Description

Integral flange corrugated pipe gate valve body forging

Technical Field

The utility model relates to a valve component, in particular to a valve body forging of an integral flange corrugated pipe gate valve.

Background

The opening and closing part of the gate valve is a gate plate, the moving direction of the gate plate is vertical to the fluid direction, and the gate valve can only be fully opened and fully closed and cannot be adjusted and throttled. Gate valves are sealed by the contact of the valve seat and the gate plate, and the sealing surface is usually bead-welded with a metallic material to increase wear resistance. Gate valves are classified into rigid gate valves and elastic gate valves according to differences in gate plates.

The valve has wide application field, different use requirements on the valve in different fields, and the valve which only can control the fluid medium cannot meet the use requirements of the existing market. In order to meet the development requirements of the market, a series of valves capable of detecting the temperature of the fluid medium, sampling and the like are available on the market. The existing valve capable of sampling has a complex sampling structure, so that the production cost is high; the temperature sensors are required to be arranged on each valve, so that the production cost of the valves is increased to a certain extent, and once the existing temperature sensors break down, the temperature sensors are difficult to repair or replace, and the later maintenance cost of the valves is also increased.

SUMMERY OF THE UTILITY MODEL

The technical purpose of the utility model is realized by the following technical scheme: the utility model provides an integral flange bellows gate valve body forging, includes the valve body, the valve body includes the inflow pipe and the play flow pipe of main part and connection main part, be formed with into the inflow pipe and go out the flow in, be formed with out the runner in the play flow pipe, install the shielded box that has the isolation chamber in the inflow pipe, be formed with the opening that the chamber was kept apart in the intercommunication and the inflow pipe on the shielded box, be equipped with the external operation mouth with keep apart the chamber of intercommunication on the inflow pipe, demountable installation has the sealing member on the operation mouth, be equipped with the closing cap on the opening, the inflow pipe is equipped with the control assembly who is used for controlling the closing cap and opens and close outward.

Through adopting above-mentioned technical scheme, control assembly control closing cap is opened the opening, and fluid medium gets into through the opening and keeps apart the chamber, and rethread control assembly control closing cap is sealed with the opening, makes fluid medium detain in keeping apart the intracavity. And finally, the operation port is opened through the sealing piece, so that a worker can sample the fluid medium in the isolation cavity, and the temperature measurement operation on the fluid medium can be realized by inserting the thermometer into the isolation cavity. This kind of simple structure just need not to be equipped with temperature sensor on every valve, can realize temperature measurement and sample function simultaneously, has reduced the manufacturing cost of enterprise.

Further setting the following steps: the control assembly comprises a control rod in sealing sliding fit with the inflow pipe and a connecting rod for connecting the control rod and the sealing cover, the sealing cover is hinged to the inflow channel wall or the isolation box through a hinge, and when the sealing cover seals the opening, the control rod protrudes out of the outer wall of the inflow pipe.

Through adopting above-mentioned technical scheme, the slip of control lever passes through the connecting rod and drives the closing cap and around rotating in articulated department to the realization is to the open-ended opening and close, this simple structure, stability. When the opening is sealed through the sealing cover, the control rod does not fall into the inlet flow channel in a mode that the control rod protrudes out of the outer wall of the inlet flow pipe.

Further setting the following steps: the isolation box is arranged at the top of the flow inlet channel, and the hinge is arranged at the top of the sealing cover and connected with the wall of the flow inlet channel.

Through adopting above-mentioned technical scheme, this kind of setting mode installation is more simple and convenient and the structure is more stable.

Further setting the following steps: the opening is located the one side that keeps apart the chamber and is close to the inlet tube free end, the opening is along vertical direction downward gradually towards main part one side and is the slope setting.

Through adopting above-mentioned technical scheme, this kind of setting makes fluid medium can be better exert sealed open-ended effort to the closing cap in the in-process of transmission, and the pressure in the runner is advanced in the cooperation for control assembly when not controlling the closing cap, the closing cap can realize the self sealss to the opening under the effect of fluid force, like this when taking a sample or temperature measurement operation, just need not to control assembly, makes the operation more convenient. The inclined arrangement reduces the resistance when opening the cover, and simplifies the operation.

Further setting the following steps: and a sealing gasket is arranged between the sealing cover and the opening.

Through adopting above-mentioned technical scheme, sealed setting up of filling up increases the closing cap to the leakproofness of opening, avoids leaking the emergence.

Further setting the following steps: the sealing gasket is fixedly arranged on the sealing cover, when the opening is sealed by the sealing cover, the sealing gasket is provided with an extension section extending into the isolation cavity, and the extension section is tightly abutted and sealed with the wall of the isolation cavity.

Through adopting above-mentioned technical scheme, the extension section cooperation is kept apart the chamber wall and is realized that one is sealed, sealed pad cooperation opening realizes that two is sealed, reaches better sealed effect through the sealed mode of two. And the frictional resistance formed by the extension section and the isolation cavity wall can further increase the locking force of the sealing opening of the sealing cover, so that the sealing cover can form better self-sealing to the opening.

Further setting the following steps: the extension section is provided with a guide section which extends back to the sealing cover and gradually shrinks.

Through adopting above-mentioned technical scheme, the guide extension section that sets up the ability better gets into the isolation chamber, prevents to interfere the emergence, makes the operation more smooth and easy.

Further setting the following steps: the uniform body is provided with the flange on inlet tube and the play flow tube, all seted up the seal groove on the sealed face of flange, sealing member and operation mouth threaded connection.

Through adopting above-mentioned technical scheme, the setting of seal groove supplies the sealing washer installation, increases the area of contact between sealing washer and the flange to reach better sealed effect.

In conclusion, the utility model has the following beneficial effects: the utility model has the functions of temperature measurement and sampling, and has simple structure and low production cost.
