Abstract

The utility model relates to a valve which is used for stopping or opening pipelines, particularly a novel valve which is opened and closed by rotating a valve core. The disadvantages of complex structure, slow opening and closing speed and big volume of the valve used in the prior art are mainly solved by the utility model. The utility model is mainly characterized in that a structure which rotates along a horizontal shaft is adopted by the valve core, and the opening and the closing of the valve are obtained. The utility model has the advantages of simple structure, small volume, low cost, etc. The utility model is an ideal valve structure, and is widely used in various pipelines.

Description

A kind of valve

The utility model relates to a kind of valve that is used for pipeline cut-off or opens, and is particularly a kind of simple in structure, depends on valve core rotation to reach the novel valve of quick open and close.

Prior art is used valve, commonly is out, to open speed slow, and valve body inner structure complexity, volume is bigger, poor reliability during use, the manufacture cost height can not satisfy the needs of use.

The purpose of this utility model be the design a kind of simple in structure, volume is little, easily manufactured, cost is low, use novel valve fast, easily.

The purpose of this utility model is to realize like this, novel valve is made up of valve body, valve seat, spool and control mechanism, on valve seat, have one group of through hole, on spool, have one group of through hole identical with valve seat, spool one side and valve seat is coaxial links, opposite side and holddown spring join, the spool control mechanism can make spool form around the driving mechanism of rotational by handle control, driving mechanism is made up of gear ring, gear and rotatingshaft, gear ring connects with spool, while and gear engagement, rotatingshaft one end connects with gear, and the other end connects with handle.

The utility model compared with prior art has simple in structure, low cost of manufacture, an advantage such as the valve volume is little, opening speed is fast.

Below in conjunction with accompanying drawing the utility model is described.

Accompanying drawing 1 is the utility model embodiment 1 schematic representation.

Accompanying drawing 2 is the utility model embodiment 2 schematic representation.

Referring to accompanying drawing 1, valve 2 is installed in the valve body 1, for reducing number of spare parts, valve seat 2 and valve body 1 can be made one, on valve seat 2, have one group of hole 4, hole 4 communicates with valve inlet hole 11 simultaneously, the center shrinkage pool of valve seat 2 and the central protuberance of spool 3 link, make valve seat 2 and spool 3 central positions constant, the another side of spool 3, by holddown spring 6 effects, valve seat 2 is closely contacted with spool 3 sides, keep sealing, for spool 3 is rotated flexibly, between holddown spring 6 and spool 3, be provided with pressure bearing 12, gear ring 8 is fixed on the spool 3, with gear 9 engagements, rotatingshaft 10 1 ends connect with gear 9 simultaneously, and the other end connects with handle 7, during use, move handle 7, rotatingshaft 10, gear 9 driven gears 8 rotate spool 3, when the hole 4 on hole on the spool 35 and the valve seat 2 misplaces fully, hole 5 is closed state with hole 4, this moment valve for closing, otherwise valve is an opening state, and along with hole 4 area that communicates with hole 5 increases, the valve opening amount increases, and 4 overlap fully with hole 5 up to the hole, and valve is maximum opening state, the utility model also can adopt accompanying drawing 2 structural types, holddown spring adopts butterfly spring 13, and butterfly spring 13 is through joining shaft 14 and spool 3 scyewed joint, when spool 3 is in unlatching, because joining shaft 14 connects threaded function with spool 3, make butterfly spring 13 be in original-shape, pressure reduces, otherwise butterfly spring 13 is in resiliently deformable, pressure increases.

The utility model embodiment has advantages such as simple in structure, that cost is low, volume is little, opening speed is fast through facts have proved, is a kind of comparatively ideal novel valve structure, can extensively use in various pipelines.
