Abstract
The utility model relates to a limit device of liquid level. The limit device of liquid level overcomes the disadvantages that present liquid level limit valves have complicated and heavy structure, short service life, and the liquid level limit valves must be matched with specific containers. The limit device of liquid level is characterized in that a control valve is arranged in a circular through hole at the center of a float, the upper end of the through hole is connected with a water inlet pipe, the lower end of the through hole is connected with a liquid storage container, a hollow valve plug which can move in the through hole is sealed in the through hole, and the lower part of the valve plug is connected with a heavy hammer via strings. When the strings are loosened, the limit device of liquid level can rise with liquid level until the strings are tensioned to close the valve, and thus the aim of automatically limiting the height of liquid level can be obtained. The limit device of liquid level can be particularly utilized as the accessory of a water storage container.
Description
The utility model relates to a kind of liquid level stop means, and it is made up of valve body and valve operation valve and float stifled and that control section is formed.
The liquid level stop means that utilizes buoyancy to open and close at present all adopts ball float, the structure that connecting rod opens and closes.This complex structure and heaviness, part is easy to wear, and must use in the special container that matches with it.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of simple and light, and part is not easy to wear, long service life and be applicable to the liquid level stop means that uses in difform storage liquid container.
The purpose of this utility model is achieved in that the utility model is stifled by valve body and valve and control section is formed operation valve and float form, and it is characterized in that having a garden shape through hole in the float centre, and operation valve is arranged in through hole.The hose adapter that links to each other with water supply hose is housed in the through hole upper port, lower port is connected to valve body, hose adapter and valve body combine by the mode and the float of thread connection, garden shape passage is vertically arranged on hose adapter and valve body, the hollow rubber ball valve of packing in the shape through hole of garden is stifled, the stifled diameter of valve is bigger and can be free movable in the shape through hole of garden than the diameter of the garden shape passage on hose adapter and the valve body, is connected with a flexible connecting line on valve is stifled, and the other end of line links to each other with a weight.
During use, the length of the flexible connecting line according to the good valve of height control of required liquid level in the storage liquid container between stifled and weight, the liquid output pipe mouth and the hose adapter that will have switch with flexible pipe link together, this liquid level stop means is placed the storage liquid container, after opening switch, liquid level is lower in the storage liquid container, when flexible connecting line is in relaxed state, this stop means raises with the rising of liquid level, till when line is tightened, this moment is because the action of gravity of weight itself makes valve stifled with the garden shape pathway closure on the valve body, thereby the liquid level in the storage liquid container is no longer raise, can reach the effect of restriction liquid level thus.
The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:
In the accompanying drawing:
Fig. 1 is the utility model structure cut-open view
Fig. 2 is the utility model vertical view
Fig. 3 is the utility model upward view

This stop means has the float 8 of garden shape through hole 7 by central part, hose adapter 1, and through hole lining 2, valve is stifled 3, valve body 4, nylon rope 5 and weight 6 are formed.Float 8 is bowl-shape, use the non-toxic polyvinyl chloride blow molding, 120 millimeters of its upper surface external profile diameters, high 60 millimeters, 20 millimeters of garden shape through hole 7 diameters, 20 millimeters of one external diameters are housed in through hole 7, the through hole lining 2 that wall thickness is 1.5 millimeters, between lining 2 and the float 8 for movingly, the two ends up and down of lining 2 are connected by screw thread with hose adapter 1 and valve body 4 respectively, to form an external garden diameter respectively be 30 millimeters having male-pipe wall part lower end on externally threaded that part of tube wall upper end and the valve body 4 on the hose adapter 1, and thick 2 millimeters regular hexagon bead makes this stop means become as a whole so that will above-mentionedly be threaded after partly tightening.Through hole lining 2, hose adapter 1 and valve body 4 are by the non-toxic polyvinyl chloride injection mo(u)lding.Garden shape channel diameter on hose adapter 1 and the valve body 4 is 10 millimeters, the shape passage upper port expansion of valve body garden is bell mouth shape, in lining 2, pack into the hollow rubber ball valve stifled 3 of 12 millimeters of diameters, the passage that the nylon rope 5 that is attached thereto is passed on the valve body 4 links to each other with following weight 6, nylon rope length is shorter than cistern height, attach most importance to 0.5 kilogram ceramic block of weight, this liquid level stop means is placed cistern, the other end that is connected in the delivery hose 9 on the hose adapter 1 is connected on the lock-on connection (Fig. 4 and Fig. 5) that is fixed on the effluent pipe mouth, open switch, this device can automatically be controlled at the water level in the cistern below the certain altitude.
The present invention compare original technology have simple in structure, easy to use, the characteristics that the life-span is long.
