Abstract
The present invention relates to fire-fighting equipment technical field, more particularly, to be a kind of recoil simulator for fire valve.The recoil simulator that the present invention is used for fire valve includes support meanss, conveyer, device box, indicating member and instruction device.Conveyer is integrally in a cross-shaped mode, including for installing the driving section of indicating member, being installed on the symmetrical weight control device in driving section and two limiting sections moved up and down along support meanss, stabilization in connecting rod.Overall structure of the present invention is simple, and manufacturing cost is low, can stablize valve opening and closing status information being transferred to instruction device, makes operator's intuitively visual valve state.
Description
Technical field
The present invention relates to fire-fighting equipment technical field, more particularly, to be recoil simulator for fire valve.
Background technology
For the open/close states of intuitive judgment fire valve, valve is typically provided for showing valve opening and closing state and alarm
Deng the recoil simulator of fine motion control.Majority signal device is mostly independent one on the market, then is installed on using turbine conveyer
On valve, a variety of worm gear combination transmissions, limited by the precision of whirlpool tooth on worm gear, easily produce error, precision is poor, and structure
It is complicated.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of recoil simulator for fire valve.
To achieve the above object, technical solution of the invention is：For the recoil simulator of fire valve, the fire-fighting
Valve includes connecting rod and valve body.The present invention includes device box, instruction device, conveyer and indicating member, instruction device peace
Before device box.Curved support device is provided with above the valve body, connecting rod is connected through support meanss with valve body, device
Box is installed on before support meanss；Conveyer is located in support meanss, and conveyer includes driving section and is set in connecting rod
Connecting portion, connecting portion is fixedly connected with the connecting rod, and conveyer rotates lifting with connecting rod and moved up and down；Described device box
Below, the groove with driving section diameter matches is provided with separately below；Transmission portion is in device box, and driving section is above and below in groove
Mobile, indicating member is installed on above driving section.Directly indicating member is fixedly connected with the connecting rod by a conveyer,
The error of the open/close states that effectively solve to bring by worm gear conveyer, signal triggering etc., heighten the precision, steady of recoil simulator
It is qualitative；And overall structure is simple, material is saved.
Preferably, the conveyer also includes the weight control device behind the connecting portion, weight control device with
Driving section is symmetrical.It is sagging because of driving section deadweight after weight control device can avoid recoil simulator long-term use, cause to pass
Send device connecting portion to be connected loosening with connecting rod, influence the accurate and stable delivery of signal.
Embodiment
The present invention is further illustrated below in conjunction with specific embodiment.
The direction term being previously mentioned in the present invention, such as：It is upper and lower, forward and backward etc., only it is the direction of reference explanation book, with dress
Put before box relative support device is.Therefore, the direction term used is intended merely to illustrate, is not used for limiting the present invention.
The present invention is used for the recoil simulator of fire valve, and the fire valve includes connecting rod and valve body.The present invention includes
Device box, instruction device, conveyer and indicating member, instruction device are installed on before device box.It is provided with above the valve body
Curved support device, connecting rod are connected through support meanss with valve body, and device box is installed on before support meanss.It is of the invention overall
It is simple in construction, save material.
Conveyer is located in support meanss, and conveyer includes driving section, is set in the connecting portion of connecting rod and is located at
Weight control device behind connecting portion, and two limiting sections for being respectively arranged on connecting portion both sides.The transmission of the conveyer
Portion, connecting portion, weight control device and limiting section, which are integrated, to be made, and overall structure is simple, and manufacturing cost is low.The connecting portion with
Connecting rod is fixedly connected, and conveyer rotates lifting with connecting rod and moved up and down；Behind described device box, separately below it is provided with
With the groove of driving section diameter matches；Transmission portion is in device box, and in being moved up and down in groove, indicating member is installed for driving section
Above driving section.Weight control device is symmetrical with driving section；Weight control device can avoid recoil simulator from making for a long time
It is sagging because of driving section deadweight with rear, cause conveyer connecting portion to be connected loosening with connecting rod, influence signal it is accurate with it is steady
It is fixed to transmit.The outer face of the limiting section is provided with the inner groovy of longitudinal direction；The madial wall of the support meanss is provided with and inner groovy
The longitudinal interior raised line matched somebody with somebody；The inner groovy of the conveyer moves up and down along interior raised line.It will directly be referred to by a conveyer
Show that unit is fixedly connected with the connecting rod, the mistake for effectively solving the open/close states, the signal triggering that are brought by worm gear conveyer etc.
Difference, heighten precision, the stability of recoil simulator.Two limiting section shapes of a lateral H shape simultaneously, can be further assured that conveyer
It is consistent to move up and down direction, transmits status signal etc. more stable.
The indicating member is plastic material, mitigates the load-bearing of conveyer.
Present invention additionally comprises the micromotion structure being installed in device box, the side of micromotion structure is provided with microswitch；Work as biography
Send and moved on device when being adapted to height with micromotion structure, microswitch contacts at the side of indicating member.Microswitch can be with disappearing
Other modules of anti-valve, such as the connection such as warning system or central control system.When the signal of indicating member gets over high precision, fine motion is opened
The signal of pass is also sensitiveer, stably.
Convex horizontal line together is provided with before the indicating member；Indicating member moving range is provided among the instruction device
The batten matched somebody with somebody；Batten is transparent material；The both sides that instruction device is located at batten indicate scale.The driving section is provided with screw；Institute
The bottom for stating indicating member is provided with the screw rod matched with screw, and indicating member is threadedly coupled with driving section.Screw rod and spiral shell can be passed through
The position of indicating member is finely tuned in hole, signal is matched with the scale of instruction device.And make to pacify between indicating member and driving section
Dress is convenient.
It is above-described, only presently preferred embodiments of the present invention, it is impossible to limit the scope of this practicality implementation, it is every according to
The equivalent change and decoration that scope of the present invention patent is made, it should all still fall within the range of the present invention covers.
