Abstract
The utility model relates to a mechanical temperature-controlling valve. Temperature controller is installed on one end of valve body, with the temperature controller is made up of external shell and temperature sensing part in the shell. The temperature sensing part expands or withdraws according to temperature. The temperature sensing part is connected with valve core of the valve body, and repositioning spring is arranged in the valve core. Opening level of valve port is changed under effect of the temperature sensing part and the repositioning spring. The utility model is characterized in simply structure, reliable work and easy maintenance. Due to automatic adjustment of opening level of the valve in accord with temperature of oil delivered as well as automatic adjustment of heating temperature, the utility model controls temperature of the oil easily, prevents increasing of delivery pressure resulting from coking of the oil in high temperature or too low temperature of the oil and reduces energy consumption largely.
Description
Technical field
The utility model relates to a kind of mechanical type temperature control apparatus, particularly a kind of mechanical type heat-operated valve that varies with temperature automatic control combustion gas, oil preheating furnace fuel channel break-make.
Background technique
At present, the crude oil in China part oil field is very glutinous, after pumping unit rises to ground with crude oil from the down-hole, becomes thicker because of the oil temperature descends, and can't carry at a distance, needs on the well side oven heating to be set.The fuel multiselect rock gas of oven, the needed delivery temperature of crude oil are generally realized by the air inflow that the workman handles manually-operated gate control rock gas.Its shortcoming is that artificial control is difficult to accomplish in time adjust air inflow with change of external conditions (as factors such as external temperature, wind-force, oil well oil pump capacity, gas pressure variations), all the time oily temperature control within the required range.Heating-up temperature is too high, and the easy coking of crude oil is extremely harmful to oven, also causes the waste of fuel simultaneously.Heating-up temperature is low excessively, and the oil transportation resistance is big, fragile oil-conveying device.If adopt the electrical equipment automatic control mode, abominable because of external environmental condition, safety reliability is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of and is active in one's movements, the mechanical type heat-operated valve of reliability height, energy saving.
The purpose of this utility model is achieved in that a kind of mechanical type heat-operated valve, comprise: valve body, spool, valve seat, it is characterized in that: control valve one end is provided with temp controller, temp controller can be varied with temperature in the housing by external casing and being arranged on and flexible temperature sensing part is formed, temperature sensing part is connected with the spool of valve body by link, temperature sensing part is subjected to thermal stretching can promote spool to move to the valve seat direction, reduce valve port opening, spool is provided with Returnning spring, temperature sensing part Yin Wendu descends when shrinking, effect lower valve core at Returnning spring oppositely moves, and increases valve port opening.Described valve seat is valve seat movably, and its underpart is provided with Returnning spring.
The utility model is the aperture of stretching control valve of utilizing temperature sensing part, promptly controls the inlet of combustion furnace fuel, if heated crude oil temperature is too high, the temperature sensing part elongation, the promotion spool moves down valve port is turned down, and the fuel inlet reduces, and crude oil temperature descends.Otherwise cross when low when crude oil temperature, its heat responsive element shortens, and under action of reset spring, promotes to move on the spool valve port is opened greatly, increases the inlet of fuel, the raising crude oil temperature.Can be within the required range by this valve with crude oil temperature control.
Characteristics of the present utility model are: simple in structure, reliable operation, easy to maintenance, can be according to the aperture of the automatic temperature control valve door of conveying crude oil, realize regulating automatically heating-up temperature, can control the temperature of crude oil like this, can not make the crude oil coking because of heating-up temperature is too high or not reach the warm transporting resistance, energy saving consumption significantly of increasing of oil of requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1; present embodiment has provided a kind of mechanical type heat-operated valve; can be used as gas or control valve for liquid fuel uses; mainly form by valve body 15, spool 7, valve seat 11 and temp controller; valve body one side is provided with fuel inlet 23 and outlet 22; being provided with in the valve body between fuel inlet and outlet can axially movable valve seat 11, and moving axially is in order to protect temperature sensing part, and preventing that Yin Wendu is too high does not have wider space and cause damage.Being provided with seal ring 10 between valve seat and the valve body, matches with spool in the top of valve seat, and the bottom is provided with Returnning spring 12, and spring is arranged between valve seat and the spring seat 13, is used for resetting of valve seat.The pretightening force of spring is adjusted by the nut 16 that is threaded with valve body, and the valve body low side is connected with bottom flange 21 and shutoff 14, is provided with seal ring 5 between valve gap and the shutoff.The top of valve seat is provided with spool, and valve core upper sleeve has spring 8, and the one end is against on the spring seat 9, the other end is against on the end face of spool enlarged diameter section, spring seat is fixedly connected on the valve body, and the top of spool is provided with the nut 6 that is threaded with valve body, in order to adjust the pretightening force of spring 8.The top of valve body is provided with flange 4 and bonnet 3, is provided with seal ring 5 between the two, connects by bolt 17.The housing 1 of temp controller is connected on the valve gap by screw 2, be provided with in the housing and can vary with temperature and flexible temperature sensing part 19, temperature sensing part is connected with the spool of valve body by the connecting rod 24 that passes bonnet and stretch in the valve body, the two ends that are connecting rod are against respectively between temperature sensing part and the spool, the outside of connecting rod is provided with guide sleeve 25, is provided with seal ring 18 between it and the valve gap.
Housing with temp controller during use is installed on the outlet conduit 20 that is heated crude oil, when the pipeline crude oil temperature is too high, and the temperature sensing part elongation, the promotion spool moves down, and compression reseting spring 8 turns down valve port A, and the fuel that enters oven reduces, oven flame diminishes, and crude oil temperature reduces.Cross when low when crude oil temperature, the temperature sensing part withdrawal promotes spool and moves up under action of reset spring, make valve port A become big, increases the inlet of fuel, and it is big that oven flame becomes, oily temperature rise.
Claims (2)
