Description
Technical field:
This utility model relates to ball valve, particularly relates to a kind of manual flanged ball valve.
Background technology:
Ball valve has only to the operation with 90-degree rotation and the least rotating torque just can be closed tight.The valve body of equality completely
Inner chamber is the runner that medium provides that resistance is the least, straight-through.It has been generally acknowledged that ball valve optimum directly does opening and closing and uses, but recent
Ball valve design has become to make it have throttling in development and control flow is used.Ball valve be mainly characterized by compact conformation own, easily
In Operation and maintenance, it is adaptable to general work media such as water, solvent, acid and natural gass, but also it is severe to be applicable to working condition
Medium, such as oxygen, hydrogen peroxide, methane and ethylene etc..Ball valve body can be overall, it is also possible to is knockdown.
Generally leakage phenomenon easily occurs between ball-valve valve rod installing hole and valve rod, cause ball valve in the bigger work of pressure
In environment, working effect is poor.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of manual flanged ball valve, simple in construction,
Volume is little, lightweight, and between valve rod installing hole and valve rod, sealing is excellent.
The technical solution of the utility model is as follows:
The valve that manual flanged ball valve, the left valve barrel installed including opposing seal and right valve barrel, left valve barrel and right valve barrel are constituted
Intracavity is provided with valve seat, left valve barrel and right valve barrel and is respectively arranged at two ends with the inlet and outlet being connected with valve pocket, is provided with in valve seat
Spheroid, it is characterised in that described left valve barrel upper end is provided with the installing hole being connected with valve pocket, installing hole inwall is provided with ring
Platform, the installing hole of land epimere is shoulder hole, is provided with the valve rod that lower end fixes with spheroid in installing hole, and valve rod upper end is installed
There is handle；
Valve rod hypomere outer wall is provided with in the installing hole below land the annular anticreep plate moved up and down, and valve rod is set with
The sealing ring coordinated is sealed with land,
It is provided with airtight and watertight padding, in annular gap between valve rod and shoulder hole hypomere on the valve rod above airtight and watertight padding successively
It is set with the mutually packing press ring of compression, disk spring, gland, spacing ring, is set with outside packing press ring and is placed on shoulder hole platform
Cushion seal pad on terrace.
Described manual flanged ball valve, it is characterised in that described valve rod and spheroid connecting portion are provided with anti-static device.
Described manual flanged ball valve, it is characterised in that be set with thrust washer on described valve rod, thrust washer is positioned at
Between anticreep plate and land.
The utility model has the advantages that:
This utility model simple in construction, volume are little, lightweight, by arranging sealing between valve rod installing hole and valve rod
Circle, airtight and watertight padding, packing press ring, disk spring, gland, spacing ring, cushion seal pad so that valve rod installing hole and valve stem seal
Property is excellent.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
See accompanying drawing:
Manual flanged ball valve, left valve barrel 1 and right valve barrel 2, left valve barrel 1 and the right valve barrel 2 installed including opposing seal are constituted
Valve pocket in be provided with valve seat 20, left valve barrel 1 and right valve barrel 2 be respectively arranged at two ends with the import 3 being connected with valve pocket and outlet 4, valve
Being provided with spheroid 5 in seat 20, left valve barrel 1 upper end is provided with the installing hole 6 being connected with valve pocket, and installing hole 6 inwall is provided with land
7, the installing hole of land 7 epimere is shoulder hole, is provided with the valve rod 8 that lower end fixes with spheroid, valve rod 8 upper end in installing hole 6
Handle 9 is installed；
Valve rod 8 hypomere outer wall is provided with in the installing hole below land the annular anticreep plate 10 moved up and down, on valve rod 8
It is set with and seals, with land, the sealing ring 11 coordinated,
Airtight and watertight padding 12, the valve rod above airtight and watertight padding 12 it is provided with in annular gap between valve rod 8 and shoulder hole hypomere
On be set with the mutually packing press ring 13 of compression, disk spring 14, gland 15, spacing ring 16, the outer suit of packing press ring 13 successively
Having the cushion seal pad 17 being placed on shoulder hole step surface, cushion seal pad 17 can improve sealing property, simultaneously further
It is also used as the buffer structure of disk spring.
Valve rod 8 and spheroid 5 connecting portion are provided with anti-static device 18.
Being set with thrust washer 19 on valve rod 8, thrust washer 19 is between anticreep plate 10 and land 7.
