Abstract
The utility model discloses a lead screw anticreep valve, which comprises the following components: a valve body, install the valve gap on the valve body, the valve gap embeds the bearing frame, the bearing frame is two, and the diaxon bearing is all near valve gap both sides setting, the valve gap mid -mounting has the bearing nut to connect, the bearing nut connects mechanical connection on the valve gap, the bearing nut joint is close to top department and is equipped with screw nut, screw nut passes through limiting plate and bearing nut articulate, the limiting plate passes screw nut respectively and the bearing nut connects the setting, the bearing nut connects the top and is equipped with the flashboard, flashboard swing joint is on the bearing nut connects, this lead screw anticreep valve has simple structure, no seepage, the anticreep effect of playing that can be better, and operate steadily, and the load bearing capability is large, it is little to pass kinetic friction coefficient simultaneously, lead to the switch moment of valve less, thereby operating time has been shortened greatly, and a work efficiency is increased.
Description
Technical field
The utility model relates to a kind of anticreep valve, particularly a kind of leading screw anticreep valve.
Background technique
Current gate valve is generally hand wheel rotating reaches folding object with screw thread nut rotating threaded shaft handling valve plate, but owing to only having 1/3rd screw threads in screw thread nut copper sheathing top, thus cause and easily wear and tear again when promoting leading screw herein and break de-, particularly industrial mesohigh valve, when leading screw ruptures, the accident that leading screw is got by high pressure water can be there is, bring injury to operator, substantially increase security risk coefficient.
Model utility content
The technical problems to be solved in the utility model is: overcome the problems referred to above, and provide one to have structure simple, ne-leakage, can better play anticreep effect, and operate steadily, the leading screw anticreep valve that bearing capacity is large.
To achieve these goals, the technical solution adopted in the utility model is such: leading screw anticreep valve of the present utility model, comprise valve body, valve body is provided with valve gap, valve gap built-in bearing seat, bearing support is two, and diaxon bearing is all arranged near valve gap both sides, bearing nut joint is installed in the middle part of valve gap, bearing nut joint mechanical is connected on valve gap, bearing nut joint is provided with feed screw nut near top place, feed screw nut is connected with bearing nut joint by limiting board, limiting board is each passed through feed screw nut and bearing nut joint is arranged, bearing nut joint top is provided with flashboard, flashboard is movably connected on bearing nut joint.
Further, as a kind of concrete structural type, between valve body described in the utility model and valve gap, crossover sub is connected with.
Further, as a kind of concrete structural type, feed screw nut described in the utility model detains feed screw nut entirely for lengthening.
Further, as a kind of concrete structural type, between bearing support described in the utility model and bearing nut joint, seal arrangement is connected with.
Further, as a kind of concrete structural type, limiting board described in the utility model is steel structure limiting board.
Further, as a kind of concrete structural type, valve gap described in the utility model has the slotted eye connected for bearing support.
Compared with prior art, the utility model has the advantage of: it is simple that this leading screw anticreep valve has structure, ne-leakage, can better play anticreep effect, and operate steadily, bearing capacity is large, gearing friction coefficient is little simultaneously, cause the switch moment of valve less, thus substantially reduce the operating time, improve working efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model; In figure: 1. valve body; 2. valve gap; 3. bearing support; 4. bearing nut joint; 5. feed screw nut; 6. limiting board; 7. flashboard.
Embodiment
Be described in further detail the utility model by reference to the accompanying drawings now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The preferred embodiment of the utility model leading screw anticreep valve as shown in Figure 1, comprise valve body 1, valve body 1 is provided with valve gap 2, valve gap 2 built-in bearing seat 3, bearing support 3 is two, and diaxon bearing 3 is all arranged near valve gap 2 both sides, bearing nut joint 4 is installed in the middle part of valve gap 2, bearing nut joint 4 is mechanically connected on valve gap 2, bearing nut joint 4 is provided with feed screw nut 5 near top place, feed screw nut 5 is connected with bearing nut joint 4 by limiting board 6, limiting board 6 is each passed through feed screw nut 5 and bearing nut joint 4 is arranged, bearing nut joint 4 top is provided with flashboard 7, flashboard 7 is movably connected on bearing nut joint 4, crossover sub is connected with between described valve body 1 and valve gap 2, described feed screw nut 5 detains feed screw nut entirely for lengthening, seal arrangement is connected with between described bearing support 3 and bearing nut joint 4, described limiting board 6 is steel structure limiting board, described valve gap 2 has the slotted eye connected for bearing support 3.
It is simple that leading screw anticreep valve of the present utility model has structure, ne-leakage, can better play anticreep effect, and operate steadily, bearing capacity is large, gearing friction coefficient is little simultaneously, cause the switch moment of valve less, thus substantially reduce the operating time, improve working efficiency, be connected with crossover sub between described valve body 1 and valve gap 2, conversion can be carried out according to actual conditions and connect; Described feed screw nut 5 detains feed screw nut entirely for lengthening, and lengthens the design of full button feed screw nut, greatly strengthen overall using effect; Be connected with seal arrangement between described bearing support 3 and bearing nut joint 4, there is good sealing; Described limiting board 6 is steel structure limiting board, and using effect is better; Described valve gap 2 has the slotted eye connected for bearing support 3, the tightness be convenient between bearing support 3 with valve gap 2 is connected.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff completely can in the scope not departing from this model utility technological thought, carry out various change and amendment, the technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
