Description
(1) technical field: the device that the present invention relates to control valve switch on gas pipeline; Be specifically related to a kind of gas meter motor switch valve.
(2) background technique: in prior art, for the gas meter motor switch valve of gas pipeline, is that the linear reciprocation formed by screw-driven by its Electric actuator drive nut and screw rod is moved, realizes the unlatching to gas valve or closedown.Due to the nut of screw-driven and screw rod requirement on machining accuracy higher, in production, Chang Yin does not reach the requirement on machining accuracy of setting, when making the nut driven in work drive screw rod to carry out shuttle switch valve, easy generation nut and screw driven " blocking not " phenomenon, can not complete the switch of valve immediately accurate, reliable and stablely according to the control of civil gas management department.Usually there is following defect: one is can not Open valve immediately, seriously have impact on the normal air feed of resident; Two is immediately can not carry out valve closing, causes to stop the resident of air feed by throttle down at once, still gratis continues to use combustion gas, causes certain economic loss to civil gas management department.
(3) summary of the invention: the deficiency existed for above-mentioned prior art, the object of the present invention is to provide a kind of gas meter motor switch valve, be intended to realize switch valve rapid sensitive, accurately and reliably, so that ensure the normal air feed of resident and reduce the economic loss of civil gas management department.
For achieving the above object, technological scheme of the present invention is achieved in that this gas meter motor switch valve, mainly comprises the reduction gear that valve body motor-driven connects; It is on the sleeve outer circle of body cavity locating support, be rotatably connected with ratchet circle gear; The tooth bar of the controlling rod that described ratchet circle gear is connected on locating support with elasticity engages; Be built-in with ratchet bracket at the counterbore of described ratchet circle gear, described ratchet bracket is rotatedly connected by the rotating shaft of its lower end and the axle sleeve hole of described locating support; The guiding groove of ratchet slides and is connected on the positioning shaft of ratchet bracket; The correspondence of locating tooth up and down of described ratchet engages with the internal tooth of described ratchet circle gear or is separated; Described ratchet engages with ratchet gear.
When implementing technique scheme, the present invention selects to be provided with locating tooth usually on the end face of shaft bush of described locating support, and the locating tooth that described locating tooth is provided with ratchet bracket lower end surface engages.
When implementing technique scheme, the present invention can also select the rotating shaft of described ratchet bracket lower end to be inverted cone opening shape.
The present invention is by taking said structure, during work, in the moment that ratchet gear driving pawl rotates, namely the locating tooth of described ratchet is separated engagement with the internal tooth of ratchet circle gear, act on the elastic force on controlling rod, by the rack drives ratchet circle gear of the controlling rod lower end sleeve outer circle quick rotation along locating support, the Sealing that controlling rod front end is connected with launches closedown valve of gas pipeline very fast.Civil gas management department achieves control valve switch rapid sensitive, accurately and reliably.Opened by instant control valve, effectively ensured the normal air feed of resident; The corresponding instant control valve of the resident of air feed that stops is closed, and significantly reduces the economic loss of civil gas management department.
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.

(5) embodiment: shown in Fig. 1-Figure 14.This gas meter motor switch valve, mainly comprises multiple reduction gear that valve body motor 8 is in transmission connection; It is on the sleeve outer circle of body cavity locating support 7, be rotatably connected with ratchet circle gear 4; Described ratchet circle gear is engaged with the tooth bar of the controlling rod 2 be connected on locating support by spring 3 elasticity; Be built-in with ratchet bracket 9 at the counterbore of described ratchet circle gear, described ratchet bracket is rotatedly connected by the rotating shaft of its lower end and the axle sleeve hole of described locating support; The guiding groove of ratchet 6 slides and is connected on the positioning shaft of ratchet bracket 9; The correspondence of locating tooth up and down of described ratchet 6 engages with the internal tooth of described ratchet circle gear 4 or is separated; Described ratchet engages with ratchet gear 10 (shown in Fig. 8, Fig. 9, Figure 10).
The end face of shaft bush of described locating support 7 is provided with locating tooth, and the locating tooth that described locating tooth is provided with ratchet bracket 9 lower end surface engages; The rotating shaft of described ratchet bracket lower end is inverted cone opening shape (shown in Figure 13, Figure 14).
During work, ratchet gear 10 of the present invention is engaged with the duplex reduction gear 5 be in transmission connection by valve body motor 8 (shown in Fig. 1-Fig. 3), when ratchet gear 10 rotates counterclockwise the guiding groove driven on ratchet 6, when positioning shaft upward sliding location along ratchet bracket 9 stops, the upper locating tooth of ratchet 6 and the internal tooth of ratchet circle gear 4 are in engagement (shown in Fig. 4, Fig. 8).Now drive the upper locating tooth of ratchet 6 to stir ratchet circle gear 4 by ratchet gear 10 to rotate, the elastic force pulling the tooth bar of controlling rod 2 to overcome spring 3 moves down, and valve of gas pipeline is opened (shown in Fig. 8) by the rubber seal 1 that controlling rod front end is connected with.
When civil gas management department sends control command throttle down, the duplex reduction gear 5 be in transmission connection with valve body motor 8 drives ratchet gear 10 to rotate clockwise (shown in figure 8), in the moment that driving pawl 6 rotates, namely the upper locating tooth of described ratchet is separated engagement with the internal tooth of ratchet circle gear 4.Now act on the elastic force of the spring 3 on controlling rod 2, by the ratchet circle gear 4 that the rack drives engagement of controlling rod lower end is connected, along the sleeve outer circle quick rotation of locating support 7 under the condition of non-loaded resistance, the rubber seal 1 that controlling rod front end is connected with launches very fast closes valve of gas pipeline (shown in Fig. 9), ratchet gear 10 continues to rotate clockwise the guiding groove driven on ratchet 6, when positioning shaft slide downward location along ratchet bracket 7 stops, the lower locating tooth of ratchet 6 and the internal tooth of ratchet circle gear 4 are in engagement (Fig. 1, shown in Figure 10), complete the sealing self-locking after valve closing.Now valve body motor 8 quits work.
In work, when the rotating shaft of ratchet gear 10 ratchet bracket 9 lower end be made up of engineering plastics that drives ratchet 6 to stir, (Fig. 4 when rotating in the axle sleeve hole of locating support 7, Figure 13, shown in Figure 14), the end face of shaft bush locating tooth of the locating tooth relative positioning support 7 of described ratchet bracket 9 lower end surface, all the time be in and engage to tooth top by the bottom of tooth---the working state of separation, the micro-axial reciprocating displacement from low to high produced, by the resiliently deformable of ratchet bracket 9 inverted cone opening rotating shaft in locating support 7 axle sleeve hole, carry out the adjustment of micro-axial reciprocating displacement in time, accurately and reliably engage with the locating tooth up and down better realizing described ratchet 6 with the internal tooth of ratchet circle gear 4 or be separated.
Above-mentioned is only the preferred embodiment of the present invention.Be noted that for those of ordinary skill in the art; with substantially identical means; realize substantially identical function; reach substantially identical effect; without the need to other technical characteristics just obviously associated through creative work; can also replace the modification and/or improvement of making several basic same way, these changes should be considered as equivalent feature, within the protection domain all belonging to patent of the present invention.
