Abstract
The utility model relates to a valve, in particular to a novel check valve and belongs to the field of machining. The novel check valve comprises an end cover, a body, a gasket, a valve seat and a spring seat. The valve seat is fixed on the end cover, and the spring seat is fixed on the body. A disc valve is arranged between the valve seat and the spring seat, and eight disc valve teeth are arranged on the disc valve. A spring groove is formed in the disc valve, and a spring is arranged between the spring seat and the spring groove. According to the novel check valve, due to the fact that face sealing is utilized by the check valve, so that the stiffness coefficient of the spring is reduced, and the opening pressure is reduced. The novel check valve is suitable for being used for steam or water or other media. In addition, the novel check valve is reasonable in structural design, convenient to use, overhaul and maintain.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of non-return valve, belongs to field of machining.
Background technique
In fields such as chemical industry, pharmacy, the use of safety check is seen everywhere.Safety check claims again check valve, one-way valve or check valve, and its effect is to prevent medium directional flow in pipeline and the function of unlikely refluence.The working principle of spring loaded check valve is, liquid flows into valve body by import, relies on the spring controlled flap of pressure jack-up, and after pressure disappeared, spring force was depressed flap, and sealing liquid flows backwards.Yet common safety check is most adopts the seal rings sealing, and such design seal ring in use easily damages, and it is large to open the cracking pressure of valve.
Therefore, in order to solve above technical problem, being necessary to have now design improves, designed a kind of non-return valve, this safety check is provided with plate valve, comes the one-way flow of control media by the opening and closing of crossing plate valve, because this safety check seals with employing face, reduce spring rate, make cracking pressure reduce.This safety check is applicable to the use of the media such as steam or water.In addition, this check valve structure is reasonable in design, and is easy to use, easy access and maintenance.
The model utility content
In order to overcome the defective that exists in background technique, the technological scheme that its technical problem that solves the utility model adopts is: a kind of non-return valve, comprise end cap, body, packing ring, valve seat and spring seat, described valve seat is fixed on end cap, described spring seat is fixed on body, is provided with plate valve between described valve seat and spring seat, and described plate valve is provided with 8 plate valve teeth, described plate valve is provided with spring groove, is provided with spring between described spring seat and spring groove.
A kind of non-return valve that the utility model is related, this safety check is provided with plate valve, comes the one-way flow of control media by the opening and closing of crossing plate valve, with the sealing of employing face, reduces spring rate due to this safety check, makes cracking pressure reduce.This safety check is applicable to the use of the media such as steam or water.In addition, this check valve structure is reasonable in design, and is easy to use, easy access and maintenance.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the plan view of a kind of non-return valve of the utility model;
Fig. 2 is the figure that analyses and observe the place of A-A direction in Fig. 1;
Fig. 3 is the figure that analyses and observe the place of B-B direction in Fig. 1;
Wherein: 1, end cap; 2, body; 3, packing ring; 4, valve seat; 5, spring; 6, spring seat; 7, spring groove; 8, plate valve; 9, plate valve tooth.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.The schematic diagram of accompanying drawing for simplifying basic structure of the present utility model only is described in a schematic way, so it only shows the formation relevant with the utility model.
See also Fig. 1, Fig. 2 and Fig. 3, a kind of non-return valve, comprise end cap 1, body 2, packing ring 3, valve seat 4 and spring seat 6, described valve seat 4 is fixed on end cap 1, described spring seat 6 is fixed on body 2, is provided with plate valve 8 between described valve seat 4 and spring seat 6, and described plate valve 8 is provided with 8 plate valve teeth 9, described plate valve 8 is provided with spring groove 7, is provided with spring 5 between described spring seat 6 and spring groove 7.
A kind of non-return valve that the utility model is related, in use, medium enters safety check from the end cap side, due to the existence of pressure medium, pressure can promote plate valve 8 and make spring contraction, and at this moment medium will pass through in the space between plate valve tooth 9, when pressure medium disappears, spring will recover elastic strain, and the elastic force of spring can make plate valve be close to valve seat, thereby medium can't be flow backwards.In a word, this safety check is provided with plate valve, comes the one-way flow of control media by the opening and closing of crossing plate valve, with the sealing of employing face, reduces spring rate due to this safety check, makes cracking pressure reduce.This safety check is applicable to the use of the media such as steam or water.In addition, this check valve structure is reasonable in design, and is easy to use, easy access and maintenance.
