Description

A kind of flange seals three-way ball valve firmly
Technical field
The utility model relates to hard seal ball valve fields more particularly to a kind of flange to seal three-way ball valve firmly.
Background technique
This seven kinds of valves of gate valve, shut-off valve, plunger valve, butterfly valve, plug valve, diaphragm valve and ball valve account for about valve total amount 80% More than.Wherein ball valve is with fluid resistance is small, it is unrestricted to flow to, opening and closing is rapid and the low comprehensive performance of height is preferably excellent Point.The valve seat of existing ball valve is generally used the manufacture of the high molecular synthetic materials such as rubber, nylon and polytetrafluoroethylene (PTFE), uses temperature Lower than 200 DEG C, which limits the use scopes of ball valve.Made on the pipeline of many medium and high temperature media using high molecular material The hidden danger of failure is had for valve seat.The comprehensive performance of ball valve is improved using metal hard sealing structure using temperature and uses the longevity Life, is the needs of the systems such as chemical industry, petroleum, electric power, metallurgy, concentrated supply of heating in the city and long-distance transport pipes.Current hard seal ball valve In, the installation of sealing ring and elastic ring is not convenient.
Utility model content
The purpose of the utility model is to overcome the defect of the prior art, provides a kind of flange and seals three-way ball valve firmly, The technical solution is achieved in that
It includes valve body, flange ring, core core lower shaft, the first bolt group, valve rod, top that a kind of flange seals three-way ball valve firmly Plate.
The center of three sides of valve body is respectively equipped with circular perforations, and the valve inner bottom surface is equipped with firm banking. Limiting card is equipped at the top of the core, bottom is equipped with core lower shaft, and middle part is equipped with L shape channel.The core lower shaft and fixed bottom Seat forms cooperation, and the top plate is fixed by bolts on valve body, and the valve rod is removably consolidated with core, on the valve rod Under be equipped with limit protrusion be respectively held against top plate and core.
The flange ring is fixed by bolts in the side of valve body for being provided with circular perforations, and design has protrusion on flange ring Pipe, the protruding tube protrude into circular perforations and form cooperation, and the nearly core end of the protruding tube is equipped with spring groove, solid in the spring groove Determine spring, hard sealing ring is connected on the spring, the spring and hard sealing ring, which are set between protruding tube and core, to be formed Sealing.
Flange provided by the utility model seals three-way ball valve firmly, can be in many medium and high temperature media using hard seal means Pipeline on use.By the design of spring groove in protruding tube, so that spring and hard sealing ring is easy for installation.Three flange rings On be equipped with spring and hard sealing ring strengthens sealing effect.
Optionally, the spring is helical spring.
Optionally, the spring is disk spring.

Fig. 3 is the utility model flange ring schematic diagram;
Fig. 4 is the utility model core schematic diagram;
Fig. 5 is that the utility model flange seals three-way ball valve schematical top view firmly;
Appended drawing reference: 1- valve body, 11- firm banking, 12- circular perforations, 2- flange ring, 21- spring, the hard sealing ring of 22-, 23- protruding tube, 24- spring groove, 3- core, 31- limiting card, 32- core lower shaft, 33-L shape channel, 4- valve rod, 5- top plate.
Specific embodiment
As shown in Figs. 1-5, a kind of revealed flange of the utility model seals three-way ball valve, including valve body 1, flange firmly Ring 2,3 core lower shaft 32 of core, the first bolt group, valve rod 4, top plate 5.
The center of 1 three sides of valve body is respectively equipped with circular perforations 12, and 1 inner bottom surface of valve body is equipped with solid Determine pedestal 11.Limiting card 31 is equipped at the top of the core 3, bottom is equipped with core lower shaft 32, and middle part is equipped with L shape channel 33. The core lower shaft 32 is formed with firm banking 11 to be cooperated, and the top plate 5 is fixed by bolts on valve body 1, the valve Bar 4 and core 3 removably consolidate, and about 4 valve rod is equipped with limit protrusion and is respectively held against top plate 5 and core 3.
The flange ring 2 is fixed by bolts in 1 side of valve body for being provided with circular perforations 12, and protruding tube 23 protrudes into Circular perforations 12 form cooperation, and nearly 3 end of core of the protruding tube 23 is equipped with spring groove 24, fixes in the spring groove 24 Spring 21, hard sealing ring 22 is connected on the spring 21, and the spring 21 is set to protruding tube with hard sealing ring 22 Sealing is formed between 23 and core 3.
Flange provided by the utility model seals three-way ball valve firmly, can be in many medium and high temperature media using hard seal means Pipeline on use.It is designed by the spring groove 24 in protruding tube 23, so that the installation side of spring 21 and hard sealing ring 22 Just.It is equipped with spring 21 on three flange rings 2 and hard sealing ring 22 strengthens sealing effect.
In specific implementation, the spring is helical spring.
Embodiment is only one embodiment of the utility model, for those of ordinary skill in the art, is not being paid Under the premise of creative labor, other embodiments can also be obtained with reference to the accompanying drawings, also within protection scope of the present invention.
