Description
Technical field
The utility model relates to a kind of valve, in particular to a kind of Fluorine-lined direct-operated regulators.
Background technique
Direct-operated regulator is to rely on the pressure, temperature that flow through medium itself in valve as driven by energy valve automatic work
Regulating valve.But direct-operated regulator is easy to exist in the long-term use and adjusts sensitivity deficiency, poor sealing performance
Problem causes direct-operated regulator service life relatively low, and using effect is poor.
Utility model content
The purpose of this utility model is to provide for a kind of Fluorine-lined direct-operated regulator, and the regulating valve structure is simple, installation
It is easy to use, it is at low cost, the sealing performance of regulating valve is improved by multi-layer sealed setting, and set by unique sleeve
Meter, so that the adjusting sensitivity of regulating valve is obviously improved, improves the service life and using effect of regulating valve.
In order to achieve the above object, the utility model provides following technical solution: a kind of Fluorine-lined direct-operated regulator, packet
It includes valve body, spool, sleeve, bellows, valve deck, spring, spring base and adjusts screw, the sleeve is pressed into the top of valve body and leads to
It crosses valve deck and bolt is fixed, the sleeve and the lower part of valve rod junction are sealed by bellows component, and top is logical
It crosses tetrafluoroethene fill block to be sealed, the lower spring end is mutually butted on sleeve, and upper end is mutually butted on spring base, under the adjusting screw
It holds connecting spring seat and is threadedly coupled valve deck, the lower part of the sleeve is equipped with several pores of connection valve outlet.
It is further preferred that being equipped with gap between the corresponding valve interior wall of the pore and sleeve.
It is further preferred that the quantity of the pore is two groups, and every group of pore is circumferentially uniformly distributed along sleeve.
It is further preferred that the lower end of the sleeve is connected and sealed by the valve seat of sealing bayonet and valve body.
The utility model has the beneficial effects that the regulating valve structure is simple, and it is easy to install and use, it is at low cost, it is close by multilayer
Envelope setting improves the sealing performance of regulating valve, and by unique sleeve design, so that the adjusting sensitivity of regulating valve is aobvious
It writes and is promoted, improve the service life and using effect of regulating valve.

Specific embodiment
We are described further a kind of Fluorine-lined direct-operated regulator described in the utility model in conjunction with attached drawing below.
As shown in fig. 1, a kind of Fluorine-lined direct-operated regulator of the present embodiment, including valve body 1, spool 2, sleeve 3, ripple
Pipe 4, valve deck 5, spring 6, spring base 7 and adjusting screw 8, the sleeve pressure 3 enter the tops of valve body 1 and by valve deck 5 and bolts 9
It is fixed, the sleeve 3 and the lower part of 10 junction of valve rod are sealed by 4 component of bellows, and top passes through tetrafluoro second
Alkene fill block 11 is sealed, and 6 lower end of spring is mutually butted on sleeve 3, and upper end is mutually butted on spring base 7,8 lower end of adjusting screw
Connecting spring seat 7 and threaded connection valve deck 5, the lower part of the sleeve 3 are equipped with several pores 31 that connection valve body 1 exports.It is described
The lower end of sleeve 3 is connected and sealed by sealing bayonet 33 and the valve seat of valve body 1.The service condition of the regulating valve is substantially such as
Under: during liquid flows through valve body, pressure is improved to spool, so that spool and valve rod shift up, since spring mentions downwards
The more big spring compression of arch thrust, spool and displacement of valve rod is bigger, and the thrust provided is bigger, when the thrust and liquid of spring offer
When the pressure of offer is equal, spool and valve rod stop displacement, to achieve the purpose that adjust flow according to liquid pressure, according to tune
The initial compression degree for saving screw adjustment spring can final regulation valve body circulation efficiency under different liquids and flow condition.It is logical
The setting for crossing pore improves the sensitivity for adjusting valve regulation, and liquid is more steady for the pressure of spool, height when being not in
When low situation.
In the present embodiment, gap 32 is equipped between corresponding 1 inner wall of valve body of the pore 31 and sleeve 3.The pore 31
Quantity be two groups, and every group of pore 31 is uniformly distributed along sleeve 3 is circumferential.Be conducive to reduce impact of the liquid to valve interior wall,
Prolong the service life.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
