Description
Technical Field
The utility model relates to a combination valve spanner.
Background
The valve wrench is used for manually opening the valve so as to reduce the force when the valve is manually opened, and is widely applied to the fields of industrial devices such as chemical industry, petrifaction, petroleum, metallurgy, power generation, oil refining, machinery, oil fields and the like to be used for opening and closing the valve.
In the petrochemical industry smelting trade, still there is a large amount of valves that need the manual work to open, because the valve spanner is nonstandard instrument, each enterprise designs the valve spanner according to self needs, nevertheless because the opening size of valve spanner is fixed, and a valve spanner only can be used for opening and close the valve that the model is close, because the size difference of valve model is great, consequently need be equipped with a series of valve spanners, not only cause operating personnel's inconvenience of carrying, also caused certain management degree of difficulty. In order to reduce the number of tools, people design a multifunctional valve wrench, but the appearance of the jaw of the valve wrench is still traditional cylindrical, the jaw is mainly made of round pipes or round steel, the section of the rim of the valve hand wheel is mainly round or oval, when the valve hand wheel is rotated by the valve wrench, the contact between the valve wrench and the valve hand wheel is point contact, when a large valve is opened and closed, the valve can be rotated only by large force, the phenomenon of slipping is easy to occur, the inconvenience in operation is caused, and the time for opening and closing the valve is prolonged.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, the present invention provides a combined valve wrench, which includes a handle and a first valve wrench portion disposed at one end of the handle, the handle extends along a first axis direction, the first valve wrench portion includes a connecting rod extending along the first axis direction and a first jaw a and a first jaw B connected to two ends of the connecting rod along the first axis direction, the first jaw a and the first jaw B are disposed at an interval, the first jaw a is located at one end facing the handle, the first jaw B is located at one end of the connecting rod away from the handle; the first clamping jaw A and the first clamping jaw B extend along the direction of the second axis and have the same direction; the second axial direction is perpendicular to the first axial direction;
the first clamping jaw B comprises a cylindrical rod, and an annular groove is formed in the outer peripheral surface of the cylindrical rod;
the connecting rod is also provided with a second valve wrench part, the second valve wrench part comprises a second jaw A and a second jaw B, the second jaw A and the second jaw B extend along the second axial direction and have the same direction, and the extending direction of the second jaw A and the second jaw B is opposite to the extending direction of the first jaw A;
the distance between the first jaw a and the first jaw B is greater than the distance between the second jaw a and the second jaw B.
In the application, two valve wrench parts are arranged in the same wrench for different valve hand wheels, the first valve wrench part is used for opening and closing a larger valve, and the second valve wrench part is used for opening and closing a smaller valve. At present, a valve wrench is basically manufactured by round steel or a round pipe, when a valve hand wheel is opened, each clamping jaw and the valve hand wheel only have one contact point, so that slipping is easy to cause, and particularly when a large-sized valve is opened and closed, the time for opening or closing the valve is prolonged due to the slipping. In this application, set up the annular groove on the outer peripheral face of first jack catch B's cylinder pole, because when opening and close the valve, first jack catch B is located the inboard of hand wheel rim, because the cross-section of hand wheel rim is circular or oval generally, the annular groove can block the inboard at the hand wheel rim, reduces the probability of skidding, improves the operating efficiency.
Further, the first jaw A has a clamping surface facing the first jaw B, and a linear groove extending in the direction of the second axis is formed in the clamping surface. After the linear grooves are formed, two groove walls can be formed on the clamping face of the first clamping jaw A, and the valve hand wheel mainly takes a circular ring shape, so that when the first clamping jaw A and the first clamping jaw B of the first valve spanner part are clamped on the valve hand wheel, two contact points can be formed between the outer side face of the valve hand wheel and the first clamping jaw A, the contact area between the first clamping jaw A and the valve hand wheel is increased, and slipping is avoided.
Further, this connecting rod and first jack catch A are the integral type structure that is L shape, and this first jack catch B adopts the screw thread mode to set up on the connecting rod. The first clamping jaws B are arranged on the connecting rod in a threaded mode, and the first clamping jaws B of different types can be replaced when needed, so that the valve hand wheel is suitable for valve hand wheels of special forms.
Further, second jack catch A and second jack catch B all are cylindricly, and the one end that connecting rod was kept away from to second jack catch A and second jack catch B all sets up to coniform. Because the second valve spanner portion is used for opening and close the miniature valve, set up second jack catch A and second jack catch B into cylindric back, still can open and close the valve comparatively smoothly, can also make full use of materials such as current round steel, reduce manufacturing cost.
Specifically, the distance between the first jaw A and the first jaw B is 80-90 mm, and the distance between the second jaw A and the second jaw B is 15-20 mm. Under the limitation, the first valve wrench part is used for opening and closing the hand wheel type valve with the size range of DN40-DN 400; the second valve handle is a hand-wheel type valve with opening and closing size range DN10-DN25, so that the hand-wheel type valve can be used for most of manually operated valve handles.
Further, a first bow spanner and a second bow spanner are arranged on the connecting rod, the first bow spanner protrudes along a third axis direction towards a direction far away from the connecting rod, the second bow spanner extends along the third axis direction and protrudes towards the direction far away from the connecting rod, the protruding direction of the first bow spanner is opposite to that of the second bow spanner, and the third axis direction is perpendicular to the first axis direction and the second axis direction; the first bow spanner is used for opening a first sealing cover of an inlet and an outlet of the 200L standard barrel, and the second bow spanner is used for opening a second sealing cover of an exhaust port of the 200L standard barrel. In petrochemical enterprises, most of containers for oil and solvent adopt 200L standard barrels, the standard barrels are provided with an inlet and an outlet and an exhaust port, a first sealing cover is screwed on the inlet and the outlet, the second sealing cover is screwed on the exhaust port, and when the first sealing cover and the second sealing cover are opened, the shape of the adopted wrench is similar to an arch, so the first sealing cover and the second sealing cover are called as an arch wrench, because the size of the wrench for opening the first sealing cover and the second sealing cover is different, and the bow-shaped wrench has no universal part with other wrenches, and needs to be arranged independently, the allocation amount of the wrench is increased, after the two bow-shaped wrenches for opening the first sealing cover and the second sealing cover of the 200L standard barrel are assembled on the combined valve wrench, the matching amount of the wrenches can be reduced, because the size of the bow-shaped spanner is smaller than that of the valve spanner, the inconvenience for carrying the combined valve spanner can not be caused.
