Abstract
The utility model relates to fire control water supply equipment which is a signal monitoring valve of fire control water supply mainly consisting of a valve body, a valve base, a valve clack, a valve sealing cover, a valve stem, a signal box and a hand wheel. One end of the valve stem is fixed with the hand wheel, while the other end of the valve stem is connected with the valve clack through the signal box and the sealing cover, and a supporting set is arranged between the signal box and the sealing cover to fix the interval, and a signal transfer device in the signal box comprises a regulating block and a microswitch, wherein, the regulating block is connected on the valve stem by screw thread, and the corresponding end surface of the regulating block is a bevel, and the microswitch is fixed on the limited bracket, a contact of the microswitch is correspondingly contacted with the bevel of the regulating block. The utility model has the advantages of simple whole structure, large adjustable range of the valve switch signal transfer and simple and convenient signal transfer assembly and debugging and maintenance.
Description
Technical field
The utility model belongs to fire water-supply control appliance technical field, promptly a kind of fire water-supply signal monitoring valve.
Background technology
In the past, fire supply system is mounted in the valve of water flow indicator front, because switch do not have tangible sign or signal, the realization remote monitoring that links of more impossible and fire fighting monitoring chamber causes hidden fire-fighting danger or unnecessary loss easily.As, the improper valve closing that causes of manual operation is lacked of proper care, in case breaking out of fire, water supply system loses due effect, can bring about great losses for the country and people's lives and properties.Along with the fire-fighting development of career has visuality, the valve of remote monitoring comes out.But the volume that these products have is big; The gear drive of passing through that has realizes the signal conversion, and their shortcoming is complex structure, cost height, the production difficulty is big, Installation and Debugging are difficult, signal conversion adjustable extent is little.
Summary of the invention
The purpose of this utility model be provide in order to overcome the deficiencies in the prior art a kind of simple in structure, signal conversion range big, process Installation and Debugging and keep in repair easy fire water-supply signal monitoring valve, to satisfy user's demand.
This purpose is achieved in that this fire water-supply signal monitoring valve, it is mainly by valve body, there is valve seat the valve body center, flap is arranged on the valve seat, and valve body capping, valve rod, the signal box, handwheel is formed, wherein valve rod one end and handwheel are fixed, its other end passes the signal box, flap in valve body capping and the valve body is connected, it is separated by fixing by support member between signal box and the valve body capping, in the signal box chromacoder is arranged, described chromacoder is mainly by microswitch, be used to control the regulating block of microswitch, limiting bracket and indicator lamp constitute, wherein microswitch is fixed on the limiting bracket, and regulating block is threaded on the valve rod.Described regulating block one end face becomes the inclined-plane, the contact corresponding contact of its inclined-plane and microswitch.
Chromacoder of the present utility model be by on valve rod with regulating block, limiting bracket and the microswitch that is conditioned with it constitute, make this monitor valve have the characteristics of far distance automatic monitoring, and also have simple in structure, production cost is low; Valve switch scope big (signal conversion stroke is big); The reliability height; Installation and Debugging and and simple and convenient for maintenance.
Description of drawings
Following accompanying drawing has provided embodiment of the present utility model.
Fig. 1 is the utility model overall structure half sectional view.
Fig. 2 is the circuit working schematic diagram of signal adapter.
The specific embodiment
1, the 2 pair of overall structure of the present utility model and operation principle thereof are described in more detail in conjunction with the accompanying drawings: as shown in Figure 1, this fire water-supply signal monitoring valve includes valve body 1, be equipped with on valve seat 3, the valve seat 3 in valve body 1 interior centre flap 2, flap 2 is connected with handwheel 7 by valve rod 5, and slide in the inner chamber of valve seat 3, drive its knee-action by valve rod 5.The upper port of valve body 1 is connected and fixed by valve body capping 4 sealing and by bolt, and there is sealing nut 12 sealing and fixing in addition once more the capping top in addition.On the coupling part of flap 2 and valve rod 5 guide pin bushing 13 is housed, in order to guarantee only to move up and down at the situation lower Disc that valve rod rotates, and not with its rotation, so be added with stop screw 14 on the guide pin bushing 13.Support by two support sets 15 between signal box and the valve body capping and be connected.Chromacoders in the signal box 6 have regulating block 9, limiting bracket 10, the microswitch 8 on inclined-plane by a side and red, the green indicator lamp (red light, a green light) that is connected on the microswitch constitutes.Regulating block 9 is threaded on the valve rod 5, contact 11 corresponding contact on its inclined-plane and the microswitch, and microswitch 8 is fixed on the limiting bracket.The two-way contact of switch by lead respectively with the signal box in and Control Room in traffic lights join.
In conjunction with the accompanying drawings 2, (and referring to accompanying drawing 1), the principle of signal conversion of this monitor valve is: when handwheel turned clockwise, the distance between flap and the valve seat reduced gradually, the flow by valve body also reduces thereupon, valve plays throttling action; Simultaneously, the rotation of valve rod makes on the regulating block and moves, and leans against the microswitch contact pressurized on the regulating block inclined-plane, reaches switch contact conversion behind the certain pressure, and red light is bright; When the distance between them equals 0, the valve Close All, current end, and at this moment valve plays the stop valve effect.When handwheel was rotated counterclockwise, the distance between flap and the valve seat increased gradually, also strengthened by the valve body flow thereupon, and regulating block moves down simultaneously, and when the pressure of microswitch contact was decreased to certain numerical value gradually, switch contact resetted, and green light is bright.The utility model adopts the interactively of regulating block and microswitch and designs the opening value of a given monitor valve.The effect of signal monitoring apparatus is exactly to control this value scope, and it is bright that just monitor valve is opened to above green light 17 ability of certain value scope.On the contrary, when valve opening less than opening value, flow is less than when setting value, the conversion of microswitch contact, red light 16 is bright, simultaneously, switching signal is delivered to the fire fighting monitoring chamber synchronously.Realized the purpose of remote monitor like this.Guarantee the reliability of fire water-supply.
