Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention being further described, it should be noted that: the present embodiment is descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of can tuning formula safety check, comprise valve body 1, rubber valve seat 14, valve gap 6, valve rod 3, clack box 2 and hollow ball valve 12, as shown in Figure 1, valve body middle part is shaped with valve chamber, valve body left end lateral direction penetrating is shaped with the medium runner being communicated with valve chamber, and the coaxial setting-in of medium runner inner end is fixed with a rubber valve seat; Valve body right-hand member is coaxially fixed with a valve gap by bolt co-axial seal, is shaped with the medium runner with the coaxial perforation of medium runner of valve body on valve gap, and the coaxial setting-in of this valve gap medium runner inner end is fixed with another rubber valve seat.The medium runner port of left end is A end, and the medium runner port of right-hand member is B end.
In order to guarantee the installation sealing of valve body and valve gap, described valve body contacts end face inner side and is coaxially pressed with mouth sealing ring 10 in valve gap.
The valve body upper lateral of medium runner top is provided with a valve rod, and this valve rod left end is coaxially installed with an axle sleeve 15, and this axle sleeve is inlaid in installing blind made in valve body, and valve rod right-hand member stretches out valve gap, and Joystick or electronic, pneumatic regulation unit are installed; In order to guarantee sealing, at the contact position of valve rod and valve gap, multiple tracks O RunddichtringO is installed.
Valve rod middle part in valve chamber inside is shaped with outside thread, and by this outside thread, on valve rod, lead to regulate a clack box is installed, valve body wall is shaped with many horizontal guiding ribs 11, these many guiding ribs all coordinate with the made guiding groove slip setting-in of the outer wall of clack box, and this clack box drives the direction along guiding rib in the chamber interior of valve body to move axially by valve rod; And at guiding rib, near valve body bottom position, be equipped with the positioning step (in figure not label) of clack box.
Clack box inside is shaped with the interior cavity of clack box of transverse uniaxial, the transverse ends of this clack box cavity is all shaped with limited step 4, the coaxial movable hollow ball valve of installing in clack box cavity between the limited step at these two ends, valve ball can only move freely in clack box chamber, valve ball can be given prominence to clack box cavity but be subject to the restriction of limited step can not depart from clack box chamber, and the protruding terminus of hollow ball valve coordinates with valve seat inner seal.
Limited step is shaped with the curved end coordinating with hollow ball valve, and when the push-tight of pressure medium hollow ball valve is during to end, limited step and hollow ball valve are sealed and matched.
Described valve rod right-hand member stretches out valve body and by coaxial rotation, one indicating sleeve 8 is installed, and this indicating sleeve radially side is shaped with pointer 7; The outer coaxial sleeve of valve gap is equipped with a protecting jacket 9, and this protecting jacket upper end is shaped with an indication window 16, and described pointer is stretched out by the indication fenestra of protecting jacket, and moves axially with the movement of valve gap, and pointer movement direction is consistent with the movement direction of clack box.
On the valve rod of described valve gap inner side, be coaxially shaped with the anti-step 5 that flies out, this anti-step that flies out can be done the positioning step of clack box simultaneously.
Working principle of the present invention is:
When medium is held and entered by A; by external force rotation valve rod, drive clack box to move; the positioning step that clack box is moved to A end and is provided with clack box by guiding rib near valve body bottom positions, and pointer also can move to the position of the close A end of visual window on valve rod protecting jacket thereupon.Under the active force of medium, the accent that valve ball moves near B end in clack box chamber goes out, and medium can be flowed in valve body chamber by space between valve body and clack box 13, thereby flows out by outlet end; After A end medium is cut off, B end medium will reflux, effect lower valve ball at reflux medium moves to A end in clack box chamber, thereby and carry out with A end valve seat insert the effect that gluing, sealing reaches prevention medium back flow, when gluing, sealing, the step of clack box chamber end can not contact with valve ball, cause valve ball under nature, to be subject to medium thrust and seal, thereby reached non-return effect.
When the pipeline medium flow direction changes, medium is held and is entered by B; by external force rotation valve rod, drive clack box to move; clack box is moved to B end and positioned by the step on valve rod; pointer also can move to the position of the close B end of visual window on valve rod protecting jacket thereupon, thereby has reached non-return effect.
