Abstract
The utility model relates to a clutching self-close valve which does not need a dynamic force power supply and is opened by hand. The electric power consumption of the utility model is little, and the utility model can be automatically closed. The utility model is provided with a valve body and a valve rod on which a clutch is sheathed. The clutch is composed of a casing, wherein, the corresponding position of which is provided with a bar-shaped hole, an upper cover, a speed change mechanism fixed in the casing, a gear sector which is arranged in the casing and is connected with the speed change mechanism, a gear rack which is abutted with the gear sector, and a manual rod which is cooperated with the gear rack and is led by the upper cover. The upper end of the manual rod is provided with a handle on which a ratchet wheel is arranged. The gear rack and the bar-shaped hole are parallel. The front part of the gear rack is provided with a plug hole. The valve rod penetrates through the plug hole and the bar-shaped hole.
Description
The utility model relates to the self-closing valve of a kind of clutch type.
Existing electric valve switch power will have motor to provide, and the state that solenoid valve opens or closes will lean on coil electricity to form electromagnet and keep, and power consumption is all higher.
The purpose of this utility model is to provide a kind of and need not electrical source of power and the self-closing valve of power consumption clutch type little, manually opened, that close automatically.
The utility model is achieved in that it has a valve body, valve rod, on valve rod, be set with clutch, said clutch is had a bar hole by corresponding position housing and loam cake, be fixed on gear in the housing, be placed in the housing tooth bar that leans on mutually with the joining tooth fan of gear, with the tooth fan and match and merge the manual rod of drawing and constitute by loam cake with tooth bar, handle is equipped with in said manual rod upper end, and ratchet is housed on the handle, said tooth bar parallels with bar hole, in the tooth bar front portion jack is arranged, said valve rod passes this jack and bar hole.
The self-closing valve of above-mentioned clutch type is equipped with Returnning spring on valve rod, the other end of said Returnning spring is fixed on and covers.
The utility model has the advantages that manually opened, close automatically, reliability is high and do not need electrical source of power.Owing to do not need electric power that switch valve power or maintenance valve state are provided, can reduce power consumption to greatest extent, be specially adapted to systems such as water supply system, hydraulic pressure.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view that the utility model removes loam cake.
Embodiment of the present utility model is provided below:
This self-closing valve has a valve body 1, valve rod 10, on valve rod 10, be set with clutch, the housing 2 of said clutch, with valve rod 10 corresponding positions bar hole 2a is arranged on the loam cake 3,3a, said clutch is fastened on the valve body 1 by screw rod and nut 12, a motor cabinet is arranged on loam cake 3, at this motor cabinet internal fixation motor 5 is arranged, the speed change gear group 13 that links with motor output shaft 14 is housed in housing 2, said motor 5, motor output shaft 14 and gear train 13 constitute gear, in housing 2, be placed with the tooth fan 15 that is meshed with speed change gear 13 in the gear, be placed with tooth bar 11 along bar hole 2a direction and with bar hole 2a corresponding position, in tooth bar 11 front portions a through hole is arranged, said valve rod 10 passes this through hole and bar hole 2a, 3a, on valve rod 10, also be set with Returnning spring 6, the other end of Returnning spring 6 is fixed on the loam cake 3 by the screw 4 that connects loam cake 3 and housing 2, said tooth bar 11 also leans on mutually with tooth fan 15, corresponding tooth bar 11 tooth top positions have a relative up and down fairlead and jack respectively on loam cake 3 and housing 2, on this jack, be fitted with manual rod 8, the lower end of said manual rod 8 is gear shape and matches with tooth bar 11, handle 9 is drawn and be equipped with in the upper end of said manual rod 8 thereon by fairlead, ratchet 7 (said ratchet 7 also can be contained on the loam cake 3) is housed in handle 9.
During work, clutch is by just or oppositely instantaneously finish the clutch conversion to electricity.
When this valve was in normal opening state, valve rod 10 was in the enable possition, and electric clutch is in closed state, tooth bar 11 and manual rod 8 are meshed, because of the effect of ratchet 7, make the self-insurance state after manual rod 8 is in unlatching, Returnning spring 6 is in the energy storage state.
Close the valve process: clutch was got by control wiring control moment, make the gear action, making tooth fan 15 forwards (clockwise) rotates, tooth fan 15 is no longer pressed tooth bar 11, then tooth bar 11 is become by engagement with manual rod 8 and separates, in Returnning spring 6 and valve, under the impact force action of medium, drive valve rod 10 and get back to closed condition.Keep closed condition need not switch on.
Open the valve process: clutch is by control wiring control reverse getting of moment, by the gear counteragent, make tooth fan 15 backward rotation, and hold out against tooth bar 11, make tooth bar 11 and manual rod 8 be in engagement again, by turning handle 9, tooth bar 11 is moved to the left, and valve rod 10 is swung left, promptly open valve, open in the valve process, Returnning spring 6 enters normal opening state because of the deformation energy reserve.Simultaneously, prevent that by ratchet 7 manual rod 8 from just changeing.Therefore, be held open state, clutch need not switched on.
Claims (2)
1, the self-closing valve of a kind of clutch type, comprise valve body, valve rod, it is characterized in that, on valve rod, be set with clutch, said clutch is had the housing and the loam cake of bar hole by corresponding position, be fixed on the gear in the housing, be placed in the housing and fan with the joining tooth of gear, the tooth bar that leans on mutually with tooth fan and match with tooth bar and to merge the manual rod of drawing and constitute by loam cake, handle is equipped with in said manual rod upper end, and ratchet is housed on the handle, said tooth bar parallels with bar hole, in the tooth bar front portion jack is arranged, said valve rod passes this jack and bar hole.
2, the self-closing valve of clutch type according to claim 1 is characterized in that, Returnning spring is housed on valve rod, and the other end of said Returnning spring is fixed on and covers.
