Description

A kind of valve

The utility model relates to the control gear of transfer conduit, is meant a kind of spherical valve door lock that utilizes key pilot line break-make especially, applicable to the control of the transfer conduit of tap water, heating installation, combustion gas.

Be the direction and the flow of controlling liquid, gas transmission, on various liquid, gas transmission pipeline, all control valve will be set.Prevailing as tap water, fuel gas pipeline is provided with different switches, valve, and the control valve in the general user family mostly adopts hand to turn switch valve, and this switch valve is manipulated more simple and convenient.Particularly tap water, combustion gas are charged according to use amount at present, if the situation that the individual user is late for paying dues according to quantity takes place, the supplier can't carry out effective restraint, promptly can cause unnecessary dispute.

The purpose of this utility model provides a kind of valve that utilizes key pilot line break-make, is beneficial to public water, the gas supplier effectively controls, restricts the user.

The technical solution of the utility model is: one with in be equipped with in the valve body that the pipe joint of spherical valve is connected as a single entity valve be housed, this valve mainly is made up of lock body, lock core, Returnning spring, overcoat and little stifled institute.Coat suit lock body and is fixed in the valve body, and this overcoat is a cylindrical shape lid, and its central authorities are provided with lockhole, described lock body is a cylindrical body, there are a through hole and stepped recesses in the centre, and lock core passes through hole, and its top and spherical valve are fixed, the flange of the other end is installed in the groove of lock body, the projection that two symmetries are arranged on the flange is equipped with Returnning spring in the blind hole on this lock core axis, and this Returnning spring the other end is installed in little the blocking up, under action of reset spring, little blocking up can block be lived lockhole.

Be to strengthen the protective of valve, the periphery of overcoat lockhole is provided with several width, the depth, breach that angle is different, has only the special key that matches can opening and closing like this.

Accurately locate for ease of switch, be provided with positioning dowel in the groove of lock body, this positioning dowel cooperates with projection on the lock core flange, opens, closes the angle of rotational fixation, accurately location with indication.

Advantage of the present utility model is: 1, practical, this valve is installed on input user's the pipeline, as owe to pay dues and use situation, the supplier can close this family pipeline, do not use and do not influence other users, this user does not have private key, open valve door lock voluntarily, thus reach the purpose of effective restraint; 2, reliability height, all kinds of lock mutual-opening rates of Xiao Shouing are very high in the market, and reliability is relatively poor, and its structure of this valve is different from other all kinds of locks, can effectively avoid opening mutually situation and take place; 3, applied widely, tap water, combustion gas, heating conveying tube Lu Shangjun can install; 4, simple in structure, easy processing, fabricating cost is cheap, and is easy to operate, helps applying.

Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.

Fig. 1. the utility model structural representation

Among the figure: 1. little stifled; 2. lock core; 3. Returnning spring; 4 lock bodies; 5 overcoats; 6 valve bodies; 7.O type packing ring, 8. jackscrew, 9. pin; 10. spherical valve.

As shown in Figure 1, present embodiment adopts the transformation of the way of universal standard ball valve to form, and pipe joint and valve body 6 are cast as one, and are provided with spherical valve 10 in the pipe joint.Valve is mainly by little by stifled 1, lock core 2, Returnning spring 3, lock body 4, overcoat 5 is formed, overcoat 5 suits lock body 4 and are fixed in the valve body 6, periphery is fixing with three jackscrews 8, overcoat 5 central authorities are provided with the lockhole of given shape, in the through hole in the middle of the lock body 4 lock core 2 is housed, these lock core 2 tops and spherical valve 10 are fixing, the two can rotate synchronously, its flange of the other end of lock core 2 is installed in the groove of lock body 4, and the projection that two symmetries are arranged on the flange, lock core 2 is along installing Returnning spring 3 in the blind hole of axis, this spring the other end be loaded on little stifled in, but little stifled 1 under the effect of spring 3 block live lockhole.

Be provided with positioning dowel 9 in the groove of lock body 4, the projection on the flange of this positioning dowel and lock core 2 cooperates, and lock core 2 can only be turned an angle, with indicator cock position and accurate location.

Lock core 2 is provided with RUBBER O type packing ring with valve body 6 connecting parts, to prevent liquid, gas leak.

The using process of this valve is that supporting key is inserted in the lockhole, little stifled 1 is pushed in lock core 2 blind holes, compression reseting spring 3, this moment, key was stirred two symmetrical projections on the lock core flange, can drive lock core 2 and spherical valve 10 rotations, turn to several angle (as 90 °), dowel pin 9 props up mutually with projection on the flange, makes pipeline be in accurate unlatching or closed condition, and this moment, key can eject automatically.Present embodiment is when embodiment, and lock core, lock body, overcoat all adopt brass material to make, and requires valve size unanimity when installing and using on 4 minutes, 6 minutes, 1 cun pipeline, so that produce, install, use.
