Description

Pressure Gauge-Mounted Valve Device {PRESSURE GAUGE-MOUNTED VALVE DEVICE}

The present invention relates to a valve device, and more particularly, to a valve device equipped with a pressure gauge.

Various pipes are used to transport liquid or gas, and various types of valves are installed in the right place of the pipe for controlling and controlling such transport. The operating principle of the valve may be different for each type, but basically, the opening and closing of the pipe or the flow rate can be adjusted as necessary by adjusting the degree of opening of the pipe flow path. It is also possible to install the valve on a specific pipe itself, but for convenience in manufacturing, construction, and use, a method of separately manufacturing a valve device and connecting the valve device between two pipe members connected to each other may be used. .

On the other hand, it is very important to measure the pressure in the pipe due to the nature of the fluid transport. If the pressure is excessive, durability or damage to the pipe and pipe accessories may be reduced, and in severe cases, a safety accident around the pipe may occur. In the case of installing a pressure gauge for pressure measurement on a pipe, a method of drilling a hole in the pipe and forming a thread on the inner circumferential surface may be used to install and fix the pressure gauge, but this method requires equipment and manpower and may have poor stability. In order to omit the process of separately drilling a hole for installing the pressure gauge, a method of installing the pressure gauge by forming a through hole in the valve device in advance has been proposed.

As described above, the valve device for mounting the pressure gauge may include a sealing member on the inner circumferential surface of the inner flow path of the main body of the valve device, and after forming the flow path having a fine diameter in the sealing member, the pressure gauge may be installed on the opposite side of the flow path. However, since the sealing member is formed of a flexible material such as plastic or rubber that can ensure watertightness in order to prevent water leakage between the piping and the valve device on both sides, the flow path is blocked by repeating contraction and expansion due to the nature of the material. occurs

In addition, in order to install a pressure gauge in the valve device, the pressure gauge may be installed in the nipple after the nipple is installed in the valve device, in which case the pressure gauge may be located too close to the valve device and piping. In the winter season, insulation is installed on the outside of the pipe. If the pressure gauge is installed too close to the pipe, the insulation material is mounted above the pressure gauge, making it impossible to check the measured value of the pressure gauge, or the insulation material is installed around the pressure gauge and avoids the pressure gauge. There is a problem that there is a vulnerability that is not kept warm.

The flange hole 132 may be formed at a portion of the valve body 100 as shown, or may be formed at predetermined intervals along the entire outer circumferential surface of the valve body 100 . In addition, although an example in which the flange is formed only in the middle of the outer circumferential surface of the valve body 100 is illustrated in the drawings, in some embodiments, the flange may be formed at two positions before and after the outer circumferential surface of the valve body 100 .

The contact member 102 is formed along the inner circumferential surface of the valve body 100 , and may be configured to be in close contact with the stopper member 120 when the stopper member 120 is in the closed position. To this end, the adhesion member 102 may be formed of a soft material such as synthetic rubber or synthetic resin to exhibit elastic deformation of a pre-designed degree.

A stopper member 120 may be provided in the fluid passage 101 of the valve body 100 . The stopper member 120 may be configured to move or rotate between an open position for opening the fluid passageway 101 and a closed position for closing the fluid passageway 101 . For example, for certain types of butterfly valves or ball valves, the stopper member 120 may be configured to move between an open position and a closed position by rotation, and for certain types of gate valves or check valves, the stopper member 120 may be configured to move. 120 may be configured to move between an open position and a closed position by translation. Of course, in some embodiments, the stopper member 120 may be moved by a combination of rotation and translation.

The stopper member 120 may have a shape corresponding to the shape of the fluid passage 101 , so that when the stopper member 120 is in the closed position, the outer circumferential surface of the stopper member 120 is on the inner circumferential surface of the adhesion member 102 . It is possible to completely close the fluid passage 101 by close contact. Although the figure shows an example in which the stopper member 120 also has a circular shape corresponding to the shape of the fluid passage 101 , in some embodiments, the stopper member 120 may have a different shape.

1 to 3, when the valve device 10 according to an embodiment of the present invention is implemented as a kind of butterfly valve, the stopper member 120 is rotated 90 degrees between the open position and the closed position. It can be implemented in the form of a moving disk. In this case, the stopper member 120 may be coupled to the shaft 110 and rotate according to the rotation of the shaft 110 . The stopper member 120 may have a through hole 123 through which the shaft 110 passes in the center thereof. The stopper member 120 can selectively open and close the fluid passage 101 by rotating in the fluid passage 101 with the shaft 110 as an axis.

In the stopper member 120 , a coupling hole 121 through which the coupling pin 121-1 passes may be formed in a portion adjacent to the shaft 110 . A plurality of coupling holes 121 may be formed along the longitudinal direction of the shaft 110 . The stopper member 120 may be coupled to the shaft 110 by a coupling pin 121-1 passing through the coupling hole 121 . The coupling direction of the coupling pin 121-1 may be a direction perpendicular to the longitudinal direction of the shaft 110 .

The shaft 110 may be connected to the driving unit 200 to transmit the force of the driving unit 200 to the stopper member 120 . When the valve device 10 according to an embodiment of the present invention is implemented as a butterfly valve as shown, the shaft 110 is formed in an axial shape, and one end is extended toward the inside of the fluid passage 101 and a stopper member It may be located in the through hole 123 formed in the 120 , and the other end may extend toward the outside of the valve body 100 . One end of the shaft 110 extending into the fluid passage 101 is introduced into the through hole 123 formed in the stopper member 120 , and may serve as a rotation shaft for the stopper member 120 to rotate. The other end of the shaft 110 extending to the outside of the valve body 100 may be connected to a driving unit 200 for rotating the shaft 110 .

Sealing members 122 spaced apart at regular intervals in the longitudinal direction of the shaft 110 may be provided on the outer peripheral surface of the shaft 110 . The sealing member 122 may increase airtightness between the shaft 110 and the valve body 100 . The sealing member 122 may be formed of a material such as synthetic rubber or synthetic resin, and may be formed of an O-ring having a circular cross section.

The driving unit 200 may be provided on the outside of the valve body 100 and may provide rotational force to the shaft 110 . The driving unit 200 may include a first gear 211 , a second gear 212 , a driving shaft 210 , and a gripping unit 220 .

The first gear 211 may have one surface connected to the end of the shaft 110 extending outwardly of the valve body 100 , and teeth protruding upward toward the center, such as a cone shape, may be formed on the other surface of the first gear 211 . The first gear 211 may rotate with the shaft 110 as a reference axis.

The second gear 212 is formed in the same shape as the first gear 211 , and the teeth formed on one surface of the second gear 212 rotate based on a rotation axis orthogonal to the first gear 211 . It may be meshed with the teeth of (211). And the drive shaft 210 may be connected to the other surface of the second gear 212 .

The driving shaft 210 may be formed in a shaft shape, one end connected to the second gear 212 , and the other end extending in a direction perpendicular to the longitudinal direction of the shaft 110 . The driving shaft 210 may serve as a rotation shaft of the second gear 212 .

In this embodiment, the first gear 211 and the second gear 212 may be configured as a bevel gear rotating with respect to the shaft 110 and the drive shaft 210 orthogonal to each other. The first gear 211 and the second gear 212 may transmit a rotational force generated due to the rotation of the driving shaft 210 to the shaft 110 extending in a direction orthogonal to the driving shaft 210 .

A gripper 220 may be provided at the other end of the drive shaft 210 . The gripper 220 may be formed in the form of a handle as a grippable portion in order for a user to easily rotate the driving shaft 210 . The gripper 220 may rotate the driving shaft 210 through a rotation operation. Of course, the driving shaft 210 may be driven by being connected to a separate motor (not shown). In some embodiments, the control unit 400 for controlling the operation of the driving unit 200 may be provided.

The penetration pipe 300 may be configured to partition the penetration passage 301 therein and penetrate the inside and outside of the adhesion member 102 at a predetermined point. Accordingly, the penetration passage 301 of the penetration pipe 300 may communicate with the fluid passage 101 inside the adhesion member 102 . The penetration pipe 300 may be formed of a hard material such as metal, may be formed of the same material as the valve body 100 , or may be formed integrally with the valve body 100 .

The penetration passage 301 of the penetration pipe 300 may have a very small diameter of 0.5 to 1 mm. The small diameter of the permeation passage 301 enables measurement of the pressure of the fluid without significantly affecting the flow of the fluid through the pipe. If the diameter of the permeation passage 301 is smaller than 0.5 mm, manufacturing difficulties may increase and the performance of pressure measurement may be deteriorated. If the diameter of the penetration passage 301 is greater than 1 mm, it may be necessary to additionally consider the flow of the fluid in the pipe and the flow and pressure of the branch pipe 500 and the pressure gauge 550 side.

When the penetration pipe 300 is not used, the through-hole formed in the adhesive member 102 made of a flexible material is subjected to repeated expansion and contraction due to the characteristics of the material of the adhesive member 102 and the pressure in the pressure gauge 550 due to irregular flow inlet. Measurements may be unstable and the through-hole itself may be occluded. However, in one embodiment of the present invention, the penetration tube 300 made of a hard material is formed to have a very small diameter, so that the occlusion of the penetration hole (ie, the penetration passage 301) can be prevented, and the penetration tube 300 is expanded. This is because not only is it formed of a material that is not vulnerable to over-shrinkage, but also the surface area exposed to the fluid is small, so the strength can be maintained to the extent that deformation does not occur.

The branch pipe 500 may extend to a predetermined length and may be configured to partition a branch flow path 501 through which a fluid can flow therein. One end of the branch pipe 500 may be connected to the valve body 100 , and the branch flow path 501 may be connected to communicate with the penetration flow path 301 of the penetration pipe 300 . Specifically, a connection hole 150 may be formed in the valve body 100 , and the branch pipe 500 may be connected such that the branch flow path 501 communicates with the connection hole 150 . The connection hole 150 may be formed at a position corresponding to the penetration passage 301 , and the inner diameter of the connection hole 150 may be the same as or larger than the diameter of the penetration passage 301 . When the inner diameter of the connection hole 150 is the same as the diameter of the penetration passage 301 , the penetration pipe 300 may be integrally formed with the valve body 100 . When the inner diameter of the connection hole 150 is larger than the diameter of the penetration passage 301 , the penetration pipe 300 may be formed to contact only the contact member 102 and not to contact the valve body 100 .

A pressure gauge 550 may be formed at the other end of the branch pipe 500 . Since the branch passage 501 of the branch pipe 500 communicates with the permeation passage 301 of the permeation tube 300 and the permeation passage 301 communicates with the fluid passage 101 , the pressure gauge 550 is the valve device 10 . ), it is possible to measure the pressure of the fluid passing through the fluid passage 101 on the passage of the pipe coupled to both sides.

1 and 2 , the branch pipe 500 may be provided with a siphon valve 520 . The siphon valve 520 may be configured to open and close the flow in the branch flow path 501 . For example, the hammer member 522 moves up and down according to the rotation of the siphon valve 520 at a specific point of the branch flow path 501 to open or close the passage 522 portion of the branch flow path 501. have. Of course, valves of various structures may be applied to the siphon valve 520 . When it is not necessary to measure the pressure of the fluid, the inflow of the fluid to the pressure gauge 550 may be closed by closing the siphon valve 520 .

The pressure gauge 550 is configured to measure the pressure of the fluid, and a Bourdon tube pressure gauge or other type of pressure gauge may be used. The pressure gauge 550 may be set to be suitable for measuring the pressure in the amount of fluid introduced through the penetration passage 301 of 0.5 to 1 mm as described above.

1 to 3 , it is possible to solve the problem that the pressure gauge 550 does not work properly because the hole having a fine diameter formed in the adhesion member 102 is blocked. In addition, by allowing the branch pipe 500 to extend beyond a predetermined length, it is possible to easily avoid the pressure gauge 550 and mount the insulation material when mounting the insulation material (not shown) around the valve device 10 .

4 is a cross-sectional view conceptually showing a pressure gauge mounted valve device according to another embodiment of the present invention. In FIG. 4 , the stopper member 120 is disposed in the open position, and the rotation range (a) of the stopper member 120 is also indicated.

In the embodiment shown in FIG. 2 , the penetration pipe 300 extends only to the inner surface of the adhesion member 102 and is formed so as not to protrude beyond the adhesion member 102 . In this case, since the permeation tube 300 is not located in the fluid passage 101, the influence on the flow of the fluid can be minimized, and the movement or rotation of the stopper member 120 is not prevented by the permeation tube 300. can

On the other hand, as in the embodiment shown in FIG. 4 , it is also possible to form the penetration pipe 300 so that the end of the penetration pipe 300 protrudes to the inside of the inner surface of the adhesion member 102 . In the example shown in FIG. 4 , the valve device 10 is a butterfly valve, and the stopper member 120 is implemented in the form of a disk that rotates only within the 90 degree rotation range (a). If the end of the permeation tube 300 is located within the movable rotation range (a) of the stopper member 120 , the permeation tube 300 interferes with the rotation of the stopper member 120 to prevent complete opening and closing of the valve device 10 . Although it may be difficult, as shown in FIG. 4 , when the penetration pipe 300 is formed at a position other than the 90 degree rotation range (a), the penetration pipe 300 does not interfere with the operation of the stopper member 120 .

By allowing the penetration tube 300 to protrude to the inside of the inner surface of the adhesion member 102, it is possible to more reliably prevent the hole formed in the adhesion member 102 from being blocked, and also to have a higher tolerance in the manufacturing process. This can reduce the defect rate.

When one end of the permeation tube 300 is formed to protrude inward of the inner surface of the adhesion member 102, the total length of the permeation tube 300, the protrusion length, the thickness of the adhesion member 102, the flow rate of the passing fluid, In consideration of the fluid resistance of the shape of the permeate tube 300 , care may be required so that the permeation tube 300 is not deformed such as being bent by the flow of the fluid.

When the penetration pipe 300 is not formed integrally with the valve body 100 and is coupled to the inside of the connection hole 150 of the valve body 100, after first forming the through hole 130 in the adhesion member 102 , the penetration pipe 300 may be inserted into the through hole 130 . According to the thickness of the adhesion member 102 and the length of the permeation tube 300, an embodiment in which the perforation member 102 is perforated by the insertion of the permeation tube 300 itself without first forming the through hole 130 will also be possible.

When the penetration pipe 300 is coupled to the inside of the connection hole 150 of the valve body 100, the configuration such that one end of the penetration pipe 300 protrudes to the inside of the inner surface of the contact member 102 is the penetration pipe ( 300) can be ensured to pass through the contact member 102, and can also be visually identified, thereby reducing the defect rate. Although not shown, in order to couple the penetration pipe 300 to the valve body 100 , threads may be formed in corresponding portions of the outer circumferential surface of the penetration pipe 300 and the inner circumferential surface of the connection hole 150 . It is also possible to form a thread in the portion in which the penetration pipe 300 is in contact with the adhesion member 102 . Due to the nature of the material, it is also possible to form a male thread only on the penetration pipe 300 without forming a female thread on the adhesion member 102 . Of course, it is also possible to combine the penetration pipe 300 by force fitting without forming a thread in the portion in contact with the contact member 102 .

The penetration pipe 300 may penetrate only the adhesion member 102 as described above, or may penetrate both the adhesion member 102 and the valve body 100 as shown in FIG. 4 .

In some embodiments of the present invention, the other end of the penetration pipe 300 may protrude to the outside of the valve body 100 . For example, when the branch pipe 500 is formed to be coupled to the valve body 100 , the other end of the penetration pipe 300 serves as a mark for the coupling position of the branch pipe 500 or the branch pipe 500 . It may serve to support the branch pipe 500 by being inserted into the. For another example, when the penetration pipe 300 is coupled to the valve body 100 , the configuration in which the other end of the penetration pipe 300 protrudes to the outside of the valve body 100 may hold the penetration pipe 300 . The coupling process can be significantly facilitated by providing a portion that can be used, and the effect can be particularly pronounced when the penetration tube 300 needs to be inserted through the adhesive member 102 with strong adhesive force.

5 is a cross-sectional view conceptually showing a pressure gauge mounted valve device according to another embodiment of the present invention.

In the pressure gauge-mounted valve device 10 of FIG. 5 , the penetration pipe 300 , the branch pipe 500 , and the pressure gauge 550 are configured as one module and may be coupled to the valve body 100 at the same time. In the embodiment of Figure 5, the penetration pipe 300 is formed at one end of the branch pipe 500, and the pressure gauge 550 is coupled to the other end. As described above, the penetration passage 301 of the penetration pipe 300 may communicate with the branch flow passage 501 , and may communicate with the pressure gauge 550 when the siphon valve 520 is opened.

A boss 155 for assisting insertion and coupling of the branch pipe 500 may be formed around the connection hole 150 of the valve body 100 . A female screw may be formed on the inner circumferential surface of the boss 155 , and a male screw may be formed on a corresponding portion of the outer circumferential surface of the branch pipe 500 , so that the branch pipe 500 may be coupled to the valve body 100 by screwing.

A through hole 130 may be formed in the adhesion member 102 . Accordingly, at the same time that the branch pipe 500 is inserted into the boss 155 , the penetration pipe 300 may be inserted into the through hole 130 of the adhesion member 102 . It is possible to form a thread in the penetration pipe 300, but it will be possible to use the coupling by force fitting by utilizing the properties of the material of the adhesion member 102. The penetration pipe 300 has a length such that when the branch pipe 500 is fully inserted, one end of the penetration pipe 300 reaches the inner surface of the adhesion member 102 or protrudes to the inside of the inner surface of the adhesion member 102 . can be formed. It is also possible to make the length of the penetration pipe 300 smaller than the length of the through hole 130 (or the thickness of the adhesion member 102 ). In this case, the through hole 130 when the stopper member 120 is in the closed position. ) close to the site, care may be required to avoid breaking the seal.

In the embodiment shown in FIG. 5 , it becomes possible to separate and replace the penetration pipe 300 , the branch pipe 500 , and the pressure gauge 550 as necessary. In addition, when the use of the pressure gauge 550 is unnecessary, the through hole 130 and/or the communication hole 150 may be blocked by separating them and using a separate stopper (not shown). In addition, in the case of mounting the insulating material to the valve device 10 and the connected pipe in winter, the insulating material is mounted in a state in which the branch pipe 500 and the pressure gauge 550 are separated, and a through hole is formed in the insulating material to form the branch pipe 500 ) and the pressure gauge 550 by re-combining the insulation can be mounted in a simple way.

According to some embodiments of the present invention described above, a structure capable of solving the problem that the through-hole is blocked in the adhesion member 102 formed of a soft material is proposed, and a detailed structure capable of easily manufacturing such a structure is provided. presented In addition, some embodiments of the present invention can solve the difficulty in mounting the insulating material to the valve equipped with a pressure gauge, and the branch pipe 500 is extended by a predetermined length, and through a structure in which it is detachably coupled It makes it easier to install and remove the insulation.

Although the above has been described with reference to some embodiments of the present invention, those of ordinary skill in the art may change the present invention in various ways without departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that modifications and variations are possible.
