Abstract

The utility model relates to a valve head, in particular to the valve head which is convenient to maintain and replace. The valve head comprises a valve rod, a valve head cover and a valve head main body, wherein a conical table is arranged at the end head of the valve rod, the ring-shaped valve head cover is mounted on the valve rod in a sleeving manner, the bottom of the valve head cover is in contact with the upper part of the conical table, the valve head main body is arranged at the lower part of the conical table, the valve head main body is connected with the valve head cover, and the valve head cover consists of two half-round cover bodies. As the ring-shaped valve head cover consists of the two half-round cover bodies, when the valve head isdisassembled, only the valve head main body needs to be disassembled from the valve head cover, the two cover bodies are separated to complete replacement work, and the valve rod does not need to be disassembled to take out the valve head cover from the valve rod, so that the valve head is more convenient to replace and maintain, the labor intensity is reduced, and the working efficiency is improved.

Description

A kind of valve head

Technical field

The utility model relates to a kind of valve head, is specifically related to a kind of valve head of convenient maintenance and replacement.

Background technique

Existing valve head generally adopts annular valve skull to be sleeved on valve rod, the structure that valve head lid is connected with valve head body; In the time that valve head body damages, valve head body is covered to the valve head body that separation more renews again by valve head, complete more changing jobs of valve head body.

But when valve head lid damages need to change time, valve rod need to be disassembled, then by valve head lid by taking out on valve rod, make more to change jobs loaded down with trivial details.

Model utility content

The purpose of this utility model is to provide a kind of dismounting and change valve head easily for problems of the prior art.

A kind of valve head; comprise valve rod, valve head lid, valve head body; described valve rod termination is provided with taper platform; described valve head lid is ring and is sleeved on valve rod; valve head lid bottom contacts with taper platform top; taper platform bottom is provided with valve head body, and described valve head body is connected with valve head lid, and described valve head lid is made up of two semicircular lids; The connecting part of described two semicircle lids respectively correspondence is provided with locating slot and locating stud;

Described lid and valve head body are bolted.

The utlity model has following beneficial effect:

1, because the valve head lid of ring is made up of two semicircular lids, when dismounting, only valve head body need be covered to dismounting by valve head, again two lids are separated and just can complete more and change jobs, and do not need to dismantle valve rod again by valve head lid by taking out on valve rod, make the repair and replacement of valve head more convenient, reduce labor intensity, increased work efficiency;

2, due to the connecting part of two semicircle lids respectively correspondence be provided with locating slot and locating stud, make in valve gap installation process location precisely convenient, be convenient to the installation of valve gap.

Embodiment

A kind of valve head as depicted in figs. 1 and 2, comprise valve rod 1, valve head lid 2, valve head body 3, described valve rod 1 termination is provided with taper platform 4, described valve head lid 2 is ring and is sleeved on valve rod 1, valve head lid 2 bottoms contact with taper platform 4 tops, taper platform 4 bottoms are provided with valve head body 3, described valve head body 3 is connected with valve head lid 2, described valve head lid 2 is made up of two semicircular lids 5, the connecting part of described two semicircle lids 5 respectively correspondence is provided with locating slot 6 and locating stud 7, and described lid 5 is bolted with valve head body 3.

Change when valve head, valve head body 3, by disassembling on valve head lid 2, then is separated two of valve head lid 2 semicircle lids 5, by taking off on valve rod 1; New valve head lid 2 and valve head body 3 are arranged on valve rod 1 and complete more and change jobs.
