Abstract
The utility model relates to a small -bore high -pressure all -welded ball valve, including disk seat, spring, spheroid and valve body, in the valve body was located to the spheroid, spheroidal upper and lower trip all was equipped with the disk seat, all installs the spring among the media channel of the upper and lower trip of valve body, the protruding neck that extends among the oriented media channel of disk seat one end, and the one end top of spring makes disk seat and ball sealing cooperation on protruding neck, and the thickness of valve body is greater than media channel's diameter, and media channel be the step hole, and the other end of spring pushes up on the step face in media channel. The utility model discloses a less spare part, compact structure, sealed reliable has improved the pressure rating that small -bore valve used, be particularly useful for city gas conveying pipe network.
Description
Technical field
This utility model is related to universal machine valve technology field, more particularly to a kind of small-bore high pressure all-welded ball valve.
Background technology
Valve is the equipment for opening and closing pipe path or adjust pipeline medium flow.Therefore it is required that the mechanical strength of valve body
Height, flexibly, seal member is tightly durable for rotatable parts.All-welded ball valve refers to ball of the valve body structure using Integral welded structure
Valve.The pressure that existing city gas pipeline valve spool of valve is received is less than normal, poor sealing performance, the applicable pressure rating model of valve
Enclose narrow.
Utility model content
To solve above-mentioned technical problem, this utility model aims to provide a kind of small-bore high pressure all-welded ball valve, and sealing can
By, compact conformation.
To reach above-mentioned purpose, the technical scheme that this utility model is taken is as follows：
A kind of small-bore high pressure all-welded ball valve, including valve seat, spring, spheroid and valve body, the spheroid is located in valve body,
The upstream and downstream of the spheroid are equipped with valve seat, and spring, the valve seat one are mounted in the medium channel of the upstream and downstream of valve body
The convex neck extended in the guided media passage of end, one end of spring withstands on and make on convex neck valve seat with ball seal cooperation, the medium
Passage is stepped hole, and the other end of spring is withstood on the step surface in medium channel.
Further, more than the diameter of medium channel, the body base central authorities are provided with communicating valve to the thickness of the valve body
The valve rod installing hole in chamber, the diameter with diameter greater than valve rod of the valve rod installing hole is provided with plug in the valve rod installing hole.
Further, the plug is welded with valve body.
Further, the spring is helical spring.
Further, the valve rod and spheroid clamping.
Further, the lower end that the spheroid top surface has a word groove, valve rod is stuck in a word groove.
Compared with the prior art, this utility model has the advantage that and beneficial effect：
This utility model adopts less parts, and compact conformation, sealed reliable improve the pressure that smaller diameter valve is used
Power grade, is particularly suited for gas transmission pipeline network.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- valve seats, 2- springs, 3- spheroids, 4- valve bodies, 5- medium channels, the convex necks of 6-, 7- valve rods, 8- plugs.
Specific embodiment
To make the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing, to this practicality
It is new to be further elaborated.
As shown in figure 1, small-bore high pressure all-welded ball valve disclosed in this utility model, including valve seat 1, spring 2, spheroid 3
With valve body 4, in valve body 4, the upstream and downstream of spheroid 3 are equipped with valve seat 1, the medium channel 5 of the upstream and downstream of valve body 4 to spheroid 3
In be mounted on spring 2, the convex neck 6 extended in one end guided media passage 5 of valve seat 1, one end of spring 2 withstands on and made on convex neck 6
Valve seat 1 coordinates with the sealing of spheroid 3, and spring 2 is helical spring.Preferably, diameter of the thickness of valve body 4 more than medium channel 5,
The diameter with diameter greater than valve rod 7 of valve rod installing hole, is provided with plug 8 in valve rod installing hole, plug 8 is welded with valve body 4.Medium leads to
Road 5 is stepped hole, and the other end of spring 2 is withstood on the step surface in medium channel 5.It is certain, the full solder sphere of small-bore high pressure
Valve also includes valve rod sealing member and valve seat insert, and valve rod sealing member is enclosed within valve rod 7, and valve rod sealing member is located at valve rod 7 and valve
Between body 4, valve seat insert is located between valve seat 1 and valve body 4.
This utility model increases a helical spring after valve seat, increases the pretightning force of valve base sealing, makes the close of valve
The larger improvement of Feng Xingyou, is adapted to higher pressure environment.Because of higher pressure environment, valve body wall thickness is necessarily increased,
Valve rod can not be loaded by valve pocket, therefore be provided with the valve rod installing hole of connection valve pocket in the bottom center of valve body 4, be installed by the valve rod
Hole loads valve rod 7, and then welding plug 8 seals up the valve rod installing hole in valve rod installing hole.Valve rod 7 and the clamping of spheroid 3,
The lower end that the top surface of spheroid 3 has a word groove, valve rod 7 is stuck in a word groove.
This utility model adopts less parts, simpler structure, improves pressure that smaller diameter valve is used etc.
Level, improves the sealing reliability of valve.This utility model sealed reliable, compact conformation, meet green production theory.
Certainly, this utility model can also have other various embodiments, spiritual and its essence without departing substantially from this utility model
In the case of, those of ordinary skill in the art can make various corresponding changes and deformation, but these phases according to this utility model
The change and deformation answered should all belong to the scope of the claims appended by this utility model.
