Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a multifunctional filter element piston angle valve. Background Art

[0002] The piston angle valve is a type of valve that can be used to control the flow of liquid.

[0003] Today's piston angle valves mainly open and close the valve based on the up and down movement of the piston. When air is supplied, compressed air enters the air control head and pushes the piston upward, overcoming the elastic force of the return spring. At the same time, the piston drives the valve stem and valve body to open the sealing disc, and the valve is in the open state. When no air is supplied, the return spring holds the sealing disc against the valve, and the valve is in the closed state.

[0004] However, current piston angle valves all require springs to be used in conjunction with them, which results in a complex internal structure and higher costs. To this end, we propose a multifunctional filter element piston angle valve. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-5 The multifunctional filter element piston angle valve shown includes a valve body 101 and a valve core assembly. The outer wall of the valve body 101 is provided with a liquid-passing assembly, which includes multiple liquid-passing pipes 501. The outer walls of the multiple liquid-passing pipes 501 are each provided with a second externally threaded groove 502. The liquid-passing pipe 501 at the bottom is connected to an external liquid supply device, allowing liquid to enter the valve body 101 through it and then be discharged through the two liquid-passing pipes 501 on both sides. In this application, the main body of the valve body 101 is a three-way structure. When liquid discharge from both ends is not required, a sealing cap can be screwed onto the outer wall of one of the liquid-passing pipes 501, thereby improving the functionality of the valve.

[0026] In a preferred embodiment, the valve core assembly is arranged inside the valve body 101, and the valve core assembly includes a valve seat 202. A connecting hole 201 is opened inside the valve body 101, and the valve seat 202 is arranged below the connecting hole 201. The top of the valve seat 202 is fixedly connected to the valve stem 203. An adjustment mechanism is provided above the valve stem 203. A filtering mechanism is provided inside the valve body 101. The outer diameter of the valve seat 202 is larger than the inner diameter of the connecting hole 201. When the valve stem 203 is raised in cooperation with the adjustment mechanism so that the valve seat 202 is against the stepped groove below the connecting hole 201, the bottom can enter the valve body 101. 1 cannot flow upward through the communicating hole 201. Only when the valve seat 202 is lowered and the valve seat 202 is separated from the stepped groove below the communicating hole 201, can the liquid flow out through the gap between the outer wall of the valve seat 202 and the inner wall of the valve body 101 and the gap between the outer wall of the valve stem 203 and the inner wall of the communicating hole 201 in sequence. As the distance between the valve seat 202 and the stepped groove increases, the water flows faster. Therefore, the valve can be controlled by only raising and lowering the valve stem 203, which improves the convenience of valve control operation and does not require the use of a spring, making the valve cost lower.

[0027] Among them, the adjustment mechanism includes an adjustment seat 301, which is inserted into the inner wall of the valve body 101. The bottom end of the adjustment seat 301 is provided with an extrusion hole 302. The top of the valve stem 203 is fixedly connected with a plurality of extrusion rods 204.

The filtering mechanism is provided at the bottom end of the adjustment seat 301. When the adjustment seat 301 moves downward in the valve body 101, the filter mechanism is provided. When the adjusting seat 301 is moved upward, the extrusion rod 204 can be inserted upward into the extrusion hole 302, so that the liquid enters the valve body 101 through the liquid pipe 501 below. The liquid will squeeze the valve seat 202, causing the valve seat 202 to rise, so that the valve seat 202 can be pressed against the stepped groove, thereby closing the valve.

[0028] Among them, the connecting mechanism includes a first external thread groove 401, the first external thread groove 401 is opened on the outer wall of the adjusting seat 301, and the inner wall of the valve body 101 is opened with an internal thread groove 402. The outer wall of the first external thread groove 401 is threadedly connected to the outer wall of the internal thread groove 402, and the top of the adjusting seat 301 is fixedly connected with a protrusion 403. Through the cooperation of the first external thread groove 401 and the internal thread groove 402, the height of the adjusting seat 301 can be controlled by rotating the adjusting seat 301, thereby improving the working stability of the adjusting mechanism. At the same time, the protrusion 403 facilitates the screwing of the adjusting seat 301, thereby improving the convenience of operation of the adjusting mechanism.

[0029] Among them, the outer wall of the valve stem 203 is fixedly connected to a plurality of fixing plates 601 in a circular array, and the outer wall of the fixing plate 601 is arranged to fit the inner wall of the connecting hole 201. Through the setting of the fixing plate 601, the movement of the valve stem 203 in the connecting hole 201 is smoother.

[0030] Among them, the outer wall of the valve seat 202 is provided with a first annular groove 701, and the inner wall of the first annular groove 701 is sleeved with a first rubber sleeve 702. Through the setting of the first rubber sleeve 702, the valve seat 202 can be sealed after it rests against the stepped groove, thereby ensuring the stability of the valve closing.

[0031] Among them, the outer wall of the adjustment seat 301 is provided with multiple second annular grooves 801, and the inner wall of the second annular groove 801 is provided with a second rubber sleeve 802. Through the setting of the second rubber sleeve 802, the liquid in the valve body 101 cannot flow out through the gap between the valve body 101 and the adjustment seat 301, thereby improving the stability of the valve operation.

[0032] Among them, the filtering mechanism includes a connecting pipe 901, the top end of the connecting pipe 901 is fixedly connected to the bottom end of the adjustment seat 301, and a plurality of filter grooves are provided on the outer wall of the connecting pipe 901. The liquid entering from the bottom liquid pipe 501 will pass through the filter groove and then enter the liquid pipes 501 on both sides for discharge, thereby filtering impurities in the liquid, further improving the functionality of the valve.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
