Description

Actuator Mounting Bracket for Valve {BRACKET FOR VALVE}

The present invention relates to an actuator mounting bracket for a valve, and more particularly, to a mounting bracket improved by mounting an actuator to a valve while preventing the high temperature and high heat generated from the valve from being transmitted to the actuator.

Various types of valves used for controlling the flow of fluids have been developed and used. Among them, butterfly valves are frequently used due to their ability to appropriately control the flow rate of fluids. Looking at the configuration of the butterfly valve used for the purpose of controlling the flow rate of FIG. 1 as follows.

Conventional fluid control valve 100 has a valve body 102 having a flow path hole 101 so that the fluid can flow in the center, the flow path 101 can control the flow rate by opening and closing The disk 103 is connected with the stem 104 which is rotatably operated by the operating means.

The disc 103 and the valve body 102 are intermittent to the seat retainer 106 via the valve seat 105 as a means for maintaining airtightness, and the bottom of the stem 104 is airtight for airtightness. Finish with cover 108 via the ash 107.

The stem bearing 109 may be interposed between the stem 104 and the valve body 102 so as to ensure smooth operation of the stem 104 on the upper side of the stem 104. After closing the packing 110 so as to end with a packing gland (Packing Gland, 111).

It is configured by mounting the actuator 113 to the mounting flange 112 provided on the valve body 102 to open and close the disk 103 by mechanically operating the stem (104).

In general, since the fastening holes formed in the mounting flange and the actuator do not coincide and the positions of the fastening holes vary depending on the valves, the mounting holes are fastened through the mounting bracket between the mounting flange and the actuator.

Conventionally, such a mounting bracket 1 has been used, which will be described below with reference to FIG. 7.

It is provided with a bracket body (2) to have a predetermined height by performing a flat state or bending, such as a non-ferrous metal material such as ferrous metal or aluminum, each of the bottom surface 3 and the upper surface (4) of the bracket body (2) After forming the fastening hole 5 having the same PCB as the fastening hole formed in the valve and the actuator, the fastening means 6 such as a bolt or the like is firmly fixed to the valve 7 and the actuator 8.

In the prior art as described above, although the material of the bracket is non-ferrous metal, it is required to go through various processes (processes) because it is formed after bending holes are formed in the plate-shaped member made of ferrous metal so as to cope with the durability generated during the operation after mounting. Therefore, not only is the productivity poor, but also acts as a cause of the increase in the production cost.

Although the fluid passing through the valve has a low temperature or room temperature, most of them control the fluid of high temperature and high pressure. Therefore, the high temperature fluid is transferred to the actuator through the valve body in the process of being controlled by the valve, and the operation control inside the actuator is performed. Will affect electrical or electronic components for

Thus, when high temperature is not instantaneously conducted through the valve to the electric or electronic product provided inside the actuator, and is conducted for a long time from the beginning to the end of controlling the fluid, the electrical or electronic component that is vulnerable to heat (high temperature) is damaged or It will cause an inoperable state.

Since the heat conduction is not high at the initial stage when the valve is operated, the valve can be easily opened and closed by the actuator without excessive force, but as time passes, the high temperature is conducted to the actuator through the valve body and the bracket, and thus the fine operation abnormality occurs. Since the disk to be controlled is not controlled, various problems occur such that the flow of the fluid is not normally controlled and thus adversely affects the post-valve process.

In the present invention, a valve body having a flow path to flow the fluid as invented to solve the above problems, and a stem connected to the disk coupled to the rotational operation to control the flow rate in the flow path and And a seat retainer intermittently interposed between the disc and the valve body via a valve seat, a cover finishing through an airtight material for airtightness at the bottom of the stem, and a stem bearing and packing on the upper side of the stem. The valve is configured to mechanically operate the stem by mounting the actuator via a mounting bracket provided on the packing gland and a mounting flange provided on the upper portion of the valve body. The mounting bracket is made of a non-metal material having low thermal conductivity. Injection molding to form a bracket body, the stem of the valve in the center of the bracket body Including a stem hole to be formed so that, and the bottom surface of the bracket body in close contact with the mounting flange and the upper surface in close contact with the actuator includes a fastening hole formed in the mounting flange and the actuator and fastening means to be fastened by the means, The high temperature and high heat conducted from the fluid flowing through the valve can be prevented from being transmitted to the actuator, thereby ensuring the smooth operation of the actuator and the valve.

The present invention improves the mounting bracket that assists the mounting of the actuator by correcting the PC (PCD) of the fastening hole formed in the valve and the actuator to provide ease of mounting, as well as the high temperature, high heat from the valve through the mounting bracket It is an invention having various effects such as to prevent the conduction of the valve to ensure the smooth operability of the actuator to increase the quality of the entire valve.
