具体实施方式Detailed ways

相关技术的旋塞阀使用过程中，燃气阀阀杆转到90°时为最大火状态，210°时为最小火状态，但从90°-210°的调节范围内，火力变化不够均匀，大火状态和小火状态占据调节范围广，过渡范围小，无法实现准确调节，从而影响烹饪效果。During the use of the plug valve in the related art, the gas valve stem is in the maximum fire state when it is turned to 90°, and it is in the minimum fire state when it is 210°. The low-fire state occupies a wide adjustment range, and the transition range is small, so accurate adjustment cannot be achieved, thereby affecting the cooking effect.

为此，本申请提出一种旋塞阀100，可以提升燃气阀流量调节性能，使流量线性变化，方便调整火力大小，满足烹饪过程中多种火力需求。For this reason, the present application proposes a cock valve 100, which can improve the flow regulation performance of the gas valve, make the flow change linearly, facilitate the adjustment of firepower, and meet various firepower requirements in the cooking process.

下面详细描述本申请的实施例，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。Embodiments of the present application are described in detail below, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout.

结合图1至图6和图7至图18，根据本申请实施例的旋塞阀100，包括：阀体1和阀芯2，阀体1具有阀腔108以及与阀腔108连通的进口101和出口102，气体可以从进口101进入阀体1从出口102排出。阀腔108内设有与出口102连通的第一通气口104和第二通气口106，使得阀腔108可以与出口102连通。阀芯2可转动地设于阀腔108内，阀芯2上设有与进口101连通的调节槽20，调节槽20与第一通气口104和第二通气口106沿阀芯2的周向相对。也就是说，阀芯2可以与进口101连通，调节槽20与阀体1的通气口相对，气体可以从进口101进入阀芯2，调节槽20与通气口相对时可以产生连通的空间，使气体可以进入阀腔108进入从出口102排出。Referring to FIGS. 1 to 6 and FIGS. 7 to 18 , the plug valve 100 according to the embodiment of the present application includes: a valve body 1 and a valve core 2 , the valve body 1 has a valve chamber 108 and an inlet 101 communicating with the valve chamber 108 and Outlet 102 , gas can enter the valve body 1 from the inlet 101 and be discharged from the outlet 102 . A first air port 104 and a second air port 106 communicating with the outlet 102 are provided in the valve chamber 108 , so that the valve chamber 108 can communicate with the outlet 102 . The valve core 2 is rotatably arranged in the valve cavity 108, and the valve core 2 is provided with an adjustment groove 20 communicating with the inlet 101. relatively. That is to say, the spool 2 can be communicated with the inlet 101, the regulating groove 20 is opposite to the air vent of the valve body 1, the gas can enter the spool 2 from the inlet 101, and a communicating space can be produced when the regulating groove 20 is opposite to the air vent, so that Gas can enter the valve chamber 108 and exit through the outlet 102 .

具体而言，阀芯2在阀腔108中转动可以改变阀芯2相对于阀腔108的位置，阀芯2具有第一位置和第三位置，阀芯2可以从在第一位置和第三位置之间转动，而在转动过程中，可以不断改变调节槽20与第一通气口104和第二通气口106的位置关系，从而改变通气量。阀芯2在第一位置时，调节槽20与第一通气口104完全接通并与第二通气口106错开，阀芯2在第三位置时，调节槽20与第一通气口104错开并与第二通气口106完全接通。Specifically, the rotation of the spool 2 in the valve cavity 108 can change the position of the spool 2 relative to the valve cavity 108, the spool 2 has a first position and a third position, and the spool 2 can change from the first position to the third position. Rotate between positions, and in the process of rotation, the positional relationship between the adjustment groove 20 and the first air vent 104 and the second air vent 106 can be constantly changed, thereby changing the air flow. When the spool 2 is in the first position, the regulating groove 20 is completely connected to the first vent 104 and staggered from the second vent 106; when the spool 2 is in the third position, the regulating groove 20 is staggered to the first vent 104 and staggered It is fully connected with the second vent 106 .

其中，本申请中所称调节槽20与通气口完全接通，是指在阀芯2转动过程中，调节槽20与该通气口之间具有最大的接通面积(或者称为最大开度)；调节槽20与通气口错开，是指在阀芯2转动过程中，调节槽20与该通气口之间不连通。举例而言，阀芯2在阀腔108内转动的过程中，当阀芯2处于第一位置时，调节槽20与第一通气口104之间的接通面积最大，而调节槽20与第二通气口106不接通。当然，在阀芯2在阀腔108内转动的过程中，阀芯2可以具有多个位置能够使调节槽20与第一通气口104之间维持最大的接通面积；阀芯2也可以具有多个位置能够使调节槽20与第一通气口104不接通。其中，调节槽20与通气口(通气口可以为第一通气口104或第二通气口106)完全接通，接通面积最大，通气量大；调节槽20与通气口错开或者部分接通时，接通面积较小，通气量较小；调节槽20与通气口错开时，调节槽20与通气口不接通，通气量最小(不通气)。Wherein, in this application, the adjustment groove 20 is completely connected with the ventilation port, which means that during the rotation of the valve core 2, there is the largest connecting area (or the maximum opening) between the adjustment groove 20 and the ventilation port. Staggering between the adjustment groove 20 and the ventilation port means that during the rotation of the valve core 2, there is no communication between the adjustment groove 20 and the ventilation port. For example, during the rotation of the valve core 2 in the valve cavity 108, when the valve core 2 is in the first position, the connection area between the adjustment groove 20 and the first air port 104 is the largest, and the adjustment groove 20 and the first air port 104 are the largest. The second air port 106 is not connected. Of course, during the rotation of the spool 2 in the valve chamber 108, the spool 2 can have a plurality of positions to maintain the maximum connection area between the adjustment groove 20 and the first vent 104; the spool 2 can also have Multiple positions enable the adjustment slot 20 to be disconnected from the first vent 104 . Wherein, the regulating groove 20 is fully connected with the vent (the vent can be the first vent 104 or the second vent 106), the connection area is the largest, and the ventilation volume is large; when the regulating groove 20 is staggered or partially connected with the vent , the connection area is small, and the ventilation volume is small; when the adjustment groove 20 is staggered with the ventilation opening, the adjustment groove 20 is not connected with the ventilation opening, and the ventilation volume is minimum (no ventilation).

进一步地，阀芯2从第一位置到第三位置调节槽20与第一通气口104和第二通气口106的总接通面积逐渐减小。换言之，阀芯2从第一位置到第三位置的调节过程中，通气量逐渐减小，当旋塞阀100应用于燃气阀中时，将阀芯2从第一位置转动到第三位置的过程中，阀芯2与阀腔108之间的接通面积逐渐减小，燃气流量逐渐减小，使得火力可以逐渐由大到小发生变化，便于用户进行火力调节，提升烹饪效果。也可也是，在第一位置到第三位置的过程中，总接通面积逐渐减小。调节槽20与第一通气口104完全接通的面积小于与第二通气口106完全接通的面积。其中，在阀芯2从第一位置到第三位置转动的过程中，存在调节槽20与第一通气口104的接通面积逐渐减小、调节槽20与第二通气口106的接通面积逐渐增大的过程，而且在这一过程中总接通面积逐渐减小，因此，阀芯2在从第一位置转动到第三位置时，阀芯与出口之间的接通面积的变化较为平缓，能够实现阀芯与出口之间接通面积较为精确地调节，避免阀芯与出口之间的接通面积突然增大或突然减小。Further, the total communication area of the valve core 2 from the first position to the third position between the adjustment groove 20 and the first vent port 104 and the second vent port 106 decreases gradually. In other words, during the adjustment process of the spool 2 from the first position to the third position, the ventilation volume gradually decreases. When the plug valve 100 is applied to a gas valve, the process of turning the spool 2 from the first position to the third position , the connection area between the valve core 2 and the valve cavity 108 gradually decreases, and the gas flow rate gradually decreases, so that the firepower can gradually change from large to small, which is convenient for users to adjust the firepower and improve the cooking effect. It is also possible that the total contact area gradually decreases in the process from the first position to the third position. The area of the adjustment slot 20 completely connected to the first vent 104 is smaller than the area completely connected to the second vent 106 . Wherein, during the rotation of the spool 2 from the first position to the third position, the connection area between the adjustment groove 20 and the first air port 104 gradually decreases, and the connection area between the adjustment groove 20 and the second air port 106 gradually decreases. The process of gradually increasing, and in this process the total connection area gradually decreases, therefore, when the valve core 2 rotates from the first position to the third position, the change of the connection area between the valve core and the outlet is relatively small. Gently, it can realize more precise adjustment of the connection area between the valve core and the outlet, and avoid the sudden increase or decrease of the connection area between the valve core and the outlet.

根据本申请实施例的旋塞阀100，通过逐渐改变阀芯2调节槽20与阀腔108通气口之间的总接通面积，从而改变通气量，进而增大中间火力的调节范围和调节准确性。According to the plug valve 100 of the embodiment of the present application, by gradually changing the total connection area between the adjustment groove 20 of the valve core 2 and the vent port of the valve cavity 108, the ventilation volume is changed, thereby increasing the adjustment range and accuracy of the intermediate firepower .

需要说明的是，总接通面积是指调节槽20与第一通气口104的接通面积、调节槽20与第二通气口106的接通面积之和。例如当第一通气口104和第二通气口106均与调节槽20的一部分连通，总接通面积为调节槽20与第一通气口104的接通面积和调节槽20与第二通气口106的接通面积之和；当第一通气口104和第二通气口106中的一个通气口与调节槽20接通，而第一通气口104和第二通气口106中的另一个通气口与调节槽20不接通时，总接通面积可以为与通气槽20接通的那个通气口与通气槽20的接通面积。It should be noted that the total connection area refers to the sum of the connection area between the adjustment slot 20 and the first vent 104 and the connection area between the adjustment slot 20 and the second vent 106 . For example, when the first air port 104 and the second air port 106 are all communicated with a part of the regulating groove 20, the total connection area is the connecting area of the regulating groove 20 and the first air port 104 and the connecting area of the regulating groove 20 and the second air port 106 The sum of the connected areas; when one of the first vent 104 and the second vent 106 is connected to the regulating groove 20, and the other vent in the first vent 104 and the second vent 106 is connected to the When the regulating groove 20 is not connected, the total connection area may be the connection area between the vent opening connected with the ventilation groove 20 and the ventilation groove 20 .

实际使用时，以旋塞阀100应用于燃气灶为例，通过在第一位置和第三位置之间转动阀芯2，可以改变火力大小，即从最大火调节至中火或中小火，或者从最小或调节至最大火等，利于提高中间火力的准确性，为用户调节提供便利。In actual use, taking the cock valve 100 applied to a gas cooker as an example, by turning the valve core 2 between the first position and the third position, the firepower can be changed, that is, from the maximum fire to medium fire or medium fire, or from The minimum or maximum fire, etc., will help improve the accuracy of the intermediate firepower and provide convenience for users to adjust.

结合图7至图12，可选地，阀芯2从第一位置向第三位置转动时调节槽20与第一通气口104的接通面积逐渐减小，且阀芯2从第一位置向第三位置转动预定角度后调节槽20与第二通气口106接通。具体地，从前面的描述可以看出，调节槽20与第一通气口104完全接通时的总接通面积，大于调节槽20与第二通气口106完全接通时的总通流面积，因此，阀芯2从第一位置转动预定角度之后，总接通面积依然大于第三位置的总接通面积，但是此时的总接通面积与第三位置的总接通面积的差值减小(相对于第一位置和第三位置的总接通面积之差)，因此，在阀芯2从第一位置转动预定角度后再转动至第三位置的过程中，总接通面积的变化减小，从而可以使阀芯2在转动过程中总接通面积能够较为平滑地变化，避免了阀芯2在转动较小的角度时总接通面积的变化却非常大的问题，从而提供了线性度更高的调节方式。在第一位置和第三位置之间形成过渡段，可以缩小燃气灶大火状态和小火状态占据的调节范围，利于增大过渡范围，实现准确调节火力的效果。7 to 12, optionally, when the spool 2 rotates from the first position to the third position, the connection area between the adjustment groove 20 and the first vent 104 gradually decreases, and the spool 2 moves from the first position to the third position. After the third position is rotated by a predetermined angle, the adjustment slot 20 is connected to the second vent 106 . Specifically, it can be seen from the foregoing description that the total connection area when the regulating groove 20 is completely connected with the first vent 104 is greater than the total flow area when the regulating groove 20 is completely connected with the second vent 106, Therefore, after the spool 2 rotates a predetermined angle from the first position, the total connection area is still larger than the total connection area at the third position, but the difference between the total connection area at this time and the total connection area at the third position is reduced. Small (relative to the difference between the total connection area of the first position and the third position), therefore, when the spool 2 rotates from the first position to a predetermined angle and then rotates to the third position, the change of the total connection area reduced, so that the total connection area of the spool 2 can change smoothly during the rotation process, avoiding the problem that the total connection area of the spool 2 changes very large when the spool 2 rotates at a small angle, thus providing A more linear adjustment method. Forming a transition section between the first position and the third position can reduce the adjustment range occupied by the high fire state and the low fire state of the gas stove, which is beneficial to increase the transition range and realize the effect of accurately adjusting the firepower.

结合图9，可选地，阀芯2还具有第二位置，第二位置位于第一位置和第三位置之间，即阀芯2在第二位置时，调节槽20与通气口的总接通面积值小于第一位置且大于第三位置。阀芯2在从第二位置到第三位置转动时调节槽20与第二通气口106完全接通、且调节槽 20与第一通气口104的接通面积逐渐减小。换言之，从第二位置到第三位置时，总接通面积逐渐减少，主要是由于调节槽20与第一通气口104的接通面积的逐渐减小。也就是说，此时调节槽20与第二通气口106之间的接通面积没有发生变化，而调节槽20与第一通气口104之间的接通面积逐渐减小，这样阀芯2的旋转过程中仅仅会改变调节槽20与第一通气口104的接通面积，从而可以便于实现调节槽20与第一通气口104之间接通面积的平滑调节，增加总接通面积(或者说通气量)调节过程的线性度。9, optionally, the valve core 2 also has a second position, the second position is located between the first position and the third position, that is, when the valve core 2 is in the second position, the total connection between the adjustment groove 20 and the vent port The pass area value is smaller than the first location and larger than the third location. When the spool 2 rotates from the second position to the third position, the regulating groove 20 is fully connected with the second vent 106, and the connection area between the regulating groove 20 and the first vent 104 gradually decreases. In other words, when going from the second position to the third position, the total connection area decreases gradually, mainly due to the gradual reduction of the connection area between the adjustment slot 20 and the first vent 104 . That is to say, at this time, the connection area between the adjustment groove 20 and the second air port 106 does not change, while the connection area between the adjustment groove 20 and the first air port 104 gradually decreases, so that the valve core 2 During the rotation, only the connecting area between the adjusting groove 20 and the first air vent 104 will be changed, so that the smooth adjustment of the connecting area between the adjusting groove 20 and the first air vent 104 can be easily realized, and the total connecting area (or ventilation) can be increased. amount) to adjust the linearity of the process.

具体而言，结合前述，阀芯2在第一位置时第一槽部201与第一通气口104完全接通，此时阀芯2与阀腔108的总接通面积最大，燃气流量最大，燃气灶表现为大火状态。阀芯2在第三位置第二槽部202与第二通气口106完全接通，此时，阀芯2与阀腔108的总接通面积最小，燃气流量最小，燃气灶表现为小火状态。另外，在阀芯2转动的过程中，第一槽部201仅能接通第一通气口104沿阀芯2的周向相对的部分，而第二槽部202可以接通第一通气口104的靠近第二通气口106的部分以及第二通气口106，这样能够方便实现阀芯2在第一位置、第三位置(以及第二位置)之间的调节，以便于满足前述提高线性度的要求。Specifically, in combination with the foregoing, when the valve core 2 is in the first position, the first groove portion 201 is completely connected to the first air port 104.

In addition, during the rotation of the valve core 2, the first groove 201 can only connect to the opposite part of the first vent 104 along the circumferential direction of the valve core 2, while the second groove 202 can connect to the first vent 104.
