Abstract
The utility model discloses a throttle valve convenient to use. The throttle valve comprises a valve body, an elastic valve core, a stop pin, a spring and a sealing screw. The valve body comprises a main flow channel from the top to the bottom and a blocking groove. The elastic valve core is inserted into the valve body transversely and penetrates the main flow channel to separate the main flow channel. A lateral flow channel is arranged on one side of the main flow channel, two ends of the lateral flow channel are communicated with the upper side and the lower side of the main flow channel respectively, the blocking groove is formed between the main flow channel and the lateral flow channel, the stop pin, the spring and the sealing screw are arranged in the blocking groove, the stop pin penetrates the blocking groove through the pressure of the spring to separate the main flow channel and the lateral flow channel, and the sealing screw is connected with the blocking groove in a sealing mode. The throttle valve is very convenient to use.
Description
Technical field
The utility model belongs to a kind of throttle valve field, is specifically related to a kind of throttle valve easy to use.
Background technique
Traditional throttle valve is mainly made up of valve body and spool, described throttle valve includes a throttle orifice, described spool is plugged in throttle orifice, carry out the flowpath pressure of regulation valve body by the degree of depth of pegging graft, but such regulative mode makes the degree of depth that spool pegs graft, (degree of depth of particularly pegging graft is crossed when dark, thereby can reduce the pressure of runner), so adjusting is very accurate, therefore regulate very trouble.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is convenient while making the degree of depth of regulating spool.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of throttle valve easy to use, comprises valve body, Elastic valve core, backing pin, spring and sealing screw; Described valve body includes sprue and a stifled groove from top to bottom, described Elastic valve core transverse splicing is in valve body and interted sprue and make sprue intercept, one side of described sprue includes a side runner, the two ends of described side runner are communicated with the both sides up and down of sprue respectively, described stifled groove is arranged between sprue and side runner, described backing pin, spring and sealing screw are installed in stifled groove, the pressure of described backing pin by spring is through stifled groove and to intercepting sprue and side runner, and described sealing screw and stifled groove are tightly connected.
Described sprue is made up of multiple longitudinal runners and horizontal runner.
Described Elastic valve core interts in longitudinal runner.
The two ends of described side runner respectively runner and a longitudinal runner horizontal with are communicated with.
Described stifled groove is arranged between a horizontal runner and side runner, and described backing pin is to intercepting between sprue and side runner.
(3) beneficial effect
Throttle valve easy to use of the present utility model, by sprue one side at valve body, side runner is set in addition, and a flexible backing pin is installed in order to intercept sprue and side runner, thereby the degree of depth that can Elastic valve core is crossed and is taken an advanced study into the pressure of obstruct and cause the partially liq of sprue the inside to reflux when excessive, thereby back down backing pin, liquid is flowed in the sprue of water outlet from side runner, thereby without making the degree of depth of Elastic valve core too accurate, therefore regulate very convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of throttle valve easy to use of the present utility model;
Fig. 2 is the enlarged view of A in Fig. 1;
Fig. 3 be in Fig. 1 B to view;
In figure 1 be valve body, 2 for Elastic valve core, 3 for backing pin, 4 for spring, 5 for sealing screw, 6 for sprue, 7 for stifled groove, 8 be side runner.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Throttle valve a kind of easy to use as shown in Figure 1-Figure 3, described throttle valve easy to use comprises valve body 1, Elastic valve core 2, backing pin 3, spring 4 and sealing screw 5, described valve body 1 includes sprue 6 and a stifled groove 7 from top to bottom, described Elastic valve core 2 transverse splicings are in valve body 1 and interted sprue 6 and make sprue 6 intercept, one side of described sprue 6 includes a side runner 8, the two ends of described side runner 8 are communicated with the both sides up and down of sprue 6 respectively, described stifled groove 7 is arranged between sprue 6 and side runner 8, described backing pin 3, spring 4 and sealing screw 5 are installed in stifled groove 7, the pressure of described backing pin 3 by spring 4 is through stifled groove 7 and to intercepting sprue 6 and side runner 8, described sealing screw 5 is tightly connected with stifled groove 7.
Described sprue 6 is made up of multiple longitudinal runners and horizontal runner.
Described Elastic valve core 2 interts in longitudinal runner.The two ends of described side runner respectively runner and a longitudinal runner horizontal with are communicated with.
Described stifled groove 7 is arranged between one of them horizontal runner and side runner 8, and described backing pin 3 is to intercepting between sprue 6 and side runner 8.And stifled groove 7, backing pin 3 and spring 4 are longitudinal installation, this structure can make the liquid that refluxes runner longitudinally longitudinally back down, and liquid is flowed to downwards in sprue from side runner 8.
When the inserting depth of Elastic valve core 2 is crossed when dark, thereby increase the pressure of spool 2, the backflow thereby the liquid that makes sprue 6 in water intake is obstructed, this liquid upwards refluxes and backs down backing pin 3 and flow to side runner 8, flows to downwards in the sprue 6 of water outlet, thereby normally discharge along side runner 8, therefore make can discharge from side runner because of Elastic valve core 2 liquid that deeply cannot not discharge of pegging graft, so without the inserting depth of accurate adjustable elastic spool 2, thereby regulate very convenient, laborsaving.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
