Abstract
The utility model relates to a reliable, small blind area and self-closing type device for indicating liquid level, the upper and the lower parts of which are two same combination valves, the combination valve is composed of a ball valve and a self-closing valve, and the middle part is a liquid level indicating member composed of a safety glass tube and a float; a flow channel composed of a bedding and a seal ring is arranged between the combination valve and the safety glass tube, and the upper and the lower combination valves are connected by a connecting sleeve and a jacket. The utility model assembles the ball valve and the self-closing valve into a same valve body, so the blind area is reduced; the safety glass tube is used, so when broken the safety glass tube becomes many chippings, and the self-closing valve is reliably closed.
Description
The utility model relates to a kind of fluid level gauge, and its liquid level indication blind area is less, and has the function of reliably closing automatically concurrently.
The structure of the Chinese utility application 89211524.6 of existing self-chosing indicator for fluid level is: glass tube backs down upper and lower two self-closing valves, keeps the liquid road unimpeded.When glass tube was disrumpent feelings, the piston in the self-closing valve lost the anchorage force of glass tube and is shifted under the effect of the yellow power of bullet, and the liquid road is closed.Such fluid level gauge has two significant disadvantages: one of shortcoming is because self-closing valve is installed on the stop valve.The certain space position that accounts for, thus glass tube finding length is reduced, make the blind area of fluid level gauge bigger; Two of shortcoming is in some cases, only occurs the crack during glass tube breaks, or local broken hole, and damaged part still has enough anchorage forces to withstand piston, and self-closing valve can not cut out, and causes leakage.
For first kind of shortcoming, the solution of China's utility application 93225578 is that through self-closing guiding valve is set, to reduce the blind area, but this structure is because the moving component of stop valve and self-closing valve is crossing, must on the guiding valve of lengthening, increase slotted eye, so that therefrom pass through by valve rod.The guiding valve materials of lengthening are many, process slotted eye on guiding valve, increased machining amount, thereby cost is increased.
The purpose of this utility model provide a kind of simple in structure, cost is low, the little blind area of the reliable type self-chosing indicator for fluid level that can reliably close automatically.
The purpose of this utility model is achieved in that
1. on one-piece construction, the utility model is upper and lower to be two identical combination valves of being made up of ball valve and self-closing valve (1), and the centre is the liquid level display unit formed of tempered glass pipe (4) and buoy (2) and the flow channel of equalizing bed (5) and O-ring seal (3) composition.Combination valve (1) is connected with sheath (6) by coupling sleeve (7) up and down.Owing to taked above unitized construction, under normal circumstances, tempered glass pipe (4) backs down self-closing valve (8) by equalizing bed (5), can correctly indicate liquid level.When tempered glass pipe (4) was impaired, self-closing valve (8) lost anchorage force and closes the cut-out flow channel rapidly owing to the tempered glass pipe becomes fragment in moment.
2. on combination valve (1) structure, Ball valve (9) and self-closing valve (8) are placed in the same valve body, and ball-valve structure is placed valve body one side, avoid the movement locus of self-closing valve (8), self-closing valve (8) is moved down, dwindle the blind area.
3. glass tube is heated in 500～600 ℃ of temperature ranges,, carry out tempering and handle then with the certain speed cooling.Glass tube behind the tempering can become fractionlet moment when impaired.
Owing to take above-mentioned technology incidence of criminal offenses, the purpose that reached simple in structure, cost is low, can reliably close automatically.
Owing to take technique scheme, the utility model product following points are better than like product:
1. solved in the like product self-closing valve in some cases, withstood by damaged glass tube and the problem that can not close.Thereby guaranteed when glass tube is damaged, can close immediately the purpose of flow channel really, avoided the loss of the liquid of storing.
2. simplify the structure,, save 1/3rd material with the like product ratio.
With 89211524.6 utility application relatively, the blind area reduces to 80 millimeters by original 140 millimeters.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model structural map.
1. combination valves, 2. buoys, 3. O-ring seals, 4. tempered glass officials, 5. equalizing beds, 6. sheaths, 7. coupling sleeves, 8. self-closing valve 9. Ball valves 10. plug screws among the figure
Tempered glass pipe (4) has formed the mechanical system of exerting pressure to the centre in two ends after backing down self-closing valve (8) among Fig. 1, and this system makes the sealing gasket compressive deformation, thereby seals.
Plug screw (10) adopts semicircle keyway, processes easily than hexagonal in adopting, than adopting outer-hexagonal to save material
Claims (3)
1. the little blind area of reliable type self-chosing indicator for fluid level, it is characterized in that: it is upper and lower to be two identical combination valves of being made up of ball valve and self-closing valve, the centre is the liquid level display unit that tempered glass pipe, buoy are formed, the flow channel of being made up of equalizing bed and O-ring seal between combination valve and tempered glass pipe, upper and lower combination valve is connected with sheath by coupling sleeve.
2. the little blind area of reliable type according to claim 1 self-chosing indicator for fluid level is characterized in that: what assemble between the described self-closing valve is the tempered glass pipe.
3. the little blind area of reliable type according to claim 1 self-chosing indicator for fluid level is characterized in that: the shutoff of described combination of valve body is a plug screw, and an end of plug screw is a cylindrical pit, and the other end is semicircle keyway.
