Regulating valve and bathroom equipment

Technical Field

The utility model relates to a bathroom technical field especially relates to a governing valve and bathroom equipment.

Background

The sanitary ware is a product applied to a toilet or a bathroom, and can be a closestool, a squatting pan, a hand basin or a bathtub and the like. In order to wash articles or parts of a user's body or clean sanitary equipment, corresponding waterways are generally provided in the sanitary equipment to control the flow of water and perform corresponding washing or cleaning functions.

Along with the gradual perfection of the functions of the sanitary equipment, the control of the water channel in the sanitary equipment is gradually complicated. In order to achieve the corresponding control effect, the pressure difference between the two flow channels needs to be maintained within a predetermined range in the waterway of some sanitary equipment. In the conventional technology, the pressure difference between the output sections of the two flow channels is kept stable by means of electrical measurement and pressure supplement by a pump body, so that the overall cost of the sanitary ware is difficult to reduce.

SUMMERY OF THE UTILITY MODEL

Therefore, it is necessary to provide a regulating valve and a sanitary ware, which can maintain a stable pressure difference between the output ends of the two flow channels by means of electrical measurement and pressure supplement of the pump body, and thus the overall cost of the sanitary ware is high.

A regulator valve having a primary flow passage, comprising:

a housing assembly;

the separation assembly can separate the inner space of the shell assembly into at least a flow cavity and a regulating cavity; the separation component moves relative to the shell component under the change of the pressure difference value of the medium; the adjusting cavity is communicated with the outer flow passage;

an elastic element connected to the partition assembly and capable of at least partially equalizing the medium pressure in the through-flow chamber beyond the regulating chamber; and

the valve core is connected with the separation component and is matched with the shell component to form an inner valve port; the inner valve port generates scaling change when the separation component moves relative to the shell component; the inner valve port and the through flow cavity are flow nodes of the main flow passage.

According to the regulating valve, the separating assembly is located between the through flow cavity and the regulating cavity, the two sides of the separating assembly are respectively subjected to the medium pressure from the through flow cavity and the medium pressure from the regulating cavity, and the elastic piece generates elastic forces with different sizes through elastic deformation with different amplitudes so as to balance the difference value of the two medium pressures. When the pressure of the outer runner or the main runner changes, the medium pressure difference born by the separation assembly changes, and the elastic element correspondingly changes the deformation amplitude. The separating component moves to different positions correspondingly relative to the shell component. Because the valve core is connected with the separation assembly and is matched with the shell assembly to form the inner valve port, the valve core can cause the scaling change of the inner valve port in the process of moving along with the separation assembly. The internal valve port adjusts the pressure drop of the medium in the main flow passage when the scaling is changed. Because the medium in the main flow channel enters the through flow cavity after flowing through the inner valve port, the pressure in the through flow cavity can be adjusted after the pressure drop generated by the inner valve port is changed, and the difference value between the pressure of the outer flow channel and the pressure of the main flow channel can be maintained in a preset range when the adjusting direction of the pressure in the through flow cavity is consistent with the change of the pressure in the outer flow channel. The regulating valve utilizes the movable feedback of the separating component and the valve core to regulate the pressure drop of the inner valve port, so that the pressure of the main runner changes along with the pressure of the outer runner, and an electric measurement and a pump body are not needed, thereby being beneficial to reducing the overall cost of the sanitary ware.

In one embodiment, the housing assembly has a first wall block with a valve opening; the valve core is provided with a narrowing change part, and the narrowing change part is matched with the edge of the valve hole to form the inner valve port.

The utility model provides a bathroom equipment.

In some embodiments, the sanitary arrangement is provided with at least two passages for guiding the flow of the medium. Further, the path may have an on state or an off state. Specifically, the medium may be a liquid, and more specifically, the medium may be water, a liquid medicine, or a detergent. The medium may also be a gas.

In one embodiment, the pathway is a spray wash pathway capable of directing a spray of the medium to the human body. The end of the spray passage may be located at a spray gun or a spray nozzle. In another embodiment, the passage is a flushing passage, capable of guiding the medium jet to the body of the sanitary arrangement. In particular, the sanitary arrangement may be a toilet, or a combination of a squatting pan and a water tank arrangement. In another embodiment, the passageway is an airflow passageway capable of directing an airflow. The airflow path may also be used to interface with an atmospheric pressure environment.

In some embodiments, as shown in fig. 1 and 5, the sanitary equipment includes a regulating valve 10, and the regulating valve 10 has a main flow passage, and the main flow passage is used as one section of a passage in the sanitary equipment. Any other passage in the sanitary equipment is used as the outer flow passage 800, that is, a passage other than the passage where the control valve 10 is located is used as the outer flow passage 800. The regulator valve 10 is used to maintain a predetermined range of pressure difference between the output sections of the two passages. Specifically, it is assumed that the main flow channel is used for passing a first type of medium, and the outer flow channel 800 is used for passing a second type of medium.

In one embodiment, the control valve 10 may be disposed in one of the spray passages, i.e., the main flow passage is a part of one of the spray passages, and the other spray passage is the outer flow passage 800. The pressure difference of the output water flows of the two spray passages is kept stable through the control of the regulating valve 10.

In one embodiment, the control valve 10 may be disposed in one spray passage, and the other flow passage may be used as the outer flow passage 800. The pressure difference between the output air flow of the air flow passage and the output water flow of the spray passage is kept stable through the control of the regulating valve 10. Further, when the air flow passage is butted against the atmospheric pressure environment, since the pressure value of the atmospheric pressure environment can be a constant value, the pressure of the output water flow of the spray rinsing passage can be maintained constant.

Referring to fig. 1 to 5, the present invention provides a control valve 10.

In some embodiments, as shown in fig. 2 and 3 in combination, the regulator valve 10 includes: housing assembly 20, partition assembly 30, resilient member 40, and valve cartridge 50. The partition member 30 can partition the inner space of the case member 20 into at least the flow passage chamber 201 and the regulation chamber 202. The partition member 30 is movable relative to the housing member 20 by a change in a difference in pressure of the medium. The adjustment chamber 202 is used to connect the outer flow passage 800. The resilient member 40 is connected to the partition member 30 and is capable of at least partially equalizing the pressure of the medium in the flow-through chamber 201 beyond the regulation chamber 202. Valve cartridge 50 is coupled to spacer assembly 30 and cooperates with housing assembly 20 to form an internal valve port 501. The internal valve port 501 is scaled when the partition assembly 30 moves relative to the housing assembly 20. The internal valve port 501 and the through-flow cavity 201 are flow nodes of the main flow passage.

Since the partition assembly 30 is located between the flow-through cavity 201 and the adjustment cavity 202, the two sides of the partition assembly 30 are respectively subjected to the medium pressure from the flow-through cavity 201 and the medium pressure from the adjustment cavity 202, and the elastic member 40 generates elastic forces of different magnitudes through elastic deformation of different magnitudes to balance the difference between the two medium pressures. When the pressure of the outer flow channel 800 or the main flow channel changes, the pressure difference of the medium borne by the separation assembly 30 changes, and the elastic member 40 correspondingly changes in deformation amplitude. The partition member 30 is correspondingly movable to different positions with respect to the housing member 20. Because valve element 50 is connected to partition assembly 30 and cooperates with housing assembly 20 to form internal valve port 501, the movement of valve element 50 with partition assembly 30 can cause a change in the scaling of internal valve port 501. The internal valve port 501 adjusts the pressure drop of the medium in the main flow channel when the scaling is changed. Because the medium in the main runner enters the through-flow cavity 201 after flowing through the inner valve port 501, the pressure in the through-flow cavity 201 can be adjusted after the pressure drop generated by the inner valve port 501 changes, and the pressure difference between the outer runner 800 and the main runner can be maintained in a preset range when the adjustment direction of the pressure in the through-flow cavity 201 is consistent with the change of the pressure in the outer runner 800. Because the regulating valve 10 utilizes the movable feedback of the separation assembly 30 and the valve core 50 to regulate the pressure drop of the inner valve port 501, the change of the pressure intensity of the main runner along with the pressure intensity of the outer runner 800 is realized, and an electric measurement and a pump body are not needed, thereby being beneficial to reducing the overall cost of the sanitary ware.

In particular, since the resilient member 40 serves to at least partially equalize the pressure of the medium in the through-flow chamber 201 beyond the regulation chamber 202, the pressure in the through-flow chamber 201 is greater than the pressure in the outer flow channel 800 in the intended operating state in this embodiment. If the pressure in the outer flow channel 800 is increased relative to the pressure in the flow cavity 201, under static analysis, the pressure of the first medium to the medium of the separation member 30 is not changed, and the pressure of the second medium to the medium of the separation member 30 is increased, so that the separation member 30 can move toward the direction of compressing the flow cavity 201 in combination with the elastic force of the elastic member 40. As the partition assembly 30 moves in the direction of the compression flow chamber 201, the inner valve port 501 amplifies and reduces the pressure drop it creates. Under the condition that the input pressure of the main runner is not changed, the amplification of the inner valve port 501 can increase the pressure of the through-flow cavity 201, and the increase of the pressure of the outer runner 800 generates a counteracting effect, so that the pressure difference between the outer runner 800 and the main runner is maintained stable.

If the pressure in the flow-through cavity 201 increases relative to the pressure in the outer flow channel 800, under static analysis, the pressure of the second medium on the separating element 30 is not changed, while the pressure of the first medium on the separating element 30 increases, and the elastic force of the elastic element 40 is not enough to counteract the difference of the medium pressures applied to the separating element 30, so that the separating element 30 moves toward the compression adjusting cavity 202. As the dividing assembly 30 moves in the direction of compressing the adjustment chamber 202, the inner valve port 501 contracts and increases the pressure drop it creates. Under the condition that the input pressure of the main runner is not changed, the inner valve opening 501 is reduced, so that the pressure of the through-flow cavity 201 is reduced, the pressure increase of the through-flow cavity 201 is counteracted, and the pressure difference value between the outer runner 800 and the main runner is kept stable.

Specifically, the flow-through node is a node through which the main flow path must pass, and no branch flow is formed in parallel relation with the node. The medium pressure refers to a pressure at which the medium in the flow-through chamber 201 or the regulating chamber 202 pressurizes the partition member 30 under its own pressure.

In some embodiments, as shown in connection with fig. 3, the housing assembly 20 has a first wall block 211, the first wall block 211 being provided with a valve aperture 212. The valve element 50 has a variable constriction 51, and the variable constriction 51 cooperates with the edge of the valve hole 212 to form an inner valve port 501. Specifically, the section of the narrowing varying portion 51 in a direction parallel to the plane of the valve hole 212 is a cross section, and the size of the cross section increases in a single direction or decreases in a single direction. Understandably, the cross section is a section of the narrowed changing portion 51 perpendicular to the axial direction of the spool 50.

In one embodiment, when the narrowing varying portion 51 is at any position, one of the cross sections and the valve hole 212 are located on the same plane, and the edge of the cross section and the edge of the valve hole 212 cooperate to form the internal valve port 501. More specifically, the inner valve port 501 is annular. Since the valve core 50 moves relative to the housing assembly 20 along with the partition assembly 30, when the partition assembly 30 moves to different positions relative to the housing assembly 20, the inner valve ports 501 with different sizes are formed between the narrowed variable portion 51 and the edge of the valve hole 212.

Further, the small end 511 of the narrowing varying portion 51 is between the large end 512 of the narrowing varying portion 51 and the partition member 30. The first wall block 211 is between the large end 512 of the narrowing variation 51 and the partition assembly 30. The size of the cross-section varies progressively in the direction of the transition from the small end 511 to the large end 512. When the pressure of the medium in the external flow channel 800 increases relative to the pressure of the medium in the flow chamber 201, the pressure of the medium generated by the medium in the adjustment chamber 202 on the partition member 30 increases, so that the partition member 30 moves toward the valve hole 212, and the large end 512 of the narrowing varying portion 51 moves away from the valve hole 212, so that the internal valve port 501 increases.

In some embodiments, as shown in fig. 3, the housing assembly 20 has a limiting cylinder 221, and one end of the valve core 50 away from the partition assembly 30 is movably disposed through the limiting cylinder 221. The limiting cylinder 221 can limit the moving direction of the valve core 50. Specifically, in the process that the valve core 50 moves relative to the housing assembly 20, one end of the valve core 50 away from the partition assembly 30 is always movably inserted into the limiting cylinder 221. After the moving direction of the valve core 50 is limited, because the partition assembly 30 is connected to the valve core 50, the moving direction of the partition assembly 30 can be limited by the valve core 50, the influence on the matching relationship between the valve core 50 and the housing assembly 20 due to the deflection of the partition assembly 30 is avoided, the shape stability of the inner valve port 501 is ensured, and the reduction of the adjustment accuracy of the inner valve port 501 due to the irregular size change of the inner valve port 501 is avoided.

Further, the outer diameter of the end of the valve core 50 far away from the partition assembly 30 is matched with the inner diameter of the limiting cylinder 221 in size, so that the valve core 50 moves relative to the housing assembly 20 along the axial direction of the valve core 50. More specifically, the inner diameter of the limiting cylinder 221 is 100% to 115% of the outer diameter of one end of the valve core 50 far away from the partition assembly 30, so that the limiting cylinder 221 limits the valve core 50, and simultaneously, large friction between the limiting cylinder 221 and the valve core 50 is avoided, and the valve core 50 is prevented from bearing excessive resistance of the limiting cylinder 221. Meanwhile, because the clearance between the limiting cylinder 221 and the valve core 50 is small, the first medium entering from the input port 203 can be prevented from overflowing to the through-flow cavity 201 through the clearance between the valve core 50 and the limiting cylinder 221, the first medium entering the regulating valve 10 from the input port 203 is ensured to enter the through-flow cavity 201 through the inner valve port 501, and the inner valve port 501 fully plays a regulating role.

In one embodiment, a sealing member 24 is supported between the valve core 50 and the limiting cylinder 221 to further limit the first type of medium from overflowing from a gap between the valve core 50 and the limiting cylinder 221. Further, the valve element 50 is inserted into an end surface of one end of the limiting cylinder 221 and forms a variable chamber 222 with a variable space size with a partial inner wall of the limiting cylinder 221, the limiting cylinder 221 is provided with a side hole 223, and the variable chamber 222 is communicated to the through-flow cavity 201 through the side hole 223. In the process that the valve core 50 moves to the limiting cylinder 221, a negative pressure environment is prevented from being formed in the variable chamber 222, and the movement of the valve core 50 is prevented from being influenced by the negative pressure.

In some embodiments, as shown in connection with fig. 3, the housing assembly 20 has a second wall block 216. The second wall block 216 is disposed around the inner valve port 501 and cooperates with the limiting cylinder 221 to form the diversion cavity 217. The housing assembly 20 is provided with an input port 203 communicating with the baffle chamber 217. Specifically, the first type of medium enters the diversion cavity 217 from the input port 203 and then flows into the flow through cavity 201 through the inner valve port 501. The second wall block 216 cooperates with the limiting cylinder 221 to form at least part of the boundary of the diversion cavity 217. More specifically, the first wall block 211, the second wall block 216 and the limiting cylinder 221 together form a boundary of the diversion cavity 217. Further, the first wall block 211 and the second wall block 216 may be integrally disposed, and the sealing member 24 may be disposed in a gap between the second wall block 216 and the limiting cylinder 221 to form a sealing fit. In another embodiment, the second wall block 216 may abut against the position-limiting cylinder 221 to form a sealing fit. Since the restraining cylinder 221 is separated from the second wall block 216 before the restraining cylinder 221 is assembled with the second wall block 216, the valve cartridge 50 is easily assembled into the housing assembly 20.

In some embodiments, as shown in fig. 3, the flow-through cavity 201 is divided into at least a front cavity section 203 and a rear cavity section 204 connected to the front cavity section 203. The first wall block 211 and the partition assembly 30 form an anterior chamber segment 203 therebetween. On a projection plane perpendicular to the direction of movement of the valve element 50, the front chamber section 203 and the rear chamber section 204 at least partially coincide. The rear chamber section 204 is at least partially co-located with the guide chamber 217 in a plane perpendicular to the direction of movement of the valve core 50. Specifically, the back cavity segment 204 communicates to the variable cavity 222 through a side hole 223. As shown in connection with FIG. 3, the housing assembly 20 also has an output port 204 that communicates with the rear chamber section 204. More specifically, the diversion cavity 217 and the rear cavity 204 are both disposed on a side of the front cavity 203 away from the partition assembly 30, and on a projection plane perpendicular to the movement direction of the valve core 50, the diversion cavity 217 and the rear cavity 204 can overlap at least part of the front cavity 203, and the variable cavity 222 is disposed on a side of the diversion cavity 217 opposite to the partition assembly 30, so that the diversion cavity 217, the variable cavity 222, and the flow through cavity 201 can be reasonably spatially disposed, which is beneficial to improving the compactness of the regulating valve 10, and can reduce the size of the section of the regulating valve 10 perpendicular to the movement direction of the valve core 50. In one embodiment, the rear cavity section 204 is disposed between the second wall block 216 and a sidewall 218 of the housing assembly 20. More specifically, the wall surface of the second wall block 216 is disposed perpendicular to the wall surface of the first wall block 211.

In one embodiment, as shown in connection with FIG. 3, the housing assembly 20 has an abutment portion 219. Assuming that the second type of medium in the adjustment chamber 202 provides a medium pressure F1 to the partition member 30, the elastic force provided by the elastic member 40 to the partition member 30 is F2, and the first type of medium in the through-flow chamber 201 provides a medium pressure F3 to the partition member 30, when the sum of F1 and F2 is greater than F3, the rod portion 219 can abut against the partition member 30 to limit the zoom variation range of the inner valve port 501. Before the regulating valve 10 is put into use, since the flow-through chamber 201 and the regulating chamber 202 are both at atmospheric pressure, and F1 and F3 are equal, the partition member 30 is moved in a direction to compress the flow-through chamber 201 by the elastic member 40. Under the action of the rod-abutting part 219, the stroke of the partition assembly 30 is limited, and the internal valve port 501 is not excessively enlarged before the regulating valve 10 is put into use, so that effective regulation is avoided when the first type of medium cannot flow due to the fact that the internal valve port 501 is excessively large. Further, the rod portion 219 is connected to a side of the first wall block 211 facing the partition member 30.

In some embodiments, as shown in fig. 2 and 3, the housing assembly 20 includes a main housing 21 and a cover plate 22. The main casing 21 has a first lid opening 213 and a second lid opening 214. The partition member 30 covers the first cap opening 213. The cover plate 22 covers the second cover opening 214. Specifically, the main housing 21, the partition assembly 30, and the cover plate 22 form the boundary of the through-flow chamber 201. By providing the first cover opening 213 and the second cover opening 214, the inside of the main casing 21 can be processed relatively easily. More specifically, the first cover port 213 is disposed opposite the second cover port 214 to facilitate the assembly of the valve cartridge 50. Further, the first wall block 211 and the second wall block 216 are disposed in the main casing 21, and the limiting cylinder 221 is connected to the cover plate 22, so that after the assembly of the cover plate 22 and the main casing 21 is completed, the abutting joint of the limiting cylinder 221 and the second wall block 216 can be completed at the same time. Further, the main housing 21 is detachably connected to the cover plate 22 by fasteners 60.

In some embodiments, as shown in fig. 2 and 3, the housing assembly 20 includes a housing cover 23 coupled to the main housing 21. The inner ring portion 31 abuts between the main housing 21 and the housing cover 23. The elastic member 40 is abutted between the cover 23 and the partition 32. Specifically, the inner ring portion 31 is held from both sides by the main case 21 and the case cover 23, so that both sides of the partition member 30 can be sealed, and the medium in the flow-through chamber 201 or the adjustment chamber 202 is prevented from leaking through the edge of the inner ring portion 31. More specifically, the casing cover 23 is provided with a feedback port 231, and the second medium of the outer flow passage 800 enters and exits the regulation cavity 202 through the feedback port 231. In one embodiment, the elastic member 40 is a compression spring, and both ends of the elastic member respectively abut against the housing cover 23 and the partition portion 32. Further, the main housing 21 is detachably connected to the housing cover 23 by fasteners 60.

In some embodiments, as shown in fig. 3 and 4, the partition assembly 30 has an inner ring portion 31 and a baffle portion 32. The inner ring portion 31 is disposed around the bulkhead portion 32. The inner ring portion 31 is flexible and cooperates with the baffle portion 32 to form an active boundary between the flow-through chamber 201 and the adjustment chamber 202. Specifically, as tuning cavity 202 expands relative to flow-through cavity 201, the diaphragm moves to one side of flow-through cavity 201. As the through-flow lumen 201 expands relative to the adjustment lumen 202, the barrier portion 32 moves to one side of the adjustment lumen 202. The inner ring portion 31 deforms accordingly as the diaphragm portion 32 moves. Further, the partition portion 32 has a relatively stable shape by itself or a relatively stable shape defined by other components, and the radius of the partition portion 32 is larger than the radial width of the inner ring portion 31, so that the volume change amount of the through-flow chamber 201 or the regulating chamber 202 and the displacement amount of the partition portion 32 form a nearly proportional relationship. In one embodiment, the bulkhead portion 32 has a certain stiffness to maintain a certain shape. In another embodiment, the partition assembly 30 further includes a clamping block 33 having a relatively stable shape compared to the partition portion 32, the clamping block 33 is disposed at one side of the partition portion 32, and the partition portion 32 is adhered to the clamping block 33, thereby stabilizing the shape of the partition portion 32. In another embodiment, as shown in fig. 3, a spacer portion 32 is provided between two clamping blocks 33 to maintain the shape. Further, the valve core 50 is threadedly coupled to one of the clamping blocks 33.

In some embodiments, as shown in fig. 3 and 4, the partition member 30 has an outer extension portion 34, and the outer extension portion 34 is connected to the outer edge of the inner ring portion 31. The main housing 21 is provided with a positioning groove 215, and the extension 34 is at least partially received in the positioning groove 215. Specifically, since the inner ring portion 31 receives a large medium pressure and has a deformation space, the inner ring portion 31 may be detached from the abutting edge between the main casing 21 and the casing cover 23 during the movement. Since the extension portion 34 is connected to the outer edge of the inner ring portion 31, and the extension portion 34 is located outside the abutting edge between the main casing 21 and the casing cover 23 and is accommodated in the positioning groove 215, a limiting effect can be exerted on the inner ring portion 31, and the medium leakage in the flow-through chamber 201 or the adjustment chamber 202 caused by the deformation and release of the inner ring portion 31 can be avoided. Further, the positioning groove 215 is annular, and the outward extending portion 34 is annular and is turned over relative to the inner ring portion 31, so that any angle of the inner ring portion 31 can be prevented from being loosened.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
