Embodiment
Facilitate the dual-active of adjust flux to tie safety check embodiment referring to figs. 1 through Fig. 3 to the utility model to be described further.
A kind of dual-active knot safety check facilitating adjust flux, comprise valve body 1, two of described valve body 1 is equipped with the loose joint portion 11 be connected with pipeline, the flap 12 for non-return is provided with in described valve body 1, described valve body 1 is equipped with adjustable lever 3, described adjustable lever 3 is positioned at one end of valve body 1 and described flap 12 is conflicted, described valve body 1 is provided with the fixed tube 2 running through valve body 1, described adjustable lever 3 is provided with circumferential fixture block 31, the circular groove 21 of several and described fixture block 31 clamping on described fixed tube 2 inwall, described fixed tube 2 inwall is also provided with for described fixture block 31 along fixed tube 2 chute 22 in axial sliding, the groove depth of described circular groove 21 is greater than the groove depth of described chute 22, one end that described fixed tube 2 is positioned at valve body 1 outside is provided with sealing cover 23, described adjustable lever 3 runs through described sealing cover 23.
Preferably, described loose joint portion 11 is for connecting tube, and both sides all can be connected with pipeline for the present embodiment.
Preferably, described fixed tube 2 and adjustable lever 3 are skewed the present embodiment, and adjustable lever 3 and flap 12 are conflicted, the setting of flap 12 be just for non-return, can only a direction flowing for liquid, prevent liquid backflow.
By adopting technique scheme, during the flow that people need adjustment safety check to limit, first rotary regulating lever 3, fixture block 31 on adjustable lever 3 is docked with chute 22, adjustable lever 3 is moved axially again along fixed tube 2, the position of such adjustable lever 3 is moved, and the position of conflicting from flap 12 is also different thus limit the stretching degree of flap 12, completes the effect of current limliting; When being by the time adjusted to correct position, rotary regulating lever 3, fixture block 31 sticks into another circular groove 21 thus completes spacing.
One end that described adjustable lever 3 is positioned at fixed tube 2 outside is provided with circular swing handle 33, and described swing handle 33 is provided with latch 34, and described sealing cover 23 is provided with several jacks 25 coordinated with latch 34.
Preferably, described jack 25 circumferentially for the present embodiment.
By adopting technique scheme, people need after secured adjusted bar 3, and latch 34 is being inserted jack 25, like this in usual situation, adjustable lever 3 will be fixed, and can not rotate because of the hydraulic shock of the inside, affect the working condition of valve, ensure the stable of valve.
The seal ring 24 of O type is provided with between described sealing cover 23 and described adjustable lever 3.
Preferably, be provided with the groove holding seal ring 24 in described sealing cover 23, seal ring 24 is embedded in inside groove the present embodiment, conflicts with adjustable lever 3.
By adopting technique scheme, owing to there being being arranged on of seal ring 24, although adjustable lever 3 can rotate and move up and down, good sealing can also be kept, preventing valve from occurring the phenomenon of leaking.
