Description
【Technical field】
The utility model is related to a kind of needle-valve, more particularly to a kind of integral type forging needle-valve.
【Background technology】
Needle-valve is one kind of throttle valve, is widely used since degree of regulation is higher by people, and the valve plug of needle-valve is in pin
Shape, and acted along the direction of fluid, it is accumulated by adjusting the cooperation of valve plug and valve base chamber on valve rod to change flow section, from
And adjust or block fluid flow.Existing needle-valve is in use, promote valve rod of needle valve to go deep into valve seat, valve plug is matched somebody with somebody with valve base chamber at this time
Conjunction is becoming tight, and the sectional area of fluid outlet becomes smaller, and fluid flow becomes smaller therewith；When valve plug and valve base chamber are fitted close, stream is blocked
Body flow；However when normally using existing needle-valve, often do not know that valve rod of needle valve is advanced to that degree can just make
The valve plug of needle-valve is fitted close with valve seat, and the situation that valve plug crosses position easily occurs, reduces the service life of needle-valve, can be damaged when serious
Bad fluid inlet and outlet, therefore, it is proposed that this novel integrated forging needle-valve.
【Utility model content】
The main purpose of the utility model is that providing a kind of integral type forging needle-valve, can effectively solve in background technology
The problem of.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of integral type forging needle-valve, including main body, valve rod, lower gasket, valve stem nut, handle, positioning seat and snap ring institute
It states middle part in main body and is equipped with valve rod, the valve stem tip is equipped with snap ring, and the bottom of the snap ring is equipped with positioning seat, the positioning
The bottom of seat is equipped with valve stem nut, and the valve rod runs through valve stem nut and positioning seat, is equipped between the valve stem nut and valve rod
Filler, the bottom of the filler are equipped with O-ring, and the bottom of the valve stem nut is equipped with lower gasket, and the top of the main body is equipped with
Handle and handle are wrapped in the periphery of main body.
Further, O-ring is felt seal.
Further, the main body and handle are all made of stainless steel material.
Further, the one side of the positioning seat is equipped with trip bolt.
Compared with prior art, the utility model has the advantages that：This kind of integral type forging needle-valve, major part
All made of stainless steel material, it is wear-resistant, it is not easy to get rusty, extends the service life of needle-valve, in valve rod of needle valve nut bottom
Lower gasket is provided with, due to the cushioning effect of lower gasket, reduces friction of each stroke to filler, by setting snap ring, valve
The maximum range of bar is fixed, and so as to promote valve rod when was not in the situation of position, and effectively raised when shutting off
Leakproofness extends the service life of needle-valve, and by setting handle, it is convenient to be provided in the installation of needle-valve and disassembly process,
Handle both ends are locked by trip bolt, and firm durable, O-ring is felt seal, and the leakproofness and fastness of felt seal compare one
As sealing ring to get well, and non-aging, service life is long.
【Description of the drawings】
