Abstract
The utility model belongs to the valve technical field and particularly relates to a two-position three-way ball valve which comprises an end head, a ball-shaped valve core, a valve body, a valve rod and a handle. The ball-shaped valve core and the valve rod are arranged in the valve body, the ball-shaped valve core is connected with the valve rod, and the upper end of the valve rod extends the valve body and is connected with the handle. The end head is connected with the valve body, and a disk spring set is arranged between the end head and the valve body. A seal valve seat is arranged between the ball-shaped valve core and the valve body, the material of the ball-shaped valve core is stainless steel, and the material of the seal valve seat is polyether-ether-ketone (PEEK). The disk spring set is formed by reverse arrangement of four disk springs of the thickness of 0.5mm and two disk springs of the thickness of 0.4mm. The two-position three-way ball valve aims to solve the problems that normal use by people is affected because material defects of a valve core, a seal valve seat and a handle in an existing ball valve bring about bad sealing performance between the valve core and the seal valve seat and then service life of the existing ball valve is shortened and the handle is easily damaged and the like.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of two-position three way ball valve.
Background technique
Ball valve belongs to a kind of of valve, and wherein, spherical valve core is done the opening and closing that rotation reaches valve around the valve body center line.Ball valve is mainly used to make cut-out, distributes and change medium in pipeline flow direction.Now present, the spool of ball valve commonly used is made by copper and general stainless steel, and seal valve seat is made by poly-trifluoro polyethylene and compound fluoroplastic mostly, this is so that the creep between spool and the seal valve seat is heavier, wear-resisting relatively poor with bearing capacity, be easy to cause the wearing and tearing of seal valve seat, cause the sealability variation between spool and the seal valve seat, greatly shortened the working life of ball valve; In addition, ball valve adopts the dish reed to come transmission of pressure with the press seal valve seat usually, thereby make spool and seal valve seat good seal, existing dish reed group mostly is 0.45mm by 6 thickness sizes and the consistent dish reed of direction consists of, such structural design, in the process that medium flows into, the transmission of power is not steady, this has affected the sealability between spool and the seal valve seat to a certain extent, has greatly affected the normal use of ball valve; In addition, the handle that existing ball valve adopts phenolic resin to make mostly, such handle are easy to damage, and intensity does not satisfy requirement yet, affects very much people's normal use.
The model utility content
The purpose of this utility model: bring poor sealing performance between spool and the seal valve seat to cause shorten the working life of ball valve and handle easily damages and affects people's problems such as normal use in order to solve spool, seal valve seat and handle material defective that existing ball valve exists, and propose a kind of two-position three way ball valve.
The technical solution of the utility model: a kind of two-position three way ball valve comprises termination, spherical valve core, valve body, valve rod and handle; Described spherical valve core and valve rod are arranged in the valve body, and spherical valve core is connected with valve rod, and the upper end of valve rod is stretched out valve body and is connected with handle; Described termination is connected with valve body, and is provided with dish reed group between termination and the valve body; Be provided with seal valve seat between described spherical valve core and the valve body, it is characterized in that: described spherical valve core material is stainless steel; Described seal valve seat material is polyether-ether-ketone; Described dish reed group is the dish reed of 0.5mm and dish reed that 2 thickness sizes are 0.4mm by 4 thickness sizes and oppositely arranges and form.
A kind of two-position three way ball valve of the present utility model, the use of the seal valve seat of the spherical valve core of stainless steel and polyether-ether-ketone material, to the oil-free lubrication environment, in our experience and site trial, select the combination of PEEK and 316 stainless steels, improved creep resistant, wear-resisting and bearing capacity, thereby improved the sealability between spherical valve core and the seal valve seat, prolonged the working life of ball valve; In addition, employing is dish reed and 2 reverse dish reed groups that form that arrange of dish reed that thickness size is 0.4mm of 0.5mm by 4 thickness sizes, so that the transmission of power is very steady in the process that medium flows into, thereby guaranteed the sealability between spherical valve core and the seal valve seat, be very beneficial for people's normal use.
Further, described handle material is engineering plastics.
Adopt the handle of engineering plastics material, the intensity of handle is higher, and is not easy to damage, and is very beneficial for people's use.
Description of drawings
Fig. 1 is the embodiment's of a kind of two-position three way ball valve of the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model provides a kind of two-position three way ball valve, comprises termination 1, spherical valve core 2, valve body 4, valve rod 15 and handle 16; Spherical valve core 2 and valve rod 15 are arranged in the valve body 4, and spherical valve core 2 is connected with valve rod 15, and the upper end of valve rod 15 is stretched out valve body 4 and is connected with handle 16; Termination 1 is connected with valve body 4, and is provided with dish reed group 6 between termination 1 and the valve body 4; Be provided with seal valve seat 10 between spherical valve core 2 and the valve body 4, wherein, spherical valve core 2 materials are stainless steel; Seal valve seat 10 materials are polyether-ether-ketone; Handle 16 materials are engineering plastics; Dish reed group 6 is the dish reed of 0.5mm and dish reed that 2 thickness sizes are 0.4mm by 4 thickness sizes and oppositely arranges and form.
In the present embodiment, seal valve seat 10 materials are polyether-ether-ketone, polyether-ether-ketone has good in sliding properties, be suitable for being strict with the occasion of low coefficient of friction and abrasion performance purposes, particularly use the PEEK wear resistance of the slip trade mark of carbon fiber, graphite, PTFE modification very superior, that seal valve seat 10 adopts in this two-position three way ball valve is exactly polyether-ether-ketone PEEK.
