Description
Technical field
The utility model relates to gate valve technical field, particularly relates to a kind of ball valve.
Background technique
, because of long-time (especially night) unmanned, often there is valve opening stolen, bring very large loss to oil recovery factory in the gate valve control point of a large amount of well mouth of oil well in field, current oil field, the oil outlet of oil storage tank and petroleum pipeline.In order to prevent stolen, each production crew and oil transportation station and valve manufacture factory all devise theft-proof gate valve.The main anti-theft product in current scene has following a few class: one is pin with the handle of chain and lock handle gate valve, and this method is too simple, and chain is very easily destroyed by lawless person, can not play good anti-theft function; Two is adopt cipher lock, but password is difficult to remember, and is just difficult to control once spread; Three is production wellhead or gate valve cover with protective housing, this method is on-the-spot more common at present and relatively effective mode, although can stolen be prevented, but make troubles to the maintaining of oil well and gate valve and operation, when needs maintenance well head or opening and closing gate valve, must employ crane or electrogas welding is hung away guard shield or cuts open, cost is higher, go wrong once well head or oil-gas pipeline simultaneously and be just difficult to process in time, there is accident potential; Four is adopt common lock to add special spanner or be used alone special spanner opening and closing gate valve, but a set of guard shield matched of welding first will be processed on the body of gate valve, common lock is easy to destroyed or breaks, special spanner generally adopts off-gauge tripartite, five sides and abnormally-structured etc., and be easy to be copied, therefore anti-theft effect is undesirable, and cost is also high.
Anti-theft product in view of the above, a kind of structural type must be developed unusual, for a kind of theft-proof gate valve at the oil outlet of production wellhead, oil storage tank and the gate valve control point of petroleum pipeline, this theft-proof gate valve can play antitheft and ensure that the devices such as production wellhead are intact, the effect of durable, also can reduce the probability of stolen and the generation of accident simultaneously.
Model utility content
The purpose of this utility model is to propose a kind of ball valve, has anti-theft feature, can reduce the probability of stolen and the generation of accident and ensure that the devices such as production wellhead are intact, durable.
For reaching this object, the utility model by the following technical solutions:
A kind of ball valve; comprise valve body; the valve rod that described valve inner is provided with valve ball and is connected with valve ball, sheathed protection block on described valve rod, described protection block is connected with electronic lock; when electronic lock receives unlocking signal; described electronic lock is the unblock of protection block, and described protection block can depart from described valve rod, when electronic lock does not receive unlocking signal; when electronic lock is in locking state, described protection block cannot depart from described valve rod.
Further technological scheme, described protection block is for establishing reeded block, and described valve stem end stretches in described groove, and the sidewall of described protection block is offered porose, is provided with lock core in described electronic lock, and described lock core inserts locking protection block in described hole.
Further technological scheme, the end of described valve rod is hexagonal column, and the shape of cross section of described groove is identical with the shape of cross section of described valve stem end, and described groove and described valve stem end are Spielpassung.
Further technological scheme, is provided with spring between described valve stem end and described bottom portion of groove, and when described protection block is locked, described spring is in compressive state.
Further technological scheme, described hole is through hole, is connected with described groove.
Further technological scheme, described protection block skin is provided with protective housing.
The beneficial effects of the utility model:
A kind of ball valve that the utility model proposes; its valve stem end is arranged with protection block; protection block is locked by electronic lock, and electronic lock needs to accept the signal that central control chamber sends, and electronic lock could be protect block unblock; afterwards could Non-follow control valve rod; carry out the operations such as sampling detection, this kind of ball valve has anti-theft feature, and Security is high; can not be cracked, the probability of stolen and the generation of accident can be reduced.
Accompanying drawing explanation
Fig. 1 is the structural representation of the ball valve that the utility model embodiment provides;
Fig. 2 is the structural representation of the protection block that the utility model embodiment provides.
Wherein, 1, valve body; 2, valve ball; 3, valve rod; 4, block is protected; 5, electronic lock; 6, groove; 7, hole; 8, lock core; 9, spring; 10, protective housing; 11, sampling connection.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the ball valve that the utility model embodiment provides.A kind of ball valve; comprise valve body 1; the valve rod 3 that valve body 1 inside is provided with valve ball 2 and is connected with valve ball 2, sheathed protection block 4 on valve rod 3, protection block 4 is connected with electronic lock 5; when electronic lock 5 receives unlocking signal; electronic lock 5 unlocks for protection block 4, protects block 4 can depart from valve rod 3, when electronic lock 5 does not receive unlocking signal; when electronic lock 5 is in locking state, protection block 4 cannot depart from valve rod 3.
In this embodiment; as shown in Figure 2; protection block 4 is for being provided with the block of groove 6, and reliability and durability, valve rod 3 end stretches in groove 6; wherein valve rod 3 end is hexagonal column; correspondingly, the shape of cross section of groove 6 is identical with the shape of cross section of valve rod 3 end, and groove 6 and valve rod 3 end are Spielpassung; groove 6 and valve rod 3 end are coordinated compact, and protection block 4 can not be oversize and cause protection block 4 unstable due to groove 6.The sidewall of protection block 4 offers porose 7, and particularly, hole 7 is through hole, is connected with groove 6, as shown in Figure 1, is provided with lock core 8 in electronic lock 5, locking protection block 4 in lock core 8 patchhole 7.
Be provided with spring 9 between bottom valve rod 3 end and groove 6, when protecting block 4 to be locked, spring 9 is in compressive state, and after protection block 4 is unlocked, due to the effect of spring 9, protection block 4 is upspring, and easily takes protection block 4 away, convenient to operation.
