face and valve body cooperation, the second connecting column can be move freely, and be responsible for locking；Installation and removal are all the lists behind air pressure mouth ventilation source
Solely the second connecting column of rotation, substantially increases the efficiency of installation and removal.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
Fig. 2 is the cross-sectional view of the prior art.
