Abstract
The utility model relates to a drain valve for a compressor, which is characterized by comprising a valve body (1). The valve body (1) possesses a step-shaped central through hole, the internal and external surfaces of one end of the valve body (1) are provided with threads, the step surface of the central through hole of the valve body (1) is provided with a spring (3), a steel ball (4) and a hollow screw plug (5) in sequence, the hollow screw plug (5) is connected to the inner screwed hole at the end portion of the valve body (1), and the spring (3) and the steel ball (4) are package in the step-shaped central through hole. According to the utility model, the beneficial effect is that after the drain valve is additionally provided, the drain valve doesn't work under a normal exhaust pressure. And when there is liquid, the exhaust pressure exceeds the rated exhaust pressure, the drain valve is open, liquid is drained from the drain valve, and the exhaust pressure returns to the normal value.
Description
Technical field
The utility model relates to and is used for LPG and the more gas compressor of rock gas heavy ends, and especially a kind of compressor is used liquid discharging valve.
Background technique
The working principle of compressor is: through changing piston position in cylinder, realize the variation of the pressure of compressed medium (being LPG or rock gas gas).To be compressed gas get in the cylinder from suction valve its flow process, because the motion of piston, gas is pressurized, and when pressure during greater than the pressure outlet valve outside, gas is through the outlet valve outflow;
Because the situation of portion gas liquefaction all takes place above-mentioned compressed medium easily, after the gas that contains liquid got into cylinder, liquid was can not be compressed in compression process, and air valve is because the restriction of passage can only allow the liquid of trace to pass through.The phenomenon that will take blame for others like this causes a serious accident.
The model utility content
The purpose of the utility model is exactly the problems referred to above that exist in the existing design in order to overcome, and provides a kind of compressor to use liquid discharging valve, makes the compressor operating safety and reliability, improves the working life of compressor.
The utility model solves the technological scheme that its technical problem adopted:
Compressor is used liquid discharging valve; It is characterized in that: comprise valve body; Valve body has step-like central through bore, and the inner and outer surface of valve body one end is provided with screw thread, is provided with spring, steel ball, hollow screw plug on the step surface of valve body central through bore successively; Said hollow screw plug is connected with the interior threaded hole of valve end, and described spring, steel ball are encapsulated in the step hole.
On the basis of above-mentioned main technical schemes, can increase following further perfect technological scheme:
Described step surface is the conical surface, and the conical surface is provided with pad, and described spring is placed on the pad.
The other end of described valve body is provided with flat mouthful groove along diametric(al).
The contact jaw of described hollow screw plug and steel ball is the conical surface.
The valve body that described spring is corresponding with the contact position of steel ball is provided with four equally distributed radial direction through hole.
The beneficial effect of the utility model is after having installed liquid discharging valve additional, and liquid discharging valve is not worked under normal exhaust pressure.Exhaust pressure can surpass rated discharge pressure when liquid, and liquid discharging valve was opened liquid and discharged from liquid discharging valve this moment, and exhaust pressure can be got back to normal value.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings:
Fig. 1 is the plan view of the utility model;
Fig. 2 is the enforcement illustration of the utility model.
Embodiment
As shown in Figure 1, a kind of compressor of the utility model is used liquid discharging valve, comprises valve body 1; Valve body 1 has step-like central through bore, and wherein the bigger end in aperture is a liquid feeding end, and wherein the less end in aperture is an outlet end; The outlet end of valve body 1 is provided with a flat mouthful of groove along diametric(al), is provided with screw thread at valve body 1 inner and outer surface of liquid feeding end, in valve body 1 central through bore near outlet end, has step surface; Step surface is the conical surface, and the conical surface is provided with pad 2, is provided with spring 3, steel ball 4, hollow screw plug 5 on the pad 2 successively; Described hollow screw plug 5 has central through bore; Said hollow screw plug 5 is connected with the interior threaded hole of valve body 1 end, and described spring 3, steel ball 4 are encapsulated in the step hole, and described hollow screw plug 5 is the conical surface with the contact jaw of steel ball 4; The valve body 1 that described spring 3 is corresponding with the contact position of steel ball 4 is provided with four equally distributed radial direction through hole, can be used for exhaust.
As shown in Figure 2; Liquid discharging valve 6 is connected with cylinder 7 through the outside thread of valve body, and under the normal condition, the power that spring 3 acts on the steel ball 4 acts on the power on the steel ball 4 greater than the pressure in the cylinder; Steel ball 4 is crushed on the sealing surface of hollow screw plug 5, and gas can't leak through steel ball 4.When the gas that gets into cylinder 7 contains liquid; Because of liquid can not be compressed; Pressure in the cylinder 7 rise, and the power that pressure acts on the steel ball of liquid discharging valve 6 acts on the power on the steel ball 4 greater than spring 3, and steel ball 4 leaves the sealing surface of hollow screw plug 5; The liquid outlet end is discharged from, thereby has guaranteed the Security of compressor.
Claims (5)
