Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, the embodiment discloses a valve limit indicating mechanism, including gear box 1, dust cover 2 of setting in gear box 1 top and wear to establish the valve rod 3 in gear box 1, dust cover 2 one side is provided with protruding chamber 4 of intercommunication, and the top and the bottom in protruding chamber 4 all are provided with limit switch annunciator 5, and protruding chamber 4 plays the effect in increase space, easy to assemble limit switch annunciator 5. An indication induction device 6 which can be matched with any limit switch annunciator 5 is arranged on the valve rod 3; wherein, instruct induction system 6 part to stretch into in protruding chamber 4, instruct and leave the interval between induction system 6 and the limit switch annunciator 5 to avoid valve rod 3 lift in-process to instruct induction system 6 and limit switch annunciator 5 to appear colliding and damaging the influence and use.
This valve limit indication mechanism is through installing indication induction system 6 on valve rod 3, install two limit switch signal ware 5 on protruding chamber 4, two limit switch signal ware 5 correspond the open position and the closed position of valve respectively, valve rod 3 can drive under gear box 1's drive and instruct induction system 6 to make elevating movement, be close corresponding limit switch signal ware 5 when instructing induction system 6, can judge the on-off state of valve, and has the advantages of overall structure simply, valve position indication and the clear reliable of sensing.
On the basis, for making things convenient for the later stage to maintain or change instruction induction system 6, can dismantle through connecting rod 7 between valve rod 3 and the instruction induction system 6 and be connected.
In this embodiment, the bottom of the connecting rod 7 can be in threaded connection with the top of the valve rod 3, the top of the connecting rod 7 is inserted on the indication sensing device 6 and is connected through the locking nut, the connecting mode is convenient to disassemble and assemble, and the fixing effect is reliable.
The inner side and the outer side of the dust cover 2 are both provided with heat insulation layers.
Because the dust cover 2 of the valve is a closed space and is positioned in a person-smoking rare area such as a desert and the like, the temperature in the dust cover can quickly rise to the extent of damaging the indicating induction device 6 or the limit switch annunciator 5 under the illumination effect. This embodiment is through setting up the heat insulating layer in dust cover 2 inside and outside, and the accurate molding influence to the valve switch position of high temperature in the avoidance cover that can be better.
Still to the problem of rising temperature in the cover, as shown in fig. 2, be provided with the subassembly that adjusts the temperature in the dust cover 2, the subassembly that adjusts the temperature includes the refrigeration piece 8 of embedding dust cover 2 and the treater 9 of being connected with refrigeration piece 8, and the heat-absorbing surface of refrigeration piece 8 is located the dust cover 2 inboard, and the cooling surface of refrigeration piece 8 is located the dust cover 2 outside, is provided with temperature sensor 10 on the treater 9.
This embodiment is through embedding refrigeration piece 8 on the cover wall at dust cover 2, and with cover in installation treater 9, detect to feed back to treater 9 after the temperature is higher than the setting value in the cover when temperature sensor 10, and start by treater 9 control refrigeration piece 8, 8 circular telegrams of refrigeration piece can be with covering interior heat absorption and arrange outside covering, the temperature is in the relatively stable scope in can real time regulation and control cover, its cooling and temperature control effect are better, the operational environment who instructs induction system 6 and limit switch annunciator 5 has effectively been improved.
The top of dust cover 2 is provided with photovoltaic board 11, and the subassembly that adjusts the temperature, position switch signal ware and instruction induction system 6 all can be connected with photovoltaic board 11 electricity.
