Abstract

The utility model discloses a novel triangular valve structure, which relates to a valve device between pipelines. The triangular valve structure comprises a valve body, a water outlet pipe, a valve rod, a ball core and a handle, wherein the valve rod passes through the valve body, the outer end is fixedly connected with the handle, the inner end is connected with the ball core, and the water outlet pipe is connected with the valve body. The utility model is characterized in that the ball core is in a ball shape, a water through hole is arranged on the ball core, the inner side surface of the handle is provided with two convex strips, and a blocking head is arranged on a position on the valve body which corresponds to the inner side surface of the handle and can be in contact with the convex strips. The utility model has the advantages that the rotation angle of the handle is limited through cooperation of the blocking strips and the convex strips, and the opening and closing operation of a triangular valve can be generally realized only by rotating the handle through 90 degrees, so the operation is very convenient.

Description

A kind of novel triangle vavle structure

Technical field

The utility model relates to the valving between the pipeline, specifically is a kind of triangle vavle of new structure.

Background technique

At present, triangle vavle is a kind of valve that is widely used, in the triangle vavle structure on the existing market, spool adopts ceramic core mostly, though triangle vavle of ceramic core uses more convenient in this, life-span also is longer relatively, but its cost height, preparation process require height to cause its price relatively just higher.

The model utility content

It is a kind of rational in infrastructure that technical problem to be solved in the utility model is to provide, the novel triangle vavle of improvement, and it is low to have product cost, long service life.

Technical problem to be solved in the utility model realizes by the following technical solutions,

A kind of novel triangle vavle structure, comprise valve body, outlet pipe, valve rod, ball core and handle, described valve rod passes valve body, and outer end and handle are fixedly linked, and the inner is connected with the ball core, described outlet pipe is connected with valve body, it is characterized in that: described ball core is spherical in shape, is shaped on the water port on the ball core, and the inner side surface of described handle has two raised lines, position corresponding to the handle inner side surface on the valve body is provided with a retaining head, and described retaining head can contact with raised line.

When handle with sleeve, drive the ball core by valve rod and rotate, the opening and closing of control triangle vavle.In the handle with sleeve process, the retaining head on the valve body contacts with raised line, and the rotation angle of restriction handle makes triangle vavle accurately be in to close fully or the state of complete opening.

Between described outlet pipe and the valve body by being threaded.

The beneficial effects of the utility model are to match by blend stop and raised line, and the rotation angle of restriction handle only needs to rotate 90 ° of opening and closing operations that both can realize triangle vavle usually, and convenience very therefore operates.In assembling, be threaded between outlet pipe and the valve body simultaneously, be convenient to spool is enclosed in the valve body, make that whole assembly technology is simple.

Fig. 2 is an A-A generalized section among Fig. 1;

Fig. 3 is a B-B generalized section among Fig. 1;

Fig. 4 is a C-C generalized section among Fig. 1.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, a kind of novel triangle vavle structure is made of valve body 1, outlet pipe 4, valve rod 2, ball core 3 and handle 5.Valve rod 2 stretches out valve body 1, and its outer end is connected with handle 5, and its inner is connected with ball core 3.Valve rod 2 and handle 5 closely are fixed together by screw 6, and the outer end section of valve rod 2 is square, as shown in Figure 2.In novel triangle vavle structure, valve rod 2 can not rotate with respect to handle, and outlet pipe 4 is connected the side of valve body 1, and intake pipe 12 is in the bottom of valve body 1 and is connected as a single entity with valve body 1.

As shown in Figure 1, ball core 3 is spheroidal, is shaped on water port 31 in the ball core 3, and water port 31 is a T-shaped hole of running through, and pulls handle 5, by valve rod 2 transmissions ball core 3 is rotated, thereby opens or close triangle vavle.And between ball core 3 and valve body 1, be placed with seal washer 7, be used for seal action, and can prevent when triangle vavle is closed that the fluid in the pipeline from passing through.

As depicted in figs. 1 and 2, handle 5 is cup-shaped, handle 5 inner side surfaces have two raised lines 51, raised line 51 is parallel with valve rod 2, as shown in Figure 1 and Figure 4, is shaped on retaining 11 on valve body 1 outer side surface, retaining 11 is in the position of handle 5 inboards, in handle 5 rotation processes, retaining 11 can block raised line 51, thus the rotation angle of restriction handle 5.

As shown in Figure 4, article two, the handle inner side surface circular arc radian between the raised line 51 is 90 °, and raised line 51 can be limited in the rotation angle of handle 5 in 90 ° the scope, simultaneously like this, when retaining 11 when wherein a raised line 51 contacts, triangle vavle is in complete opening or complete closing state all the time.

As shown in Figure 1, outlet pipe 4 is by being threaded in the sidepiece of valve body 1, and the inner of outlet pipe 4 core 3 of trapping the ball makes ball core 3 location.

As shown in figures 1 and 3, in order to rotate outlet pipe 4, outlet pipe 4 is connected with valve body 1, inner side surface at outlet pipe 4 is shaped on teeth 41, in when assembling, as long as also being had the assembly tool that teeth and external diameter diameter be slightly less than outlet pipe 4 internal diameters, head is inserted in the outlet pipe 4, rotate assembly tool, just can drive outlet pipe 4 and rotate together, outlet pipe 4 is connected with valve body 1.

More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
