Description

Technical Field

[0001] The present invention relates to the technical field of temperature and pressure reducing devices, in particular to a temperature and pressure reducing device with a limiting structure. Background Art

[0002] A desuperheater and pressure reducer is a device that reduces high-temperature and high-pressure steam to low-pressure and low-temperature steam that can be used by customers. Taking the boiler superheater outlet as an example, the steam generated by the boiler passes through the superheater outlet to the steam turbine to perform work. The steam turbine has a range requirement for the parameters of the incoming steam. If the steam parameters at the superheater outlet exceed the upper limit required by the steam turbine, it will cause damage to the steam turbine, so a desuperheater and pressure reducer is needed to reduce the parameters to within the applicable range.

[0003] Announcement No. CN217328651U discloses a temperature reducing and pressure reducing device with a quick limit structure, which is provided with a delivery pipe 1, a delivery pipe 2, a temperature reducing and pressure reducing device, a one-way valve, a baffle 1, a rotating rod 1, a driving wheel, a belt, a driven wheel, a rotating rod 2, a baffle 2, and a delivery pipe 3, so that cooling water enters the temperature reducing and pressure reducing device through the delivery pipe 2, and the one-way valve is opened to allow the cooling water to enter the temperature reducing and pressure reducing device. The cooling water drives the baffle 1 to move, and the rotating rod 1 provides a supporting force for the baffle 1. The rotating rod 1 drives the driving wheel to rotate, and the driving wheel and the driven wheel are connected by a belt transmission. The driven wheel drives the rotating rod 2 to rotate, and the rotating rod 2 drives the baffle 2 to move, so that the high-temperature gas intermittently passes through the delivery pipe 3 and enters the temperature reducing and pressure reducing device for temperature reduction, thereby preventing too much high-temperature gas from entering the temperature reducing and pressure reducing device at one time, resulting in poor temperature reduction effect. However, the following problems still exist in the actual use of this patent:

[0004] Although the desuperheater and pressure reducer with a quick limiting structure can cool high-temperature steam, it does not reinforce the high-temperature steam entry point of the desuperheater and pressure reducer, resulting in uneven stress distribution in the pipeline system and prone to cracks. When installing the desuperheater and pressure reducer, it is impossible to provide reasonable limiting support for the desuperheater and pressure reducer, resulting in uneven stress distribution and cracks, thereby affecting the service life of the desuperheater and pressure reducer. At the same time, the desuperheater and pressure reducer has a poor cooling effect due to improper positioning of the water spraying device or uneven water spraying.

[0005] Therefore, a temperature and pressure reducing device with a limiting structure is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The object of the present invention is to provide a temperature-reducing and pressure-reducing device with a limiting structure to solve the problem proposed in the above-mentioned background technology that the high-temperature steam entry point of the temperature-reducing and pressure-reducing device is not reinforced, resulting in uneven stress distribution of the pipeline system and easy cracking. When installing the temperature-reducing and pressure-reducing device, the temperature-reducing and pressure-reducing device cannot be reasonably limited and supported, resulting in uneven stress distribution and cracks, thereby affecting the service life of the temperature-reducing and pressure-reducing device.

[0021] Preferably, the air pump is rotatably connected to a deflation rotating rod on one side close to the second one-way valve, a deflation knob is fixedly installed on the top of the deflation rotating rod, a deflation cam is fixedly installed on the bottom of the deflation rotating rod, and connecting blocks are symmetrically installed on the upper and lower ends of the reinforcement ring away from the connecting hinge, the internal thread of the connecting block is connected to a connecting bolt, and the outer thread of the connecting bolt is connected to a fixing nut.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: in this temperature reducing and pressure reducing device with a limiting structure, after the high-temperature steam inside the temperature reducing and pressure reducing valve is fully cooled, the pressure inside the temperature reducing and pressure reducing valve gradually decreases, and under the elastic force of the pressure spring, the first sealing ring and the second sealing ring are lowered again, thereby increasing the amount of high-temperature steam entering, and the amount of high-temperature steam entering can be automatically adjusted according to the pressure inside the temperature reducing and pressure reducing valve, thereby improving the cooling effect of the high-temperature steam, and reinforcing the part of the temperature reducing and pressure reducing valve where the high-temperature steam enters by means of the cooling airbag and the reinforcing pressure block, thereby improving the strength of the temperature reducing and pressure reducing valve, and avoiding the phenomenon of cracks in the temperature reducing and pressure reducing valve due to uneven stress distribution, which affects the service life of the temperature reducing and pressure reducing valve. The specific contents are as follows:

[0023] 1. By setting up the temperature reduction and pressure reduction mechanism, not only can the elastic force of the pressure spring and the spring telescopic rod be utilized, but when the internal pressure of the temperature reduction and pressure reducing valve increases, the pressure spring is contracted by the pressure transmitted from the bottom, thereby driving the first supporting bottom plate, the connecting column, the first sealing ring and the second sealing ring to rise. Since the density and number of holes in the first sealing ring are greater than those in the second sealing ring, the sealing effect of the second sealing ring is better than that of the first sealing ring. Therefore, as the first sealing ring and the second sealing ring rise, the amount of high-temperature steam entering the first connecting pipe is reduced, and the high temperature inside the temperature reduction and pressure reducing valve is reduced. After the steam is sufficiently cooled, the pressure inside the temperature-reducing and pressure-reducing valve gradually decreases. Under the elastic force of the pressure spring, the first sealing ring and the second sealing ring are lowered again, thereby increasing the inlet amount of high-temperature steam. The inlet amount of high-temperature steam can be automatically adjusted according to the pressure inside the temperature-reducing and pressure-reducing valve, thereby improving the cooling effect of high-temperature steam. When the high-temperature gas enters the temperature-reducing and pressure-reducing valve, the structural characteristics of the rotating connecting shaft and the conveying spiral blade can be utilized to realize the rotation of the rotating connecting rod and the conveying auger, which can not only realize the conveying of steam, but also drive the bottom breaking hammer and breaking thorn to rotate. When spraying cooling water, the cooling water is quickly dispersed by the scattering thorns to form water mist or water splash, which can fully contact with the high-temperature steam to achieve the effect of rapid cooling. The first valve spring inside the first valve body and the elastic force of the first valve telescopic rod can realize the engagement connection between the first piston and the first valve body, so that the high-temperature steam can only flow in one direction without backflow, thereby affecting the cooling efficiency of the high-temperature steam. The cooling water can be recycled by setting a recovery cylinder and a recovery pump, and the cooling water is pumped into the To the connection water pipe and the water spray ring, and spray out through the inclined nozzle, so as to facilitate the cooling of the high-temperature steam. Through the elastic force of the second valve telescopic rod and the second valve spring inside the second valve body, when the pressure inside the temperature-reducing and pressure-reducing valve is too high, it means that the high-temperature steam has not cooled to the specified steam temperature. The second piston is engaged with the second valve body and the steam cannot flow out. When the steam is cooled to the specified temperature, the elastic force of the second valve spring separates the second piston from the second valve body, and the steam can flow out through the second valve body, so as to facilitate the cooling of the high-temperature steam.

[0024] 2. By setting up a supporting reinforcement mechanism, not only can the support column on the top of the second supporting base plate be used to support the reinforcement ring, but the reinforcement ring can also be rotated by connecting the hinge, which is convenient for the installation of the reinforcement ring. By turning the reinforcement knob, the reinforcement bolt is driven to rotate on the internal thread of the reinforcement ring, and the elastic force of the reinforcement spring is used to reinforce the temperature reduction and pressure relief valve. By injecting cooling gas into the interior of the cooling airbag, not only the temperature reduction and pressure relief valve can be reinforced, but the cooling gas can also be used to cool the temperature reduction and pressure relief valve, thereby further improving the cooling effect of the temperature reduction and pressure relief valve. Cooling can be achieved through the first one-way valve and the second one-way valve inside the air pump. The air bag is closed to prevent gas from flowing out. At the same time, manual inflation can be achieved by manually squeezing the air pump to increase the supporting force of the cooling air bag. When the cooling air bag needs to be deflated, the deflation knob can be turned to drive the deflation rotating rod and the deflation cam to rotate. When the deflation cam squeezes the piston inside the second one-way valve, the piston inside the first one-way valve is manually squeezed to achieve the deflation effect, which is convenient for replacing the cooling gas. The part where high-temperature steam enters the temperature and pressure reducing valve is reinforced by the cooling air bag and the reinforcement block, thereby improving the strength of the temperature and pressure reducing valve and avoiding cracks in the temperature and pressure reducing valve due to uneven stress distribution, which affects the service life of the temperature and pressure reducing valve.

[0038] See also Figures 1-11The present invention provides a technical solution: a temperature reducing and pressure reducing device with a limiting structure, comprising a temperature reducing and pressure reducing mechanism 1, and a water spray ring 128 installed inside the temperature reducing and pressure reducing mechanism 1, a support and reinforcement mechanism 2 is provided at the bottom of the temperature reducing and pressure reducing mechanism 1, and a cooling air bag 210 is provided inside the support and reinforcement mechanism 2, the temperature reducing and pressure reducing mechanism 1 comprises a temperature reducing and pressure reducing valve 101, a support top plate 102 is provided on the top inner side of the temperature reducing and pressure reducing valve 101, a pressure spring 103 is fixedly installed on the bottom of the support top plate 102, a spring telescopic rod 104 is provided inside the pressure spring 103, wherein a first support bottom plate 105 is fixedly installed on the bottom of the spring telescopic rod 104 and the pressure spring 103, and the bottom outer side of the first support bottom plate 105 A plurality of connecting columns 106 are fixedly installed, wherein a first blocking ring 107 is fixedly installed at the bottom of the connecting column 106, a second blocking ring 108 is fixedly installed at the bottom of the first blocking ring 107, a rotating connecting shaft 109 is rotatably connected to the center position of the bottom of the first supporting base plate 105, a conveying spiral blade 110 is fixedly installed on the outer side of the rotating connecting shaft 109, a rotating connecting rod 111 is fixedly installed at the bottom of the rotating connecting shaft 109, a conveying auger 112 is fixedly installed on the outer side of the rotating connecting rod 111, a breaking hammer 113 is fixedly installed at the bottom of the rotating connecting rod 111, and a breaking thorn 114 is fixedly installed on the outer side of the breaking hammer 113. The elastic force of the pressure spring 103 and the spring telescopic rod 104 is used to reduce the weight of the goods. When the internal pressure of the temperature reducing valve 101 increases, the pressure spring 103 contracts due to the pressure transmitted from the bottom, thereby driving the first supporting base plate 105, the connecting column 106, the first sealing ring 107 and the second sealing ring 108 to rise. Since the density and number of holes in the first sealing ring 107 are greater than those in the second sealing ring 108, the sealing effect of the second sealing ring 108 is better than that of the first sealing ring 107. Therefore, as the first sealing ring 107 and the second sealing ring 108 rise, the amount of high-temperature steam entering the first connecting pipe 115 is reduced. After the high-temperature steam inside the temperature reducing valve 101 is fully cooled, the pressure inside the temperature reducing valve 101 gradually decreases. Under the elastic force of the pressure spring 103, the first sealing ring 107 and the second sealing ring 108 descend again, thereby increasing the inlet amount of high-temperature steam, and can automatically adjust the inlet amount of high-temperature steam according to the pressure inside the temperature-reducing and pressure-reducing valve 101, thereby improving the cooling effect of the high-temperature steam. When the high-temperature gas enters the temperature-reducing and pressure-reducing valve 101, the structural characteristics of the rotating connecting shaft 109 and the conveying spiral blade 110 can be utilized to realize the rotation of the rotating connecting rod 111 and the conveying auger 112, which can not only realize the transportation of steam, but also drive the bottom breaking hammer 113 and breaking thorn 114 to rotate. When spraying cooling water, the cooling water is quickly broken up by the breaking thorn 114, thereby forming water mist or water splash, which can fully contact with the high-temperature steam to achieve a rapid cooling effect.

By utilizing the elastic force of the first valve spring 119 and the first valve telescopic rod 120 inside the first valve body 116, the first piston 121 and the first valve body 116 can be engaged with each other, so that high-temperature steam can only flow in one direction without backflow, thereby affecting the cooling efficiency of the high-temperature steam. By arranging a recovery cylinder 122 and a recovery pump 123, the cooling water can be Recycling, at the same time, cooling water is pumped into the connecting water pipe 127 and the water spray ring 128 through the water pump 126, and sprayed out through the inclined nozzle 129, which is convenient for cooling the high-temperature steam. Through the elastic force of the second valve telescopic rod 133 and the second valve spring 134 inside the second valve body 131, when the internal pressure of the temperature reduction and pressure reducing valve 101 is too large, it means that the high-temperature steam has not cooled to the specified steam temperature.

[0040] The support and reinforcement mechanism 2 includes a second support base plate 201, and the top of the second support base plate 201 is rotatably connected to the support column 202. The top of the support column 202 is threadedly connected to the reinforcement ring 203. A connecting hinge 204 is symmetrically provided between the two reinforcement rings 203. The two reinforcement rings 203 are rotatably connected through the connecting hinge 204. The inner periphery of the reinforcement ring 203 is threadedly connected to the reinforcement bolt 205. The end of the reinforcement bolt 205 is fixedly installed with a reinforcement knob 206. One end of the reinforcement bolt 205 is rotatably connected to a rotating bearing 207.

On the inside, an airbag connecting tube 211 is fixedly installed at one end of the cooling airbag 210, and the reinforcement ring 203 is supported by the support column 202 on the top of the second support base plate 201. At the same time, the reinforcement ring 203 is rotated by the connecting hinge 204, which facilitates the installation of the reinforcement ring 203. By rotating the reinforcement knob 206, the reinforcement bolt 205 is driven to rotate on the internal thread of the reinforcement ring 203, and the elastic force of the reinforcement spring 208 is used to make the reinforcement pressure block 209 reinforce the temperature reduction and pressure reducing valve 101. By injecting cooling gas into the interior of the cooling airbag 210, not only can the temperature reduction and pressure reducing valve 101 be reinforced, but the cooling gas can also be used to cool the temperature reduction and pressure reducing valve 101, thereby further improving the cooling effect of the temperature reduction and pressure reducing valve 101.

[0041] An air pump 212 is fixedly installed on the outside of the air bag connecting tube 211, and a first one-way valve 213 and a second one-way valve 214 are fixedly installed inside the air pump 212.

The first one-way valve 213 and the second one-way valve 214 inside the air pump 212 can achieve the sealing of the cooling air bag 210. , to avoid the phenomenon of gas outflow, and at the same time, manual inflation can be achieved by manually squeezing the air pump 212 to increase the supporting force of the cooling air bag 210. When the cooling air bag 210 needs to be deflated, the deflation knob 216 can be rotated to drive the deflation rotating rod 215 and the deflation cam 217 to rotate.

[0042] Working principle: Before using this kind of temperature and pressure reducer with a limit structure, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 11As shown, first, the support column 202 on the top of the second support base plate 201 is used to support the reinforcement ring 203, and the reinforcement ring 203 is rotated by connecting the hinge 204 to facilitate the installation of the reinforcement ring 203. By rotating the reinforcement knob 206, the reinforcement bolt 205 is driven to rotate on the internal thread of the reinforcement ring 203, and the elastic force of the reinforcement spring 208 is used to make the reinforcement pressure block 209 reinforce the temperature reduction and pressure reducing valve 101. By injecting cooling gas into the interior of the cooling airbag 210, not only can the temperature reduction and pressure reducing valve 101 be reinforced, but the cooling gas can also be used to cool the temperature reduction and pressure reducing valve 101, further improving the cooling effect of the temperature reduction and pressure reducing valve 101. The cooling gas can be realized through the first one-way valve 213 and the second one-way valve 214 inside the air pump 212. The closure of the bag 210 prevents the gas from flowing out. At the same time, manual inflation can be achieved by manually squeezing the air pump 212 to increase the supporting force of the cooling air bag 210. When the cooling air bag 210 needs to be deflated, the deflation knob 216 can be rotated to drive the deflation rotating rod 215 and the deflation cam 217 to rotate. When the deflation cam 217 squeezes the piston inside the second one-way valve 214, the piston inside the first one-way valve 213 is manually squeezed to achieve the deflation effect, which is convenient for replacing the cooling gas. The part where high-temperature steam enters the temperature-reducing and pressure-reducing valve 101 is reinforced by the cooling air bag 210 and the reinforcement pressure block 209, thereby improving the strength of the temperature-reducing and pressure-reducing valve 101 and avoiding cracks in the temperature-reducing and pressure-reducing valve 101 due to uneven stress distribution, which affects the service life of the temperature-reducing and pressure-reducing valve 101.

[0043] Secondly, by utilizing the elastic force of the pressure spring 103 and the spring telescopic rod 104, when the internal pressure of the temperature-reducing and pressure-reducing valve 101 increases, the pressure spring 103 contracts due to the pressure transmitted from the bottom, thereby driving the first supporting bottom plate 105, the connecting column 106, the first sealing ring 107 and the second sealing ring 108 to rise. Since the density and number of holes in the first sealing ring 107 are greater than those in the second sealing ring 108, the sealing effect of the second sealing ring 108 is better than that of the first sealing ring 107. Therefore, as the first sealing ring 107 and the second sealing ring 108 rise, the amount of high-temperature steam entering the first connecting pipe 115 is reduced. After the high-temperature steam inside the temperature-reducing and pressure-reducing valve 101 is fully cooled, the pressure inside the temperature-reducing and pressure-reducing valve 101 gradually decreases. 03, the first sealing ring 107 and the second sealing ring 108 are lowered again, thereby increasing the amount of high-temperature steam entering, and can automatically adjust the amount of high-temperature steam entering according to the pressure inside the temperature-reducing and pressure-reducing valve 101, thereby improving the cooling effect of the high-temperature steam. When the high-temperature gas enters the temperature-reducing and pressure-reducing valve 101, the structural characteristics of the rotating connecting shaft 109 and the conveying spiral blade 110 can be used to realize the rotation of the rotating connecting rod 111 and the conveying auger 112, which can not only realize the transportation of steam, but also drive the bottom breaking hammer 113 and breaking thorn 114 to rotate. When spraying cooling water, the cooling water is quickly broken up by the breaking thorn 114, thereby forming water mist or water splash, which can fully contact with the high-temperature steam to achieve a rapid cooling effect.

[0044] Finally, by utilizing the elastic force of the first valve spring 119 and the first valve telescopic rod 120 inside the first valve body 116, the first piston 121 can be connected to the first valve body 116, so that the high-temperature steam can only flow in one direction without backflow, thereby affecting the cooling efficiency of the high-temperature steam. The cooling water can be recycled by setting the recovery cylinder 122 and the recovery pump 123. At the same time, the cooling water is pumped into the connecting water pipe 127 and the water spray ring 128 by the water pump 126, and sprayed out through the inclined nozzle 129, which is convenient for high-temperature steam cooling. The steam is cooled by the elastic force of the second valve telescopic rod 133 and the second valve spring 134 inside the second valve body 131. When the pressure inside the temperature-reducing and pressure-reducing valve 101 is too high, it means that the high-temperature steam has not cooled to the specified steam temperature. The second piston 135 is engaged with the second valve body 131, and the steam cannot flow out. When the steam is cooled to the specified temperature, the elastic force of the second valve spring 134 separates the second piston 135 from the second valve body 131, and the steam can flow out through the second valve body 131, thereby facilitating the cooling of the high-temperature steam.
