Description
Technical field
The utility model belongs to valve field, is related to worm wheel head, especially a kind of signal mode transmission worm wheel head.
Background technique
Worm wheel head is the mechanism of control valve unlatching and rate-of flow, and traditional worm wheel head only has in-situ calibration, without remote
Function is passed, cannot understand the particular state of valve in Central Control Room, if someone malfunctions valve, operator is difficult to find, meeting
Situations such as causing device to stop.
The use of some materials supplies consumption under specific operation is minimum in Chemical Manufacture, and the control of hand valve is difficult to find most
Low consumption point needs to buy regulating valve, but regulating valve somewhat expensive, for some valves infrequently acted, uses regulating valve
It is uneconomical.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, a kind of signal mode transmission worm wheel head is provided,
The valve state teletransmission of worm wheel head to Central Control Room can be made operator's moment understand the state of valve, avoid someone's malfunction
Make, while production run can be optimized, reduces supplies consumption.
The utility model technical scheme applied to solve the technical problem is:
A kind of signal mode transmission worm wheel head, including shell, cap, worm gear and worm screw, worm gear and worm screw engagement in shell
Connection, the worm screw outside shell are fixedly mounted with handwheel, are fixedly mounted with worm gear signal indicator, the signal indicator packet in cap top surface
Two cams, support rod, two contact-making switches, connecting terminal, instruction disk, instruction disk housing, upper cover are included, support rod passes through chassis
It is fixedly mounted with worm gear, on the top of support rod, suit fixes two cams, and two cams are alternatively arranged up and down, and each correspondence of two cams one connects
Touching switch, two contact-making switches are mounted on upper tops by bracket, and the upper cover is packed in cap top surface, contact-making switch be fixedly mounted with
Connecting terminal on upper lid is connected by conducting wire, and the outlet of connecting terminal enters upper cover from the Top Leading-out Hole of the top plate of upper cover
It is interior, and drawn from the side outlet hole of upper cover side wall, it is connect with Central Control Room, is coaxially fixedly mounted with an instruction disk on the top of support rod,
Indicate that pointer is installed in the side of disk, pointer lower part is fixedly mounted with upper cover, and an instruction disk housing is fixedly mounted with above upper cover.
Moreover, the ring wall uniform intervals in support rod are formed with multiple worm gear location holes, cam and support rod by that will position
Bolt insertion location hole is connected and fixed.
Moreover, being respectively marked with scale above each worm gear location hole.
The advantages and positive effects of the utility model are as follows:
1, there are two cams for this worm wheel head, can indicate the switch of the high limit and lower bound or valve of valve, reduce adjusting
The frequency of positioning bolt.
2, the state of valve can be transferred to Central Control Room by this worm wheel head, can be monitored valve state constantly, be avoided someone
Malfunction.
3, this worm wheel head has multiple worm gear location holes, can be controlled according to the required aperture of valve site, simple side
Just.
Detailed description of the invention
Fig. 1 is the main view of this worm wheel head；
Fig. 2 is the internal structure chart (removing cap) of this worm wheel head；
Fig. 3 is the A-A of Fig. 1 to cross-sectional view；

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of signal mode transmission worm wheel head, including shell 1, cap 2, worm gear 9 and worm screw 3, worm gear and worm screw in shell
Engagement connection, the worm screw outside shell are fixedly mounted with handwheel 4, are fixedly mounted with worm gear signal indicator in cap top surface, the signal refers to
Show device include two cams 10,12, two contact-making switches 11 of support rod, connecting terminal 13, instruction disk 6, instruction disk housing 7, on
Lid 5, support rod are fixedly mounted with by chassis 15 with worm gear, and on the top of support rod, suit fixes two cams, and two cams are between the upper and lower every row
Column, two cams, one contact-making switch of each correspondence, two contact-making switches are mounted on tops by bracket 14, and the upper cover is packed in
Cap top surface, contact-making switch are connect with the connecting terminal being packed on upper lid by conducting wire, and the outlet of connecting terminal is from upper cover
The Top Leading-out Hole 16 of top plate enters in upper cover, and draws from the side outlet hole 8 of upper cover side wall, connect with Central Control Room.In support rod
Top be coaxially fixedly mounted with an instruction disk, instruction disk side install pointer 17, pointer lower part is fixedly mounted with upper cover, in the upper of upper cover
