The simplified check valve of the present utility model will now be described in more detail with reference to the drawings, in which preferred embodiments of the present utility model are shown, it being understood that one skilled in the art could modify the utility model described herein while still achieving the beneficial effects of the present utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.
The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.
As shown in fig. 1, an embodiment of the present utility model provides a simple check valve, which includes a valve body 1, a sealing body 2, and a driving member.
Specifically, the bottom and the top of the valve body 1 are respectively provided with an inlet chamber 3 and an outlet chamber 4, a sealing seat 5 is arranged between the inlet chamber 3 and the outlet chamber 4, and the inlet chamber 3 and the outlet chamber 4 are respectively connected with an inlet channel 6 and an outlet channel 7.
The sealing body 2 is matched with the sealing seat 5, and the sealing seat 5 channel is blocked when the sealing body 2 is in close contact with the sealing seat 5.
The driving piece is detachably arranged on the valve body 1 and is used for driving the sealing body 2 to be in contact with the sealing seat 5.
In the present embodiment, when the check valve works, the water flow lifts up the sealing body 2, and at this time, the inlet chamber 3 is communicated with the outlet chamber 4, so that the normal flow of the water flow can be performed; when the water flow is closed or the water flow reversely flows, the sealing body 2 falls onto the sealing seat 5 under the drive of the driving piece and seals the water flow passage, and the check valve is in a closed state.
Further, the sealing seat 5 is provided with a channel slot 8 matched with the sealing body 2, and the sealing body 2 is in contact with the side wall of the channel slot 8.
Specifically, the sealing body 2 adopts sphericity, and sealing body 2 and passageway groove 8 phase-match, and when rivers appear flowing backward or forward rivers stop, sealing body 2 falls into passageway inslot 8 and closely pastes with passageway groove 8 inner wall under the drive of driving piece, and sealing body 2 shutoff is to passageway groove 8, and the check valve is in the closed state this moment.
When the water flow positively flows, the water flow pressure jacks up the sealing body 2, the sealing body 2 is separated from the channel groove 8, the channel groove 8 is opened, and the check valve is in an opened state.
In a specific embodiment, in order to improve the tightness between the sealing body 2 and the inner wall of the channel groove 8, a sealing gasket is arranged on the side wall of the channel groove 8.
Further, an arc-shaped limiting cavity for limiting the sealing body 2 is formed in the valve body 1, and after the sealing body 2 moves to the arc-shaped limiting cavity, the channel groove 8 is opened.
Specifically, the inside arc spacing chamber that sets up of valve body 1 can be when sealing body 2 is jacked have the activity space for sealing body 2 and sealing seat 5 separation, the check valve is in the open state this moment. In addition, when the sealing body 2 is not subjected to the jacking force, the sealing body 2 can fall into the channel groove 8, so that the closing of the check valve is realized.
Further, the driving piece comprises a fixing seat 9, the fixing seat 9 is installed on the valve body 1 in a threaded mode, and an adsorption magnet 10 used for magnetically attracting the sealing body 2 to enter the channel groove 8 is arranged on the side wall of the fixing seat 9.
Specifically, the driving piece adopts detachable mode to install on valve body 1, and when absorption magnet 10 magnetic force weakens and makes reverse sealed effect not good, the accessible changes the driving piece and can realize, conveniently maintains.
In addition, when the water flows in the forward direction, the lifting force of the water flow to the sealing body 2 is larger than the magnetic attraction force of the attraction magnet 10, and at this time, the sealing body 2 is lifted, and the check valve is in an open state. When the water flow stops or the water flow flows reversely, the driving part adsorbs and fixes the sealing body 2 on the sealing seat 5, and the reverse closing of the check valve is realized at the moment.
The attracting magnet 10 may be a conventional magnet. The valve can also be an electromagnet, so that the magnetic force can be adjusted, and the closing and opening of the check valve can be actively realized.
In a specific embodiment, the fixing seat 9 is provided with a fastening sleeve 11, the fastening sleeve 11 is used for screwing the fixing seat 9 on the valve body 1, and the fastening sleeve 11 and the fixing seat 9 are integrally formed. When the driving piece is required to be replaced, the wrench is used for rotating the fastening sleeve 11, and the operation is convenient and simple.
In order to avoid contact between the attracting magnet and the liquid, a shield 12 is provided outside the attracting magnet.
Compared with the prior art, the utility model has at least the following beneficial effects:
the utility model realizes the one-way opening function of the check valve by utilizing the attraction of the driving piece to the sealing body, and in addition, the driving piece adopts a detachable mounting mode, thereby being convenient for replacing the driving piece, meanwhile, the spring is not used, the influence of the rust of the spring in the valve body on the one-way tightness of the check valve is avoided, and the utility model has the characteristics of simple structure and convenient maintenance.
