Abstract
The utility model relates to a disposable pipeline lock, which is composed of a valve-shaped main body, a handle, a rotary shaft, and a water baffle, wherein, the middle part of the rotary shaft is provided with an annular groove, the bearing range of which is from 0.001 to 10 MPa, and besides, the lock also comprises a steel wire fork lock which is used for locking the handle by connecting through holes arranged on yuanbao-shaped closure nuts on the top of the valve-shaped main body and the rotary shaft with the handle. When a transfer line needs to be locked, after a special person opens the steel wire fork lock, the rotary shaft is operated by a hand causing the annular groove on the rotary shaft to break, and the locking state can be achieved after the transfer line is closed in a disposable way. The lock is mainly used for heat supply, water supply, and disposable locking of liquefied gas and various industrial pipelines.
Description
The utility model relates to the tube equipment of the pipeline of different tube diameters being carried out control, is a kind of disposable tubing lock that is applied to pipelines such as heat supply, tap water, liquid gas are carried out switch control specifically.
At present, the device main structure that is used for pipeline is carried out switch control is to be made of valve shape main body, handle, running shaft, manger board, upper press cover, fixed cover, seals and other component.The pipe switch device can carry out the control of flow size and switch at any time to conveyance conduit, and do not possess pipeline is not carried out by lock function after disposable the closing of the personnel that the manage direct control of managing department.
The purpose of this utility model provides a kind of by managing personnel operation, close the locking pipeline after, disposable tubing that other staff can't open lock.
The purpose of this utility model is achieved in that by four parts such as valve shape main body, running shaft, handle, manger boards to be formed, and wherein the running shaft middle part is provided with an annular groove, and force-applied scope is the 0.001-10 MPa.Use artificial rotatable handle, driven rotary axle rotation during rotation, screw thread on the running shaft drives manger board and moves up and down in the spacing seal groove of body interior, when the top of manger board at the spacing seal groove of valve shape body interior is open mode, during to below is closed condition, when exerting oneself rotatable handle once more, the annular groove on the running shaft is disconnected, thereby finish the lock state after closing.This lock also comprises a steel wire fork lock in addition, is connected to come with handle by the perforation on the precious closure nut of circle at valve shape main body and running shaft top handle is locked.In addition, the different parts on this Lock valve shape main body also can have seal arrangement, as seal ring, upper press cover etc.
Owing to take such scheme, can behind closedown of pipeline, carry out disposable locking simultaneously, only running shaft is set the part annular groove, thereby finish lock state, so this lock construction is fairly simple.But,, be that other personnel can't open if there is not special part because of pipe interior has certain pressure, gas and heat.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model plan view.
Fig. 2 is the utility model sectional arrangement drawing.
Among the figure, 1, plain cushion; 2, handle; 3, running shaft; 4, upper press cover; 5, copper packing; 6, seal ring; 7, fixed cover; 8, pipeline inlet; 9, manger board; 10, valve shape main body; 11, spacing seal groove; 12, the fork of the steel wire on valve shape main body lock perforation; 13, justify precious closure nut; 14, there is the perforation of steel wire fork lock at the precious closure nut of circle middle part; 15, annular groove; 16, nut; 17, steel wire fork lock.
In embodiment illustrated in fig. 2, valve shape main body (10) central position is provided with spacing seal groove (11), places the manger board (9) that can slide up and down in groove in the groove (11), and running shaft (3) bottom is threaded with manger board (9); Running shaft (3) middle part is provided with annular groove (15), and when surpassing the 0.001-10 MPa, annular groove disconnects, thereby pipeline is locked when stressed.Valve shape main body (10) and seal ring (6) contact, link to each other with screw thread with fixed cover (7) again, upper press cover (4) and copper packing (5) contact and seal ring (6) contacts, link to each other with screw thread with fixed cover (7), the precious closure nut of circle (13) middle part is provided with steel wire perforation (14) below and links to each other with screw thread with the top of running shaft (3), also and plain cushion (1) contact, square body on handle (2) and the running shaft (3) fixedly bayonet socket links to each other, and valve shape main body (10) goes up both sides and is provided with steel wire fork lock perforation (12).As shown in Figure 2, original steel wire fork lock (17) passes the steel wire perforation (14) that the steel wire fork lock perforation (12) on valve shape main body (10) both sides passes again on the precious closure nut of circle (13) becomes the closed loop locking state.
Model utility disposable tubing lock is installed on the conveyance conduit of different tube diameters, when needs are closed locking to pipeline, after opening steel wire fork lock (17) manually rotatable handle (2) makes it reach closed condition by the personnel of managing, firmly rotatable handle (2) makes annular groove disconnection on the running shaft again, reach the disposable locking state after closing, the pipeline inlet is closed.As open pipeline and then need manage personnel and change running shaft (3) again and can restore, thereby reach disposable purpose of closing locking.
Claims (3)
1. the disposable tubing lock is made up of valve shape main body, running shaft, handle, shelves water plate four parts, it is characterized in that there is an annular groove at the running shaft middle part, and the strength scope is the 0.001-10 MPa.
2. according to the disposable tubing of claim 1 lock, it is characterized in that this lock also comprise an original steel wire fork lock (1) pass steel wire fork lock perforation (12) on (10) two of the valve shape main bodys pass again steel wire on the precious closure nut of circle (13) bore a hole (14) become the closed loop locking state.
3. lock its feature according to the disposable tubing in the claim 1,2 and on this Lock valve shape main body, seal arrangement is housed.
