Abstract
The utility model discloses a rotary motion valve; which is characterized in that the frame has a structure like the Chinese character ri, the middle clapboard is rotated in radial and cooperated with the valve rod by a bearing and axially fixedly connected with the valve rod screw thread part by bearing and nuts, and then the bearing mechanism of the valve rod axially position device and the valve inner components is formed. The utility model has the advantages of labor saving in switch the valve, smart operation, no libration of the valve inner components, less wearing between the valve core and the valve body, good sealing performance and long service life.
Description
Technical field
The utility model belongs to valve part, specifically, is a kind of rotary motion valve mounting bracket.
Background technique
The valve that latus rectum is bigger, volume, the weight of its drive unit (operating grip of manually-operated gate, the final controlling element of automatic valve) are also bigger, therefore, with mounting bracket drive unit are supported on the valve body usually.Mounting bracket makes the structural stability of valve, and each in addition, the relative position of parts determines, valve can proper functioning; Simultaneously, the gravity that also makes drive unit through the support transfer function on valve body, and can be on valve seat through trim (valve rod and spool) transfer function.In addition, the valve that latus rectum is big, the weight of trim is also very big, linear motion valves such as gate valve, stop valve, the gravity of trim is born by drive unit, also acts on the valve body at last.But ball valve, butterfly valve isogonism stroke valve, the gravity of trim then is to act on the valve seat, causes valve open and close effort, aggravation spool, the prooving of valve seat.As seen, existing " mouth " font mounting bracket only is applicable to linear motion valves such as gate valve, stop valve, does not also solve the problem of supporting rotary motion valve trim gravity.
In addition,,, do not allow trim to go here and there up and down, but during actual the use, the pressure surge meeting of medium is vibrated trim in the valve, occurs going here and there up and down moving for guaranteeing trim and valve body accurately location and sealability for ball valve, butterfly valve isogonism stroke valve.
The model utility content
The purpose of this utility model provides a kind of rotary motion valve support that can avoid above-mentioned negative consequence, and the gravity of trim is by bracket supports, and valve rod is by the support axially locating, and trim can not gone here and there up and down.Because the valve rod of rotary motion valve need only rotate, and must not move axially, make and realize that above-mentioned purpose becomes possibility, can realize above-mentioned purpose by implementing following technical solution.
A kind of rotary motion valve mounting bracket, it is characterized in that: support is " day " font structure, its middle transverse slat radially is being rotatably assorted by bearing and valve rod, is connected in axially locating with the threaded stem section by bearing, nut, constitutes the support mechanism of valve rod axial direction positioning device and trim gravity.
The center of transverse slat is porose in the described support, upper and lower end face is established the deep gouge concentric with the hole, establish radial thrust bearing in the deep gouge, valve rod is among hole and bearing, the upper and lower thread section in stem bearing position is respectively equipped with nut, nut is pushed down the end face of upper and lower bearing, and on the transverse slat, nut was provided with lock screw or locking nut during valve rod was positioned at.
Establish two power double row self aligning ball bearings in the described support in the center hole of transverse slat, there is internal thread at two ends, center hole bearing position, and the inner ring of bearing is fixed on the valve rod by internal threaded nut, and the outer ring is fixed on the middle transverse slat by two outside thread nuts.
The beneficial effects of the utility model are, the gravity of trim is by bracket supports, and the valve open and close is laborsaving, flexible operation; Valve rod is by the support axially locating, and the trim friction can not gone here and there up and down, and spool and valve body wearing and tearing are few, good seal performance, long service life.
The utility model below is described in detail in detail.
