Description
Technical field
The utility model relates to ball valve field, specially a kind of ball valve for preventing sealing High Pressure Difference and high leakage.
Background technique
Ball valve, the valve that opening and closing element (sphere) is driven by valve rod, and rotated around ball valve axis.Also it can be used for fluid
Adjusting and control, wherein firmly sealing its V-type core of V-type ball valve and the metal seat valve of pile-up welding hard alloy between have it is very strong
Shearing force, the medium especially suitable for fibre-bearing, small solid pellet etc..And multi-pass ball valve not only can be controlled flexibly on pipeline
The interflow of medium, the switching for shunting and flowing to, while any channel can also be closed and other two channel is made to be connected.This class valve
Door should be generally horizontally mounted in the duct.Ball valve is divided into according to driving method: pneumatic ball valve, electrical ball valve, manual ball valve.It passes
For the eccentric ball valve of system for generally using stream to close installation when High Pressure Difference, high-leakage grade, medium active force acts on valve completely
On core, spool and valve seat is made to be close to and play sealing function, sealing is the close contact realization by spool and sealing surface of seat, is let out
Leakage and differential pressure requirements are higher, and spool and sealing surface of seat just need to press tighter, are unfavorable for device work in this way.
Utility model content
The purpose of this utility model is to provide a kind of ball valves for preventing sealing High Pressure Difference and high leakage, to solve above-mentioned back
The problem of scape technology proposes.
To achieve the above object, the utility model provides the following technical solutions: one kind preventing sealing High Pressure Difference and high leakage
Ball valve, including valve rod, main valve body, platen, spring valve seat, spool, water inlet, gasket seal, fastening nut, auxiliary valve body, fill out
Expect gland, shaft and handle, the bottom end of the main valve body is equipped with the platen, and the bottom end of the platen is equipped with the water inlet,
The other side of the platen is equipped with the spring valve seat, and the other side of the spring valve seat is equipped with the spool, the spool
Bottom end is equipped with the gasket seal, and the other side of the spool is equipped with the valve rod, and the bottom end of the valve rod is equipped with the fastening
Nut, the other side of the valve rod are equipped with the gland, and the other side of the gland is equipped with the shaft, and described turn
The other side of axis is equipped with the handle.
Further, the water inlet is through setting in the main valve body.
Further, the spring valve seat and the spool are closely coupled.
Further, the gland and the auxiliary valve body are closely coupled.
Further, the shaft is flexibly connected with the handle.
Compared with prior art, the utility model has the beneficial effects that this kind prevents the ball of sealing High Pressure Difference and high leakage
Valve, relatively simple for structure, the sealing for spring valve seat utilizes the pressure of medium as long as spool and sealing surface of seat easily contact
The change of power push the spring valve seat is opened reliably to be sealed with spool, and pressure medium is bigger, and sealing is more reliable, and High Pressure Difference, high-leakage are wanted
Asking no longer is problem, and may further ensure that the leakproofness of device can guarantee by fastening nut by gasket seal
Stability of the device in operation.
