Description
Technical Field
The invention relates to an improved invention of a filtering triangular valve, which can be used for filtering impurities in tap water before the tap water enters a water appliance (such as a tap and the like), and can conveniently clean a filter screen by utilizing a special structure, thereby having good application value.
Background
With the improvement of the living standard of people, household water appliances tend to be high-end and intelligent, and meanwhile, the high-grade appliances have high requirements on water quality, and the impurities possibly enter to cause faults, so that various filter screens are arranged in the appliances, and the cleaning of the filter screens is very troublesome. It is necessary to filter the tap water before it enters the water-consuming device, and the filtering step is properly carried out on the triangular valve of the water outlet. The filtering triangular valve in the prior art has the technical problems of inconvenient cleaning, short service life, unstable performance and the like. An easy-to-clean filtering triangular valve with inconvenient cleaning products such as CN 201220380625.1. The product basically sets the filter screen cover, the hand wheel switch and the like respectively, when the filter screen is cleaned, the hand wheel switch is required to be closed firstly, then the tool is used for opening the filter screen cover, and the filter screen is taken out for cleaning, so that the filter screen is obviously inconvenient. Whereas the prior art filtering triangular valve with CN99226171.6 has the following contents: the filtering triangular valve comprises a shell, a water stop valve, a control body and a filter screen, wherein the shell comprises a water inlet end, a water outlet end and a control valve chamber communicated with the water inlet end and the water outlet end, a water inlet valve port is arranged between the water inlet end and the control valve chamber, and an opening is formed in the control valve chamber outwards; the water stop valve is combined with an elastic element to be elastically and correspondingly arranged at the water inlet valve port, and the elastic element can correspondingly push the water stop valve to close the water inlet valve port; the control body comprises a cover body and a push rod connected with the cover body, the cover body is correspondingly assembled at an opening of a control valve chamber of the shell in a removable way, and the push rod pushes the water stop valve to leave the water inlet valve port; the filter screen is assembled in the control valve chamber and is positioned between the water inlet end and the water outlet end. The water stopping structure of the technology adopts the function of closing the angle valve by pressing the rubber seal head by the elastic element and the water pressure, and simultaneously realizes the opening of the angle valve by reversely pressing the rubber seal head by the ejector rod. The disadvantage of this structure is: when the water pressure is too small or the rubber seal head is attached with sundries, the phenomenon that water cannot be completely shut off can be generated; meanwhile, the rubber material is easy to age, so that the service life is short; also, the technology can not realize rapid and accurate water quantity adjustment and the like; there is a need for a more structurally sound filtering triangular valve to meet our needs.
Disclosure of Invention
The invention relates to an improved filtering triangular valve.
In order to solve the technical problem, the invention is realized in the following way that the filtering triangle valve comprises a shell, a water stop valve, a control body and a filter screen, wherein the shell comprises a water inlet end, a water outlet end and a valve cavity communicated with the water inlet end, a water inlet valve port is arranged between the valve cavity and the water inlet end, and a valve cavity water outlet and a water outlet valve port are arranged between the valve cavity and the water outlet end; the water stop valve is provided with an adjusting shaft; the control body is provided with a clamping position; the method is characterized in that: the water stop valve is fixedly arranged above the water inlet valve port in the valve cavity; a filter cavity is arranged between the water outlet of the valve cavity and the water outlet valve port; the filter screen is positioned in the filter cavity; the control body is connected with the adjusting shaft on the water stop valve through the clamping position in the control body to realize the opening and closing of the water stop valve; the control body is provided with a locking position A; the shell is provided with a locking position B; the combination or separation of the control body and the shell is realized through the relative movement of the locking position A and the locking position B; the locking direction of the locking position A and the locking position B is consistent with the opening direction of the water stop valve, namely, the water stop valve is in a water outlet state when the locking position A and the locking position B are locked.
The control body is provided with a water through hole; the locking position A is arranged below the control body and is protruded to the outer side of the control body; the locking position B is arranged at the bottom of the inner side of the shell and corresponds to the locking position A; the locking position B is provided with a guide groove and a concave position.
An elastic element is arranged between the control body and the water stop valve.
The water stop valve is a ceramic-sheet-sealed valve core capable of being opened and closed quickly.
The filter screen is communicated with the water through hole, is arranged on the inner wall of the control body and forms a whole with the control body.
The elastic element is a spring.
A one-way valve is arranged in the water outlet end.
The check valve is fixed by clamping the clamp spring into the clamping groove.
The filtering triangle valve is provided with a shell, a water stop valve, a control body and a filter screen, and the water stop valve is provided with an adjusting shaft; the control body is provided with a clamping position; the water stop valve is a valve core which is sealed by ceramics and is opened and closed quickly; therefore, after the water stop valve is fixedly arranged above the water inlet valve port in the valve cavity, the filtering triangular valve can be quickly opened and closed by utilizing the connection of the clamping position on the control body and the adjusting shaft on the water stop valve. Because the filter cavity is arranged in the shell, the filter screen is positioned in the filter cavity, and meanwhile, the filter screen is arranged on the inner wall of the control body and forms a whole with the control body; therefore, when the filter screen is required to be taken out, the filter screen can be realized only by taking down the control body. The control body is movably connected with the shell by virtue of the relative action of the locking position A and the locking position B; during specific operation, the control body with the filter screen can be pushed into the shell along the guide groove on the locking position B by utilizing the positioning of the locking position A, and when the control body is pushed into the control body, the clamping position inside the control body is simultaneously connected with the adjusting shaft on the water stop valve. The combination or separation of the control body and the shell is realized by the relative movement of the locking position A and the locking position B; and the locking direction of the locking position A and the locking position B when being matched is consistent with the opening direction of the water stop valve. Therefore, when the control body is vertically pushed into the shell to be in place, the control body only needs to be rotated, and at the moment, the locking position A is clamped by the concave position on the locking position B, so that the two parts are locked, and the water stop valve is also opened. When the control body is taken out to clean the filter screen, the opposite process operation can be easily realized. And an elastic element is arranged between the control body and the water stop valve. The elastic element is a spring. The arrangement of the spring can reduce the precision requirement of product processing, avoid unstable product component combination and have good use effect. If we need to wash the filter screen, only need the rotation control body to close the triangular valve and go out water, at this moment, locking position A can withdraw from locking position B in step and go into the guide groove, receive the effect of spring elasticity, at this moment the control body will be to the direction automatic displacement who leaves the casing. Thus, the control body with the filter screen is easier to take out. A one-way valve is arranged in the water outlet end. The check valve is fixed by clamping the clamp spring into the clamping groove. The one-way valve has the advantages that the function of the angle valve is well perfected, the one-way water inlet function of the angle valve is realized, the phenomenon of countercurrent and series flow during water use is avoided, and the reliability of water use is improved.
The invention has the advantages that:
1. the water stop valve is a valve core which is sealed by a ceramic plate and is rapidly opened and closed, so that the stability of quality is ensured, and the service life is longer. But also can conveniently and randomly regulate the water flow.
2. The control body and the filter screen are integrally designed, the locking groove and the guide groove are arranged at the same time, and the spring is arranged between the control body and the water stop valve, so that the integral combination is very convenient when the filter screen is cleaned, and the filter screen can be easily taken out for cleaning by only rotating and closing the triangular valve without any tool. Meanwhile, when the triangular valve is in a state of being opened or closed incompletely, the filter screen cannot be taken out, so that the need of judging whether the triangular valve is in a closed state or not when the filter screen is disassembled is avoided.

Because the locking position A (32) is arranged below the control body (3), the structure is that the locking position A protrudes to the outer side of the control body (3); the locking position B (13) is arranged at the bottom of the inner side of the shell (1) and corresponds to the locking position A (32); the locking position B (13) is provided with a guide groove (15) and a concave position (16). The adjusting shaft (23) is provided with a straight tooth A (24), and the clamping position (34) is also provided with a straight tooth B (35) matched with the straight tooth A (24). When the locking position A (32) below the control body (3) is aligned with the guide groove (15) and the control body (3) with the filter screen (4) and the spring is integrally and longitudinally pushed into the shell (1), the clamping position (34) provided with the straight teeth B (35) in the control body (3) is normally connected with the adjusting shaft (23) provided with the straight teeth A (24); the control body (3) is pushed into place and rotated, so that the locking position A (32) is screwed into the concave position (16), and the water stop valve (2) is opened under the action of the straight teeth A (24) and the straight teeth B (35) due to the adjusting shaft (23) and the clamping position (34); the control body is provided with the sealing ring (33), so that the filter cavity (85) can be sealed. Finally, the one-way valve (6) is placed into the water outlet end (88), and meanwhile the clamp spring (7) is clamped into the clamping groove (14) to fix the one-way valve. Thus, the assembly of the entire filtering triangular valve is completed.
The filtering triangle valve is practically applied as follows: the water inlet end (81) of the filtering triangle valve is mounted to a tap water pipe while the water outlet end (88) is connected to a water appliance such as a faucet. Then the control body (3) is rotated anticlockwise, the water stop valve (2) can be opened, and the control body (3) can reach the maximum water supply only by rotating by 90 degrees because the water stop valve is a ceramic-plate-sealed valve core which is opened and closed rapidly. After the waterway is opened, tap water enters from the water inlet end (81), passes through the water inlet valve port (82), passes through the water stop valve (2), the valve cavity water outlet (84), enters the filter cavity (85), passes through the filter screen (4) and the water through hole (86), finally passes through the water outlet valve port (87) and finally reaches the water inlet of the faucet through the one-way valve (6). When the filter screen (4) needs to be cleaned, the control body (3) is only required to be rotated clockwise, the water outlet is completely closed, the control body (3) can automatically move outwards under the action of the elastic element (5), namely the spring force, and then the control body (3) is only required to be pulled out, and the filter screen (4) inside the control body is cleaned.
