Abstract
(B /) the utility model discloses a guide's formula high temperature stop valve, its characterized in that: which comprises the following components: a valve body, a valve cove, case subassembly and valve rod, imported runner is established on the valve body right side, the export runner is established in the valve body left side, the import runner communicates with each other with the export runner through the serious offense discharge orifice that the valve body inner chamber was equipped with, the case subassembly includes big case and little case, in the activity of valvelet core is located and is enclosed the cavity that by big case and case gland, the valve rod lower extreme is connected with the valvelet core, the valve gap hole is passed to the valve rod upper end and the valve gap top is followed toward stretching out outward in the sealed back of packing box, the upward movement of big case is spurred by the valvelet core, big case bottom is equipped with the small offence discharge orifice that has a perfect understanding imported runner and export runner, in the valve closed condition, the serious offense discharge orifice is stopped up downwards to big case, the small offence discharge orifice is stopped up downwards to little case, the fixed sleeve that is equipped with of valve body inner chamber, the sleeve is equipped with the upper and lower activity of the interior pore pair gate valve core of cylinder and leads. The utility model discloses can realize that the low thrust is opened and is closed, the reliable operation stable, improve life.
Description
Technical field
The utility model relates to a kind of improvement invention of high temperature break valve.
Background technique
Because the import and export of valve exist pressure reduction, this must produce unbalanced force to the spool top and bottom of high temperature break valve, in order to overcome the impact that this unbalanced force produces the opening and closing of valve, most of producer can select high thrust final controlling element to solve this problem.But select the price of high thrust final controlling element can be very high, and the specific pressure allowable of sealing surface may be exceeded because thrust is excessive, sealing surface is damaged, and its weight also corresponding increase is a lot, give to install and transport is made troubles.For this reason, claimant has applied for the utility model patent of the patent No. 201220622490.5, patent name " double spool cutting-off controlling valve " on November 22nd, 2012, and the technology that this patent provides solves above-mentioned Problems existing preferably.But in practical work process, big valve core easily produces swing under fluid impact, have a strong impact on reliability and stability and the working life of valve working.
Summary of the invention
In view of current known technology Problems existing, the technical problems to be solved in the utility model is to provide a kind of leading type high temperature break valve realizing low thrust opening and closing, reliable and stable work, raising working life.
The utility model is implemented by the following technical programs:
Leading type high temperature break valve, it is characterized in that: comprise valve body, valve gap, mangetic core assembly and valve rod, inlet channel is established on the right side of valve body, outlet flow is established on the left of valve body, the large flowing hole that inlet channel is provided with through body cavity communicates with outlet flow, mangetic core assembly comprises big valve core and small valve core, small valve core activity is located in the cavity that crossed by big valve core and spool gland, valve rod lower end is connected with small valve core, valve rod upper end is stretched out from valve gap top outward through after valve gap endoporus and packing box seal, moving upward of big valve core is pulled by small valve core, the little flowing hole of through inlet channel and outlet flow is provided with bottom big valve core, at valve-closed state, big valve core blocks large flowing hole downwards, small valve core blocks little flowing hole downwards, body cavity is fixed with sleeve, sleeve is provided with Cylinder inner bore and leads to the up and down of big valve core.
The epimere of small valve core mills out Hexagon cylinder.
Advantageous Effects of the present utility model is: 1. the opening and closing being realized low thrust by large small valve core combination, during valve closing, medium enters valve pocket from import on the right side of valve body and arrives big valve core and small valve core upper surface, the little corresponding suffered unbalanced force of small valve core lifting surface area is also little, valve final controlling element in opening process can mention small valve core easily, when the small valve core medium that moves up just can arrive valve body left side outlet by little flowing hole pressure is released, valve pocket internal pressure is made to reach a state of equilibrium, small valve core continues to move up when reaching the stroke of small valve core, small valve core just can drive big valve core to move up easily, until valve is opened completely, 2. big valve core in the course of the work all the time sleeved Cylinder inner bore it is led, thus the swing effectively avoided fluid impact and cause, make valve working reliable and stable, improve working life, 3. small valve core epimere milling Hexagon cylinder can solve the problem that medium drives big valve core to rotate when flow velocity is large.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
