Description

A kind of valve key

Technical field

This utility model relates to valve auxiliary switch technical field, furthermore relates to one Plant valve key.

Background technology

For a fairly large number of valvelet, open and close process is the most loaded down with trivial details, wastes time and energy, Such as power plant dish valve, second phase desulfuration absorbing tower liquidometer rinse at manually operated door, low-level (stack-gas) economizer Manually operated door.These valvelets usually rely on staff or spanner switchs, and need to apply Active force relatively big, cause switching process numerous, be also easy to during operation scratch hands, inefficiency.

Therefore, for a person skilled in the art, a kind of time saving and energy saving switch how is designed The instrument of valve, improves operating efficiency, is to be presently required to solve the technical problem that.

Utility model content

For solving above-mentioned technical problem, this utility model provides a kind of valve key, including before Latch, rear latch and turning handle；Described front latch and described rear latch are parallel to each other and all with described Turning handle is vertically fixed；Described front latch is fixed on the end of described turning handle, consolidating of described rear latch Fixed place mates with corresponding valve with the distance of described front latch bearing, described front latch and institute State rear latch can vertically be stuck on valve.

Alternatively, described turning handle being also fixedly installed handle, described front latch and described handle divide It is not positioned at the two ends that described turning handle is relative；Described front latch and described handle be parallel to each other and towards On the contrary.

Alternatively, described handle also rotates suit turning handle.

Alternatively, described rear latch can slide on described turning handle, and corresponding position with Described turning handle is fixed.

Alternatively, described rear latch is sleeved on described turning handle by sliding sleeve, described slip Through hole is offered in side relative with described rear latch on sleeve, and through-hole wall arranges female thread, logical Cross bolt to rotate to tighten with described turning handle and coordinate.

Alternatively, the cross section of described turning handle is rectangle or polygon, inside described sliding sleeve Through hole identical with the shape of cross section of described turning handle.

This utility model provides a kind of valve key, including front latch, rear latch and turning handle. Front latch is vertical with turning handle to be fixed, and rear latch is vertical with turning handle to be fixed, and front and back latch is parallel to each other. Front latch and turning handle bearing and rear distance between latch and turning handle bearing and valve phase Joining, front latch and rear latch can vertically be stuck on valve.Front latch is fixed on the one of turning handle End tip position, rear latch is spaced a distance fixing with front latch, and both towards phase With.

In use, front latch and rear latch are vertically stuck on valve, by rotating turning handle The other end valve can be turned.When twisting, power arm is more than resistance arm, can be less Twist valve under active force, reach labour-saving effect, can realize rapidly tightening and loosening, Improve the efficiency of loading and unloading.

Detailed description of the invention

Core of the present utility model is to provide a kind of valve key, reduces work when valve turns Firmly, improve the efficiency of loading and unloading.

In order to make those skilled in the art be more fully understood that the technical solution of the utility model, under The valve key of the application will be carried out specifically by face in conjunction with accompanying drawing and specific embodiment Bright.

As it is shown in figure 1, the Facad structure signal of a kind of valve key be given for this utility model Figure.Specifically including front latch 1, rear latch 2 and turning handle 3, front latch 1 and turning handle 3 are vertically solid Fixed, rear latch 2 and turning handle 3 are vertically fixed, and front latch 1 and rear latch 2 are parallel to each other. Front latch 1 is fixed on the end, one end of turning handle 3, the bearing of front latch 1 and turning handle 3 and It is spaced a distance between rear latch 2 and the bearing of turning handle 3, this distance and valve phase Coupling, front latch 1 and rear latch 2 can vertically be stuck on valve, namely front latch 1 exists The plate face of valve it is perpendicular to when coordinating clamping with valve.

Use the valve key that the application provides, when twisting valve, owing to power arm is more than resistance The arm of force, therefore the less active force of operator's applying just can produce the biggest moment, can be fast Speed makes valve rotate effortlessly, improves the efficiency twisting valve.And the knot of whole device Structure is simple, it is simple to carry.

Further on this basis, as in figure 2 it is shown, represent another kind of concrete structural representation. During in order to make operator twist convenient, turning handle 3 is also fixedly installed handle 4, handle 4 3 two relative ends of turning handle it are separately fixed at front latch 1, and handle 4 and front card Tooth 1 is parallel to each other, simply both towards difference, front latch 1 and rear latch 2 are being clamped on Time on valve, operator can apply active force by pulling handle 4 to turning handle 3, makes operation Process is more convenient.

Furthermore it is also possible to be set with turning handle 41, turning handle 41 and handle on handle 4 4 can relatively rotate, and operator holds turning handle 41, between turning handle 41 and hands Do not relatively rotate, occur relatively rotating, it is to avoid right between turning handle 41 and handle 4 Staff causes friction, plays certain protective effect, also improves the comfortableness of operation.

In order to make valve key can be useful on different valves, rear latch 2 and turning handle 3 phase Arranging sliding, rear latch 2 can be along the axial sliding movement of turning handle 3.Rear latch 2 and turning handle 3 Can fix at corresponding ad-hoc location, both can bear torsion force.

Specifically, rear latch 2 is fixed on sleeve 21, is sleeved on turning handle 3 by sleeve 21 On, through hole is offered in side relative with latch 2 on sliding sleeve 21, and through-hole wall is arranged Female thread, can coordinate with bolt, rotates to tighten with turning handle 3 by bolt and coordinates, bolt general Sliding sleeve 21 is positioned on turning handle 3.In addition to said structure, turning handle 3 arranges chute, Latch 2 slide in chute and can relatively-stationary mode also possible.

Further, the shape of cross section of turning handle 3 is rectangle or polygon, sliding sleeve 21 Internal through hole is identical with the shape of cross section of turning handle 3, and size can not cooperate between the two Now relatively rotate, certainly, oval also possible.In addition, if turning handle 3 is cylinder Shape, arranges a projection along axis on turning handle 3, and sliding sleeve 21 is offered corresponding groove, Both cooperate prevent from relatively rotating also possible.

In sum, the valve key using this utility model to provide, use less active force Just valve can be applied the biggest moment of torsion, can valve is tightened or loosens with fast power-saving, Reach time saving and energy saving purpose.Latch 2 and the relative distance of front latch 1, Ke Yishi after regulation For different valves.

Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of Or use this utility model.To the multiple amendment of these embodiments professional technique people to this area Will be apparent from for Yuan, generic principles defined herein, can be without departing from this In the case of the spirit or scope of utility model, realize in other embodiments.Therefore, this reality By the novel the embodiments shown herein that is not intended to be limited to, and it is to fit to and institute herein Disclosed principle and the consistent the widest scope of features of novelty.
