Abstract
The utility model provides a flow control valve. The flow control valve comprises an installation seat, a sliding sleeve, a temperature sensor, a spring and a sealing plug, wherein the installation seat is fixed in the position of a valve port and is provided with inner threads, the sliding sleeve is cylindrical, the spring is sleeved outside the sliding sleeve and is compressed, and the temperature sensor is connected with the sliding sleeve and is installed inside the installation seat along with the sliding sleeve with the spring. The sealing plug is barrel-shaped, the lateral wall of the sealing plug is provided with outer threads which are connected with the inner threads of the installation seat, and the temperature sensor is arranged at the top of the sealing plug due to the elasticity of the spring. When the temperature difference is large outdoors, the oil supply of a system when equipment is started at low temperature is guaranteed through a low-temperature by-pass pipeline control device, the problems that the equipment can not be started or breaks down in a short time after being started are avoided, the safety of products is improved, and the problem of oil supply is eliminated.
Description
Technical field
The utility model relates to a kind of flow control valve, is mainly used in a kind of valve in the oil circuit.
Background technique
The shortcoming of prior art is, at extremely frigid zones, it is excessively low because of oil temperature when causing device start that indoor/outdoor temperature-difference is excessive, and flowability is too poor and cause internal system for shortage of oil, thereby occurs that equipment can't normally start or generation fault in the short time after startup.Therefore, need a kind of special construction to guarantee under cryogenic conditions that equipment can normally start and can be because oil mobility be poor the generation fault.
The model utility content
In order to overcome above defective, the utility model provides a kind of flow control valve, and former pipeline is installed a bypass line, flow control valve is installed the valve port place of this bypass line, and during high temperature, this bypass line is obstructed; During low temperature, this bypass line can make the oil in the former oil pipe flow out from bypass line, directly enters equipment needed thereby.
For solving above technical problem, the utility model provides a kind of flow control valve, and described flow control valve comprises fitting seat, flip sleeve, temperature transducer, spring and shutoff; Fitting seat is fixed on the valve port place, and fitting seat has internal thread; Flip sleeve is Cylindrical object, and spring housing is at flip sleeve external compression spring, and temperature transducer is connected with flip sleeve, is installed in the fitting seat with flip sleeve with spring; Shutoff is barrel-shaped, and sidewall has outside thread, be connected with the fitting seat internal thread, temperature transducer since the elastic force effect top set of spring in shutoff.
Further, described flip sleeve one end has shoulder, and spring clip is at shoulder;
Further, the other end of described flip sleeve has radial slot.
Further, described temperature transducer has push rod, and this push rod top set is in shutoff.
Further, has gasket seal between described shutoff and the connecting base.
The utility model control valve structure can make equipment when the outdoor temperature difference is large, system's fuel feeding when making device start when the low temperature by low temperature bypass line control gear is guaranteed, generation failure problems in short time after the equipment of preventing can't start or start, promote the Security of product, got rid of the fuel feeding problem.

Mark is as follows among the figure: the 1-bypass line; The 2-fitting seat; The 3-flip sleeve; The 4-shutoff; The 5-push rod; The 6-temperature transducer; The 7-spring; The 8-gasket seal; The negotiable zone of 9-; 10-the first valve port; 11-the second valve port.
Arrow among the figure represents the direction that oil flows in pipeline.
Embodiment
As Figure 1-3, flow control valve comprises fitting seat 2, flip sleeve 3, temperature transducer 6, spring 7 and shutoff 4; Fitting seat 2 is fixed on the second valve port 11 places, and fitting seat 2 has internal thread; Flip sleeve 3 is Cylindrical object, and spring 7 is enclosed within flip sleeve 3 external compression springs 7, and temperature transducer 6 is connected with flip sleeve 3, is installed in the fitting seat 2 with flip sleeve 3 with spring 7; Shutoff 4 is barrel-shaped, and sidewall has outside thread, be connected with fitting seat 2 internal threads, temperature transducer 6 since the elastic force effect top set of spring 7 in shutoff 4.
The other end of flip sleeve 3 has radial slot.
Has gasket seal 8 between shutoff 4 and the connecting base 2.
As Figure 1-3, in the former pipeline direction of passing through that oils one bypass line 1 is set, this pipeline directly connects the oily equipment that needs, be provided with the first valve port 10 in bypass line 1 and former pipeline joint, and on bypass line 1, being provided with the second valve port 11 with the first valve port 10 opposite positions, the above two valve port is used for installing this flow control valve.Flip sleeve 3 is contained on the first valve port 10, and shutoff 4 is contained on the second valve port 11, utilizes temperature inductor 6 on the flip sleeve 3 and spring 7 to control flip sleeve 3 and slidably reciprocates at the first valve port 10 places.
As shown in Figure 1, be the unimpeded structure graph of the utility model flow control valve low temperature.Have among the figure and can find out, negotiable regional 9 maximums under this state are when the temperature transducer sense temperature is low, and the temperature transducer push rod contracts in temperature transducer.Under the low-temperature condition, oil mobility is very poor in the oil circuit, by bypass line, the oil in original oil circuit is drawn, and enters work system.
As shown in Figure 2, be the utility model flow control valve alternating temperature half-pass structure graph; As can be seen from the figure, when temperature raise to some extent, negotiable regional 9 under this state diminished, and namely the oily discharge value of this moment is less, and the overhang of temperature transducer push rod from temperature transducer is larger.This moment, temperature raise to some extent, and the oil mobility in the oil circuit is better, and a part of oil can normally enter work system by original oil circuit, and another part can directly enter work system by the oil pipe in the bypass line.
As shown in Figure 3, be the utility model flow control valve high temperature closure structure graph; As can be seen from the figure, under this state negotiable regional 9 is zero, the overhang of temperature transducer push rod from temperature transducer is maximum, promote flip sleeve, and then Compress Spring, flip sleeve realizes that with the complete shutoff of the first valve port the oil that has good fluidity in the oil circuit enters work system by original oil circuit under the condition of high temperature.
This flow control valve that the utility model provides, simple in structure, need not original pipeline is carried out large-scale transformation, only need install a bypass line additional, this flow control valve is installed, along with the variation of temperature, realize flow control.Have at oil under the condition of high temperature of good fluidity, bypass line is closed under the control of flow control valve, does not affect the normal operation of existing equipment, and is convenient and swift, saves cost.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
