Abstract
The utility model relates to a simple locking valve, which comprises a valve body, a sphere valve core and a handle, wherein the handle controls the closing of the sphere valve core and is connected onto a valve rod, and a stop block and a stop edge which are mutually matched and are used for limiting the rotation angle of the handle are arranged in corresponding positions of the valve body and the bottom end of the handle. As the improvement of the simple locking valve, at least one stop groove matched with the stop block is formed on the stop edge. When being used, the simple locking device can also be used as an ordinary ball valve, a sink hole is formed in a position on the handle connected with the valve rod, and a connecting head is connected with the valve rod in the sink hole and is dismounted and mounted through an installing handle. When the simple locking valve needs to be used as a locking valve, the ball valve handle is rotated to maintain the open or closed state, the handle is dismounted through the installing handle, the handle is rotated, the stop groove formed on the stop edge is clamped with the stop block to realize mutual matching, the connecting head is tightly screwed through the installing handle, the ball valve handle is locked, and the simple locking valve can be used as the locking valve and can maintain the open or closed state. The situation that the open and closed states of the valve core in unexpected operation are changed is prevented.
Description
Technical field
The utility model relates to a kind of locking valve, especially can doublely do the locking valve of ordinary ball valve.
Background technique
The locking valve that is widely used in hot and cold water, hot duct has the unique function that can close and can not open arbitrarily, and opening needs specific key.But, frequently open, close unlatching as one group of needs in a family of water system and seem very inconvenient for domestic consumer.Present locking valve mainly is by magnetic principles control, and this locking valve function singleness, complex structure, cost are high relatively.
Summary of the invention
The utility model provides a kind of simple in structure for solving the problem that existing locking valve in use exists, and is easily manufactured, can doublely do the simple and easy locking valve of ordinary ball valve.
The technological scheme that the utility model solves existing issue is: a kind of simple and easy locking valve, comprise that valve body, spheroid spool, control spheroid spool closure are connected in the handle on the valve rod, described valve body and corresponding position, handle bottom are provided with stop block and the retaining edge that cooperatively interacts, limits the handle angle of swing, as improvement of the present utility model, described retaining edge be provided with the locking groove that matches with stop block at least one.
As further improvement of the utility model, the joint of described handle and valve rod is provided with counterbore, is provided with the connecting head that connects handle and valve rod in the described counterbore.
As further improvement of the utility model, described counterbore is provided with protecting cover, and protecting cover prevents that dust, water, air from contacting with connecting head, the protection joint.
As further improvement of the utility model, described locking groove is provided with two, and described two locking groove starting points align with the starting point of the opposite position that keeps off edge respectively.
As further improvement of the utility model, described protecting cover is bolted on the counterbore.
As further improvement of the utility model, described connecting head is bolted on the valve rod.
As further improvement of the utility model, described connecting head is provided with mounting groove.
As further improvement of the utility model, comprise that also one matches with the connecting head mounting groove mounting handle of connecting head is installed.
As further improvement of the utility model, described mounting handle is provided with swing handle.
As further improvement of the utility model, the mounting groove on the described connecting head is arranged on the circumference, and described mounting handle is provided with the internal tooth that matches with mounting groove.
The utility model can be held concurrently when its beneficial effect is to use compared with prior art as ordinary ball valve, establishes counterbore with the joint of valve rod on handle, and connecting head is connected with valve rod in counterbore, and by the mounting handle dismounting.In the time of need doing locking valve, the rotary ball valve handle stays open or closing state, by the mounting handle handle of dismantling, handle is rotated, the locking groove that keeps off on the edge is blocked with stop block match, connecting head is tightened, pin the ball valve handle with mounting handle, just can be used as locking valve, it is stayed open or closing state.Prevent accidental operation, change the open and-shut mode of spool.

Embodiment
Referring to Fig. 1-3, the implementation case comprises that valve body 1, spheroid spool 2, control spheroid spool 2 closures are connected in the handle 4 on the valve rod 3, valve body 1 is provided with stop block 5 and the retaining edge 6 that cooperatively interacts, limits the handle angle of swing with corresponding position, handle 4 bottom, and retaining edge 6 is provided with the locking groove 61 that matches with stop block 5.
As preferably, handle 4 is provided with counterbore 41 with the joint of valve rod 3, and counterbore 41 is bolted with protecting cover 43, is provided with the connecting head 42 that connects handle 4 and valve rod 3 in the counterbore 41, and connecting head 42 is provided with mounting groove.Retaining edge 6 restriction handle angle of swing are 90 °, and locking groove 61 is provided with two, and two locking groove 61 starting points align with the starting point of the opposite position that keeps off edge 6 respectively.
Comprise that also one matches with connecting head 42 mounting grooves 44 mounting handle 7 of connecting head 42 is installed, use for convenience that mounting handle 7 is provided with swing handle 71, the mounting groove 44 on the connecting head 42 is arranged on the circumference, and mounting handle 7 is provided with the internal tooth 72 that matches with mounting groove 44.
This product is usually double do common, rotatory handling 4, spheroid spool 2 is stayed open or closed condition, cooperate with connecting head by mounting handle 7, take handle 4 apart, with any locking groove 61 on the handle 4, match with the stop block 5 on the valve body 1, by mounting handle 7 and connecting head 42, lock handle 4, handle 4 will be held locking.Referring to Fig. 4-5, spheroid spool 2 keeps normally open.Referring to Fig. 6-7, spheroid spool 2 keeps normally off.
