Abstract
The utility model discloses a shunt valve of a coal cutter. The shunt valve of the coal cutter comprises a valve body, a sealing part and a plurality of valve cores. A water inlet channel and a plurality of water outlet branch circuits are respectively arranged in the valve body, and the water outlet branch circuits are communicated with the water inlet channel. The sealing part is installed on the top portion of the water inlet channel. The plurality of valve cores are respectively inserted in the valve body and block all the water outlet branch circuits. One end of the water inlet channel is a water inlet, and the other end of the water inlet channel is a standby connector. The sealing part comprises a screw plug and a sealing ring, wherein the screw plug is connected with the standby connector of the water inlet channel in an inserted mode, and the sealing ring is sleeved on the screw plug. The shunt valve is simple in structure and small in occupied space. The design of a water supply pipe of the coal cutter is simplified, and the installation efficiency is improved.
Description
Technical field
The utility model relates to a kind of coal winning machine water supply installation, is specifically related to a kind of coal winning machine shunt valve.
Background technique
Existing shunt valve is exactly a spool left-right rotation, always seals by the footpath; This valve core of water isolating valve moves up and down, by axial seal.The past water valve is that frictionally pins, and this shunt valve is lived by nut back of the body deadlock, and this method is safety more firmly, avoids vibration influence.
The total water of coal winning machine is that a water pipe supplies water, and needs to be divided into several branch roads after machine, because every required cooling water flow of branch road is different.Need not have again individual branch road that the flow that water valve is regulated each branch road is set separately for this reason.
The model utility content
The utility model provides a kind of coal winning machine shunt valve, and this diversion valve structure is simple, takes up room little, has simplified the design of coal winning machine supply channel, and has improved installation efficiency.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of coal winning machine shunt valve is characterized in, comprises:
Valve body is respectively equipped with intake tunnel and several water outlet branch roads in described valve body, described water outlet branch road and intake tunnel connect;
Sealed member, described sealed member is arranged on the end of intake tunnel;
Several spools, described spool intert respectively in valve body and block every water outlet branch road.
Described intake tunnel one end is made as water intake, and its other end is made as spare interface.
Described sealed member comprises plug screw and seal ring; Described plug screw is plugged on the spare interface of intake tunnel; Described seal ring is nested with on plug screw.
This shunt valve also comprises O type circle, and described O type circle is arranged between spool and valve body.
A kind of coal winning machine shunt valve of the utility model compared with prior art has the following advantages:
A kind of coal winning machine shunt valve of the utility model, this diversion valve structure is simple, takes up room little, has simplified the design of coal winning machine supply channel, and has improved installation efficiency.

Embodiment
Below in conjunction with accompanying drawing, by describing a better specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1 and Figure 2, a kind of coal winning machine shunt valve, comprise: valve body 1, sealed member, four spools 5 and O type circle 6 are respectively equipped with intake tunnel 2 and four water outlet branch road 3(referring to Fig. 4 in described valve body 1), described water outlet branch road 3 connects with intake tunnel 2; Described sealed member is arranged on the end of intake tunnel 2; Described spool 5 interts respectively in valve body 1 by screw thread and blocks every water outlet branch road 3(referring to Fig. 3), tighten locking at the top of spool 5 by nut 7.Described intake tunnel 2 one ends are made as water intake, and its other end is made as spare interface, and described O type circle 6 is arranged between spool 5 and valve body 1.
Described sealed member comprises plug screw 41 and seal ring 42; Described plug screw 41 is plugged on the spare interface of intake tunnel 2; Described seal ring 42 is nested with on plug screw 41.
As shown in Figure 1, when the utility model is used, the water pipe of outside is inserted into the water inlet of intake tunnel 2, current are through four water outlet branch roads 3 and flowed out by water outlet, reach the purpose that coal winning machine divides water, the rotation by spool 5 simultaneously comes regulating water flow, tightens locking by nut 7 after regulating.
In sum, the utility model provides a kind of coal winning machine shunt valve, and this diversion valve structure is simple, takes up room little, has simplified the design of coal winning machine supply channel, and has improved installation efficiency.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
