Description
Technical field
The utility model relates to a kind of valve, especially a kind of bottle valve.
Background technique
Bottle valve is widely used, and can be used in the control valve of the bottled gas such as fire suppression bottle, nitrogen bottle, and traditional bottled valve all compares effort in opening and closing, easy to be extremely trivial at the critical moment.And complex structure, sealing effect is poor, to use for a long time or is depositing the phenomenon that easily leaks air.
Summary of the invention
The purpose of this utility model is to provide a kind of compact structure, good sealing effect, opens and facilitates labour-saving bottle valve.
In order to achieve the above object, the technical solution of the utility model is: a kind of bottle valve, comprise valve body, valve gap, flap, spool, screw rod, first Returnning spring, second Returnning spring and locking nut, described valve gap is fixedly connected with one end of valve body, flap is connected with valve body slippage, and valve gap is provided with screw hole, one end of screw rod is through screw hole, and be fixedly connected with flap, one end and the flap of the first Returnning spring offset, the other end and valve body offset, slip hole is provided with in described valve body, described spool is connected with slip hole slippage, locking nut is threaded with the other end of valve body, and one end of the second Returnning spring and spool offset, the other end and locking nut offset, described valve body is also provided with intercommunicating pore, intercommunicating pore is communicated with slip hole, when flap moves down, flap can stretch in slip hole, and offset with spool, and described intercommunicating pore outer end is also provided with sealing cover.
The other end of described screw rod is also fixedly connected with handwheel, and is fixedly connected with screw rod with pad by nut.
Be provided with the first seal ring between described valve body and valve gap, between flap and valve body, be provided with the second seal ring.
After adopting said structure, locking nut of the present utility model can be connected with bottle, easy to connect.After turning screw rod, screw rod will drive flap to press down, and compresses the first Returnning spring, flap can stretch in slip hole, and offsets with spool, and is with movable valve plug to move down, slip hole is just opened by spool, and the gas in bottle just from slip hole, and can be released by intercommunicating pore.If turn screw rod in the other direction, the first Returnning spring and the second Returnning spring can compress flap and spool simultaneously, are closed by slip hole rapidly.And intercommunicating pore outer end is also provided with sealing cover, improves sealing effect.Therefore the utility model is simple and compact for structure, good sealing effect, opens convenient and strength-saving.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Figure 1, a kind of bottle valve, comprise valve body 1, valve gap 2, flap 3, spool 4, screw rod 5, first Returnning spring 6, second Returnning spring 7 and locking nut 8, described valve gap 2 is fixedly connected with one end of valve body 1, flap 3 is connected with valve body 1 slippage, and valve gap 2 is provided with screw hole 21, one end of screw rod 5 is through screw hole 21, and be fixedly connected with flap 3, one end and the flap 3 of the first Returnning spring 6 offset, the other end and valve body 1 offset, slip hole 11 is provided with in described valve body 1, described spool 4 is connected with slip hole 11 slippage, locking nut 8 is threaded with the other end of valve body 1, and one end of the second Returnning spring 7 and spool 4 offset, the other end and locking nut 8 offset, described valve body 1 is also provided with intercommunicating pore 12, intercommunicating pore is communicated with slip hole 11, when flap 3 moves down, flap 3 can stretch in slip hole 11, and offset with spool 4, and described intercommunicating pore 12 outer end is also provided with sealing cover 15.
Shown in Figure 1, in order to convenient rotary screw 5, without the need to instrument; And make screw rod 5 and handwheel 9 fixation, for convenience detach.The other end of described screw rod 5 is also fixedly connected with handwheel 9, and is fixedly connected with screw rod 5 with pad 16 by nut 14.
Shown in Figure 1, in order to improve valve gap 2 and the sealability of valve body 1 further, improve the sealability of flap 3 and valve body 1.Be provided with the first seal ring 10 between described valve body 1 and valve gap 2, between flap 3 and valve body 1, be provided with the second seal ring 13.
Shown in Figure 1, when the utility model uses, bottle valve is fixed on bottle by locking nut 8, when being rotated counterclockwise handwheel 9, handwheel 9 drives screw rod 5 to press down, and screw rod 5 drives flap 3 to move down, flap 3 stretches in slip hole 11, and is with movable valve plug 4 to move down.Spool 4 just opens slip hole 11, makes gas in bottle by slip hole 11, goes out through intercommunicating pore 12.When rotating clockwise handwheel 9, screw rod 5 drives flap 3 to move up, and the first Returnning spring 6 and the second Returnning spring 7 can compress flap 3 and spool 4 simultaneously, are closed by slip hole 11 rapidly.Therefore the utility model is simple and compact for structure, good sealing effect, opens convenient and strength-saving.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
