Abstract
The utility model relates to an electric gas control valve, which is composed of a main valve body, an auxiliary valve body, a spherical valve core, a valve rod, a motor, etc. The utility model is characterized in that two separated four-fluorine valve seats are adopted for supporting the valve core in the main valve body; pre-stressing is supplied by the auxiliary valve body to the valve seats, causing that the valve core can be tightly embraced, forming two favorable seal lines; a sealing structure composed of a clamping ring, four-fluorine filling, a filling press cover and a press plate wit a right-angled limiting device is arranged between a valve rod, the valve core and the main valve body, causing that the utility model can has no leakage needing only a micromotor; the valve can be safely opened and closed; the structure is simple; the size is small.
Description
The utility model relates to a kind of gas control valve, particularly a kind of leak free electric gas control valve.
Existing gas control valve, special electric gas control valve, as the electromagnetism gas control valve, higher, dangerous owing to having adopted general sealing configuration commonly used to cause leakage rate, volume is big.
The purpose of this utility model is to overcome above-mentioned defective, and a kind of do not have leakage, safe and reliable, electric gas control valve that volume is little, simple in structure are provided.
The purpose of this utility model is achieved in that a kind of electric gas control valve, comprise main valve body, it is characterized in that the gas circuit in the main valve body is provided with a spherical valve core, spool by the centre have the left valve seat of pore, the clamping of right valve seat air-tight fit is placed on the gas circuit of main valve body, the airtight fastening auxiliary valve body that is connected with on a port of main valve body, an end and the left valve seat activity of auxiliary valve body in main valve body joined; Right valve seat embeds in the main valve body; One valve rod is arranged at spool top, and the valve rod upper end links by the output shaft of a coupling and a train of reduction gears; The input shaft of train of reduction gears and a motor link; The bottom of valve rod is with a collar, and collar top is placed with the tetrafluoro filler, and a Gland is arranged on the filler, is stamped pressing plate on the Gland, and pressing plate is provided with 90 ° of rotary limit devices of valve rod, and pressing plate and main valve body are linked by fastening piece.
90 ° of rotary stopper measures of valve rod are to have an axis hole with 90 ° of unfilled corners on pressing plate, and correspondingly valve rod is to cut away the rectangular oblique crank Z that two circles lack along diameter symmetry in the transverse section of this coupled position.
For sealing better, accompany one " O " shape seal ring between main valve body and the auxiliary valve body.
For dustproof, outside motor and train of reduction gears, be provided with a case that links with main valve body.
Because it is adopted said structure, the utility model can effectively stop to leak, safe and reliable, simple in structure, volume is small and exquisite, has realized the purpose of this utility model preferably.
Below in conjunction with accompanying drawing 1 to 3 and embodiment the utility model is done more careful description.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of pressing plate 9.
Fig. 3 is the sectional schematic diagram of valve rod 2.
The electric gas control valve, comprise main valve body 3, gas channels in the main valve body 3 is provided with a spherical valve core 13 the same with the spool of ordinary ball valve, spool 13 is placed on the gas channels of main valve body 3 by mutually airtight identical left and right valve seat 6,61 clampings of two the interior types and the external form of spool 13, on the left port of main valve body 3, be fastened with an auxiliary valve body 4, accompany one " O " RunddichtringO 5 therebetween with threaded connection mode; An end shape and valve seat 6 external forms that auxiliary valve body 4 puts in the main valve body 3 match, tighten auxiliary valve body 4 and give 6 one precompressions of valve seat, left and right two valve seats 6,61 are tightly embraced spool 13, and between left and right valve seat 6,61 and spool 13, form the two seals line, so sealing effect is fine, owing to have most suitable precompression so that spool 13 and left and right valve seat 6,61 to be unlikely tightly locking, therefore the required torque of rotational valve core 13 is little, only needs more than 100 milliampere motor just can make valve close reliably or open.One valve rod 2 is arranged at spool 13 tops, and the one end links with cylinder groove inserting mode and spool 13, and the other end of valve rod links by the output shaft of coupling and train of reduction gears 8, and the input shaft of train of reduction gears 8 then links with motor 7; For the bottom that is sealed in valve rod 2 is provided with a collar 12, collar 12 tops are filled with a pair of tetrafluoro filler 11, and tetrafluoro filler top is with a Gland 10, is stamped pressing plate 9 on the Gland 10, pressing plate 9 links by screw and main valve body 3, thereby valve rod 2 parts can not leaked; Also be provided with mechanical stop limiter on the pressing plate 9, even the axis hole of pressing plate 9 is the hole that has 90 ° of unfilled corners; Correspondingly make valve rod 2 cut away the rectangular oblique crank Z that two circles lack for symmetry, make that valve rod 2 can only 90 ° of rotations, thereby spool is merely able to positive and negative 90 ° of rotations, and make gas circuit reliably seal in the section configuration of this cooperation place; Other is provided with a case 1 and tightly links together by internal thread and main valve body 3, makes component such as motor 7 and train of reduction gears 8 be subjected to good protection; The common electric machine that motor can adopt 3-6V to drive.
