The utility model aims at providing a processing convenient assembling, the reliable and stable ball valve knob revolution mechanic of use.
Description
Technical field
This utility model belongs to ball valve field, particularly relates to a kind of ball valve knob rotational structure。
Background technology
At present, ball valve knob rotating part structure on the market generally has two kinds of structures, and knob pin is fixed or knob core is fixed。For the first structure, the steady pin on knob valve body is fixing prevents knob from deviating from, and turning knob realizes opening and closure state, and rotational angle is positioned by steady pin。But such structure, steady pin needs alignment knob gap position from valve body side when loading, assemble comparatively inconvenience trouble, and one end of steady pin be exposed。When using tiny steady pin fixing, knob is subject to power up or down easily makes knob get loose, and during steady pin orientation angle, and the knob excessive location that also easily causes of exerting oneself is inaccurate or lost efficacy。
For the second structure, such as China Patent Publication No.: CN202834156U, disclose a kind of Non-follow control ball valve, including valve body, valve, valve rod, valve is arranged in described body cavity, and valve rod is connected with valve, valve body includes one and enters water cavity and a water chamber, valve rod stretches out the one end of valve and is connected to handle and fixes with clamp nut, and one end that valve rod is connected with valve is provided with dovetail groove, and valve is provided with the groove matched with dovetail groove。But such structure, relatively position difficulty processed by dovetail groove in core, relatively costly, needing knob and core same fashionable dress when assembling knob, first knob is loaded into, turning knob assembles core again notch alignment core swallowtail trough structure, two parts need cooperation, assemble more difficult；Because not having the first structure high with its firmness of swallowtail trough structure fixed knob, also higher requirement is proposed the mechanical performance of knob component。
Utility model content
This utility model is to overcome above-mentioned deficiency of the prior art, it is provided that a kind of process and assemble is convenient, use reliable and stable ball valve knob rotational structure。
To achieve these goals, this utility model is by the following technical solutions:
A kind of ball valve knob rotational structure, including valve body and be arranged on the core in valve body, also include the knob being connected with core, the knob base for positioning knob it is provided with in the middle part of described valve body, the through hole connected with core it is provided with in described knob base, being provided with fixing knob locating ring in described through hole, described knob and knob locating ring connect and fix。So, knob is positioned by the knob base of knob locating ring Yu valve body, and knob rotates thus realizing the stable opening and closing of ball valve with the core in moving valve。Knob and knob locating ring are by connecting and fixing, it is prevented that knob and valve body depart from, and assemble more convenient, improve production efficiency。
As preferably, described knob is provided with the positive stop of arc, and described positive stop is with knob rotating shaft for the center of circle, and described knob base is provided with the stopper slot limiting positive stop rotational angle。Being coordinated by positive stop and stopper slot, limit the rotational angle of knob, stopper slot is for the accurate positioning of knob, and bulk strength is bigger, it is possible to is prevented effectively from location and is forbidden and lost efficacy。
As preferably, described core is provided with groove, and described knob is provided with the trip with groove fit。So, being coordinated by groove and trip between core with knob, it is achieved the rotation of core, core need not be fixedly connected with knob, reduces difficulty of processing, simplifies installation process。
As preferably, the top of described through hole is provided with shoulder hole, and the inwall of described shoulder hole is provided with locating ring draw-in groove, and it is protruding that described knob locating ring is provided with the clamping with locating ring draw-in groove interference fit。
As preferably, described knob locating ring inwall is provided with knob draw-in groove, and described knob is provided with flange, the top of described flange and knob draw-in groove matched in clearance。
As preferably, being provided with sealing ring between described valve body and knob, described through-hole wall is at the seal groove being connected with accommodation sealing ring of knob locating ring。
The beneficial effects of the utility model are: knob is positioned by (1) by knob locating ring, improve the firmness of knob and the stability of rotation；(2) process and assemble more convenient, advantageously reduce cost and improve production efficiency。

In figure: valve body 1, knob base 1a, shoulder hole 11, locating ring draw-in groove 12, through hole 101, stopper slot 102, sealing ring 2, knob locating ring 3, knob draw-in groove 3a, clamping projection 3b, knob 4, flange 401, trip 402, positive stop 403, link 4a, handle end 4b, core 5, groove 501。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described。
In embodiment as shown in Figure 1, a kind of ball valve knob rotational structure, including valve body 1, core 5 and knob 4。Wherein, being provided with passage in valve body, core is arranged on the channel middle of valve body, thus dividing the channel into two parts。Core is provided with hole, thus can be connected by two parts of passage。It is provided with the knob base 1a for positioning knob in the middle part of valve body, in knob base, is provided with the through hole 101 connected with core。Knob includes handle end 4b and link 4a, and link is inserted in through hole, and the top of link is provided with trip 402, and core upper end is provided with groove 501, the trip of knob can with groove fit, thus driving core to rotate。Being provided with fixing knob locating ring 3 in through hole, knob and knob locating ring connect and fix。The top of through hole is provided with shoulder hole 11, and the inwall of shoulder hole is provided with locating ring draw-in groove 12, and knob locating ring is provided with and the clamping projection 3b of locating ring draw-in groove interference fit。Knob locating ring inwall is provided with knob draw-in groove 3a, and knob is provided with flange 401, the top of flange and knob draw-in groove matched in clearance。Being provided with sealing ring 2 between valve body and the link of knob, through-hole wall is at the seal groove being connected with accommodation sealing ring of knob locating ring。
As shown in Figure 2 and Figure 3, knob is provided with the positive stop 403 of arc, and positive stop is with knob rotating shaft for the center of circle, and knob base is provided with the stopper slot 102 limiting positive stop rotational angle。The center of circle angle that stopper slot is corresponding is 180 degree, and center of circle angle corresponding to positive stop is 90 degree, so that knob can along stopper slot 90 degree of rotations back and forth so that ball valve opens and closes。
When practical set, first sealing ring and knob locating ring are pressed in the knob base of valve body, the mode utilizing locating ring draw-in groove and knob clamping projection interference fit prevents knob locating ring from getting loose, then knob it is pressed into again, the knob draw-in groove matched in clearance of the flange of knob and knob locating ring, it is ensured that knob is smooth and easy。The simultaneously groove fit of the trip of knob and core。Knob is when rotating, even if when being subject to power bigger up or down, knob is not easy to, and rotational angle location is also comparatively accurate, stable。
