Description

[Detailed description of the invention] Industrial application field This invention relates to a mounting seat plate in a valve body.

This idea is useful for multi-purpose applications such as opening and closing the flow action of pressurized fluid and switching the flow direction, and also for fixing or fixing the valve body to a desired location in a valve body with multiple connection ports protruding in multiple directions. This relates to a mounting seat plate for a valve body.

Conventional technology The mounting seat plate of a conventional valve body is constructed as part of the valve body at the same time as forging, and screw holes are drilled in a separate drilling process at the set positions of the overhanging mounting seat plate parts. was formed.

Problems to be Solved by the Invention As mentioned above, the mounting seat plate part in the valve body is formed by forging at the same time as forming the valve body outer body, and then at least two screw holes are formed at desired positions. These screw holes are drilled in a drilling process, and when manufacturing these screw holes, the screw holes are customarily drilled in general-purpose locations without considering the condition when the valve body is installed and used. .

Therefore, when the valve body is installed, the position of the device is forcibly determined based on the screw holes already drilled in the mounting seat plate of the valve body, and in some cases, the position of the device is determined partially at the planned installation location of the valve body. In some cases, it may even be impossible to install due to the screw holes that are required. This simply means that the screw holes are already installed and cannot be moved relative to the valve body.

The mounting seat plate of the valve body of this invention has screw engagement grooves oriented toward the center of the valve body from both ends that project approximately in the shape of wings in the left and right horizontal directions. By engaging the mounting screw in an arbitrary location with an elongated groove that corresponds to the location of the valve body, the conditions for the mounting position and screw locking situation are relaxed, and the valve body can be installed in tandem. In this case, the ends of the mounting seat plates of adjacent valve bodies are aligned, and an open-type screw engagement groove is formed in the joint portion so that the mounting plate can be mounted with a single screw. The engagement groove is formed together with the mounting seat plate when the valve outer body is forged.

Embodiment Next, an embodiment of this invention will be described with reference to the drawings. Reference numeral 1 denotes a valve body, and a plurality of protrusions 2 are formed on the main portion of the valve body 1 from its surface. The protrusion 2 indicates an inlet/outlet such as a fluid introduction path or a fluid discharge path, a connection port of a fluid introduction pipe, and a valve operation part of a valve body (not shown) disposed in the valve body 1. So, since this idea is not related to the internal structure of the valve body,
A description of the related structure between the protrusion 2 and the valve body will be omitted.

one protrusion 2' among the plurality of protrusions 2;
To explain this in more detail, from the connection part between the protrusion 2' on the extension line of the lower end of the vertical valve body 1 and the lower main end of the valve body 1, on a line perpendicular to the vertical line, that is, in both left and right directions, In addition, the mounting seat plates 3, 3 are formed to protrude in a substantially wing shape in the horizontal direction, and screw engagement grooves 4 that open at the tip sides 31, 31 of both the mounting seat plates 3, 3 are formed in the mounting seat plates 3, 3. The base of No. 3 is oriented and recessed. The groove width dimension of this screw engagement groove 4 should be larger than the thread diameter of the screw 5 used for mounting and fixing the valve body 1, and smaller than the head diameter thereof.

As an embodiment of the groove width dimension of the screw engaging groove 4 described above, a mounting seat plate 3 in which the screw engaging groove 4 is recessed is provided.
The length of the tip sides 3, 3 is divided into three equal parts, the dimension of the divided part at the center position is the groove width dimension of the screw engagement groove 4, and the grooves located on both sides forming the screw engagement groove 4 are The width of each of the edge protrusions 32, 32 is also the same as the groove width of the screw engagement groove 4, and therefore, when a plurality of valve bodies 1 are installed in tandem, the mounting seats of the valve bodies 1 installed adjacent to each other are the same. A mounting seat plate 3 in which one piece of groove edge protrusion 32 is adjacent to each other in one direction on the plate 3
The screws can be inserted into the screw engagement grooves 4 of the screws 3 and 3, thereby allowing both mounting seat plates 3 to form an engaged state with each other.

In another embodiment, in either one of the mounting seat plates 3 that protrude in both left and right directions of one valve body 1, the screw engaging groove extends from the tip side 31 to the terminal position of the screw engaging groove 4. These mounting seat plates are formed by cutting out 1/2 of the thickness of the mounting seat plate 3 above or below in the groove edge protrusions 32 located on both sides forming the mounting seat plate 4 to form an overlapping stepped portion 33. In No. 3, the mode in which two valve bodies 1 are installed adjacently in tandem is particularly effective when installing the valve bodies 1 in an air conditioning circuit of a cooler.

In this way, when the mounting seat plates 3, 3 having the screw engaging grooves 4, 4 are forged and formed into the outer body part of the valve body 1, the screw engaging grooves 4, 4 are also formed in a concave form at the same time. It is.

Function This device is constructed as described above, and the valve body 1 is installed in the set mounting position for the device in which it is to be used.If one valve body 1 is used, two screws are required. 5 to engage with each of the screw engagement grooves 4, 4 and fix the valve body 1 to the mounting board. But that's fine.

In addition, when the valve bodies 1 are to be arranged in tandem, the front end sides 31 of the mounting seat plates 3, 3 of each one of the valve bodies 1, 1 to be arranged adjacent to each other,
31, and both screw engagement grooves 4, 4 are aligned on a line, and the joined tip sides 31,
Both mounting seat plates 3, 3 can be fixed to the board by pressure using one screw 5 at a position perpendicular to the internal extension line of 31 and the longitudinal center line of the screw engaging grooves 4, 4. .

Further, in the embodiment described above, when one groove edge protrusion 32 and the groove width of the screw engagement groove 4 have the same dimension, only one of them can be inserted at a place where the meshing relationship is formed by meshing with each other. By inserting the screw 5 into the engagement tip at the innermost end of the screw engagement groove 4, both groove edge protrusions 32 can be pressed and fixed.

Furthermore, in embodiments other than the above, the mounting seat plate 3 of the valve body 1 to be installed adjacently is overlapped, and the upper and lower notches of the stepped portion 33 are overlapped to form the thickness of one piece of the mounting seat plate 3. By inserting one screw 5 into the long screw engagement groove 4, the overlapping portions of both mounting seat plates 3 can be fixed by pressure.

In principle, two screws 5 are required when attaching and fixing one valve body 1 to one valve body 1 in this way, but when installing multiple valve bodies 1 in tandem, the above If appropriate mounting means are provided, it is also possible to mount the valve body using one more screw 5 than the number of valve bodies 1 used.

Effects As described above, in this invention, the outer body of the valve body 1 and the mounting seat plates 3, 3 are integrally molded, and the molded body has a forged structure, and the mounting seat plates 3, 3 are provided with recesses. Since the screw engaging grooves 4, 4 are opened at the tip sides 31, 31 of the mounting seat plates 3, 3, these screw engaging grooves 4, 4 can also be formed at the same time during the forging construction, and can be replaced with the conventional screw engaging grooves 4, 4. Compared to drilling operations that require a separate drilling operation, at least two steps can be shortened.

In addition, when the valve body 1 is installed, the screw engagement position can be avoided due to the length of the screw engagement groove 4, and the valve body 1 can be installed while avoiding an inconvenient location.
When installing multiple parts in tandem, normally two screws 5 are used to attach and fix the valve body 1, but it is possible to attach and fix it with one more screw 5 than the number of valve bodies 1 used. Therefore, together with the effect of reducing the number of screws 5 used, it is possible to improve workability and reduce the installation area in the case of interlocking arrangement or overlapping arrangement, and therefore, the valve body 1 This is characterized by the fact that the overall configuration of the device in which it is installed can be made smaller.
