Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spherical control valves, and particularly relates to a spherical control valve. Background Technique
[0002] A control valve, also known as a control valve, is the final control element in the field of industrial automation process control. By receiving the control signal output by the adjustment control unit, it changes process parameters such as the flow rate, pressure, temperature, and liquid level of the medium through power operation. Generally composed of an actuator and a valve. If classified according to the stroke characteristics, the control valve can be divided into linear stroke and angular stroke; according to the power used by the actuator it is equipped with, it can be divided into pneumatic control valves, electric control valves, and hydraulic control valves; according to its functions and characteristics, it can be divided into linear characteristics, equal percentage characteristics, and parabolic characteristics.
[0003] For the ball valve type control valve, its valve flap is a spherical body with a through hole, and it rotates 90° around the valve stem for flow regulation. Although the regulation curve of this type of valve can be designed by changing the shape of the through hole of the sphere, however, with the change of the channel shape (such as becoming a triangular cross-section channel), the flow capacity of the valve will decrease significantly. In addition, when in the regulation state, the fluid will also be deflected due to the guidance of the sphere channel, seriously scouring the valve body, and there is an urgent need for development. Content of the Utility Model
[0004] The purpose of the utility model is to provide a spherical control valve to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A spherical control valve includes a first valve body, a second valve body, a ball separator, and a flow control valve flap. One side of the first valve body is fixedly connected to the valve seat through installation and fastening parts. A ball separator is connected to one side of the valve seat, and a second valve body is connected to the other side of the valve seat. A fluid inlet channel and a valve cavity are formed inside the first valve body. A fluid discharge channel matching the fluid inlet channel is formed inside the second valve body. A number of flow-through holes are provided on the ball separator. A flow control valve flap is provided between the ball separator and the valve seat. An operating valve stem is connected inside the flow control valve flap, and the operating valve stem can control the rotation of the flow control valve flap to regulate the flow rate of the passing fluid;
[0006] The operating valve stem passes through the flow control valve flap, the ball separator, and the first valve body and extends outside the top of the first valve body.
[0007] Preferably, mounting frames are installed on the outer surfaces of the first valve body and the second valve body. Electric heating tubes are equidistantly arranged inside the mounting frames, and the electric heating tubes can dehumidify the outer surfaces of the first valve body and the second valve body.
[0008] Preferably, a positioning frame is fixed inside the fluid introduction channel. Water passing nets are connected to both sides of the positioning frame. A filter element is arranged inside the positioning frame, and the filter element is located between the two water passing nets.
[0009] Preferably, a partition plate is connected to the top of the filter element. A sealing gasket is arranged between the partition plate and the filter element. A lifting block is connected to the top of the partition plate. The setting of the sealing gasket can improve the sealing performance between the partition plate and the inner side wall of the positioning frame.
[0010] Preferably, a storage groove is connected to one side of the top of the positioning frame. A pressing member is hinged to the bottom inside the storage groove. The storage groove is used to completely store the pressing member to avoid affecting the operation of taking out the filter element.
[0011] Preferably, a return tension spring is hinged to the top surface of the pressing member, and the other end of the return tension spring is hinged to the inner surface of the storage groove.
[0012] Preferably, heat preservation cotton is embedded inside both the first valve body and the second valve body.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] (1) For this spherical control valve, by setting the ball separator communicated with the fluid discharge channel into a hemispherical structure, the axes of several fluid passing holes arranged on the ball separator all pass through the center of the ball inside the valve seat. In this way, when the streamline of the fluid passes through the fluid passing holes after being buffered in the valve cavity, it will converge towards the center of the ball, causing the fluids to collide with each other. This avoids the phenomenon that the fluid of an ordinary control valve directly impacts the valve body after flowing out through the ball separator and generates cavitation between it and the valve seat. This structure effectively protects the first valve body, the second valve body, the fluid introduction channel, the fluid discharge channel, and the valve seat, significantly increasing the overall service life of the control valve and reducing the generation of noise during the operation of the control valve.
[0015] (2) For this spherical control valve, through the setting and combined use of the water passing net and the filter element, the impurities in the fluid passing through the fluid introduction channel can be filtered, avoiding the phenomenon that harmful substances corrode or block the fluid introduction channel, the fluid passing holes, the valve cavity, and the fluid discharge channel. The expansibility of the return tension spring enables the pressing member to maintain a pressing force on the lifting block for a long time, enabling the filter element to be stably placed inside the positioning frame and facilitating the subsequent detachment of the filter element for cleaning or replacement.
[0016] (3) For this spherical control valve, through the setting of the electric heating tube, the areas around the first valve body and the second valve body can be dehumidified, which can avoid the corrosion of the outer surfaces of the first valve body and the second valve body. And through the combined setting of the heat preservation cotton, it is beneficial to the smooth flow of the liquid medium inside the fluid introduction channel, the valve cavity, and the fluid discharge channel in low-temperature and cold weather.

The ball separator 17 communicating with the fluid discharge channel 8 is arranged in a hemispherical structure. The axes of a plurality of flow-through holes 12 provided on the ball separator 17 all pass through the center of the ball in the valve seat 18. In this way, when the streamline of the fluid converges towards the center of the ball after passing through the buffer of the valve cavity 5 and passing through the flow-through holes 12, impacts are generated between the fluids, which avoids the phenomenon that the fluid of an ordinary regulating valve directly impacts the valve body after flowing out through the ball separator 17 and cavitation occurs in it and in the valve seat 18. This structure effectively protects the valve body 1, the valve body 9, the fluid inlet channel 14, the fluid discharge channel 8 and the valve seat 18, significantly increasing the overall service life of the regulating valve and reducing the generation of noise during the operation of the regulating valve;
[0025] The other side of the valve seat 18 is connected to a valve body 9. A fluid inlet channel 14 and a valve cavity 5 are formed inside the valve body 1. A fluid discharge channel 8 matching the fluid inlet channel 14 is formed inside the valve body 9. A plurality of flow-through holes 12 are provided on the ball separator 17.

[0026] Mounting frames 2 are installed on the outer surfaces of the valve body 1 and the valve body 9. Electric heating tubes 13 are equidistantly arranged inside the mounting frames 2. The arrangement of the electric heating tubes 13 can dehumidify the surroundings of the valve body 1 and the valve body 9, and can prevent the outer surfaces of the valve body 1 and the valve body 9 from being corroded.
[0027] A positioning frame 16 is fixed inside the fluid inlet channel 14. Water passing nets 3 are connected to both sides of the positioning frame 16.

The arrangement and cooperation of the water passing nets 3 and the filter element 15 can filter impurities in the fluid passing through the fluid inlet channel 14, avoiding the phenomenon that harmful substances corrode or block the fluid inlet channel 14, the flow-through holes 12, the valve cavity 5 and the fluid discharge channel 8.
[0028] A partition 10 is connected to the top of the filter element 15. A sealing gasket 11 is arranged between the partition 10 and the filter element 15. A lifting block 4 is connected to the top of the partition 10.
[0029] One side of the top of the positioning frame 16 is connected to a storage groove 1601. A pressing part 21 is hinged to the bottom inside the storage groove 1601.
[0030] A return tension spring 20 is hinged to the top surface of the pressing member 21, and the other end of the return tension spring 20 is hinged to the inner surface of the storage groove 1601. The expansibility of the return tension spring 20 enables the pressing member 21 to maintain a pressing force on the lifting block 4 for a long time, so that the filter element 15 can be stably placed in the positioning frame 16, and it is convenient to detach the filter element 15 for cleaning or replacement later.
[0031] Heat-insulating cotton 22 is embedded in the inner sides of both the valve body one 1 and the valve body two 9. Through the cooperative setting of the heat-insulating cotton 22, it is beneficial to the smooth flow of the liquid medium in the fluid introduction channel 14, the valve cavity 5, and the fluid discharge channel 8 in low-temperature and cold weather.
[0032] When the embodiment of the present application is in use: the water passing net 3 and the filter element 15 are provided and used in cooperation, which can filter the impurities in the fluid passing through the fluid introduction channel 14, and avoid the phenomena that harmful substances corrode or block the fluid introduction channel 14, the through-flow hole 12, the valve cavity 5, and the fluid discharge channel 8. The expansibility of the return tension spring 20 enables the pressing member 21 to maintain a pressing force on the lifting block 4 for a long time, so that the filter element 15 can be stably placed in the positioning frame 16, and it is convenient to detach the filter element 15 for cleaning or replacement later.
