Description

[Detailed description of the invention] (Field of industrial application) This invention is a mount for mounting a valve on a stand, or for firmly mounting a heavy object such as an actuator for automatic operation without adding weight to the valve. Regarding equipment.

(Prior Art) As a synthetic resin mounting device for holding and attaching a synthetic resin ball valve to a stand and an actuator for automatic operation, there is one described, for example, in US Pat. No. 3,533,142.

This mount device consists of a pair of half-ring-shaped mount bodies that have the same shape, and a T-shaped mount body on both sides.
It includes two bands forming a letter shape and two wedge members. Then, by placing a ball valve between the mount bodies, passing a band between both sides of the mount bodies, and fixing the band to the mount body with a wedge member,
The ball valve is supported, and the mounting portion provided at the center of each mount body is adapted to be mounted to a frame and an actuator, respectively.

(Problem to be solved by the invention) However, since the above device requires a band and a wedge member in addition to the mount body,
It takes time to connect the mount bodies,
Moreover, when connecting a pair of mount bodies, it is difficult to accurately position the mount bodies, and if the positions are deviated, it is impossible to attach the band. Furthermore, since the band is made of synthetic resin, it also has the disadvantage of slipping off when worn. Furthermore, the number of parts is large, and
Since many molds are required for injection molding these parts, manufacturing costs are high. Furthermore, in the above device, tensile force is applied to the elongated member such as the T-shaped band, and depending on the usage conditions, the connection between the mount bodies may be released due to vibration, creep, fatigue, etc. .

Further, Japanese Utility Model Application No. 60-152876 discloses a pair of half-ring-shaped mount bodies having the same shape, and a shoulder portion having a through hole for bolt insertion is formed on both sides of each mount body. By providing a tongue piece having an engagement hole on one side, providing a protrusion on the other side, providing a mounting portion in the center, and connecting the mount bodies by engaging the protrusion with the engagement hole, A mounting device for holding the valve is described.

However, in the case of this mount device, there are tongues and protrusions that engage with each other, so connecting the mount bodies is easy, but it is not necessary to replace the valve itself or replace the valve parts (such as the seal ring) with new ones. On the other hand, the drawback was that it was difficult to remove the mount bodies from each other when replacing them. In addition, with this device, the mount bodies can be connected to each other without using bolts or nuts, but after they are connected, external shocks, such as piping jigs, etc. may hit the connecting parts and damage them. In this case, the connection will be broken. However, when reconnecting using bolts and nuts, it becomes difficult to align the upper and lower mount bodies because the tongues that were originally there are not present.

Furthermore, when installing the valve on a pedestal, it may be difficult to attach the valve to the pedestal depending on the type of valve. That is, the working space between the outer surface of the valve and the lower part of the mount body becomes narrower, and the work of passing screws through the through holes of the attachment part in the lower part of the mount body becomes complicated and time-consuming.

The present invention solves the drawbacks of the conventional mounting device described above.The purpose of this invention is to reduce the number of parts, reduce manufacturing cost, and simplify the process of connecting the mount bodies to each other. Even if the valve is slightly misaligned, the valve mount device can be accurately clamped while correcting the position shift during the bolt/nut connection work, and it is also easy to install the mount device to the mount. It is to provide.

(Means for Solving the Problems) The gist of the present invention is to provide a valve between a pair of mount bodies having a recess for supporting the valve in the center and through holes for inserting bolts on both sides. In a valve mount device that clamps a valve by connecting the mount bodies with bolts and nuts in a state in which the mount bodies are arranged, the mount bodies are fitted to the circumferential edges of the top surfaces of both sides of the pair of mount bodies that face each other and come into contact with each other. A matching groove or protrusion is provided, and
A valve mount device is characterized in that insert nuts for mounting a pedestal are embedded in the bottom of both sides of a mount body.

(Function) As mentioned above, since grooves or protrusions that fit into each other are provided on the periphery of the upper surface of both sides of the mount body, when connecting the mount bodies,
Even if the mount bodies are slightly misaligned, it can be corrected by connecting them with bolts and nuts and fitting the protrusions into the grooves.

Further, the groove and the protrusion simply fit together, and the valve and valve parts can be replaced and replaced easily.

Furthermore, the mounting device can be easily attached to the frame by using the insert nuts buried in the bottoms of both sides of the mount body.
