Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, the present invention provides a stop valve 10 and a valve cartridge 200 thereof. The shutoff valve 10 includes a valve body 100 and a valve body 200.
The valve body 100 has a hollow structure, and has an inlet 101, an outlet 102, and a fluid passage 103 connecting the inlet 101 and the outlet 102. The valve body 100 is generally integrally formed of a metal material such as brass, stainless steel, or the like. Wherein a valve port 104 is provided in the fluid passage 103. The valve cartridge 200 is slidably mounted in the valve body 100. The valve port 104 is adapted to cooperate with the valve body 200 to open and close the fluid passage 103.
The valve body 100 may take a variety of shapes. Specifically, in the embodiment, the valve body 100 includes a first tube 110 and two second tubes 120 located at two opposite sides of the first tube 110, perpendicular to the first tube 110, and communicating with the first tube 110. Thus, the valve body 100 has a "cross shape".
The valve cartridge 200 is installed in one of the second bodies 120, and the fluid passage 103 is formed in the first body 110 and the other second body 120. Specifically, the fluid passage 103 is L-shaped, and the valve port 104 is a corner of the fluid passage 103. In this case, the valve body 200 and the fluid passage 103 are not aligned with each other, so that the shutoff valve 100 can be more compact.
In order to ensure the mechanical strength of the valve body 100, further, in the present embodiment, the first tube 110 and the second tube 120 are integrally formed.
Referring to fig. 3, the valve element 200 includes a body 210 having a cylindrical structure, a sealing surface 220 is formed at one end of the body 210, and an operation hole 230 is opened at an end surface of the other end. Wherein the sealing surface 220 may extend into the valve port 104 and contact an edge of the valve port 104 to close the fluid channel 103. The valve cartridge 200 can be operated by inserting the operation tool 20 into the operation hole 230.
Specifically, in the present embodiment, the operation hole 230 is an inner hexagonal screw hole. That is, the operation hole 230 has a hexagonal cross-section. Accordingly, the valve cartridge 200 can be operated by a general hexagonal wrench.
Further, the operation hole 230 includes a plurality of hole sections sequentially communicating along a central axis of the operation hole 230, and the hole diameters of the plurality of hole sections sequentially increase in a direction from the bottom of the operation hole 230 to the opening of the operation hole 230. That is, the operation hole 230 is a stepped hole, and is divided into a plurality of sections, and the hole diameter of each section is different.
When the valve core 200 needs to be operated, an operation tool 20 (such as a hexagon wrench) can extend into the operation hole 230 from the opening. When the outer diameter of the working tool 20 is smaller than the inner diameter of the bore section near the opening, the working tool 20 may continue to extend inwards until the bore section adapted to the bore diameter comes into engagement. That is, the operation hole 230 of the valve body 200 can be adapted to a plurality of different types of operation tools 20, so that when the stop valve 10 is operated, it is no longer limited to use a specific type of operation tool 20, thereby facilitating the operation.
As shown in fig. 1 and 2, the operation hole 230 includes two hole segments, i.e., a first hole segment 231 and a second hole segment 233. Wherein the first pore section 231 has a larger pore size than the second pore section. When a wrench with a larger outer diameter is used for operation, the wrench can be clamped with the first hole section 231 (shown in fig. 1); when using a wrench with a smaller outer diameter, the wrench can pass through the first hole segment 231 until it is engaged with the second hole segment 233 (shown in FIG. 2). Thus, access opening 230 can accommodate two different models of wrenches.
In the present embodiment, the lengths of the plurality of hole segments increase in order in the direction from the bottom of the operation hole 230 to the opening of the operation hole 230.
That is, the closer to the bottom of the manipulation hole 230, the smaller the length of the hole segment, and the closer to the opening of the manipulation hole 230, the larger the length of the hole segment. The length of the hole segment refers to the size of the hole segment in the circumferential direction of the operation hole 230. Specifically, the closer to the opening of the operation hole 230, the larger the hole diameter of the hole section. Therefore, when the depth of the operation tool 20 inserted into the operation hole 230 is small, the operation tool 20 can be prevented from being easily detached from the operation hole 230 by increasing the contact area with the inner wall of the hole section.
In the present embodiment, the central axis of the operation hole 230 overlaps the central axis of the body 210. That is, the position of the operation hole 230 is located at the center of the body 210. Therefore, when the operating tool 20 is inserted into the operating hole 230 to operate the valve cartridge 200, the main body 210 is more evenly stressed, which is more advantageous for operation.
In the present embodiment, the sidewall of the body 210 is formed with two protrusions 211 extending in the circumferential direction of the body 210, and the two protrusions 211 are spaced apart in the axial direction of the body 210 to form the seal groove 213.
Specifically, the seal groove 213 is used to receive and fix the seal ring 300, thereby enhancing the sealing performance between the body 210 and the valve body 100.
When the valve body 200 is to be operated, the operation tool 20 may be inserted into the operation hole 230 from the end surface of the body in the shutoff valve 10 and the valve body 200. Further, since the operation hole 230 has a plurality of hole sections, the hole diameters of the plurality of hole sections increase in order from the bottom to the opening. Thus, a variety of different outer diameters of working tools 20 may be inserted through the opening of working bore 230 and form fits with the bore section having the appropriate bore diameter. That is, the operation hole 230 of the valve body 200 can be adapted to a plurality of different types of operation tools 20, so that when the stop valve 10 is operated, it is no longer limited to use a specific type of operation tool 20, thereby facilitating the operation.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
