Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to a kind of stop valve of Double-clack.
Background technique
Common stop valve on market is when opening and closing valve, the object of switch need be reached by the mode turning handwheel, but when needs frequently Push And Release time, turn handwheel frequently very inconvenient, and opening and closing time is longer, keying moment is large, keying is comparatively required great effort.Simultaneously, the stop valve in market has certain flow direction property, same employing from top to bottom, utilize the flowing of fluid to make flap be clamped in spool mouth, and the passage that water inlet and valve rod are installed communicates, therefore stop valve is equipped with filler, anti-fluid spills in the gap between valve rod and valve body, there is the problem of sealing deficiency in part stop valve, cause fluid to spill in the gap between valve rod and valve body, sealing reliability is not strong after a period of use.
At present, application number be 201120457293.8 Chinese patent disclose a kind of stop valve, it comprises valve body, valve seat, flap, valve rod, valve gap and handwheel, valve seat is arranged in valve body, supports flap, and valve gap is arranged on above valve body, described valve rod is arranged in valve gap and valve body, lower end connects flap, and flap is the direct effect part that described stop valve regulates pipeline medium flow velocity, and handwheel is installed on the top of valve rod.Although this stop valve can make people by rotating handwheel to regulate the work of pipeline medium flow velocity, when rate-of flow is too high cause hydraulic pressure to strengthen time, stop valve is lower in off position can automatic unlatching, causes the sealability of stop valve bad.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the stop valve providing a kind of good seal performance.
For achieving the above object, the utility model provides following technological scheme: a kind of stop valve of Double-clack, comprise valve body, valve rod, handwheel, valve gap, valve seat and flap, described valve body comprises inlet passage and outlet passage, it is characterized in that: described flap comprises the first flap, the second flap, described first flap is fixedly connected with one end of valve rod and is arranged on the below of valve seat, described second flap to be threaded on valve rod and to be in the top of valve seat, described valve body is provided with the position-limit mechanism for limiting the second flap axial rotation.
By adopting technique scheme, first flap is fixedly connected with one end of valve rod and is arranged on the below of valve seat, can effectively prevent from rate-of flow too high and cause pressure medium to increase pushing the first flap open, valve rod has been threaded the second flap, and be in the top of valve seat, can coordinate with threaded stem thus utilize the second flap to move up or down in the process that stop valve opens and closes and coordinate with the first flap, the first flap is made to seal up below valve seat, second flap seals up above valve seat, thus reach sealing outlet passage and inlet passage by the two sides of valve seat, ensure sealability, the setting of position-limit mechanism can make the second flap stable operation.
The utility model is set to further: described valve rod is provided with thread section, and described second flap is provided with tapped hole, described thread section and tapped hole screw-thread fit, and the pitch of described thread section is greater than the pitch that valve rod coordinates with valve body.
By adopting technique scheme, the thread section that valve rod is arranged is threaded with the tapped hole on the second flap, drives the second flap to move up and down, thus complete the keying above the second flap and valve seat by rotation valve rod by thread section.
The utility model is set to further: described position-limit mechanism is fixing rod, and described fixing rod to be fixedly connected in valve body and to be arranged in parallel with valve rod.
By adopt technique scheme, fixing rod is fixedly connected with valve body in and be arranged in parallel with valve rod, when being to coordinate with slide mechanism, ensure stable operation in the process that slide mechanism slides up and down.
The utility model is set to further: described second flap is provided with annulus button, and described annulus button is fixedly connected with the second flap, and described annulus button is slidably set on fixing rod.
By adopting technique scheme, annulus retaining ring is located on fixing rod, and can slide up and down, thus drive the second flap the second flap can not be caused to rotate together with valve rod by the rotation of annulus button in the process of valve rod rotation, and then valve rod is made to drive the second flap to move up and down by thread section.
The utility model is set to further: described fixing rod is set to two, and what described annulus button was corresponding is set to two, and described annulus button is all fixedly connected with the second flap, and is set in respectively on two fixing rods.
By adopting technique scheme, fixing rod and annulus button being all set to two, the second flap can be made so more stable in the process of work.

Embodiment
Be described further with reference to Fig. 1, Fig. 2 stop valve embodiment to the utility model Double-clack.
A kind of stop valve of Double-clack, comprise valve body 1, valve rod 2, handwheel 3, valve gap 4, valve seat 5 and flap, described valve body 1 comprises inlet passage 11 and outlet passage 12, described flap comprises the first flap 6, second flap 61, described first flap 6 is fixedly connected with one end of valve rod 2 and is arranged on the below of valve seat 5, described second flap 61 to be threaded on valve rod 2 and to be in the top of valve seat 5, described valve body 1 is provided with the position-limit mechanism for limiting the second flap 61 axial rotation.
Described valve rod 2 is provided with thread section 21, described second flap 61 is provided with tapped hole 611, described thread section 21 and tapped hole 611 screw-thread fit, the pitch of described thread section 21 is greater than the pitch that valve rod 2 coordinates with valve body 1.
Described position-limit mechanism is fixing rod 7, and described fixing rod 7 to be fixedly connected in valve body 1 and to be arranged in parallel with valve rod 2.
