Abstract
The utility model gudgeon ball valve belongs to technical field of valve manufacturing.Gudgeon ball valve comprises: support ring, guide ring, belleville spring, thrust washer, O type circle, packing ring, front valve seat frame, front valve seat, rear valve base, rear valve base frame, termination, end seal ring, valve body, ball socketed bearing, stem bearing, panel nut, spheroid, the secondary support ring of valve rod, the main support ring of valve rod, valve rod, handle etc.Left end connects the O type circle at place, is shifted to the right to the right-hand member of belleville spring; Front valve seat material changes polyether-ether-ketone (PEEK) into by polychlorotrifluoroethylene (PCTFE), and rear valve base size increases; Belleville spring gives valve seat pretightening force, makes sealability better, especially, in the larger situation of range of temperature, can compensate the variation of the active force on the sealing surface bringing because of valve seat deformation; Valve rod bottom has increased ball socketed bearing.Front valve seat of the present utility model can be not only by the pretightening force of spring, can also be by gas pressure the thrust on O type circle, make sealability more reliable, material changes polyether-ether-ketone (PEEK) into, strengthened wear resistance, frictional loss reduces, and increases the service life; Increase ball socketed bearing, avoid intermetallic directly to contact, improve operating handle.
Description
Technical field
The utility model belongs to technical field of valve manufacturing.
Background technique
Ball valve is that open-shut device is a spheroid, utilizes spheroid to rotate to realize opening and closing around the axis of valve rod.Ball valve is mainly used in cut-out, distributes and changes media flow direction.The advantages such as it is little that ball valve has fluid resistance, and sealing is reliable, opens and closes fast, and operational torque is little, are widely used in the industries such as machinery, chemical industry, oil.
Ball valve is divided into floating ball valve and fixing ball valve by structural type.In floating ball valve, spheroid floats, and under pressure medium effect, spheroid can produce certain displacement and be pressed on the valve seat of outlet end, ensures outlet end sealing, is widely used under mesolow operating mode.In fixing ball valve, spheroid is fixed, and does not produce movement after pressurized, ensures the sealing of valve by the pretightening force of spring, is widely used under high pressure operating mode.
Conventionally tee ball valve is used for changing media flow direction, and bottom is import, and two side ends is outlet.But actual gas-fueled vehicles gas station operating mode is special, need be from the left end air inlet of tee ball valve, give vent to anger in bottom, and right-hand member loses heart.Gas-fueled vehicles gas station, pressure, up to 20Mpa, belongs to high pressure operating mode, conventionally selects fixed tee ball valve (gudgeon ball valve).The gudgeon ball seat material of conventional construction is polychlorotrifluoroethylene (PCTFE), and under the operating mode of high voltagehigh frequency rate operation, obviously, Life cycle is short, is generally one month in wearing and tearing.
Model utility content
Not good in order to solve gudgeon ball seat wear resistance, cause the short shortcoming of valve bulk life time, it is the gudgeon ball valve of polyether-ether-ketone (PEEK) that the utility model provides a kind of front valve seat material.
For achieving the above object, technical solution adopted in the utility model is as follows:
Described gudgeon ball valve comprises: support ring, guide ring, belleville spring, thrust washer, O type circle, packing ring, front valve seat frame, front valve seat, rear valve base, rear valve base frame, termination, end seal ring, valve body, ball socketed bearing, stem bearing, panel nut, spheroid, the secondary support ring of valve rod, the main support ring of valve rod, valve rod, handle etc.
Described left end connects the described O type circle at place, is shifted to the right to the right-hand member of described belleville spring, not only can prevent valves leakage, can also be by the thrust of gas, act on described valve seat frame, and make described valve seat near described spheroid, sealability is more reliable.
Described front valve seat material changes polyether-ether-ketone (PEEK) into by polychlorotrifluoroethylene (PCTFE), and described rear valve base size increases.
Described belleville spring gives described valve seat pretightening force, makes sealability better, especially, in the larger situation of range of temperature, can compensate the variation of the active force on the sealing surface bringing because of described valve seat deformation.
Described valve rod bottom has increased described ball socketed bearing, can avoid intermetallic direct contact, improves operating handle.
The beneficial effects of the utility model are:
(1) the O type circle at the left end place of connecing is shifted to the right to belleville spring right-hand member, front valve seat can be not only by the pretightening force of spring, can also be by gas pressure the thrust on O type circle, make sealability more reliable.
(2) front valve seat material changes polyether-ether-ketone (PEEK) into, strengthens the wear resistance of valve seat, and frictional loss is reduced, and increases the service life.
(3) rear valve base material is constant, but strengthens the excircle dimension of valve seat, makes wear resistance more lasting.
(4) valve rod bottom increases ball socketed bearing, avoids intermetallic directly to contact, and improves operating handle.

Embodiment
O type circle 21, the secondary support ring 22 of valve rod, the main support ring 23 of valve rod and stem bearing 18 are enclosed within on valve rod 24; groove and spheroid 20 by bottom are located by connecting; the secondary support ring 22 of valve rod is to 21 buffer functions of O type circle; protect O type circle and avoid valve rod 24 too much to contact and cause intermetallic interlock with valve body 16 endoporus, stem bearing 18 is for avoiding metal directly to contact.
Ball socketed bearing 17 is installed on valve rod 24 bottoms and spheroid, and Shang Xia 20 two ends, avoid intermetallic directly to contact, and improve operating handle.
Front valve seat frame support ring 1, guide ring 2, belleville spring 3, thrust washer 4, O type circle 5 and packing ring 6 are enclosed within on front valve seat frame 7 successively; belleville spring 3 gives front valve seat 8 pretightening forces; packing ring 6 is during for air inlet; protection O type circle 5 is under high pressure torn; thrust washer 4 prevent O type circle 5 released gas impact, produce skew.
Belleville spring 3, guide ring 2, O type circle 12, rear valve base frame support ring 13 are enclosed within on rear valve base frame 10 successively, and belleville spring 3 gives rear valve base 9 pretightening forces, and O type circle 12 prevents right output port leakage.
Termination 14 is threaded connection with valve body 16, and compression end seal ring 15, prevents that two ends from leaking outside.
Gas-fueled vehicles gas station, adopt this gudgeon ball valve, gas is from left port air inlet, gives vent to anger in bottom, and bottom connects a tracheae, insert on the oil cylinder on automobile, open the valve gudgeon ball valve therewith on oil cylinder, start aerating, after gas is filled it up with, close the valve on oil cylinder, the residual air in the tracheae of bottom is released by gudgeon ball valve right output port.
