Abstract
The utility model discloses a throttle valve convenient to assemble. The throttle valve comprises a valve body, a valve core, a compression spring, an adjusting rod and a sealing plug, wherein two communicated valve holes are formed in the left side and the right side of the valve body, respectively; a valve core hole communicated with the valve holes is formed in the bottom of the valve body; the valve core, the compression spring, the adjusting rod and the sealing plug are all arranged inside the valve core hole; one end of the compression spring is welded with a valve core shaft, and the other end of the compression spring is connected with the adjusting rod, so that the valve holes are obstructed by the valve core; the adjusting rod is inserted inside the sealing plug and spirally connected with the sealing plug; the sealing plug and the valve core hole are spirally sealed. The throttle valve is convenient to install and can be installed at a high speed.
Description
Technical field
The utility model belongs to a kind of valve field, is specifically related to a kind of throttle valve easy to assembly.
Background technique
Traditional throttle valve needs in the spool bore at valve body, spool, stage clip, adjustable lever and seal plug to be installed successively when assembling, but also to make spool, stage clip, adjustable lever and seal plug coordinate each other, because spool bore is little, so assemble very inconvenient, and when valve body does not also process, the first-class parts of spool, stage clip, adjustable lever and seal plug just cannot be assembled, relative effect installation time.
Model utility content
(1) technical problem that will solve
The problem that will solve of the present utility model is to propose a kind of throttle valve easy to assembly.To connect the problem that solves assembling trouble in conventional art.
(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 assembly, comprise valve body, spool, stage clip, adjustable lever and seal plug, the left and right sides of described valve body arranges a valve opening being interconnected, the bottom of described valve body is provided with a spool bore being communicated with valve opening, described spool, stage clip, adjustable lever and seal plug are all arranged in spool bore, described stage clip one end and poppet shaft welding, the other end is connected spool is intercepted valve opening with adjustable lever, described adjustable lever is plugged in seal plug, and be connected with seal plug spiral, described seal plug and spool bore spiral seal.
Further also comprise handle; Described handle is arranged on valve body outside, and is fixedly connected with adjustable lever.
The axial vane surface of described spool comprises annular sealing gasket; The bottom surface fitted seal of described sealing gasket and spool bore.
Further also comprise seal ring, described seal ring is separately positioned between spool and seal plug and between seal plug and adjustable lever.
The material of described spool is stainless steel.
(3) beneficial effect
Throttle valve of the present utility model, by spool, stage clip, adjustable lever are cooperatively interacted and are connected with seal plug, thereby spool directly first can be installed, and then be plugged in throttle valve, reduced the difficulty of installing, and this structure can first install spool, stage clip, adjustable lever and seal plug, unnecessaryly wait valve body first to process to install again, relatively saved the time.
Accompanying drawing explanation
Fig. 1 is the structural representation of throttle valve easy to assembly of the present utility model;
Fig. 2 is the enlarged view of A portion in Fig. 1;
Fig. 3 is the sectional view of the B-B of Fig. 1;
In figure, 1 is that valve body, 2 is that spool, 3 is that stage clip, 4 is that adjustable lever, 5 is seal plug.6 is that valve opening, 7 is that spool bore, 8 is that handle, 9 is that sealing gasket, 10 is seal ring.
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 assembly as shown in Figure 1-Figure 3, comprise valve body 1, spool 2, stage clip 3, adjustable lever 4 and seal plug 5, the left and right sides of described valve body 1 arranges a valve opening being interconnected 6, the bottom of described valve body 1 is provided with a spool bore 7 being communicated with valve opening 6, described spool 2, stage clip 3, adjustable lever 4 and seal plug 5 are all arranged in spool bore 7, described stage clip 3 one end and poppet shaft 7 welding, the other end is connected with adjustable lever 4 intercepts 2 pairs of valve openings 6 of spool, described adjustable lever 4 is plugged in seal plug 5, and be connected with seal plug 5 spirals, thereby can regulate the length of stage clip 3, the pressure of further regulating spool 2.Described seal plug 5 and spool bore 7 spiral seals.When assembling, first adjustable lever 4 screw threads can be plugged in seal plug 5, by one end peach elder sister of stage clip 3 sick and spool welding on spool 2, the other end be socketed on adjustable lever 4, thereby the spool first assembling 2, stage clip 3, adjustable lever 4 and seal plug 5, then the parts after assembling are inserted in the spool bore 7 of valve body 1 and are tightly connected by seal plug 5, therefore make to install simpler, convenient.And without etc. valve body 1 whether produce and put in place, can be directly first by core 2, stage clip 3, adjustable lever 4 and seal plug 5, thus accelerated the speed of assembling.
In above-mentioned throttle valve, also comprise handle 8; Described handle 8 is arranged on valve body 1 outside, and is fixedly connected with adjustable lever 4, by handle 8, carrys out 4 rotations of regulating and controlling bar.
The axial vane surface of described spool 2 comprises annular sealing gasket 9; The bottom surface fitted seal of described sealing gasket 9 and spool bore 2, thus the sealing between spool and valve opening 6 strengthened.And spool 2 outer surfaces do not contact with the inwall of spool bore, can reduce the friction of power, improved the correctness of pressure.
In above-mentioned throttle valve, also comprise seal ring 10, described seal ring 10 is separately positioned between spool bore 7 and seal plug 5 and between seal plug 5 and adjustable lever 4.To improve sealing.
The material of described spool 2 is stainless steel.
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.
