Background technique
At present, on oil field gas wellhead equipment and various device,, inside screw stop valve and pressure gauge are installed respectively in the radial position of container in order to measure the pressure in well head and the equipment; When changing pressure gauge, need close stop valve and just can dismantle pressure gauge, if stop valve leaks fault in occurring, with the entail dangers to person and device security; Simultaneously, again befouling environment, have disaster hidden-trouble.
The model utility content
The purpose of this utility model is: a kind of pressure meter valve that has one-way valve is provided, can directly be connected with pipeline, realize just directly loading and unloading pressure gauge without throttle down.Also can play the blowout prevention effect in the absence of stop valve.
The technical solution adopted in the utility model is: the pressure meter valve that has one-way valve, mainly form by pressure gauge, valve seat, Support cushion, sealing gasket, valve ball, spring and valve body, the valve seat outer wall is cylindric, two parallel rectangular faces that symmetry is arranged in the middle of the external cylindrical surface, rectangular face are used for the card spanner.It is characterized in that: the valve seat two ends have internal thread respectively, and valve seat upper end internal thread specification is M20 * 1.5, and lower end internal thread specification is ZG1/2 ".On the internal thread of valve seat upper end, be fixed with pressure gauge, be fixed with the annular brace pad at manometric entry end.The outer wall end of Support cushion is a cone-shaped.Between the internal thread of valve seat two ends diaphragm is arranged, diaphragm has center hole, and center hole upper half part is cylindrical, and lower half portion of center hole is a conical surface shape.The Support cushion lower end enters valve seat diaphragm center hole and to pressing down valve ball after screwing pressure gauge.
Be fixed with valve body on the internal thread of valve seat lower end, valve outer wall is cylindric, and there is outside thread at the valve body two ends, and valve body upper external screw thread specification is ZG1/2 ", lower end outside thread specification is M20 * 1.5.The upper end is the one-way valve inner chamber in the valve body, and pressure spring and valve ball are arranged in the one-way valve inner chamber.Spring pushes away valve ball, and valve ball is withstood on the conical surface of valve seat.There is center hole lower end at valve seat, valve seat lower end center hole UNICOM one-way valve inner chamber.
In order to improve sealing, on the hole wall of the conical surface shape center of valve seat, annular groove is arranged, at the annular groove internal fixation seal ring is arranged.
In order to make pressure gauge be tightened on valve seat, the pressure in the cavity between pressure gauge and the valve seat can unload out, on the outer wall of valve seat screw is arranged, and at the screw internal fixation release screw is arranged.
Between the upper-end surface of valve body and valve seat diaphragm lower plane, the circular ring sealing gasket is arranged.
The installation process that has the pressure meter valve of one-way valve: consult Fig. 1.When unloading pressure gauge 1,, unload loose release screw 4 earlier, gas in emitting table, dismounting again after the pressure release because spring and interior pressure effect valve ball seal up valve seat; During setting pressure table 1, Support cushion 3 step cylindrical opening slot directions are put into valve body 2 endoporus down, tighten release screw 4, make pressure gauge 1 and valve body 2 to be threaded and to compress the end face of Support cushion 3.Support cushion 3 is depressed valve ball 7, the seal ring 5 that valve ball 7 is broken away from the valve body 2 inner conical faces.Container inner pressure enters pressure gauge 1 by axial bore, can show force value.
The beneficial effects of the utility model: the utility model has the pressure meter valve of one-way valve, can directly be connected with pipeline, and behind setting pressure table on the valve body, one-way valve is in opening state; After unloading pressure gauge, one-way valve is in automatic closed condition, also can play the blowout prevention effect in the absence of stop valve.
