Abstract
The utility model relates to a fast safety connecting valve for liquid gas, which belongs to a connecting valve for liquid gas stoves. A connecting frame of a gas outlet pipe, which is combined with a push rod into a whole, is sheathed in an upper sleeve cover. A spring and a connecting seat are sheathed on the push rod in sequence, a press cap is sheathed on the connecting frame of a connecting pipe of the gas outlet pipe by the spring, and a positioning steel ball is inlaid in the inner margin of the press cap. A valve body is sheathed on the outer margin of the connecting frame of a gas inlet pipe, and valve cores which are provided with a sealing ring and a spring are arranged in the inner cavities of the valve body and the connecting frame of the gas inlet pipe. A lower sleeve cover is sheathed on the outer margins of the valve body and the connecting frame of the gas inlet pipe. When the upper sleeve cover and the lower sleeve cover are combined to a whole or are separated, the passage of the liquid gas is completely opened or closed.
Description
The utility model belongs to gas stove and connects valve.
Have a kind ofly on the market, be provided with the valve body of suction port and air outlet, the safety relief valve that glued membrane and valve lever constitute by valve cover, its simple structure can open and close automatically valve, but exists valve closing not tight, seal badly, shortcoming such as often have an accident.
The purpose of this utility model is to provide a kind of liquid gas fast and safely to connect valve.
The purpose of this utility model is to realize like this, constituting on the push rod of one with the steam outlet pipe link press span, the connecting base that is socketed with spring successively and seal ring is housed, push rod and steam outlet pipe link press span connecting part are provided with vent, the pressure cap that inner edge is inlaid with locking ball is connected on the steam outlet pipe link press span by spring housing, upper sleeve cover is socketed in the outer rim place of steam outlet pipe link press span, inner chamber at valve body, the spool that seal ring is housed places the inner chamber of suction tude by spring, the suction tude link press span socket-connects by seal ring and valve body, and lower sleeve cover and valve body and suction tude link press span socket-connect.
The utility model adopts the dock structure, be socketed with the steam outlet pipe link press span that constitutes one with push rod in the upper sleeve cover, on push rod, be socketed with spring and the connecting base that seal ring is housed successively, lower sleeve cover and suction tude link press span and valve body socket-connect, the spool of seal ring is housed, be placed in the inner chamber of valve body and suction tude link press span by spring, locking ball is embedded in the pressure cap inner edge groove, adopt said structure, the sealing and the Security that connect valve have been improved, during use upper sleeve cover and lower sleeve cover butt joint are integral, gas circuit is just linked up, not the time spent, upper sleeve cover and lower sleeve cover are separated, the vapour road is just blocked, must often not open or close the valve of hydraulic pressure vapour jar, and is easy to use.
Concrete structure of the present utility model is described further in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural drawing.
Push rod 3 constitutes one with steam outlet pipe link press span 1, its connecting part is provided with three vents triangular in shape 16, the connecting base 4 that spring 9 and inner edge stud with two seal rings 10 is socketed on the push rod 3 successively, the two ends of spring 9 respectively with steam outlet pipe link press span 1 and connecting base 4 on spring seat join, pressure cap 5 is socketed on the outer rim of steam outlet pipe link press span 1 by spring 11, three locking balls 12 are embedded in the groove of pressure cap 5 inner edges, upper sleeve cover is socketed in the outer rim place of steam outlet pipe link press span 1, the spool 7 that is with seal ring 13 places the inner chamber of suction tude link press span 8 by spring 14, the two ends of spring 14 join with the head of spool 7 and the spring seat of suction tude link press span 8 respectively, spool 7 places the inner chamber of valve body 6 simultaneously, seal ring 13 is equipped with at the top of suction tude link press span 8, and lower sleeve cover 15 is socketed in the outer rim place of valve body 6 and suction tude link press span 8.Working principle, when being integral when upper sleeve cover 2 and lower sleeve cover 15 are connected, valve body 6 is under the promotion of suction tude link press span 8, the locking ball 12 that is embedded in pressure cap 5 inner edges is snapped in the groove on valve body 6 tops, spring 11 is compressed, spool 7 contacts with push rod 3 and promotes the direction motion of spool 7 to suction tude link press span 8, spring 14 is compressed, seal ring 13 and valve body 6 air outlets are separated, connecting base 4 props up to the direction of steam outlet pipe connecting tube 1 under the promotion of valve body 6, spring 9 is compressed, and the liquid gas in the hydraulic pressure gas tank is through sebific duct, suction tude link press span 8, valve 6 air outlets, connecting base 4, vent 16, steam outlet pipe link press span 1, sebific duct is to stove and accessory.When upper sleeve cover 2 and lower sleeve cover 15 are separated, valve body 6 is under the drive of suction tude link press span 8, the groove that makes locking ball 12 break away from valve body 6 tops, return to original position, connecting base 4 and depression bar 5 are respectively under the effect of spring 9,14, all return to original position, seal ring 13 closely contacts with the valve body air outlet hole, cuts off the path of liquid gas.
