Abstract
The invention relates to a water check valve structure capable of improving the water inlet speed. The water check valve structure comprises a water check valve seat and is characterized in that a mounting cavity is formed in the water check valve seat; a water inlet hole connected with a water inlet pipeline and a water outlet hole connected with a water outlet pipeline are respectively formed in the mounting cavity; the water inlet hole is positioned in the transverse position of the mounting cavity; the water outlet hole is positioned in the lower part of the mounting cavity; a water check element is arranged in the mounting cavity of the water check valve seat and comprises a cylinder, a sealing element at the upper end of the cylinder as well as a spring fixing post positioned on the sealing element; the lower end of the cylinder is arranged in the water outlet hole; multiple annular water conducting chutes distributed in the circumferential direction of the cylinder are formed in the surface of the cylinder; the spring fixing post is sleeved by a spring; one end of the spring props against the upper surface of the sealing element; the other end of the spring props against the upper end of the mounting cavity. According to the water check valve structure disclosed by the invention, by changing the water guiding chute structure on the surface of the water check element in the prior art, a certain water inlet speed can be guaranteed, and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of water stop valve structure improving water intake velocity, especially a kind of water stop valve structure on filter, belongs to technical field of water treatment equipment.
Background technique
Current filter or water transfer facility often can use water check valve, and existing water stop valve structure is all generally seal component that can be movable by one, makes aqueduct be communicated with or block under different states.Seal component common is at present generally cylindrical shape, and when water check valve is in open mode, water source is flow through by the water chute between seal component and pipeline.The shortcoming that this form exists is that water intake velocity is slow.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of water stop valve structure improving water intake velocity is provided, ensures certain water intake velocity, increase work efficiency.
According to technological scheme provided by the invention, the water stop valve structure of described raising water intake velocity, comprise sealing valve seat, it is characterized in that: in described sealing valve seat, be provided with installation cavity, installation cavity arranges the water inlet be connected with intake pipe and the osculum be connected with outlet conduit respectively, water inlet is positioned at the lateral attitude of installation cavity, and osculum is positioned at the below of installation cavity; In the installation cavity of described sealing valve seat, seal component is set, seal component comprises cylindrical body, the seal of cylindrical body upper end and the spring fixed column that is positioned on seal, cylindrical lower end is arranged in osculum, is provided with the annular water chute of multiple tracks along cylindrical body circumferential directions on cylindrical surface; Sheathed spring on described spring fixed column, the upper surface of seal is withstood in one end of spring, and the other end of spring withstands the upper end of installation cavity.
Arrange groove in the upper end of described osculum, the size of this groove and the matching size of seal close, and arrange seal ring in a groove.
The water stop valve structure of raising water intake velocity of the present invention, by changing the water chute structure of sealing element surface in prior art, can ensure certain water intake velocity, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of described seal component.
Embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 1 ~ Fig. 2: as described in the water stop valve structure of raising water intake velocity comprise sealing valve seat 1, installation cavity 2, water inlet 3, osculum 4, seal component 5, cylindrical body 6, seal 7, spring fixed column 8, water chute 9, spring 10, groove 11, seal ring 12 etc.
As shown in Figure 1, the present invention includes sealing valve seat 1, in sealing valve seat 1, be provided with installation cavity 2, installation cavity 2 arranges the water inlet 3 be connected with intake pipe and the osculum 4 be connected with outlet conduit respectively, water inlet 3 is positioned at the lateral attitude of installation cavity 2, and osculum 4 is positioned at the below of installation cavity 2; In the installation cavity 2 of described sealing valve seat 1, seal component 5 is set, as shown in Figure 2, seal component 5 comprises cylindrical body 6, the seal 7 of cylindrical body 6 upper end and the spring fixed column 8 that is positioned on seal 7, the lower end of cylindrical body 6 is arranged in osculum 4, is provided with the annular water chute 9 of multiple tracks along cylindrical body 6 circumferential directions on the surface of cylindrical body 6; Sheathed spring 10 on described spring fixed column 8, the upper surface of seal 7 is withstood in one end of spring 10, and the other end of spring 10 withstands the upper end of installation cavity 2;
As shown in Figure 1, arrange groove 11 in the upper end of described osculum 4, the size of this groove 11 and the matching size of seal 7 close, and arrange seal ring 12 in groove 11; When seal 7 is arranged in groove 11, seal ring 12 can play seal action, and anti-sealing enters osculum 4 by water inlet 3.
Working principle of the present invention: in use, cylindrical body 6 is up pushed away, thus water flows into installation cavity 2 by water inlet 3, then the multiple tracks ring water chute 9 through cylinder 6 surface flows into osculum 4, flows into outlet conduit by osculum 4.When closing water check valve, the power that cylindrical body 6 lower end applies is removed, now, originally the spring 10 be compressed produces tension force, promote cylindrical body 6 to move toward osculum 4 direction, seal 7 is placed in groove 11, thus osculum 4 is closed, to avoid water to flow into osculum 4 by water inlet 3, play the effect of sealing.
