Abstract

The utility model provides a check valve with an inclined seal port. The check valve comprises an upper valve body, a lower valve body, a seal ring, a valve core, the seal port, a seal rubber piece and a bolt, wherein the seal port is installed inside the lower valve body, and the seal port is an end port with 12 to 18 degree inclination; the valve core is hinged with the lower valve body; the seal ring is installed between the upper valve body and the lower valve body, and the upper valve body is fixedly connected with the lower valve body; the upper valve body is connected with an inner tube end port through the seal rubber piece; and furthermore, the seal port is the end port with 15 degree inclination. The check valve has the advantages that by means of the technical scheme, the check valve can be installed arbitrarily during installation of pipes, the check valve can be installed perpendicular to the pipes, and the check valve can also be installed in parallel with the pipes; the check valve is time-saving, labor-saving, and convenient to operate; and the check valve is simple in structure, convenient to maintain, low in manufacturing cost and the like.

Description

A kind of safety check with the inclination sealed mouth

Technical field

The utility model belongs to the valve arrangement technical field, especially relates to a kind of safety check with the inclination sealed mouth.

Background technique

In existing technology, general check valve seal mouth is vertical valve body direction, can only use when pipeline is vertical.Exist when keeping flat such as pipeline valve body to keep flat and then can not seal the generation leakage, must do a vertical arrangement, the expense that wastes time and energy space, the technical problem such as impracticable.

Summary of the invention

Problem to be solved in the utility model provides a kind of safety check with the inclination sealed mouth, especially is fit to horizontal pipe and uses simultaneously compatible vertical pipe to use.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of safety check with the inclination sealed mouth, comprise upper valve body, lower valve body, seal ring, spool, sealed mouth, caulking gum sheet and bolt, be provided with sealed mouth in the described lower valve body, described sealed mouth is that gradient is the port of 12 to 18 degree; Described spool and lower valve body are hinged; Seal ring and being fixedly connected with between described upper valve body and the lower valve body; Described upper valve body is connected by the caulking gum sheet with the inner tube port of lower valve body.

Further, described sealed mouth is that gradient is the port of 15 degree.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme so that safety check when pipeline is installed, installs arbitrarily, but vertical pipe install, but also horizontal pipe is installed; Time saving and energy saving, more convenient to operate; Have simple in structure, easy to maintenance, the advantage such as processing cost is low.

Fig. 1 is structural representation of the present utility model;

Among the figure:

1, lower valve body 2, caulking gum sheet 3, spool

4, sealed mouth 5, seal ring 6, bolt

7, upper valve body

Embodiment

As shown in Figure 1, a kind of safety check with the inclination sealed mouth of the utility model, comprise upper valve body 7, lower valve body 1, seal ring 5, spool 3, sealed mouth 4, caulking gum sheet 2 and bolt, be provided with sealed mouth 4 in the described lower valve body 1, described sealed mouth 4 is the port of 15 degree for gradient; Described spool 3 and lower valve body 1 are hinged; Seal ring 5 and being fixedly connected with between described upper valve body 7 and the lower valve body 1; Described upper valve body 7 is connected by caulking gum sheet 2 with the inner tube port of lower valve body 1.

The working procedure of this example: when safety check vertically uses, lower valve body 1 below, upper valve body 7 is in the above.

When the safety check level is used, its sealed mouth 4 tips below, the recessed end of sealed mouth 4 is upper.

Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
