Abstract

A limiting butterfly valve handle comprises a main handle and an auxiliary handle. The main handle is provided with a connecting table and a main handle spring fastener. The auxiliary handle is provided with a limiting part and a handheld part which are connected in a hinged mode. The connecting table is arranged in the middle of the main handle. An auxiliary handle connecting hole is formed in the connecting table. The two parts of the auxiliary handle are respectively provided with a main handle connecting hole which has the same size as the auxiliary handle connecting hole. The main handle and the auxiliary handle penetrate through the main handle connecting holes and the auxiliary handle connecting hole through rivets and are arranged on the connecting table in a connecting mode. The main handle spring fastener is designed in a cylinder shape. A concave position is arranged inwards on the lower-half portion of the cylinder shape. The limiting part is provided with a limiting block which is connected with a limiting groove formed in a limiting platform arranged on a butterfly valve body. An auxiliary handle spring fastener is arranged on the handheld part of the auxiliary handle. A spring is arranged on the handle through the main handle spring fastener and the auxiliary handle spring fastener in a connecting mode.

The spacing valve industry that relates to of this practicality, particularly a kind of spacing Handle of butterfly valve.

Background technique

In prior art, there is the technology of discloseder relevant Handle of butterfly valve, as the Handle of butterfly valve regulation structure of application number 201320250928.6 disclosed multistage adjustings, a kind of Handle of butterfly valve regulation structure of multistage adjusting is disclosed, comprise valve body and be fixed on the regulating handle on valve body top cover, it is characterized in that, the outward edge of described valve body top cover is provided with some notches, and the adjusting edge on described regulating handle snaps in described some notches and realizes multistage adjusting.This design snaps in the adjusting edge on regulating handle in the notch of diverse location, can control the keying mouth size of valve plate, realizes the function of multistage adjust flux., described some notches are ten notches, adjacent two notches are 10 ° with the central angle that the valve body top cover line of centres becomes, and adopt the words of this design can realize the spacing adjusting of 90 ° of scopes.

Application number is in 2008200778516.8 application documents, also to disclose Handle of butterfly valve, main is also the technical characteristics that embodies spacing butterfly valve, Handle of butterfly valve comprises handle, handle set and ratchet, the inside at handle rear portion is provided with ratchet, hinged between ratchet and handle, there is mounting hole the top center position of handle, handle is connected with valve rod by mounting hole, on described handle set, be provided with fixed hole, handle set is fixedly connected by fixed hole and butterfly valve body, in the top circumference of handle set, be provided with arc convex, the lower end surface of handle front portion and the top of handle set offset, handle front portion is provided with flange and handle is anterior and arc convex is slidably matched, on the circumference of the side of described handle set, be also provided with and be the tooth that arcuation distributes, described tooth and ratchet cooperatively interact, in prior art, also has similarly design, all the other correlation technique features on handle are disclosed, such as adopting drawing craft design, handle holds groove with hand, in use feel is fine, although this design can bring corresponding beneficial effect on some use, but all more complicated of cost of production and technique are not very desirable in overall price/performance ratio.

Summary of the invention

In order to make up the deficiency of product in prior art, a kind of spacing Handle of butterfly valve of the utility model special design, on production technology cost, also product relatively of the prior art is cheaper simultaneously can to realize convenient in use, can realize higher cost performance.

In order to achieve the above object, a kind of spacing Handle of butterfly valve, formed by main handle and secondary handle, on main handle, be provided with connected unit and main handle snak link, connected unit is arranged on main handle medium position, connected unit is provided with two, be symmetricly set on both sides, main handle middle part, in connected unit, be provided with secondary handle attachment hole, in each connected unit, be provided with two secondary handle attachment holes, on secondary handle, be provided with limit part and hold part, two-part are connected to hinged, two-part are provided with a main handle attachment hole, the consistent size of main handle attachment hole and secondary handle attachment hole, main handle passes main handle attachment hole with secondary handle by rivet and is connected and is arranged in connected unit with secondary handle attachment hole, main handle snak link cylinder design, cylindrical lower half portion is provided with recess inward, has unified into and has detained shape with top grouping, limit part is provided with limiting stopper, limiting stopper with on butterfly valve body upper limit platform, limited impression is set and is connected, hold and in part, be provided with secondary handle snak link, the design of secondary handle snak link geomery is consistent with main handle snak link, the recess opposite direction arranging on the recess arranging on secondary handle snak link and main handle snak link, spring is connected and is arranged on handle with secondary handle snak link by main handle snak link.

Secondary handle is held part and is provided with rubber pad groove with finger contact part, is provided with anti-skid rubber cushion in groove.

Above-mentioned anti-skid rubber cushion design can be with finger contact part, anti-slip tank design to be set by adopting secondary handle to hold part.

The beneficial effects of the utility model are, by the secondary handle design of hommization, adopt anti-skid rubber cushion design or adopt anti-slip tank design, can operate when in use more comfortable, with prior art in design reach similar technology effect in because simplicity of design, cost of production does not increase, cheaper than design of the prior art, overall price/performance ratio is just improved, and has made up the defect existing in prior art.
