Description
Technical field
The utility model relates to a kind of vacuum flapper valve, more particularly to it is a kind of can multi-angle installation vacuum valve.
Background technique
Valve be in the fluid system, for control the direction of fluid, pressure, flow device, be to make piping and equipment
Interior medium (liquid, gas, powder) flows or stops and can control the device of its flow；Wherein, vacuum valve refers to true
In empty set system, for changing airflow direction, throughput size is adjusted, the vacuum system element of pipeline, vacuum valve are switched off or on
Door closure member is sealed with as glue sealing ring or metal o-ring.
In actual application, large-scale flapper valve mostly uses vertically-mounted mode to be installed, but according to actual
It needs, needs to tilt flapper valve and install, if the large-scale flapper valve that diameter is 1.8m is when tilting installation, due to valve inner
Valve plate is heavier, and valve plate can reach 1 ton or so, and the stroke of valve plate is 1.3m, in actual production, simultaneously because valve body is interior
Portion is not easy to be processed, so that having gap between valve plate and valve body, for valve rod when pushing valve plate mobile, the weight of valve plate itself is larger
And there is gap between valve plate and valve body, valve plate is easy to happen shaking when moving, so that valve rod easily occurs bending and deformation, makes
After obtaining valve rod movement, the sealing ring installed on the valve seat that valve plate cannot be connected with valve body be contacted, or because valve rod deformation is curved
Song leads to valve plate shallow decline, prevent the sealing ring on valve plate leaks air from being in close contact with the sealing ring on valve seat
Situation；General solution is that the direct diameter for increasing valve rod avoids valve rod bending deformation so that the rigidity of valve rod is stronger；
But also will increase the quality of valve rod in this way, increase the manufacturing cost of valve rod, while bigger power being needed to come driving stem and valve
Plate.
Utility model content
The purpose of this utility model is to provide it is a kind of can multi-angle installation vacuum valve, which can use a variety of
Different angle installations, at runtime, valve plate will not shake the valve after installing, while valve rod will not bend
The case where deforming, avoiding the occurrence of gas leakage.
In order to solve the above technical problems, the technical scheme adopted by the utility model is:
It is a kind of can multi-angle installation vacuum valve, including valve body, valve rod and valve plate, valve plate is set to the inside of valve body, valve
The inside that the cooperation of bar and valve seal extendes back inlet valve body is connected with valve plate, valve rod for pushing valve plate mobile, after valve plate declines and
The sealing ring contact installed on the valve seat of valve body connection, it is characterised in that: it further include support guide mechanism, the support guide machine
Structure includes guide rod and linear bearing, and guide rod is fixedly mounted in valve body, and linear bearing is mounted on valve plate, linear bearing and guide rod
It cooperates.
The valve plate lower end is equipped with the first sealing ring.
The support guide mechanism further includes linear guide and sliding block, and linear guide is vertically installed in valve body, sliding block peace
On valve plate, sliding block and linear guide cooperate.
The support guide mechanism further includes guide post and idler wheel, and the guide post is mounted on the inside of valve body, and guide post is equipped with
Groove, idler wheel are mounted on valve plate by shaft, and the surface of idler wheel is contacted with groove floor, and when valve plate moves, idler wheel is in groove
Interior rolling.
It is arranged with sleeve outside the valve rod, sleeve upper end is fixedly connected with the valve body, and lower end is hanging.
The sleeve both ends are equipped with boss, are equipped with multiple support columns between boss.
Multiple reinforcing ribs are equipped with along its axis direction on the valve rod.
Compared with prior art, the utility model has the following beneficial effects:
1. the utility model valve rod pushes valve plate movement to realize valve opening and closing purpose, the support guide mechanism includes guide rod
And linear bearing, guide rod are fixedly mounted in valve body, linear bearing is mounted on valve plate, and linear bearing and guide rod cooperate；
During valve rod pushes valve plate mobile, guide rod is oriented to valve plate, so that valve plate is moved along guide rod, i.e. the axle center of valve plate
The axial line of line and valve rod is always maintained on one wire, and linear bearing and guide rod mutual cooperation gap are smaller, and valve plate is in movement
When be not susceptible to shake, meanwhile, guide rod provides a holding power for valve plate, in this way valve rod push valve plate during, valve rod
The case where being not in bending deformation, valve plate will not run-off the straight, this ensure that valve plate can be in close contact with sealing ring,
It ensure that leakproofness when valve is closed；Meanwhile when valve is tilted installation, since valve plate is supported by guide rod, valve plate is not
Valve rod can be bent, so that valve during installation, can be installed using a variety of setting angles, improve the suitable of valve
Ying Xing.
2. valve plate lower end described in the utility model is equipped with the first sealing ring, the leakproofness of valve is further improved.
3. support guide mechanism described in the utility model further includes linear guide and sliding block, linear guide is vertically installed at valve
In vivo, sliding block is mounted on valve plate, and sliding block and linear guide cooperate, so that valve plate is more flat when mobile
Surely, meanwhile, the fit clearance of sliding block and line slide rail is smaller, and when valve rod pushes valve plate mobile, valve plate is not susceptible to shake,
It is more steady in valve plate operational process, it further avoids that valve plate is overweight to cause valve rod to be bent so that valve plate tilts, further protects
The close contact of valve plate and sealing ring is demonstrate,proved, to improve the leakproofness of valve.
4. support guide mechanism described in the utility model further includes guide post and idler wheel, the guide post is mounted on the interior of valve body
Portion, guide post are equipped with groove, and idler wheel is mounted on valve plate by shaft, and the surface of idler wheel is contacted with groove floor, valve plate movement
When, idler wheel rolls in groove, and valve after installing at different angles, and groove can provide valve plate when moving for idler wheel
Support force avoids valve plate from bending valve rod, to guarantee the sealing performance of valve.
5. being arranged with sleeve outside valve rod described in the utility model, sleeve upper end is fixedly connected with the valve body, and lower end is hanging；In this way
The inner sidewall of sleeve provides a restraining force for valve rod, which is support force, avoids causing valve rod to be bent because valve plate is overweight,
To avoid valve plate from tilting, cause valve plate that cannot be in close contact with sealing ring.
6. sleeve both ends described in the utility model are equipped with boss, multiple support columns, the setting of support column are equipped between boss
The stability of sleeve is further improved, for valve rod in bending, valve rod presses to the inner wall of sleeve, the branch of such sleeve stress side
Dagger plays the role of support, and the support column that sleeve is not affected by the side of power holds sleeve, and avoiding sleeve, deformation occurs.
7. being equipped with multiple reinforcing ribs along its axis direction on valve rod described in the utility model, the setting of reinforcing rib is so that valve
The structure of bar is more stable.
