Description

A kind of inner elements of check valve

Technical field

The utility model relates to a kind of inner elements of check valve.Inner elements of check valve in particular for all kinds of diaphragm metering pump entrance ends.

Background technique

As shown in Figure 1, existing inner elements of check valve, body 1, body 1 central authorities establish passage 11, are provided with core body 2 in the Lower Half of body 1, are provided with the passage 21 of inverted cone in core body 2, are provided with vertically a plurality of fins 22 in vias inner walls.One spheroid 3 is located at also can be up and down along passage in passage 21.One base 4 is connected in the Lower Half of core body 2, establishes passage 41 on base.One seal ring 5 is connected in the joint between base 4 bottoms and spool.

During use, if fluid flows from lower to upper, promote spheroid 3 up, 3 of spheroids are stopped by fin 22, and fluid continues upwards to flow from the gap between fin and core body inwall.And when fluid is mobile from top to bottom, spheroid 3 moves down, thereby block the passage 41. of base 4, play the effect of one-way flow.

There is following deficiency in this one-way valve: the dead angle in core body is large, easily causes collection slag, if fluid is soda acid or organic solution, the easy aging distortion of seal ring, causes the series of problems such as leakage.

Model utility content

The purpose of this utility model is to provide a kind of inner elements of check valve, to solve the above-mentioned problems in the prior art.

The technological scheme that the utility model provides is as follows:

An inner elements of check valve, comprises body, core body, spheroid and base, and wherein core body is positioned at body, and the passage of core body and the passage of body communicate; Spheroid is positioned at the passage of core body and can moves up and down along the passage of core body, base is positioned at the passage lower end of core body, it is characterized in that: the upper end of the passage of described core body is provided with horizontal baffle plate. this baffle plate is provided with a plurality of openings that originate in the center of circle, radially distribute, and the length of each opening is greater than the radius of baffle plate.

In preferred embodiment of the present utility model, described opening is 3-6.

In preferred embodiment of the present utility model, described opening has four, is arranged as cross.

In preferred embodiment of the present utility model, described opening is three, is arranged as Y-shaped.

In preferred embodiment of the present utility model, Y-shaped row's opening, each interval 120 degree.

In preferred embodiment of the present utility model, in core body, establish passage, the diameter of this passage 21 is unanimous between the higher and lower levels; The lower end of passage is provided with the step of enlarged-diameter; The upper end of passage is provided with baffle plate, and this baffle plate is provided with cross opening, and opening surpasses the part of radius for being made as half round post; The top of baffle plate, is provided with the groove that diameter is greater than the diameter of passage.

In preferred embodiment of the present utility model: the passage upper end of base is made as inverted cone.

In preferred embodiment of the present utility model: the groove that diameter is greater than passage is established in the passage lower end of base.

Seen from the above description, the utility model provides a kind of inner elements of check valve,

1. spool two ends have increased groove diversion Design, the medium by spool more effectively, more concentrated, usefulness is realized and maximizes.

2. the outlet of spool is designed to cross intersection discharge port, has effectively reduced outlet dead angle, has effectively avoided spool collection slag.Thereby solved the problem that spool collection slag retains.

3. because spool import and export have adopted groove water conservancy diversion energy collecting design, by valve seat pressurization diversion groove, sealed, medium does not arrive in valve seat, therefore saved seal spool part.

Embodiment

Embodiment 1

Specific embodiment of the utility model, with reference to Fig. 2 to Fig. 5, a kind of inner elements of check valve, is comprised of body 1, core body 2 and spheroid 3 and base 4.

Wherein, the structure of body 1 and background technique is the same, also comprises passage 11.

Core body 2 is cylindrical shape, inside establishes passage 21, and the diameter of this passage 21 is unanimous between the higher and lower levels.The lower end of passage 21 is provided with the step 23 of enlarged-diameter.The upper end of passage 21 is provided with baffle plate 24. these baffle plates 24 and is provided with cross opening 25.Wherein, the length of this cross opening 25 is greater than the diameter of passage 21.Two ends surpass the part of diameter for being made as half-cylindrical 251.The top of baffle plate 24, is provided with the groove 26 that diameter is greater than passage 21 diameters.

Passage 41 upper ends of base 4 are made as inverted cone 42.Lower end is provided with the groove 43 of enlarged-diameter.

During installation, the Nei， upper end, lower end that base 4 is installed on core body 2 is resisted against on step 23.

Use of the present utility model is as follows: after installing, if fluid flows from lower to upper, through after the passage 41 of base 4, promote spheroid 3 up, 3 of spheroids are stopped by baffle plate 24, and fluid continues upwards to flow from cross opening 25.And when fluid is mobile from top to bottom, spheroid 3 moves down, thereby block the passage 41. of base 4, play the effect of one-way flow.

Because spool two ends have increased groove diversion Design (groove 43 with groove 26), the fluid by spool more effectively, more concentrated, usefulness is realized and maximizes.

2. the outlet of spool is designed to cross intersection discharge port 25, has effectively reduced outlet dead angle, has effectively avoided spool collection slag.Thereby solved the problem that spool collection slag retains.

3. because spool import and export have adopted groove water conservancy diversion energy collecting design (groove 43 and groove 26), by valve seat pressurization diversion groove (groove 43 and groove 26), sealed, medium does not arrive in valve seat, therefore saved seal spool part.

Embodiment 2

The basic structure of the present embodiment is identical with embodiment 1, and difference is that the opening on core body baffle plate 24 is arranged as Y shape, interval 120 degree between opening.

Above are only a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
