Description
Technical field
The utility model relates to a kind of safety check, especially relates to a kind of high-power program control focus safety check.
Background technique
At present, known focus has several as follows: spark source, weight bumping type focus, steam or high pressure gas-explosion-type focus, dynamite source etc.There is the defects such as the power device rapid wear that volume is large, the sequential filming time lag is very long, operation with high pressure is dangerous, expensive in spark source.Weight bumping type focus is that employing is little of tens kilograms, greatly to tens tons of direct colliding surfaces generation seismic wavess, the same powerful seismic waves that will produce needs up to a hundred kilograms or more heavy things, has that volume is large, quality heavy, carries inconvenience, very loaded down with trivial details, the high in cost of production shortcoming of operation.Steam or high pressure gas-explosion-type focus adopt steam-reforming to be kinetic energy, or directly launch with pressurized gas and produce seismic waves, and its efficiency is very low, and the shortcoming such as it is long to there is the sequential filming time lag, and programmed sequence of operations is loaded down with trivial details.Dynamite source is that to produce seismic waves power at present maximum, the focus that effect is best, but explosive belongs to national strict monitoring product, and need country's examination & approval, supervision is difficulty quite, and cost is high, has high risk.
In order to better utilize legal means to protect high-power program control focus, the utility model, as the critical component of high-power program control focus, is listed separately and is protected.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of structure simple, safe and reliable and is applicable to the high-power program control focus safety check of high-power program control focus.
The technical solution adopted in the utility model is: comprise valve body, spool, spring and guide pad, and described valve body is provided with mitre velve head bore and pilot hole, and valve head hole and pilot hole are coaxially and be communicated with; Described spool comprises cone-shaped valve head and connecting rod, and valve head is placed in valve head hole, and the end of connecting rod connects guide pad, described guide pad is provided with vent, guide pad is placed in the pilot hole of valve body, and described spring one end is connected with guide pad, and the other end is connected with valve body.
In above-mentioned high-power program control focus safety check, the small end of described mitre velve head bore is towards pilot hole; Valve head hole and pilot hole connectivity part forming station terrace on valve body, the small end of described cone-shaped valve head is connected with connecting rod; The end of connecting rod is connected with guide pad, and described spring is between step surface and guide pad, and be sleeved on connecting rod, one end is connected with step surface, and the other end is connected with guide pad.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model is the critical component of high-power program control focus, and effectively prevent combustion gas and oxygen mix to light explosion time, mixed gas refluxes along pipeline, causes the generation of gas explosion danger, makes high-power program control focus safe and reliable.
2. the utility model structure is simple, and easy to use, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of valve body of the present utility model.
Fig. 3 is the structural representation that the utility model is applied on high-power program control focus.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises valve body 1, spool 2, spring 4 and guide pad 3; As shown in Figure 2, described valve body 1 is provided with mitre velve head bore 11 and pilot hole 12, and valve head hole 11 and pilot hole 12 are coaxial and be communicated with, and valve head hole 11 and pilot hole 12 connectivity part form a step surface 13, and the small end of mitre velve head bore 11 is towards pilot hole 12.Described spool 2 comprises cone-shaped valve head 21 and connecting rod 22, and the small end of cone-shaped valve head 21 is connected with connecting rod 22; Described valve head 21 is placed in valve head hole 11, and the end of connecting rod 22 connects guide pad 3, and described guide pad 3 is provided with vent 31, and guide pad 3 is placed in the pilot hole 12 of valve body.Described spring 4, between step surface 13 and guide pad 3, is sleeved on connecting rod 22, and one end is connected with the step surface 13 of valve body 1, and the other end is connected with guide pad 3.
As shown in Figure 3, when the utility model is used for high-power program control focus, be arranged in the pore 51 on the valve seat 5 of high-power program control focus, valve head 21 of the present utility model is towards the torpedo shell 6 of high-power program control focus.When being filled with combustion gas and oxygen to torpedo shell 6, combustion gas or oxygen enter pilot hole 12 from the vent 31 of guide pad 3, then valve head 21 is promoted by gas pressure, valve head 21 pulls open spring 4 under gas pressure, be separated with valve head hole 11, combustion gas or oxygen enter torpedo shell 6 from the gap between valve head 21 with valve head hole 11 and mix.Igniting explosion time, due to blast, torpedo shell 6 internal air pressure increases, if do not have words of the present utility model, mixed gas and the heat of the burning that is not able to do in time can be advanced along gas pipeline and oxygen channel, likely cause gas explosion; And the utility model makes explosion time, valve head is pressed in mitre velve head bore by the air pressure in torpedo shell 6 and spring 4, prevent mixed gas and heat to advance along gas pipeline and oxygen channel, prevent the generation of gas explosion danger, make high-power program control focus safe and reliable.
