Description

A kind of valve handle

Technical field

The utility model belongs to valve technology field, is related to a kind of valve handle.

Background technology

In standard gb/t21465-2008 " valve term ", valve is defined as: for medium in control pipeline, have The engineering goods of movable agency overall.Valve can be divided into gate valve, stop valve, choke valve, ball valve, butterfly valve, cock by structure Valve and check-valves etc., wherein opening and closing element have gate valve, stop valve, ball valve, butterfly valve and plug valve etc. by the valve that valve rod drives.At this In the valve that a little opening and closing elements are driven by valve rod, valve element is typically mounted in valve body, and valve rod the inner is connected with valve element, the outer end of valve rod Stretch out valve body to be fixedly connected with handle, rotate often through turning handle band ovable valve stem during control valve.

Chinese patent literature data is open to propose a kind of valve handle [application number: cn201020145702.6；Authorize public Announcement number: cn201661760u], a kind of valve handle, including the handwheel handle being made of plastics, handwheel handle is provided with energy and valve The connecting portion that bar connects and rotates with ovable valve stem, connecting portion has the connection end of projection, connects between connection end and handwheel handle It is connected to several reinforcements, reinforcement can strengthen the intensity of above-mentioned connection end and handwheel handle respectively.Handwheel handle is to have sky The housing in chamber, housing has opening, and cavity is connected with the external world by opening.

This valve handle is fixedly connected with valve rod by connecting portion, rotate handwheel handle when just can carry ovable valve stem rotation from And realize the regulation of valve.This handwheel improves the knot between the handwheel handle that connecting portion and plastics are made by arranging reinforcement Structure intensity thus improving the service life of handwheel, but at the opening of housing made of plastics often with valve body close to and compared with other Regional structure low intensity, often because colliding with or the reason such as aging occurs damaging, thus dropping at first during using The low service life of handwheel.

Content of the invention

The purpose of this utility model be the problems referred to above existing for prior art it is proposed that a kind of valve handle, solve Technical problem be how to improve the service life of valve handle.

The purpose of this utility model can be realized by following technical proposal:

A kind of valve handle, including the handle body being made of plastics it is characterised in that described valve handle is also included by gold Belong to the tubular quoit that material is made, the lower surface of described handle body is arranged fluted, on the side surface of described groove There is connecting portion, described quoit is plugged on connecting portion and quoit is fixedly connected with connecting portion, the lower end of described quoit External in handle.

Valve includes valve body, is provided with valve element in valve body, and valve element is connected with valve rod, and the outer end of valve rod passes valve body and hand Handle is fixedly connected.In order to be connected handle with valve rod, handle body is often additionally provided with the junction surface being connected with valve rod, valve rod is general Lower end through handle body is connected with junction surface, and the lower end of handle body is then close to valve body.During handle body injection mo(u)lding First quoit can be arranged in mould, then handle body is welded together with quoit injection；Can also note in handle body When not solidifying completely after moulding, the upper end of quoit is inserted in groove, by the expansion and contraction of material by quoit and handle The connecting portion of body is fixedly connected；Again quoit can also be assemblied in the lower end of handle body by glue by first injection mo(u)lding handle body It is adhesively fixed；Or the handle body of forming and quoit are carried out close-fitting installation.Handle body is by injection molding, metal Circle is made up of metal material, the such as corrosion resistant material such as stainless steel, platinum or titanium alloy.By metal material make in cylinder The quoit of shape, structural strength is high, and the upper end of quoit is plugged on the connecting portion of groove-side surface and is fixedly connected, Ke Yizeng Plus the structural strength of handle body lower end, thus improve the service life of handle；The lower end of quoit is not easy to send out in handle in vitro Raw breakage and deformation, can improve the service life of valve handle.
