Description
Technical field
The present invention relates to valve technology field, especially relate to a kind of permanent control valve.
Background technique
Valve produces along with the generation of fluid circuit, and so far, the mankind use valve to have nearly 4000 years history.Based on very long development course, it has various ways.A kind of valve wherein comprises valve body, spool and rotating handle.Wherein, this valve body is provided with inner chamber and by connection mouth water intake and the water outlet that face connects that dam; This spool is arranged in inner chamber and this spool and this connection mouth face that dams and matches, and this spool and the interlock of this rotating handle.Certainly, pass through threaded between the inner chamber of spool and valve body.Like this, turn rotating handle, spool can be rising or the decline of rotation status, realize folding (that is, spool bottom opens or closes this connection mouth face that dams) between face thereby the bottom of this spool and this connection mouth dam.Its defective is: spool and connection mouth dam face when carrying out folding, spool is rotation status, thereby not only cause need to be larger moment of torsion can the turn rotating handle, and rotating handle and the connection mouth phase mutual friction between face of damming, and then spool is easy to wear and tear and working life of having reduced valve.
Summary of the invention
The purpose of this invention is to provide a kind of permanent control valve, it has, and need not can the turn rotating handle than high pulling torque, and the less characteristics of the wearing and tearing of spool.
The technical solution adopted in the present invention is: permanent control valve, comprise valve body, spool and rotating handle, wherein, this valve body is provided with inner chamber and by connection mouth water intake and the water outlet that face connects that dam, this spool is arranged in inner chamber and this spool and this connection mouth face that dams and matches, this spool and the interlock of this rotating handle, described this inner chamber top are fixed with fixed positioning piece, and this fixed positioning piece is provided with gliding groove; This valve core inside card has mobile link spare, and this mobile link spare outside is provided with and is somebody's turn to do positioning block, the inside that gliding groove matches and is provided with internal thread; Simultaneously, this rotating handle bottom is connected with connecting screw rod, and this connecting screw rod and this internal thread match.
Be provided with spring between the bottom of described mobile link spare and this spool.
Described spool bottom is fixedly connected with Sealing by retaining screw.
Described rotating handle is connected with final controlling element.
The advantage that compared to the prior art the present invention has is: 1, need not to get final product the turn rotating handle than high pulling torque, and the wearing and tearing of spool are less.Permanent control needle of the present invention changes the dam fit system of face of spool and connection mouth.That is, rotating handle is by connecting screw rod and spool threaded, thus spool in the process of upper and lower displacement, self needn't rotate.Like this, spool and connection mouth dam between face and can not produce friction because of rotation relatively, thereby it is less to wear and tear, and produce when having avoided Spool rotating than high pulling torque, thereby rotating handle need not than high pulling torque.2, valve rod rotation internal thread without opening and closing stroke, realized that not only mechanical seal has improved the sealability of valve rod, and body size can reduce.3, dam after closing the fully sealing of face relies on the pressure of the medium such as water itself to complete to close, thereby respond well.At this moment, valve rod still can 360 ° of rotations, and common last one strength during without the final stage of conventional valves switch has alleviated the dynamics of closing, and kept the switch dynamics evenly, be fit to supporting electric actuator.4, for conventional valves, the dam fit system of face of the spool of permanent control valve of the present invention and connection mouth is comparatively good.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is that the master of embodiments of the invention looks sectional view;
Fig. 2 is the schematic perspective view of fixed positioning piece of the present invention;
Fig. 3 is the schematic perspective view of mobile link spare of the present invention;
Fig. 4 is the three-dimensional cutaway view of mobile link spare of the present invention.
In figure: 10, valve body, 11, water intake, 12, water outlet, 13, the connection mouth face that dams, 14, inner chamber; 20, spool; 30, rotating handle, 31, connecting screw rod; 40, fixed positioning piece, 41, upper gliding groove; 50, mobile link spare, 51, positioning block, 52, internal thread; 60, spring; 70, Sealing; 80, retaining screw.
Embodiment
Embodiment, see that Fig. 1 is to shown in Figure 4: permanent control valve comprises valve body 10, spool 20 and rotating handle 30.Wherein, this valve body 10 is provided with inner chamber 14 and by connection mouth water intake 11 and the water outlet 12 that face 13 connects that dam.That is, the dam folding of face 13 of connection mouth realizes perforation and the disconnection of water intake 11 and water outlet 12, thereby realizes the folding of this perseverance control valve.This spool 20 is arranged in inner chamber 14 and this spool 20 and this connection mouth face 13 that dams and matches, this spool 20 and 30 interlocks of this rotating handle.That is, this rotating handle 30 drives this spool 20 actions, thereby realizes the dam folding of face 13 of 20 pairs of connection mouths of spool.In the present invention, this inner chamber 14 tops are fixed with fixed positioning piece 40, and this fixed positioning piece 40 is provided with gliding groove 41.These spool 20 inner card have mobile link spare 50, and this mobile link spare 50 outsides are provided with and are somebody's turn to do positioning block 51, the inside that gliding groove 41 matches and are provided with internal thread 52.So-called positioning block 51 and upper gliding groove 41 match, and referring to this positioning block 51 can slide up and down in gliding groove 41 on this.Simultaneously, this rotating handle 30 bottoms are connected with connecting screw rod 31, and this connecting screw rod 31 and this internal thread 52 match.Like this, after rotating handle 30 rotations, connecting screw rod 31 rotates thereupon.At this moment, because this mobile link spare 50 can't rotate, thereby this connecting screw rod 31 is in these internal thread 52 inward turnings then drive this mobile link spare 50 and move up and down.And, after this mobile link spare 50 moves up and down, drive this spool 20 and move up and down, thereby the connection mouth face 13 that dams is realized folding.
Optimize:
Be provided with spring 60 between the bottom of this mobile link spare 50 and this spool 20.Like this, guaranteed that not only this mobile link spare 50 can be in the top of this spool 20 inside, and made 20 pairs of connection mouths of this spool dam face 13 when realizing folding, had certain buffering.
This spool 20 bottoms are fixedly connected with Sealing 70 by retaining screw 80.Like this, not only increase by 20 pairs of these connection mouths of this spool seal degree of face 13 that dams, and be convenient to change the seal 70 and protection spool 20.
Certainly, this rotating handle 30 can be connected with final controlling element (not shown on figure).Like this, the automatic control for this perseverance control valve provides condition.
In sum, this perseverance control needle changes the dam fit system of face of spool and connection mouth.That is, rotating handle is by connecting screw rod and spool threaded, thereby the spool upper and lower moves past in journey, and self needn't rotate.Like this, spool and connection mouth dam and can not produce friction because relatively rotating between face, thereby wearing and tearing are less, and rotating handle need not can realize than high pulling torque the folding of this perseverance control valve.
The above is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
