Abstract
The utility model discloses a kind of low temperature valve stuffing box structure, including the stuffing-box of valve body neck is arranged on, supporting plate is welded with valve body neck；Muff is fixed on the supporting plate, and is connected with valve body top；In chamber between sleeve, supporting plate, valve body, set in opposite opened becket, becket and multiple electrically heated rods are set, temperature sensor is set in metal ring outer surface.The utility model is rational in infrastructure, by the heating of electrically heated rod, it is possible to prevente effectively from filler freezes with valve stem contacts position, it is ensured that valve at low ambient temperatures normal is used.
Description
Technical field
The utility model is related to a kind of low temperature valve stuffing box structure.
Background technology
The important technology requirement of Subzero valve is that at the stuffing-box of valve, i.e., filler cannot be below 0 with valve stem contacts position
DEG C, i.e., it can not freeze, once having tied ice, valve can not be opened and closed, it is impossible to realize function, with great dangerous hidden danger.It is logical at present
Be often using the design method for lengthening neck, but on the one hand because refrigerant is influenceed by transmission gap etc., plus length not enough, it is another
The winter environment temperature in the aspect north is very low, can nature icing.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, it is to avoid the low temperature that filler freezes with valve stem contacts position
Valve stuffing box structure.
Technical solution of the present utility model is：
A kind of low temperature valve stuffing box structure, it is characterized in that：Stuffing-box including being arranged on valve body neck, in the weldering of valve body neck
It is connected to supporting plate；Muff is fixed on the supporting plate, and is connected with valve body top；Chamber between sleeve, supporting plate, valve body
In, set in opposite opened becket, becket and multiple electrically heated rods are set, temperature sensor is set in metal ring outer surface.
Multiple electrically heated rods are set along becket even circumferential.Each electrically heated rod is controls to break respectively, logical form.
The utility model is rational in infrastructure, by the heating of electrically heated rod, it is possible to prevente effectively from filler and valve stem contacts position
Freeze, it is ensured that valve at low ambient temperatures normal is used.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is Fig. 1 A-A profiles.
Embodiment
A kind of low temperature valve stuffing box structure, including the stuffing-box 1 of valve body neck is arranged on, it is welded with support in valve body neck
Plate 2；Muff 3 is fixed on the supporting plate, and is connected with valve body top；In chamber between sleeve, supporting plate, valve body, set
Multiple electrically heated rods 5 are set in opposite opened becket 4, becket, temperature sensor is set in metal ring outer surface.
Multiple electrically heated rods are set along becket even circumferential.Each electrically heated rod is controls to break respectively, logical form.
During installation, first supporting plate, then the installation opposite opened gold between supporting plate and packing box flange are welded in valve body neck
Belong in ring, becket and multiple electrically heated rods are set, temperature sensor is set in metal ring outer surface；Then in becket outer cover
Upper muff.Temperature sensor sends temperature signal to electrically heated rod control device, by electrically heated rod control device according to temperature
The situation of change of degree, is also turned on multiple electrically heated rods or single electrically heated rod.
